1 Unwinding and sewing
The process of the flat-spreading machine of the equipment requires that the Tencel fiber is different from the ordinary regenerated cellulose fiber, and it is easy to produce creases, scratches, and other defects that are difficult to eliminate during the placement process. Therefore, the general weaving mills form parts in the form of rolling. Before the dyeing and finishing process, the unwinding must be carried out. At the same time, blank inspection and counting must be completed. The sewing head must be flat, straight, and uniform, and the front and back must be the same. At the same time, in order to avoid the weft caused by uneven cutting, the front must be Tear every head.
2 predetermined type
The technical requirements of the equipment setting machine must ensure that the stability of the width of the finished fabric of the twill stretch fabric and the requirement of the weft shrinkage rate must be predetermined before the dyeing and finishing process. The general temperature is 180°C, the speed is 35m/min, the scheduled type cannot be stopped halfway, the speed must be uniform, and the process conditions must be strictly controlled. If the temperature is too high or the speed is too slow, the elasticity of the finished fabric will be insufficient and the width will be too large. On the contrary, it will Causes the width of the gate to be too small and the elasticity to be too large.
3 pre-processing
Equipment cold-rolling and stacking process requires Tencel products to easily produce scratches, purlins, creases, etc. during the dyeing and finishing process, so it is not appropriate to use rope pre-treatment, and in the conditions of hot and humid alkali, spandex will lose its elasticity and Extensibility, therefore, Tencel cotton twill stretch fabrics are suitable for the cold-rolled stacking process under flat soda conditions.

After stacking the temperature and room temperature, the rolled fabric is wrapped and wrapped with plastic film.
4 Washed
The process of equipment washing machine requires the fabrics to be placed in the cold-rolled reactor for 12 hours. The slurry on the surface of the fabric has been transformed from the initial gel state to the sol state. The impurities on the fabric have also been expanded or decomposed and converted into washable substances. Under certain temperature conditions, the slurry and impurities on the surface of the fabric are washed away by washing with water, so that the desired whiteness and hairiness are obtained.
Washing process: the first 1-3 grid 90-95 °C hot water wash - steamer 98 °C showering - the first 4-5 grid 85-90 °C hot water - 6th grid 50 °C hot water - drying cloth.
5 Shaped rolling
The process requirements of the equipment setting machine must meet the requirement of alkali treatment in the post dyeing machine. In the process of rolling, it must be ensured that the fabric is not flat.
Process conditions:
Speed ​​40-50m/min
Temperature 140°C
The width of the door is slightly wider than the width of the door
