Basic knowledge of four-sided elastic TPU composite fabrics and PTFE composite fabrics
The English name of composite fabric is: "laminationfabric" and "softshellfabric". TPU composite fabric and ptfe composite fabric are a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. TPU composite fabrics and PTFE composite fabrics are divided into ordinary composite fabrics (made by bonding fabrics and linings with adhesives to improve the texture of the fabric, 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 six 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 two-point composite fabric technology, and polyurethane spray composite fabric technology. Fabric technology, polyurethane roller coating composite fabric technology composite fabric is a new type of TPU composite fabric and PTFE composite fabric developed by the market. In short, it is a fabric composed of two fabrics combined 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. Fiber Technology We believe 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 four-sided elastic 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) Various films such as tpu, tpfe, pu, peva, pe transfer coating ensure good breathability and moisture permeability;
3) The lining fabric has the dual functions of moisture wicking, 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;
The functions of three-layer TPU composite fabric and three-layer PTFE composite fabric:
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 feel, high peel strength, washing resistance, hydrolysis resistance, low temperature resistance, stable waterproof and breathable physical properties, etc.
The scope of application of three-layer TPU composite fabric and three-layer PTFE composite fabric:
Mainly used for jacket fabrics, ski clothing fabrics, outdoor casual clothing fabrics, jacket fabrics, sports and leisure clothing fabrics, special clothing fabrics, medical and sanitary 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; mountaineering, Clothing for 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: softshellfabric, also known as: laminationfabric, waterproofbreathablefabric, are a high-end functional fabric with windproof and warm insulation, friction resistance, high waterproof, high breathability and moisture permeability. Anti-acid and alkali effects. 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 TPU composite fabrics and PTFE composite fabrics:
When the evaporation resistance of the TPU composite fabrics and PTFE composite fabrics mainly produced by Fiber Technology is less than 6m2pa/w, it is called "extremely breathable" and is comfortable to wear at high exercise levels; when the evaporation resistance of the three-layer composite fabric is 6-13m2pa/w, It is called "very breathable", and the wearing comfort is average at high exercise levels, but it is comfortable to wear at normal exercise levels; when the evaporation resistance of the three-layer composite fabric is 13-20m2pa/w, it is called "breathable", and it is comfortable to wear at high exercise levels. It is uncomfortable when horizontal, but comfortable at general exercise levels; when the evaporation resistance of the three-layer composite fabric is 20-30m2pa/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 "non-breathable" and is uncomfortable to wear at all exercise levels.
Four-way elastic composite fabric is often called softshell 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 tputricot (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 Taslan 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;
Adopting a special composite process, the waterproof, moisture-permeable, windproof, and warmth-keeping properties of PTFE and TPU membranes can be maintained to the greatest extent. The composite products have the characteristics of soft hand feel, high peel strength, water resistance, low temperature resistance, and stable quality. It can quickly discharge human sweat, integrates high waterproof, windproof and warmth retention properties, making it comfortable to wear and beautiful.
