Description

Technical Field

[0001] The present invention relates to the field of textiles, and particularly to a non-sticky moisture-absorbing and quick-drying fabric and a preparation method thereof. Background Art

[0002] In recent years, running has become one of the increasingly popular sports. In the fabric of the clothing worn by runners (abbreviated as running clothes), the moisture-absorbing and quick-drying function of textile fabrics and the characteristic of whether they stick to the body after sweating are considered to be one of the most concerned functional features of consumers. The non-sticking property requires that the running clothes, on the basis of the moisture-absorbing and quick-drying function, also have the characteristic of not clinging to the wearer's body skin well. It has been found through research that when a person is at rest, the amount of sweat evaporated through the skin is about 20 - 50 g / h; when the activity intensity of the human body is too high or the environmental temperature is too high, in order to maintain body heat balance, the human body will secrete a large amount of sweat through the sweat glands for heat dissipation, and the amount of sweat is about 100 g / h. If the generated sweat cannot be diffused from the microenvironment formed between the clothing and the skin to the outside in time, moisture will accumulate in the microenvironment, resulting in the fabric sticking to the skin, and even making the human body feel wet and cold, seriously affecting the competition performance level of runners, etc. Therefore, using moisture-absorbing and quick-drying functional materials, combined with the three-dimensional structure design and process methods of the fabric, to develop textile clothing fabrics that can be used for running sports to better meet the requirements of runners for moisture-absorbing, quick-drying, and non-sticking functional properties is one of the research topics in the industry.

[0003] At present, the moisture-absorbing and quick-drying textile fabric products on the market mainly utilize the different moisture absorption rates of two or more fibers, and can achieve a better one-way moisture conduction effect by combining a double-layer fabric structure. However, they all have certain limitations. For example, the drying rate of the fabric is not high, mostly about 0.4 g / h; and most of them emphasize the moisture-absorbing and quick-drying performance of the product, without considering the non-sticking property of the product. Summary of the Invention

[0004] In view of this, the present invention provides a non-sticky moisture-absorbing and quick-drying fabric and a preparation method thereof. The moisture-absorbing and quick-drying knitted fabric provided by the present invention has a high drying rate, and can achieve good moisture-absorbing, quick-drying, and non-sticking functional characteristics.

[0015] The present invention provides a method for preparing the moisture-absorbing and quick-drying fabric as described above, including:

[0016] Knitting the first yarn and the second yarn according to a double-layer structure, and optionally performing dyeing and / or post-finishing processes to obtain a non-sticky moisture-absorbing and quick-drying fabric; the fineness of the first yarn is 100D-150D, the F number is 72F-144F, and it is mainly distributed in the next-to-skin layer of the fabric, and the surface of the next-to-skin layer has multiple raised structures evenly spaced;

[0024] In order to more clearly understand the technical features, purposes and effects of the present invention, the following will now detail the technical solutions of the present invention with reference to specific embodiments. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The present invention provides a moisture-absorbing and quick-drying fabric that does not stick to the body, including a skin-friendly layer and a surface layer formed by double-layer knitting. The fineness of the main yarn of the skin-friendly layer is 100D - 150D, and the F number is 72F - 144F. The fineness of the main yarn of the surface layer is lower than that of the main yarn of the skin-friendly layer, and the F number is 36F - 72F.

[0026] The surface of the skin-friendly layer has a plurality of convex structures evenly distributed at intervals; the main yarn of the surface layer has a cross-shaped profiled fiber cross-section.

[0027] The moisture-absorbing and quick-drying knitted fabric provided by the present invention has a high drying rate, and can achieve good moisture-absorbing, quick-drying and non-sticking functions. The fabric is dry, comfortable and conducive to application.

[0028] A knitted fabric is a fabric formed by bending yarns into loops and interlacing them with knitting needles, and is divided into weft knitting and warp knitting; in warp knitting, multiple yarns are simultaneously looped along the longitudinal (warp) direction of the fabric surface, and in weft knitting, one or more yarns are looped along the transverse (weft) direction of the fabric surface. Among them, weft knitted fabrics often adopt plain stitch, modified plain stitch, rib plain stitch, double rib plain stitch, jacquard stitch, terry stitch, etc., and are knitted on various weft knitting machines. Exemplarily, some embodiments of the present invention are weft knitted fabrics.

