Knowledge summary of current socks materials (Chapter 3)
1 nanometer is one billionth of a meter, which is equivalent to the length of 45 atoms arranged, and the thickness is equivalent to one tenth of a million of hair. Due to the characteristics of small size and large specific surface area, excellent compatibility when combined with other materials, and they can fully transfer and display their unique functions in compatible and identical materials.
Polyamide fiber, scientific name, is the general name for polyamide fiber produced in China. Internationally known as nylon. High strength, abrasion resistance and good resilience, it can be used in pure and blended fabrics for various clothing and knitwear. Strong and wearable, ranking first among all fibers. Its abrasion resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber. Therefore, its durability is excellent. The elasticity and elastic recovery of the nylon fabric are excellent, but it is easily deformed under a small external force, so the fabric is easily wrinkled during wearing. Poor ventilation and easy to generate static electricity. The hygroscopicity of nylon fabrics is a better variety among synthetic fiber fabrics. Therefore, clothing made of nylon is more comfortable to wear than polyester clothing, and has good resistance to moth and corrosion.
Polyester is an important variety of synthetic fibers and is the trade name of polyester fiber in China. It is a fiber-forming high polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials through esterification or transesterification and polycondensation— — Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. Polyester is very versatile, and is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent shape setting properties. After the polyester yarn or fabric is shaped, the flatness, fluffy shape or pleats, etc., after repeated washing in use, can still be unchanged for a long time.
It is a high-tech polyester amine fiber developed by DuPont. It has a soft touch, good air permeability, and is comfortable to wear. The fabric made of Tactel is fine, breathable, soft, comfortable and anti-wrinkle, keep clothing as new as possible.
When people exercise or do other activities, the body often produces sweat and moisture. Sweat makes you feel cold and uncomfortable when the weather is cold; sweat and moisture make people feel sultry and uncomfortable. DuPont's high-tech fiber COOLMAX quickly guides sweat and moisture away from the skin surface through the four-pipe fiber and spreads it in all directions, allowing sweat to evaporate faster and keep the skin dry and comfortable.
This fiber is also a new fiber launched by DuPont. It is a kind of hollow fiber produced by imitating the fluff of a polar bear. It is said that its insulation performance is particularly excellent. Each fiber contains more air, forming an air protection layer, which can prevent cold air from entering and can also discharge moisture. Keep the wearer's body warm, dry, comfortable and light. Thermolite fabrics have a drying rate about twice that of silk and cotton fabrics, making them suitable for mountaineering suits, ski shirts, sleeping bags, etc.
A natural insulating material that is comfortable, lightweight, but not as wearable as other materials. Sometimes it is used as a reliable perspiration material for socks.
The above is the content about 7 kinds of sock making materials that I talked about today. If you have any different opinions, please share together.
