Description

Technical Field

[0001] The invention relates to the technical field of antibacterial fabric preparation, in particular to a moisture-absorbing and quick-drying antibacterial fabric and a preparation process thereof. Background Art

[0002] Antibacterial fabric refers to fabric that has the function of inhibiting the proliferation of surface bacteria. This kind of fabric can effectively prevent bacterial regeneration and reproduction, keep the fabric clean, and improve the comfort and health of the wearer. The main purpose of antibacterial fabric is to eliminate the adverse effects caused by the attachment and reproduction of microorganisms on textiles, including harm to human health and pollution to fibers. There are currently two mainstream antibacterial fabric processing technologies on the market: the first is built-in silver ion antibacterial fabric, which uses spinning-level antibacterial technology to directly integrate antibacterial agents into chemical fibers to give them a lasting antibacterial effect; the second is post-processed antibacterial fabric, that is, adding antibacterial agents through the subsequent shaping process of the fabric. This process is relatively simple and cost-controllable, and is the most widely used one on the market.

[0003] With the continuous advancement of fabric production technology, traditional antibacterial fabrics have gradually failed to meet people's needs, and more and more new antibacterial fabrics have emerged. For example, the patent document with publication number CN115434062B discloses a method for preparing moisture-wicking antibacterial fabrics. The moisture-wicking antibacterial fabric of the invention has excellent moisture-wicking and antibacterial properties, comfort and durability, and its preparation process is simple and green. It adopts low-temperature plasma modification treatment to introduce hydrophilic groups, which gives the hygroscopic fiber more excellent hydrophilicity, enhances the moisture absorption and quick-drying ability of the fabric, and greatly improves the water-washing resistance of the fabric.

[0004] However, in the actual preparation process, since polyester (polyester fiber) is one of the main components of many moisture-absorbing and quick-drying fabrics, but its own hygroscopicity is poor, when the polyester component accounts for a large proportion, the moisture absorption and quick-drying effect of the fabric will be affected. In order to strengthen the fabric, the antibacterial fabric is often woven more tightly, which will lead to a decrease in air permeability, thereby affecting the evaporation and discharge of moisture, making it difficult for the fabric to dry quickly after absorbing moisture, reducing its quick-drying performance.

[0005] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and shortcomings, and provides a moisture-absorbing and quick-drying antibacterial fabric and a preparation process thereof. Summary of the invention

[0006] The object of the present invention is to provide a moisture-absorbing and quick-drying antibacterial fabric and a preparation process thereof, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] On the one hand, a moisture-absorbing and quick-drying antibacterial fabric is provided, comprising an inner fabric and an outer fabric, wherein the inner fabric is fixedly connected to the outer fabric by hot pressing and compounding, the inner fabric comprises a first warp thread, a second warp thread, a first weft thread and a second weft thread, and the inner fabric is woven from the first warp thread, the second warp thread, the first weft thread and the second weft thread, the outer fabric comprises a first composite yarn and a second composite yarn, and the outer fabric is woven from the first composite yarn and the second composite yarn.

[0009] Furthermore, the first warp thread and the second warp thread together constitute the warp thread of the inner layer fabric, and the warp threads are arranged so that one first warp thread and two second warp threads alternately reciprocate, and the spacing between any two adjacent threads is the same.

[0010] Furthermore, the first weft line and the second weft line together constitute the weft line of the inner layer fabric, and the weft lines are arranged so that one first weft line and two second weft lines alternately reciprocate, and the spacing between any two adjacent lines is the same.

[0011] Furthermore, the number of the composite yarns one and the number of the composite yarns two are completely consistent, and the composite yarns one and the composite yarns two are spaced apart and interlaced with each other.

