Embodiment Construction
[0014] The technical solutions of the present invention will be further described below in conjunction with the embodiments.
[0015] The program adopts the following technical measures:
[0016] 1. The steaming temperature is 100-105°C, vacuumize for 2.3 hours, and cool in the pot for about 30 minutes.
[0017] 2. Warp-sizing joint process: increase the unwinding tension of the bobbin, especially the 24 yarns located on both sides of each yarn generation, and adjust the tension angle to the maximum to increase the friction to control the tension on both sides of each yarn belt. Reduce the chance of hemming of the yarn on both sides.
[0018] 3. At the same time, increase the coverage factor of the yarn in the sizing tank. Generally, the sizing coverage factor of the yarn in the variety is between 30 and 60%. When sizing this product, the coverage factor is about 70%, which can be very good. Solve the twisting phenomenon of yarn when parking and slowing down. This is diffic...
