Description

Sports lace fabric with adjustable water conduction in the thickness direction of the fabric

Technical Field

The invention belongs to the technical field of textile fabrics, in particular to a sports lace fabric with adjustable water conduction in the thickness direction of the fabric.

Background Art

In recent years, with the development of science and technology, people's quality of life has been continuously improved, and the requirements for clothing have also been increasing. In addition to its basic function of aesthetics, it is also necessary to meet various functions in different environments or occasions. To this end, technicians have carried out a lot of research on the expansion and improvement of the functionality of textile fabrics. Among the many research directions, unidirectional moisture-conducting textiles have become one of the research hotspots because they fit the sports, health, and active lifestyles advocated by people in recent years. This functional fabric has a wide range of application potential in sports, protective clothing, etc. However, the existing unidirectional moisture-conducting fabrics on the market have defects such as non-durable functions, weak controllability, and slow moisture conduction speed.

At present, the main methods to achieve unidirectional moisture conduction are: 1. Use functional yarns; 2. Utilize the water conduction capacity of different yarns; 3. Utilize post-finishing methods; 4. Make the front and back sides have different water absorption properties through bonding.

Patent CN 207044828 U, "One-way moisture-conducting fabric", is a partially water-repellent yarn interwoven with raw cotton yarn and hydrophilic yarn, and the hydrophilic yarn count of the surface gauze is greater than that of the raw cotton yarn of the inner gauze, and no chemical treatment process is required, thereby reducing production costs.

Patent CN 110395019 A, "Process for preparing one-way moisture-conducting quick-drying fabric", uses flexible bamboo fibers and waterproof bamboo fibers to weave the inner layer of the fabric, and any two adjacent paths constituting the inner layer are connected to the outer layer of the fabric using flexible bamboo fibers to form the fabric.

Patent CN 109468774 A, "One-way moisture-conducting knitted fabric processing technology", performs hydrophilic treatment on the selected knitted fabric, performs water-repellent treatment on the hydrophilic treated fabric, and rolls and packages the knitted fabric after water-repellent treatment.

Patent CN 106827730 A, "A double-layer one-way moisture-conducting fabric and its application", discloses a double-layer one-way moisture-conducting fabric and its application, which is composed of two layers of fabric: a skin-friendly inner layer and an outer layer. The invention constructs a double-sided knitted fabric by designing the fabric structure and selecting functional and durable yarns, thereby achieving the one-way moisture-conducting effect of the fabric.

Patent CN 209798238 U, "One-time formed unidirectional moisture-conducting double-needle bed warp knitted fabric", discloses a one-time formed unidirectional moisture-conducting double-needle bed warp knitted fabric. The fabric is a three-layer mesh structure woven by a double needle bed warp knitting machine, including a water-blocking layer, a conductive layer, and a water-absorbing layer. The water-blocking layer and the water-absorbing layer are effectively connected by weaving back and forth with an intermediate comb. The one-time formed unidirectional moisture-conducting double needle bed warp knitted fabric has extremely good one-way moisture-conducting and perspiration-wicking effect, good air permeability, soft texture, and human body affinity.

Although the above patents have achieved the purpose of unilateral moisture conduction, there are still some shortcomings: Patent CN207044828 U is a partially water-repellent yarn made by interweaving raw cotton yarn and hydrophilic yarn, the production process is cumbersome, and the local water repellency will affect the overall effect of the fabric. At the same time, the raw cotton yarn will become hydrophilic and lose its function after multiple washings; Patent CN 110395019A uses special raw materials and has high production costs; Patent CN 109468774 A uses a post-finishing method to achieve the effect, but this effect will not always exist, but will gradually weaken with the use of clothes and washing until it disappears, and it is not conducive to environmental protection; Patent CN 106827730 A is composed of two layers of fabric, a skin-friendly inner layer and an outer layer of fabric, and uses functional and durable yarns, the production process is cumbersome and the production cost is high. Patent CN 209798238 U uses double needle bed weaving, the appearance of the fabric is relatively simple, and the controllability of the unilateral moisture conduction effect is poor.

