Description

Technical Field

[0001] The utility model relates to a Tencel cotton vortex spun yarn, belonging to the technical field of textile yarns. Background Art

[0002] Tencel fiber is a cellulose fiber with excellent properties such as soft hand feel, beautiful luster, good drape and good moisture absorption and breathability. Tencel and cotton are both cellulose fibers. By blending the two materials, the excellent properties of the two can be integrated to create a texture that is completely different from pure cotton fabrics, optimize the feel and moisture management function of the fabric, and make the fabric more shiny, smooth and comfortable. Winter clothing requires warm yarns. Yarns with more pores inside have static air in the internal gaps and have good thermal insulation effects. However, due to the squeezing of the adjacent yarns, the cross-section of the yarn in the fabric is flat, which reduces the internal gaps and reduces its thermal insulation effect.

[0003] How to develop a Tencel cotton vortex spun yarn that has the characteristics of Tencel cotton fiber on the surface and has more pores inside and has good thermal insulation effect has become a problem to be solved. Utility Model Content

[0004] The utility model aims to provide a Tencel cotton vortex spun yarn, which has more gaps inside and has good warmth-keeping effect.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0006] The utility model relates to a Tencel cotton vortex spun yarn, comprising a core yarn, a first covering fiber layer, a first wrapping yarn layer and a second wrapping yarn layer;

[0007] The core yarn comprises wool-PVA blended yarn, the first covering fiber layer is hollow polyester fiber, the first wrapping yarn layer comprises parallel-twisted flax fiber yarn and hot-melt filament; and the second wrapping yarn layer comprises Tencel-cotton blended yarn.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: a second covering fiber layer is arranged between the first covering fiber layer and the first wrapped yarn layer, and the second covering fiber layer is antibacterial polyester fiber.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the second wrapping yarn layer also includes conductive yarn.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the conductive yarn includes nylon fiber and a carbon nanotube conductive layer coated on the outside of the nylon fiber.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the hot-melt filament is nylon hot-melt filament, polyester hot-melt filament or TPU hot-melt filament.

[0012] The beneficial effects of the utility model are as follows: the Tencel cotton vortex spun yarn involved in the utility model adopts PVA fiber in the core yarn, so that the woven fabric can be dissolved in water after hot water treatment, thereby leaving a large number of gaps, and has a good warming effect. In addition, the flax fiber yarn used has good rigidity, and the hot-melt filament can bond the flax fiber with adjacent fibers, thereby reducing the deformation of the cross-section of the vortex spun yarn.

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 The present embodiment is described in detail. The present embodiment involves a Tencel cotton vortex spun yarn, comprising a core yarn 1, a first covering fiber layer 2, a first wrapping yarn layer 3 and a second wrapping yarn layer 4.

[0019] The core yarn 1 includes wool PVA blended yarn. The wool PVA blended yarn used is prepared by PVA co-spinning technology, wherein the PVA fiber used is low-temperature PVA water-soluble fiber, which is blended with wool fiber in a certain proportion, and the PVA fiber is removed during the finishing process of the woven fabric, so that the core yarn 1 retains more gaps, thereby improving the warmth retention effect and reducing the surface density of the fabric.

[0020] The first coating fiber layer 2 is hollow polyester fiber, which has a good thermal insulation effect. When combined with the core yarn 1 after the PVA fiber is removed, the thermal insulation of the vortex spun yarn can be effectively improved.

[0021] The first wrapping yarn layer 3 includes flax fiber yarn and hot-melt filaments twisted together. Flax fiber has high rigidity. Hot-melt filaments can melt when the yarn or fabric is heat-treated, and can bond the flax fiber yarn to adjacent fibers. The combination of flax fiber yarn and hot-melt filaments can reduce the extrusion of the yarn on the vortex spun yarn, and can retain more gaps.

[0022] The second wrapping yarn layer 4 comprises a Tencel-cotton blended yarn. The blended yarn of Tencel fiber and cotton fiber can embody the characteristics of cotton fiber and Tencel fiber.

[0023] Further, the hot-melt filament is nylon hot-melt yarn, polyester hot-melt yarn or TPU hot-melt yarn. In this embodiment, the hot-melt yarn is polyester hot-melt yarn with a fineness of 100-300D, and 150D is selected in this embodiment.

[0024] The Tencel cotton vortex spun yarn involved in this embodiment adopts the production process of vortex core-spun yarn to wrap the first covering fiber layer 2 on the outside of the core yarn 1, and sequentially wrap the first wrapping yarn layer 3 and the second wrapping yarn layer 4 on the outside of the first covering fiber layer 2.

[0025] Embodiment 2

[0026] Combination Figure 2 , this embodiment is described in detail. The Tencel cotton vortex spinning yarn involved in this embodiment is different from that of the first embodiment in that a second coating fiber layer 5 is provided between the first coating fiber layer 2 and the first wrapping yarn layer 3, and the second coating fiber layer 5 is antibacterial polyester fiber. Antibacterial polyester fiber can provide antibacterial properties.

[0027] Another difference from the first embodiment is that the second wrapped yarn layer 4 also includes conductive yarn. The conductive yarn includes nylon fiber and a carbon nanotube conductive layer coated on the outside of the nylon fiber. Carbon nanotubes (CNTs) are a typical nanomaterial with excellent mechanical properties, conductive properties and chemical properties. And the conductive yarn and the Tencel cotton blended yarn are parallel devices.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
