Description

Technical Field

[0001] This utility model relates to the field of core-wound yarn technology, specifically to a core-wound elastic antibacterial and abrasion-resistant yarn. Background Technology

[0002] The functionality of yarn is determined by the materials used and the weaving structure. Common structures include core-spun and wrapped yarns. A core-spun structure consists of a core yarn at the center and a sheath yarn acting as the outer sheath fiber, arranged in the same direction. A wrapped structure consists of the sheath yarn acting as the outer sheath fiber, spirally wrapped around the core yarn at the center. Core-spun and wrapped structures are a relatively new spinning technology that has been widely used in the production of high-strength, abrasion-resistant training uniform yarns. This technology involves feeding two combined filaments and a short roving onto a spinning machine, forming a structure where one filament and the short roving are core-spun, and the other filament is wrapped around the outside. This effectively improves the yarn's strength and abrasion resistance. However, the single short roving in the yarn results in an excessively high filament content, leading to fabrics with good elasticity but a strong synthetic feel and poor comfort.

[0003] Sirospinning, a widely used traditional spinning technique, can be applied to core-spun and wrapped structures. Specifically, two rovings with a certain distance between them are fed into a spinning frame. After drafting, these two single yarn slivers are output by the front roller. Due to the transmission of twist, the single yarn slivers acquire a small amount of twist. After being combined, they are further twisted into a yarn similar to a ply, and then wound onto a bobbin. The advantage of this spinning technique is that the double rovings can produce a wider range of yarn components, meeting the requirements for composite production of different fabric components. However, it cannot be combined into filaments; it can only spin pure short-fiber yarns. While the spun yarns are relatively comfortable, they are weaker and have poor abrasion resistance.

[0004] As living standards improve, people are increasingly demanding healthier textiles. To enhance antibacterial properties, manufacturers add antibacterial materials. However, traditional methods of treating these materials with silver ions and other metal ions may result in the leaching of heavy metals, which can be harmful to the human body. Furthermore, the antibacterial ability decreases after repeated washing, making the antibacterial performance short-lived. In certain specialized fields, such as outdoor sports, where usage scenarios are relatively complex and demanding, consumers have higher requirements for the elasticity, antibacterial properties, and abrasion resistance of textile materials. Therefore, continuous material updates are necessary. Utility Model Content

[0005] This invention provides a core-wound elastic antibacterial and wear-resistant yarn, which solves the problem that existing yarns are functionally insufficient and cannot meet the market's demand for elastic, antibacterial and wear-resistant textile materials.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A core-spun elastic antibacterial and abrasion-resistant yarn includes a core-spun structure at the center and an outer wrapping structure. The core-spun structure includes a polyester filament core layer (1) as the yarn core and an outer cotton-polyester core-spun layer (2). The wrapping structure includes a hemp antibacterial secondary wrapping layer (3) wrapped around the cotton-polyester core-spun layer (2) and an outermost nylon filament wrapping layer (4).

[0008] The raw material of the polyester filament core layer (1) is bicomponent elastic polyester filament.

[0009] The raw material for the cotton-polyester core layer (2) is a blended yarn of moisture-wicking and quick-drying polyester and cotton.

[0010] The raw material of the hemp antibacterial secondary coating layer (3) is hemp fiber.

[0011] The raw material of the nylon filament wrapping layer (4) is high-strength wear-resistant nylon filament.

[0012] In this preferred embodiment, the polyester filament core layer and the cotton-polyester core-spun layer form a composite core-spun structure. First, cotton and moisture-wicking, quick-drying polyester are blended to create a roving, resulting in a soft hand feel and good moisture-wicking properties. Then, this roving is stretched and lengthened using a core-spun yarn winding device to wrap the bicomponent elastic polyester filament, initially forming a cotton-polyester core-spun structure with the polyester filament core layer enclosing the cotton-polyester filament. The bicomponent elastic polyester filament inside provides support for the overall yarn and imparts a certain degree of elasticity; the cotton-polyester core layer on the outside gives the yarn a soft hand feel and good moisture-wicking properties.

