Abstract
The rapid scouring and bleaching agent for dyeing-printing, boiling and bleaching three-into-one process includes main agent and auxiliary agent, said main agent can individually use AR828 and AR838 or their combination, and its auxiliary agent uses alkali agent NaOH and bleaching agent H2O2. The described AR828 is formed from nonyl phenol polyethenoxy ether (n=10,n=7,n=4), dodecyl polyethenoxy ether phosphate, sodium alkylsulfonate, sodium dodecyl polyglycol sulfonate, ethylene glycol butyl ether, isopropanol and water, and the AR838 is formed from water glass and trifatty alcohol-polyoxyethylene methylsilicane. Said invention is simple in composition, convenient for use, does not pollute environment, and is used to treat cotton, artificial cotton and its blended grey fabric at above 95 deg.C for 2-8 min. its whiteness can be up to above 78, and the cotton shell can be completely removed.
Description
The present invention relates in the textile printing and dyeing production fabric be carried out the scouring and bleaching agent for grey fabric that used printing and dyeing pre-treatment is used in destarch, boiling-off, the three-in-one short-flow pre-treating process of bleaching.Be applicable to cotton, artificial cotton and BLENDED FABRIC thereof.
Though at present short-flow pre-treating process changes the tradition three bath methods of moving back, boil, float into single bath process or two bath methods from the eighties, and worked out the supporting scouring and bleaching agent that to spin all grand product A R750 of scientific ﹠ technical corporation be representative with China; But because the rate of sizing of pure cotton woven fabric is higher, thereby can only increase alkali number in the bath, hydrogen peroxide content, under 98～100 ℃ of conditions, still need handle 40～90min, just can reach effect preferably thereafter.In recent years, someone has had new research on the shortening processing time, just proposed a kind of quick scouring and bleaching agent auxiliary agent in example No. 95110969.3 patent applications of China " a kind of fast bleaching agent aid for grey cloth and uses thereof ", it is made up of emulsifying agent, surfactant, builder and anti flocculant basically; Can a step finish operations such as grey cloth destarch, boiling-off, bleaching, handle 2～8min more than 95 ℃; Obtain the base cloth whiteness more than 76, capillary effect is more than 8cm, and boll hull goes only.More or less there is following shortcoming in above-mentioned grey cloth pretreatment technology: it is undesirable that effect is floated in refining, and only more than 8cm, this dye penetration to grey cloth is undesirable for the capillary effect of grey cloth; The builder of one of its constituent, it is the phosphorus-containing detergent based on sodium phosphate trimer, because phosphorous thing can make waters aggravation eutrophication and the severe contamination rivers and lakes, now be decided to be as unfavorable environment-friendly products by some developed country and limited the use of or forbidden thing; Another constituent anti flocculant is chosen to be urea or carboxymethyl cellulose is a raw material, and its function is not obvious, and fully available contained surfactant part replaces, thereby can reduce cost.
The objective of the invention is to develop that a kind of to move back, refine, float effect obvious, constituent is simple and free from environmental pollution, and is easy to use, and the fabric that the scope of application is extensive moves back, refines, floats the scouring and bleaching agent of three-in-one printing and dyeing pre-treatment.
The fabric printing pretreating reagent that the present invention proposes comprises host and assistant agent two parts, it is characterized in that host partly is used in combination polyoxyethylene mixed liquor A R828 and bleach stable liquid AR838, and assistant agent partly comprises NaOH, hydrogen peroxide and water.
The constituent of described AR828 is:
Polyoxyethylene nonylphenol ether 10,0%n,=10 24～40%
Polyoxyethylene nonylphenol ether 1,00%,n=7 2～6%
Polyoxyethylene nonylphenol ether 1,00%,n=4 2～6%
Lauryl alcohol polyoxyethylene ether phosphate 6～10%
Sodium alkyl sulfonate 6～12%
Dodecyl sodium polyethanol sulfonate 4～6%
Butyl glycol ether 2～4%
Isopropyl alcohol 4～6%
Water 50～10%
The constituent of described AR838 is:
Waterglass 80～90%
Three aliphatic alcohol polyethenoxy methyl-monosilanes 10～20%
Two kinds of hosts of AR828, AR838 proportion in the moving back of fabric, refining, bleaching-bathing method pretreating reagent integral body is respectively 1～4% and 0～2% during processing, forms on the thickness of processed object and raw material and decides.Alkaline agent is selected NaOH for use in the assistant agent, floats agent and selects hydrogen peroxide (hydrogen peroxide) for use, and both are used in combination, and they move back at fabric, proportion is respectively 0.5～8% and 0.5～4% in the short process pretreatment agent of refining, the bleaching-bathing method integral body.
Advantage of the present invention is when adopting above-mentioned compound preparation pre-treatment scouring and bleaching agent to shape fabric pretreatment, only need to press grey cloth raw material variety and thickness tightness degree, suitably adjust each component ratio, can be in 2～8min on same unit a step finish destarch, boiling-off, bleaching process, shortened greatly and refined the time of floating operation, saved the energy and reduced investment.Handle the back fabric whiteness and still keep more than 78, capillary effect is more than 10, and boll hull goes only, and is all more obvious than above-mentioned prior art treatment effect.And because the phosphorus-containing detergent that the present invention does not adopt environmental protection aspect forbidding or limits the use of, and kinds of surface activating agent characteristics have separately been made full use of, compoundly be mixed with a kind of pre-treatment scouring and bleaching agent that contains the special fast infiltration function of a small amount of solvent (isopropyl alcohol, butyl glycol ether), make it within one minute, reach and efficiently to float the refining effect fast to the fabric each several part by rapid permeability; Be to improve whiteness and adopt and add low amounts of water glass, but do not adopt urea etc. to make anticoagulant, utilize the characteristics of original surface activating agent own,, both kept whiteness, prevent that again the silicon dirt from producing, and saved cost calcium magnesium silicate salt high degree of dispersion.