[0012] On the other hand, a preparation process of a moisture-absorbing and quick-drying antibacterial fabric is provided, which is applied to the moisture-absorbing and quick-drying antibacterial fabric as described above, and comprises the following steps:

[0013] S1, respectively, mixing silk fiber with bamboo charcoal fiber and pure cotton fiber in proportion and spinning to obtain warp one and warp two, and respectively mixing silk fiber with pure cotton fiber and silver fiber in proportion and spinning to obtain weft one and weft two;

[0014] S2, using machine weaving to interweave the warp line, the warp line, the weft line, the weft line into the inner layer fabric;

[0015] S3, spinning the hemp fiber and the bamboo fiber in different mass ratios to obtain composite yarn 1 and composite yarn 2 in sequence;

[0016] S4, weaving the composite yarn 1 and the composite yarn 2 to form an outer fabric;

[0017] S5. The inner layer fabric and the outer layer fabric are bonded together by hot pressing to obtain the antibacterial fabric.

[0018] Furthermore, in step S1, the specific preparation steps of warp one and warp two are: silk fiber and bamboo charcoal fiber are mixed and spun at a ply ratio of 3:2 to obtain warp one, and silk fiber and pure cotton fiber are mixed and spun at a ply ratio of 2:1 to obtain warp two.

[0019] Furthermore, in step S1, the specific preparation steps of the weft line one and the weft line two are: silk fiber and pure cotton fiber are mixed and spun at a ply ratio of 3:2 to obtain the weft line one, and silk fiber and silver fiber are mixed and spun at a ply ratio of 2:1 to obtain the weft line two.

[0020] Furthermore, in step S2, the first warp thread, the second warp thread, the first weft thread, and the second weft thread adopt a plain weave structure and are interwoven according to a ratio of 1:2:1:2.

[0021] Furthermore, in step S3, the specific preparation steps of weft one and weft two are: mixing and spinning the hemp fiber and bamboo fiber in a mass ratio of: to obtain composite yarn one, and mixing and spinning the hemp fiber and bamboo fiber in a mass ratio of: to obtain composite yarn two.

[0022] Furthermore, in step S4, the composite yarn 1 and the composite yarn 2 adopt a plain weave structure and are interwoven at a mass ratio of 5:3.

[0023] The present invention provides a moisture-absorbing and quick-drying antibacterial fabric and a preparation process thereof, which has the following beneficial effects:

[0024] 1. The antibacterial fabric proposed by the present invention is formed by hot-pressing and compounding an inner fabric and an outer fabric. The inner fabric is mainly composed of silk fiber, which is interwoven with yarns obtained by mixing and spinning silk fiber with bamboo charcoal fiber, pure cotton fiber and silver fiber in a certain proportion. While ensuring its skin-friendliness, it has a good antibacterial effect and can quickly discharge the absorbed sweat to the outer fabric. The outer fabric is interwoven with yarns obtained by mixing and spinning hemp fiber and bamboo fiber in different mass ratios. The high air permeability and evaporation of hemp fiber are used to quickly dissipate sweat. The antibacterial effect is enhanced by combining with bamboo fiber, which helps to reduce the odor problem caused by long-term wearing, avoids the breeding of bacteria due to sweat staying on the skin for a long time, and reduces the risk of skin infections such as acne, prickly heat and other skin diseases.

[0025] 2. The present invention designs the weaving structure of the inner fabric and the outer fabric, wherein the warp and weft of the inner fabric are woven by regularly arranging yarns with different diameters, which can naturally form uniform pores, avoid the problem of tight weaving, and can effectively promote the moisture absorption and perspiration of the fabric. At the same time, the outer fabric is woven by interlacing composite yarn 1 and composite yarn 1 which have high moisture absorption and quick-drying properties, and the two yarns have different diameters, so that the outer fabric can present a more porous three-dimensional structure. The design of the yarn weaving direction being forty-five degrees with the yarn weaving direction of the inner fabric effectively staggers the pores of the inner fabric and the outer fabric, thereby improving the moisture absorption and perspiration effect of the fabric from the physical structure. It is particularly suitable for high-intensity sports, outdoor sports and other occasions that require quick perspiration and drying. It can quickly discharge and evaporate sweat to keep the body dry and comfortable during intense exercise.