[0013] After the cotton-polyester filament core-spun structure of the polyester filament core layer (1) and the cotton-polyester core-spun layer (2) is formed, the hemp antibacterial secondary wrapping layer (3) is tightly wrapped around the core-spun structure. The material of the hemp antibacterial secondary wrapping layer is bio-based antibacterial treated hemp fiber. First, cotton and hemp fibers are made into rovings, and then twisted and wound around the cotton-polyester filament core-spun structure by a core-spun yarn wrapping device. In the design process, the hemp antibacterial secondary wrapping layer is the outermost layer of the yarn and is tightly wrapped around the cotton-polyester core-spun layer to form a core-spun Sirospun structure. Relying on the better abrasion resistance, moisture absorption and antibacterial properties of hemp fiber, the outer layer of the yarn that comes into contact with the skin and the environment has better abrasion resistance and antibacterial properties. The wrapping structure can also further improve the yarn strength and solve the problems of low strength and poor spinnability of core-spun yarn.

[0014] Finally, outside the core-spun Siro-spun structure, high-strength, abrasion-resistant nylon filaments are wrapped around the core-spun Siro-spun structure in a relatively sparse manner using a core-spun winding yarn machine, adjusting the filament tension and feeding speed. This creates a new type of structural yarn combining a core-spun and wrapped structure with a Siro-spun structure. The outermost layer of high-strength, abrasion-resistant nylon filaments further enhances the yarn's strength, abrasion resistance, and antibacterial properties. Simultaneously, the relatively sparse winding structure allows the hemp antibacterial secondary wrapping layer to be exposed, reducing the synthetic feel of the yarn and improving the wearing comfort of subsequent fabrics and garments.

[0015] Furthermore, the bicomponent elastic polyester filament is a semi-dull 30D / 24F white bicomponent elastic polyester filament T800.

[0016] This preferred solution utilizes bicomponent elastic polyester filament T800, a novel type of elastic fiber. Generally, to achieve good elasticity and elastic recovery, spandex filament needs to be added to yarn or fabric. However, spandex has drawbacks such as poor heat resistance, easy aging and discoloration, poor dyeing performance, and high cost, which restricts the selection of subsequent weaving and dyeing processes. Bicomponent elastic polyester filament T800, on the other hand, is a specially treated elastic polyester filament that achieves good elasticity without the addition of spandex, and its cost is lower than that of spandex, effectively avoiding a series of dyeing and processing problems caused by spandex in yarn.

[0017] Furthermore, the raw materials for the moisture-wicking and quick-drying polyester and cotton blended yarn are long-staple cotton and polyester, wherein, by weight, the proportions of each component are as follows: long-staple cotton 30-60%, polyester 40-70%.

[0018] In this preferred embodiment, long-staple cotton and polyester are mixed in a specific ratio, giving the material both moisture-wicking and quick-drying properties.

[0019] Furthermore, hemp fibers have a length of 16-20mm, while long-staple cotton has a length of 20-40mm.

[0020] In this preferred embodiment, hemp fiber molecules contain a large number of polar hydrophilic groups, which readily combine with water molecules upon contact and adsorb them. Furthermore, due to the unique structure of hemp fibers, the fiber center has a large cavity with numerous longitudinally connected slits and pores, giving the fiber numerous capillary channels. This allows for the rapid transfer and diffusion of moisture and water vapor within the fabric. When the body sweats, these structures in hemp fabric can promptly guide sweat or moisture to the fabric surface, thereby dissipating it into the air and keeping the skin dry. Its sweat absorption rate is twice that of commonly used cotton fabrics. In addition, hemp fibers also contain cannabinoid antibacterial substances, which can inhibit the metabolic and physiological activities of mold; even trace amounts of cannabinoids can kill mold microorganisms.

