Description

Preparation of a polyester and spandex blended moisture-absorbing and sweat-wicking high-elasticity and breathable fish scale fabric

technical field

The invention belongs to the field of preparation of moisture-absorbing and sweat-wicking fabrics, and particularly relates to a preparation method of a polyester and spandex blended moisture-absorbing and sweat-absorbing high-elasticity and breathable fish scale fabric.

Background technique

With the improvement of people's living standards, the advancement of science and technology and the change of consumption concept, the requirements for clothing, food, housing and transportation are also getting higher and higher. Comfort is a key factor for people to buy clothing, so functional fabrics are getting more and more attention. Moisture-absorbing cool fabrics are daily necessities closely related to people's lives. They are usually made of non-absorbent polyester fibers and elastic spandex blends. interwoven. Through the machine, the strands in the fabric are pulled out of the fabric according to a certain rule and a certain length of fibers, so it has good moisture absorption and quick-drying performance. Soft to the touch, it is one of the most used sports fabrics. In addition to meeting the basic functions of clothing, the moisture-absorbing and sweat-wicking fabric can discharge sweat in time, and will not feel wet and cold due to the clothes sticking to the skin, which greatly enhances wearing comfort and improves people's quality of life. Moisture-wicking fabrics, often referred to as "moisture-wicking fabrics" or "breathable fabrics," are woven from moisture-wicking fibers. Moisture-absorbing and perspiring fibers generally have a high specific surface area, with numerous holes or grooves on the surface. The capillary effect generated by the micro-grooves on the surface enables the fibers to quickly absorb moisture and sweat on the skin surface, and through wicking and diffusion, It is quickly transferred to the outer layer of the fabric and spreads out, so as to achieve the purpose of quick drying. When the wearer is engaged in a large amount of physical activity or productive labor, the sweat can quickly wet the fabric, and the sweat can diffuse on the surface and inside of the fabric by the capillary formed between the yarns and the single fibers that constitute the fiber assembly. With the increase of the diffusion area, sweat can quickly evaporate to the surrounding environment, that is, while wetting, diffusing, and evaporating, there will be no uncomfortable feeling of clothing sticking to the body. This requires that the fibers constituting the moisture-wicking-quick-drying functional fabric have a reasonable chemical and physical structure. Even if the clothes belong to the same moisture absorption-perspiration-quick-drying function, there are still different needs in different occasions. For example, in general slow running, fast walking or light physical labor, it is more appropriate to wear a thin single-layer moisture-wicking fabric casual sportswear. In the occasions where you are involved in a large amount of exercise or engage in heavy physical labor, it is more suitable to wear moisture-wicking clothing with a double-layer structure.

Polyester and spandex are two kinds of raw materials commonly used in textile production. Their blended products not only have excellent elasticity, warmth retention, dyeing properties, and practicality, but also give the human body a good tactile effect when wearing clothing. According to preliminary statistics, the proportion of polyester and ammonia in textile composition analysis accounts for 12%, so polyester and ammonia blended products are very important.

The present invention also provides an application of the fish scale fabric prepared by the above method.

The invention realizes the effect of moisture absorption and perspiration by combining single-layer fabric and double-layer fabric, and has high elasticity and air permeability. In the design, the inner warp and surface warp of the double-layer fabric are respectively hydrophobic and hydrophilic polyester yarns. Thread, hydrophilic polyester yarn is used as the surface weft, and hydrophobic polyester yarn is used as the inner weft, which is woven to achieve the function of moisture absorption and perspiration. The warp in the single-layer fabric is woven with elastic spandex, and the inner weft in the double-layer structure Together with the surface weft, it is the weft in the single-layer fabric, and this structure makes the fabric highly elastic and breathable. The width of double-layer fabric: the width of single-layer fabric = 5:1 (weaving with 6 cm as a cycle), the results show that the performance of developing hygroscopic and quick-drying fabrics by this method can reach the development of traditional methods.

