ʻO kēia ka nānā pono ʻana i ka laina, hui pū me ke kaʻina hana hoʻokahi, ka hopena i kahi lole e hāʻawi i ka hui hana maʻamau ma hope o ka pūʻulu - he pono koʻikoʻi no nā mea hana membrane bituminous, ka poʻe e hilinaʻi nei i ka hoʻoikaika like ʻana e hana i nā huahana wai wai pono.

Nā mea kiko'ī: Hoʻopili ʻia i nā pono o ka membrane bituminous

WINIW Nonwoven Spunbond Polyester Fabric for Bituminous Membranes ua hana ʻia me nā kikoʻī e kūlike me nā koi o ka hana ʻana i ka bituminous membrane.. ʻO kēlā me kēia ʻāpana - mai ka haku ʻana a hiki i ka laulā - e hoʻomaikaʻi i ka lōʻihi o ka membrane, hiki wai wai, a me ka maʻalahi o ka hana. Aia ma lalo iho kahi wehewehe kikoʻī o kā mākou kikoʻī kikoʻī:

1. Huina: 100% Polyester (PET) Nā Uila lōʻihi

Hoʻohana wale mākou 100% poliester (polyethylene terephthalate, PET) nā kaula lōʻihi (lōʻihi >100mm) - kahi koho i alakaʻi ʻia e nā waiwai kūʻokoʻa o ka polyester i ʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe (e.g., polypropylene, kīʻaha aniani) no ka hoʻoikaika ʻana i ka membrane bituminous:

• Palekana Kemika: ʻAʻole inert ka PET i ka bitumen (asphalt) a me kāna mau mea hoʻohui (e.g., nā mea hoʻololi e like me SBS, APP). ʻAʻole like me ka polypropylene (hiki ke hoʻohaʻahaʻa i ka wā e ʻike ʻia ai i nā pūhui ʻala o ka bitumen i ka manawa), Mālama ʻo PET i kona ikaika a me kona ʻano ma hope o ka launa pū ʻana me ka asphalt wela (a hiki i 200 ° C i ka wā o ka hana membrane).
• Pale ʻana i ka wai: Hoʻopili ʻo PET <0.5% o kona kaumaha i ka wai (vs. 8–10% no ka pulupulu a i ole 3–5% no ka hulu hipa), ka hōʻoia ʻana ʻaʻole e pehu ka lole a nalo paha i ka ikaika ma nā wahi haʻahaʻa - koʻikoʻi no ka hoʻoheheʻe ʻana i ka wai o lalo a me nā noi lining tunnel..
• Paʻa UV: Loaʻa i ka PET ka pale UV, e mālama ana i ka 70-80% o kona ikaika tensile ma hope 1000 hola o ka ʻike ʻana o UV (no ASTM G154). No nā noi waho (e.g., kaupaku), Hāʻawi mākou i kahi mea hoʻohui UV stabilizer koho e hoʻonui i ka paʻa i 85-90%, hoʻonui i ke ola lawelawe o ka membrane i 20+ makahiki.
• Pōmaikaʻi Filament lōʻihi: Nā kaula lōʻihi (vs. nā lālā koʻikoʻi pōkole) hoʻopau i ka hoʻoheheʻe ʻana i ka fiber — he pilikia maʻamau me nā mea ulana ʻole i hiki ke hoʻopaʻa i nā mea hana asphalt a hana i nā wahi nāwaliwali o ka membrane.. ʻO nā filament lōʻihi hoʻi e hoʻonui i ka ikaika tensile a me ke kūpaʻa puncture, ʻoiai lākou e puʻunaue i ke koʻikoʻi ma luna o ka hale lole holoʻokoʻa.

No nā noi kūikawā (e.g., nā membrane i hoʻohana ʻia i nā ʻano anuanu), hāʻawi mākou i kahi hui fiber PET / aniani (90% PET + 10% kīʻaha aniani) ʻo ia ka mea e hoʻomaikaʻi hou ai i ka maʻalahi haʻahaʻa haʻahaʻa (koena ductile ma -40°C) ʻoiai e mālama ana i ka pale kemika o polyester. Eia naʻe, ko makou hae 100% Ua kūpono ka lole PET i nā pono o 95% o ka hoohana ana i ka bituminous membrane, ke kaulike ana i ka hana a me ka uku-pono.

