Problems solved by technology

[0005] The dyeing shade of this formula is obviously darker and cannot meet the customer's requirements, so this formula process cannot be used
[0006] Now the traditional dyeing process of fluorescent paint for garments is as follows: first bleaching and shaping in the dyeing factory, then to the garment factory for garment dyeing, then to the washing factory for garment dyeing, and finally back to the garment factory, the process is complicated and the cost is higher than that of gray fabric overflow fluorescence Dyeing, so can't use this process

Embodiment 1

[0027] The method for dyeing bright fluorescent pink on cotton knitwear comprises the following process steps:

[0028] 1) The gray cloth is firstly depilated in the air cylinder, and then pre-treated at a high temperature of 110°C;

[0029] 2) Dyeing in the overflow tank, the bath ratio is 1:25, first add glacial acetic acid HAC 0.5% to adjust the pH value to 5-6;

[0030] 3) Raise the temperature to 40°C for 15 minutes and add 6-8% of ADK-260 cationic modifier. After running for 5 minutes, raise the temperature to 70°C at 1°C / min and keep it for 40 minutes;

[0031] 4) Drain once;

[0032] 5) Inlet water, bath ratio 1:25, run for 5 minutes, heat up to 40°C, measure for 20 minutes, add fluorescent paint orange red S-004 7-9%, run for 5 minutes, then raise to 70°C at 1°C / min Cut the sample after 40 minutes of heat preservation;

[0033] 6) Proof;

[0034] 7) After checking the sample, wash it twice with water and take it out of the tank;

[0035] 8) Soak in the bucket out...

Embodiment 2

[0041] The method for dyeing bright fluorescent pink on cotton knitwear comprises the following process steps:

[0042] 1) The gray cloth is firstly depilated in the air cylinder, and then pre-treated at a high temperature of 110°C;

[0043] 2) Dyeing in the overflow tank, the bath ratio is 1:25, first add glacial acetic acid HAC 0.5% to adjust the pH value to 5-6;

[0044] 3) Raise the temperature to 40°C for 15 minutes and add 7% of ADK-260 cationic modifier. After running for 5 minutes, raise the temperature to 70°C at 1°C / min and keep it for 40 minutes;

[0045] 4) Drain once;

[0046] 5) Inlet water, bath ratio 1:25, after running for 5 minutes, raise the temperature to 40°C and measure for 20 minutes, add fluorescent paint orange red S-004 8%, after running for 5 minutes, then raise the temperature to 70°C at 1°C / min and keep warm for 40 cut in minutes;

[0047] 6) Proof;

[0048] 7) After checking the sample, wash it twice with water and take it out of the tank;

Abstract

The invention relates to a method for dyeing cotton knitwear, in particular to a method for dyeing cotton knitwear in bright fluorescent pink. The method includes firstly, removing hair in an air cylinder before high-temperature pretreatment; secondly, dyeing an overflowing cylinder, and adding HAC (ethanoic acid) to regulate PH to 5-6; thirdly, measuring and adding ADK (adenylate kinase)-260 cation modifier; fourthly, discharging water once; fifthly, allowing for water inflowing, and adding fluorescent pigment vermilion S-004; sixthly, performing sample comparison; seventhly, washing twice after sample comparison, and taking out of the cylinder; eighthly, soaking in a scoop outside the cylinder, and adding ADK-101 adhesive; ninthly, dewatering and drying; and tenthly, shaping. The condition that reactive dye cannot be used to dye bright fluorescent pink conventionally is broken through, the fluorescent pigment is selected for dyeing, and accordingly gorgeous and bright fluorescent dyeing effect is achieved. By the steps of the method, the requirement of customers for color brightness is met, and corresponding quality index is met.

Description

technical field [0001] The invention relates to a method for dyeing cotton knitwear, in particular to a method for dyeing cotton knitwear with bright fluorescent pink. Background technique [0002] Cotton knitted gray fabric sample dyeing processing, customers provide sample fabrics, some provide color samples with very bright color, but the current reactive dye chromatogram lacks a complete set of fluorescent chromatograms (inactive fluorescent pink), and the conventional dyeing formula process is basically Not meeting the requirements. [0003] In general, the bright pink dyeing of cotton knitwear is dyed with the most vivid dye in reactive dyes, and the formula is example: [0004] Reactive red SHR-GD, red, active orange F-2R, salt: 10%, soda ash: 5%. [0005] The dyeing shade of this formula is obviously darker and cannot meet the customer's requirements, so this formula process cannot be used. [0006] Now the traditional dyeing process of fluorescent paint for garme...
