Characteristics of pure cotton fabric

① Hygroscopicity: cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere. Its moisture content is 8-10%, so it contacts people's skin and makes people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is high, all the water content in the fiber will evaporate and disperse, so that the fabric can maintain water balance and make people feel comfortable.

② Moisture retention: because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is very low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between fibers, and air is a poor conductor of heat and electricity, pure cotton fiber textiles have good moisture retention, and people feel warm wearing pure cotton fabrics and clothes.

③ Heat resistance: pure cotton fabric has good heat resistance. When the temperature is below 110 ℃, it will only cause moisture evaporation on the fabric and will not damage the fiber. Therefore, the wearing, washing, printing and dyeing of pure cotton fabric at room temperature have no impact on the fabric, which improves the washing, wearing and wearing performance of pure cotton fabric.

④ Alkali resistance: cotton fiber has great resistance to alkali. When cotton fiber is in alkali solution, the fiber will not be damaged. This performance is conducive to the washing, disinfection and impurity removal of pollution after taking. At the same time, it can also dye, print and process pure cotton textiles, so as to produce more new cotton varieties.

⑤ Hygiene: cotton fiber is a natural fiber. Its main component is cellulose, as well as a small amount of waxy substances, nitrogen-containing substances and pectin. The pure cotton fabric has been inspected and practiced in many aspects. The contact between the fabric and the skin has no stimulation and negative effect. It is beneficial and harmless to the human body after long wearing, and the sanitary performance is good.

In view of the causes of wrinkle of pure cotton fabric, the first process route of non ironing finishing of pure cotton fabric is the pre baking method, that is, all processes such as fabric flat width dip rolling resin and flat width baking are completed by the printing and dyeing factory. This is a traditional process route. Its deficiency is that it brings certain difficulty to garment processing, and it is difficult to give clothing some pleats and garment shapes, so it is only suitable for finishing and processing of cloth; the second is to adopt the now widely popular post baking method Baking method can be divided into grey cloth impregnation and garment impregnation according to different ways of impregnation and rolling resin. The former is that pure cotton fabric is soaked in resin and dried in the printing and dyeing factory, and the resin crosslinking reaction is completed only after the resin is left in the garment sewing and put into the baking oven; the latter is dried and baked after soaking and finishing solution or spraying. After the clothing is baked, the cross-linked resin will fix the folding and flat appearance of the clothing. After the clothing is worn and washed, the fiber trend is trying to return to the state of cross-linking, which is the so-called "form memory" function. After durable press finishing, the clothing has the characteristics of soft hand feeling and long folding? Using this method for non ironing finishing, the production can be flexibly and effectively controlled, and some special finishing (such as sand washing finishing) can be flexibly carried out before finishing, so as to achieve processing multiplicity and functional diversity, and greatly improve the grade and wearing comfort of clothing.