2. Kaumaha: 100–250gsm (Hoʻopololei kaulike & Ka ikaika)

Kaumaha lole (grama no ka mika square, gsm) pili pololei i ka hana o ka membrane bituminous hope loa - hāʻawi nā lole māmā i ka maʻalahi no nā ʻano paʻakikī, ʻoiai nā lole ʻoi aku ka kaumaha e hāʻawi i ka hoʻoikaika ʻana i nā wahi koʻikoʻi. Hoʻolālā ʻia kā mākou pae kaumaha e uhi i nā ʻano membrane maʻamau, me ka paʻa pono (±3gsm) hōʻoia ʻia e ka nānā ʻana i ka laina:

2.1 Māmā (100–150gsm): Hiki no ka Curved & Nā noi kikoʻī

He kūpono no nā membrane i hoʻohana ʻia i ka hale noho (ʻoi aku ma kahi o nā kapuahi, puka makani, a me nā mea ʻē aʻe), nā papa hana wai wai liʻiliʻi, a me ka wai o loko (e.g., nā lumi ʻauʻau). waiwai nui:

• mānoanoa: 0.3–0.5mm
• Ikaika U'i: 300–400 N/5cm (MD), 250–350 N/5cm (CD)
• Elongation ma ka Haka: 20–25%
• Hoʻololi: Hiki ke pio i ka 180° (ma kahi o 2cm anawaena mandrel) me ka pohā ʻole - koʻikoʻi no ka hoʻohālikelike ʻana i nā ʻaoʻao curved.

Laʻana: Ke hoʻohana nei kahi mea hana membrane hale ʻEulopa i kā mākou lole 120gsm no kā lākou laina membrane "maʻalahi-hoʻokomo". ʻO ka maʻalahi o ka lole e hiki ai ke hoʻopili ʻia ka membrane a puni nā ʻaoʻao o ka hale a me ke komo ʻana me ka ʻole o ka creasing, reducing the risk of leaks at these vulnerable points.

2.2 Kaumaha kaumaha (200–250gsm): Strength for High-Stress & Large-Scale Projects

Designed for commercial roofing (e.g., warehouse roofs with foot traffic), civil engineering projects (road base waterproofing, tunnel liners), a me nā laina hoʻopaʻa ʻāina. waiwai nui:

• mānoanoa: 0.6–0.8mm
• Ikaika U'i: 450–600 N/5cm (MD), 400–500 N/5cm (CD)
• Elongation ma ka Haka: 15–20%
• ʻoʻoleʻa: Higher rigidity (Shore A hardness 70–75) e pale i na ukana kaumaha (e.g., construction equipment on road projects) me ka deformation ole.

Laʻana: A Chinese civil engineering firm uses our 250gsm fabric in bituminous membranes for highway tunnel liners. The fabric’s high tensile strength resists the pressure of surrounding soil and groundwater, while its stiffness ensures the membrane maintains its shape during installation (even when draped over uneven tunnel surfaces).

3. Laulā: Up to 400cm (4m) – Maximizing Efficiency & hana

Our fabric’s maximum width of 400cm (4 mika) is a key advantage for bituminous membrane manufacturers, ʻoiai e kamaʻilio pololei ana i ʻelua mau wahi ʻeha koʻikoʻi: ka hana pono a me ka pono o ka membrane.

Hoʻemi kēia i ka manawa splicing (e 50-75% no nā membrane 4m ākea) a hoʻonui i ka wikiwiki laina hana e 20-30%.
• Hoʻemi ʻia ka ʻōpala: ʻO ka lole liʻiliʻi e koi pinepine i ka ʻokiʻoki e like me ka laulā o ka membrane, ka hopena i ka 5-10% o ka ʻōpala mea. Hiki ke hoʻopilikino ʻia kā mākou laulā 400cm (e.g., 3m, 3.5m) e kūlike i ka nui o ka membrane pololei o ka mea hana, e hoemi ana i ka hoopau i <2%.

