Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to a thermal polyester fabric. Background Technology

[0002] Polyester fabric is a type of fabric woven from polyester fibers. Polyester fibers are a synthetic fiber with a dense molecular structure that makes it difficult for air to penetrate, effectively blocking the flow of air. As a result, polyester fabrics have excellent windproof properties and are often used in the production of windproof jackets and warm clothing.

[0003] To improve warmth, the weave density and thickness of the fabric are usually increased, or a windproof coating is added, making the finished garments thicker and bulkier, restricting movement. At the same time, the tight molecular structure of polyester fibers reduces the gaps and surface area within the fibers, resulting in poor moisture wicking properties in the polyester fabric. Therefore, when the wearer sweats, the sweat produced cannot be quickly wicked away through the fabric and remains on the skin, thus affecting the comfort of wearing the garment.

[0004] Therefore, a new fabric needs to be designed that can reduce weight and thickness while ensuring good warmth retention and good moisture wicking properties. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warm polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a warm polyester fabric, comprising an inner layer and an outer layer, wherein a plurality of moisture-wicking blocks are arranged in an array on the side of the outer layer near the inner layer, the cross-sectional shape of the moisture-wicking blocks is cross-shaped, the inner layer and the outer layer are supported by the plurality of moisture-wicking blocks to form a heat insulation cavity, a plurality of heat insulation grooves are woven in an array on the side of the inner layer away from the outer layer, and a plurality of moisture-dissipating blocks are arranged in an array on the side of the outer layer away from the inner layer, the cross-sectional shape of the moisture-dissipating blocks is H-shaped, and the moisture absorption of the moisture-wicking blocks and the moisture-dissipating blocks is greater than that of the inner layer and the outer layer.

[0007] The present invention is further configured such that a plurality of the moisture-guiding blocks and moisture-dispersing blocks are staggered along the radial direction of the outer layer, and the moisture-guiding blocks and moisture-dispersing blocks have the same thickness.

[0008] The present invention is further configured such that: the outer layer's weaving structure is a warp-patterned weave, and the yarn used to weave the outer layer includes windproof yarn and moisture-wicking yarn, wherein the windproof yarn serves as the ground weave yarn of the warp-patterned weave, and the moisture-wicking yarn serves as the pattern yarn of the warp-patterned weave.

[0009] The present invention is further configured such that: the windproof yarn is made of twisted polyester fibers, the diameter of the windproof yarn is set to 0.1-0.3mm, and the weaving density of the outer layer is set to 183*175 / cm².

[0010] The present invention is further configured such that: the moisture-wicking yarn is made of twisted hemp fibers, and the moisture-wicking block and the moisture-wicking block are both formed by patterned yarn with a patterned structure.

[0011] The present invention is further configured such that: the inner layer and the plurality of heat insulation grooves thereon are integrally formed by a honeycomb weaving method, and the yarn used to weave the inner layer is a moisture-absorbing yarn, which is made of polyester profiled fibers twisted together.

[0012] In summary, this invention has the following beneficial effects: The presence of air between the skin and the inner layer is increased through several heat-insulating grooves, and air between the inner and outer layers is increased through the heat-insulating cavity. Since air is a poor conductor of heat, an air-insulating layer can be formed between the skin and the inner layer, and between the inner and outer layers, effectively limiting temperature transfer across the fabric and achieving good warmth retention. Simultaneously, the heat-insulating cavity and several heat-insulating grooves reduce the overall weight of the fabric while maintaining warmth. The outer layer, made of finer polyester with a higher weave density, has good windproof properties while reducing its thickness. The improved moisture absorption of the polyester fibers through special-shaped shaping gives the inner layer a certain degree of moisture absorption and reduces its weight. Linen fibers have strong moisture absorption and rapid moisture dissipation characteristics, allowing the moisture absorbed in the inner layer to be transferred through several moisture-wicking blocks to several moisture-dissipating blocks and to quickly dissipate moisture through full contact with external airflow, thus ensuring the dryness of the inner layer and skin and making the finished garment comfortable to wear.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: Warm polyester fabric, such as Figures 1-4 As shown, the fabric includes an inner layer 1 and an outer layer 2. Both inner and outer layers 1 and 2 are thin and lightweight, resulting in a lightweight fabric. Several moisture-wicking blocks 3 are arranged in an array on the side of the outer layer 2 closest to the inner layer 1. The moisture-wicking blocks 3 have a cross-shaped cross-section. Supported by these moisture-wicking blocks 3, the inner and outer layers 1 and 2 form a grid-like heat-insulating cavity 4, increasing the air content between the inner and outer layers 1 and 2. Since air is a poor conductor of heat, the heat-insulating cavity 4 forms an air insulation layer between the inner and outer layers 1 and 2, thereby reducing temperature transfer between them. The inner layer 1, on the side away from the outer layer 2, is woven with a plurality of arrayed heat-insulating grooves 5. The heat-insulating grooves 5 increase the air content between the inner layer 1 and the skin. At the same time, the air between the skin and the heat-insulating grooves 5 is restricted by the inner layer 1 and does not circulate with the outside. As a poor conductor of heat, air can effectively reduce the transfer of temperature, so that the heat-insulating cavity 4 can form an air heat-insulating layer between the inner layer 1 and the outer layer 2, thereby reducing the temperature transfer between the skin and the inner layer 1. This makes the fabric effectively reduce the loss of body surface temperature and improve the warmth retention effect without increasing the weight of the fabric.

