3, out of the vat, bake at 120-150℃ for 1-3 hours after dehydration

The key points of the process:

1. Liquid entrainment rate: 70% (according to the type of fiber)

2, bath temperature: about 60℃

3. Drying temperature: 120-150℃

2. Waterproof shoe material fabric

Here we take the example of flying shoe materials. Flying shoe materials are mostly used in sports shoe fabrics. Flying weaving is a special high-tech weaving technique.

2, baking

Bake separately on the baking machine 150℃×1-3 minutes (according to the type of fiber); fast baking on the setting machine 170℃×1 minute (according to the type of fiber)
