The definition of cotton fiber

Cotton fiber is from fertilization of the ovule epidermal cells after elongation, thicken and become the seeds of fiber, different from general bast fibers. It is the main material of cellulose. Cellulose is a natural polymer compound, chemical structure type (C6H10O5) n. Normal mature cotton cellulose content is about 94%. Also contains a small amount of pentosan, wax, such as protein, fat, ash content, water soluble substances along. Because the cotton fiber has many excellent good economic characters, has become the main textile industry raw materials.

The performance of the cotton fiber:

Cotton fiber of high strength, good wrinkle resistance and stretchability is poor; Has good heat resistance, second only to the linen; Acid resistance, resistance to dilute alkali at room temperature. To dye with good affinity, dyed easily, chromatography is complete, the color is more bright-coloured.

The definition of the cotton fabric

The cotton fabric refers to cotton yarn or cotton and cotton type polyester blended yarn woven fabric.

The characteristics of the cotton fabric:

1. The hygroscopicity strong, shrinkage is bigger, about 4 ~ 10%.

2. Alkaline not acid. Cotton cloth of inorganic acid volatile, even very dilute sulfuric acid also can make the damage, but function weak organic acid, little damage. Cotton is alkali, general dilute alkali at room temperature for cotton don't happen but after alkali effect, strength of cotton fabric will decline. Often use 20% caustic soda processing cotton, "mercerized cotton can be obtained.

3. The light resistance, heat resistance. In cotton will be slow in the sunlight and atmospheric oxidation, decreased strength. High temperature for a long time can make damage to cotton, but it can be tolerance of 125 ~ 150 ℃ high temperature short processing.

4. Microorganisms have damage on cotton fabric. Without mildew resistant performance.

The cotton fabric varieties

1. Made of pure cotton fabric

Pure cotton fabric woven from cotton yarn, fabric variety, design and color is different. Pure cotton fabrics, good permeability, hygroscopicity strong, comfortable to wear, but there is a prominent shortcomings - after washing and wearing easy corrugate, deformation. It can press the dyeing way is divided into grey fabric, dyeing cloth, calico, yarn-dyed cloth; Also can according to the fabric structure is divided into plain weave, twill, forging cloth.

2. Cotton blended, woven fabric

By the cotton and other fiber blended, woven fabric, collectively known as cotton blended, woven fabric. Here include the combination of cotton and other natural fiber, including the combination of cotton and all kinds of chemical fiber, cotton and chemical fiber usually combined into all sorts of breed of design and color fabric, the utility of the advantages of both parties.

(1) viscose and rich fiber and cotton blended textiles Commonly used 33% cotton, 33% viscose or polynosic. This kind of fabric has wear-resisting, the intensity is higher than that of viscose fabrics, hygroscopicity is better than pure cotton cloth, less wet strength decline, the characteristics of soft bright and clean. The main varieties have stick cotton, rich fiber cotton fabric.

2 terylene fabric Usually used 35% cotton and 65% polyester blended. This fabric mainly adopts the plain weave, high count for more thin shirt cloth, fine plain cloth, poplin, etc. Twill commonly known as "dacron," it keeps the polyester fiber with high intensity, good elastic recovery properties, and has the cotton moisture absorption strong, easy to dyeing, after washing wash-and-wear dry faster. Twill varieties and specifications, the original cloth, color cloth, calico, yarn-dyed fabric, and so on.

(3) d cotton goods whalen and cotton blended fabric. This fabric moisture absorption, data transparency are very good, and because of whalen brine corrosion resistance, so the d cotton blended fabric is suitable for making underwear, underwear, pajamas, etc. WeiMianBu drawback: dyed bright enough, less elastic. The main varieties have cotton calico, dimensions cotton plain cloth, cotton cloth and dimensions cotton yarn-dyed fabric grid cloth, etc.

(4) c cotton fabric The polypropylene short fiber and cotton blended by 1:1 proportion of plain weave fabric, common c cotton shirting and c cotton and linen yarn.

A. c cotton shirting: use 50% cotton and 50% polypropylene blends of plain fabric, its crisp appearance, small shrinkage, durability and durable, washable quick-drying, polyester-cotton fabric style. But the moisture absorption, heat resistance, light fastness is poorer, suitalbe for making garments.

B. c cotton and linen yarn: the 50% cotton and 50% polypropylene thin or 65% 35% polypropylene fiber and cotton blended fabric, yarn with cotton fabric appearance, but the moisture absorption, light resistance, heat resistance than cotton yarn. For summer shirt material or military raincoats, mosquito nets, etc.