3.2 Nā Pōmaikaʻi Hana Membrane

• Kaʻuʻuku o nā wahi hāʻule: ʻO nā hili ka ʻāpana nāwaliwali loa o ka membrane bituminous - hiki ke komo ka wai inā ʻaʻole i hoʻopaʻa pono ʻia nā hili.. He membrane 4m ākea i hana ʻia me kā mākou lole 50% liʻiliʻi liʻiliʻi ma mua o kahi membrane 2m ākea, e hōʻemi nui ana i ka hopena o ka leaks. Ma na hoao kahua, ʻO nā membrane i hana ʻia me ka lole 400cm he a 60% haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma mua o nā mea i hana ʻia me ka lole 200cm.
• Hoʻoikaika Kaulike: Hiki ke hana i ka mānoanoa like ʻole ma nā hili, e alakaʻi ana i ka uhi ʻana i ka asphalt like ʻole a me nā wahi nāwaliwali. ʻO kā mākou lole laula hoʻokahi e hōʻoia i ka hoʻoikaika like ʻana ma waena o ka membrane holoʻokoʻa, pela ka hana ana (e.g., kūʻē kūʻē, ikaika tensile) ua kūlike mai ka ʻaoʻao a i ka ʻaoʻao.

No nā mea hana me nā laina hana liʻiliʻi (e.g., nā mea e hana ana i nā membrane 2m ākea), hāʻawi mākou i nā laulā maʻamau (100knm–400cm) me ka liʻiliʻi liʻiliʻi o nā kauoha no nā hoʻololi ākea - e hōʻoia i kā mākou lole e hoʻohui pono i nā kahe hana.

Nā ana hana nui (no EN 13867, ʻO ke ʻano hoʻāʻo maʻamau no ka hoʻoholo ʻana i ka hoʻohana ʻana i ka asphalt o Geotextiles):

• Ka Laki Hoʻomoe Asphalt: 0.8–1.2 kg/m² (no ka lole 100–150gsm) - Hoʻopili ka lole i ka 80-100% o ka asphalt i hoʻohana ʻia i ka wā o ka uhi ʻana (typically 1–1.5 kg/m²). This ensures no excess asphalt remains on the surface (which can crack) or under the fabric (which can cause delamination).
• Paʻa Paʻa: 5–8 N/cm (force required to peel the fabric from asphalt) — 30–50% higher than the industry minimum of 3 N/cm. A high bond strength ensures the fabric and asphalt move together during temperature-induced expansion/contraction, preventing shear stress.
• Uniform Absorption: <5% variation in asphalt absorption across the fabric’s width — critical for consistent membrane performance. Inline thickness monitoring ensures the fabric’s porosity is uniform, so asphalt penetrates evenly.

The fabric’s structure enables this absorption: the needle-punched web creates millions of tiny pores (20–50 μm in size) that act as channels for molten asphalt. As the asphalt cools, it hardens within these pores, creating a mechanical lock between the fabric and asphalt. This lock is far stronger than the adhesive bond of fabrics with non-porous surfaces (e.g., some thermal-bonded nonwovens).

A Turkish membrane manufacturer tested our 150gsm fabric against a competitor’s thermal-bonded polyester fabric. Their results showed:

• Our fabric’s bond strength was 6.5 N/cm vs. the competitor’s 3.2 N/cm.
• Ma hope 1,000 cycles of temperature cycling (-20°C to 60°C), our fabric showed 0% delamination, while the competitor’s fabric delaminated in 15% of test samples.

The manufacturer switched to our fabric, reducing their membrane failure rate by 40%.

Nā noi: Where Our Fabric Delivers Unmatched Value

WINIW Nonwoven Spunbond Polyester Fabric for Bituminous Membranes is versatile enough to meet the demands of diverse construction and waterproofing projects. Below is a detailed breakdown of its key applications, with recommended specifications and real-world performance data:

1. Roofing Systems: Hale noho, Commercial & ʻOihana

Roofing is the largest application for bituminous membranes, and our fabric is engineered to address the unique challenges of each roof type — from small residential roofs to large industrial facilities with heavy foot traffic.

