Pure cotton fabrics are divided into:
① Substantial white cloth: general cloth surface, muslin, coarse cloth, canvas, twill grey cloth, primary color cloth.
② Color cloth: There are vulcanized blue cloth, vulcanized ink cloth, shilin blue cloth, shilin gray cloth, colored poplin, various colors of kaji, and various colors of flowers.
③ Flower cloth: It is a cloth that is printed and dyed with various colors and patterns. Such as: plain pattern printed cloth, printed twill cloth, printed serge, printed straight tribute.
④ Yarn-dyed fabric: It is a fabric that dyes yarn or thread first, and then weaves it mechanically, such as grid cloth, quilt cloth, flannel cloth, tweed, decoration cloth, etc.
Features of pure cotton fabrics:
① Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere, and its moisture content is 8-10%, so it touches human skin and makes people feel soft and not rigid. If the humidity of the cotton cloth increases and the surrounding temperature is high, the weight of the water contained in the fiber will evaporate and dissipate, making the fabric connect and balance the situation, which is comfortable.
② Moisture retention: Because cotton fibers are poor conductors of heat and electricity, the thermal conductivity coefficient is extremely low, and because cotton fibers are porous and have high elasticity, a large amount of atmosphere can be accumulated between fibers, and the atmosphere is not good for heat and electricity. Therefore, pure cotton fiber textiles have good moisture retention, and wearing pure cotton fabric clothing makes people feel warm.
③ Heat resistance: Pure cotton fabrics have good heat resistance. When it is below 110 ° C, it will only cause the water on the fabric to evaporate and will not damage the fibers. Therefore, pure cotton fabrics have no effect on the fabrics at room temperature, such as wearing applications, washing, printing and dyeing. It has no effect on the washing, wearing and wearing function of pure cotton fabrics.
④ Alkali resistance: cotton fibers have greater resistance to alkali. When cotton fibers are in alkali solution, the fibers do not produce signs of damage. This function is conducive to washing stains after taking them, disinfecting and removing impurities, and at the same time, it can also be used for pure cotton textiles. Dyeing, printing and various technological processing to produce more new types of cotton weaving.
⑤ Wealthy quality: Cotton fiber is a natural fiber, and its main component is cellulose, and there are also small batches of waxy materials, nitrogen-containing substances and pectin. Pure cotton fabrics have been tested and practiced in many ways, and the fabric has no irritation and no negative use when it touches the skin. It is beneficial and harmless to the human body after long-term wear, and has good hygiene function.... Now there are many kinds of fabrics. How to determine the texture of the fabric? It is not difficult, only a few yarns are taken from the corners of the fabric and can be identified by burning... There is a strong smell of burning hair, the ashes are black and fluffy spherical, which is pure wool or silk fabric, while the wool is short fiber, and the silk is long fiber, which can be distinguished from the appearance.. There is a smell of burning hair, and there is a gray powder in the ashes, which is a wool-viscose blend fabric.. There is a smell of burning hair, and the ashes are firmer and spherical, which is a blend or cross fabric of wool and synthetic fibers.. There is neither a smell of burning hair nor a smell of burning paper, but the rest of the extra breath, the ashes are firm and spherical or block, and are synthetic fiber pure spinning or blended fabrics.
How to identify foreign fabric character signs?
Foreign countries have the same mark on the character of fabrics. Divided into:
(1) 100% Cotton.
(2) Full hair. 100% Wool.
(3) All polyester fiber. 100% Polyester (poly).
(4) Pure hair: Pure Wool.
