What are full-dyed and half-dyed fabrics? Basic knowledge of yarn-dyed fabrics

Disadvantages

dyed woven fabricUse dyed yarn fabric woven from threads,Giveyarn dyeingColors are generally divided into Colored spun and dyed yarn Two ways, The yarn-dyed fabric usually refers to shuttle loomcloth,But a knitting machine can also make itYarn-dyed knitted fabric ,It has a unique style compared to printed and dyed fabrics,But the price is expensive,Due to the relatively large total loss in dyeing, weaving and finishing of yarn-dyed fabrics,Taiwanese production is not as good as the output of white gray cloth High, So the cost increases.

Features

The color fastness is better, because it is dyed yarn first, and the color will penetrate into the yarn. Generally, if you peel off the yarn of printed and dyed fabrics, you will find that some places are not colored. The minimum order quantity is small. No matter what yarn weave, density, Textures and colors ranging from tens to hundreds of meters can be made, but it is difficult to customize dyed printed fabrics without gray fabrics, and the dyeing and printing process will also limit small batch production

Two categories

All-dyed weaving

There are dyed or partially dyed yarns in the warp and weft (or there are several colored yarns intertwined with white yarns in the fabric)

Half-dyed weaving

The warp or weft yarn is dyed or partially dyed. The gray yarn cannot be used to weave yarn-dyed fabrics because the tension and shrinkage of the gray yarn are different from those of dyed yarn, so it certainly cannot be used in the warp direction. , and when used in the weft direction, the cloth surface will be deformed due to shrinkage issues, so generally colorless yarns are semi-bleached or fully bleached.

Difference

1. All-dyed weaving:

A In order to achieve different color effects – it is impossible to dye the same raw material with different colors after printing and dyeing, but it can be done by using yarn-dyed weaving

B Color fastness and color light requirements – yarn-dyed weaving The product has good color fastness and good color feel

C Requirements for layering—requiring a good layering

2. Semi-dyed weaving: different warp and weft raw materials – different performance requirements for dyeing due to different warp and weft yarn raw materials, semi-dyed weaving can be used Yarn-dyed weaving to reduce costs and increase styles

In fact, it is very simple to judge whether the fabric is yarn-dyed fabric

Basically two or more colors and the same composition (such as 100% cotton, 100% polyester) are basically yarn-dyed fabrics. If it is plain color, it depends on the fabricQuality and color fastness. Generally, the quality of plain fabrics made from yarn-dyed fabrics is better than that of dyed fabrics. The cloth surface is fresh and dryClear. The fastness is also higher than that of dyed cloth

There is another way to distinguish. For dyed fabrics, the fabric is woven first and then dyed. For yarn-dyed fabrics, the yarn is dyed first and then weaved. Therefore, generally yarn-dyed fabrics If it’s dyeing, just look at the front and back. If it doesn’t work, pull out the thread, If the inside and outside are the same color, it is yarn-dyed fabric, but if the outside surface has a layer of color, it is dyed fabric.