1.1 Residential Roofing

Residential roofs require membranes that are flexible (to fit around chimneys, puka makani, and dormers), māmā (to avoid straining the roof structure), a mau loa (to withstand 15–20 years of weather). Manaʻo kikoʻī:

• Kaumaha: 100–120gsm
• Laulā: 200–400cm (customized to roof size)
• Koho: UV hoʻopaʻa (for roofs with no overhangs, exposed to direct sunlight)

Nā pōmaikaʻi:

• Hoʻololi: Conforms to curved surfaces without creasing, reducing leak risk at penetrations.
• Māmā: Adds <0.5 kg/m² to the roof’s weight (vs. 1–1.5 kg/m² for glass fiber reinforcement), ideal for wooden roof structures.
• Kūʻai-Pono: The 100–120gsm weight balances performance and affordability, suitable for residential budgets.

Real-World Example: A U.S. home builder used our 110gsm fabric in bituminous membranes for 500 new homes in Florida (exposed to high humidity and occasional hurricanes). Ma hope 5 makahiki, roof inspections found zero leaks related to membrane failure — a 70% improvement over their previous membrane (i hooikaikaia me ka jute i ulana ole ia).

1.2 Commercial Roofing

Commercial roofs (e.g., office buildings, retail centers) often have HVAC equipment, foot traffic for maintenance, and large surface areas. They require membranes with high puncture resistance and strength. Manaʻo kikoʻī:

• Kaumaha: 150–200gsm
• Laulā: 400knm (to minimize seams)
• Koho: Fire-retardant finish (to meet building codes for commercial structures)

Nā pōmaikaʻi:

• Puncture Resistance: Withstands foot traffic and tool drops, reducing repair costs.
• Laulā laula: 400cm fabric cuts seams by 50% vs. 200cm fabric, lowering leak risk.
• Ka lōʻihi: 15–20 year service life, aligning with commercial building maintenance cycles.

Real-World Example: A European retail chain installed our 180gsm fabric-reinforced membranes on 20 warehouse roofs (kēlā me kēia 10,000 m²). The 400cm width reduced installation time by 30%, and the fabric’s puncture resistance meant no repairs were needed after 3 years of HVAC maintenance traffic — saving the chain €150,000 in annual repair costs.

1.3 Industrial Roofing

Industrial roofs (e.g., hale hana, power plants) face extreme conditions: nā wela kiʻekiʻe (from industrial processes), chemical exposure (e.g., uahi, fumes), and heavy loads (e.g., nā panela lā). They require the strongest, most chemical-resistant membranes. Manaʻo kikoʻī:

• Kaumaha: 200–250gsm
• Laulā: 400knm
• Nā mea hoʻohui: UV hoʻopaʻa + chemical-resistant finish (to withstand industrial fumes)

Nā pōmaikaʻi:

• Ka Ikaika Kiekie: Resists the weight of solar panels (a hiki i 15 kg/m²) without stretching.
• Palekana Kemika: Withstands exposure to industrial gases (e.g., sulfur dioxide) without degrading.
• Paʻa wela: <1% shrinkage at 200°C, suitable for roofs near high-temperature equipment.

Real-World Example: A Chinese steel mill used our 250gsm fabric-reinforced membranes on its factory roof (exposed to high temperatures and sulfuric acid fumes). Ma hope 4 makahiki, the membranes showed no signs of chemical degradation, and the roof required no major repairs — a stark contrast to the previous membrane (which needed replacement every 2 makahiki).

2. Basement Waterproofing: New Construction & Renovation

Basements are prone to water infiltration from groundwater, ua, a me ka haʻahaʻa. Bituminous membranes reinforced with our fabric create a seamless waterproof barrier that protects against moisture damage (e.g., poʻo, structural rot).

2.1 New Construction Basements

For new builds, membranes are applied directly to the foundation (concrete or masonry) before backfilling. Manaʻo kikoʻī:

• Kaumaha: 120–150gsm
• Laulā: 300–400cm (to cover foundation walls in one piece)
• Key Property: Moisture expansion <0.5% (prevents swelling against the foundation)

Nā pōmaikaʻi:

• Ka uhi ʻole: Wide width reduces seams on foundation walls, where water pressure is highest.
• Adhesion: High asphalt absorption bonds the membrane tightly to the foundation, preventing water from seeping between the membrane and substrate.
• Mildew Resistance: Polyester’s low moisture absorption prevents mold growth on the fabric.

Real-World Example: A Canadian home builder used our 140gsm fabric in bituminous membranes for 200 basement foundations in Toronto (where the water table is high). Post-construction inspections found 99% of basements were completely dry — up from 85% with their previous membrane.