[0029] Fineness is a specification index describing the thickness of fibers or yarns, which has a certain influence on the strength, feel, etc. of textiles. Among them, the fineness D, also known as "denier" or (denier), refers to the number of grams of weight of 9000 meters of yarn or fiber under the condition of the official regain rate. It is a unit of constant length system, and the greater the gram weight, the thicker the yarn or fiber. The F number of yarns generally refers to the number of filaments in a single yarn for chemical fiber yarns; the measurement of the F number is mainly determined by observing the direction of the filaments in the yarn. If it is inclined from the upper left to the lower right, it is an S twist, and if it is inclined from the lower left to the upper right, it is a Z twist.

[0030] The knitted fabric provided by the embodiments of the present invention includes: a skin-friendly layer and a surface layer formed by double-layer knitting of yarns. When in use, the skin-friendly layer is close to the body and the surface layer is away from the body. The skin-friendly layer can also be called the bottom layer, inner layer, reverse side, etc., and the corresponding fabric surface layer can be the surface layer, outer layer, front side. Among them, the fineness of the main yarn of the skin-friendly layer is 100D - 150D (for example, 100D, 120D, 140D, 150D), the F number is 72F - 144F, and can be 80F, 96F, 122F, 144F, etc. The fineness of the main yarn of the surface layer is lower than that of the main yarn of the skin-friendly layer, preferably 50D - 75D (for example, 50D, 60D, 65D, 70D, 75D), and the F number is 36F - 72F, preferably 48F. The main yarn refers to the yarn distributed on a surface layer of the fabric.

[0031] Moreover, the main surface layer yarn has a cross-shaped profiled fiber cross-section; for the profiled fiber with a cross-shaped cross-section, the four angles of the circumscribed quadrilateral shape of the cross-section are the same, basically right angles, and it is sufficient that they are all in the range of 82-98°. Preferably, the specific surface area of the main surface layer yarn is 0.3-0.5 m 2 / g, specifically it can be 0.3925-0.4036 m 2 / g. The surface layer with a profiled fiber cross-section in this specific surface area range has a better effect on improving the sweat evaporation rate. At the same time, it cannot be ignored that the yarn specification ratio of the surface layer and the next-to-skin layer has a great influence on the sweat absorption surface and the diffusion (evaporation) surface.

[0032] Furthermore, the main next-to-skin layer yarn is a microporous carbon capture polyester yarn; its specific surface area can be 0.3-0.8 m 2 / g, specifically 0.3529-0.3780 m 2 / g. Even further, the main next-to-skin layer yarn is a microporous carbon capture polyester fiber with a moisture regain of 0.35-0.45%. In some embodiments of the present invention, the main surface layer yarn is a moisture-absorbing and sweat-wicking yarn with a moisture regain of 0.4-0.5% and a cross-shaped cross-section (which can be simply referred to as a cross-shaped absorbent and wicking yarn); the moisture regain of the main surface layer yarn can be higher than that of the main bottom layer yarn.

[0033] The moisture regain is an index indicating the moisture absorption degree of textile materials, expressed as the percentage of the weight of the moisture contained in the material to the weight of the dry material. In the trade of textiles, for the needs of weighing and price verification, it is necessary to make a unified regulation on the moisture regain of various textile materials, which is called the official moisture regain. Among common fibers, the official moisture regain of cotton is generally 8.5%, and that of ordinary polyester is 0.4%.

[0034] The material of the microporous carbon capture polyester yarn described in the embodiments of the present invention is a polyester such as polyethylene terephthalate synthesized from the alcohol converted from the captured and collected carbon dioxide as the raw material. The fibers of the spun microporous polyester yarn have multiple micropores. The cross-shaped absorbent and wicking yarn can absorb moisture to a certain extent and has good moisture wicking performance, and it is mainly made of polyester.

[0035] In some preferred embodiments, in the non-sticky moisture-absorbing and quick-drying fabric, the main next-to-skin layer yarn includes 100D / 72F microporous carbon capture polyester yarn, and the main surface layer yarn is 75D / 48F cross-shaped profiled fiber cross-section yarn. The preferred embodiments of the present invention utilize the hydrophilicity difference between the microporous carbon capture polyester fiber and the cross-shaped absorbent and wicking polyester fiber, combined with the convex design of the reverse weaving structure of the fabric, so that the fabric has good moisture-absorbing and quick-drying performance and does not stick to the skin after absorbing a large amount of moisture.

[0036] The embodiments of the present invention also design the length of the yarn for the fabric, which has a great influence on the hand feeling of the finished fabric and the presentation form of the fibers in the fabric, and further affects the overall functional effect. The preferred lengths of the yarns used in the moisture-absorbing and quick-drying fabric include: the main yarn of the close-fitting layer is 23-25 cm / 100G, and the main yarn of the surface layer is 27.5-28.5 cm / 100G.

