[0028] In actual use of an existing antistatic polyester stretch yarn, the rubber yarn as the material of the yarn core can increase the elasticity of the stretch yarn body, but the rubber yarn may take a long time to return to its original state after being stretched, or it may not be able to fully return to its original state, which may cause the fabric to gradually lose its elasticity during use and affect the appearance. Therefore, a polyester stretch yarn with better elasticity and durability is provided.
[0029] Embodiment 1:
[0030] like Figures 1 to 4 The utility model provides a high-elastic polyester stretch yarn.
[0031] Specifically, by Figure 1-Figure 3A high-elastic polyester stretch yarn is provided, comprising a polyester stretch yarn as a whole 1, a central polyester layer 2 is arranged inside the polyester stretch yarn as a whole 1, an elastic layer 7 is fixedly connected to the outer wall of the central polyester layer 2, the inner wall of the elastic layer 7 is fitted with the outer wall of the central polyester layer 2, the outer wall of the elastic layer 7 is connected to an elastic layer 6, the inner wall of the elastic layer 6 is fitted with the inner wall of the elastic layer 7, the elastic layer 6 and the elastic layer 7 are both located inside the polyester stretch yarn as a whole 1, the elastic layer 6 is made of spandex material, and the elastic layer 7 is made of polypropylene material.
[0032] The central polyester layer 2 is the core part of the polyester stretch yarn 1, and is mainly responsible for providing overall strength and stability. The elastic layer 7 is made of polypropylene, which has excellent elasticity and recovery, and can effectively increase the elasticity and resilience of the polyester stretch yarn 1. Polypropylene also has good heat resistance and chemical corrosion resistance, which can improve the stability and durability of the overall structure. The spandex used in the elastic layer 6 also has excellent elastic properties, can be stretched to several times its original length, and quickly return to its original shape after releasing external force. This high elasticity makes spandex the best option for making stretch fabrics. Both the elastic layer 6 and the elastic layer 7 have excellent elastic properties, can be stretched to a greater extent and quickly return to their original shape, and have excellent elastic properties, can be stretched to a greater extent and quickly return to their original shape.
[0033] Further:
[0034] like Figure 2-Figure 3 It is shown that the outer wall of the elastic layer 6 is connected with a plurality of tensile layers 5 , the outer wall of the tensile layer 5 is in contact with the outer wall of the elastic layer 6 , and the material of the tensile layer 5 is polyamide elastomer.
[0035] Using polyamide elastomer as the material of the tensile layer 5 can effectively improve the tensile strength and elasticity of the entire structure. When external force acts on the structure, the tensile layer 5 can disperse and bear part of the tensile force, reduce the burden on the elastic layer 6 and the elastic layer 7, and prevent them from being overstretched or torn. At the same time, the resilience of the tensile layer 5 made of polyamide elastomer can also ensure that the polyester elastic yarn as a whole 1 can quickly return to its original state after being subjected to force, thereby maintaining the stability and durability of the structure.
[0036] Further:
[0037] like Figure 2-Figure 4 It is shown that the outer layer 4 is connected between the multiple tensile layers 5 , the inner wall of the outer layer 4 is connected to the outer walls of the multiple tensile layers 5 , and the tensile layer 5 is located between the outer layer 4 and the elastic layer 6 .
[0038] The outer layer 4 is located at the outermost periphery of the polyester elastic yarn 1 and is used to protect the tensile layer 5 . At the same time, the outer layer 4 cooperates with the elastic layer 6 to make the connection between the multiple tensile layers 5 tighter, thereby improving the stability of the tensile layer 5 .
[0039] Further:
[0040] like Figure 2-Figure 3 It is shown that the outer walls of the elastic layer 6 and the elastic layer 7 are sprayed with coloring agent.
[0041] When the elastic layer 6 of spandex material and the elastic layer 7 of polypropylene material are exposed to the sun, ultraviolet rays will damage them, causing aging, discoloration and even degradation of the materials. The pigments or dyes in the colorant can reflect ultraviolet rays and reduce the chance of ultraviolet rays directly penetrating the materials. This reflection effect can reduce ultraviolet damage to the materials, thereby reducing aging, discoloration and degradation.
[0042] Further:
[0043] like Figure 2-Figure 3 It is given that the material of the outer layer 4 is polypropylene, and the outer layer 4 is coated with an antioxidant.
[0044] The outer layer 4 of polypropylene material can protect the material inside the polyester stretch yarn 1 from erosion and damage by the external environment, such as ultraviolet rays, moisture, chemicals, etc., thereby extending the service life of the polyester stretch yarn 1. The antioxidant helps to maintain the mechanical properties, chemical stability and appearance of the polypropylene inner wall, thereby extending its service life.
[0045] Embodiment 2:
[0046] Further:
[0047] like Figure 1-Figure 2 It is shown that a high-elastic adhesive 3 is connected between the plurality of tensile layers 5 .
[0048] The function of the high-elastic adhesive 3 is to form a strong bond between the multiple tensile layers 5 to ensure that the layers work together and jointly withstand the external tensile stress. This adhesive usually has excellent elasticity, water resistance and aging resistance to ensure that the tensile layer 5 maintains a stable bonding effect during long-term use and effectively avoids the dispersion of multiple tensile layers 5.
[0049] Working principle:
[0050] The central polyester layer 2 is the core part of the polyester stretch yarn 1, and is mainly responsible for providing overall strength and stability. The elastic layer 7 is made of polypropylene, which has excellent elasticity and recovery, and can effectively increase the elasticity and resilience of the polyester stretch yarn 1. Polypropylene also has good heat resistance and chemical corrosion resistance, which can improve the stability and durability of the overall structure. The spandex used in the elastic layer 6 also has excellent elastic properties, can be stretched to several times its original length, and quickly return to its original shape after releasing external force. This high elasticity makes spandex the best option for making stretch fabrics. Both the elastic layer 6 and the elastic layer 7 have excellent elastic properties, can be stretched to a greater extent and quickly return to their original shape, and have excellent elastic properties, can be stretched to a greater extent and quickly return to their original shape.
[0051] The function of the high-elastic adhesive 3 is to form a strong bond between the multiple tensile layers 5 to ensure that the layers work together and jointly withstand the external tensile stress. This adhesive usually has excellent elasticity, water resistance and aging resistance to ensure that the tensile layer 5 maintains a stable bonding effect during long-term use and effectively avoids the dispersion of multiple tensile layers 5.
[0052] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
