Definition: Shiyi cotton woven fabrics of cotton as raw material, through the loom, the warp and weft interwoven vertical and horizontal ups and downs with each other textiles.
2, cotton fabric is divided into:
(1) Natural white: common cloth, fine cloth, coarse cloth, canvas, twill fabric, color cloth. (2) color cloth: blue cloth with curing, curing ink cloth, Shihlin blue cloth, Shihlin gray cloth, color poplin, colored card grumble, colored Chinese do. (3) fabric: is printing on a variety of fabric colors and patterns. Such as: plain cloth, twill fabric printing, printing serge, printed satin. (4) dyed: it is the first line after dyeing or yarn, woven into the machine after the cloth such as bar gingham, linen cloth, flannel, line on the road, fabrics and so on.
3, pure cotton features:
① moisture absorption: Cotton fiber has good moisture absorption, in normal circumstances, the fibers can absorb the moisture in the atmosphere around, and its moisture content of 8-10%, so it contacts the skin, soft and makes people feel not rigid. If the cotton humidity increases, the higher the ambient temperature, fiber volume will contain all the evaporation of the water dispersed, so that the fabric to maintain the water balance, people feel comfortable.
② moisture: Because cotton fiber is a poor conductor of heat and electricity, thermal conductivity is very low, because of its porous nature of cotton fibers, the advantages of high flexibility, can accumulate large amounts of air between the fibers, the air is a poor conductor of heat and electricity Therefore, cotton fiber textile has good moisture retention, wearing pure cotton clothing make people feel warm.
③ Heat resistance: pure cotton fabric can be a good heat, at temperatures below 110 ℃, evaporation will cause the fabric will not damage the fiber, so the cotton fabric at room temperature, wear use, washing and dyeing of fabrics have no effect , thus improving the durability of pure cotton washable wearability.
④ alkali resistance: cotton fiber for greater resistance to alkali, alkaline solution in the cotton fiber, the fiber damage phenomenon does not occur, after taking the performance benefit of pollution washing, disinfection in addition to impurities, but can also on cotton textiles dyeing, printing and processing of a variety of processes to generate more new varieties of cotton.
⑤ Health of: Cotton fiber is a natural fiber, the main ingredient is cellulose, a small amount of waxy material and nitrogen material with pectin. Cotton fabric by the various inspection and practice, fabric and skin contact without any stimulation, no negative effect on the human body hurt to wear a long time, in good health.
How to Identify fabric: (hand method)
Fabric is that people feel the quality of fabric used to identify an important quality. Specifically, the feeling of fabric touching the psychological reaction, due to the different varieties of fabric, quality, rates will also vary, fabric feel the effect, it is quite different. Feel in the following areas:
① fabric is crisp and bone body relaxation; ② smooth and rough surface of the fabric; ③ fabric soft and hard; ④ thin and thick fabrics; ⑤ cold and warm fabric; ⑥ fabric for skin irritation and no less excited thorn feeling. For example: real silk spinning products are feeling the hand on the feeling of cold; pure wool fabric with warm feeling; feel thin and smooth Dacron cotton are mostly made of high-count yarn copy; feel rough, mostly low-yarn fabric.
In addition, people can use the role of power, hand stretching, grasping patterns and other activities, and through the eye of observation, hand feel, you can determine the fabric of resilience, strength, crease resistance and fiber types and so on. But in general, feel the fabrics and clothing to buy the most important means.
Organizational fabrics Mihara
1) plain weave: the warp and weft to form a last look of woven fabric. Molecules expressed by the organization which point, the denominator represents the organization point of latitude. 2) Twill: warp and weft to two on the look of woven fabric formation. Warp and weft to two on two intertwined under the fabric
