Embodiment

[0018] The production method of the rayon knitted composite fabric of the present embodiment comprises the following production steps:

[0019] 1) Raw material selection, choose 13.3tex artificial viscose yarn and 14.5tex combed cotton yarn as raw materials;

[0020] 2) Weaving, using 4-needle track single-jersey circular knitting machine for interweaving, 18 needles / 2.54cm;

[0021] 3) Wash with water, heat the water to 40°C, put gray cloth and cleaning agent, wash away the stains on the cloth surface, and then dry at low temperature;

[0022] 4) High-temperature shaping, the gray cloth after drying is expanded and shaped by a combined heat finishing machine, the temperature is 190-220 °C, the steam pressure is 2.5-3.5 kg / cm2, and the shaped gray cloth is naturally cooled for 24 hours .

[0023] 5) Cloth compounding, take thermoplastic polyurethane TPU film to apply glue, preheat, and then carry out hot pressing with the obtained cloth, and get the finished product after co...

Abstract

The invention discloses a producing method of rayon knitting composite fabric. Artificial viscose rayon with a size of 13.3 tex and combed cotton yarn with a size of 14.5 tex are adopted as raw materials. The method includes: interweaving by adopting a single-jersey 4-track circular machine with a machine gauge of 18 needle/2.54 cm, heating water to 40 DEG C, adding grey fabric and a cleansing agent, washing to remove dirt on the surfaces of the fabric, drying at a low temperature, stentering and setting the dried grey fabric by a combined heat finishing machine at a temperature of 190-220 DEG C and under a steam pressure of 2.5-3.5 kg/cm<2>, naturally cooling the set grey fabric for 24 h, coating thermoplastic polyurethane (TPU) film with glue, preheating the film, subjecting the film and the obtained fabric to thermocompression bonding, and cooling to obtain a finished product. The method is simple in processing process and low in producing cost. The fabric has hygroscopicity similar to that of natural fiber and is comfortable to wear. The fabric has handfeel and appearance like silk, and is bright and clean. In addition, the fabric has good waterproofness, good moisture penetrability, and good antibacterial and bacteriostatic performances.

Description

[0001] technical field [0002] The invention belongs to the technical field of fabrics, and in particular relates to a method for producing rayon knitted composite fabrics. [0003] Background technique [0004] Viscose rayon is a medium-heavy fiber with good strength and abrasion resistance. It has hydrophilic properties (11% moisture regain). This fiber can be dry cleaned and washed with good care. Pilling phenomenon, reasonable price. The performance of viscose rayon is similar to that of cotton, and its hygroscopicity is better than that of cotton, but the strength and dimensional stability of viscose silk fabrics are poor. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems existing in the prior art field, the purpose of the present invention is to provide a production method of rayon knitted composite fabric, which has simple processing technology, low production cost, short process, and the cloth has the hygros...
