Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing and accessories technology, and more specifically, to a core-spun yarn and clothing. Background Technology
[0002] To improve clothing comfort, existing technologies typically involve directly incorporating active particles into spinning solutions or coating solutions to prepare functional yarns. However, when these functional yarns are made into garments, the active particles are easily shed due to friction or washing, resulting in poor durability of the functional yarn. Furthermore, the addition of active particles to the functional yarn affects its softness, thereby impacting the comfort of the garment. Utility Model Content
[0003] The present invention aims to solve one of the above-mentioned problems in the prior art by providing a core-spun yarn and garment. The core-spun yarn can improve the stability of active particles and maintain the softness of the core-spun yarn, which is beneficial to improving the comfort of the garment.
[0004] To address the aforementioned problems, the first aspect of this utility model provides a core-spun yarn, comprising: a core layer, a functional layer, and an outer sheath layer, wherein the functional layer covers the outside of the core layer, and the outer sheath layer covers the outside of the functional layer;
[0005] The functional layer includes functional yarns and viscose fibers, with a hot melt adhesive layer disposed between the functional yarns and viscose fibers. The hot melt adhesive layer is bonded to the functional yarns and viscose fibers on opposite sides, and the functional yarns contain active particles.
[0006] The viscose fiber is in contact with the core layer, and the functional yarn is in contact with the outer sheath layer.
[0007] Furthermore, the functional layer is spirally wound around the outside of the core layer, and the outer sheath layer is spirally wound around the outside of the functional layer.
[0008] Furthermore, the functional layer is spirally wound around the outside of the core layer at a first preset angle, and the outer sheath layer is spirally wound around the outside of the functional layer at a second preset angle, with the spiral winding direction of the functional layer being opposite to that of the spiral winding direction of the outer sheath layer.
[0009] Furthermore, the first preset angle is 35° to 45°, and the second preset angle is 50° to 60°.
[0010] Furthermore, the core layer is an elastic fiber, and the outer sheath layer is a natural fiber; the elastic fiber includes spandex, and the natural fiber includes at least one of cotton and wool;
[0011] The functional yarns include yarns with temperature and humidity regulating functions.
[0012] The second aspect of this utility model provides a garment comprising the core-spun yarn as described in the first aspect.
[0013] Furthermore, the garment includes a composite yarn, which is formed by twisting the core-spun yarn and synthetic fibers together, the synthetic fibers including nylon.
[0014] Furthermore, the garment includes a bodice, collar, and sleeves sewn together, the bodice being formed by sewing together a front piece and a back piece, the two sleeves being attached to both sides of the bodice, and the collar being attached to the upper end of the bodice;
[0015] The garment body, collar, and sleeves are all woven from the composite yarn.
[0016] Furthermore, the sleeves have elastically tightened cuffs, the collar is an elastically tightened collar, and the lower end of the garment has an elastically tightened hem.
[0017] Furthermore, the distance between the functional layer and the skin is 0.1 mm to 0.3 mm.
[0018] The core-spun yarn and garment described in this invention utilize a functional layer covering the outside of the core layer, with an outer sheath layer covering the outside of the functional layer. The functional layer is positioned between the core and outer sheath layers. The outer sheath layer protects the functional layer, reducing the likelihood of active particles shedding from the functional layer. It also prevents direct contact between the active particles and the skin, improving the comfort of the core-spun yarn against the skin. The core layer provides elastic support, giving the core-spun yarn a certain degree of deformation capability. The functional yarn and viscose fiber in the functional layer are bonded together with a hot-melt adhesive layer, forming a three-layer composite structure. This further reduces the shedding rate of active particles from the functional yarn and decreases its stiffness, improving its softness. Furthermore, the contact between the functional yarn and the outer sheath layer ensures that the active particles are positioned at an appropriate distance from the core-spun yarn, enhancing their efficiency in regulating temperature and humidity. The core-spun yarn provided in this invention can achieve efficient utilization and long-term fixation of active particles, and can also improve the mechanical properties of the core-spun yarn. In addition, the core-spun yarn has both durability and comfort. The active particle shedding rate of the core-spun yarn is less than 10%, and the hardness is only increased by 8%, while the active particle shedding rate of existing functional yarns is higher than 40%, and the hardness is increased by 35%.

[0024] Related technologies involve directly incorporating active particles into spinning solutions or coating solutions to prepare functional yarns, thereby regulating temperature and humidity and improving clothing comfort. However, the uneven dispersion of active particles within the functional yarn affects its temperature and humidity regulation. Furthermore, the weak bonding between active particles and fibers makes them prone to shedding due to friction or washing (shedding rate >40%), resulting in poor yarn durability. Additionally, adhesives are typically used to fix the active particles, which can harden the yarn and sacrifice its softness and breathability. Moreover, if the active particles are located on the surface of the yarn, direct skin contact can easily cause itching, and the particles are more likely to detach. If the active particles are deeply embedded within the yarn, moisture cannot reach them, affecting their regulating efficiency. All these factors negatively impact clothing comfort.
