Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, in particular to a blended yarn and a high-strength fabric thereof. Background Art

[0002] Currently, the upper materials of sports shoes on the market include natural leather, synthetic leather and mesh, among which mesh is woven from yarn. It has the characteristics of good elasticity and good breathability, is more comfortable to wear, and can have different structural designs to meet the needs of different sports. Therefore, mesh has gradually become one of the mainstream materials for sports shoes.

[0003] However, unlike the smooth and complete appearance of natural leather and synthetic leather, mesh fabric is easily damaged by abrasion or yarn snags due to its woven structure. Therefore, the strength of mesh fabric is easily affected by the properties of the yarn. If yarn with poor strength is used, the mesh fabric is easily damaged during exercise, thereby affecting the support and protection of the sneaker upper. Utility Model Content

[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of the blended yarn provided by the utility model. The blended yarn 1 includes a composite yarn 10 and a twisted yarn 20. The blended yarn 1 also includes some other functional modules, such as assembly components, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0020] The composite wire 10 includes a first wire 11 and a second wire 12. The first wire 11 and the second wire 12 are twisted and spirally wound with each other, and the first wire 11 and the second wire 12 are wound to form the composite wire 10.

[0021] The twisted yarn 20 and the composite yarn 10 are twisted together and spirally wound around each other, and the twisted yarn 20 and the composite yarn 10 are mixed together to form the blended yarn 1 .

[0022] The first thread 11, the second thread 12, and the twisted thread 20 all include a plurality of first fibers 111 and a plurality of second fibers 112. The first fibers 111 and the second fibers 112 in the first thread 11, the second thread 12, and the twisted thread 20 are twisted and spirally wound with each other. The first fiber 111 is a polyethylene terephthalate fiber, and the second fiber 112 is a polybutylene terephthalate fiber. Both the polyethylene terephthalate fiber and the polybutylene terephthalate fiber are recycled polyester fibers. Therefore, the composite thread 10 and the twisted thread 20 can be recycled and reused. The polyethylene terephthalate fiber and the polybutylene terephthalate fiber are both existing technologies.

[0023] Since polyethylene terephthalate fiber is light in weight and has good toughness, acid and alkali resistance and wear resistance, and polybutylene terephthalate fiber has good durability and air permeability, dimensional stability and elasticity, the twisted thread 20 has properties such as softness, lightness, air permeability, high elongation, high toughness and high bendability. In addition, polyethylene terephthalate fiber and polybutylene terephthalate fiber have different elastic coefficients and shrinkage rates, so that when the twisted thread 20 is stretched, its molecular chain is easy to deform but not easy to produce relative displacement, and the structure can remain stable, so after the external force is removed, the twisted thread 20 can return to its original state.

[0024] The quantity ratio of the first fiber 111 to the second fiber 112 in the first thread 11 , the second thread 12 , and the twisted thread 20 is 7:3 to 9:1.

[0025] The first fiber 111 and the second fiber 112 in the first silk thread 11, the second silk thread 12, and the twisted silk thread 20 all form a sheath 113 and a core 114, and the sheath 113 is wrapped around the outside of the core 114. The sheath 113 and the core 114 are formed by the first fiber 111 and the second fiber 112 being entangled with each other, that is, the first fiber 111 and the second fiber 112 can be arranged according to needs, and then twisted into the twisted silk thread 20, the first silk thread 11, and the second silk thread 12, and the sheath 113 and the core 114 are distinguished by different ratios of the first fiber 111 and the second fiber 112.

[0026] The ratio of the number of the first fiber 111 and the second fiber 112 in the sheath 113 may be 9:1, and the ratio of the number of the first fiber 111 and the second fiber 112 in the core 114 may be 7:3. By controlling the ratio of the first fiber 111 and the second fiber 112 in the sheath 113 and the core 114, the wear resistance and heat resistance of the twisted silk thread 20 can be further improved, and the shrinkage rate of the twisted silk thread 20 can be reduced.

[0027] The first thread 11 and the second thread 12 have the same or similar structure as the twisted thread 20, that is, the first thread 11 and the second thread 12 may have the same properties as the twisted thread 20, so they will not be described in detail here.

[0028] The twist of the composite yarn 10 can be 400 to 500 times / inch, the fineness of the composite yarn 10 can be 50d to 300d, and the twist of the blended yarn 1 can be 200 to 600 times / inch. In detail, the composite yarn 10 is first twisted until the twist and fineness of the composite yarn 10 reach the above range, and then the twisted composite yarn 10 and the twisted yarn 20 are twisted together into a blended yarn 1, and nylon fiber can also be twisted into the blended yarn 1 to increase the strength. As a result, the blended yarn 1 can have properties such as high elasticity, high wear resistance and high tear strength, and by adjusting the twist and fineness of the blended yarn 1, the properties of the blended yarn 1 can be further improved, so that the blended yarn 1 has better material properties.

[0029] like Figure 3 to Figure 4 As shown, it is a schematic diagram of the structure of the high-strength fabric provided by the utility model. The high-strength fabric includes a plurality of blended yarns 1 woven with each other. The woven structure between the plurality of blended yarns 1 is any one of a plain woven structure and a knitted structure. Figure 3 This is a schematic structural diagram of the first embodiment of the high-strength fabric provided by the utility model. The high-strength fabric is a plain woven structure. Figure 4This is a structural schematic diagram of the second embodiment of the high-strength fabric provided by the utility model. The high-strength fabric is a knitted structure. Both the plain woven structure and the knitted structure are existing technologies.

[0030] The plain weave structure is a plain weave, a twill weave or a satin weave. The plain weave structure can make the high-strength fabric firm, the texture more stable and straight, and can also improve the wear resistance of the high-strength fabric, thereby extending the service life of the high-strength fabric. The knitted structure is a weft knitted structure or a warp knitted structure. The knitted structure can improve the elasticity and softness of the high-strength fabric, while increasing the breathability of the high-strength fabric, thereby improving the comfort of the user when wearing the high-strength fabric. It must be particularly noted that since the blended yarn 1 has good strength and elasticity, the blended yarn 1 is suitable for a variety of different weaving methods and can bring good fabric properties.

[0031] Compared with the prior art, the blended yarn 1 provided by the utility model is twisted together by the composite thread 10 and the twisted thread 20. The composite thread 10 includes a first thread 11 and a second thread 12, the first thread 11 and the second thread 12 are twisted together and spirally wound with each other, the first thread 11, the second thread 12, and the twisted thread 20 all include a plurality of first fibers 111 and a plurality of second fibers 112, the first thread 11, the second thread 12, and the first fiber 111 and the second fiber 112 in the twisted thread 20 are twisted together and spirally wound with each other, and the performance is improved by the respective characteristics of the first fiber 111 and the second fiber 112, and the twisted thread 20 tightly winds the first thread 11 and the second thread 12 in the composite thread 10 together, thereby increasing the strength and stability of the composite thread 10. The high-strength fabric includes a plurality of interwoven blended yarns 1, and the strength of the fabric is improved by the blended yarns 1. It can be seen that the new blended yarn and its high-strength fabric are blended by blending the composite yarn 10 with the twisted yarn 20, so that the blended yarn has the characteristics of light weight and high strength.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
