What conditions should be met for tarpaulin repair and maintenance

Generally, when wholesale tarpaulins in the tarpaulin wholesale market, some merchants will remind sellers that if the tarpaulin is damaged, it needs to be repaired and repaired. Whether the repaired tarpaulin is suitable for use, then several conditions need to be met. 1. If double stitches are used, there should be a distance of 15mm to 20mm between the outer stitches and the periphery of the patch cloth, and the distance between the two stitches should be 10mm. 2. If the two-sided straight double-thread machine is used, the distance between the two stitches close to the pressing rope should not be less than 45mm, and the middle after the tarpaulin is sewn should be properly arched to facilitate the pressing rope to pass through and lift. The needle and needle stop should not be less than 50mm back. At the same time, it should be noted that waterproof glue should be painted on both sides at the eye of the machine repair needle. 3. Relevant water hoisting test should be carried out at the repaired place, and water seepage, smearing and water leakage are not allowed; and the middle of the rope-wearing cloth should be properly arched after repairing, so that it is convenient for the waist rope to pass through. 4. The tightness of the suture should be uniform and straight, and the needle size should be 14-18 stitches/100mm. At the same time, pay attention to not less than 3 stitches at the starting and ending points. The above are the conditions that need to be met after the tarpaulin is repaired.
