Description

The special-purpose anti-bacteium deodorization finishing agent of textiles

technical fieldthe present invention relates to the special-purpose anti-bacteium deodorization finishing agent of a kind of textiles, its active ingredient is chitosan, myristyl dimethyl-3-(trimethoxy silane propyl group) ammonium chloride, hexamethylene, the sour sodium of glucose fat, lavender, ethanol, through special process, is prepared from.Mainly in the finishing process of textiles, use, make textiles there is deodorization, antibacterial effect; Also be applicable to smelly eliminating, the antibacterial processing of existing peculiar smell textiles simultaneously.

background technologythe today of progressively improving in living standard, the comfortableness of textiles directly affects people's quality of life, and giving anti-bacterial anti-foul function is the important means that properties of textile improves.The development history of modern anti-bacteium deodorization finishing agent, can trace back to nineteen thirty-five and by G. Domak, be used the military uniform of quaternary ammonium salt processing, to prevent injured soldier's superinfection.On nineteen forty-seven American market, there are the commodity such as diaper, bandage and towel of being processed by quaternary ammonium salt, can prevent baby's ammonia dermatitis disease.The people such as nineteen fifty-two Britain Engel process woollen blanket with softex kw and bed (seats) pads fabric, but because quaternary ammonium salt activity is lower, not water-fastness with soap.After, once once using the efficient germicides such as organic mercury, organotin as the anti-bacteium deodorization finishing agent of textiles.But, because this class efficient germicide is easy to cause, be just eliminated the injury of human body skin soon.Later anti-bacteium deodorization finishing agent always along safety, high-efficiency broad spectrum is antibacterial and the exploitation of the direction of durability.Weaving can be divided into natural, organic and inorganic three major types with antiseptic, and every class antiseptic has pluses and minuses.Organic antiseptic is effective, wide in variety, is a current the most widely used class antiseptic, but has the problems such as non-refractory, poor stability, is difficult to use in synthetic fiber spinning technique; Natural antimicrobial agent has good security conventionally, but its range of application is narrow, and majority has a strong impact on the coloured light of plant; Inorganic antiseptic good heat resistance, but be difficult to obtain durable effect for after-finishing of textile products, and there is the toxicity problem of heavy metal in most of kind.Based on above situation, we think and are necessary to invent the special-purpose anti-bacteium deodorization finishing agent of a kind of textiles.This finishing agent is intended, on the basis of composite multiple broad spectrum antimicrobicide, adding finishing auxiliaries and a little spices, on the one hand the ratio of antibacterial each component is down to minimum, minimum is down in side effect, antibacterial action performance, to maximum, by particular perfume expelling worms and preventing moth, improves fabric smell on the other hand.

summary of the inventionit is rationally composite that main points of the present invention are to select multiple broad spectrum antimicrobicide, finishing auxiliaries and spices to carry out, the special-purpose anti-bacteium deodorization finishing agent of a kind of textiles forming through emulsion reaction.

The formula following (component and percentage by weight %) that the present invention selects: chitosan 5-15, myristyl dimethyl-3-(trimethoxy silane propyl group) ammonium chloride 2-4, hexamethylene 1-3, the sour sodium 1-2 of glucose fat, lavender 0.2-0.5, ethanol 2-6, soft water adds to 100.

Chitosan 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.

Myristyl dimethyl-3-(trimethoxy silane propyl group) ammonium chloride belongs to organosilicon quaternary ammonium salt class, its Antibacterial Mechanism is CATION in mat quaternary ammonium salt molecule, by the anionic site on Electrostatic Absorption microbial cell surface, with hydrophobic interaction, make intracellular matter sew out, make microbial respiratory function stop and being killed.Such material, in performance high-efficiency antimicrobial performance, also has good washability.Because the trimethoxy silane propyl group of ining succession has alkane silicon contingency, form silanol base after meeting water, under drying condition, can with fiber on hydroxyl generation dehydration condensation, be attached on fabric chemistry, so improved the washability of antibiotic fabric.

Hexamethylene is a kind of environment-friendly multipurpose new polymers, ability Escherichia coli, staphylococcus aureus, fungi etc. to extremely strong kill bacteria, wide spectrum, efficient, antibacterial for a long time, have colourless, odorless, to skin nonirritant, avirulence, non-corrosive feature.Its antibacterial action is mainly by solubilizing lipids, changes the permeability of bacterial cell membrane, makes endobacillary metabolism generation obstacle and antibacterial.

Lavender, because its effect is maximum, has the good reputation of " fragrant medicinal herbs ", is called as " after vanilla ".Its pure and fresh gracefulness of fragrance, character is gentle, has the mothproof function of antibacterial, worm-expelling, is particularly used for, except roach is except mite, improving fabric smell.

The sour sodium of glucose fat extracts from natural plants, and nonirritant plays thickening in solution; Ethanol is a kind of good solvent, can dissolve inorganic matter, also can dissolved organic matter, so conventional its dissolves industrial chemicals, it is fully dissolved, and play a role.
