1. Definition: Pure cotton woven fabric is made of cotton as raw material. Through the loom, the warp and weft yarns rise and fall with each other vertically and horizontally. Interwoven textiles.
2. Pure cotton textiles are divided into:
① Natural white cloth: ordinary cloth, fine cloth, coarse cloth, canvas, twill gray cloth, original color cloth.
②Colored cloth: There are vulcanized blue cloth, vulcanized ink cloth, Shilin blue cloth, Shilin gray cloth, colored poplin, various colors of khaki, and various colors of Chinese cloth. .
③Calico: It is cloth printed and dyed with various colors and patterns. Such as: plain printed fabric, printed twill, printed serge, printed Zhigong.
④Yarn-dyed fabric: It is a fabric made by dyeing yarn or thread first and then weaving it on a machine, such as checked cloth, sheet cloth, flannel cloth, etc. Threads, decorative fabrics, etc.
3. Characteristics of pure cotton fabrics:
① Moisture absorption Properties: Cotton qianwei has good hygroscopicity. Under normal circumstances, qianwei can absorb moisture from the surrounding atmosphere. Its moisture content is 8-10%, so when it contacts people’s skin, it makes people feel soft but not stiff. . If the humidity of the cotton cloth increases and the surrounding temperature is high, all the moisture contained in the fabric will evaporate and dissipate, keeping the fabric in a water balance state and making people feel comfortable.
②Moisture retention: Because cotton fabric is a poor conductor of heat and electricity, the thermal conductivity coefficient is extremely low, and because cotton fabric itself has the advantages of porosity and high elasticity, A large amount of air can accumulate between the fabrics, and air is a poor conductor of heat and electricity. Therefore, pure cotton fabrics have good moisture retention, and wearing pure cotton fabrics makes people feel warm.
③Heat resistance: Pure cotton fabric has good heat resistance. When it is below 110℃, it will only cause the water on the fabric to evaporate and will not damage the fabric. Therefore, pure cotton fabrics have no effect on the fabrics when worn, used, washed, printed and dyed at room temperature, thus improving the washability, durability and wearability of pure cotton fabrics.
④Alkali resistance: Cotton qianwei has greater resistance to alkali. Cotton qianwei will not be damaged in an alkali solution. This property is conducive to consumption. Afterwards, the pollution is washed, disinfected and impurities removed. At the same time, pure cotton textiles can be dyed, printed and processed in various processes to produce more new varieties of cotton fabrics.
⑤Hygiene: Cotton cotton is natural cotton, its main component is cotton, as well as a small amount of waxy substances, nitrogen-containing substances and pectin. Pure cotton textiles have been tested and practiced in many aspects. There is no irritation or negative effects when the fabric comes into contact with the skin. It is beneficial to the human body when worn for a long time and has good hygienic performance.
