Abstract
The invention discloses a method for dyeing terylene fabric with low temperature. The method comprises the following steps: a pretreating process: raw fabric is put in a first solution for the pretreatment; a dewatering and water entering process: the first solution is discharged and placed into a second solution; a dye adding process: acetate acid and disperse dyes are added in the second solution, wherein the scope of the pH value of the second solution is between 4.5-5.5; a dyeing process, the second solution with added dye is heated to the temperature of 90 DEG C-98 DEG C and insulated for 18-25 minutes; a dewatering process: the insulated second solution is cooled to the temperature of 80 DEG C and the second solution is discharged to finish the dyeing process. The raw fabric forms a dyed finished product. The method for dyeing terylene fabric with low temperature has the advantages that the quasi-chicken pawl imprint on the fabrics can be prevented, spandex breakage on the terylene fabric containing spandex can be avoided, the energy is saved and the cost can be saved.
Description
Technical field
The present invention relates to the fabric treating field, particularly relate to a kind of dacron low temperature dyeing method.
Background technology
Terylene is a kind of important synthetic fiber, is raw material with terephthalic acid (TPA) and ethylene glycol normally, through the polymer PET that polycondensation reaction is processed, the fiber that forms through spinning again.Have intensity height, good luster, durable, performance that natural fabrics such as chemical stability is strong, anti-mould moth hardly match, in textile fabric, occupy an important position.Terylene is as the chemical combination polyester fiber, and its vitrification point is 80 ℃, promptly surpasses more than 80 ℃; The crystallization meeting of polyster fibre is flouring to be changed, and the fine structure of fiber begins to change, and temperature High variation more is just big more; Strand in the macromolecular compound just motion is fast more; It is ternary macromolecular compound to occur: glassy state, elastomeric state, viscous state, and when reaching glassy state and elastomeric state, dye groups just can at high temperature immerse terylene strand gap actively; Terylene absorbs many more to dyestuff, the temperature that needs is just high more.Usually need be heated to 130 ℃ to dyeing terylene in the prior art; Though high temperature is better to the last chromatic effect of terylene; But its fibre structure to terylene has caused certain injury; The dyeing back is prone to form the trace seal of similar shank on lining, simultaneously for the polyester fabric that contains spandex, high temperature can make the spandex fracture.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of dacron low-temperature dyeing method, can prevent that lining from forming the trace seal of similar shank, can prevent disconnected spandex, energy saving and cost lowering to the polyester fabric that contains spandex.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of dacron low-temperature dyeing method is provided, and concrete steps comprise:
(100), pre-treatment: grey cloth is gone into the first road body lotion and is carried out pre-treatment;
(200), draining entry: the first road body lotion is discharged, put into the second road body lotion;
(300), add dyestuff: in the said second road body lotion, add glacial acetic acid and DISPERSE DYES, the PH scope of the said second road body lotion between 4.5～5.5,
(400), colouring: the second road body lotion that will add dyestuff is heated to 90 ℃～98 ℃ and be incubated 18～25 minutes;
(500), draining: the second road body lotion after the above-mentioned insulation is cooled to 80 ℃, the second road body lotion is discharged, accomplish dyeing process, grey cloth forms the colouring finished product.
In preferred embodiment of the present invention, said grey cloth is full polyester fabric or polyester cotton blending lining grey cloth.
In preferred embodiment of the present invention, said grey cloth is the blended yarn woven fabric grey cloth of spandex and terylene.
In preferred embodiment of the present invention, said pre-treatment step comprises: earlier the first road body lotion is heated to 60 ℃, adds bleeding agent then, grey cloth is gone into the said first road body lotion again, then in the first road body lotion, adds to boil and floats auxiliary agent: alkali and H
2O
2, again the first road body lotion that floats auxiliary agent being boiled in adding and be heated to 98 ℃ and be incubated 30 minutes, the first road body lotion after will being incubated at last is cooled to 80 ℃.
In preferred embodiment of the present invention, in the said colouring step, the second road body lotion that adds dyestuff is heated to 95 ℃ and be incubated 20 minutes.
The invention has the beneficial effects as follows: dacron low-temperature dyeing method of the present invention can prevent that lining from forming the trace seal of similar shank, can prevent disconnected spandex, energy saving and cost lowering to the polyester fabric that contains spandex.
