Description

Technical Field

[0001] This utility model relates to the technical field of hollow polyester filament, and in particular to a multi-microporous hollow polyester POY filament. Background Technology

[0002] Polyester filament is a long filament made of polyester that is over a kilometer in length. Polyester is an important type of synthetic fiber. It is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions, and then spun and post-processed into fibers.

[0003] Most existing polyester filaments, after being made into clothing and other products, suffer from insufficient breathability due to their inherent structural characteristics, resulting in a poor wearing experience. Furthermore, after being processed to become elastic, due to their high toughness, they can only be stretched to a small length when stretched, and their elasticity is not outstanding. Moreover, the breathability of the fabric is further reduced when the existing polyester filaments are woven into cloth. In order to solve these problems, a multi-microporous hollow polyester POY filament is proposed. Utility Model Content

[0004] This invention provides a multi-microporous hollow polyester POY filament, which solves the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A multi-microporous hollow polyester POY filament includes a polyester protective jacket and an elastic composite filament installed inside the polyester protective jacket; the elastic composite filament includes high-elastic fiber filaments, hollow fiber filaments are arranged on the outer side of the high-elastic fiber filaments, and elastic polyester filaments are arranged on the outer side of the hollow fiber filaments; micropores are formed on the surface of both the hollow fiber filaments and the polyester protective jacket.

[0007] Preferably, the hollow fiber filaments and elastic polyester yarns are both spirally mounted on the outside of the high-elastic fiber filaments, and the hollow fiber filaments and elastic polyester yarns are interlaced and wound around the high-elastic fiber filaments.

[0008] Preferably, the surfaces of both the elastic polyester yarn and the polyester protective jacket are configured in a spiral shape.

[0009] Preferably, the high-elastic fiber filament comprises flexible fibers, the flexible fibers are shaped as spring-like curls, and the flexible fibers are spirally wound together to form a high-elastic fiber filament.

[0010] Preferably, the polyester protective jacket is fitted over the outside of the hollow fiber filaments and elastic polyester yarn.

[0011] Preferably, the micropores are arranged in a matrix.

[0012] The advantages and positive effects of this utility model are as follows: By using a polyester protective jacket and elastic composite yarn, the elasticity of the polyester yarn is enhanced by the high-elasticity fiber filaments and hollow fiber filaments of the elastic composite yarn. When under stress, the elasticity of the high-elasticity fiber filament itself, together with the spirally installed hollow fiber filaments and elastic polyester yarn, can enhance the elasticity, thereby enhancing the tensile elasticity of the polyester yarn. Furthermore, through the polyester protective jacket and micropores, micropores are opened on the surface of both the hollow fiber filaments and the surface of the polyester protective jacket during use, which facilitates the polyester protective jacket and hollow fiber filaments to enhance ventilation through the micropores, thereby enhancing the breathability after the fabric is woven.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0021] Reference Figure 1 and Figure 2 as well as Figure 3As shown, polyester filament is a long filament made of polyester with a length of over one kilometer. Polyester is an important type of synthetic fiber. It is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions, and then spun and post-processed into fibers. Currently, most polyester filaments, after being made into clothing and other products, suffer from insufficient breathability due to their inherent structural characteristics, resulting in a poor wearing experience. Furthermore, after processing to achieve elasticity, due to its high toughness, it can only be stretched to a relatively small length, resulting in relatively poor elasticity. Moreover, the breathability of fabrics woven from existing polyester filaments is further reduced during use. To address these issues, a multi-microporous hollow polyester POY filament is proposed, comprising a polyester protective jacket 1 and an elastic composite yarn 2 installed inside the polyester protective jacket 1; the elastic composite yarn 2 includes... The fabric includes a high-elastic fiber filament 3, with hollow fiber filaments 4 on the outer side of the high-elastic fiber filament 3, and elastic polyester yarn 5 on the outer side of the hollow fiber filament 4. Both the hollow fiber filament 4 and the polyester protective jacket 1 have micropores 6 on their surfaces. Through the polyester protective jacket and the elastic composite yarn, the high-elastic fiber filaments and hollow fiber filaments of the elastic composite yarn enhance the elasticity of the polyester filament during use. Under stress, the elasticity of the high-elastic fiber filament itself, combined with the spirally arranged hollow fiber filaments and elastic polyester yarn, can enhance the elasticity, thereby strengthening the tensile elasticity of the polyester filament. Furthermore, through the polyester protective jacket and the micropores, the micropores on the surfaces of both the hollow fiber filaments and the polyester protective jacket facilitate ventilation, thus enhancing the breathability of the fabric after weaving.

[0022] It should be noted that the surfaces of both the elastic polyester yarn 5 and the polyester protective jacket 1 are designed in a spiral shape. After treatment with ammonia and twisting the polyester, the ammonia will change the molecular structure of the polyester, increasing the elasticity of the fiber. Twisting will make the surface of the polyester fiber form a spiral shape, increasing its tensile elasticity and strengthening the elasticity of the elastic polyester yarn 5 and the polyester protective jacket 1.

[0023] Furthermore, the polyester protective jacket 1 is fitted over the hollow fiber filament 4 and the elastic polyester thread 5, making it convenient to use the polyester filaments in strips.

[0024] Furthermore, the hollow structure of the hollow fiber filament 4 and the micropores 6 on the surface of the polyester protective jacket 1 enhance the breathability of the fabric during use; the high-elastic fiber filament 3 includes flexible fibers 7, the shape of which is made into a spring-like curl by false twisting, and the flexible fibers 7 are spirally wound together to form the high-elastic fiber filament 3, which is used in the high-elastic fiber filament 3 itself.

[0025] It should also be noted that micropores 6 are provided on the surface of both the hollow fiber filament 4 and the polyester protective jacket 1 during use. This allows the polyester protective jacket 1 and the hollow fiber filament 4 to have better ventilation through the micropores 6, thereby enhancing the breathability of the fabric after it is woven.

[0026] Additionally, during use, the flexible fibers 7 are coiled in a spring-like shape and intertwined to form high-elastic fiber filaments 3. Then, hollow fiber filaments 4 and elastic polyester threads 5 are sequentially wound around the outside of the high-elastic fiber filaments 3. Finally, the polyester protective jacket 1 is placed over the hollow fiber filaments 4 and elastic polyester threads 5. During use, the hollow fiber filaments 4 and high-elastic fiber filaments 3 enhance elasticity, and the spiral shape of the hollow fiber filaments 4 and elastic polyester threads 5 allows them to stretch to a longer length under stress, thereby enhancing the overall elasticity of the polyester filaments. After being woven into fabric, the hollow structure of the hollow fiber filaments 4 and the micropores 6 on the surface of the polyester protective jacket 1 enhance the breathability of the fabric during use.

[0027] Furthermore, the micropores 6 are arranged in a matrix pattern. This matrix arrangement ensures that the entire polyester filament exhibits a multi-micropore distribution, resulting in better ventilation and better suiting the setup of multi-micropore hollow polyester POY filaments.

[0028] It is worth mentioning that the POY in the aforementioned polyester POY filament does not have any limiting meaning in this case; it simply indicates that it is a method of high-speed spinning.

[0029] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
