Description

Technical Field

[0001] The invention relates to the field of fabrics, and in particular to a new synthetic fiber bamboo-joint luminous composite sports fabric and a preparation method thereof. Background Art

[0002] In terms of raw materials, the surface fabric uses 100% 75D / 24F new synthetic fiber. This yarn has the characteristic of quickly producing bamboo knot effect when heated. At the same time, it is combined with a weft knitting 34"*28G single-sided open-width machine to weave the fabric; the base fabric layer is preferably made of polyurethane luminous film, which has good elasticity, high lightness, and certain moisture permeability and waterproof properties. In terms of technology, the dyeing and finishing of new synthetic fiber is basically the same as that of ordinary synthetic fiber, but because new synthetic fiber has special silk-forming characteristics and differentiated thermal properties, we are required to design the best processing conditions to give full play to its characteristics without damaging its original style. Therefore, the surface fabric is finished with a refining and finished product finalization process, and a moisture absorption and perspiration agent is added when the fabric is put into the cylinder for refining. In terms of performance, this fabric feels soft and has hygroscopicity, wear resistance, light resistance, sweat resistance and water washing resistance. Summary of the invention

[0003] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a new synthetic fiber bamboo luminous composite sports fabric and a preparation method thereof, wherein the preparation method mainly comprises the following steps:

[0004] S1 Blank preparation: Place the new synthetic yarn on a 34"*28G single-sided open-width machine and weave the fabric using weft knitting single-sided tissue to obtain the grey fabric.

[0005] Preferably, the new synthetic fiber in step S1 is 75D / 24F new synthetic fiber.

[0006] Improving the configuration of the surface and base fabrics and the weaving process of the fabric is a method to improve the moisture absorption and quick-drying performance of the fabric. The present invention preferably uses new synthetic fiber yarns and weaves them with weft-knitted single-sided tissues to maintain the elasticity and softness of the fabric. It can not only conduct moisture in a unidirectional manner to ensure that the skin-contacting surface is dry after sweating, but also has a good warming effect. The moisture conduction and perspiration process of the fabric includes wetting, moisture absorption, diffusion, and evaporation. The capillary effect of the fabric is used to quickly transfer the sweat on the body surface to the surface of the fabric through absorption, transfer, diffusion, etc., and then evaporate.

[0007] New synthetic fiber is a yarn blended from artificial fiber and natural fiber, which has the characteristics of high texture, high comfort and high elasticity. As a soft plastic luminous film, polyurethane luminous film has the properties of self-light absorption and self-luminescence, and its excellent properties such as flexibility and low-temperature flexibility make it widely used in composite materials. Through this innovative configuration of the surface and base fabrics, the fabric can be made soft, moisture-absorbent, wear-resistant and elastic. At the same time, the surface fabric is woven with a weft-knitted single-sided structure to improve the breathability and comfort of the fabric, making the fabric more suitable for occasions such as clothing that require comfort.

[0008] Preferably, a method for preparing a new synthetic fiber bamboo luminous composite sports fabric further comprises the following steps:

[0009] S2 dyeing: dyeing the grey cloth obtained in step S1, and adding a high-efficiency degreasing agent CPA, a polyester water-absorbing quick-drying agent and citric acid to obtain a dyed grey cloth;

[0010] S3 shaping: shaping the dyed grey fabric obtained in step S2 in a flat, shrunken and stretched state at a speed of 30 m / min and a roller pressure of 4 kg, and adding a polyester water-absorbing quick-drying agent and citric acid to obtain a shaped grey fabric;

[0011] S4 bonding: bonding the shaped grey cloth obtained in step S3 to the polyurethane luminous film by a hot melt adhesive bonding machine, and then rolling and placing in a constant temperature room for more than 24 hours. After testing and quality inspection, the new synthetic fiber bamboo luminous composite sports fabric is obtained.

[0012] Preferably, the dyeing process parameters of step S2 are: main pump speed 750r / min, cloth wheel speed 550r / min.

[0013] Preferably, the shaping process parameters of step S3 are: air volume 30 / 35Hz, cloth feeding wheel 3%, overfeeding cloth wheel 10.5%, upper pin wheel left and right 11%, and balance tension 2kg. Among the 10 ovens used, the oven temperatures of sections 1-3 and 10 are 150°C, and the oven temperature of sections 4-9 is 160°C.

[0014] Preferably, the bonding process parameters of step S4 are: temperature 26°C, relative humidity 63%, circulating water temperature 30°C, carving wheel gap -0.3mm, bonding wheel gap 0mm, main machine speed 15m / min, actual glue temperature 85°C.

[0015] Preferably, the dosage of the auxiliary agent in step S2 is 0.7 g / l of high-efficiency degreasing agent CPA, 0.5 g / l of polyester water-absorbing and quick-drying agent NICEPOLE PR-913, and 0.1 g / l of citric acid.

[0016] Preferably, the dosage of the auxiliary agent in step S3 is 1.5 g / l of polyester water-absorbing and quick-drying agent NICEPOLE PR-913 and 0.1 g / l of citric acid.

[0017] In addition, optimizing the dyeing and finishing process of the fabric can further improve the comprehensive performance of the fabric, such as moisture absorption and perspiration removal, wear resistance and water washing resistance. The present invention adopts a new configuration of the surface and base fabric and a weft knitting single-sided weaving process, and by adding specific auxiliaries during the dyeing and finishing process, the moisture absorption and quick drying, wear resistance and water washing resistance of the fabric are improved.

[0018] The present invention also provides a new synthetic fiber bamboo-joint luminous composite sports fabric, which is prepared by the above method.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The fabric of the present invention has the functions of moisture absorption and quick drying, night warning, and luminous energy to a certain extent solves many inconveniences caused by dark environment, improves sports safety, and can be applied to the field of night running clothes.

[0021] 2. The present invention adopts a unique configuration of the surface and base fabrics, weft-knitted single-sided tissue weaving and dyeing and finishing processes. The prepared fabric has a natural and delicate surface morphology, comfortable touch and permeability, and good ductility, making it more comfortable to wear. The skin-contacting surface always remains dry after sweating, and at the same time has a good warming effect, which is particularly suitable for wearing in autumn and winter.
