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...
