Description
Technical field
The present invention relates to a kind of modification 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 combine 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 characteristic is that the acid amides chain is all 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 of it contains free amine group, can be in conjunction with acid molecule, so have many special physicochemical character, 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 characteristics such as avirulence, biodegradable, excellent biological compatibility.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 success be used for the modification finishing of cotton textiles, for it provides biocidal property, crease-resistant or help and dye.The property that can give the polyamide fibre shitosan equally with chitin modified arrangement polyamide fibre, but the modification arrangement is the comparison difficulty, rarely seen at home 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 functions such as antibacterial, antistatic simultaneously, 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 chitin 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 chitin 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, water-bath adds thermal agitation;
(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, stirring and evenly mixing, water-bath heating;
(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 water-bath adds thermal agitation;
(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 a potassium peroxydisulfate, and preferred perborate is a sodium perborate.
Described shitosan oxidant is a potassium peroxydisulfate.