[0025] In order to solve one of the above-mentioned problems in the prior art, this utility model provides a core-spun yarn and garment. The core-spun yarn can improve the stability of active particles and maintain the softness of the core-spun yarn, which is beneficial to improving the comfort of the garment.

[0027] In this specification, the term "based on the above embodiments" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one preferred embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0028] Combination Figures 1 to 3 As shown, the first aspect of this embodiment provides a core-spun yarn, including: a core layer 10, a functional layer 20 and an outer sheath layer 30, wherein the functional layer 20 covers the outside of the core layer 10 and the outer sheath layer 30 covers the outside of the functional layer 20.
[0029] The functional layer 20 includes functional yarn 21 and viscose fiber 23. A hot melt adhesive layer 22 is disposed between the functional yarn 21 and the viscose fiber 23. The opposite sides of the hot melt adhesive layer 22 are respectively bonded to the functional yarn 21 and the viscose fiber 23. The functional yarn 21 contains active particles.
[0030] Viscose fiber 23 is in contact with core layer 10, and functional yarn 21 is in contact with outer sheath layer 30.
[0031] The core-spun yarn provided in this embodiment has a functional layer covering the outside of the core layer, and an outer sheath layer covering the outside of the functional layer. The functional layer is positioned between the core layer and the outer sheath layer. The outer sheath layer protects the functional layer, reducing the probability of active particles shedding from the functional layer. It also prevents direct contact between the active particles and the skin, improving the comfort of the core-spun yarn against the skin. The core layer provides elastic support, giving the core-spun yarn a certain degree of deformation capability. The functional yarn and viscose fiber in the functional layer are bonded together with a hot-melt adhesive layer, forming a three-layer composite structure. This further reduces the shedding rate of active particles from the functional yarn and reduces its stiffness, improving its softness. Furthermore, the contact between the functional yarn and the outer sheath layer ensures that the active particles are positioned at an appropriate distance from the core-spun yarn, which helps improve the efficiency of the active particles in regulating temperature and humidity. The core-spun yarn provided in this embodiment can achieve efficient utilization and long-term fixation of active particles, and can also improve the mechanical properties of the core-spun yarn. In addition, the core-spun yarn has both durability and comfort. The active particle shedding rate of the core-spun yarn is less than 10%, and the hardness is only increased by 8%, while the active particle shedding rate of existing functional yarns is higher than 40%, and the hardness is increased by 35%.
[0032] Based on the above embodiments, as an optional implementation method, combined with Figure 2 and Figure 3 As shown, the functional layer 20 is spirally wound around the outside of the core layer 10, and the outer sheath layer 30 is spirally wound around the outside of the functional layer 20. Therefore, the spiral winding of the functional layer 20 around the outside of the core layer 10 and the spiral winding of the outer sheath layer 30 around the outside of the functional layer 20 not only helps to improve the density of the core-spun yarn, thereby enhancing its strength and mechanical properties, but also allows the functional layer 20 to directly contact moisture through the gap between the two turns of the outer sheath layer 30, achieving its regulatory function without needing to penetrate the core layer 10 or the outer sheath layer 30. This improves the efficiency of the functional layer 20 in regulating temperature and humidity.
[0033] Based on the above embodiments, as an optional implementation, the functional layer 20 is spirally wound around the outside of the core layer 10 at a first preset angle, and the outer sheath layer 30 is spirally wound around the outside of the functional layer 20 at a second preset angle, with the spiral winding direction of the functional layer 20 opposite to that of the outer sheath layer 30. In some embodiments, the functional layer 20 is spirally wound around the outside of the core layer 10 in the forward direction at the first preset angle, and the outer sheath layer 30 is spirally wound around the outside of the functional layer 20 in the reverse direction at the second preset angle. It is understood that the functional layer 20 spirally wound around the core layer 10 at a first preset angle means that the functional layer 20, as the spiral line, gradually unfolds in a clockwise direction (viewed from above) and covers the outside of the core layer 10, with the functional layer 20 and the core layer 10 forming an inclination angle with the first preset angle; the outer sheath layer 30 spirally wound around the functional layer 20 at a second preset angle means that the outer sheath layer 30, as the spiral line, gradually unfolds in a counterclockwise direction (viewed from above) and covers the functional layer 20, with the outer sheath layer 30 and the core layer 10 forming an inclination angle with the second preset angle. Of course, in other embodiments, the functional layer 20 spirally wound around the core layer 10 at a first preset angle in a counterclockwise direction, and the outer sheath layer 30 spirally wound around the functional layer 20 at a second preset angle in a forward direction. In this embodiment, by setting the spiral winding direction of the functional layer 20 to be opposite to the spiral winding direction of the outer sheath layer 30, the core layer 10, the functional layer 20 and the outer sheath layer 30 can be firmly connected together in the form of mechanical interlocking. This not only helps to further improve the firmness of the active particles in the functional layer 20, but also reduces the slip ratio between adjacent layers, reducing the slip ratio between adjacent layers in the prior art from more than 8% to less than 2%.
