Abstract

By a cleaning-free process for efficiently and quickly dyeing a polyester fabric, the polyester fabric is dyed, and directly dehydrated, opened and set without being cleaned; dyeing time is 50 to 70 percent of that of the conventional process; the using amount of a dye is reduced by 5 to 20 percent; the rate of exhausting the dye by a dark and special dark product can be over 98 percent; the chemical oxygen demand (COD) value of dyeing residual liquid is reduced, the product is not required to be cleaned when discharged from a jar, the emission of sewage is reduced by 30 to 75 percent, and the dyed finished product meets the national standard of ecological textiles; and by the polyester cleaning-free process, a large amount of steam, electric energy and water are saved, a large amount of cleaning sewage is not generated, the aims of saving energy and reducing emission are fulfilled, and color fastness meets the national textile standard.

Description

The efficient rapid dyeing of dacron is cleaning and using method not

Technical field:

The present invention relates to the textile dyeing industry, specifically be meant the efficient rapid dyeing of a kind of dacron not cleaning and using method.

Prior art:

Because the character of terylene and DISPERSE DYES, the colouring method of traditional DISPERSE DYES mainly contain three kinds of hot melt, support methods and high temperature and high pressure methods at present.Hot melt dyeing can be carried out serialization production, efficient height, but the utilization rate of dyestuff is low, and equipment has high input, and it is more coarse to dye product feel, and colour brightness is general, and (E type dye should not) selected and be restricted to dyestuff for use.Support methods can be utilized the carrier property plasticized fibre, reduces the vitrification point of fiber, and can make the reduced gravity between the terylene strand, make fiber form bigger space, thereby make dyestuff enter fibrous inside, dyeing installation is simple, dyeing condition is low, but dyeing formality trouble, the cost height, most importantly carrier is influential to dyefastness and color and luster, high temperature easily decomposes, volatilization, and its gas is poisonous, harmful, cause environmental pollution.High temperature and high pressure method dyes because the temperature height helps the DISPERSE DYES diffusion, can obtain going up preferably chromatic effect, and equipment is popularized, and is easy to operate, and therefore most of dye-works still adopts the method to carry out dyeing terylene.But this high-temperature and high pressure dyeing process colouring time is longer, generally adopts High Temperature High Pressure open width dyeing machine, and the High Temperature High Pressure overflow dyeing machine on average whenever dyed a cylinder cloth 4～5 hours consuming time, and production efficiency is low.Particularly the wash phase operation of this colouring method is more and complicated, in order to reduce the cloth cover loose colour, improve the product COLOR FASTNESS, colouring is not only wanted the multiple tracks water outlet after finishing, and often carries out reduction cleaning, measure such as soap, so whenever, dying 300 kilograms of cloth needs more than 10 ton of water, causes energy resource consumption big, dyeing cost height, problems such as sewage discharge is serious are unfavorable for the sustainable development of dyeing.

Summary of the invention:

The present invention is intended to propose a kind of efficient rapid dyeing of dacron not cleaning and using method of being used for.Adopt dacron dyeing of the present invention, do not need to clean directly dehydration, open-width, typing after the dyeing.Employing the present invention dyeing, the time is the 50-70% of traditional handicraft; Save dye dosage 5-20%; The exhaustion rate of dark, special dark product dyestuff can reach more than 98%; Dyeing residual liquid COD value descends, and goes out cylinder and need not to clean, and reduces quantity of wastewater effluent 30-75%, and the dyeing finished product reaches the ecological textile national standard, and COLOR FASTNESS reaches national textile standards.Terylene is a large amount of steam of cleaning saving not, and electric energy and water have not had a large amount of cleaning sullages, have reached the purpose of energy-saving and emission-reduction.

Embodiment:

For realizing above purpose, the present invention realizes by the following aspects:

1, adopts dyeing terylene catalyst D-A1, the dyeing terylene healant D-A2 of independent research, can increase substantially the dye-uptake of dyestuff, reach with common DISPERSE DYES rapid dyeing purpose.(production of Jiaxing Yuan Chang printing technology research institute)

2, the technological process of the present invention's employing:

2.1 dyeing prescription: the part by weight of pressing pollutant adds dyestuff

0.1-5% (o.w.f) dyeing terylene catalyst D-A1

0.1-0.8g/L dyeing terylene healant D-A2

The conditioning agent that adopts is that sulfuric acid, hydrochloric acid, formic acid, glacial acetic acid, control pH value are at 3-6.5

Press 1: 15 bath ratio dyeing of pollutant.

2.2 heating curve:

Light-coloured prods: dyeing rate is that 3 ℃/min is raised to 70 ℃, and 1 ℃/min-1.5 ℃/min is warmed up to 120 ℃-135 ℃, is incubated 30 minutes, and 1-3 ℃/min reduces to 80 ℃ then.

In dark product: dyeing rate is that 3 ℃/min is raised to 90 ℃, and 1 ℃/min-2 ℃/min is warmed up to 120 ℃-135 ℃, is incubated 30-50 minute, and 1-3 ℃/min reduces to 80 ℃ then.

2.3 go out cylinder: can not wash, directly go out cloth; Also can put a cylinder clear water, reduce the cloth surface temperature.The former is applicable to the situation of the dehydration in time of dyeing back, open-width, typing, and the latter is applicable to situation about can not in time dewater after the dyeing.

The present invention adopts above scheme, can reach the purpose of rapidly and efficiently not cleaning, and its technological process is technical recipe-draw a design-dye-go out cylinder-dehydration-open-width-typing-check-finished product.
