Abstract

The invention relates to a dyeing method of cloth, which is realize through the following steps of: preparing one ton of gray cloth; then piping; trimming the cloth; then entering a cold pad machine for cold pad treatment; carrying out the cold pad treatment for 8-10 minutes, and then stacking in a cloth trolley; striking by using a plastic bag, and stacking at the constant temperature of 26-28 DEG C for 12 hours; then starting to dye for about 3 hours; cleaning, cutting plates and checking colors after two hours; then washing fastness by needing three vats of water; and carrying out the softening treatment in the cold pad machine for 8-10 minutes. The invention has short vat occupying time and can enhance the utilization rate of the vats and increases one vat 24 hours a day.

Description

The colouring method of cloth

Technical field

The present invention relates to a kind of colouring method, relate in particular to a kind of colouring method of cloth.

Background technology

The dyeing of cloth generally realizes by following steps in the prior art:

Embryo cloth was equipped with embryo before this, bound off again, and removing the work follows into that cylinder floats the end; Floating end needs 2.5 hours, is example with 1 ton of cloth, and needing 12 tons of water to add the hydrogen peroxide ratio simultaneously for the first time is auxiliary agents such as 5%-6%, soda ash 1.2%, refining agent 1.5%, anti wrinkling agent 1%-2%, the yarn agent 1%-2% that deoils; Need to heat up 98 ℃ 60 minutes; Wash water for the second time, 12 tons of water of wash clean, 60 ℃; Acid treatment for the third time, 60 ℃ of 12 tons of water of pH value test; Behind the 4th wash clean, hot water emits, 12 tons in 98 ℃ of water;

Begin dyeing again; About 3 hours times spent, add dyestuff, heating up 60 ℃ adds soda ash, dye leveller;

Cleaning, shear after 2 hours, check colors, wash fastness again, need three cylinder water;

Add softener again, again cleaning, shear, check colors, go out cylinder, need 1.5 hours.

Altogether about 9 hours times spent (accounting for the cylinder time).

Must float through high temperature oxygen in the above-mentioned steps and remove embryo cloth surface grease, seed coat and other impurity, the required dye uptake and the fineness of embryo cloth, the vividness of color in the time of just reaching dyeing; The weak point that conventional oxygen floats is high temperature (98 degree * 1 hour), and required steam consumption is big, and oxygen floats and need wash down residual auxiliary agent, impurity on the embryo cloth with recirculated water several times continuously after finishing, and it is big to make embryo cloth reach normal dyeing requirement water consumption; Relatively hair is thick for surface smoothness after floating through high temperature oxygen in addition.Embryo cloth quality feel is poor, and the embryo cloth that floats through high temperature oxygen (piece together line, twist thread, single jerseys such as OE, open-end spinning) all has fine wrinkle to have (this be in the dyeing industry the thing of trouble), must take the dye vat time when oxygen floats to be about 2.5 hours and to be unfavorable for increasing dyeing output.

Summary of the invention

The technical issues that need to address of the present invention have provided a kind of colouring method of cloth, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the present invention realizes by following steps:

1 ton of embryo cloth is equipped with embryo, binds off again, and removing the work is followed into cold dome machine cold dome processing;

After carrying out cold dome processing in 8-10 minute, stack the cloth car, prick into, stacked 12 hours at 26 ℃ of-28 ℃ of constant temperature with plastic bag;

Begin dyeing again; About 3 hours times spent;

Cleaning, shear after 2 hours, check colors, wash fastness again, need three cylinder water;

Carry out 8-10 minute cold dome machine soft treatment.

Compared with prior art, the invention has the beneficial effects as follows: account for cylinder time weak point, can increase the utilization rate of cylinder, 24 hours every days, can increase by a cylinder every day.

The specific embodiment

Below in conjunction with the specific embodiment the present invention is described in further detail:

The present invention realizes by following steps:

1 ton of embryo cloth is equipped with embryo, binds off again, and removing the work is followed into cold dome machine cold dome processing;

After carrying out cold dome processing in 8-10 minute, stack the cloth car, prick into, stacked 12 hours at 26 ℃ of-28 ℃ of constant temperature with plastic bag;

Begin dyeing again; About 3 hours times spent;

Cleaning, shear after 2 hours, check colors, wash fastness again, need three cylinder water;

Carry out 8-10 minute cold dome machine soft treatment.

The present invention replaces of the prior artly to advance cylinder and float the end and softness by carry out cold dome and soft processing at the cold dome machine, has shortened to advance cylinder and float the end and soft 2.5 hours and 1.5 hours, and the 4 hour time of cylinder is advanced in shortening altogether.

The cold dome machine that the present invention adopts is that Wuxi textile dyeing machinery factory produces.

Cold batching process enable the holding time that has reduced cylinder in principle, improved production capacity, saved many auxiliary agents and water and steam, saved the energy.Because the time weak point mainly is the principle by physical reactions in cylinder, oxygen floats and eats softness and all just finish outside.Like this, the friction of fiber just reduces, and has guaranteed the clean and tidy and integrity degree of cloth cover.The suction look even, and quality there is not the cloth of cold dome that further raising is arranged.

Claims (1)

1. the colouring method of a cloth, realize by following steps:

1 ton of embryo cloth is equipped with embryo, binds off again, and removing the work is followed into cold dome machine cold dome processing;

After carrying out cold dome processing in 8-10 minute, stack the cloth car, prick into, stacked 12 hours at 26 ℃ of-28 ℃ of constant temperature with plastic bag;

Begin dyeing again; About 3 hours times spent;

Cleaning, shear after 2 hours, check colors, wash fastness again, need three cylinder water;
