Abstract
The invention aims to provides a method for preparing a cleaning agent for reductive cleaning of fabrics with high fastness to soaping and high sublimation fastness, aiming at overcoming the shortcomings of low or unstable fastness to soaping and sublimation fastness and unstable three-proofings function and water washing resistance of dacron fabrics caused by unclean flooding on the surface of the fabrics cleaned by a reductive cleaner in the prior art. According to the method, 1.5+/-0.5 g of caustic soda having the concentration of 30%, 1.0+/-0.5 g of thiourea dioxide, 1.0+/-0.5 g of ethylene oxide condensate and 1.0+/-0.5 g of alkyl sodium sulfonate are added to each liter of water by mass. The method comprises the following steps of: adding the caustic soda after the thiourea dioxide is added to water and completely dissolved under stirring and then orderly adding the ethylene oxide condensate and the alkyl sodium sulfonate, and then evenly mixing all the materials, thereby obtaining the reductive cleaning agent. Dacron fiber dyed fabrics treated by the reductive cleaning agent obtained by the method are characterized in that flooding and oligomers are removed clearly; as a result, the fabrics can have high fastness to soaping and high sublimation fastness.
Description
Technical field
The present invention relates to the preparation method of high fastness to soaping and high sublimation fastness fabric reduction cleaner.
Background technology
Polyester piece good Chinese people are commonly called as " dacron ".Having many uses of terylene, in a large number for the manufacture of clothing fabric and mechanicals.Terylene has extremely good setting performance.Spun polyester thread or fabric generate after setting flat very, fluffy form or rivel etc., in use through repeatedly washing, still can be prolonged constant, in addition it have durable, good springiness, not yielding, corrosion-resistant, insulation, well-pressed, easily wash, the feature such as quick-drying, by people are liked.At present, polyester piece good is just towards the future development of naturalization of synthon such as simulate wool, imitative silk, imitative fiber crops, imitation buckskin.Be widely used on outdoor activity and easy suit.And on outdoor activity and easy suit, conventionally require to there is higher fastness to soaping and sublimation fastness and refuse water, refuse oil, refuse dirty NBC protective performance.
At present, fabrics of polyester mainly adopts disperse dyeing process, its dyeing course is as follows: under High Temperature High Pressure, dispersed dye dissolve, and--fiber surface absorption dispersed dye--dispersed dye spread in fiber--dispersed dye are penetrated into polyster fibre noncrystalline domain, realize fiber staining, then with reduction cleaner, the fabric through disperse dyeing is carried out to reduction clearing, wash away PET fiber surface loose colour.Main alkaline reduction clean-out system and the acidic reduction cleaner of adopting cleans fabric at present, and then washes.The composition of alkaline reduction clean-out system is the aqueous solution of caustic soda, thiourea peroxide, dispersion agent, soaping agent.While adopting the alkaline reduction clean-out system cleaning polyester piece good of above-mentioned formula, it is unclean that loose colour to polyester piece good surface and oligopolymer are cleared up, make the colour fastness of fabric undesirable, therefore soaping fastness and sublimation fastness after dyeing are general, only 3 grades of soaping fastnesses, 3 grades of sublimation fastness conventionally.And three anti-wash durabilities only have 5-10 time after three-prevention finishing.
Summary of the invention
The present invention seeks to for reduction cleaner cleaning fabric surface loose colour in prior art unclean, make polyester piece good fastness to soaping and sublimation fastness not high or unstable, and the unsettled deficiency of three anti-function wash durabilities, provides a kind of high fastness to soaping and high sub limation fastness polyester piece good also to clean the preparation method of Ji.
The preparation method of high fastness to soaping and high sub limation fastness polyester piece good reduction cleaner, described reduction cleaner is as follows by the quality proportioning adding in every premium on currency: caustic soda 1.5 ± 0.5g, thiourea peroxide 1.0 ± 0.5g, ethylene oxide condensate 1.0 ± 0.5g, alkyl sodium sulfonate 1.0 ± 0.5g that concentration is 30%, under room temperature, in water, add thiourea peroxide to be stirred to after dissolving completely, add again caustic soda, stir, then add successively ethylene oxide condensate, alkyl sodium sulfonate to mix, make reduction cleaner.
When the reduction that adopts the inventive method to make washes down lotion-treated polyester piece good, as the coated PET fiber surface of ethylene oxide condensate of dispersion agent, the dispersed dye that absorption does not enter noncrystalline domain are completely loose colour, and loose colour is distributed in treatment solution, stops and be reduced the dispersed dye of washing off again by i.e. counter being stained with of fabrics of polyester surface adsorption; Simultaneously, utilize the oligopolymer of its surfactivity in fabrics of polyester to be combined at the swelling lower dispersion agent of alkali, the tensio-active agent that is adsorbed onto fabric face during by dyeing is separated in reduction dilution, like this, the oligopolymer that is coated on the loose colour of fiber surface and be penetrated in fiber is easy to be rinsed out by the hot water wash of carrying out subsequently, so, very clean through clean-out system of the present invention polyster fibre dyeing textile loose colour after treatment and oligopolymer removal, can make fabric reach higher colour fastness.The three anti-heat setting types that are simultaneously beneficial to below arrange.After this clean-out system is processed, refuse water, refuse oil, to refuse dirty NBC protective performance water-wash resistance lasting, can reach 10～20 times, not only have high fastness to soaping and high sub limation fastness, and technology stability is good, stay in grade.
Embodiment
Below in conjunction with embodiment, the present invention is conducted further description:
