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 fabrics use yarns of different colors to match the fabric to form various beautiful patterns, which are 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 the large losses in yarn dyeing, weaving, finishing and other processes, Taiwan’s production is not as high as that of white gray cloth, so the investment cost is high and the technical requirements are high.
Yan-dyed fabric is a fabric woven with dyed yarn. Yarn dyeing is generally divided into two methods: color spinning and dyeing yarn. Generally speaking, yarn-dyed fabric refers to woven fabric, but knitting The machine can also make yarn-dyed knitted fabrics. Compared with printed and dyed fabrics, it has a unique style, but the price is more expensive. Since the total loss of dyeing, weaving, and finishing of yarn-dyed fabrics is relatively large, the Taiwanese production is not as good as that of white gray fabrics. The output is 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. When printing and dyeing fabrics, you will generally find that some places are not colored when you peel off the yarn. 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 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 must be It cannot be used in the warp direction, but when 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.
Differences
1. Full-color weaving
A: In order to achieve different color effects – it is impossible to dye the same raw material with different colors after post-printing and dyeing, but it can be done with yarn-dyed weaving
/>B: Requirements for color fastness and shade – yarn-dyed products have good color fastness and good shade
C: Requirements for layering – require a good layering
2 , half-color weaving
Differences in warp and weft raw materials – using different warp and weft yarn raw materials to have different performance requirements for dyeing, half-color weaving can be used to reduce costs and increase patterns
In fact, judging whether the fabric is It is not just yarn-dyed fabrics
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 fabrics
There is another way to distinguish. For dyed fabrics, the fabric is woven first and then dyed, while for yarn-dyed fabrics, the yarn is dyed first and then woven. 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.
