Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile fabrics, in particular to a cool and cooling knitted fabric. Background Art
[0002] Knitted cotton fabric is a widely used textile material, favored by consumers for its excellent skin-friendliness and moisture-absorbing properties. However, knitted cotton fabric has two major drawbacks. First, it has poor quick-drying properties. Under high temperatures or heat exposure, human sweat is absorbed by the fabric, making it sticky to the skin. Second, it has poor heat dissipation performance. It has a strong barrier to infrared radiation emitted by the human body; ordinary cotton knitted fabric has a human infrared transmission rate of less than 1%. Furthermore, cotton yarn has poor thermal conductivity, which prevents it from transferring human body temperature to the surface of the body, seriously affecting its heat dissipation capacity.
[0003] In order to solve the above technical problems, the existing technical solutions mainly improve the heat dissipation and quick-drying performance of the fabric through the following aspects:
[0004] (1) The mercerized cotton process is used to improve the cool feeling of the fabric. The liquid ammonia treatment process causes the cotton fibers to swell, which improves the cool feeling of the fabric. Although this treatment increases the smoothness and cool feeling of the fabric, it also reduces its sweat absorption and quick-drying properties.
[0005] (2) Some additives are used to improve the heat dissipation performance of the fabric. However, for cotton materials, the additives have very poor wash resistance and generally become completely ineffective after washing 5 times, which limits the widespread and durable use of this method in practical applications.
[0006] The above defects need to be solved urgently. Utility Model Content
[0007] In order to solve the problems of poor quick-drying performance and poor heat dissipation of existing knitted cotton fabrics, the utility model provides a cool and cooling knitted fabric.
[0008] The technical solution of this utility model is as follows:
[0009] A cooling knitted fabric comprises a cotton yarn group and a cooling yarn group, wherein the cotton yarn group and the cooling yarn group are alternately arranged, and each of the cotton yarn group and the cooling yarn group forms a plurality of coils along the transverse direction of the fabric, and each of the coils is sequentially interlaced with each other in the longitudinal direction of the fabric, and the cooling yarn monomers of the cooling yarn group are yarns with high infrared transmittance to the human body, such as nylon yarn or polyethylene yarn filled with zinc oxide.
[0010] According to the above-mentioned solution of the utility model, the cotton yarn group includes two cotton yarn monomers, and the two cotton yarn monomers are arranged in sequence along the longitudinal direction of the fabric;
[0011] The cooling yarn group includes two cooling yarn monomers, and the two cooling yarn monomers are arranged in sequence along the longitudinal direction of the fabric.
[0012] According to the above-mentioned solution of the present invention, the yarn count of the cotton yarn monomer is 50S.
[0013] According to the above-mentioned solution of the present invention, the material of the cotton yarn monomer is long-staple cotton.
[0014] According to the above solution of the present invention, the fineness of the nylon yarn is 70 denier.
[0015] According to the above-mentioned solution of the present invention, the nylon yarn is composed of 48 monofilaments.
[0016] According to the above solution of the present invention, the fineness of the polyethylene yarn is 70 denier.
[0017] According to the above-mentioned solution of the utility model, the polyethylene yarn is composed of 36 monofilaments.
[0018] According to the above-mentioned solution of the present invention, the cooling yarn monomer is a fully drawn yarn.
[0019] According to the utility model of the above solution, the median particle size of the zinc oxide is 500-1000 nm.
[0020] The utility model according to the above solution has the following beneficial effects:
[0021] In the aforementioned cooling knitted fabric, cotton yarn groups and cooling yarn groups are alternately arranged. Both the cotton and cooling yarn groups form multiple coils along the fabric's transverse direction, with the coils interlaced in sequence along the fabric's longitudinal direction. Because the cooling yarn group has a better quick-drying performance than the cotton yarn group, the fabric not only maintains the skin-friendliness of cotton but also improves its quick-drying properties and reduces skin stickiness. Furthermore, the alternating arrangement of the cotton and cooling yarn groups creates pores in the fabric that are not made of cotton material, resulting in excellent infrared transmittance to the human body and improved heat dissipation.
