Abstract
The invention discloses a novel real silk fabric polishing finishing agent and a use method thereof, and belongs to the field of application of dyeing additives. The novel real silk fabric polishing finishing agent is prepared from protease in a compounding manner, epoxy chloropropane and sodium hypophosphite are added to polish and finish a real silk fabric, the bath ratio is 1:(15-20), the use amount of the novel real silk fabric polishing finishing agent is 0.7-1.2%, the pH value is 5.0-7.5, the temperature range is 40-65 DEG C, and the finishing time is 30-45 minutes. The novel real silk fabric polishing finishing agent disclosed by the invention is efficient, low in environment requirement, and good in ecological benefit and economic benefit.
Description
Technical field:
The invention belongs to dyeing assistant Application Areas, be specifically related to the agent of a kind of novel silk fabrics polished finish and using method thereof.
Background technology:
Silk broadcloth is the protein fibre of pure natural, has the gloss of soft floridity, plentiful smooth feel, and outward appearance elegant is merrily and lightheartedly elegant, also has moisture absorption simultaneously and breathes freely and wear the interior quality of comfortable skin care.Simultaneously also because it is the protein fibre of pure natural, so require harsh in the process of protease polished finish for Degree of Enzymatic Hydrolysis, enzymolysis excessively directly causes the damage of silk broadcloth product.
Protease is mainly applicable to process thicker and the more coarse silk broadcloth thing of surface ratio as polished finish agent, the filoplume of the fabric face after process and silk gum etc. are almost removed, not only obtain smooth and smooth outward appearance, and color and luster and feel all improve, product quality is tending towards superior.But protease is as biological enzyme formulation, it has the speciality of mildness, and its operating environment requirements to enzyme preparation is harsh, and this have impact on its process efficiency and economic benefit.
Chinese invention patent CN101824753A discloses a kind of method for polishing and finishing of soyabean protein fabric, in order to reduce the use of soyabean protein fabric chemicals in the process arranged, protease is utilized to carry out polishing to fabric, polissoir adopts rope dyeing machine; bath raio is 1: 10-1: 15; the consumption of protease is at 1.5-2.5%wt, and adopt segmentation addition method, pH value is 6.0-7.5; temperature 45-55 DEG C; the time, protease polished finish effect was lasting at 30-45min, and the prolonged washing of fabric energy; smooth surface; not easily balling-up is pollution-free, comfortable and easy to wear.But the method technique is remarkable not for silk fabric effect.
Summary of the invention:
The object of the invention is to for the deficiencies in the prior art, provide the agent of a kind of novel silk fabrics polished finish and using method thereof, this polished finish agent is efficient and low to environmental requirement, has good ecological benefits and economic benefit.
The invention provides following technical scheme:
A kind of novel silk fabrics polished finish agent, comprises the component of following parts by weight:
Pepsin 0.5-0.7 part, papain 3-8 part, neutral proteinase 1-1.5 part, alkali protease 0.7-1 part, epoxychloropropane 0.01-0.02 part, inferior sodium phosphate 0.05-0.1 part.
Preferably, the component of following parts by weight is comprised:
Pepsin 0.5-0.6 part, papain 5.5-8 part, neutral proteinase 1.2-1.5 part, alkali protease 0.7-0.9 part, epoxychloropropane 0.01-0.02 part, inferior sodium phosphate 0.05-0.08 part.
The using method of a kind of novel silk fabrics polished finish agent, the use amount of silk fabrics polished finish agent is at 0.7-1.2%, the silk fabrics polished finish agent of 70-80% quality is added before polished finish process starts, continue to add the agent of 20-30% quality when arranging process half the time, the silk fabrics polished finish agent adding 30% quality is continued; bath raio is 1:15-20; pH value is 5.0-7.5; temperature range is 40-65 DEG C, and finishing time is 30-50 minute when arranging process half the time.
Preferably, the use amount of described silk fabrics polished finish agent is at 0.7-1.0%, before polished finish process starting, adding the silk fabrics polished finish agent of 70% quality, continuing when arranging process half the time the silk fabrics polished finish agent adding 30% quality.
Preferably, described bath raio is 1:20, and pH value is 5.0-7.0, and temperature range is 45-65 DEG C, and finishing time is 40-50 minute.
Cell secretes at the bottom of pepsin reason stomach, under pH1.5-5.0 condition, is activated into pepsin, is peptide by breaks down proteins, is generally used as the Proteinaceous food for the treatment of food too much caused indigestion at present.
Papain is all widely used in weaving cosmetics etc.; Neutral proteinase is extracted through fermentation by bacillus subtilis and obtains, and belongs to a kind of restriction endonuclease, can be used for various proteolysis process.Under uniform temperature, pH value, macro-molecular protein can be hydrolyzed to the products such as amino acid by this product.The hydrolysis of animal/vegetable protein can be widely used in, produce HAP and HVP producing senior flavouring and food enrichment, can be used for the processing such as leather depilation, softening, wool silk scouring in addition.
Alkali protease, also known as serine protease.It not only can hydrolysising peptide key, also has hydrolysis amido link, ester bond and transesterification and turns the function of peptide.Due to the selectivity of enzyme, it to proteolysis, can only can not act on the material such as starch, fat.
Ortho phosphorous acid sodium catalyst, stabilizing agent, prepare polyamide macromolecule polyamides thing, accelerates chemical reaction, be also widely used in textiles finishing field.Epoxychloropropane main application is for epoxy resin processed, is also a kind of stabilizing agent and chemical intermediate of oxygen carrier, the main raw material of epoxy radicals and phenoxy resin; Manufacture glycerine; Slaking propylene-based rubber; The solvent of cellulose esters and ether; The high wet strength resin of paper industry.Poisonous, belong to moderate toxicity, zoopery proves there is potential carcinogenesis, should avoid Long Term Contact.By composite for various protease rear interpolation epoxychloropropane and inferior sodium phosphate in the present invention, the functional activity of various protease can be improved, reduce reaction activity, improve reaction efficiency, and then increase economic efficiency, reduce the use of enzyme preparation.
Beneficial effect of the present invention:
1. polished finish agent high-efficiency environment friendly of the present invention, has higher economic benefit.
2. polished finish agent of the present invention is composite by multiple proteins, has good adaptive capacity to environment, low to environmental requirement, has good ecological benefits.
3. the using method of polished finish agent of the present invention is easy, has good economic benefit and ecological benefits.
