The dyeing of textiles can be carried out at any stage and can be dyed at different stages of the fiber, yarn, fabric and ready-to-wear.
1. Bulk fiber dyeing The dyeing of fibers or loose fibers before spinning is carried out in a large dyeing tank and dyed at an appropriate temperature. Most of the color spinning yarns are made by the method of bulk fiber dyeing (the effect of different fiber single dyeing), which is often used for woollen fabrics.
2, tops dyeing This is also the fiber dyeing before the fiber into the yarn, the same purpose as the fiber dyeing, in order to obtain a soft color mixing effect. Top dyeing is generally used for combing wool and wool fabrics.
3. Yarn dyeing The yarn is dyed before weaving, and is generally used for color fabrics, sweaters, etc. or directly using yarns (sewing threads, etc.). Yarn dyeing is the basis of dyeing and weaving. There are three ways to dye conventional yarns:
1 skein dyeing - immersing the loose skein in a special dyeing tank, which is the most costly dyeing method;
2 cheese dyeing - the yarn dyed by the cheese is wound on a perforated bobbin, and then many bobbins are placed in the dyeing tank, and the dye liquor circulates, and the fluffy effect and softness are not as good as the skein dyeing.
3 warp beam dyeing - is a large-scale package dyeing, the warp beam (warping) is made before the weaving, the whole warp beam yarn is dyed, such as the joint dyeing machine and the warp beam yarn. Bundle dyeing. Because it is a warp beam, it is suitable for woven dyeing. However, with the advent of the warp beam drop, we can drop the yarn on the warp beam after dyeing into a package yarn. This dyed yarn has a wider range of use, such as the reduction dyeing method mostly used for indigo dyeing. The warp beam dyeing can be solved very well, and it is difficult to achieve without the warp beam.
4. Piece dyeing The method of dyeing fabrics is piece dyeing. Common methods include rope dyeing, jet dyeing, roll dyeing, padding (not tie dyeing) and warp beam dyeing. I will not introduce them here.
5. Garment dyeing The garments are placed in a nylon bag, and a series of bags are placed together in the dyeing tank and continuously stirred in the dyeing tank (paddle dyeing machine). Apparel dyeing is suitable for some simple garments such as knit socks, T-shirts and other knitwear, sweaters, pants, shirts, etc.