2.2 Basement Renovations

Renovations require membranes that are easy to install in tight spaces (e.g., existing basements with low ceilings) and compatible with older foundations. Manaʻo kikoʻī:

• Kaumaha: 100–120gsm (lighter weight for easier handling)
• Laulā: 150–200cm (more maneuverable in tight spaces)
• Key Property: Hoʻololi (180° bend without cracking)

Nā pōmaikaʻi:

• Hoʻokomo maʻalahi: Māmā, narrower fabric can be carried through basement doors and maneuvered around existing pipes and fixtures.
• Conformability: Flexibility allows the membrane to follow uneven surfaces in older foundations, ensuring full coverage.
• Hoʻolikelike: Bonds well with both new and existing concrete, making it ideal for renovation projects where the foundation may have minor cracks or irregularities.

Real-World Example: A U.K. renovation company used our 110gsm fabric in bituminous membranes for 50 basement conversions in London (many in historic buildings with uneven stone foundations). The fabric’s flexibility allowed it to conform to the foundations’ irregularities, ka hopena i ka 90% reduction in post-renovation water leaks compared to their previous membrane.

3. Civil Engineering Projects: ʻOihana & Large-Scale Developments

Civil engineering demands the most robust materials, as projects like roads, tunnels, and landfills face constant stress from traffic, groundwater, and environmental conditions. Our fabric-reinforced bituminous membranes provide the durability and performance needed for these critical applications.

3.1 Road Construction & Ka malama ana

Bituminous membranes are used in road construction to prevent water from infiltrating the road base (which causes potholes, māwae, and structural failure). They are also used in road resurfacing to bond new asphalt to old. Manaʻo kikoʻī:

• Kaumaha: 200–250gsm
• Laulā: 400knm (to cover road lanes in one pass)
• Na Waiwai Ki: Ka ikaika tensile kiʻekiʻe (≥500 N/5cm MD) and fatigue resistance (≥85% strength retention after 10,000 nā pōʻaiapuni)

Nā pōmaikaʻi:

• Base Protection: Prevents water from reaching the road base, extending road life by 5–10 years.
• Stress Distribution: Absorbs and distributes traffic loads, reducing cracking in the asphalt surface.
• Kū'ē wela: Withstands the high temperatures of hot asphalt during resurfacing (up to 180°C) without shrinking.

Real-World Example: A highway department in Brazil used our 250gsm fabric-reinforced membranes in the construction of a 100km highway in the Amazon region (exposed to heavy rain and high humidity). Ma hope 3 makahiki, the highway showed 70% fewer potholes than similar roads built without the membrane, hoopakele ana $2 million in annual maintenance costs.

3.2 Tunnel Liners

Tunnels require waterproof membranes to protect against groundwater infiltration, which can damage electrical systems, weaken concrete structures, and create safety hazards. Our fabric-reinforced membranes are designed to withstand the high water pressure and constant vibration of tunnel environments. Manaʻo kikoʻī:

• Kaumaha: 200–250gsm
• Laulā: 400knm
• Nā mea hoʻohui: UV hoʻopaʻa (for tunnels with limited ventilation) and chemical-resistant finish (to withstand groundwater contaminants)

Nā pōmaikaʻi:

• Water Pressure Resistance: Withstands hydrostatic pressure up to 10 pā (equivalent to groundwater 100m below the surface), ka pale ʻana i ka leak.
• Kū'ē Kū'ē: Fatigue strength ensures the membrane remains intact despite constant vibration from trains or traffic.
• Hoʻokomo maʻalahi: Wide width reduces seams, which are vulnerable to water pressure in tunnels.

Real-World Example: A tunnel construction company in Switzerland used our 220gsm fabric-reinforced membranes in a 5km railway tunnel in the Alps (where groundwater pressure reaches 8 pā). Ma hope 2 makahiki o ka hana, the tunnel showed zero water infiltration — a first for tunnels in that region, which typically require annual waterproofing repairs.

