Problems solved by technology

[0002] At present, the re-dyeing of all clothing and textiles belongs to water-phase dyeing, that is, the textiles are dyed evenly in a dye solution with a certain bath ratio. The disadvantages are: 1. Large energy waste; It is relatively large, which reduces the attraction and combination opportunities between dyes and fibers, and a large part of dyes become floating colors and is wasted; 3. Patterns and pleats are easy to appear, because relative movement between water and fabric is required to avoid patterns. If there is a short-term stop movement or uneven movement speed, patterns and colors will appear. The water-phase dyeing method is to immerse the clothes in the dye solution. After high temperature, it is easy to make the clothes pleated or deformed; Emissions will cause serious pollution to the environment; 5. Clothes cannot be partially dyed and fixed

Embodiment 1

[0023] A semi-new bright blue sweater weighing 500 grams was dyed bright green.

[0024] The dye weight of the above-mentioned brilliant blue sweater according to the calculation formula is:

[0025] 500×1%=5 grams

[0026] If 50% of the color is removed, the weight of the remaining dye is:

[0027] 5 x 50% = 2.5 grams

[0028] According to the principle of color matching, bright blue and bright yellow are combined into bright green, and the bright yellow dye is taken according to the medium color ratio;

[0029] Dye: Acid Bright Yellow 2G 5g

[0030] Acid Brilliant Blue 2.5g

[0031] Dyeing aid: Glacial acetic acid HAC 50ml

[0032] Leveling Agent O 10ml

[0033] Diffuser NNO 10ml

[0034] Penetrant JFC 10ml

[0035] Bath ratio: 1:10

[0036] First put the sweater in the steam dyeing room for 10 minutes under normal pressure, then take it out and wait for spray dyeing. Then dissolve the weighed dye with water at 20-40°C to make a dye so...

Embodiment 2

[0038] A pair of dark gray jeans, 500 grams, dyed into navy blue.

[0039] According to the calculation, it can be obtained that:

[0040] Dye: Direct Fast Blue B2RL 10g

[0041] Dyeing aid: NaCl 200g

[0042] Soda ash 10 grams

[0043] Silky Soap 5ml

[0044] Yuanming powder 5 grams

[0045] Diffuser NNO 10ml

[0046] Penetrant JFC 10ml

[0047] Liquor ratio: 1:8 Clothes steaming bath is the same as that of dissolving dye as in Example 1. Adjust the dyeing solution according to the liquor ratio of 1:8. After dissolving various auxiliaries, pour them into the dye vat, stir well, cover and heat , the rest of the process is the same as

[0048] Example 1 is the same.

Embodiment 3

[0050] A pair of dark gray jeans weighs about 500 grams, faded by 30%, and want to return to the original dark gray,

[0051] According to the calculation, the dye weight of the standard dark gray jeans is

[0052] 500 2% = 10 grams

[0053] fade color dye heavy

[0054] 10 grams 30% = 3 grams to take dye: direct ash D 3 grams

[0055] Auxiliary: 50 grams of table salt (NaCl)

[0056] Diffuser NNO 10ml

[0057] Leveling Agent O 10ml

[0058] Penetrant JFC 10ml Bath ratio: 1:10 Other processes are the same as in Example 1.

Abstract

A technology for dyeing the color fabric by high-temp and -pressure spray includes such steps as mixing dye with assistant, heating while pressurizing, spraying the mixture onto fabric, and high-temp and-pressure steaming for fixating color. Its advantages are low cost, short time, no deformation of fabric, high utilization rate of dye, and no pollution.

Description

Technical field: [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to an improvement of dyeing process and equipment for colored textiles.
