Abstract
Description
Technical Field
[0001] The utility model relates to a blended yarn, in particular to a high-strength blended yarn. Background Art
[0002] Blended yarn refers to yarn spun from a mixture of two or more fibers. Currently, the main blended yarns on the market include polyester-cotton yarn (a blend of cotton and polyester), and acrylic-viscose yarn (a blend of viscose and acrylic). However, existing blended yarns are generally weak and prone to breaking during weaving, impacting production. Furthermore, existing blended yarns have poor antibacterial properties, making the fabric susceptible to bacterial growth and odor during subsequent use. Therefore, existing technologies suffer from low strength and poor antibacterial properties. Utility Model Content
[0003] The purpose of the utility model is to provide a high-strength blended yarn, which has the characteristics of being able to effectively improve strength and antibacterial effect.
[0004] The technical solution of the utility model is: a high-strength blended yarn, including mutually blended nano-antibacterial polyester fiber, a first composite fiber and a second composite fiber; the first composite fiber includes a first cotton fiber, and the first cotton fiber is spirally wound with ultra-high molecular weight polyethylene fiber and bamboo charcoal fiber in sequence; the second composite fiber includes a spandex fiber, and the spandex fiber is spirally wound with polybenzimidazole fiber and aramid fiber in sequence.
[0005] In the aforementioned high-strength blended yarn, the spiral winding directions of the bamboo charcoal fiber and the ultra-high molecular weight polyethylene fiber are opposite, and the spiral winding directions of the aramid fiber and the polybenzimidazole fiber are also opposite.
[0006] In the aforementioned high-strength blended yarn, the nano-antibacterial polyester fiber is provided with a nano-silicon dioxide coating.
[0007] In the aforementioned high-strength blended yarn, the usage ratio of the nano antibacterial polyester fiber, the first composite fiber and the second composite fiber is 2:1:1.
[0008] Compared with the prior art, the high-strength blended yarn of the present invention is a blend of nano-antibacterial polyester fiber, a first composite fiber, and a second composite fiber. Through the mutual coordination between the above-mentioned fibers, the overall strength of the yarn can be effectively improved, and the wear resistance can also be improved. Specifically, the first composite fiber is composed of a first cotton fiber and a spirally wound ultra-high molecular weight polyethylene fiber and bamboo charcoal fiber, which can not only improve the strength but also have certain antibacterial, antimicrobial and deodorizing effects; the second composite fiber is composed of a spandex fiber and a wound polybenzimidazole fiber and aramid fiber, which has a certain elasticity while also ensuring good strength and wear resistance. In summary, the present invention has the characteristics of being able to effectively improve strength and improve antibacterial effects.
[0009] In addition, applying a nano-silica coating on the outside of polyester fibers can also improve the yarn's UV resistance. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the utility model;
[0011] Figure 2 is a structural view of a first composite fiber;

DETAILED DESCRIPTION
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0015] Example. A high strength blended yarn, comprising Figure 1-3 As shown, it includes a blended nano-antibacterial polyester fiber 1, a first composite fiber 2, and a second composite fiber 3; the first composite fiber 2 includes a first cotton fiber 201, and the first cotton fiber 201 is spirally wound with an ultra-high molecular weight polyethylene fiber 202 and a bamboo charcoal fiber 203; the second composite fiber 3 includes a spandex fiber 301, and the spandex fiber 301 is spirally wound with a polybenzimidazole fiber 302 and an aramid fiber 303.
[0016] The spiral winding directions of the bamboo charcoal fibers 203 and the ultra-high molecular weight polyethylene fibers 202 are opposite to each other, and the spiral winding directions of the aramid fibers 303 and the polybenzimidazole fibers 302 are also opposite to each other.
[0017] The nano antibacterial polyester fiber 1 is provided with a nano silicon dioxide coating.
[0018] The usage ratio of the nano antibacterial polyester fiber 1, the first composite fiber 2 and the second composite fiber 3 is 2:1:1.
[0019] The spiral winding directions of the bamboo charcoal fiber and the ultra-high molecular weight polyethylene fiber are set to be opposite, and the spiral winding directions of the aramid fiber and the polybenzimidazole fiber are also set to be opposite, so that the strength of the yarn can be strengthened from different directions, further improving the strength of the blended yarn and improving the tensile properties.
[0020] Polybenzimidazole fiber also has good flexibility, which makes the blended yarn also have a certain flexibility.
[0021] Ultra-high molecular weight polyethylene fiber, also known as high-strength and high-modulus polyethylene fiber, is a fiber spun from polyethylene with a molecular weight of 1 million to 5 million.
[0022] The production process of the utility model is as follows: first, a first composite yarn and a second composite yarn are separately produced; a layer of nano-silicon dioxide coating is impregnated and adhered to the surface of the nano-antibacterial polyester fiber; after drying, the first composite yarn, the antibacterial polyester fiber and the second composite yarn are blended together in a blending manner to obtain a high-strength blended yarn product.
[0023] The preparation process of the first composite yarn is as follows: a layer of ultra-high molecular weight polyethylene fiber is spirally wound on the surface of the first cotton fiber, and then a layer of bamboo charcoal fiber is spirally wound in the opposite direction outside the ultra-high molecular weight polyethylene fiber to obtain the first composite yarn.
[0024] The preparation process of the second composite yarn is as follows: a layer of polybenzimidazole fiber is spirally wound on the surface of the spandex fiber, and then a layer of aramid fiber is spirally wound in the opposite direction outside the polybenzimidazole fiber to obtain the second composite yarn.