[0021] like Figures 1-5 As shown, several moisture-wicking blocks 6 are arranged in an array on the side of the outer layer 2 away from the inner layer 1. The cross-sectional shape of the moisture-wicking blocks 6 is H-shaped. The thickness of the moisture-wicking blocks 3 and the moisture-wicking blocks 6 is the same. The weaving structure of the outer layer 2 is set as a warp-raised pattern. The yarn used to weave the outer layer 2 includes windproof yarn and moisture-wicking yarn. The windproof yarn is fed into the multi-arm loom as the ground weave yarn of the warp-raised pattern and woven in a plain weave pattern to form the outer layer 2. The moisture-wicking yarn is fed into the multi-arm loom along the warp direction as the starting yarn of the warp-raised pattern. Several moisture-wicking blocks 3 and moisture-wicking blocks 6 are arranged alternately along the warp direction of the outer layer 2. Several moisture-wicking blocks 6 are formed by several starting yarns arranged side by side floating on the side of the ground weave away from the inner layer. Several moisture-wicking blocks 3 are formed by several starting yarns arranged side by side floating on the side of the ground weave close to the inner layer.

[0022] like Figures 2-4As shown, the windproof yarn is made by twisting polyester fibers using a twisting machine. The diameter of the windproof yarn is set to 0.1-0.3mm, and the weaving density of the outer layer 2 is set to 183*175 / cm². Due to its compact molecular structure, polyester fiber has good elasticity, abrasion resistance, and windproof properties. The outer layer 2, made of finer windproof yarn with a higher weaving density, is relatively compact, resulting in higher strength and better windproof performance, while reducing the thickness of the outer layer 2. The inner layer 1 and its several heat insulation grooves 5 are all made by... The moisture-absorbing yarn is fed into the multi-arm loom and formed integrally by a honeycomb weaving method. The yarn used to weave the inner layer 1 is set as a moisture-absorbing yarn. The moisture-absorbing yarn is made by twisting polyester profiled fibers. By profiled polyester fibers, the porosity and surface area within the fibers are increased, which is conducive to the penetration and diffusion of moisture, thereby improving the moisture absorption. Moreover, the profiled polyester fibers reduce weight while increasing porosity. As a result, the inner layer 1 made of polyester profiled fibers reduces weight while ensuring moisture absorption, making the fabric lightweight and thin overall.

[0023] like Figure 3 and Figure 4 As shown, the moisture-wicking yarn is made by twisting hemp fibers through a twisting machine. Due to its special porous structure, hemp fibers have stronger moisture absorption and faster moisture dissipation characteristics than polyester fibers and polyester profiled fibers. As a result, the moisture absorption of the moisture-wicking blocks 3 and moisture-wicking blocks 6 formed by the moisture-wicking yarn is greater than that of the inner layer 1 and the outer layer 2. Therefore, the moisture absorbed in the inner layer 1 can be transferred to the moisture-wicking blocks 6 in a timely manner through the moisture-wicking blocks 3 and make full contact with the airflow of the outside to quickly dissipate moisture, thereby maintaining the dryness between the inner layer 1 and the skin, so that the clothing made from this fabric has a comfortable wearing feel.
