Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1-2, the differential shrinkage antibacterial polyester low stretch yarn comprises a metal wire 3 and cotton threads 1 sleeved outside the metal wire 3, and two adjacent groups of cotton threads 1 are connected by arranging polyester threads 2, wherein,
an antibacterial wire 4 for antibacterial purpose is bonded to the outside of the metal wire 3.
Referring to fig. 2, the antibacterial threads 4 are filled with an antibacterial agent including chitin, castor oil, and silver silica gel.
Referring to fig. 1 and 2, the polyester yarn 2 is provided with a plurality of groups.
Referring to fig. 3, the processing technology of the differential shrinkage antibacterial polyester drawn textured yarn is characterized by comprising the following steps:
and (3) antibacterial treatment: bonding cotton wires to the outside of the metal wire 3, soaking the cotton wires in a solution after the antibacterial agent is melted, coating glue on the outside of the metal wire 3 when the cotton wires are bonded, bonding the cotton wires to the outside of the metal wire 3, soaking the cotton wires in the melted antibacterial agent solution for 32min to obtain an antibacterial layer, and similarly, adhering 3 antibacterial layers to the outside of the metal wire 3;
manufacturing basic wires: winding a plurality of groups of polyester yarns 2 outside the metal yarns 3 after the antibacterial treatment to obtain basic yarns;
preparing cotton fiber: the method comprises the following steps of bonding a cotton fiber pad to the outside of basic silk, cutting off the redundant cotton fiber pad to obtain polyester filament yarn, wherein when the cotton fiber is manufactured, the cotton fiber pad is paved into sheets by the cotton fiber yarn, and then the cotton fiber pad is cut into saw-toothed shapes, wherein the saw teeth are rectangular;
manufacturing low stretch yarn: the polyester filament yarn is sequentially subjected to heating and destressing by a network nozzle, a yarn guide, a first pair of traction rollers and an induction heating roller, a second pair of traction rollers are used for drafting, a hot box is used for heating and destressing, the polyester filament yarn is introduced into a false twisting machine for false twisting after being cooled, then the polyester filament yarn is wound to obtain the polyester low-stretch yarn, when the low-stretch yarn is manufactured, the stretching ratio of the first pair of traction rollers is 1.1, the stretching ratio of the second pair of traction rollers is 1.5, the temperature of the induction heating roller is 155 ℃, and the heating temperature of the hot box is 120.
During the use, when user's body temperature was too high, 3 expansions of metal silk in low stretch yarn center department, because metal silk 3 is different rather than the 1 expansion coefficient of cotton silk thread of outside, consequently when being heated, metal silk 3 expands on a large scale, and 1 miniverum inflation of cotton silk thread, cotton silk 1 was elongated this moment, the dacron silk 2 of connecting between cotton silk 1 is stretched, closely laminate with 4 outsides of antibiotic silk, the grow of clothes simultaneously, thereby avoid extrudeing user's health, make the clearance increase between the silk thread, therefore improve the gas permeability of clothes, when user's body temperature descends, 3 large-scale shrink ann of metal silk, and 1 miniverum shrinkage of cotton silk thread, the dacron silk 2 of connecting between cotton silk 1 this moment is extruded, make dacron silk 2 extrude each other, fold the clearance between the silk thread, thereby reduce the heat effluvium of user's health.
When the static electricity is generated on the body of the user, the static electricity can be conducted outwards through the metal wire 3 in the low-elasticity wire, so that the static electricity on the body of the user can be reduced.
When bacterium or virus adhesion to the inside antibiotic silk 4 of low stretch yarn, be located antibiotic silk 4 inside antiseptic and kill bacterium or virus, thereby prevent bacterium or virus at low stretch yarn surface gathering, simultaneously because antibiotic silk 4 comprises the antibiotic layer of multilayer, and link to each other through glue bonding between two sets of antibiotic layers, can reduce the loss of antiseptic, thereby carry out long-term antibiotic, when using once more, can soak the low stretch yarn in the antiseptic, when antiseptic and antibiotic layer contact, can pin layer upon layer, improve low stretch yarn bactericidal effect, convenient used repeatedly.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
