Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a homewear fabric with far-infrared yarn. Background Technology

[0002] Fabric, as one of the three essential elements of clothing, not only defines the style and characteristics of garments but also directly affects wearing comfort. Existing publicly available technology proposes a six-loop woven far-infrared thermal fabric. This involves alternating weaving of thermal yarns and antibacterial composite yarns. Far-infrared yarns are woven in loops in loops 1, 3, and 5, while antibacterial yarns containing chitosan fibers are woven in loops 2, 4, and 6 using a combination of loop-float yarns. While this solution can alleviate the problem of bacteria growth from sweat, it has the following drawbacks: the single-planar weave structure causes humid and hot air to trap, easily leading to a stuffy feeling in environments of 25-30℃. Especially during seasonal transitions, traditional fabrics cannot simultaneously meet the contradictory needs of warmth in the morning and evening and breathability during the day. Therefore, it is necessary to optimize the structure of loungewear fabrics with far-infrared yarns to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a homewear fabric with far-infrared yarn.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a homewear fabric with far-infrared yarn, comprising a fabric body, the fabric body being composed of a surface layer, a middle layer, and an inner layer. The surface layer is a single-sided loop-woven layer, formed by weaving 32S / 1 combed cotton and far-infrared fibers. The far-infrared fibers comprise a matrix and multiple groups of radially distributed branches disposed on the circumferential outer wall of the matrix. A semi-circular protrusion is provided at the end of each branch away from the matrix, the protrusion height being 1-2 μm. Adjacent semi-circular protrusions... The center distance is 3-5μm. The middle layer is a loop-knitted layer formed by hollow polyester. The hollow polyester has a W-shaped cross-section, and moisture-wicking grooves with a depth of 3-5μm are formed between the four airfoils of the W-shaped cross-section. The hollow polyester airfoils have microporous cavities with a diameter of 50-300nm inside. The inner layer is a float-loop alternating woven layer with a honeycomb mesh structure and a mesh diameter of 0.5-1mm. The inner layer is made of 300D / 144F high-elastic polyester filament float-loop alternating woven layer.

[0005] As a further description of the above technical solution:

[0006] The inner layer is a honeycomb mesh structure in which the ratio of the length of the floating line to the height of the coil is 2:1 to 3:1.

[0007] As a further description of the above technical solution:

[0008] The hollow polyester has an angle of 85°-95° ​​between adjacent airfoils in its W-shaped cross-section, and the distribution density of micropore cavities inside the airfoils is 8-12 per μm.

[0009] As a further description of the above technical solution:

[0010] The inner honeycomb mesh structure has temperature-sensitive deformation fibers spirally wrapped around the mesh openings, with a wrapping density of 3-4 turns / mm.

[0011] As a further description of the above technical solution:

[0012] The fabric body, after being treated with single-sided fleece, has a loft of ≥11cm. 3 / g, moisture permeability ≥8500g / m 2 / 24h.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, this homewear fabric with far-infrared yarn features a honeycomb mesh edge wrapped with temperature-sensitive fibers. This design maintains the overall structural stability of the fabric while enabling the mesh to adapt to temperature changes, overcoming the fabric deformation problem caused by direct blending of traditional temperature-sensitive materials. The moisture-wicking grooves of the W-shaped cross-section hollow polyester and the microporous cavity form a capillary gradient, which, combined with the air convection channels of the honeycomb mesh, improves moisture permeability without reducing warmth retention.

[0015] 2. Compared with existing technologies, the three-dimensional structure formed by the semi-circular protrusions and branches of this homewear fabric with far-infrared yarn can effectively reduce the friction between fibers. After multiple standard washes, it can still maintain the radial distribution of the branches, thus reducing the attenuation rate of far-infrared emissivity. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 7 This utility model provides a type of loungewear fabric with far-infrared yarn: it includes a fabric body, which, after being treated with single-sided fleece, has a loft of ≥11cm. 3 / g, moisture permeability ≥8500g / m 2 / 24h, the fabric body consists of surface layer 1, middle layer 2 and inner layer 3;

[0027] By setting up a top layer 1, a middle layer 2, and an inner layer 3, the synergistic effect of the three-layer composite structure is achieved, which solves the technical problem of temperature and humidity imbalance in traditional fabrics while ensuring basic wearability.