3.3 Laina Laina

Landfills require multi-layer liners to contain waste and prevent leachate (contaminated water) from seeping into soil and groundwater. Bituminous membranes reinforced with our fabric form a critical part of this barrier system. Manaʻo kikoʻī:

• Kaumaha: 250gsm
• Laulā: 400knm
• Na Waiwai Ki: Kūleʻa kimemika (to leachate contaminants) a me ke kuʻe ʻana o ka puncture (to protect against sharp waste materials)

Nā pōmaikaʻi:

• Contamination Prevention: Resists degradation from leachate (which contains acids, metala kaumaha, and organic compounds), ensuring long-term containment.
• Puncture Protection: High puncture resistance (180 N) prevents damage from sharp objects in the waste (e.g., metal scraps, aniani).
• Ka lōʻihi: Service life of 30+ makahiki, matching the design life of modern landfills.

Real-World Example: A waste management company in Germany used our 250gsm fabric-reinforced membranes in a new landfill liner system. Ma hope 5 makahiki, testing showed the membrane had retained 95% o kona ikaika kumu, with no signs of chemical degradation — ensuring the landfill meets EU environmental regulations for leachate containment.

4. Bridge & Infrastructure Protection

Bridges, viaducts, and other infrastructure elements are exposed to harsh conditions: ua, snow, de-icing salts, and heavy traffic. Bituminous membranes reinforced with our fabric protect these structures from moisture damage, which can lead to corrosion of steel reinforcements and concrete deterioration.

4.1 Bridge Decks

Bridge decks require waterproof membranes to prevent water (and de-icing salts) from penetrating to the steel reinforcement below. Manaʻo kikoʻī:

• Kaumaha: 150–200gsm
• Laulā: 400knm
• Na Waiwai Ki: Salt resistance (to withstand de-icing chemicals) and adhesion strength (to bond with concrete and asphalt overlays)

Nā pōmaikaʻi:

• Corrosion Prevention: Blocks water and de-icing salts from reaching steel reinforcements, extending bridge life by 10–15 years.
• Overlay Bonding: High asphalt absorption ensures strong bonding with the asphalt overlay, preventing delamination under traffic loads.
• Hoʻololi: Accommodates minor bridge movements (from temperature changes or traffic) me ka pohā ole.

Real-World Example: A transportation authority in the U.S. used our 180gsm fabric-reinforced membranes on 10 highway bridges in the Northeast (where de-icing salts are heavily used). Ma hope 7 makahiki, bridge inspections found 80% less corrosion in the steel reinforcements compared to bridges without the membrane, reducing projected maintenance costs by $5 miliona.

4.2 Viaducts & Retaining Walls

Viaducts (elevated roadways) and retaining walls are prone to water infiltration from rain and groundwater, which can weaken their structural integrity. Our fabric-reinforced membranes provide a reliable waterproof barrier. Manaʻo kikoʻī:

• Kaumaha: 150–200gsm
• Laulā: 300–400cm
• Key Property: Size stability (to resist shrinkage/expansion in outdoor conditions)

Nā pōmaikaʻi:

• Structural Protection: Prevents water from seeping into concrete, reducing the risk of cracks and spalling.
• Hoʻokomo maʻalahi: Wide width allows for quick coverage of large surfaces (e.g., retaining walls up to 4m tall).
• Kūleʻa i ka lewa: UV stabilizer ensures the membrane remains intact even when exposed to direct sunlight (common in viaducts).

Real-World Example: A construction company in Spain used our 160gsm fabric-reinforced membranes on a 2km viaduct near Barcelona. The membrane’s size stability ensured it remained tight against the concrete structure through extreme temperature fluctuations (-5°C to 40°C), with no signs of wrinkling or delamination after 4 makahiki.

Hōʻoia maikaʻi: Ensuring Consistency & hana

A me WINIW, quality is embedded in every stage of production — from raw material selection to final inspection. Our Nonwoven Spunbond Polyester Fabric for Bituminous Membranes undergoes rigorous testing to ensure it meets or exceeds industry standards, providing manufacturers with a reliable material they can trust.

