Embodiment 1

[0030] A kind of environmental protection dyeing method concrete steps of multifunctional denim fabric are as follows:

[0031] (a) Weaving

[0032] The multifunctional denim fabric is woven by blending four kinds of fibers including spandex fiber, polyester fiber, melton fiber and apocynum fiber. The weight percentages of each component in the multifunctional denim fabric are respectively: spandex fiber accounts for 15%, polyester fiber Fiber accounts for 18%, Melton fiber accounts for 56%, Apocynum fiber accounts for 11%;

[0033] (b) desizing

[0034] Add 1g of BF--7658 amylase, 2g of salt, 1g of penetrant and 0.5mL of glacial acetic acid to each liter of water to make a slurry. , put the denim fabric in the slurry to fully hydrolyze the starch;

[0035] (c) Cellulase finishing

[0036] Add cellulase that accounts for 1.0% of the weight of the clothes in the finishing tank, control the temperature in the finishing tank to 50°C, and the pH value to 4.5, place the denim f...

Abstract

The invention discloses an environment-friendly dyeing method for multifunctional denim fabrics. The method comprises the specific process steps as follows: weaving, desizing, cellulase finishing, baking, dyeing, application of a softener, baking, non-iron finishing and packaging. Size on clothing is removed by desizing, and the denim fabrics meeting requirements can be prepared by biological polishing finishing and non-iron finishing; the effect is obvious, better practical value is realized, and the process is energy-saving and environment-friendly; the denim fabrics dyed with the method have quite good wet fastness and sunlight fastness, and the problems of shade and color changes and proneness to fade in the prior art are solved.

Description

technical field [0001] The invention relates to the field of clothing fabrics, in particular to an environmentally friendly dyeing method for multifunctional denim fabrics. Background technique [0002] In the 1980s, US denim production accounted for 50% of global production, but in the last decade, China, India, Pakistan, Malaysia, Turkey and Mexico have established a large number of denim production plants, and the US and even The world's denim production center has shifted to countries with low labor costs in Asia. Denim is also called cracked silk. It is a thicker yarn-dyed warp-faced twill cotton fabric. The warp yarn is dark in color, generally indigo blue, and the weft yarn is light in color. It is light gray or boiled white yarn, also known as indigo denim. It began in the west of the United States, and it was named after the shepherds used it to make clothes. [0003] Traditional denim fabrics are simply woven from one set of dyed yarns and another set of off-whit...
