The utility model discloses further set up to: the winding silk is 5D nylon filament.
The utility model discloses further set up to: the protective layer is 40D nylon filament, and the 40D nylon filament is wound on the outer side of the middle layer.
The beneficial effects of the utility model are that:
1. the central fiber is made of 40D spandex elastic yarns with circular sections, and the 40D spandex yarns have good elasticity and elastic resilience, so that the possibility of deformation of the yarns in the stretching process is reduced.
2. The elastic monofilaments in the fiber group are twisted and crossed in the length direction to form a twisted shape, when the elastic monofilaments are subjected to external force, the friction force between the elastic monofilaments and the elastic monofilaments is increased, the relative movement is reduced, and finally the strength of the fiber group is greatly enhanced.
3. The winding silk adopts 5D nylon filament, and the characteristics of nylon filament are that the wearability is higher than other fibre, therefore, the winding of winding silk can increase the anti-dissapability of fibre group, and its characteristics can increase the wearability of fibre group to a certain extent again.
4. The protective layer adopts 40D nylon filament, and the yarn count is thicker than the 5D nylon filament of twining on adding on the bullet monofilament, and 40D nylon filament's wearability and intensity are more excellent, as outermost winding yarn, can very big increase dacron add the wearability of bullet silk body.
Drawings
FIG. 1 is a cross-sectional view of the yarn of the present invention;
fig. 2 is a perspective view of the elastic monofilament winding of the present invention.
In the figure: the elastic fiber comprises a protective layer 2, a fiber group 3, a winding wire 4, an elastic monofilament 5, an intermediate layer 6 and a central fiber 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a wear-resistant polyester plus stretch yarn comprises a polyester plus stretch yarn body, wherein the polyester plus stretch yarn body is formed by compounding a plurality of layers, and the polyester plus stretch yarn body is respectively provided with a protective layer 2, an intermediate layer 6 and a central fiber 7 from outside to inside. The central point that dacron adds the stretch yarn body is located to central fibre 7 puts, and central fibre 7 chooses for use the cross-section to be the circular shape 40D spandex stretch yarn, and 40D spandex yarn has good elasticity and elasticity resilience nature to the yarn count thickness of 40D spandex yarn is moderate, can reduce the possibility that the yarn takes place deformation when tensile on the basis that does not influence dacron and add the stretch yarn body and feel.
The periphery of the central fiber 7 is the middle layer 6, a plurality of fiber groups 3 are arranged in the middle layer 6, the fiber groups 3 are uniformly distributed on the outer side of the central fiber 7, the central fiber 7 is wrapped in the middle, the central fiber 7 is wrapped on the innermost side by the fiber groups 3, and the phenomenon of spandex exposure can be prevented.
The fiber group 3 comprises a winding filament 4 and a plurality of elastic monofilaments 5, wherein three elastic monofilaments 5 are arranged in each fiber group 3, and the elastic monofilaments 5 in each fiber group 3 are arranged in a delta shape on the cross section, so that the whole cross section of the fiber group 3 is triangular. The elastic monofilaments 5 in each fiber group 3 are twisted and cross-wound in the length direction to form a twisted shape, and when an external force is applied, the frictional force between the elastic monofilaments 5 which are mutually wound is larger than that of the elastic monofilaments 5 in a parallel arrangement state, so that the relative movement between the elastic monofilaments 5 can be reduced, and the strength of the fiber group 3 is greatly enhanced.
The winding wire 4 is wrapped on the outer side of the elastic monofilament 5, and in the winding process, tight winding is not performed, a certain distance is reserved for winding, so that the elasticity of the elastic monofilament 5 in the fiber group 3 can be ensured not to be influenced in the using process. The 5D nylon filament is adopted by the winding silk 4, and the nylon filament has the greatest characteristic that the wear resistance is higher than that of all other fibers, so that the anti-falling performance of the fiber group 3 can be improved by winding the winding silk 4, and the wear resistance of the fiber group 3 can be improved to a certain extent by the characteristics of the winding silk 4. The yarn count of the 5D nylon filament yarn is fine, so that the overall hand feeling of the fiber group 3 is fine and smooth, and after the terylene textured yarn body is formed, the yarn integrally presents soft and elastic hand feeling.
The most advanced of the article font of fibre group 3 is towards central fibre 7, and the straight one side of 3 article fonts of fibre group is towards inoxidizing coating 2, can make fibre group 3 towards inoxidizing coating 2 one side can form nearly circular from this, and the inoxidizing coating 2 of being convenient for twines, and makes inoxidizing coating 2 keep circular state.
The periphery in intermediate level 6 is located to inoxidizing coating 2, and inoxidizing coating 2 adopts 40D nylon filament, and is thicker than winding 5D nylon filament on the monofilament that elasticizes 5, and 40D nylon filament's wearability and intensity are more excellent, and as outermost winding yarn, increase dacron that can be very big adds the wearability of the silk body that elasticizes, simultaneously, because 40D nylon filament closely twines in the 6 outsides in intermediate level, has good anti-colluding silk effect.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