The principle of the fish scale fabric prepared by the present invention is as follows: as shown in Figure 1, the inner layer 1 of the fabric is hydrophobic finishing polyester fiber, the outer layer 2 is hydrophilic finishing polyester fiber, 3 is spandex fiber, and the surface weft 5 is hydrophilic polyester fiber, Inside weft 4 is hydrophobic polyester fiber. The warp and weft polyester and ammonia fibers are woven separately, then tucked, repeated three times with floating thread weaving, and continuously woven in a loop to form a fish-scale-like sheet structure arrangement; the fibers woven by the back-feeding thread cover the former to form a staggered fish-scale-like surface layer and inner layer. Due to the wicking effect, when the sweat touches the hydrophobic fibers in the inner layer of the fabric, it is transferred to the hydrophilic fibers in the outer layer, and further diffuses in the hydrophilic fibers, increasing the evaporation area, thereby achieving moisture wicking, moisture absorption and quick drying. In addition, the part of the single-layer structure is loosely woven, which can increase the breathability and elasticity of the fabric.

The present invention will be further described below in conjunction with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

Example 1

Impregnating the yarn for 30min (hydrophilic modifier or hydrophobic modifier)→pre-baking (80℃, 2min)→baking (150℃, 1min).

Specifically:

Step 1: Preparation of hydrophilic or hydrophobic modification solution: Mix 6g of hydrophilic agent KC-3 (Zhejiang Kefeng Silicone Co., Ltd.) or hydrophobic agent KF-407 (Zhejiang Kefeng Silicone Co., Ltd.) with 100 mL of water , and stirred at 30 ° C for 10 min to make it uniformly dispersed.

Step 2: After dipping the polyester yarn into the solution for 30 minutes (10:1), take out the yarn and pre-bake it at 80°C for drying, and then put it in an oven at 150°C for 1 minute.

The third step: as shown in Figure 1, use the treated yarn to perform mixed weaving of single-layer and double-layer fabrics. As shown in Figure 1, the inner layer 1 of the fabric is a hydrophobic finishing polyester fiber, the outer layer 2 is a hydrophilic finishing polyester fiber, and 3 It is spandex fiber, the surface weft 5 is hydrophilic polyester fiber, and the inner weft 4 is hydrophobic polyester fiber. The warp and weft polyester and ammonia fibers are woven separately, then tucked, repeated three times with floating thread weaving, and continuously woven in a loop to form a fish-scale-like sheet structure arrangement; the fibers woven by the back-feeding thread cover the former to form a staggered fish-scale-like surface layer and inner layer. The fish scale fabric is obtained, the double-layer fabric is polyester yarn, the single-layer fabric is spandex yarn, and the width of single-layer: width of double-layer=1:10.

Example 2

The immersion time in Example 1 was changed to 60min, and the rest were the same as those in Example 1 to obtain a fish scale fabric.

Example 3

Ultrasonic was carried out while dipping in Example 1, and the rest were the same as in Example 1 to obtain a fish scale fabric.

Example 4

Ultrasound was carried out while dipping in Example 2, and the rest were the same as those in Example 2 to obtain a fish scale fabric.

Comparative Example 1

Except for the factors in the table, the rest are the same as in Example 1. The water absorption time and water retention rate of Examples 1-4 and this comparative example are shown in Table 1. Unfinished and specially woven polyester quick-drying blank samples were used as a comparison, and the water absorption time and water retention rate of the blank samples were 6-8min and 30-40%, respectively. Water absorption According to JIS L1907-2010 "Test method for water absorption of textiles", the time for water droplets to be absorbed by the fabric (water absorption time) was measured by the dropping method.

Prepare a 10cm×10cm fabric sample and re-moisturize it for more than 1 hour in a standard state (temperature 20°C, humidity 65%), record its mass as W, drop 0.6mL of water on the sample, and begin to weigh the total mass of the sample W _1. Hang the sample, weigh the sample mass W ₂ every 5±0.5min, and calculate the moisture retention rate. The formula is as follows:

Moisture retention rate (%)=[(W ₂ −W)/(W ₁ −W)]×100%.

Table 1

The shorter the water absorption time, the better the hygroscopicity of the fabric. The moisture retention rate of the fabric was measured after 1 hour. The lower the moisture retention rate, the better the air permeability of the fabric and the quick drying. It can be seen from Table 1 that the hygroscopicity and air permeability of the fabric increase with the increase of the concentration of the reagent. The higher the proportion of the double-layer fabric, the higher the moisture absorption and air permeability. Moisture absorption and breathability are slightly improved. Among the examples, the water absorption time and the moisture absorption retention rate of Example 4 are the lowest, and the moisture absorption and air permeability are good.