[0037] The embodiments of the present invention optimize the combination of functionalized yarns and the three-dimensional structure of knitted fabrics to achieve the performance of moisture absorption, quick drying, and non-sticking to the body, including: the hydrophilic differences of yarns with different specifications and structures, and a certain difference in the moisture regain rate between the coils of the close-fitting layer and the surface layer adopted, so as to achieve the capillary pressure difference between the two layers of yarn fabric layers, enabling sweat to quickly diffuse from the close-fitting layer to the surface layer through the capillary effect.

[0038] In the embodiments of the present invention, the surface of the close-fitting layer has a plurality of convex structures evenly distributed at intervals; its specific distribution is a plain weave coil pattern (which can be called a "checkerboard-style" convex structure distribution configuration; affected by the thickness and length of the yarn, some yarns are tightened and some coils bulge, thus forming a unique plain weave style), and the total maximum area of the convex structures preferably accounts for 60%-75% of the entire surface area.

[0039] The embodiments of the present invention combine the convex design of the reverse weaving structure of the fabric. Preferably, the close-fitting layer adopts a "checkerboard-style" convex structure distribution, and uses the difference in the linear density of two yarns to form a regular convex structure, so that the fabric wetted by sweat contacts the human skin in a point-like manner, minimizing the contact area between the fabric and the human body to the greatest extent, so that the fabric will not adhere to the skin, and can continuously conduct sweat from the sweating skin surface to keep the comfort of the human body wearing.

[0040] Correspondingly, the present invention provides a preparation method of the moisture-absorbing and quick-drying fabric as described above, including:

[0041] Knitting the first yarn and the second yarn according to a double-layer structure, and optionally performing dyeing and / or post-finishing processes to obtain a non-sticking moisture-absorbing and quick-drying fabric; the fineness of the first yarn is 100D-150D, and the F number is 72F-144F, which is mainly distributed in the close-fitting layer of the fabric, and the surface of the close-fitting layer has a plurality of convex structures evenly distributed at intervals; the fineness of the second yarn is lower than that of the first yarn, the F number is 36F-72F, and it has a cross-shaped profiled fiber cross-section and is mainly distributed in the surface layer of the fabric.

[0042] The embodiments of the present invention are in accordance with Figures 1 to 3 The shown knitted fabric organizational structure, and use the yarns corresponding to the close-fitting layer and the surface layer for weaving on the loom to obtain the moisture-absorbing and quick-drying fabric.

[0043] Figure 1 is a coil diagram,Figure 2 It is the pattern design drawing of the back stitch pattern, Figure 3 which is the knitting diagram; Figure 1 and Figure 3 in [figure], 1 to 6 correspond to their respective yarn paths, Figure 2 showing a back stitch plain knitting structure, and the blank squares correspond to cross suction and drainage yarns.

[0044] The knitted fabric obtained by weaving can also be subjected to subsequent processes such as dyeing and post-finishing, and there are no special restrictions in this application. For example, using a conventional disperse dyeing process, the dyeing temperature can be between 120 - 130 °C, and the pH value of the dye bath is 4 - 5.

[0045] The drying rate of the moisture-absorbing and quick-drying fabric described in the embodiments of the present invention can reach 0.52 g / h, and it can achieve good moisture-absorbing and quick-drying and non-sticking functional characteristics. When it is worn, it can quickly evaporate sweat, effectively avoid the accumulation of sweat inside the textile, reduce the adhesion between the fabric and the human skin after the sweat accumulates, and the use experience is better.

[0046] To better illustrate the present invention, further examples are given below through embodiments. In the embodiments, all original reagents and materials can be obtained commercially, and the experimental methods without specific experimental conditions are conventional methods and conditions well-known in the art.

[0047] Example 1

[0048] The specific steps of the method for preparing a non-sticking moisture-absorbing and quick-drying fabric of the present invention are as follows:

[0049] According to Figures 1 to 3 the double-layer structure shown, using commercially available yarns for weaving on the loom, and the loom process is: 28G 34 inches; yarn length: 100D / 72F multi-hole carbon capture yarn 24 cm / 100G, 75D / 48F cross moisture-absorbing and sweat-discharging yarn 28.5 cm / 100G.

