Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a cool sun-proof knitted fabric. Background Art

[0002] Knitted cotton fabric, a textile material widely used in apparel, home furnishings, and various industrial sectors, has long been a favorite and trusted choice among consumers for its exceptional skin-friendliness and superior moisture absorption properties. Knitted cotton fabric, with its soft and delicate touch and close fit to the human skin, is particularly suitable for intimate apparel, bedding, and infant clothing.

[0003] However, knitted cotton fabrics have low moisture absorption and evaporation rates, resulting in poor quick-drying properties. During the drying process, moisture cannot evaporate quickly, leaving the skin damp for extended periods, causing discomfort. Furthermore, knitted cotton fabrics have low UV absorption capacity and the knitted structure is porous, allowing UV rays to easily penetrate into the fabric, resulting in poor UV resistance. Furthermore, cotton has poor thermal conductivity and cannot dissipate heat quickly, limiting its use in summer.

[0004] The above defects need to be solved urgently. Utility Model Content

[0005] In order to solve the problems of poor quick-drying property, poor UV resistance and poor heat dissipation of existing knitted cotton fabrics, the utility model provides a cool sun-proof knitted fabric.

[0006] The technical solution of this utility model is as follows:

[0007] A cool sun-proof knitted fabric, comprising cotton yarn and sun-proof yarn, wherein the cotton yarn and the sun-proof yarn are arranged alternately, the sun-proof yarn is a high-thermal-conductivity yarn such as nylon yarn or polyethylene yarn, and the sun-proof yarn is filled with nanoparticle anti-ultraviolet components such as zinc oxide or titanium dioxide;

[0008] The cotton yarn forms a plurality of first coils along the transverse direction of the fabric, and the sun-proof yarn forms a plurality of second coils along the transverse direction of the fabric, and the first coils and the second coils are sequentially interlaced with each other in the longitudinal direction of the fabric;

[0009] The first coil includes a first head, both ends of which are connected to a first tail, and the second coil includes a second head, both ends of which are connected to a second tail;

[0010] On the front side of the fabric, the second head portion is sleeved on the first tail portion; on the back side of the fabric, the first head portion is sleeved on the second tail portion.

[0011] According to the above-mentioned solution of the present invention, the yarn count of the cotton yarn is 50S.

[0012] According to the above-mentioned solution of the present invention, the material of the cotton yarn is long-staple cotton.

[0013] According to the above solution of the present invention, the fineness of the nylon yarn is 70 denier.

[0014] According to the above-mentioned solution of the present invention, the nylon yarn is composed of 48 monofilaments.

[0015] According to the above solution of the utility model, the fineness of the polyethylene yarn is 75 denier.

[0016] According to the above-mentioned solution of the utility model, the polyethylene yarn is composed of 36 monofilaments.

[0017] According to the above-mentioned solution of the present invention, the sun-proof yarn is a fully drawn yarn.

[0018] The utility model according to the above solution has the following beneficial effects:

[0019] In the above-mentioned cool sun-proof knitted fabric, cotton yarn and sun-proof yarn are alternately arranged, the sun-proof yarn is nylon yarn or polyethylene yarn, and the sun-proof yarn is filled with zinc oxide or titanium dioxide. The cotton yarn forms a plurality of first coils along the transverse direction of the fabric, and the sun-proof yarn forms a plurality of second coils along the transverse direction of the fabric. The first coils and the second coils are sequentially intertwined in the longitudinal direction of the fabric. By alternating the cotton yarn and the sun-proof yarn, the sun-proof yarn can be evenly distributed on the front and back of the fabric. Since zinc oxide or titanium dioxide has an absorption or reflection effect on ultraviolet rays, it can effectively prevent ultraviolet rays from penetrating the fabric and can play a good shielding role against ultraviolet rays, thereby improving the anti-ultraviolet performance of the knitted cotton fabric. At the same time, the nanoparticles of zinc oxide or titanium dioxide also have a high reflectivity to sunlight, which can reduce the temperature rise of the human body caused by sunlight and enhance the heat-shielding performance of the fabric.

[0020] In addition, on the front side of the fabric, the second head is sleeved on the first tail, and on the back side of the fabric, the first head is sleeved on the second tail, that is, the utility model is a double-layer fabric, so that the sun-proof yarn can be wrapped from the first layer of the fabric to the second layer of the fabric, thereby forming a continuous coil structure between the first layer and the second layer of the fabric. Since both nylon yarn and polyethylene yarn are quick-drying yarns, they can guide human sweat to the surface of the fabric for rapid volatilization, thereby improving the quick-drying performance of the fabric.

