Xiaobian: I Learned Knowledge Of Clothes And Fabrics Three

direct dyestuff Direct water soluble anionic dyes directly dye almost all natural fibers and regenerated fibers: viscose, Tencel.

It has higher dye uptake and fastness on viscose fiber and more applications.

Acid dyes: acid water-soluble anionic dyes, can not dye cellulose fibers, can be dyed protein fiber: wool, silk and nylon.

Reactive dyes: reaction water-soluble anionic dyes, mainly dyed cotton fibers. It has wide chromatography, bright color and low cost.

Vat dyes: VAT non water soluble dyes, mainly used for dark dyeing of cotton fabrics. The chromatogram is complete, the color is bright, and the fastness is excellent. It is a high-grade dyestuff for printing.

　　 Cationic dyes Cationic: it is special for acrylic fiber, and can also be used for protein fiber to a certain extent, but its fastness is not good.

Disperse dyes: the preferred dyes for disperse polyester and all other hydrophobic synthetic fibers.

Insoluble azo dye: naphthol, also called NaF dye, is mainly used for cotton cloth, mainly red.

Enzyme wash: Enzyme wash

Seco-tex: a commercial name for moisture absorbent and sweating yarn produced by Li Li.

Double dye (two tone):T/CD (T:polyeater, CD:cationic dyes, CD is a kind of polyester. T:50%, CD:50%, intertwined). When the fabric is dyed, CD can be dyed with disperse dyes or base dyes, while T only accepts disperse dyes, and the base dyes do not respond to T. Therefore, disperse dyes and basicity two dyes were dyed in the T/CD vats, resulting in two colors.

Total shrinkage: the percentage of shrinkage of textured yarns after heating, which is related to the amplitude of woven fabrics.

Full volume shrinkage: represents the volume shrinkage of the textured yarns at room temperature and the sum of the volume shrinkage produced after heating.

PTT: the full name is polytrimethylene Terephthalate, which can be dyed at ambient temperature and atmospheric pressure at 120 degrees. It is environmentally friendly. Many properties are superior to nylon. The main direction is to replace nylon, but it is not very mature.

Characteristics of commonly used fibers:

　　 Cotton fiber They are thin, soft and short, with different lengths.

Ma: rough, hard, light yellow, it is difficult to distinguish a single fiber.

Wool: longer than cotton fiber, length 60-120mm. The handle is plump and elastic, and the fibers are curly and milky white.

Silk: long and uniform long fiber, fineness and slender, soft handle, soft luster, and silk feel. The color is extremely pale yellow. The length of a cocoon filament is 600-1200mm.

Bright rayon: White has a dazzling luster, soft handle, but not as clear as silk, with a silk feel and wet strength.

Polyester: cool and strong, strong, flexible, and easy to deform.

Nylon: it has wax light, strong strength, good elasticity, and is easier to deform than polyester.

Characteristics of commonly used fabrics:

Silk fabric: bright, soft, bright, thin and elegant.

Cotton fabric: glossy, soft but not smooth with natural cotton, grey fabric and cottonseed chips.

Wool fabric: worsted fabric with smooth finish, clear texture, soft luster, rich body bones, good elasticity and smooth touch.

The woolen fabric is rich, soft, elastic and light.

Linen fabric: hard and cool.

Polyester fabric: the handle is very cool, elastic, not easy to wrinkle, flash in the sun.

Nylon fabric: it feels more slippery than polyester, but wrinkles easily than polyester.

Acrylic fabric: fluffy and stretchable, similar to woolen fabric but not woolen fabric.

Vinylon fabric: similar to cotton fabric, but less than cotton fabric, soft and bright.

The tribute is woven with weft Satin weft, which appears on the surface of the fabric and has a satin style. Therefore, it is also called satin satin. Its fabric is smooth, soft and glossy.

Pet bottle flake: polyester chip

Quilt: coil density for knitted fabrics.

Drop needle: leak needle

Rib: rib tissue

Interlock: double rib organization

Fabric item: Terry

PA transparent adhesive: Acrylic invisible

White glue: Milky coating. silver adhesive: Silver coating. color adhesive: Color coating.

Black gum: Black coating. gold glue: Golden coating.

PU waterproof and moisture permeable:

Ribstop: grid, ribstop effect: has the effect of grid effect in organization.
