Description

TECHNICAL FIELD

[0001] The utility model relates to a blended yarn technical field, concretely relates to a modified polyester fiber blended yarn. BACKGROUND

[0002] Polyester fiber (polyester) is commonly known as "polyester", which is a kind of synthetic fiber made of organic diacid and dihydric alcohol through chemical polycondensation, and it belongs to a kind of high molecular compound. Polyester fiber has excellent wrinkle resistance and shape retention, and the clothes made of polyester fiber are not easy to wrinkle during wearing, which can maintain the original shape of the clothes. In addition, polyester fiber also has the characteristics of anti-wear and no hair sticking, which makes the fabric look more neat. However, the disadvantages of polyester fiber are also obvious, and it has obvious shortcomings in softness, air permeability and warmth retention, especially in cold seasons or special environments, the lack of these performances affects the wearing experience. Polyester fiber itself does not have the function of moisture absorption and perspiration, which is easy to cause stuffy feeling, especially when wearing for a long time, the discomfort is particularly obvious. Therefore, the clothes made of traditional polyester fiber often give people the impression of "not breathable" and "uncomfortable", which cannot provide ideal wearing experience.

[0003] Blending refers to the mixing of two or more different types of fibers for spinning and weaving, to obtain blended fabric, the raw materials for blending include chemical fibers and natural fibers. The advantages of blended fabric are that through the organic combination of two or more different types of fibers, the advantages are complementary, and the advantages are complementary, which can meet the different requirements of people for clothing. It has practical significance to improve the polyester fiber raw material through blending and obtain a textile yarn that can absorb moisture, perspiration, softness, warmth retention and antibacterial properties. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a kind of modified polyester fiber blended yarn, solve the problem of function deficiency of polyester fiber yarn used alone, cannot meet market needs.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A kind of modified polyester fiber blended yarn, including yarn core, elastic warmth layer and antibacterial stain-proof layer;The elastic warmth layer is that modified polyester fiber is set by being wrapped around the outside of yarn core as center by twisting mode;The antibacterial stain-proof layer is that artificial fiber is set by being wrapped around the outside of elastic warmth layer as center;

[0007] The modified polyester fiber is dumbbell-shaped polyester fiber.

[0008] This preferred solution employs a process of blending modified polyester fibers to produce yarn. The resulting yarn consists of three parts from the inside out: a yarn core, an elastic thermal insulation layer, and an antibacterial and stain-resistant layer. Through the blending process, the inherent characteristics of the raw materials are further explored, combining the three parts to achieve a synergistic effect.

[0009] In this invention, polyester fiber is used in the elastic thermal insulation layer. Polyester fiber, also known as polyester, has advantages such as high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, and excellent light resistance. However, its disadvantages include poor moisture absorption, difficulty in dyeing, and relatively low elasticity. Therefore, its application has traditionally been limited. Through physical processing techniques, modified polyester fibers are obtained, exhibiting a dumbbell-shaped cross-section. This geometric change increases the elasticity of the polyester fibers and also increases the gaps between the fibers, providing more air layers and enhancing air retention capacity, thus significantly improving the fabric's thermal insulation effect.

[0010] Furthermore, the raw material for the yarn core is natural fiber.

[0011] Furthermore, the natural fiber mentioned is cotton fiber.

[0012] This preferred embodiment uses cotton fiber as the raw material for the yarn core. Cotton fiber has good heat retention and moisture absorption, but its ability to wick away moisture is poor, making people feel damp easily after sweating. This invention uses a yarn core as the center, wrapping modified polyester fiber around it to form an elastic insulating layer. Because the modified polyester fiber used has a dumbbell-shaped structure, there are many gaps in the connecting structure between two dumbbell-like plates. When it is spirally wrapped around the cotton fiber, it forms spaced microchannels. These channels can conduct moisture from inside the cotton fiber to the outside, overcoming the problem of poor moisture wicking in pure cotton structures.

[0013] Furthermore, the synthetic fiber is acrylic fiber, and the acrylic fiber contains added silver nanoparticles.

[0014] This preferred design uses acrylic fiber as the raw material for the antibacterial and stain-resistant layer. Acrylic fiber has good resistance to sunlight and weathering, and poor moisture absorption. By wrapping it around the elastic insulation layer with the yarn core as the center, an antibacterial and stain-resistant layer is formed. Its good durability extends its service life; its poor moisture absorption prevents external rainwater or other liquids from entering, and allows liquids transported from the yarn core through the elastic insulation layer to be quickly transported to the outside of the yarn, preventing internal accumulation. Both aspects work together to achieve water-resistant and moisture-wicking functions. Furthermore, by adding nano-silver particles to the surface of the acrylic fiber, a bactericidal effect is achieved. Combined with the overall water-resistant and moisture-wicking properties, this not only reduces the entry of external contaminants but also reduces bacterial growth by minimizing internal droplet accumulation.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] (1) This utility model employs a process of blending modified polyester fibers to produce yarn. The produced yarn consists of three parts from the inside out: a yarn core, an elastic insulating layer, and an antibacterial and stain-resistant layer. Through the blending process, the inherent characteristics of the raw materials are further explored, and the three parts of the raw materials are combined to achieve the effect of complementing each other's strengths and weaknesses. In the elastic insulating layer, this invention uses polyester fiber. Polyester fiber, also known as polyester, has the advantages of high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, and good light resistance. However, its disadvantages are poor moisture absorption, difficulty in dyeing, and low elasticity. Therefore, its application range has been traditionally limited. Through physical processing technology, the modified polyester fiber obtained has a dumbbell-shaped cross-section. This change in geometric shape increases the elasticity of the polyester fiber on the one hand, and increases the gaps between the fibers on the other hand, providing more air layers, enhancing air retention capacity, and significantly improving the warmth retention effect of the fabric.

[0017] (2) This invention uses cotton fiber as the raw material for the yarn core. Cotton fiber has good heat retention and moisture absorption, but poor moisture wicking after absorbing moisture, making people feel damp easily after sweating. This invention uses the yarn core as the center and wraps modified polyester fiber around it to form an elastic heat-insulating layer. Because the modified polyester fiber used has a dumbbell-shaped structure, there are a lot of gaps in the connecting structure between two dumbbell-like plates. When it is spirally wrapped around the outside of the cotton fiber, it forms a series of small channels that can conduct moisture inside the cotton fiber to the outside, overcoming the problem of poor moisture wicking after absorbing moisture in the pure cotton structure.

[0018] (3) This invention uses acrylic fiber as the raw material for the antibacterial and antifouling layer. Acrylic fiber has good resistance to sunlight and weathering, and poor moisture absorption. It is wrapped around the elastic insulation layer with the yarn core as the center to form the antibacterial and antifouling layer. Its good durability extends its service life; its poor moisture absorption prevents external rainwater or other liquids from entering, and allows liquids transported from the yarn core through the elastic insulation layer to be quickly transported to the outside of the yarn, preventing internal accumulation. Both aspects work together to achieve water-resistant and moisture-wicking functions. Furthermore, adding nano-silver particles to the surface of the acrylic fiber has a bactericidal effect. Combined with the overall water-resistant and moisture-wicking properties, it not only reduces the entry of external pollutants but also reduces bacterial growth by minimizing internal droplet accumulation. This invention solves the problem that using polyester fiber yarn alone is insufficient in function and cannot meet market needs. Attached Figure Description
