How many dyeing methods are there for textile fabrics? What are the stages of textile dyeing? The dyeing methods for textile fabrics can be divided into two types: dyeing (exhausted dyeing) and padding, and other textile dyeing methods are not limited to these two types.
There are roughly five stages of dyeing, namely, loose fiber dyeing, top dyeing, yarn dyeing, piece dyeing, and garment dyeing. Whether weaving fabrics or knitted fabrics, the proportion of piece dyeing is the highest, yarn dyeing is second, and other dyeing methods reflect each other, bringing together colorful fashion.
1. Dipping. The textile is dipped into the dyeing liquor and dyed with a dye and fixed in the fiber for a certain period of time.
Features: Suitable for dyeing various forms of textiles; intermittent production, low production efficiency; equipment is relatively simple and easy to operate.
2. Pad dyeing. The pad dyeing is the short-term impregnation of the textile fabric in the dyeing liquor, followed by rolling with rollers, squeezing the dye liquor into the interstitial spaces of the fabric, and removing the excess dye liquor so that the dye is evenly distributed on the fabric. Dyeing is (or mainly is) done in a subsequent steaming or curing process.
Features: Continuous dyeing process, high production efficiency, suitable for the dyeing of large quantities of textile fabrics, but the dyed material is subjected to a greater tension and is usually used for the dyeing of woven fabrics. Yarns and yarns are sometimes dyed with pad dyeing.
