Woven bag manufacturers have strict marking requirements for the width design and feel of the woven bag during the production process. Thread breakage is a common fault encountered in the sewing of woven bags. Today, I will show you how to deal with the broken thread during the production of woven bags.

The quality of the suture is not up to the requirements, the machine is not adjusted properly, the thread passing parts have sharp edges, the operation method is problematic, the needle cooling is insufficient, etc., all will cause the thread to break. During the sewing process of the woven bag, the rotary hook rotates for two cycles every time the needle pierces the material, and completes the hooking and expansion of the upper thread loop in a week, and then runs idling. If the rotary hook hooks the upper thread every week, that is, the needle pierces the material once and spin If the hook thread is used twice, it will inevitably conflict with the retracting and unwinding of the upper thread, and the suture will be broken.

In order to ensure the quality of the woven bag, we can also add calcium masterbatch to the PP flat yarn material, which feels very broad, and less HDPE in the PP will make it softer. The woven bag factory produces a wide range of products and processes woven bags according to the needs and characteristics of users.
