What are the reasons for the easy cracking of non-woven bags

We often encounter that the newly purchased non-woven bag is easy to crack at the edge of the bag, even without too much force. Moreover, a non-woven bag with a slit is easier to crack. What is the reason why these non-woven bags are easy to crack, let's take a look together next. First of all, there is a problem with the non-woven bag factory workers who have changed the method of cutting hemming. Workers with wrong methods must pay attention to them in daily production. After a long time of correction, they will form a habit. This will naturally change. Under normal circumstances, the cutting position should be three millimeters higher than the mouth of the non-woven bag, so that the firmness of the mouth of the bag can be ensured without affecting the appearance. When we cut the hemming, we can't cut the part of the needle that is inverted. When turning the needle, the number of needles must be sufficient. It's equivalent to cutting off all the strong and firm back stitches we used before, so this problem occurs. Since we need to cut the hemming after we withdraw the stitch, if we cut it too flat and cut it to the same height as the bag mouth. However, there are some misunderstandings in the methods of some workers, thinking that the flatter and cleaner the hemming shears are, the better the appearance and quality. In fact, this is not the case. When we are producing non-woven bag edging, we need to withdraw the needle to strengthen the sturdiness of the bag mouth. In fact, the above reasons are not the non-woven fabrics nor the production process. The problem mainly lies in the methods of the sewing workers. The above is a summary of the detailed content of the reasons why non-woven bags are easy to crack.
