Problems solved by technology

However, the raw cotton yarn is dyed with indigo and sulfur black on the sizing-dyeing machine or the ball warp dyeing machine. Due to the equipment and process, the garments made of indigo and sulfur black dyed have serious color fading, and the wet rubbing fastness is extremely poor, only the lowest. Level 1, the color fastness to multi-fiber staining is also very poor, which makes it impossible to match with light-colored clothes, let alone match with white clothes, and the staining will be more serious when washed together
[0004] In the denim clothing market, paint dyeing has been used to imitate the layering of denim. Due to the adhesive and crosslinking agent of the paint, the degree of decolorization of the paint is single, and the washing effect of denim clothing with distinct layers cannot be achieved; laser etching is also used to To imitate the layering of denim clothing, but the cost of laser etching is too high, and a large amount of harmful gas will be generated during the process. After laser etching, a large amount of high-color sewage will be generated to remove the weaving slurry

Embodiment 1

[0032] A kind of manufacture method of blue denim yarn, comprises the steps:

[0033] The first step is the pre-dyeing treatment of cotton loose fibers, which is used to remove grease and wax on cotton loose fibers, enhance the permeability of cotton loose fibers, and improve the dye uptake rate during dyeing;

[0034] The second step, cotton loose fiber dyeing: add dye, that is, vat dye leuco dye solution, heat at a heating rate of 0.5°C / min, when the temperature reaches 50°C, keep warm for 70min, and keep warm for 20 minutes and 40 minutes Add the dyeing accelerator in 10 minutes, the dyeing accelerator is preferably Yuanming powder, and the consumption of twice adding the dyeing accelerator is 15g / L;

[0035] The third step is post-dyeing treatment of cotton loose fiber;

[0036] The fourth step, blending and spinning: dyed cotton loose fibers and undyed cotton loose fibers are mixed and spun, wherein the dyed cotton loose fibers account for 50%.

[0037] Among them, dyei...

Abstract

The invention provides a manufacturing method of colorized denim yarn. The manufacturing method comprises the following steps that firstly, cotton loose fibers are subjected to deying pretreatment including treatment adopting pretreatment auxiliaries; secondly, vat dye leuco body dyeing work fluid is added into the cotton loose fibers prepared in the first step, heating is carried out at the temperature increase rate of 0.5-1 DEG C / min, when the temperature reaches 50-85 DEG C, heat preservation is carried out for 10-70 min, and an accelerant is added during heat preservation; thirdly, dyeingaftertreatment of the cotton loose fibers is carried out; and fourthly, the cotton loose fibers prepared in the third step and non-dyed cotton loose fibers are mixed for spinning. Fabric formed by weaving the yarn manufactured through the method is good in dyefastness and is not prone to fading during washing.

Description

technical field [0001] The invention belongs to the technical field of denim dyeing and finishing and garment production, and in particular relates to a production method of colored denim yarn and fabrics and garments produced by using the yarn. Background technique [0002] Beautiful denim clothing is deeply loved by consumers and has a large market sales. According to relevant data, the global denim clothing market has increased by 8.9% from 2013 to 2018, from US$52.6 billion to US$57.3 billion, and is expected to reach an annual market volume of US$60 billion by 2023. [0003] Conventional denim clothing is mainly made of indigo and sulfur black dyed fabrics. At present, most denim fabrics use raw cotton yarns to go through the sizing and dyeing machine or the ball dyeing machine, and then go to weave. After the pre-shrinking treatment, it is sent to the garment factory. After the garment is produced, it is washed by various methods to achieve the effect of washing old a...
