Description

A lightweight stretch fabric

technical field

The utility model relates to a light elastic fabric, in particular to a light elastic fabric used in the production of sportswear in the textile industry.

Background technique

Today, when sports, leisure and comfortable life are advocated, stretch fabrics are not only used in sportswear, gym suits, etc., but also more and more stretch fabrics are used in underwear, outerwear, suits, etc. in daily life. After the Olympic Games in 2000, elastic fabrics became the focus of fashion. The annual market growth rate of elastic fabrics in the world is about 10%, while that in the Asia-Pacific region is as high as 15%. The biggest feature of elastic fabric is that it is elastic, comfortable to wear, free to move, and can show the beauty of human body curve to the maximum. To obtain such fabric, spinning elastic fabric is a key step.

The yarn used in sportswear is required to have three elements of warmth, comfort, and thinness, and the warmth and comfort requirements of the fabric must be taken into account. If consideration is given to preventing heat loss to improve warmth retention, it may affect comfort indicators such as air permeability and moisture permeability; The warmth retention and thinness requirements of the fabric cannot be balanced, because the thinner the fabric is, the more unfavorable it is for warmth retention; the comfort and thinness requirements of the fabric cannot be balanced, because the fluffy and fluffy structure required for comfort will increase the thickness of the fabric. This shows that it is very difficult to take into account the above three elements in conventional fabrics.

This product also uses bamboo fiber as another fabric fiber. Bamboo fiber belongs to regenerated cellulose fiber. The cross-sectional shape of bamboo fiber is similar to that of viscose, but the difference is that the cross-section is porous, so bamboo fiber has excellent hygroscopicity and moisture release. The fiber has excellent colorability and bright colors: the drapability is as good as viscose; the resilience and wear resistance are better than viscose: the biggest feature of the fiber is that it has natural antibacterial and antibacterial properties that other fibers do not have. Because bamboo itself has antibacterial function and is not attacked by insects during the growth process, bamboo fiber has natural antibacterial function without adding any antibacterial agent. After testing, bamboo fiber has antibacterial function against Escherichia coli, Staphylococcus aureus, Bacillus megaterium, Pseudomonas fluorescens, and Bacillus subtilis, and the 24-hour antibacterial rate is 73%. It is because of this unique performance that bamboo fiber has a wide range of applications.

To sum up, we need to optimize the structure of traditional yarns and combine existing technologies to solve the above technical problems.

Utility model content

The purpose of the utility model is to provide a lightweight elastic fabric that can solve the above problems in the prior art, has reasonable structural design, light weight, good thermal performance, moisture absorption and perspiration, and is environmentally friendly and antibacterial.

The utility model purpose is realized through the following technical solutions:

A lightweight elastic fabric, which is made up of fine warp yarns and thick weft yarns, is characterized in that the fine warp yarns are elastic yarns, and there are two strands of the fine warp yarns in the same warp direction, which are respectively the first fine warp yarn and the second fine warp yarn , the center locus of the first fine warp yarn and the second fine warp yarn is a space spiral, and the two strands of yarn are respectively interlaced and wound on the thick weft yarn according to the spiral channel; the thick weft yarn is composed of bamboo fiber yarn spirally wound outside the nylon yarn; Nylon yarn is twisted by nylon monofilament; the outer contour of the cross-section of the nylon monofilament is surrounded by four end-to-end arc lines; the nylon monofilament is provided with two hollow cavities, two hollow cavities Symmetrically arranged; the elastic yarn is a spandex core-spun yarn, which is spun with spandex yarn as the yarn core and wrapped with short fibers. The core filament of the spandex core-spun yarn is surrounded by the outer fiber, and the two are closely combined, and the core filament and the peripheral fiber have the same twist. It has three notable features: first, it has the same feel and appearance as cotton, wool, polyester-cotton and other yarns, and the outsourcing component composed of natural fibers has good hygroscopicity; second, it has good elasticity; third, the percentage of elasticity can be controlled within 20% or less. Compared with other elastic yarns, spandex core-spun yarn has a remarkable feature that the core yarn is not exposed when the yarn is stretched under tension. Therefore, the dyeing effect is good, and it is suitable for products of various colors including dark colors. Corespun yarns are less tenacious than other types of elastic yarns. Generally, the strength of a single yarn is only equivalent to 80% to 90% of the single yarn of the same specification outsourcing fiber. When the core-spun yarn is stretched by an external force, the outer fiber is the first to break, and the strength formed by the outer fiber is the strength of the core-spun yarn. Spandex yarn is a low-strength and high-elongation filament. It does not contribute to the strength of the yarn in the core-spun yarn, but destroys the cohesion between the fibers. Therefore, the higher the spandex content, the lower the strength of the corespun yarn.

Preferably, the thin warp yarns in the adjacent warp direction form a diamond shape.

As a preference, the four arcs connected end to end are composed of four alternately arranged outer arcs and inner concave arcs, the two outer arcs are arranged symmetrically to each other, and the two inner concave arcs are arranged symmetrically to each other . The above structure reduces the weight of the fabric and makes it more comfortable to wear, and the arc part forms an airflow channel, which acts as an air guide, increases ventilation, and has a good moisture absorption and perspiration effect. It has certain elasticity and toughness.

Preferably, the hollow cavities are circular and are respectively located on one side of the outer circular arc. The product reduces the weight of the yarn, and has a certain degree of elasticity, making the fabric more comfortable to wear; moreover, an airflow channel is formed in it, which acts as a guide for air, increases ventilation, has good moisture absorption and perspiration effects, and has a good There is more air content between the fibers, so the warmth retention of the fabric can be greatly improved, and the bulkiness of the finished fabric is 15% to 20% larger than that of ordinary fabrics.

Preferably, the monofilament fineness of said nylon monofilament is 0.6-1.3 dtex.

Preferably, the specification of the spandex yarn is one of 22.2dtex, 44.4dtex, 77.7dtex and 154dtex.

Preferably, the short fibers are one or more of cotton type, wool type and polyester type, with a length of 35-150 mm.

Compared with the prior art, this product has the following advantages: the product has better elasticity, when the elastic fabric is stretched under force, at the initial stage, the warp yarns are gradually straightened from the relaxed spiral state, and the load is gradually reduced to Large; the thick weft yarn used reduces the weight of the yarn, and has a certain degree of elasticity, which makes the fabric more comfortable to wear; and an airflow channel is formed in it, which acts as a guide for air, increases ventilation, and has a good moisture absorption and perspiration effect. And it has better bulkiness, and there is more air content between the fibers, so the warmth retention of the fabric can be greatly improved, and the bulkiness of the fabricated fabric is 15% to 20% greater than that of ordinary fabrics; and the use of The environmentally friendly bamboo fiber further improves the air permeability and elasticity of this product, and also has a certain antibacterial function.
