Description

Technical Field

[0001] The invention relates to the technical field of fabric preparation, and in particular to a moisture absorbing and perspiration wicking fabric and a preparation method thereof. Background Art

[0002] As people's living standards continue to improve, people's functional requirements for fabrics are gradually increasing. For example, when people choose clothes in the hot summer, they tend to choose comfortable, high-quality, moisture-wicking, refreshing and dry fabrics. In order to improve the moisture-wicking performance of fabrics, porous fiber materials are often used on the market. The capillary phenomenon generated by the microporous grooves on the fiber surface allows sweat to diffuse and transfer, migrate to the fabric surface and disperse, so as to achieve the purpose of moisture conduction and quick drying of the fabric.

[0003] The moisture wicking fibers used in moisture wicking fabrics mainly utilize the fiber cross-section profiling to form grooves on the fiber surface. With the help of the wicking structure of the grooves, they quickly absorb moisture and sweat from the skin surface and quickly expel them from the body. The sweat is then diffused by the fibers on the surface of the fabric and quickly evaporated, thereby achieving the purpose of moisture wicking, regulating body temperature, and keeping the skin dry and cool.

[0004] There are two types of moisture wicking fabrics currently on the market: one has good wear resistance, but poor moisture absorption and moisture conductivity, and poor ability to extract moisture from the fabric; the other has good moisture absorption and sweat wicking properties, but sweat easily accumulates on the fabric and is difficult to clean. Summary of the invention

[0005] The object of the present invention is to reduce the influence brought by the above situation and to provide a moisture wicking fabric and a preparation method thereof.

[0006] To achieve the above object, the present invention adopts the following technical scheme: a method for preparing a moisture-absorbing and perspiration-wicking fabric, wherein the moisture-absorbing and perspiration-wicking fabric comprises two layers, wherein one layer comprises, by weight, 50-60 parts of pennywort fiber and 40-50 parts of polyester fiber; and the other layer comprises, by weight, 2-10 parts of costus fiber, 25-35 parts of modified hibiscus fiber, 25-30 parts of spandex and 30-35 parts of carbon fiber;

[0007] The modified hibiscus fiber is obtained by subjecting hibiscus fiber to hydrothermal treatment and alkalization treatment.

[0008] Preferably, a method for preparing a moisture wicking fabric comprises the following steps:

[0009] S1: Mixing pennywort fiber and polyester fiber as raw materials to form product A after mixing, feeding product A into the drafting area of ​​the spinning frame for drafting, spinning and weaving by siro spinning technology to form yarn A, and the yarn A is double-sided plain needle to form fabric A;

[0010] S2: mixing wood fragrance fiber, spandex and carbon fiber as raw materials to form product B;

[0011] S3: After removing impurities from hibiscus, washing and drying, hydrothermally treating and alkalizing the hibiscus fiber, the modified hibiscus fiber and product B are mixed in a mass ratio of 2:5 to form product C, the product C is fed into the drafting zone of the spinning machine for synchronous drafting, and a braiding machine is used to weave the yarn B, and the yarn B is double-sided plain needled to form fabric B;

[0012] S4: Fabric A and fabric B are combined to form a moisture wicking fabric.

[0013] Preferably, the hydrothermal treatment in step S3 is to first spray the hibiscus fiber with hot water at 95-100° C. for 0.5-1 h, then soak it in a hydrochloric acid solution at 20-35° C. for 2-3 hours, and then wash it with distilled water until it is neutral.

[0014] Preferably, the alkalization treatment in step S3 is to soak the hibiscus fiber in sodium hydroxide solution for 8-12 hours, control the pH value to 7.2-7.8, and obtain the modified hibiscus fiber after drying.

[0015] Preferably, the hydrochloric acid solution is 3.0 mol / L and the sodium hydroxide solution is 2.5 mol / L.

[0016] Preferably, in step S1, the yarn A has a double-sided plain needle horizontal density of 72.4 / 10 cm, a vertical density of 52.8 / 10 cm, a needle gauge of 11.5 G, and a gram weight of 365 g / m2.