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] (1) In this utility model, the polyester filament core layer and the cotton-polyester core layer are a composite core-spun structure. First, cotton and moisture-wicking quick-drying polyester are blended to form a roving, which has a soft hand feel and good moisture-wicking and quick-drying properties. Then, the roving is stretched and lengthened using a core-spun yarn wrapping device to wrap the bicomponent elastic polyester filament, initially forming a cotton-polyester core-spun structure with the polyester filament core layer wrapping the cotton-polyester filament on the outside. The bicomponent elastic polyester filament inside provides support for the overall yarn and gives the yarn a certain elasticity; the cotton-polyester core layer on the outside gives the yarn a soft hand feel and good moisture-wicking properties.

[0023] After the cotton-polyester filament core layer and cotton-polyester core layer are formed, a hemp antibacterial secondary wrapping layer is tightly wound around the outside of the core structure. The hemp antibacterial secondary wrapping layer material is bio-based antibacterial treated hemp fiber. First, cotton and hemp fibers are made into rovings, and then twisted and wound around the outside of the cotton-polyester filament core structure using a core-spun yarn equipment. In the design process, the hemp antibacterial secondary wrapping layer is the outermost layer of the yarn and is tightly wound around the outside of the cotton-polyester core layer to form a core-spun Sirospun structure. Relying on the better abrasion resistance, moisture absorption, and antibacterial properties of hemp fiber, the outer layer of the yarn that comes into contact with the skin and the environment has better abrasion resistance and antibacterial properties. The wrapping structure can also further improve the yarn strength and solve the problems of low strength and poor spinnability of core-spun yarn.

[0024] Finally, outside the core-spun Siro-spun structure, high-strength, abrasion-resistant nylon filaments are wrapped around the core-spun Siro-spun structure in a relatively sparse manner using a core-spun winding yarn machine, adjusting the filament tension and feeding speed. This creates a new type of structural yarn combining a core-spun and wrapped structure with a Siro-spun structure. The outermost layer of high-strength, abrasion-resistant nylon filaments further enhances the yarn's strength, abrasion resistance, and antibacterial properties. Simultaneously, the relatively sparse winding structure allows the hemp antibacterial secondary wrapping layer to be exposed, reducing the synthetic feel of the yarn and improving the wearing comfort of subsequent fabrics and garments.

[0025] (2) In this utility model, the bicomponent elastic polyester filament T800 is a new type of elastic fiber. Generally speaking, to obtain good elasticity and elastic recovery, it is necessary to add spandex filament to the yarn or fabric. However, spandex has disadvantages such as poor heat resistance, easy aging and discoloration, poor dyeing performance, and high cost, which restricts the selection of weaving and dyeing processes for subsequent products. The bicomponent elastic polyester filament T800 is a specially treated elastic polyester filament that can have good elasticity without adding spandex, and its cost is lower than that of spandex, effectively avoiding a series of dyeing and processing problems caused by spandex in the yarn.

[0026] (3) In this invention, long-staple cotton and polyester are mixed in a specific ratio to give the material both moisture absorption and quick-drying properties. Hemp fiber molecules contain a large number of polar hydrophilic groups, which easily combine with water molecules and adsorb water molecules when in contact with water. In addition, due to the unique structure of hemp fiber, the fiber center has a large cavity with many longitudinally connected cracks and pores, giving the fiber a large number of capillary channels, which can quickly transfer and diffuse moisture and water vapor in the fabric. When the human body sweats, these structures in hemp fabric can timely guide sweat or moisture to the fabric surface and then dissipate into the air, keeping the skin dry. Its sweat absorption rate is twice that of commonly used cotton fabric. In addition, hemp fiber also contains hemp phenolic antibacterial substances, which can inhibit the metabolism and physiological activities of fungi. Even trace amounts of hemp phenolic substances can kill fungal microorganisms.

[0027] (4) The core-wound elastic antibacterial and wear-resistant yarn obtained by this utility model combines the core-wound structure and the Sirospun structure. The final yarn has good antibacterial properties, moisture absorption and quick-drying properties, wear resistance and high breaking strength, elasticity and good elastic recovery. It solves the problem that the existing yarn cannot meet the market's needs for elastic antibacterial and wear-resistant textile materials and has good application prospects.

