TPU composite fabric

Basic knowledge of composite fabrics:

Composite fabrics in English are: “Lamination Fabric” and “Soft Shell Fabric”. TPU composite fabrics and PTFE composite fabrics are made by bonding one or more layers of textile materials, non-woven materials and other functional materials. A new type of material. TPU composite fabrics and PTFE composite fabrics are divided into ordinary composite fabrics (made by bonding fabrics and linings with adhesives to improve the fabric texture, suitable for process simplification and large-scale production of clothing processing) and functional composite fabrics (composited The fabric has special functions such as waterproof, moisture permeable, radiation resistance, washing resistance, and wear resistance).

There are 6 internationally popular composite fabric technologies, namely hot sol powder dot coating composite fabric technology, hot sol pulp dot composite fabric technology, hot sol dusting composite fabric technology, hot sol double dot composite fabric technology, polyamine Fabrics compounded by grease spraying composite fabric technology and polyurethane roller coating composite fabric technology are a new type of TPU composite fabric and PTFE composite fabric developed by the market. In short, they are two fabrics compounded together. . In the past, the most common composite we had was the composite of suede fabric and wool. Nowadays, any fabric can be used to composite it together. Kunshan Yingjie Textile Import and Export Co., Ltd.–believes that composite fabrics will shine in the future fabric market and clothing market.

Composite fabric, also called waterproof and breathable fabric, is a new type of textile fabric. It is made of polymer waterproof and breathable material (PTFE film or TPU film) plus cloth composite fabric. The main functions of waterproof and breathable fabrics are: waterproof, moisture-permeable, breathable, insulating, windproof, and warm. In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, from a quality point of view, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof and breathable fabrics not only enhance the air-tightness and water-tightness of the fabric, but also have unique breathable properties that can quickly discharge water vapor inside the structure, avoid mold breeding in the structure, and keep the human body always dry. It perfectly solves the problem of breathability, windproof, waterproof, It is a new type of fabric that is healthy and environmentally friendly.

Features of three-layer TPU composite fabric and three-layer PTFE composite fabric:

1) High-performance surface fabric is durable windproof, waterproof and has excellent antistatic properties;

2) TPU, TPFE, PU, ​​PEVA, PE transfer coating and other films ensure good breathability and moisture permeability;

3) The lining fabric has the dual functions of moisture wicking and antibacterial and deodorizing;

4) In the layer structure, the high-performance surface fabric is closely combined with the film, and the lining fabric is loose and flexible;

5) In the three-layer structure, the film is sandwiched between the surface fabric and the lining fabric;

Function of composite fabrics:

This fabric is highly windproof, highly waterproof, moisture-permeable, warm, aging-resistant, freeze-resistant, and abrasion-resistant. and other functions to keep your body dry and comfortable for a long time. TPU composite fabrics and PTFE composite fabric products have the advantages of soft hand feel, high peel strength, washing resistance, hydrolysis resistance, low temperature resistance, stable waterproof and breathable physical properties, etc.

Application scope of composite fabrics:

Mainly used for jacket fabrics, ski clothing fabrics, outdoor casual clothing fabrics, jacket fabrics, sports and leisure clothing fabrics, special clothing fabrics, medical and health material fabrics, national defense and military industry fabrics, ski clothing fabrics, mountaineering clothing fabrics, Cold-proof clothing fabrics, special clothing fabrics, high-end outdoor clothing fabrics, sporting goods, military clothing, aerospace, medical fields, fire protection, field uniforms, fire protection, military special clothing; protective equipment, military tents, sleeping bags and postal bags ; Sports clothing for mountaineering, skiing, golf and other sports; Materials for shoes and hats, bags, blackout curtains, anti-UV umbrella cloth; Rainproof and breathable ponchos, casual windbreakers

Three-layer TPU composite fabric and three-layer PTFE composite fabric, called in English: Soft Shell Fabric, also known as: Lamination Fabric, Waterproof Breathable Fabric, are a high-end functional fabric with windproof warmth, abrasion resistance, high Waterproof, highly breathable and moisture permeable, acid and alkali resistant, etc. In particular, TPU and PTFE composite fabrics with waterproof and moisture-permeable functions have many advantages such as softer feel, strong peeling fastness, and tear resistance than ordinary waterproof and breathable fabrics.

Detailed introduction to the evaporation resistance of composite fabrics:

When the evaporation resistance of TPU composite fabrics and PTFE composite fabrics produced by Kunshan Yingjie Textile Import and Export Co., Ltd. is less than 6m2Pa/W, it is called “extremely breathable” and is comfortable to wear at high exercise levels; the evaporation resistance of three-layer composite fabrics When the evaporation resistance of the three-layer composite fabric is 13-20m2Pa/W, it is called “very breathable”. It is generally comfortable to wear at high exercise levels, but comfortable to wear at normal exercise levels. For “breathability” in high movement waterIt is uncomfortable at ordinary times, but comfortable at normal exercise levels; when the evaporation resistance of the three-layer composite fabric is 20-30 m2Pa/W, it is called “low breathability”. It is very uncomfortable to wear at high exercise levels, but at low exercise levels Generally comfortable; when the evaporation resistance of the three-layer composite fabric is higher than 30m2Pa/W, it is called “airtight” and is uncomfortable to wear at all exercise levels.

Four-way elastic composite fabric is often called Soft Shell Fabric. The four-sided elastic is mainly 75D (for women’s clothing) and 100D (for men’s clothing), and the polar fleece is mainly 75D/72F and 100D/144F. Generally, polar fleece composite fabrics are the main ones, that is, the fabric is four-sided elastic fabric, and the base fabric is polar fleece, which is the TPU polar fleece composite fabric we often see. It can have many styles such as plain weave, twill weave, plaid, etc. Because it is waterproof, breathable, windproof and warm, its use is no longer limited to ordinary outdoor sportswear. Many large foreign companies use it as employee work clothes, outdoor mountaineering clothing, etc.

Chemical fiber woven polar fleece composite fabric TPU Tricot (polyester warp knitted mesh fabric). Woven polar fleece composite fabrics mainly include pongee, taslan, oxford cloth, peach skin, nylon, etc. Ordinary ones such as 228T Taslon can be used as the main fabric of jackets; nylon camouflage printed fabrics can be used as military clothing; fluorescent fabrics can be used as police uniforms and other work clothes;

Kunshan Yingjie Textile Import and Export Co., Ltd. adopts a special composite process to maintain the waterproof, moisture permeable, windproof, warm-keeping and other properties of PTFE and TPU membranes to the greatest extent. The composite products have soft hand feel, high peel strength, and water resistance. , low temperature resistance, stable quality and other characteristics. It can quickly discharge human sweat, integrates high waterproof, windproof and warmth retention properties, making it comfortable to wear and beautiful.
