Abstract

A semi-worsted yarn with antibacterial and anti-wrinkle properties and a processing method thereof, involving the use of 2-Br isobutyryl bromide initiator, diethylaminoethyl methacrylate as a monomer to prepare a water-soluble modifying agent, and The technical field of modifying semi-worsted yarns by using water-soluble modifiers in steaming treatment process. The invention uses the principle of active polymerization-atom transfer radical polymerization to realize the grafting of the modified monomer on the semi-worsted yarn through the covalent bond of bromine, thereby realizing the functions of antibacterial and anti-wrinkle. The invention solves the disadvantages of conventional antibacterial and moisture-absorbing modification such as poor durability, complicated processing flow, poor water solubility of modifiers, difficulty in synchronously performing yarn processing, and the like. The semi-worsted yarn prepared by the invention has antibacterial and anti-wrinkle functions, and can be widely used in fields such as clothing and industrial fabrics.

Description

A kind of have antibiotic and spining semi-worsted yarn line and processing method thereof wrinkle resistance

Technical field

The present invention relates to a kind of processing method of functional spining semi-worsted yarn line, be specifically related to utilize 2-Br isobutyl acylbromide to be initator, esters of acrylic acid is that monomer prepares water-soluble modified dose, and in half spinning manufacturing procedure, use Transfer Radical Polymerization in water-soluble modified dose, the spining semi-worsted yarn line to be carried out technical fields such as modification.

Technical background

Half spinning and traditional in the past maximum difference spinning, slubbing technology is, it combines cotton spinning technology and wool spinning technology together, form a kind of novel multicomponent hybrid technique, thereby solved flow process and problems such as quality control is difficult to unify in the processing of original wool spinning and cotton spinning apparatus.The novel semi-spinning yarn can be used to produce spinning, slubbing lining and knitting woollen product, and the physical property of its ready-made clothes and outward appearance, texture, comfort level obtain very big improvement and abundant.But it is less relatively at present the spining semi-worsted yarn line to be carried out the research of functionalization, improves the modification of aspect such as antibiotic and crease-resistant especially simultaneously, the patent documentation that Shang Weiyou publishes or publishes.

Fiber, yarn or textile material mainly contain two kinds of antibiotic modes at present, i.e. dissolution type and non-dissolution type.The dissolution type antiseptic forms antibacterial ring around yarn, thereby kills the Related Bacteria in the antibacterial ring or suppress its growth; But not the dissolution type sample then is to add antiseptic in sample interior such as yarns; in case relevant mushroom touches yarn; then because the effect of the antiseptic of yarn own; growth will is killed or suppress to this bacterioid; domestic and international most of document and patent all concentrate on the formal of antibiotic processing at present, and publication and document do not appear both at home and abroad in the present invention's related right required for protection as yet.

In the antibiotic machining technology of yarn, mainly contain following several processing method: (1) chemic modified method, this method mainly is the yam surface that chemical group is grafted to required modification, implant antiseptic such as patent CN101643953 (2) at fiber or yam surface, promptly in spinning process, the finishing agent that will have antibacterial functions is sneaked in the spinning solution, thereby changes fiber and yarn anti-microbial property, and this type of yarn has long-acting bacteriostasis property.Such as patent CN 01820026.5, introduced a kind of antiseized spandex yarn that contains antiseptic and, mainly be to use the method for some Physical Processing to adhere to functional group with antibiotic or bacteriostasis property at fiber surface or shallow top layer with fabric (3) the physical modification method of its manufacturing.Such as, the patent No. 01115422.5 has been introduced the method that adopts physics and has been shown that at yarn adhering to Nano Silver realizes antibiotic; The number of applying for a patent 200610161811.5, introduced nano zine oxide that antibacterial effect is arranged or silver directly gluing on bamboo fibre, again bamboo fibre is directly carried out the high temperature carbonization program, with surperficial tool cohere the anti-bacterial bamboo charcoal fiber of antimicrobial particle, thereby realize antibacterial effect.But above-mentioned modification method for sorting all exists anti-bacterial wet-absorbing function persistence poor, shortcomings such as modified technique flow process complexity.

Because it is initator that the present invention has adopted 2-Br isobutyl acylbromide, and uses triethylamine to be acid binding agent, diethylaminoethyl methacrylate is a monomer, and the modifier of preparation has characteristics such as water-soluble, has overcome the shortcoming of modified technique complexity.The present invention adopts the method for atom transfer radical polymerization simultaneously, and acrylic ester monomer is grafted on the spining semi-worsted yarn line, when giving its antibiotic and moisture absorbing, has also solved the shortcoming that the modified yarn function does not wait lastingly.

Summary of the invention

The purpose of this invention is to provide the antibiotic technology with the wrinkle resistance modification of a kind of easy spining semi-worsted yarn line, proposed a kind of water-soluble modified dose preparation method simultaneously.

For achieving the above object, the technical solution used in the present invention prepares water-soluble modified dose for using catalyst and acid binding agent acting in conjunction, takes Transfer Radical Polymerization modification spining semi-worsted yarn line, and concrete steps are as follows:

(1) preparation of macromole evocating agent adds a certain amount of catalyst 4-diamino-pyridine in reactor, with the oxolane dissolving, add triethylamine again and shake up, and slowly drips 2-Br isobutyl acylbromide.

(2) 2-Br isobutyl acylbromide initator is used in the preparation of modifier, and to take triethylamine be acid binding agent, and diethylaminoethyl methacrylate is a monomer, places under the constant temperature to react in reactor, makes water-soluble modified dose.

(3) graft modification of spining semi-worsted yarn line places water-soluble modified dose to add hot water storgae in the yarn steaming operation, and the heating uniform temperature makes ethyl acrylate be grafted in the spining semi-worsted yarn line under the effect of catalyst etc.

(4) dry spining semi-worsted yarn line.

Owing to adopted technique scheme, the present invention to have following advantage and effect:

(1) the present invention has taked the method for atom transfer radical polymerization to realize esters of acrylic acid adhering on the spining semi-worsted yarn line having improved the attachment fastness of group in yam surface, makes antibiotic and moisture pick-up properties significantly promotes.

(2) modifier of the present invention is the aqueous solution, and pH value has certain environmental protection effect near neutral.