[0026] 3. The inner and outer fabrics of the present invention are interwoven with a plain weave structure, and the silk fibers, pure cotton fibers and other fibers used in the blending are also relatively mature limited categories in the prior art. There is no need to use additives to modify the yarns and fabrics. The performance improvement is mainly based on the optimization of the physical structure. The overall preparation process is relatively simple and more environmentally friendly, which is conducive to the mass production of the antibacterial fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Comparative Example 1

[0045] The antibacterial fabric is prepared by adopting the preparation method of the moisture wicking antibacterial fabric disclosed in the patent document with publication number CN115434062B.

[0046] Comparative Example 2

[0047] The antibacterial fabric was obtained directly through procurement. The fabric model is: 40s single-sided pure cotton fabric 7A antibacterial knitted fabric, purchased from Fentengkefang Ruijin Textile Co., Ltd.

[0048] Experimental testing

[0049] The evaluation of moisture absorption performance adopts the combination method involved in the national standard GB / T21655.1-2008 "Evaluation of moisture absorption and quick-drying properties of textiles Part 1: Single combination test method". The moisture absorption and quick-drying performance of the fabric are comprehensively evaluated by testing the wicking height and moisture permeability of the fabric.

[0050] (1) Wicking height test

[0051] The test was conducted according to the test steps of FZT01071-2008 "Test Method for Capillary Effect of Textiles". In a standard environment (temperature 20±2℃, humidity 65±3%), the fabric was cut into 3 samples with a length of 300mm and a width of 30mm. A 3g tension clamp was clamped at the lower end of the fabric to stretch the fabric vertically. The upper end of the fabric was fixed on the top of the capillary effect tester. After 30 minutes, the diffusion height of the watermark on the sample was recorded. The experiment was conducted 3 times, and the average value of the 3 experiments was finally taken. The experimental results are as follows: Figure 5 shown.

[0052] (2) Moisture permeability test

[0053] The moisture permeability is determined according to GB / T12704.1-2009 "Test method for moisture permeability of textile fabrics Part 1: Moisture absorption method". The test conditions are 38±2℃ and humidity is 90±2%. The moisture permeability of the fabric is calculated by the moisture absorbed by the desiccant in the moisture permeability cup within a fixed time. The test specimen is required to be a circular specimen with a diameter of 9.5cm, 3 specimens for each variety, and each specimen is tested once. Place the fabric on the moisture permeability cup with the hygroscopic surface in contact with the external environment. After sealing, place it in the WVTR-W3 computerized fabric moisture permeability meter for 1 hour, then cover the cup with the lid and place it in a drying dish to balance for 30 minutes, weigh it, and record it as the original weight. Then place it in the test box for moisture permeability balance for 1 hour, weigh it again, and record the weight. The moisture permeability is calculated according to the formula, and the test results of the three specimens are averaged. The experimental results are as follows Figure 6 shown.

[0054] The formula for calculating moisture permeability is as follows:

[0055] WVT=Δm / (A·t)1

[0056] Where: WVT - moisture permeability, moisture permeability per square meter per day (24h) [g / (m 2 24h)];

[0057] t——test time (h);

[0058] Δm——the difference between two weighings in the same group of tests (g);

[0059] A——Test area of ​​sample (m 2 ), this experimental device is 0.00283m 2 .

[0060] (3) Quick-drying performance test

[0061] The test conditions are 25±2℃, air humidity 35%RH, use a spray bottle to spray 30ml of pure water evenly on the surface of three varieties of sample cloth (each variety of sample includes five pieces, and each sample cloth is cut into a disc with a diameter of 10 cm in advance), and use an induction moisture meter to detect the moisture content of the cloth to obtain the quick-drying performance results of different varieties of sample cloth. The test results of five samples of each variety are averaged. The experimental results are as follows Figure 7 shown.

[0062] In summary, combined Figure 5-Figure 7 The test results of the experiments shown in the figure show that the antibacterial fabric prepared in Example 1 is significantly better than the fabrics prepared in Comparative Examples 1 and 2 in terms of wicking height, moisture permeability and quick-drying performance.

[0063] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
