Washing requirements for clothing dyeing and washing

Classified by fabric
(1) Cotton and linen fabrics, such as plain cloth, poplin, khaki, labor cloth, bedding, etc., are suitable for mechanical washing because the washing temperature of cotton clothes can be higher than other fabrics, and the alkalinity of the washing solution can be stronger.
(2) Silk fabrics, such as satin clothing and embroidered duvet covers, are generally delicate in nature and have low color fastness. When washing, not only is the technical difficulty high, but the alkalinity and temperature of the washing solution must also be strictly controlled. Therefore, these types of clothes must not be mixed with other clothes, nor should they be washed with ordinary fabric and sweater washing solutions.
(3) Woolen fabrics, such as velveteen, Paris Saint Germain, Velvet, woolen blankets, sweaters, etc., are all high-end clothing with a wide variety of styles, varying thicknesses, and colors. Therefore, not only is the preparation of washing solution different from other fabrics, but the washing methods are also quite sophisticated, most of which are suitable for mechanical dry cleaning.
(4) Chemical fiber fabrics, such as synthetic cotton (silk, wool), acetate fiber, spandex, polyester, acrylic fiber, nylon, vinylon, etc. Their types and forms are more diverse and colorful than other fabrics, and they can also be blended with other fabrics. Therefore, the technology of such clothes is complex, especially with regard to temperature. For example, when washing acrylic expanded clothes at temperatures as high as 60 ° C to 70 ° C, it will deform and lose its style. For example, the wet strength of synthetic cotton (adhesive) clothes is only half of their dry strength, so the soaking time during the washing process should not be too long, and it is generally necessary to wash them as they are soaked.
