Yarn-dyed weaving refers to a process in which yarn or filament is dyed first and then used to weave cloth with colored yarn. The colors of yarn-dyed fabrics are mostly bright and bright, and the patterns are also distinguished by color contrast.
Advantages ：
Yarn-dyed fabric uses yarns of different colors to match the fabric to form a variety of beautiful patterns, which is more three-dimensional than ordinary printed fabrics.
Because the yarn-dyed fabric is dyed with raw yarn, the dye has strong penetrability, so the dye fastness is good.
Multi-shuttle and dobby weaving are used to weave yarn-dyed fabrics, which can interweave different fibers or different yarn counts into varieties with rich colors and clever patterns.
Because yarn-dyed fabrics use colored yarns or patterned yarns and various tissue changes, poor-quality cotton yarns can still be woven into beautiful varieties.
Disadvantages:
Due to dyeing The losses in yarn, weaving, finishing and other processes are relatively large, and Taiwan’s production is not as high as that of white gray cloth, so the input cost is high and the technical requirements are high.
Yarn-dyed fabric is a fabric woven with dyed yarn. Yarn dyeing is generally divided into two methods: color spinning and dyeing yarn. Usually, yarn-dyed fabric refers to Fabrics woven by tatting machines, but knitting machines can also make yarn-dyed knitted fabrics. Compared with printed and dyed fabrics, they have a unique style, but are more expensive. Due to the relatively high total losses in dyeing, weaving, and finishing of yarn-dyed fabrics, The production in Taiwan is not as high as that of white gray cloth, so the cost increases.
Features: The color fastness is better, because it is dyed yarn first, and the color will penetrate into the yarn, while printed and dyed fabrics Generally, if you peel off the gauze and look at it, you will find that there are places where there is no coloring. Minimum order quantity is small. No matter what yarn weave, density, texture, or color, it can be made from tens to hundreds of meters. However, it is difficult to specially customize dyed printed fabrics without gray fabrics, and the dyeing and printing process will also limit small batch production.
Full-dyed weaving: There are dyed or partially dyed yarns in the warp and weft (or there are several colored yarns interwoven with white yarns in the fabric).
Half-dyed weaving: The warp or weft yarns are 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 the yarn. The dyed yarn is different, so it definitely cannot be used in the warp direction. If used in the weft direction, the cloth surface will be deformed due to shrinkage issues during finishing. Therefore, generally colorless yarns are semi-bleached or fully bleached.
Difference
1. All-dyed weaving
A: In order to achieve different color effects – it is not possible to dye the same raw material in different colors after post-printing and dyeing, but it can be done with yarn-dyed weaving. To
B: Requirements for color fastness and shade – yarn-dyed products have good color fastness and good shade feeling
C: Requirements for a sense of layering – a good sense of layering
2. Half-dyed weaving
Differences in warp and weft raw materials – using different warp and weft yarn raw materials to have different performance requirements for dyeing, half-dyed weaving can be used to reduce costs and increase styles.
Basically, two or more colors and the same composition (such as 100% cotton, 100% polyester) are basically yarn-dyed fabrics. If it is a plain color, it depends on the quality and color fastness of the fabric. Generally, the quality of plain fabrics made from yarn-dyed fabrics is better than that of dyed fabrics. The fabric surface is fresh and the lines are clear. 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, when it comes to yarn-dyed fabrics and dyeing, just look at the front and back. If that doesn’t work, pull out a thread. If the inside and outside are the same color, it’s yarn-dyed, but if there’s a layer of color on the outside, it’s dyed fabric. </p
