When we buy the products of waterproof PVC fabric tarpaulin manufacturers, it is required that the waterproof degree of the outer tent must be high and the air permeability of the inner tent must be good. What are the requirements in the sewing process of PVC tent fabric?
First of all, pay attention to the fact that the stitches of the pressing rope cloth should be double, and the distance between the two stitches close to the pressing rope should not be less than 45mm. The middle of the pressing rope cloth should be properly arched to facilitate the pressing rope to pass through, and the stitches at the starting and stopping points should not be less than 50mm. Then, the tarpaulin should be sewn straight, free of stitches, broken lines, and floating lines, and the stitches at the starting and stopping points should not be less than 3 stitches. Thirdly, three rope-wearing cloths should be evenly welded on each reinforcing rib, and the middle of the rope-wearing cloths should be properly arched to facilitate the waist rope to pass through. Another point is that the reinforcement angle should be flat and obedient to the cloth surface, and should not be bulging and wrinkled.
We must select qualified waterproof PVC fabric tarpaulin products to use. When goods are not covered, we should pay attention to drying the tarpaulin and keep it as dry as possible.
