Abstract
The invention discloses a kind of immersion depositions to prepare super-hydrophobic-antibacterial-ultraviolet protection polyester fiber cloth method, lead to nitrogen into N hydroxymethyl acrylamide aqueous solution, heating, the polyester fiber cloth of swelling treatment, the benzole soln of benzoyl peroxide is added, is stirred at reflux graft reaction, takes out, washing, again with methanol is extracted, and drying to constant weight, obtains the polyester fiber cloth of surface grafting polymerization；Into Chitosan powder plus hydrochloric acid solution sufficiently dissolves, it is neutrality, then the mixing of plus nano complex antimicrobials that sodium hydroxide solution is added dropwise under stirring to pH, and aforementioned polyester fiber cloth is impregnated wherein, taking-up is filtered dry surface moisture, air-dries and obtains chitosan-composite nano germicide-polyester fiber cloth；Tetrahydrofuran, hexadecyl trimethoxy silane are mixed, titanium dioxide nano-particle is added, after magnetic agitation, poly- dimethoxysilane, curing agent and antibiotic polyester fiber cloth is added, is taken out after stirring, dry super-hydrophobic-antibacterial-ultraviolet protection polyester fiber cloth.
Description
Technical field
The invention belongs to clothing fibers fields, and in particular to a kind of immersion deposition prepares super-hydrophobic-antibacterial-ultraviolet protection
The method of polyester fiber cloth.
Background technique
Terylene has Gao Mo, high-strength, endurance, corrosion-resistant, thermal stability as the highest product of yield in chemical fibre
The excellent performance such as good, is applied, such as conveyer belt, automobile-used fiber, filtering material in many fields.But due to terylene
Macromolecular is other than both ends respectively contain a hydroxyl and carboxyl, then without other polar groups, and therefore, the bond properties of terylene is very poor.
The method for being used to improve terylene bond properties at present mainly has using double-steeping or multiple dipping, modified single-steeping, changes
Kind sizing compound formula and terylene surface are modified.
Polyester (PET) fiber has many advantages, such as that at low cost, intensity is high, rapid-curing cutback and stable structure, is widely used in clothes, family
The fields such as spinning.Conventional PET fiber does not have the ability for killing germ, and fiber itself is a kind of substance of high surface area, is conducive to
The attachment of microorganism is bred and is propagated.The people of enhancing with to(for) environmental protection, safety etc. consciousness, therefore develop with antibacterial
The PET fiber of performance is of great significance.
Because of its excellent mechanical property and mechanical performance, all playing in fields such as weaving, industry, medical treatment can not replace PET
The effect in generation.However, PET segment is regular, crystallinity is high, lacks polar functional group causes its hygroscopicity, antistatic property very poor.
Therefore, improve these disadvantages, the research for preparing functional polyalkylene ester fiber is extremely important.Currently, the totality of China's dacron product
Level still has certain gap compared with American-European, Japan and Korea S and Taiwan, and domestic terylene is improving differentiation of product rate side
Face also grows a lot space.
In recent years, with the continuous improvement of people's living material level and the development of science and technology, functional requirement of the people to fabric
Fabric higher and higher, that more favor has the complex functions such as automatically cleaning, uvioresistant.
Summary of the invention
The purpose of the present invention is being directed to existing problem, providing a kind of immersion deposition, to prepare super-hydrophobic-antibacterial-ultraviolet
The method for protecting polyester fiber cloth, the polyester fiber cloth according to this method production have excellent antibiotic property, antistatic property, surface
Super-hydrophobicity and ultraviolet protection.
The present invention is achieved by the following technical solutions:
A kind of immersion deposition prepares super-hydrophobic-antibacterial-ultraviolet protection polyester fiber cloth method, which is characterized in that including such as
Lower step:
(1) polyester fiber cloth chemical grafting treated polymeric modification:
It is passed through nitrogen into monomer N hydroxymethyl acrylamide aqueous solution, is warming up to 80-85 DEG C, the terylene that swelling treatment is added is fine
The benzole soln of Wei Bu, initiator benzoyl peroxide after being stirred at reflux graft reaction 2-3h, take out, clear with 90-95 DEG C of distilled water
It washes 2-3 times, again with methanol Soxhlet extraction 3-4h, drying to constant weight in 110-120 DEG C of baking oven, obtains surface grafting polymerization
Polyester fiber cloth；
(2) chitosan-composite nano germicide-polyester fiber cloth preparation:
Hydrochloric acid solution is added into Chitosan powder, sufficiently dissolves, the lower dropwise addition sodium hydroxide solution of stirring to pH is 7-8, then plus
Enter composite nano germicide mixing, the polyester fiber cloth of gained surface grafting polymerization in (1) is sufficiently impregnated 4- wherein
5h takes out, is filtered dry surface moisture, air-dries in draught cupboard, obtains chitosan-composite nano germicide-polyester fiber cloth；
