Dyeing method:

The dyeing of textiles can be carried out at any stage and at different stages, such as fiber, yarn, fabric and clothing:

1, bulk fiber dyeing Put the fiber or bulk fiber dyed before spinning into a large dyeing vat and dye it at a proper temperature. Color spinning mostly adopts the method of bulk fiber dyeing (also has the effect of single dyeing of different fibers), which is often used for wool fabrics.

2. Top dyeing This also belongs to fiber dyeing before fiber spinning. Like the purpose of bulk fiber dyeing, it is to obtain a soft mixed color effect. Top dyeing is generally used for combing wool yarn and wool fabric.

3. Dye the yarn before weaving, which is generally used for colored fabrics and sweaters. Or directly use yarn (sewing thread, etc. ). Yarn dyeing is the basis of dyeing and weaving.

There are three methods for conventional yarn dyeing:

(1) hank dyeing-soaking loose hank yarn in a special dyeing vat is the most expensive dyeing method;

(2) bobbin dyeing: the yarn dyed by bobbin is wound on a perforated bobbin, and then a large number of bobbins are put into the dyeing vat, and the dyeing solution is circulated, so the fluffy effect and softness are not as good as those of hank dyeing.

(3) beam dyeing-large package dyeing. Before weaving, it is necessary to make a warp beam (warping) to dye the yarn of the whole warp beam, such as the combination of sizing machine and warp beam dyeing. Because it is a beam, it is mostly suitable for weaving and dyeing. But with the appearance of warp beam doffing, we can change the colored yarn on the warp beam into cheese.

4. The method of dyeing fabrics in piece dyeing is piece dyeing, and the commonly used methods are rope dyeing, jet dyeing, package dyeing, pad dyeing (not tie dyeing) and beam dyeing. I won't introduce it here.

5. Dyeing of ready-made clothes: put the ready-made clothes into nylon bags, put a series of bags together in a dyeing vat, and constantly stir them in the vat (paddle dyeing machine). Clothing dyeing is mostly suitable for knitted clothing such as knitted socks and T-shirts, and simple clothing such as sweaters, trousers and shirts.

6. Artistic dyeing-mainly including tie-dyeing, batik, hanging dyeing, segment dyeing, splash dyeing and hand painting.

7. In the dyeing process, it is best to use clips made of all plastics to fix the fabric to prevent the spring metal ring from rusting and polluting the fabric because it cannot tolerate acid or alkaline dyes. Therefore, the use of pure plastic clips is the most suitable and safest clip, which is easy to buy on Taobao.
