1, moisture permeability: No matter which season is spring, summer, autumn and winter, it is definitely uncomfortable to wear air-tight and moisture-permeable clothing, because the air-tight and moisture-permeable fabric can't be released into the outside air because of the sweat discharged by the human body, which will not only make you feel stuffy, but also cause skin diseases such as eczema if the sweat stays on your skin, which is very unfavorable to human health. In this respect, natural fabrics such as silk, cotton, hemp and wool are definitely superior to chemical fiber fabrics such as polyester, acrylic and nylon, and also superior to regenerated fibers such as Tencel, ice silk, acetate fiber and cuprammonia fiber.

2, wind and warmth: wind and warmth are the most basic requirements for clothing, especially in cold winter conditions, a warm dress will feel particularly comfortable to wear. The warmth retention of clothing mainly depends on the static air quantity that can be fixed around the fabric. The more static air there is, the warmer the fabric will be. Among natural fabrics, cashmere and alpaca wool have the best warmth retention, because their fibers are hollow and light, which can absorb the surrounding air best, while wool's warmth retention is second only to cashmere and alpaca wool, among which mohair and merino wool have the best performance, while domestic wool is relatively poor. In addition, fur clothing has good wind resistance and warmth retention, among which mink is the best, while fox hair, rabbit hair and wool are relatively poor. Of course, the fur here refers to a kind of fur, but the warmth retention of composite fur such as sheep shearing or granular wool, which is popular in recent two years, is actually not good.

3, skin-friendly: no matter what fabric, if worn on the body, it is very uncomfortable and unfriendly to the skin. As far as skin friendliness is concerned, silk clothing is definitely the best. Mulberry silk is not only soft and smooth, but also rich in amino acids beneficial to human body. Cashmere and alpaca hair are also very skin-friendly, both of which are soft and have no irritation to the skin. Moreover, alpaca hair does not contain oil and generally does not dye, which is more conducive to human health. It can be said that cashmere or alpaca hair is the first choice for close-fitting sweaters in winter. Then cotton and some man-made regenerated fibers, mainly modal, Tencel, cuprammonia silk, acetate fiber, viscose fiber and so on. Although these fabrics are man-made fibers, they are quite skin-friendly compared with chemical fibers. Because marijuana is rough, its skin friendliness is generally not very good.

4, cool feeling: summer clothing pays great attention to the cool feeling of fabrics. In high temperature, wearing all-round clothes is like turning on the air conditioner. Among natural fabrics, hemp has the best coolness. Hemp is not only good in moisture absorption, but also very good in moisture permeability. It dries quickly, unlike cotton, and won't dry for a long time. Because it dries quickly, the evaporation of water will absorb heat to the human body, making people feel cool in hot summer. Next to hemp is silk, which is also very breathable. In addition, the moisture content of regenerated fibers such as viscose fiber is also very suitable for the needs of human body, so the cool feeling is also good. Of course, the coolness of clothing also depends on the permeability and design structure of the fabric. The better the fabric permeability, the more sand holes, the lower the fabric density, and the cooler it will be. The bigger the design of cuffs and hem, the stronger the blowing effect will be and the human body will feel cooler.