[0021] In addition, since nylon yarn and polyethylene yarn are both cool yarns with high thermal conductivity, they can enhance the cool contact performance of the fabric and improve the wearing comfort of the fabric; at the same time, nylon yarn and polyethylene yarn have strong thermal conductivity and can conduct the heat energy generated by the human body to the surface of the fabric for rapid heat dissipation, thereby improving the heat dissipation performance of the fabric.

[0029] Example 1

[0030] like Figure 1 、 Figure 2 As shown, the utility model provides a cool sun-proof knitted fabric, comprising cotton yarn 1 and sun-proof yarn 2, wherein the cotton yarn 1 and the sun-proof yarn 2 are arranged alternately, and the sun-proof yarn 2 is a nylon yarn filled with zinc oxide, and the cotton yarn 1 forms a plurality of first coils 11 along the transverse direction of the fabric, and the sun-proof yarn 2 forms a plurality of second coils 21 along the transverse direction of the fabric, and the first coils 11 and the second coils 21 are sequentially interlaced with each other in the longitudinal direction of the fabric. By alternately weaving the cotton yarn 1 and the sun-proof yarn 2, the sun-proof yarn 2 can be evenly distributed on both the front and back sides of the fabric. Since zinc oxide has a reflective and highly absorbing effect on ultraviolet rays, it can effectively prevent ultraviolet rays from penetrating the fabric, and can play a good shielding role against ultraviolet rays, thereby improving the anti-ultraviolet performance of the knitted cotton fabric. At the same time, the nanoparticles of zinc oxide also have a high reflective function for sunlight, which can reduce the temperature rise of the human body caused by sunlight and enhance the heat-shielding performance of the fabric.

[0031] In this embodiment, the first coil 11 of the cotton yarn 1 includes a first head 111, and both ends of the first head 111 are connected to the first tail 112. The second coil 21 of the nylon yarn includes a second head 211, and both ends of the second head 211 are connected to the second tail 212. On the front of the fabric, the second head 211 is sleeved on the first tail 112, and on the back of the fabric, the first head 111 is sleeved on the second tail 212. The front and back of the fabric are both the heads of the coil, that is, the present invention is a double-layer fabric, so that the sun-proof yarn 2 can be wrapped from the first layer of the fabric to the second layer of the fabric, thereby forming a continuous coil structure on the first and second layers of the fabric. Since the nylon yarn is a quick-drying yarn, it can guide the sweat of the human body to the surface of the fabric for rapid volatilization, thereby improving the quick-drying performance of the fabric.

[0032] In this embodiment, cotton yarn 1 is made of long-staple cotton and has a yarn count of 50S, meaning it is relatively fine. High-count cotton yarns create more and finer fiber interlacing points during weaving, which not only enhances the structural stability of the fabric but also improves its breathability, moisture wicking properties, and comfort. Of course, the yarn count of cotton yarn 1 can be adjusted based on actual needs. Furthermore, after weaving, the fabric undergoes a liquid ammonia finishing process to swell the cotton fibers, further improving the fabric's cool feel.

[0033] In this embodiment, the nylon yarn has a fineness of 70 denier and is filled with 4% zinc oxide. However, the fineness of the nylon yarn and the zinc oxide content can be customized according to actual needs. Furthermore, because nylon yarn is a highly thermally conductive, cooling yarn, it enhances the cool feel of the fabric and improves its wearing comfort. Furthermore, its strong thermal conductivity allows it to conduct heat generated by the human body to the fabric surface for rapid heat dissipation, improving the fabric's heat dissipation performance. Furthermore, the nylon yarn is composed of 48 monofilaments and is fully drawn yarn (FDY). By fully stretching the fibers, the molecular density and elasticity of the fibers are further enhanced, thereby ensuring the stability of the yarn and fabric. Of course, the nylon yarn can be replaced with other highly thermally conductive yarns, and the zinc oxide can be replaced with other nanoparticle anti-UV ingredients. The material of the sunscreen yarn and the nanoparticle anti-UV ingredient filled in the yarn can be customized according to actual needs.

[0034] 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.

[0035] It should be noted that yarn count (S) indicates the thickness of short fibers, and denier (D) indicates the thickness of long fibers.

[0036] When the fabric is produced, a double-sided knitting machine is used for weaving. Cotton yarn 1 and nylon yarn are woven in a 1:1 ratio. That is, the first yarn is cotton yarn 1, which is used to weave the first horizontal row of coils on the front side. The second yarn is sun-screen yarn 2, which is used to weave the first horizontal row of coils on the back side. The two yarns are circulated back and forth until the fabric is woven. After weaving is completed, a semi-bleaching process is used for dyeing and finishing, and then a liquid ammonia process is used for finishing, and finally the fabric is finalized.