[0028] To enhance the durability of the far-infrared function and wearing comfort, the surface layer 1 is a single-sided loop woven layer, which is woven from 32S / 1 combed cotton 101 and far-infrared fiber 102. The far-infrared fiber 102 includes a matrix 1021 and multiple sets of radially distributed branches 1022 disposed on the outer wall of the matrix 1021. A semi-circular protrusion 1023 is provided at the end of the branch 1022 away from the matrix 1021. The height of the protrusion is 1-2μm, and the center distance between adjacent semi-circular protrusions 1023 is 3-5μm.

[0029] The three-dimensional structure formed by the semi-circular protrusion 1023 and the branch 1022 can effectively reduce the friction between fibers. After 20 standard washes, the radial distribution of the branch 1022 can still be maintained, so that the far-infrared emissivity attenuation rate is controlled within 8%.

[0030] To establish a gradient moisture-wicking channel, the intermediate layer 2 is a loop-woven layer formed by hollow polyester 201. The cross-section of the hollow polyester 201 is W-shaped, and moisture-wicking grooves 202 with a depth of 3-5μm are formed between the four airfoils of the W-shaped cross-section. The airfoils of the hollow polyester 201 have microporous cavities with a diameter of 50-300nm inside. The included angle between adjacent airfoils in the W-shaped cross-section of the hollow polyester 201 is 85°-95°, and the distribution density of microporous cavities inside the airfoils is 8-12 per μm.

[0031] The W-shaped cross-section of the wing body and the moisture-wicking groove 202 form a capillary effect gradient. When the humidity of the inner layer of the fabric is >65%RH, it can guide liquid water to diffuse rapidly to the outer layer through the groove 202. The measured moisture permeability at 25℃ is increased to 8800±300g / m². 2 / 24h;

[0032] To achieve dynamic temperature response, inner layer 3 is a floating-loop alternating woven layer with a honeycomb mesh structure and a mesh diameter of 0.5-1mm. Inner layer 3 is made of 300D / 144F high-elastic polyester filament 301 floating-loop alternating woven layer. In the honeycomb mesh structure of inner layer 3, the ratio of floating length to loop height is 2:1 to 3:1. The periphery of the honeycomb mesh structure of inner layer 3 is spirally wrapped with temperature-sensitive deformation fiber 302 with a wrapping density of 3-4 turns / mm.

[0033] When the ambient temperature is greater than 25°C, the temperature-sensitive deformable fiber 302 shrinks, causing the mesh to expand and increasing the pore size by 15%-20%. This, together with the moisture-guiding grooves 202 of the intermediate layer 2, forms an air convection channel, effectively solving the problem of humid and hot air retention mentioned in the background art.

[0034] Working principle: By setting up a surface layer 1, a middle layer 2, and an inner layer 3, the synergistic effect of the three-layer composite structure is achieved. While ensuring basic performance, it solves the technical problem of temperature and humidity imbalance in traditional fabrics. The three-dimensional structure formed by the semi-circular protrusions 1023 and branches 1022 effectively reduces inter-fiber friction. After 20 standard washes, the radial distribution of branches 1022 is maintained, keeping the far-infrared emissivity attenuation rate below 8%. The W-shaped cross-section of the wings and the moisture-wicking grooves 202 form a capillary effect gradient. When the humidity of the inner layer of the fabric is >65%RH, liquid water can be guided to diffuse rapidly to the outer layer through the grooves 202. The measured moisture permeability at 25℃ is increased to 8800±300g / m². 2 / 24h; When the ambient temperature is >25℃, the temperature-sensitive deformable fiber 302 shrinks and drives the mesh to expand, increasing the pore size by 15%-20%, which, together with the moisture-guiding groove 202 of the intermediate layer 2, forms an air convection channel, effectively solving the problem of humid and hot air retention mentioned in the background technology.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
