Description

Technical Field

[0001] This utility model relates to the field of blended fiber filament technology, and in particular to a different colored slub-joint blended fiber filament. Background Technology

[0002] Blended filaments refer to filaments made by mixing two or more different fiber components. Blended filaments have a variety of properties, and skin-friendliness is one of them. Good skin-friendliness can reduce skin irritation and improve comfort when wearing them.

[0003] Chinese utility model patent CN221645183U discloses an antistatic flexible fiber yarn, comprising acrylic fibers that have undergone low-temperature carbonization treatment. An antistatic layer is provided on the outer surface of the acrylic fibers. Several acrylic fibers are provided, and the several acrylic fibers are intertwined to form an inner core. An air-permeable layer is provided on the outer layer of the inner core. A skin-friendly layer is provided on the outside of the air-permeable layer, which is a fiber layer formed by several mixed filaments spirally wound on the outside of the air-permeable layer. The mixed filaments are a mixed fiber formed by spirally winding bamboo fiber, hemp fiber and milk protein fiber.

[0004] The outermost layer of the existing fiber yarn is a skin-friendly layer formed by spiral winding of bamboo fiber, hemp fiber and milk protein fiber. However, the natural knots and irregular textures on the surface of hemp fiber can cause itching when worn, and bamboo fiber can cause pilling when worn, thus reducing the skin-friendliness of the fiber yarn. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a heterochromatic bamboo-joint blended filament.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heterochromatic slub-joint blended filament comprising a core layer composite fiber, wherein the core layer composite fiber comprises polyester pre-oriented yarn, cotton composite fiber is spirally wound on the sidewall of the polyester pre-oriented yarn, soybean protein composite fiber is spirally wound on the cotton composite fiber, and a graphene layer is coated on the soybean protein composite fiber.

[0007] By adopting the above technical solution, soybean protein composite fiber, which shares characteristics with hemp fiber, bamboo fiber, and milk protein fiber, is coated with a graphene layer. This graphene layer possesses excellent antibacterial, antistatic, and skin-friendly properties, preventing itching or pilling, thus improving the comfort of the product after it is made from the blended filaments. Furthermore, the high elasticity of the pre-oriented polyester yarn enhances the elasticity of the blended filaments.

[0008] Furthermore, the cotton composite fiber is spirally wound with polyester composite fibers that are misaligned with the soybean protein composite fiber, and the polyester composite fiber is also coated with a graphene layer. The soybean protein composite fiber is formed by twisting two soybean protein fibers together, and the polyester composite fiber is formed by twisting two polyester fibers together.

[0009] Furthermore, the diameter of the cross-section of the polyester composite fiber is larger than the diameter of the cross-section of the soybean protein composite fiber.

[0010] By adopting the above technical solution, since the diameter of the cross-section of polyester composite fiber is larger than that of soybean protein composite fiber, the contact area between the fabric made of blended filaments and the skin is reduced when worn, thus improving the breathability of the blended filaments.

[0011] Furthermore, the sidewall of the polyester pre-oriented yarn is spirally wound with a plurality of nylon fibers that are staggered with the cotton composite fibers. The diameter of the cross-section of the plurality of nylon fibers is larger than the diameter of the cross-section of the cotton composite fibers. The inner sides of the soybean protein composite fibers and the inner sides of the polyester composite fibers are both in contact with the nylon fibers.

[0012] By adopting the above technical solution, since the diameter of the cross-section of multiple nylon fibers is larger than that of the cross-section of cotton composite fibers, the inner side of soybean protein composite fibers and the inner side of polyester composite fibers are in contact with nylon fibers, which creates cavities between soybean protein composite fibers, polyester composite fibers and nylon fibers, which is more conducive to air flow and improves the air permeability of blended filaments.

[0013] Furthermore, the core layer composite fiber also includes a modified polyester composite fiber with high elasticity disposed within the polyester pre-oriented yarn, wherein the modified polyester composite fiber is formed by twisting two modified polyester fibers together.

[0014] By adopting the above technical solution, the probability of affecting the overall elasticity of the core layer composite fiber is reduced while enhancing the overall strength of the core layer composite fiber.

[0015] Furthermore, the cotton composite fiber is formed by two cotton fibers winding together, and the distance between the two bent segments of the cotton fibers is 30 nm.

[0016] By adopting the above technical solution, the probability of affecting the overall air permeability of cotton composite fibers when the number of cotton composite fibers increases is reduced.

[0017] Furthermore, the spiral winding direction of the polyester composite fiber is the same as that of the soybean protein composite fiber, the spiral winding direction of the nylon fiber is the same as that of the cotton composite fiber, and the spiral winding direction of the polyester composite fiber is opposite to that of the cotton composite fiber.

[0018] By adopting the above technical solution, the probability of polyester composite fiber and soybean protein composite fiber sticking to cotton composite fiber when they are wrapped together is reduced.

[0019] Furthermore, the soybean protein fiber has a hollow structure with openings at both ends.

[0020] By adopting the above technical solutions, the elasticity and breathability of soybean protein fiber have been improved.

