Dyeing process of dyed fabric

Practice bleaching to remove impurities contained in natural fibers, and in the textile processing process and join the various slurries, oils and stained dirt, etc.. The presence of these impurities, both impede the smooth progress of dyeing and finishing process, but also affect the performance of the fabric. The purpose of practice bleaching is the application of chemical and physical-mechanical effects, remove impurities on the fabric, so that the fabric is white, soft, with good penetration properties to meet the requirements for taking, and for dyeing, printing, finishing to provide qualified semi-products. Dyeing is a more complex process, different qualities of cloth dyeing process is different, cotton, polyester-cotton, nylon, polyester, chemical fiber products, blended products and so on. Some use roll dyeing, roll dyeing can be, some must use high temperature and high pressure dyeing, some dyeing only once, some to be colored many times.

While the dyeing can be done by a rolling car, it is also the most difficult process, because the color control of the dyeing in addition to the known, there are a lot of unknown things in it, such as the stability of the dye at different temperatures, the control of the steam, the control of the pressure of the rolling car and so on, it is a very delicate work.

Dyeing is a very delicate job.

The dyeing of the long car is divided into two parts, the front car dyeing, after the car solid color. Dyeing method according to the selection of different varieties of dyes and there are differences, dyes are generally reactive, serin, vulcanization, paint. They have their own advantages and disadvantages, generally depends on the required color, and can not replace each other. Finishing is the textile technology engineering that gives clothing fabrics the performance and beauty. The following are the common types of textile finishing:, the main equipment are: burnishing machine, desizing machine, mercerizing machine, liquid ammonia machine, shaping machine, pre-shrinking machine, rolling machine, washing machine, abrasive machine, wool grasping machine, coating machine and so on.