[0050] Yarn: The next-to-skin layer is composed of 100D / 72F multi-hole carbon capture yarn (polyester yarn, specific surface area 0.3529 - 0.3780 m 2 / g, moisture regain 0.35 - 0.45%) and 75D / 48F cross high moisture-absorbing performance yarn (due to the influence of the structural coil, there is this moisture-absorbing yarn, which makes moisture conduction easier, but at the same time does not affect the non-sticking effect), configured in a "checkerboard" distribution; the outer layer is woven from 75D / 48F cross moisture-absorbing and sweat-discharging yarn (specific surface area 0.3925 - 0.4036 m 2 / g, moisture regain 0.4 - 0.5%). The test results of the yarn indexes include: specific surface area: multi-hole carbon capture yarn 0.3659 m 2 / g; cross suction and drainage yarn 0.3947 m 2 / g. Moisture regain: 0.4% for the porous carbon capture yarn and 0.45% for the cross absorbent and discharge yarn (there may be slight differences due to test deviations).

[0051] After weaving, the obtained knitted fabric is dyed. The dyeing process curve is shown in Figure 4 (The dyeing formula is as follows, bath ratio 1:50). Dyeing starts from room temperature (20 - 30 °C), heats up to 90 °C at a rate of 2 °C / min, then heats up to 125 °C at a rate of 1 °C / min, and holds for 30 min. Then it is cooled to room temperature, washed with cold water, soaped, washed with water, and dried to obtain the finished moisture-absorbing and quick-drying fabric.

[0052] The dyeing formula includes:

[0053] Disperse Ruby SE-GFL 2% (on the weight of the fabric owf);

[0054] Diffusing agent NNO 1 g / L;

[0055] Ammonium dihydrogen phosphate 2 g / L;

[0056] Adjust the pH to 4 - 5 with acetic acid.

[0057] In addition, according to Example 1, under the same yarn count specifications and structure of the present invention, by adjusting the yarn length, the corresponding finished moisture-absorbing and quick-drying fabric can be obtained.

[0058] The comparison results of the performance of the fabric are as follows:

[0059] 1. Testing the fabric according to the national standard GB / T 21655.1 - 2023, the moisture-absorbing and quick-drying results of the examples are shown in the following table.

[0060] Table 1 Test results of Example 1

[0061] Inspection Items Standard Values and Tolerances Inspection Results Judgment Drip Diffusion Time before Washing / s ≤2 (Grade III) ＜1 Complies Drip Diffusion Time after Washing / s ≤2 (Grade III) ＜1 Complies Water Absorption before Washing / % ≥160 (Grade III) 189 Complies Water Absorption after Washing / % ≥160 (Grade III) 197 Complies Wicking Height before Washing / mm ≥120 (Grade III) 173 Complies Wicking Height after Washing / mm ≥120 (Grade III) 212 Complies Drying Rate before Washing / g / h ≥0.42 (Grade III) 0.47 Complies Drying Rate after Washing / g / h ≥0.42 (Grade III) 0.52 Complies

[0062] According to the above table: All indicators of the moisture-absorbing and quick-drying fabric in Example 1 can reach the third level of the national standard, and the drying rate after washing is even as high as 0.52 g / h. It can be seen that this fabric has excellent moisture-absorbing and quick-drying properties.

[0063] 2. After completely wetting the fabric with sweat, the force value required to separate the fabric from the simulated skin is only 0.7 N (verified by trial wearing, fabrics with < 1 N do not stick to the body after running and sweating). It can be seen that the fabric has very good non-sticking properties.

[0064] 3. Handfeel:

[0065] The fabric obtained in Example 1 has a dry and comfortable handfeel, does not stick to the body during actual wearing, and is very suitable for running.

[0066] As can be seen from the above embodiments, the moisture-absorbing and quick-drying knitted fabric of the present invention has an optimized combination of a functional yarn and a double-layer or multi-layer structure of the knitted fabric, which can achieve the functions of moisture absorption, quick drying and non-sticking of the fabric. The fabric is dry and comfortable, and is very suitable for making running clothes. When the non-sticking moisture-absorbing and quick-drying knitted fabric developed by the present invention is worn, the side of the close-fitting layer close to the skin and the side of the surface layer far from the skin can enable sweat to evaporate quickly, effectively avoid the accumulation of sweat inside the textile, and reduce the adhesion between the fabric and the human skin after the sweat accumulates. The drying rate of this fabric can reach 0.52 g / h, far exceeding the industry level, and can remain non-sticky after a large amount of sweating.

[0067] The above examples are only used to illustrate the technical features and implementation process of the present invention, rather than limiting the technical solutions of the present invention. It should be pointed out that for those of ordinary skill in the art, the present invention can still be modified or equivalently replaced, and any modification or replacement that does not depart from the principle of the present invention is covered by the protection of the present invention.