[0022] In addition, the cool yarn monomer of the cool yarn group is a yarn with high human infrared penetration, such as nylon yarn or polyethylene yarn filled with zinc oxide. Since nylon yarn or polyethylene yarn has excellent human infrared penetration performance, and zinc oxide absorbs less human infrared, it can improve the human infrared penetration performance of the yarn, ensuring that the heat generated by the human body can be dissipated through the yarn. At the same time, zinc oxide also has high thermal conductivity, which enhances the cooling effect of the yarn; in addition, zinc oxide also has a strong absorption or reflection effect on ultraviolet rays, which improves the sun protection performance of the fabric, and the zinc oxide particles with a median particle size of 500nm to 1000nm also have a high reflection function for sunlight, which effectively reduces the temperature rise of the human body caused by sunlight, thereby playing a cooling role.

[0027] It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may also be an intermediate element; when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0029] In the existing technical solutions, the heat dissipation and quick-drying properties of fabrics are mainly improved through the following aspects: (1) using mercerized cotton processing technology and integrating liquid ammonia treatment steps to promote the swelling effect of cotton fibers, thereby enhancing the cool feeling of the fabric when it comes into contact with the skin. Although this method improves the smoothness and cooling effect of the fabric, it also weakens the moisture absorption and perspiration performance and quick-drying characteristics of the fabric; (2) by adding specific additives to enhance the heat dissipation performance of the fabric. However, for cotton materials, these additives have poor washing resistance and usually lose their effect completely after 5 washes, which limits the popularity and long-term effectiveness of this solution in practical applications.
[0030] Example 1
[0031] like Figure 1 As shown, in order to solve the above technical problems, the utility model provides a cooling knitted fabric, comprising a cotton yarn group and a cooling yarn group, wherein the cotton yarn group and the cooling yarn group are alternately arranged, and each of the cotton yarn group and the cooling yarn group forms a plurality of coils along the transverse direction of the fabric, and each coil is sequentially interlaced with each other in the longitudinal direction of the fabric. Since the cooling yarn group has a better quick-drying performance than the cotton yarn group, the fabric not only maintains the skin-friendliness of cotton, but also improves the quick-drying performance of the fabric and reduces the stickiness of the fabric. At the same time, since the cotton yarn group and the cooling yarn group are alternately arranged, pores of non-cotton materials appear in the fabric, thereby making the fabric have good infrared transmittance to the human body, thereby improving the heat dissipation performance of the fabric.
[0032] like Figure 1 、 Figure 2 As shown, in this embodiment, the cotton yarn group includes two cotton yarn monomers 11, and the two cotton yarn monomers 11 are arranged in sequence along the longitudinal direction of the fabric, and each cotton yarn monomer is sequentially formed with a number of first coils 12 along the transverse direction of the fabric, and each first coil 12 is sequentially strung together in the longitudinal direction of the fabric; at the same time, the cooling yarn group includes two cooling yarn monomers 21, and the two cooling yarn monomers 21 are sequentially arranged along the longitudinal direction of the fabric, and each cooling yarn monomer 21 is sequentially formed with a number of second coils 22 along the transverse direction of the fabric, and each second coil 22 is sequentially strung together in the longitudinal direction of the fabric, and the first coils 12 of the upper and lower adjacent cotton yarn monomers 11 and the second coils 22 of the cooling yarn monomers 21 are sequentially strung together in the longitudinal direction of the fabric.
[0033] like Figure 2As shown, in this embodiment, counting from top to bottom, the first horizontal coil and the second horizontal coil are cotton yarn monomers 11, and the third horizontal coil and the fourth horizontal coil are cool yarn monomers 21. When the fabric is weaving, the cotton yarn monomers 11 and the cool yarn monomers 21 are fed in sequence of "2+2" for weaving, that is, the first yarn is the cotton yarn monomer 11, which is used to weave the first horizontal coil; the second yarn is the cotton yarn monomer 11, which is used to weave the second horizontal coil; the third yarn is the cool yarn monomer 21, which is used to weave The fourth yarn is a cooling yarn monomer 21, which is used to weave the fourth row of coils. The four yarns are woven repeatedly until the fabric is woven. This ensures that pores of non-cotton materials appear in the fabric, providing space for the fabric to transmit infrared light, allowing the fabric to release heat generated by the human body, thereby further improving the fabric's heat dissipation performance. At the same time, in terms of skin feel, it can maintain the skin-friendly feel of cotton and effectively transfer human heat to the fabric surface for heat dissipation, thereby enhancing the fabric's heat dissipation capacity. In addition, after the fabric is woven, it is dyed and finished using a semi-bleaching process, and finally shaped.