[0034] Based on the above embodiments, as an optional implementation, the first preset angle is 35° to 45°, and the second preset angle is 50° to 60°. Therefore, the first and second preset angles being within the above ranges are beneficial for further improving the stability of the connection between the core layer 10, the functional layer 20, and the outer sheath layer 30, and for improving the strength and mechanical properties of the core-spun yarn.
[0035] Based on the above embodiments, as an optional implementation, the core layer 10 is made of elastic fiber, and the outer sheath layer 30 is made of natural fiber; wherein, the elastic fiber includes spandex, and the natural fiber includes at least one of cotton and wool. The core layer 10, made of elastic fiber, provides elastic support, giving the core-spun yarn a certain degree of deformation capability. The outer sheath layer 30, made of natural fiber, is in direct contact with the skin, which helps improve comfort. The functional yarn 21 can be a yarn made using 37.5TM technology, derived from the functional yarn developed by Cocona, which transforms volcanic rock minerals that have undergone special high-temperature nano-treatment into active particles embedded in the yarn. The yarn made using 37.5TM technology in the functional layer 20 can regulate temperature and humidity, improving the comfort of the clothing. Of course, those skilled in the art can also replace the functional yarn with functional yarns with other functions (such as antibacterial or UV protection) according to actual needs.
[0036] In this embodiment, the hot melt adhesive layer 22 can be selected from the hot melt adhesive commonly used in clothing. This hot melt adhesive can melt at around 110°C and is solid at room temperature.
[0037] Combination Figure 4 As shown, the second aspect of this embodiment provides a garment comprising the core-spun yarn described in the first aspect. The garment in this embodiment comprises the aforementioned core-spun yarn, whose fixed active particles enable the garment to possess certain functions such as temperature and humidity regulation, improving the comfort of the garment. Furthermore, the active particles do not directly contact the skin, and the outer layer also provides protection, achieving efficient utilization and long-lasting fixation of the active particles, thus ensuring the garment's temperature and humidity regulation functions are durable.
[0038] Based on the above embodiments, as an optional implementation, the garment includes a composite yarn, which is made by twisting core-spun yarn and synthetic fibers together to form strands, and the garment is woven using the composite yarn. In this embodiment, by twisting core-spun yarn and synthetic fibers together to form a composite yarn, the elasticity of the garment is improved, making it more suitable for everyday wear and extending its service life. The synthetic fiber includes nylon, which has the characteristics of being abrasion-resistant, lightweight, and elastic.
[0039] Based on the above embodiments, as an optional implementation, the distance between the functional layer 20 in the garment and the skin is 0.1 mm to 0.3 mm. This allows the distance between the functional layer 20 and the skin to be within an optimal range, improving the utilization rate of the active particles and the comfort of skin contact. It avoids the discomfort caused by close contact between the active particles in the functional layer 20 and the skin, as well as the low utilization rate and reduced regulatory effect of the active particles caused by a large distance between them and the skin.
[0040] Based on the above embodiments, as an optional implementation method, combined with Figure 4 As shown, where Figure 4 A represents the front of the garment. Figure 4 B represents the back of the garment. The garment comprises a bodice 1, a collar 2, and sleeves 3 sewn together. The bodice 1 is formed by sewing together a front and back piece. Two sleeves 3 are attached to the sides of the bodice 1, and the collar 2 is attached to the top of the bodice 1. The bodice 1, collar 2, and sleeves 3 are all knitted from composite yarns. This garment can be a sweater. Garments knitted from composite yarns not only have certain temperature and humidity regulation functions, improving comfort, but also have good elasticity and abrasion resistance. As an optional implementation, the bodice 1, collar 2, and sleeves 3 are all knitted from composite yarns using a four-stitch knitting method. Figure 5 As shown, it illustrates a schematic diagram of the structure of a four-line stitch 4 woven using the four-line stitch knitting method.
[0041] Based on the above embodiments, as an optional implementation, the sleeves 3 of the garment have elastically tightened cuffs 31, the collar 2 is an elastically tightened collar, and the lower end of the garment body 1 has an elastically tightened hem 11. Therefore, by providing elastically tightened cuffs, an elastically tightened collar, and an elastically tightened hem, the elasticity of the cuffs, collar, and hem is improved, allowing the garment to better fit and wrap around the body, providing windproof and warmth retention, and enhancing the garment's warmth-keeping effect.
[0042] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