DETAILED DESCRIPTION

In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

As shown in Figures 1-5, the present invention discloses a sports lace fabric with adjustable moisture conduction in the fabric thickness direction, including a fabric body woven by a multi-comb lace machine, the fabric body including three groups of yarns, namely, yarn Y1, yarn Y2 and yarn Y3, the fabric body is provided with an appearance layer 1 composed of a warp flat structure of yarn Y1, a pattern layer 2 composed of a weft insert structure of yarn Y3, and a skin-contacting layer 3 composed of a multi-needle variable warp flat structure of yarn Y2, the pattern layer 2 is located between the appearance layer 1 and the skin-contacting layer 3, the water conduction capacity of yarn Y1 is greater than the water conduction capacity of yarn Y2, so that the water conduction capacity of the appearance layer is greater than the water conduction capacity of the skin-contacting layer, the water conduction capacity of yarn Y3 is different from the water conduction capacity of yarn Y2, so that the water conduction capacity of the pattern layer is different from the water conduction capacity of the skin-contacting layer, the coverage area of the pattern layer on the fabric body is ≥20% and less than 100%, and there is a non-patterned area 4 on the fabric body. The pattern layer has a concave-convex area, which, as a pattern structure, can enhance the overall visual effect.

By selecting yarns Y1, Y2 and Y3 with different water conductivity, the appearance layer, skin-contacting layer and pattern layer with different water conductivity can be woven. The water conductivity of the yarn directly determines the water conductivity of the corresponding layer. By using yarns Y3 with different water conductivity, pattern layers with different water conductivity can be woven. The pattern layer is located in the area between the appearance layer and the skin-contacting layer. Therefore, pattern layers with different water conductivity will have different effects on the transfer of water, thereby producing different water conduction effects.

The different water conduction properties are explained below by using the ratios of the different water conduction capacities of the appearance layer, the skin-contacting layer, and the pattern layer.

The ratio of the water conductivity of the yarn Y1 and the yarn Y2 is greater than or equal to 2, that is, the ratio of the water conductivity of the appearance layer and the skin-contacting layer is set to K1:K2≥2. At this time, the water conductivity of the appearance layer is much greater than that of the skin-contacting layer, forming a unidirectional moisture-conducting structure in which the moisture of the skin-contacting layer is conducted from the skin-contacting layer to the pattern-free area and the appearance layer. The moisture on the skin-contacting layer will be quickly conducted to the appearance layer through the pattern-free area and finally discharged, that is, the unidirectional moisture-conducting function is realized in the pattern-free area.

The ratio of the water conductivity of the yarn Y3 to the yarn Y2 is greater than or equal to 2, and the ratio of the water conductivity of the yarn Y1 to the yarn Y3 is greater than or equal to 1. The corresponding water conductivity ratio of the pattern layer and the skin-contacting layer is set to K3:K2≥2, and the water conductivity ratio of the appearance layer and the pattern layer is set to K1:K3≥1, forming a unidirectional moisture-conducting structure in which the moisture of the skin-contacting layer is conducted from the skin-contacting layer to the pattern layer and the appearance layer. The water conductivity of the pattern layer is much greater than that of the skin-contacting layer, while the water conductivity of the appearance layer is slightly greater than that of the pattern layer. Therefore, the moisture on the skin-contacting layer will be orderly discharged first through the pattern layer and then through the appearance layer.

The ratio of the water conductivity of the yarn Y3 and the yarn Y2 is set to be less than 0.5, and the corresponding water conductivity ratio of the pattern layer and the skin layer is set to K3:K2＜0.5. The water conductivity of the pattern layer is much smaller than that of the skin layer, and the moisture of the skin layer is difficult to be transferred to the pattern layer, so that the pattern layer forms a moisture blocking structure that blocks the conduction of moisture from the skin layer to the appearance layer, and the moisture can only be directly transferred from the non-pattern area to the appearance layer for discharge.

