Composite film introduction PTFE composite film

Polytetrafluoroethylene (PTFE) composite fabric is a high-functional fabric that integrates waterproof, moisture-permeable, wind-proof and other properties. The microporous PTFE film is susceptible to dust and sweat contamination, clogging micropores, and poor deformation recovery. It is the first generation of Core-tex waterproof and moisture permeable fabric.

The second-generation Core-tex waterproof and moisture-permeable fabric is coated with a hydrophilic and oil-repellent polyurethane (PU) waterproof and moisture-permeable coating on one side of the water-repellent PTFE membrane. This hydrophilic layer prevents contamination of the microporous membrane and maintains the long-term waterproof and moisture permeability of the Core-tex fabric. The disadvantage is that the moisture permeability of the fabric is degraded.

PTFE composite film can be widely used in combination with various types of fabrics:

Winter clothing: such as winter clothes, polar protective clothing, sand touch protective clothing, bad weather protective clothing.

Special protective clothing fabrics: fire suits, anti-biochemical suits, water-immersed work clothes, cold-resistant anti-dipping suits, pesticide protective clothing, acid-base protective clothing, surgical gowns, etc.

Sportswear: mountaineering suits, running suits, golf wear, ski wear, fishing suits, hunting suits, etc.

Shoes, hats, gloves, sleeping bags, tents, rain gear, etc.

PU composite film

The TPU composite film, that is, the principle of moisture permeability of the thermoplastic hydrophilic polyurethane film, firstly, the hydrophilic segment absorbs the moisture emitted by the body temperature, and the moisture is diffused from the inside to the outer layer by the movement of the hydrophilic segment. (ie, from high pressure to low pressure), then the moisture is evaporated into the outside atmosphere. That is to say, by using the special molecular structure of the thermoplastic polyurethane, the water molecules are transferred one by one by the hydrophilic group to achieve the purpose of high moisture permeability. Secondly, because it has no pores on the surface, its rain and snow can not penetrate, and the water pressure can reach 9.8×104 Pa (10000mm H2O) or more. TPU can be washed, low temperature up to -30 ° C, soft texture, is a better price and is not high (compared with PTFE film) laminated film material.

Product waiting: green, excellent breathable and moisture permeable; absolutely waterproof, anti-blood, antibacterial; wind and cold resistant, anti-velvet, smooth; durable, super water-repellent finishing; easy to decontaminate, can be washed normally.

Scope of application: Field military uniforms, firefighting, military special clothing; protective articles, military tents, sleeping bags and postal bags; sportswear for hiking, skiing, golf, etc.; shoes and hats, bags, blackout curtains, UV umbrellas; Rainproof, breathable poncho, casual windbreaker; medical insurance supplies.

Suitable for knitting, weaving, non-woven fabrics and other different fabrics. The most popular TPU composite fabrics on the market today are:

Four-sided bomb + TPU + fleece, is often called SoftShell. The four-sided bombs are mainly 75D (for women's wear) and 100D (for men's wear), and the fleece is mainly for 75D/72F and 100D/144F. There are many styles such as plain, twill, and plaid. Because of its waterproof, moisture-permeable, wind-proof, and warmth, the scope of use is now not limited to ordinary outdoor sportswear, and many large foreign companies use it as an employee's overalls.

Chemical fiber woven fabric + TPU + Tricot (polyester warp knitted mesh fabric). Woven fabrics are mainly chryso, taslon, oxford, jeanette, and nylon. Ordinary such as 228T Taslon can be used as the main fabric of the jacket; while nylon camouflage printed fabric can be used for military clothing; fluorescent fabrics can be used for police uniforms and other tooling;

Microporous PU composite film with good gas permeability.

Hydrophilic and microporous PU composite membranes combine the advantages of both

The composite membrane of PTFE combined with TPU can overcome some weaknesses of PTFE.

Various extension products of PTFE composite film, TPU composite film and PU composite film, colored, colorless, color film, etc.
