Abstract

The invention relates to a rot resistant finishing agent special for textiles. The rot resistant finishing agent has the characteristics of mold prevention and antibiosis, anti-static electricity, no toxicity and irritation, and good chemical compatibility. The rot resistant finishing agent is mainly applied to the after-finishing process of the textiles so that the textiles have the effects of mold prevention and rot resistance; simultaneously, the rot resistant finishing agent also is applicable to anti-mildew and rot resistant finishing of products such as softening agents, coatings, waterproofing agents and adhesives.

Description

Textiles special anti-corrosion finishing agent

technical fieldthe present invention relates to a kind of textiles special anti-corrosion finishing agent, its active ingredient is water soluble chitosan, MIT (MIT), lysozyme, protective agent PT3, isopropyl alcohol and polyethylene glycol, through special process, is prepared from.Be mainly used in the postfinishing process of textiles, make textiles there is mildew-resistant, corrosion-resistant effect; Also be applicable to the products such as softener, coating, waterproofing agent, adhesive simultaneously anti-ly go mouldy, anti-corrupt arrangement.

background technologyin daily life, we can inevitably touch various pathogenic bacteria, and the textiles ground of the good existence of these microorganisms just.Along with the enhancing of health care consciousness, people will more and more pay attention to the anti-microbial property of textiles.The textile finishing technology of any inhibition or kill microorganisms all can be described as antimicrobial finish, and wherein rot resistant finish is mainly to avoid the growth of mould to destroy textiles.Existing preservative agent is of a great variety on the market, but majority exists chemical toxicity large, the shortcomings such as irritant smell.All there is the hidden danger of going mouldy in outdoor textile product, the conventional textiles of wet environment, is therefore necessary to invent a kind of textiles special anti-corrosion finishing agent, can either effectively prevent from going mouldy, and has again safety non-toxic, non-stimulated environmental protection performance.

summary of the inventionthe invention provides a kind of textiles special anti-corrosion finishing agent, it is rationally composite that main points are to select multiple antibiotic antiseptic and textile finish to carry out, by blending, emulsification, the operation such as mix and make.The formula following (component and percentage by weight %) that the present invention selects: water soluble chitosan 2-5, MIT (MIT) 0.5-1, lysozyme 0.2-0.8; protective agent PT3 0.5-1.5; isopropyl alcohol 2-3, polyethylene glycol 0.5-1, soft water adds to 100.

Shitosan is alkaline polysaccharide unique in natural polysaccharide, has good biocompatibility and degradability, has the function of collagen and string simultaneously, substantially without antigen and sensitization, skin is not stimulated, safe, has no adverse reaction.Its antibacterial principle is that the negative electrical charge on its positive charge and microbial cell film surface produces association, has changed the permeability of microbial cell film, thereby causes that microbial cell is dead.In addition, because shitosan has fine small structure, there is capillarity, can distribute rapidly the sweat of absorption, make bacterium be difficult for adhering to and growing, thereby strengthened antibacterial effect.

MIT bactericidal property has broad spectrum activity, can kill algae, fungi, bacterium, mucus is had to penetration simultaneously; The harmful bacteria such as black-koji mould, Penicillium notatum, trichophyton gypseum, Candida albicans, acrothesium floccosum completely, non-stimulated to skin, without allergic reaction, nontoxic to human body, be applicable to the fabrics such as cotton textiles, hair, fiber crops, polyester-cotton blend, chemical fibre anti-ly go mouldy, anti-corrupt arrangement.

Lysozyme is a kind of nontoxic protein matter, can optionally decompose the cell membrane of microorganism, thereby in cell, the pathogen after engulfing is played to the breeding that destruction suppresses microorganism, especially gram-positive bacterium is had to stronger bacteriolysis.

Protective agent PT3 is a kind of multi-hydroxy compound; after dressing liquid adds; make energy and cotton fiber generation condensation under its condition of curing at high temperature, produce long, hyperbranched interlinkage structure, can improve to a certain extent fracture strength and the TEAR STRENGTH of cotton fiber after arranging.

Isopropyl alcohol is organic solvent, and each component is fully dissolved, and plays a role; Polyethylene glycol can improve the viscosity of this rot resistant finish agent as thickener, has lubricating function; Also as polymeric antistatic agent, there is the antistatic effect lasting period long, fast, little to the relative humidity dependence of the air advantage of performance antistatic property simultaneously.

Preparation technology of the present invention is:

(1) by proportioning, described component water soluble chitosan, MIT (MIT), isopropyl alcohol are mixed in soft water solution, in retort, stir and be transparence;

(2) by proportioning, described component protective agent PT3 and polyethylene glycol are added in retort, carry out emulsion reaction 20min;

(3) question response liquid cooling, to 30-40 ℃, adds lysozyme, after soft water adds to 100, stirs;

(4) detect qualified after, packing is preserved.

The invention has the beneficial effects as follows: the composite antimicrobial spectrum of having widened of (1) antibiotic antiseptic, has broad spectrum antibacterial performance; (2) fungus-proof antisepsis superior performance is especially effective lastingly for fungi; (3) safe, non-stimulated, nontoxic to people under working concentration; (4) antistatic, make fabric feeling lubricated; (5) cotton, fiber crops, chemical & blended fabric are all had to mildew resistant finish function; (6) chemical compatibility is good, can add in softener, adhesive, coating and bring into play mildew-proof function.
