Abstract
The present invention relates to an antibacterial cotton fiber or cotton fabric, and a preparation method, which is a cotton fiber or a cotton fabric converting hydroxyl groups into carboxylic methyl zinc. The method of the present invention comprises the following steps that alkali treatment is carried out on the cotton fiber or fabric in aqueous alkali, and alkali cellulose is formed; then, carboxymethyl groups are linked on the surface of the fiber through a carboxymethylation reaction; the carboxyl and zinc ions react to generate carboxylic acid zinc salts, and thus, the cotton products which contain zinc and have antibacterial function are produced. The method of the present invention is applicable to other cellulose fibers and products.
Description
Technical field:
The present invention relates to a kind of in antibiotic cotton fiber or COTTON FABRIC and preparation method.System by cotton fiber or COTTON FABRIC carboxy methylation after with zinc ion reaction after make, have antibacterial action.
Background technology:
COTTON FABRIC is output height, moderate cost, comfortable and easy to wear, is subjected to deeply that people's extensively like natural fabric.Along with growth in the living standard, people are also more and more higher to the requirement of clothes.Except to the outward appearance of clothes, comfortableness etc., various requirement has been proposed also.Antibiotic requirement is exactly one of them.
At the antibiotic method aspect the synthetic fiber: what have becomes in the process at fibre forming, adds antibiotic medicine in the raw material of fiber, carries out spinning moulding processing, obtains anti-bacterial fibre.As Chinese patent 00134150.2 is with the dispersant coupling agent, antioxidant, and antibiotic merit powder and polyamide fibre pellet carry out spinning after mixing, and are polyamide fibre-6 anti-bacterial fibre; Chinese patent 00107688.4 is for containing the core-skin composite spinning fiber of nanometer-level silver powder; The anti-bacterial fibre that Chinese patent 00100636.3 gets for the viscose glue slurries spinning of being mixed with property chitosan derivatives.
For the antibacterial functions of finished fiber and fabric, the method for carrying out chemical surface treatment and coating is arranged.Coating process be antiseptic with after adhesive mixes, fiber or fabric face are applied, this method can directly influence the feel of fabric.As Chinese patent 96200511.8 for being the antimicrobial layer of carrier with the binding agent.Chemical surface treatment needs fiber itself that the group that can react is arranged.The itrile group that can carry out chemical reaction is easily arranged, so acrylic fibers commonly used carry out antibacterial modified on the acrylic fibers.As Chinese patent 01129949.5 is the grafting of adopting on polyacrylonitrile fibre, and processes such as the dipping in hydrazine hydrate liquid, amidrazone structuring, basic hydrolysis prepare the method for New-type wide-spectrum anti-bacterial fibre.Chinese patent 87100231 is to form fiber in conjunction with copper ion and aminated compounds by acrylic fabric through chemical treatment.Chinese patent 97220754.6 and 97220753.8AB anti-bacteria cloth also are to form the fabric product that obtains in conjunction with copper ion and aminated compounds through chemical treatment by acrylic fabric.Chinese patent 01129945.2 utilizes polyacrylonitrile grafting on natural sisal fiber, reaches further processes such as the dipping in hydrazine hydrate liquid, amidrazone structuring, basic hydrolysis.
Other also have Chinese patent 02130694.X for add quaternary ammonium salt, halogenated amine and macromolecular fibre reaction in reactor; Chinese patent 00121287.7 discloses a kind of nanometer silver anti-bacteria cloth, is included between the fiber of cloth and on the fiber and is attached with the silver particle that particle diameter is 1～100 nanometer; Chinese patent 03128040.4 and 00124854.5 all is to utilize Nano Silver attached to intrastitial method.And be the method for coated antibacterials and absorption silver particles at present basically for the antibacterial treatment of purified cotton yarns and fabric.
The present invention is a kind of method that zinc atom prepares sterilizing fiber or fabric that connects on cotton fiber and fabric.Well-known zinc atom has bactericidal property, and medical zinc oxide rubber glue utilizes the sterilizing ability of zinc exactly.The present invention a kind ofly is connected to method on cotton fiber or the fabric to the zinc atom with antibacterial ability by chemical bond.The cotton products that obtain have so not only had the sterilization antibacterial functions, and have kept the true qualities of natural cotton.
Summary of the invention:
The purpose of this invention is to provide a kind of antibiotic cotton products, as fiber or fabric.
Purpose of the present invention also provides a kind of above-mentioned antibiotic cotton fiber or process for making such fabric.
Antibiotic cotton fiber provided by the invention or fabric are a kind of cotton fiber or fabrics that contains carboxymethyl zinc.
The principle of patent of the present invention is to utilize the reactable of the hydroxyl on the cotton fiber inner cellulose molecule, carry out carboxymethylation reaction earlier on fibriilar top layer, on fiber, introduce hydroxy-acid group, and then react, obtain containing the cotton fiber or the fabric of zinc atom with zinc salt solution.The inventive method is applicable to the processing of other cellulose fibres and goods.
Main technique of the present invention can be with representing as accompanying drawing 1.
The present invention includes the alkali treatment in aqueous slkali of cotton fiber or fabric, form alkali cellulose, with carboxy methylation agent reaction, connect carboxymethyl group at fiber surface again, carboxyl and zinc ion are reacted into salts of carboxylic acids then.The key problem in technology of this method is the control to the carboxy methylation degree, carboxymethylatedly can make excessively that fibre strength weakens, feel degenerates; The deficiency of carboxy methylation degree, in conjunction with zinc ion few, antibiotic timeliness is shorter.
The aqueous slkali of described alkali treatment is the aqueous solution of NaOH or potassium hydroxide.Its concentration expressed in percentage by weight is 2%-20%.
Described carboxy methylation agent is the aqueous solution of chloracetic acid salt, and its salt is the salt of potassium or sodium or ammonium, and the concentration expressed in percentage by weight of its aqueous solution is 1%-12%
Described zinc ion is to be provided by zinc chloride, zinc sulfate, zinc nitrate, zinc acetate, zinc citrate or zinc gluconate, and the concentration expressed in percentage by weight of its aqueous solution is 0.1%-5%.The weight ratio of cotton fiber or fabric and aqueous slkali is 1: (0.08～0.15).
The technology of alkali treatment is that cotton fiber or fabric are placed in the above-mentioned aqueous slkali, handles 0.1-4 hour under 30-70 ℃ temperature.Extract after the taking-up, squeeze out redundant solution, put into and extract after the carboxy methylation agent is flooded, under 20-80 ℃ temperature, handled 0.1-4 hour.Washing is clean, immerses in the zinc salt solution of normal temperature, handles 1-10 minute, goes out to use the clear water rinsing clean, drying.
Above-mentioned raw materials used among the present invention is the commercially available prod.
Above-mentioned raw materials is required to be mixed with respectively aqueous slkali, carboxy methylation agent solution and zinc solution.All-cotton fabric or fiber, handle then by the technology of above-mentioned narration.Promptly obtain the said cotton goods that contain zinc atom of the present invention.Of the present invention contain zinc fiber and fabric be and handle before fiber or the same color and luster of fabric.Treatment process of the present invention is simple, carries out easily.