[0037] Example 2

[0038] like Figure 1As shown, the utility model provides a cool sun-proof knitted fabric, comprising cotton yarn 1 and sun-proof yarn 2, wherein the cotton yarn 1 and the sun-proof yarn 2 are arranged alternately, and the sun-proof yarn 2 is a polyethylene yarn filled with titanium dioxide, and the cotton yarn 1 forms a plurality of first coils 11 along the transverse direction of the fabric, and the sun-proof yarn 2 forms a plurality of second coils 21 along the transverse direction of the fabric, and the first coils 11 and the second coils 21 are sequentially intertwined in the longitudinal direction of the fabric. By alternately weaving the cotton yarn 1 and the sun-proof yarn 2, the sun-proof yarn 2 can be evenly distributed on both sides of the fabric. Since titanium dioxide has a reflective and highly absorbing effect on ultraviolet rays, it can effectively prevent ultraviolet rays from penetrating the fabric, and can play a good shielding role against ultraviolet rays, thereby improving the anti-ultraviolet performance of the knitted cotton fabric. At the same time, the nanoparticles of titanium dioxide also have a high reflective function for sunlight, which can reduce the temperature rise of the human body caused by sunlight and enhance the heat-shielding performance of the fabric.

[0039] In this embodiment, the first coil 11 of the cotton yarn 1 includes a first head 111, and both ends of the first head 111 are connected to the first tail 112. The second coil 21 of the polyethylene yarn includes a second head 211, and both ends of the second head 211 are connected to the second tail 212. On the front of the fabric, the second head 211 is sleeved on the first tail 112, and on the back of the fabric, the first head 111 is sleeved on the second tail 212. The front and back of the fabric are both the heads of the coil, that is, the present invention is a double-layer fabric, so that the sun-proof yarn 2 can be wrapped from the first layer of the fabric to the second layer of the fabric, thereby forming a continuous coil structure on the first and second layers of the fabric. Since the polyethylene yarn is a quick-drying yarn, it can guide the sweat of the human body to the surface of the fabric for volatilization, thereby improving the quick-drying performance of the fabric.

[0040] In this embodiment, cotton yarn 1 is made of long-staple cotton and has a yarn count of 50S, meaning it is relatively fine. High-count cotton yarns create more and finer fiber interlacing points during weaving, which not only enhances the structural stability of the fabric but also improves its breathability, moisture wicking properties, and comfort. Of course, the yarn count of cotton yarn 1 can be adjusted based on actual needs. Furthermore, after weaving, the fabric undergoes a liquid ammonia finishing process to swell the cotton fibers, further improving the fabric's cool feel.

[0041] In this embodiment, the polyethylene yarn has a fineness of 75 denier and is filled with 3% titanium dioxide. Of course, in actual design, the fineness of the polyethylene yarn and the titanium dioxide content can be designed according to actual needs. Furthermore, because the polyethylene yarn is a highly thermally conductive, cooling yarn, it can enhance the cool contact properties of the fabric and improve the wearing comfort of the fabric. At the same time, the polyethylene yarn has strong thermal conductivity and can conduct heat energy generated by the human body to the surface of the fabric for rapid heat dissipation, thereby improving the heat dissipation performance of the fabric. Furthermore, the polyethylene yarn is composed of 36 monofilaments and is a fully drawn yarn (FDY). Of course, the polyethylene yarn can also be replaced with other highly thermally conductive yarns, and the titanium dioxide can also be replaced with other nanoparticle anti-UV ingredients. In actual design, the material of the sunscreen yarn and the nanoparticle anti-UV ingredient filled therein can be designed according to actual needs.

[0042] During the production of titanium dioxide-filled polyethylene yarn, titanium dioxide particles are incorporated into the polyethylene through a melt spinning process. The polyethylene is melted and extruded through spinnerets to form fibers, with the titanium dioxide 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 it, so its principles and process will not be described in detail.

[0043] When the fabric is produced, a double-sided machine is used for weaving. Cotton yarn 1 and polyethylene yarn are woven in a 1:1 ratio. That is, the first yarn is cotton yarn 1, which is used to weave the first horizontal row of coils on the front side. The second yarn is sun-screen yarn 2, which is used to weave the first horizontal row of coils on the back side. The two yarns are circulated back and forth until the fabric is woven. After weaving is completed, a semi-bleaching process is used for dyeing and finishing, and then a liquid ammonia process is used for finishing, and finally the fabric is finalized.

[0044] 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.

[0045] 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.
