Description

Technical Field

[0001] The invention relates to the technical field of textile weaving, in particular to a process for preparing a mesh cloth with environmental protection and high elasticity. Background Art

[0002] In order to improve the wearing comfort, the footwear and clothing products currently on the market have certain requirements for the elasticity of the footwear and clothing products. In the prior art, in order to increase the elasticity of the footwear and clothing products, spandex yarn or composite fibers with spandex fibers are usually added during the weaving process of the footwear and clothing fabrics.

[0003] Spandex is an elastic fiber, scientifically known as polyurethane fiber (PU). It is highly elastic and can be stretched 6 to 7 times, but it can quickly return to its original state as the tension disappears. Its molecular structure is a chain-like, soft and extensible polyurethane, which is connected with hard segments to enhance its properties. Elastic fibers are divided into two categories: one is polyester chain; the other is polyether chain. Polyester elastic fibers have strong antioxidant and oil resistance; polyether elastic fibers have good mildew resistance and detergent resistance.

[0004] However, spandex also has its physical defects. For example, spandex is too elastic, which makes it feel too tight when worn and the fabric has poor air permeability. Due to the molecular structure of spandex, it is easy to age. After long-term use, its elasticity decreases and its fatigue resistance is poor. Spandex is a petroleum derivative, and its production process has a relatively high dependence on petrochemical resources, energy consumption and greenhouse gas emissions. The color fastness of spandex-containing fabrics is poor, and the fabrics dyed with spandex have serious color transfer and overflow (when spandex is dyed, the color fastness after coloring, especially the color fastness to staining, is poor, which will produce color transfer). If the spandex is affected by the dye after reduction water washing, there will always be dye residue, and the color of the fabric will be different each time. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a process for preparing an environmentally friendly and highly elastic mesh that can increase the elasticity of the mesh during preparation and is convenient for use in footwear and clothing products.

[0006] The present invention is realized by the following method: a process for preparing an environmentally friendly and highly elastic mesh, the process comprising the following steps:

[0007] Step S1, when in use, placing a wire delivery frame at the left and right ends of the circular loom, and placing a cheese yarn on the wire delivery frame;

[0008] Step S2, guiding the silk thread out through the guide member, and conveying the silk thread to the feed inlet of the circular loom for weaving;

[0009] Step S3, the weight ratio of the silk thread is 60%-64% of polyester low-elastic, 6%-10% of spandex, and 30% of monofilament. The threading method of the polyester low-elastic is 2-through and 2-empty, while the threading method of the spandex and monofilament is full-through, so that a mesh with high elasticity can be woven through a circular loom.

[0010] Furthermore, the wire outlet frame includes a supporting base plate, movable wheels are arranged around the lower surface of the supporting base plate, support rods are arranged at left and right ends of the upper surface of the supporting base plate, a fixing plate is arranged on the support rod, a strip guide opening is opened on the support rod, a placing plate is connected to the strip guide opening by bolts, a plurality of placing columns for placing cheese yarn are equidistantly arranged on the placing plate and the supporting base plate, the guide member includes a first connecting rod, the first connecting rod is arranged at both the upper and rear ends of the left side face of the placing plate, a second connecting rod is arranged between the first connecting rods at the front and rear ends, a plurality of first guide wheels are equidistantly arranged on the second connecting rod, an L-shaped supporting plate is arranged at both the front and rear ends of the left end of the upper surface of the fixing plate, a third connecting rod is arranged between the L-shaped supporting plates at the front and rear ends, and a plurality of second guide wheels are equidistantly arranged on the third connecting rod.

[0011] Furthermore, the yarn is warped according to the tension requirements of the process, and the cheese yarn is wound into warp beams in parallel under certain warping process conditions according to the number of yarns required by the circular weaving process and the length required for production, for use in the circular loom.

[0012] Furthermore, the step S3 is further specified as follows: the number of warping strands of the polyester low-elastic yarn is 880, and the number of warping strands of the spandex and monofilament yarn are both 440.

[0013] The beneficial effects of the present invention are as follows: the polyester layer can effectively improve the strength, elasticity, heat resistance, wear resistance, corrosion resistance and light resistance of the high-elastic mesh cloth, can effectively extend the service life of the high-elastic mesh cloth, and reduce the use cost of the high-elastic mesh cloth. The use of polyester low-elasticity can increase the elasticity of the mesh cloth, making the application range of the mesh cloth wider. At the same time, since polyester low-elasticity, spandex and monofilament are interwoven with each other, the elasticity of the mesh cloth is increased; the flatness performance of the high-elasticity mesh cloth after production is improved, and the sales difficulty of the enterprise is reduced.