Figures 1-2As shown, this utility model embodiment provides a core-spun and wrapped elastic antibacterial and abrasion-resistant yarn, including a core-spun structure at the center and an outer wrapping structure.

The polyester filament core layer 1 is made of bicomponent elastic polyester filament, the cotton-polyester core-spun layer 2 is made of moisture-wicking and quick-drying polyester and cotton blended yarn, the hemp antibacterial secondary wrapping layer 3 is made of hemp fiber, and the nylon filament wrapping layer 4 is made of high-strength and abrasion-resistant nylon filament. The bicomponent elastic polyester filament is a semi-dull 30D / 24F white bicomponent elastic polyester filament T800.

The length of hemp fiber is 16-20mm, and the length of long-staple cotton is 20-40mm.

[0033] In this invention, the polyester filament core layer 1 and the cotton-polyester core-sleeving layer 2 form a composite core-sleeving structure. First, cotton and moisture-wicking polyester are blended to create a roving, resulting in a soft hand feel and good moisture-wicking properties. Then, this roving is stretched using a core-sleeving yarn wrapping device to encase the bicomponent elastic polyester filament, initially forming a core-sleeving structure with the cotton-polyester core-sleeving layer 2 on the outside and the polyester filament core layer 1 encasing the cotton-polyester filament. The bicomponent elastic polyester filament inside provides support for the overall yarn and imparts a certain degree of elasticity; the cotton-polyester core-sleeving layer on the outside gives the yarn a soft hand feel and good moisture-wicking properties.

[0034] After the cotton-polyester filament core layer and cotton-polyester core layer are formed, a hemp antibacterial secondary wrapping layer is tightly wound around the outside of the core structure. The hemp antibacterial secondary wrapping layer material is bio-based antibacterial treated hemp fiber. First, cotton and hemp fibers are made into rovings, and then twisted and wound around the outside of the cotton-polyester filament core structure using a core-spun yarn equipment. In the design process, the hemp antibacterial secondary wrapping layer is the outermost layer of the yarn and is tightly wound around the outside of the cotton-polyester core layer to form a core-spun Sirospun structure. Relying on the better abrasion resistance, moisture absorption, and antibacterial properties of hemp fiber, the outer layer of the yarn that comes into contact with the skin and the environment has better abrasion resistance and antibacterial properties. The wrapping structure can also further improve the yarn strength and solve the problems of low strength and poor spinnability of core-spun yarn.

[0035] Finally, outside the core-spun Siro-spun structure, high-strength, abrasion-resistant nylon filaments are wrapped around the core-spun Siro-spun structure in a relatively sparse manner using a core-spun winding yarn machine, adjusting the filament tension and feeding speed. This creates a new type of structural yarn combining a core-spun and wrapped structure with a Siro-spun structure. The outermost layer of high-strength, abrasion-resistant nylon filaments further enhances the yarn's strength, abrasion resistance, and antibacterial properties. Simultaneously, the relatively sparse winding structure allows the hemp antibacterial secondary wrapping layer to be exposed, reducing the synthetic feel of the yarn and improving the wearing comfort of subsequent fabrics and garments.

Generally, to obtain good elasticity and elastic recovery, spandex filament needs to be added to the yarn or fabric. However, spandex has disadvantages such as poor heat resistance, easy aging and discoloration, poor dyeing performance, and high cost, which restricts the selection of subsequent weaving and dyeing processes. Bicomponent elastic polyester filament T800, on the other hand, is a specially treated elastic polyester filament that achieves good elasticity without the addition of spandex, and its cost is lower than that of spandex, effectively avoiding a series of dyeing and processing problems caused by spandex in yarn.

Furthermore, due to the unique structure of hemp fibers, the fiber center has a large cavity with numerous longitudinally connected slits and pores, creating numerous capillary channels that allow for rapid transfer and diffusion of moisture and water vapor within the fabric.

Its sweat-wicking rate is twice that of commonly used cotton fabrics. In addition, hemp fibers contain cannabinoid antibacterial substances, which can inhibit the metabolic and physiological activities of mold; even trace amounts of cannabinoids can kill mold microorganisms.