The ratio of the water conductivity of the yarn Y3 to the yarn Y2 is between 0.5 and 1, and the corresponding water conductivity ratio of the pattern layer and the skin-contacting layer is set to 0.5≤K3:K2＜1, and the water conductivity of the pattern layer and the skin-contacting layer is set to a relatively close range, and the water conductivity of the pattern layer is slightly smaller than that of the skin-contacting layer, and the moisture of the skin-contacting layer can be conducted to the pattern layer. The concave-convex structure formed by the pattern layer increases the contact area between the moisture conducted to the pattern layer and the air, so that the moisture can evaporate quickly, thereby achieving the dryness and moisture absorption and sweat-wicking function of the skin-contacting layer.

The ratio of the water conductivity of the yarn Y3 to the yarn Y2 is set between 1 and 2, and the corresponding water conductivity ratio of the pattern layer and the skin-contacting layer is set to 1≤K3:K2＜2, forming a differentiated transfer structure of the skin-contacting layer moisture from the skin-contacting layer to the pattern layer and the appearance layer, and the moisture is differentially transferred from the inside to the outside. The differential transfer of moisture from the inside to the outside realizes the gradient unidirectional moisture conduction function of the fabric, and the visual effect of different color depths is presented due to the inconsistent degree of water absorption of the pattern after sweating.

The fabric body also includes yarn Y4, which is spandex yarn and has a weft insertion structure to form a shrinkage layer, thereby providing stretchability for the entire fabric body.

The weave structure of the yarn Y1 constituting the appearance layer is a two-needle warp plain structure, and its inlay yarn number is 1-2/1-0//; the weave structure of the yarn Y2 constituting the skin-contacting layer is a variable warp plain structure, and its inlay yarn number is 1-0/2-3//; the weave structure constituting the pattern layer is a weft lining structure, and its basic weave structure inlay yarn number is 0-0/1-1//.

The organizational structure of the yarn Y4 is a weft-inserted structure, the maximum number of needles for a single transverse shift is 5 needles, and the preferred inlay yarn number is 1-1/0-0//.

The Y1 is a filament or a composite yarn with a denier between 20-150D. The DPF of the yarn Y1 is less than 0.6, and is set to PES 75D/144F SD DTY.

The yarn Y2 is a filament or a composite yarn, with a denier between 20-150D, a DPF of Y2>1, and preferably PES 50D/48FSD DTY.

The yarn Y3 is a filament or a composite yarn, and the denier is between 40-840D.

As for the water conductivity of yarn Y1, yarn Y2, and yarn Y3, they can be directly selected based on existing products. For the same type of yarn, it only needs the water conductivity to meet the requirements.

By arranging the yarns Y3 with different water-conducting capabilities, the fabric can have different water-conducting capabilities.

The fabric is woven by a lace machine with a needle density of 14-28 per inch, and the specific production steps include:

1. Process design: Design the pattern draft according to the product requirements, and carry out process design and make process sheets based on the pattern draft.

2. Material preparation After selecting the loom and the yarn to be used according to the process requirements, the warping operator will prepare the raw materials on the bobbin according to the requirements of the process sheet, and the yarn used for the pattern comb will be prepared on the bobbin according to the requirements of the process sheet.

3. Yarn threading: The ground comb disc head is threaded onto the yarn guide needle of the corresponding comb bar, and the bobbin of the pattern comb yarn is threaded onto the yarn guide needle of the corresponding comb bar through the elastic sheet according to the process sheet and the comb bar arrangement table.

4. Adjust the tension and start the machine. After all the yarns are threaded as required, hang the cloth ends. Then adjust the yarn tension of each set of reels and each comb bobbin according to the design requirements and the actual situation on the machine to ensure that it is within a reasonable range. Then check whether there are other problems. After all problems are eliminated, you can start weaving.

5. Post-processing process: open width washing → pre-setting → overflow dyeing → finishing.
