Cotton cloth
Cotton fabric
miánbù, cottoncloth, cloth woven with cotton yarn. It is a general term for all types of cotton textiles. It is mostly used to make fashionable clothes, casual wear, underwear and shirts. Its advantages are easy to keep warm, soft and close-fitting, hygroscopic and breathable. Its disadvantages are that it is easy to shrink and wrinkle, and it is not very crisp and beautiful in appearance. It must be ironed frequently when wearing it. Reference: fine cotton, printed and dyed cotton, Songjiang cotton, Gaochang cotton, Northern Dynasties cotton.
Pinyin: miánbù
English: cottoncloth
Cotton cloth is a woven fabric made of cotton yarn as raw material; different varieties are derived due to different tissue specifications and different post-processing methods.
Cotton cloth is soft and comfortable to wear, warm, hygroscopic, highly breathable, and easy to dye and finish. Because of its natural characteristics, it has long been loved by people and has become an indispensable basic product in life.
The main features are as follows:
(1) It has good hygroscopicity and breathability, and is comfortable to wear; (2) It feels soft, has a soft and rustic luster; (3) It has good warmth retention and excellent wearing performance; (4) It has good dyeability, bright color and complete color spectrum. But the color fastness is not good enough; (5) Alkali resistance but not acid resistance. Treatment with concentrated alkali can round the fiber cross section in the fabric, thereby improving the gloss of the fabric, that is, mercerization effect. (6) Light resistance is good, but long-term exposure will cause Fading and reduced strength; (7) Poor elasticity, prone to wrinkles and creases that are difficult to recover; (8) Pure cotton fabrics are prone to mildew and deterioration, but are resistant to insects.
(1) Performance of cotton fabrics Cotton fiber is a single-cell cellulose fiber. One cell is a fiber. The main component of cotton fiber is cellulose. In addition, there are fat, sugar, ash and some water-soluble substances. Cotton fabric has all the characteristics of cotton fiber.
1. Strength The strength of cotton fabrics mainly depends on the length and twist number of cotton fibers. The longer the fiber length, the greater the twist number, and the greater the strength. The woven finished product will have better fastness and wear resistance. The strength of cotton lining is better than man-made fiber lining, but worse than other fibers.
2. Elastic cotton fibers have poor elasticity, so cotton fabrics wrinkle easily.
3. Hygroscopic cotton fiber is a porous material with a large hydrophilic structure in its molecules, so it has better hygroscopicity and better air permeability. The lining made of it is soft and comfortable.
4. Warmth-retaining cotton fiber is a poor conductor of tears. The inner cavity of the cotton fiber is filled with stagnant air. Therefore, the cotton fabric has good warmth retention and excellent wearing performance.
5. Dyeable cotton fabrics have good dyeing performance, bright colors and complete color spectrum, and can be matched with fabrics of various colors.
6． Other properties: Cotton cloth has poor alkali resistance and acid resistance, but good heat resistance and light resistance.
(2) Technical requirements for cotton fabrics
1. Width
Width within 100cm: Allowable deviation –1.0cm～+2.0cm
Width 100～140cm: Allowable deviation -1.5cm～+2.5cm
Width 140cm or more: Allowable deviation -2.0cm～+3.0cm
2. Density
Fabrics without major finishing: Allowable deviation – 1.5%
Large finishing preshrunk and fleece fabrics: allowable deviation – 2.5%
(Note: The sutra secret will not be assessed, but after the total sutra number is specified, it cannot be changed arbitrarily)
3.Dye fastness
Soaping fastness
Vat dye: fading level 3 as it is; white cloth staining level 4
Other dyes: fading level 3 as it is; white cloth staining level 3
Sulfide blue: fading as it is to level 3; white cloth staining level 2 to 3
Rubbing fastness
Vat dye: Dry rubbing level 3~4; Wet rubbing level 3
Other dyes: dry rubbing level 3; wet rubbing level 2
Sulfide blue: Dry rubbing level 3; Wet rubbing level 2
4.Shrinkage
Large finishing and preshrunk fabrics: warp direction not less than –5%; weft direction not less than –5%
Standard large finishing fabric: warp direction not less than –6%; weft direction not less than –5%
Common lining materials and uses
Cotton fabric lining
(1) Mainly commercial fabrics, coarse cloth, and plain cloth. The fabric is strong and wear-resistant, warm and comfortable, and is an affordable lining for cotton-padded clothes.
(2) Cotton/dimensional blended fabrics can be used as low-end suit linings.
Silk fabric linings and uses Pure silk silk linings are strong, stain-resistant, soft and comfortable, with a shrinkage rate of about 5%. They are ideal linings for silk and velvet clothing.
Pure fiber fabric lining and chemical fiber interwoven lining
(1) Pure fiber fabric, strong and wear-resistant, smooth and crisp, mainly used as down jacket lining and jacket lining.
(2) The rayon-interwoven satin lining is smooth, soft, comfortable, strong, and wear-resistant. It is an ideal lining for suits, fur coats, woolen coats, and down jackets.
(3) Rayon linings have a smooth satin surface, soft and smooth feel, soft color, and are not close-fitting. They are mainly used as velvet clothing linings.
(4) Cotton weft damask is made of intertwined rayon and cotton yarn. The silk surface is shiny, hard to the touch, and relatively smooth. It is suitable for lining casual wear. 5rzjkHO9c7