[0017] Preferably, in step S3, the yarn A has a double-sided plain needle horizontal density of 72.4 / 10 cm, a vertical density of 52.8 / 10 cm, a needle gauge of 11.5 G, and a gram weight of 365 g / m2.

[0018] Preferably, the moisture wicking fabric is prepared by the above preparation method.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The fabric is formed by a double-layer composite, with fabric B being the side that fits the body. The modified hibiscus fiber is treated with hydrothermal treatment to remove bacteria, and the weak alkaline impurities that are easily detached from the surface of the hibiscus fiber are removed by acid washing. Subsequently, the weak acid on the hibiscus fiber is washed away with hydrochloric acid to ensure that the weak alkalinity on the hibiscus fiber remains longer. The moisture in the sweat is absorbed by the woody fiber, modified hibiscus fiber and spandex in fabric B, and the weakly alkaline modified hibiscus fiber is neutralized with the weakly alkaline sweat acid and alkali to prevent sweat stains from being contaminated on the fabric and making it inconvenient to wash. Since the water absorption capacity of the pennywort fiber is stronger than that of the woody fiber, modified hibiscus fiber and spandex, its moisture is attached to the fabric A, and its moisture absorption and perspiration removal effect is good, ensuring that the internal fabric B fits comfortably. At the same time, the modified hibiscus fiber has a good thermal insulation effect, the woody fragrance has a unique aroma, and it is anti-bacterial and anti-mosquito. The carbon fiber enhances the strength of the fabric A, and its sweat removal effect is better than that of the ordinary hibiscus fiber. DETAILED DESCRIPTION

[0055] In order to further illustrate the technical advancement of the present invention, experiments are now used to further illustrate.

[0056] Experimental method: The fabric samples prepared by Examples 1-3 and Comparative Example 1 were subjected to the following testing tests:

[0057] 1. According to GB / T21655.1-2008 Evaluation of Moisture Absorption and Quick-drying Properties of Textiles, the moisture absorption and quick-drying properties of each sample were measured. The specific test parameters were water absorption rate / %, moisture permeability, and drying rate.

[0058]

[0059] 2. According to FZ / T 73023-2006 antibacterial knitwear standard, the antibacterial rate / %, and sweat stain rate of each sample were determined.

[0060]

[0061] 3. According to GB / T3922-2013 Textile Color Fastness to Perspiration, measure the fabric sweat cleaning efficiency.

[0062] Cleaning times Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 1 99％ 95％ 98％ 98％ 98％ 3 99％ 95％ 98％ 98％ 88％ 5 98％ 94％ 98％ 93％ 79％ 7 98％ 93％ 97％ 89％ 70％ 9 97％ 93％ 97％ 85％ 62％

[0063] The moisture wicking fabric made in Example 1 of the present invention has excellent effects on water absorption, moisture permeability and drying rate, has good perspiration effect, and also has good antibacterial effect.

[0064] Comparative Example 1 uses traditional hibiscus fiber. After 7 washes, the sweat stain cleaning efficiency of the fabric is significantly reduced, that is, the alkaline material that is easily detached from the hibiscus fiber is lost, and the alkalinity is also gradually lost, causing the stain removal effect to begin to deteriorate. Comparative Example 2 uses potassium carbonate. After washing, the alkalinity is severely lost and the stain removal effect cannot be guaranteed.

[0066] In Comparative Example 2, hibiscus fiber was not used, resulting in greatly reduced water absorption, moisture permeability and drying rate of the close-fitting fabric B.

[0067] Conclusion: The fabric prepared by the present invention not only has excellent antibacterial properties, but also can keep the skin surface dry all the time through measuring the water absorption rate / %, moisture permeability and drying rate of the fabrics in the embodiments and comparative examples, and also has excellent moisture absorption and perspiration discharge effect, effectively realizes the moisture conduction function of the fabric, and is easy to remove sweat stains, and has high practicality.