[0034] In this embodiment, the cool yarn monomer 21 of the cool yarn group is a yarn with high human infrared penetration, such as nylon yarn filled with zinc oxide. Since nylon yarn or polyethylene yarn has excellent human infrared penetration performance, and zinc oxide has less absorption of human infrared, it can improve the human infrared penetration performance of the yarn, ensuring that the heat generated by the human body can be dissipated through the yarn. At the same time, zinc oxide also has high thermal conductivity, which enhances the cooling effect of the yarn; in addition, zinc oxide also has a strong absorption or reflection effect on ultraviolet rays, which improves the sun protection performance of the fabric. Of course, the cool yarn monomer 21 can also be designed to be other yarns with high human infrared penetration. In actual design, the material of the cool yarn monomer 21 can be designed according to actual needs.
[0035] During the production of zinc oxide-filled nylon yarn, zinc oxide particles are incorporated into the nylon through a melt spinning process. The nylon is melted and then extruded through a spinneret to form fibers, with the zinc oxide particles evenly dispersed throughout the fibers. It should be noted that the melt spinning process is prior art, and this utility model also improves upon this process, so its principles and process will not be described in detail.
[0036] In this embodiment, the median particle size of zinc oxide is 500-1000nm. Zinc oxide particles with a median particle size of 500nm-1000nm have a high reflectivity to sunlight, effectively reducing the temperature rise of the human body caused by sunlight exposure, thereby playing a cooling role. In addition, the median particle size of zinc oxide can be designed to be 500nm. That is, in the particle size distribution of zinc oxide nanoparticles, half of the particles have a diameter less than 500nm, and the other half have a diameter greater than 500nm. At the same time, zinc oxide with a median diameter of 500nm also has a high reflectivity to sunlight. When sunlight shines on the yarn surface, the zinc oxide particles can reflect some of the light back, thereby reducing direct sunlight exposure to the skin, improving the sun protection ability of the yarn, and providing additional protection for the wearer. Of course, in actual design, the median particle size of zinc oxide can be designed according to actual needs.
[0037] In this embodiment, the cotton yarn 11 is made of long-staple cotton and has a yarn count of 50S, meaning the yarn is relatively fine. High-count cotton yarns can form more and finer fiber interlacing points during weaving, which not only enhances the structural stability of the fabric but also improves its breathability, providing superior moisture wicking properties and making it more comfortable and breathable to wear. Of course, in actual design, the yarn count of the cotton yarn 11 can be adjusted based on actual needs.
[0038] In this embodiment, the nylon yarn has a fineness of 70 denier and is filled with 3% zinc oxide, with a median particle size of 500 nm. Nylon has better quick-drying properties than cotton, which can improve the quick-drying properties of the fabric and reduce the fabric's stickiness. In addition, nylon has good thermal conductivity, which also plays a certain role in the conduction of human body heat, enhancing the fabric's heat dissipation function. Furthermore, the cooling yarn monomer 21 is composed of 48 monofilaments, and the cooling yarn monomer 21 is a fully drawn yarn (FDY). By fully stretching the fiber, the molecular arrangement and elasticity of the fiber are further improved, thereby ensuring the stability of the yarn and fabric.
[0039] It should be noted that yarn count (S) indicates the thickness of short fibers, and denier (D) indicates the thickness of long fibers.
[0040] Example 2
[0041] Unlike the first embodiment, in this embodiment, the cooling yarn monomer 21 of the cooling yarn group is a ethylene yarn filled with zinc oxide. The fineness of the ethylene yarn is 70 denier, and the ethylene is filled with 3% zinc oxide. The median particle size of the zinc oxide is 500nm. The quick-drying performance of ethylene is better than cotton, which can improve the quick-drying property of the fabric and reduce the stickiness of the fabric. In addition, nylon has good thermal conductivity and also plays a certain role in the conduction of human body heat, thereby enhancing the heat dissipation function of the fabric. In addition, the cooling yarn monomer 21 is composed of 36 monofilaments, and the cooling yarn monomer 21 is a fully drawn yarn (FDY). By fully stretching the fiber, the molecular arrangement and elasticity of the fiber are further improved, thereby ensuring the stability of the yarn and fabric.
[0042] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
[0043] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
