How To Identify The Classification Of Pure Cotton Woven Fabrics And Cotton Woven Fabrics

Pure cotton woven fabric: cotton is used as raw material and woven by warp and weft yarn.

1. Cotton fabric is divided into:

(1) natural white cloth: plain cloth, fine cloth, coarse cloth, canvas, twill gray cloth, primary color cloth.

Colour cloth: there are vulcanized blue cloth, vulcanized ink cloth, shiilin blue cloth, Shilin grey cloth, color poplin, all kinds of khaji, different colors.

3. Cloth: a variety of colors and patterns on printing and dyeing.

For example, plain printed cloth, Printed Twill, printed Serge and printed tribute.

(4) yarn dyed fabric: it is a fabric that is dyed by yarn or thread first and then woven on the machine, such as cloth, sheet cloth, flannelette, thread, decorative cloth, etc.

2, the characteristics of pure cotton fabric:

1. Hygroscopicity: cotton fiber has good hygroscopicity. Under normal conditions, fiber can absorb moisture into the surrounding atmosphere. 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 is increased and the ambient temperature is higher, the water content in the fiber will evaporate completely, so that the fabric can maintain the water balance state and make people feel comfortable.

Moisturizing property: because cotton fiber is a poor conductor of heat and electricity, its thermal conductivity is very low, and because of its porous nature and high elasticity, it can store a lot of air between the fibers, and the air is also a poor conductor of heat and electricity. Therefore, pure cotton fiber textile has good moisture retention, and it feels warm in pure cotton fabric clothing.

Heat resistance: pure cotton fabric has good heat resistance, and it will only cause moisture evaporation on the fabric at less than 110 degrees Celsius. It will not damage the fiber. So pure cotton fabric can be used at normal temperature, washing, printing and dyeing.

Alkali resistance: cotton fiber has greater resistance to alkali, and cotton fibers do not damage in alkali solution. This property is beneficial to washing and disinfection after taking the medicine, and can also dye, print and process all cotton textiles, so as to produce more new cotton varieties.

Hygiene: cotton fiber is a natural fiber, its main components are cellulose, and a small amount of waxy substances and nitrogenous substances and pectin.

The cotton fabric has been tested and tested in many ways. There is no stimulation and no negative effect on the contact between the fabric and the skin. Long wearing is beneficial to the human body and has good hygienic performance.

How to identify fabrics: (hand feeling)

Fabric handle is an important part of people's identification of fabric's quality and quality.

Concretely speaking, the psychological reaction of touching the fabric with hands is different due to the different varieties of fabrics, and the quality of the fabrics varies greatly.

The following aspects:

(1) whether the body bones of the fabric are smooth and rough; (2) the smooth and rough surface of the fabric; (3) the softness and hardness of the fabric; (4) the thickness and thickness of the fabric; (5) the cold and warm fabric; and the fabric has a feeling of irritation and no stimulation to the skin.

For example, the hand feels the cool feeling of silk fabrics; the pure wool fabric has a warm feeling; the handle is thin and smooth, and the cotton fabrics are mostly made of high count yarns, and the coarse ones are mostly low count yarn fabrics.

In addition, people can borrow the action of assisting, stretching with hand, grasping grain and other movements, and then through the observation of the eye and the feeling of the hand, we can judge the elasticity, strength, wrinkle resistance and fiber type of the fabric.

But in general, hand feeling is the most important way to buy Fabrics and clothing.

Fabric three elements

1) plain weave: fabric formed by the interweaving of warp and weft in one up.

The molecule denominator represents the weft organization point through the organization point.

2) twill: the fabric formed by the interweaving of warp and weft on two ends.

A fabric formed by weaving two warps and weft threads on two sides.