1. Ho'āʻo Mea Maka

We source only high-grade PET chips from certified suppliers (ISO 9001 a me ISO 14001 hooiaio). Each batch of PET chips undergoes the following tests before production:

• Helu Hehe (MFI): Tested per ASTM D1238 to ensure it falls within the 25–35 g/10min range — critical for consistent filament extrusion.
• Māmā: Measured using a Karl Fischer titrator to ensure it is <0.02% - ka pale ʻana i ka hoʻokumu ʻana o ka ʻōpū i ka wā extrusion.
• Impurity Analysis: A laser particle counter checks for contaminants (e.g., lepo, metal particles) e hōʻoiaʻiʻo <1 particle >50μm per 100g of chips — preventing defects in the final fabric.
• Tensile Strength of Virgin Filaments: A sample of filaments is extruded from each batch of chips and tested for tensile strength (≥3.5 cN/denier) — ensuring the raw material can form strong filaments.

Any batch of PET chips that fails these tests is rejected, preventing quality issues downstream.

2. In-Line Process Monitoring

Our production lines are equipped with state-of-the-art sensors and cameras that monitor key parameters in real time (1000+ data points per minute):

• Weight Uniformity: A beta-ray gauge measures fabric weight every 1cm along the width, ensuring ±3gsm consistency. If variation exceeds this, the system automatically adjusts the filament extrusion rate.
• mānoanoa: A laser thickness gauge checks the fabric’s thickness (0.3–0.8mm, ma muli o ke kaumaha) with a tolerance of ±0.05mm — critical for uniform asphalt absorption.
• Ikaika U'i: A miniaturized tensile tester built into the production line takes 10 samples per hour, ensuring MD/CD strength meets specifications (≥300 N/5cm for 100gsm fabric).
• Surface Defects: A 4K camera scans the fabric surface for defects (puka, nā kiko lahilahi, nā ʻāpana haole) as small as 0.5mm. Defective sections are automatically marked and removed during winding.

This real-time monitoring ensures that quality issues are identified and corrected immediately, reducing waste and ensuring consistency across the entire production run.

3. Laboratory Testing of Finished Products

Hoʻoholo: We recommended our 150gsm fabric with tight weight control (±3gsm) and enhanced asphalt absorption. We provided 50m samples for testing, and our technical team assisted in optimizing their coating process。
Nā hualoaʻa:

• Hoʻokuʻu ʻia ka ʻōpala hana mai 12% i 7.8% — saving €1.2 million annually.
• Delamination complaints in hot climates (e.g., Southern Europe) decreased by 90%.
• Their membrane passed EN 13956 (European standard for roofing membranes) with the highest rating, allowing them to enter new markets.

Kuhikuhi: “WINIW’s fabric consistency has transformed our production. The reduced waste and improved membrane performance have given us a competitive edge in Europe and beyond.” – Production Manager

Success Story 2: Asian Civil Engineering Firm Extends Road Life by 10 Years

Customer: A large civil engineering company in China, responsible for building and maintaining 5,000km of highways.
Paʻakikī: Roads built with conventional membranes required major repairs every 5–7 years due to water infiltration and base degradation. This caused traffic disruptions and high maintenance costs.
Hoʻoholo: We supplied our 250gsm fabric-reinforced bituminous membranes for a 200km highway section. The fabric’s high tensile strength and puncture resistance were designed to withstand heavy truck traffic and prevent water infiltration.
Nā hualoaʻa:

• Ma hope 8 makahiki, the highway section shows only minor cracks (vs. major potholes in adjacent sections built with conventional membranes).
• Maintenance costs reduced by 60% (from $500,000/km to $200,000/km over 8 makahiki).
• The company has specified WINIW’s fabric for all new highway projects,Projected savings are $50 million over 10 makahiki.

Success Story 3: North American Basement Waterproofing Company Boosts Customer Satisfaction

Customer: A basement waterproofing contractor in the U.S., serving 10,000+ homes annually.
Paʻakikī: Their previous membrane (reinforced with a polypropylene nonwoven) had a 15% failure rate within 2 makahiki, leading to costly callbacks and poor customer reviews.
Hoʻoholo: They switched to our 140gsm fabric-reinforced membrane, which offers better moisture resistance and size stability. We provided training for their installation team on proper application techniques.
Nā hualoaʻa:

• Membrane failure rate dropped to 2% — reducing callback costs by $800,000 makahiki.
• Customer satisfaction scores increased from 75% i 95%.
• The company expanded its service area, using their “leak-free guarantee” (backed by WINIW’s fabric) as a marketing tool.
