The difference between the fabric of clothing

Cotton:

    (1) hygroscopicity: cotton fiber has good hygroscopicity. Under normal circumstances, fiber can absorb water in the atmosphere around it, and its moisture content is 8-10%, so it contacts people's skin and makes people feel soft and not stiff. If cotton cloth humidity increases, the surrounding temperature is higher, the water component contained in the fiber will all evaporate dispersed, so that the fabric maintains a state of water balance, so that people feel comfortable.

    (2) the moisturizing effect: as the cotton fiber is a poor conductor of heat and electricity, heat conduction coefficient is extremely low, and because of the cotton fiber porous, high elasticity, between fiber can accumulate a large amount of air, the air is a poor conductor of heat and electricity, so the cotton fiber textiles have good moisturizing effect, pure cotton fabric dress makes people feel warm.

    (3) Heat resistance: cotton fabric heat resistance is good, below 110℃, will only cause moisture evaporation on the fabric, will not damage the fiber, so cotton fabric at room temperature, wearing, washing printing and dyeing have no effect on the fabric, thus improving the cotton fabric washable wear performance.

    (4) alkali resistance: cotton fiber resistance to alkali is large, cotton fiber in alkali solution, fiber does not damage phenomenon, the performance is conducive to taking the pollution of washing, disinfection in addition to impurities, but also on cotton textiles dyeing, printing and all kinds of processing, to produce more new varieties of cotton. (5) Hygiene: cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances and nitrogen and pectin. Pure cotton fabric has been inspected and practiced in many ways.

It has no stimulation or negative effect on skin contact. Wearing it for a long time is beneficial to human body and has good health performance.

    1. Easy to wrinkle, and wrinkle after more difficult to smooth.

    2. Easy to shrink, the shrinkage rate of cotton clothing is 2% to 5%, after special processing, or washing water treatment exception.

    3. Easy to deform. Cotton clothes are easy to deform, especially summer clothes, because the fabric is thinner.

    4. Easy to stick hair, difficult to remove completely. Polyester one. High strength. The strength of short fiber is 2.6 ~ 5.7cN/dtex, and that of high strength fiber is 5.6 ~ 8.0cN/dtex. Because of its low hygroscopicity, its wet strength is basically the same as dry strength. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber. 2. Good elasticity. Elastic close to wool, when elongation 5 ~ 6%, almost full recovery. Wrinkle resistance over other fibers, that is, the fabric does not wrinkle, good dimensional stability. The elastic modulus is 22 ~ 141cN/dtex, 2 ~ 3 times higher than nylon. 3. The heat-resistant polyester is made by melt spinning, and the formed fiber can be melted by heating again. It belongs to thermoplastic fiber. The melting point of polyester is relatively high, and the specific heat air and thermal conductivity are small, so the heat resistance and thermal insulation of polyester fiber are higher. It's the best of all synthetic fibers. 4. Polyester has a smooth surface and tightly packed molecules.

    5. Good wear resistance. Wear resistance next to the best wear resistance of nylon, than other natural fibers and synthetic fibers.
