Method for preparing billet yarns into color yarns

Abstract

The invention discloses a method for preparing billet yarns into color yarns, aiming at providing a color yarn preparing method which can obviously reduce consumption of heat and water in the color yarn manufacturing process and reduce pollution to the environment in the production process. The method comprises the following sequential formulas and processes of: a degreasing and bleaching formulaand process, a washing process, a neutralizing formula and process, a washing process, a dyeing formula and process, a cooling and washing process, a neutralizing formula and process, a soaping formula and process, a color fixing formula and process, a dehydrating process and a drying process. The main point of the technical scheme of the method is that the ultrasonic effect is added in the yarn degreasing, bleaching and dip-dyeing process according to the characteristic that ultrasonic waves with high strength and high power can generate a lot of ultramicro bubbles and instant high temperature and high pressure in a solution. Compared with the traditional method, by means of the method for preparing billet yarns into color yarns, heat, water and organic dye for producing color yarns withsame quantity can be obviously reduced; and most importantly the pollution to the environment in the production process is greatly reduced.

Description

technical field [0001] The invention relates to a yarn manufacturing method, more specifically, a method of making colored yarn from gray yarn. Background technique [0002] my country is a big exporter of textiles, and textile exports account for a large proportion of my country's annual total exports. However, due to the consumption of a large amount of heat and water in the manufacturing process of the raw material yarn of textiles, coupled with the current dyeing and finishing technology and Compared with developed countries, the printing and dyeing wastewater treatment technology is still relatively backward. Therefore, while the textile industry has created huge economic benefits for the country, it has also brought us huge energy supply pressure and environmental pollution pressure. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and to provide an improved method of producing colored threads. T...
