Description
Technical field
The present invention relates to a kind of modified nylon fabric, relate in particular to a kind of chitin modified arrangement nylon fabric and manufacture method thereof.
Background technology
The fabric of chitin modified arrangement known in the art mainly contains COTTON FABRIC, because shitosan is a kind of polysaccharide, has great amount of hydroxy group and amino, and is similar with the cellulose composition of cotton fiber, the two easy combination.And polyamide fibre does not have hydroxyl, and amido link is only arranged, and is difficult to combination with shitosan, can only rely on chemical reaction, allows chitosan graft to nylon fibre.
The kind of polyamide fibre is a lot, and polyamide fibre 6, polyamide fibre 66, polyamide fibre 11, polyamide fibre 610 are arranged, wherein most importantly polyamide fibre 66 and polyamide fibre 6.The character of various polyamide fibres is incomplete same, and common characteristics are that the acid amides chain is arranged on the macromolecular main chain, can adsorbed water molecule, can form crystalline texture, and anti-wear performance is very good, all is good clothing fiber.
Shitosan is the product of de-acetyl chitin, can be dissolved in the aqueous solution of low acidity, and because it contains free amine group, can be in conjunction with acid molecule, so have many special physicochemical properties, biological function.Shitosan is the most important derivative of chitin, is that the chitin deacetylase degree reaches the product more than 70%, also is the unique natural alkalescence sugar of finding up to now, has avirulence, biodegradable, good characteristics such as biocompatibility.So shitosan has shown high using value and development prospect widely, is a kind of novel multifunctional fabric finishing agent, be widely used at aspects such as printing and dyeing, anti-wrinkle, felt proofing, antibiotic and fibrous filter.
Shitosan has been successfully used in the modification COTTON FABRIC, and is for it provides biocidal property, crease-resistant or help and dye.The property that can give equally the polyamide fibre shitosan with chitin modified arrangement polyamide fibre, but modification is relatively difficulty, at home rarely seen report.
Summary of the invention
The purpose of this invention is to provide a kind of chitin modified arrangement nylon fabric and manufacture method thereof, the surface of nylon fabric performance after the modification improves, and have simultaneously the functions such as antibacterial, antistatic, and this method of modifying is simple, and is with low cost.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of chitosan modified nylon fabric wherein is grafted with the shitosan of mass content 0.1% ~ 2% on this kind nylon fabric.
A kind of manufacture method of chitosan modified nylon fabric may further comprise the steps:
(1) take by weighing nylon fabric, impregnated in the polyamide fibre aqueous oxidizing agent solution, bath raio 1:10 ~ 1:40, heating water bath stirs;
(2) shitosan is dissolved in 1% ~ 6% the glacial acetic acid, stirs and make its dissolving form saturated solution;
(3) take by weighing the shitosan oxidant and add in step (2) the shitosan saturated solution, stir and evenly mix heating water bath;
(4) shitosan mixed liquor adding in the step (3) is impregnated with in the polyamide fibre oxidizing agent solution of nylon fabric, the adding volume is 0.5 ~ 3 times of polyamide fibre oxidizing agent solution, and heating water bath stirs;
(5) nylon fabric that takes out after putting in order is soaped, and dries to get final product.
Described polyamide fibre oxidant is at least a in persulfate, perborate, the hydrogen peroxide, and preferred persulfate is potassium peroxydisulfate, and preferred perborate is sodium perborate.
Described shitosan oxidant is potassium peroxydisulfate.
The concentration of polyamide fibre oxidant is 1 ~ 50mmol/L in the polyamide fibre aqueous oxidizing agent solution of described step (1).
The concentration of polyamide fibre oxidant is 2 ~ 10mmol/L in the polyamide fibre aqueous oxidizing agent solution of described step (1).
The concentration of shitosan oxidant is 2 ~ 10mmol/L in the shitosan mixed liquor of described step (3).
The water bath heating temperature of described step (1), (3) and (4) is 30 ~ 70 ℃, and wherein the preferred heating-up temperature of step (1) and step (4) is 50 ℃, and the preferred heating-up temperature of step (3) is 55 ℃.
The heating water bath time in described step (1) and the step (3) is 60-250min.
The heating water bath time in the described step (4) is 200 ~ 300min.
The preferred concentration of glacial acetic acid is 3% in the described step (2).
Bath raio in the said method refers to the ratio of fabric weight and solution weight, and bath of preference is than being 1:15 ~ 1:20 in the step (1).
In order to increase the polyamide fibre oxidative degradation degree in the step (1), thereby but increase the active site of the grafted chitosan molecule that forms on the polyamide fibre molecule, can repeatedly add oxidant, heating water bath oxidation by substep.
The invention has the beneficial effects as follows:
The present invention adopts the oxidant respectively large molecule of oxidative degradation polyamide fibre and chitosan molecule, make on both molecule and produced respectively the reactivity point, thereby so that the easier grafting of shitosan be attached on the polyamide fibre molecule.Test discovery by the present invention, when chitosan graft reaches the 0.1%(mass fraction to polyamide fibre) time, nylon fabric is more smooth elegant, does not crease easily, and is conducive to dyeing, also has simultaneously the effects such as biocidal property, antistatic.And by the nylon fabric after the inventive method modification, the chitosan mass mark of grafting on the fabric can reach more than 1.0% substantially, and high energy reaches 2.0%, and this is so that nylon fabric has had a lot of performances of shitosan, and fabric property is better improved.The inventive method is simple simultaneously, and because raw material is conventional the use, cost is lower.
