A double-sided mesh fabric with one-way moisture guiding function

Abstract

This utility model discloses a double-sided mesh fabric with unidirectional moisture-wicking function. From the outside to the inside, it includes a mesh fabric outer layer and a mesh fabric inner layer, which are connected together. The mesh fabric is formed by an upper needle plate and a lower needle cylinder. The upper needle plate operates in two-segment cycles, and the lower needle cylinder operates in four-segment cycles. The feature of this utility model is the use of unique yarns and weaving techniques. The inner layer uses hydrophobic polyester yarn, while the outer layer uses high-count hydrophilic modified polyester yarn. This creates a water absorption gradient between the two layers, allowing moisture or sweat to be transferred from the inner layer to the outer layer, thus providing unidirectional moisture-wicking properties. This fabric is soft and skin-friendly, smooth and comfortable to the touch, with a delicate texture. It is non-irritating to the skin, comfortable to wear, and meets consumers' needs for quick-drying and unidirectional moisture-wicking functions in spring and summer sportswear.

Description

Technical Field

[0001] This utility model relates to the field of double-sided mesh fabric technology, and in particular to a double-sided mesh fabric with unidirectional moisture-wicking function. Background Technology

[0002] With the widespread application of multifunctional textile fabrics, people's demands for textiles have long since evolved from simply providing aesthetic appeal and protection from wind and rain to offering a wider range of functionalities. In daily life, consumers often find polyester unacceptable due to its stuffiness and lack of breathability, as polyester is inherently a water-repellent fiber and generally lacks moisture absorption. It traps sweat inside the clothing, preventing body heat from escaping and causing discomfort. Therefore, consumers prefer pure cotton clothing because it absorbs moisture. However, pure cotton clothing is not perfect either; while absorbent, it dries slowly and clings to the skin. If there were a layer separating the skin from the clothing, preventing sweat from contacting the skin, this discomfort would be eliminated. The emergence of one-way moisture-wicking fabrics effectively solves these problems. When the body sweats, the sweat is carried away from the inner layer to the outer layer by the one-way moisture-wicking fabric, keeping the inner layer dry. It's like a membrane separating the skin and sweat, preventing direct contact and ensuring dryness. One-way moisture-wicking fabrics are becoming the trend, so it is of great significance to study a mesh fabric with one-way moisture-wicking function. Utility Model Content

[0003] The purpose of this invention is to solve the above problems by designing a double-sided mesh fabric with one-way moisture-wicking function. The outer layer and the inner layer of the mesh fabric are connected together. The mesh fabric is formed by an upper needle plate and a lower needle cylinder. The upper needle plate has two segments as one cycle, and the lower needle cylinder has four segments as one cycle. Eight lines form a complete structure. The arrangement of the eight lines consists of three weaving structures: float weave, loop weave, and tuck weave.

[0004] The technical solution of this utility model to achieve the above objectives is a double-sided mesh fabric with unidirectional moisture-wicking function, characterized in that: [The eight channels are described in the original text, but the provided text is incomplete and requires further context.]

[0005] The first row consists of, in order: looped structure, looped structure, floating structure, clustered structure, floating structure, and floating structure;

[0006] The second row consists of, in sequence, floating line structure, floating line structure, loop structure, loop structure, loop structure, and loop structure;

[0007] The third line consists of looped weave, looped weave, float weave, float weave, float weave, and float weave.

[0008] The fourth row consists of, in sequence, floating line structure, floating line structure, loop structure, loop structure, loop structure;

[0009] The fifth line consists of, in order: looped structure, looped structure, floating structure, floating structure, floating structure, and clustered structure;

[0010] The sixth row consists of, in sequence, floating line structure, floating line structure, loop structure, loop structure, loop structure, and loop structure;

[0011] The seventh line consists of, in sequence, looped weave, looped weave, float weave, float weave, float weave;

[0012] The eighth row consists of, in sequence, floating line structure, floating line structure, loop structure, loop structure, loop structure, and loop structure.

[0013] As a further explanation of this utility model, the inner layer of the mesh fabric has polyester water-repellent yarn threaded into the second, fourth, sixth, and eighth threads of the 72-row weave. The outer layer of the mesh fabric has high-count hydrophilic modified polyester yarn threaded into the first, third, fifth, and seventh threads of the 72-row weave.

[0014] 8F is a small loop, forming a small mesh. A total of nine small loops form a large loop, for a total of seventy-two paths.

[0015] The yarn used in the high-count hydrophilic modified polyester yarn has a yarn specification of 8.33tex / 72f (75D / 72F);

[0016] The polyester water-repellent yarn is made of 5.56 tex / 24F (50D / 24F) polyester filament.

[0017] Two types of yarn are interwoven to form a double-sided mesh fabric with one-way moisture-wicking function.

[0018] The beneficial effects lie in the fact that the double-sided mesh fabric produced by this invention uses 5.56tex / 24F (50D / 24F) polyester water-repellent yarn. The principle behind this technology, where the polyester filaments of the water-repellent yarn can be made into a unidirectional moisture-wicking fabric, is achieved by adding a water-repellent agent during the spinning process. This alters the chemical properties of the polyester, increasing its hydrophobicity and transforming the hydrophilicity of the fiber surface into hydrophobicity. By using a hydrophobic polyester water-repellent yarn in the inner layer and a hydrophilic high-count hydrophilic modified polyester yarn in the outer layer, a water absorption gradient is created between the two layers. This allows moisture or sweat to rapidly transfer from the inner layer (the side in contact with the skin) to the outer layer (the side away from the skin), where it evaporates and diffuses. This enables moisture to be rapidly conducted along a specific direction on the fabric, thus achieving highly efficient moisture absorption and wicking.

[0019] This invention employs a unique weaving process and novel design in the preparation of mesh fabric, making it suitable for market production and application.

[0020] The double-sided mesh fabric with unidirectional moisture-wicking function obtained by this invention is soft and comfortable, absorbs and wicks away moisture, and has good unidirectional transfer index performance. It is widely used in sports and leisure clothing and other fields. Attached Figure Description

[0043]

[0044] 2. Bursting strength and color fastness:

[0047]

[0048] 3. Moisture-wicking and quick-drying properties:

[0049] The test results of the fabric's moisture absorption and quick-drying properties are shown in Table 5;

[0050] Table 5. Results of moisture absorption and quick-drying performance tests

[0051]

[0052] As shown in Tables 3-5, the unidirectional moisture-wicking mesh fabric developed in this paper exhibits good basic performance, with excellent wash and abrasion resistance, and color fastness to perspiration reaching levels 4-5 or higher. Warp and weft shrinkage rates are both within 5%, meeting the required standard values ​​for the fabric. In terms of functionality, all test results also meet the standard requirements. Snag resistance reaches level 3-4, bursting strength and various color fastness values ​​meet national standards, and the fabric demonstrates excellent moisture absorption and quick-drying properties. The fabric's wicking height is 190 mm, water absorption rate is 430%, drip diffusion time is 0.9 s, evaporation rate is 0.3 g / h, and the unidirectional transfer index is level 5, far exceeding the national standard value. This allows moisture or sweat to rapidly transfer from the inner layer (the side in contact with the skin) to the outer layer (the side away from the skin) and evaporate and diffuse there. It enables rapid moisture conduction along a specific direction on the fabric, thus achieving highly efficient moisture absorption and wicking functions.

[0053] In summary, the unidirectional moisture-wicking mesh fabric produced by this invention is a textile fabric with special functions. This type of fabric does not stick to the skin, is very comfortable to wear, and is the first choice for sports fabrics. It is widely used in sportswear, functional underwear, outdoor equipment, etc.