[0021] In summary, this utility model has the following beneficial effects: In this application, because the soybean protein composite fiber possesses the common characteristics of hemp fiber, bamboo fiber, and milk protein fiber, and is coated with a graphene layer, the graphene layer has excellent antibacterial, antistatic, and skin-friendly properties, preventing itching or pilling, thereby improving the comfort of wearing the product made from the blended filaments. Furthermore, the high elasticity of the pre-oriented polyester yarn enhances the elasticity of the blended filaments. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-2As shown in the embodiment of this application, a heterochromatic slub-fiber blended filament is disclosed, comprising a core composite fiber 1, a cotton composite fiber 2, a soybean protein composite fiber 3, and a graphene layer. The core composite fiber 1 comprises a polyester pre-oriented yarn 11 and a modified polyester composite fiber 12 (the modified polyester composite fiber 12 is a highly elastic composite yarn made from bicomponent polyester filaments through heat treatment and stretching, utilizing their high and low viscosity characteristics). The modified polyester composite fiber 12 is disposed within the polyester pre-oriented yarn 11 and possesses high elasticity. The soybean protein composite fiber 3 is formed by twisting two soybean protein fibers together, and the polyester composite fiber 4 is formed by twisting two polyester fibers together. The cotton composite fiber 2 is spirally wound onto the sidewall of the polyester pre-oriented yarn 11, the soybean protein composite fiber 3 is spirally wound onto the cotton composite fiber 2, and the graphene layer is coated onto the soybean protein composite fiber 3.

[0027] Because soybean protein composite fiber 3 possesses characteristics shared by hemp fiber, bamboo fiber, and milk protein fiber, and is coated with a graphene layer, this fiber exhibits excellent antibacterial, antistatic, and skin-friendly properties, preventing itching or pilling and thus improving the comfort of wearing products made from the blended filaments. Furthermore, the core layer composite fiber 1 is composed of modified polyester composite fiber 12 and polyester pre-oriented yarn 11, which improves the core layer composite fiber 1 while reducing the probability of affecting its elasticity.

[0028] A polyester composite fiber 4, staggered from the soybean protein composite fiber 3, is spirally wound onto the cotton composite fiber 2. The polyester composite fiber 4 is also coated with a graphene layer. The soybean protein composite fiber 3 is formed by twisting two soybean protein fibers together, and the polyester composite fiber 4 is formed by twisting two polyester fibers together. The diameter of the cross-section of the polyester composite fiber 4 is larger than that of the soybean protein composite fiber 3. Because the diameter of the cross-section of the polyester composite fiber 4 is larger than that of the soybean protein composite fiber 3, the contact area between the fabric made of blended filaments and the skin is reduced during wear, thus improving the breathability of the blended filaments.

[0029] Since the diameter of the cross-section of multiple nylon fibers 5 is larger than that of the cross-section of cotton composite fiber 2, the inner side of soybean protein composite fiber 3 and the inner side of polyester composite fiber 4 are in contact with nylon fibers 5, which creates a cavity between soybean protein composite fiber 3 and polyester composite fiber 4 and nylon fiber 5, which is more conducive to air flow and improves the air permeability of the blended filaments. Before the cotton composite fiber 2, soybean protein composite fiber 3, polyester composite fiber 4, and nylon fiber 5 are made, low-melting-point thermoplastic fibers are uniformly mixed into the raw materials of cotton composite fiber 2, soybean protein composite fiber 3, polyester composite fiber 4, and nylon fiber 5 respectively. After the cotton composite fiber 2, soybean protein composite fiber 3, polyester composite fiber 4, and nylon fiber 5 are made into filaments and wound, the cotton composite fiber 2, soybean protein composite fiber 3, polyester composite fiber 4, and nylon fiber 5 are heated in sequence according to the winding order in a hot air dryer to melt the low-melting-point thermoplastic fibers. Finally, the melted thermoplastic fibers are cooled and solidified, thereby fixing the cotton composite fiber 2, soybean protein composite fiber 3, polyester composite fiber 4, and nylon fiber 5.

[0030] Multiple nylon fibers 5 are spirally wound on the side wall of the polyester pre-oriented yarn 11, which are all misaligned with the cotton composite fiber 2. The diameter of the cross-section of the multiple nylon fibers 5 is larger than the diameter of the cross-section of the cotton composite fiber 2. The inner side of the soybean protein composite fiber 3 and the inner side of the polyester composite fiber 4 are both in contact with the nylon fibers 5.

[0031] Cotton composite fiber 2 is formed by two cotton fibers twisted together, with a distance of 30nm between the bent sections of the two cotton fibers. This reduces the probability of affecting the overall breathability of cotton composite fiber 2 when the number of cotton composite fibers 2 increases.

[0032] The spiral winding direction of polyester composite fiber 4 is the same as that of soybean protein composite fiber 3, the spiral winding direction of nylon fiber 5 is the same as that of cotton composite fiber 2, and the spiral winding direction of polyester composite fiber 4 is opposite to that of cotton composite fiber 2. This reduces the probability of polyester composite fiber 4 and soybean protein composite fiber 3 adhering to cotton composite fiber 2 during their winding.

[0033] Soy protein fiber has a hollow structure with openings at both ends. This improves the elasticity and breathability of soybean protein fiber.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
