Cotton: good warmth retention; Sweat absorption; Soft and comfortable, very suitable for some people with sensitive skin. The disadvantage is that it is easy to wash and shrink.
Nylon: It has high strength and wear resistance, but the comfort is slightly insufficient because the moisture absorption rate is between -5%.
Lycra: Generally, it is not used alone, and a small amount is mixed into the fabric. This kind of fiber has both rubber properties and fiber properties, and is widely used to make elastic woven fabrics.
Acrylic fiber: It is the trade name of polyacrylonitrile fiber in China. Its elasticity is better, second only to polyester, and about 2 times higher than nylon. It has good shape retention. Acrylic fiber products have good bulkiness, good warmth retention, soft feel, good weather resistance, mildew and moth resistance.
Viscose fiber (wood pulp fiber, modal): The moisture content of viscose fiber is most in line with the physiological requirements of human skin, and it is smooth, cool, breathable, antistatic and brightly dyed. Viscose fiber has the essence of cotton and the quality of silk. It is an authentic ecological fiber, which comes from nature and is superior to nature.
Polyester: It is the trade name of polyester fiber in China. Polyester has good elasticity, stable size, durable pleating, easy washing and quick drying, and is not easy to wrinkle, mildew and moth. The disadvantage is that the friction coefficient is large and it is easy to generate static electricity, and the fabric is easy to stick to dust and get dirty.
Nowadays, with the development of textile materials and technology, underwear materials are mostly blended. Combining the advantages of various materials, the common ones are:
1: pure cotton (breathable, soft and comfortable, but extremely elastic, there are few such pure cotton fabrics on the market).
2. Pure cotton+spandex (this kind of fabric is the mainstream product in the market, including CK and D& which are popular now; G, DuDu, GMW and other styles.
This kind of fabric combines the softness of cotton and the elasticity of spandex, and is generally blended according to the ratio of 95% cotton +5% spandex)
3. Pure cotton+modal (excellent breathability and good elasticity, but because of the high cost of materials, the fabrics of this kind of underwear are generally light and soft). 4. Ice silk (mainly spandex, with poor air permeability, but silky to the touch, with the feeling of swimming trunks and good gloss)
5: Bamboo fiber, carbon fiber, soybean fiber (first of all, the efficacy of this material is affirmed, as many sellers say, but how much material is contained in those underwear is unknown)
