Why does the feed color printing bags occur during the production process?

Feed color printing bag is a common packaging material, which is widely used in agriculture, chemistry, construction, trade and other fields.

During the production process, broken paths are one of the common problems.

Broken diameter refers to the phenomenon of the yarn in the fabric in the middle or weir direction.

The broken diameter will affect the quality and service life of the woven bag.

This article will analyze the reasons and solutions of the phenomenon of disconnecting diameter in color printing and woven bags from various aspects such as production technology, material selection, machine maintenance.

1. Production process

The production process of color printing woven bags is divided into three steps: woven, printing, and bag making.

During the shuttle process, broken yarn is one of the common problems.

Broken yarn can cause problems such as the fabric ball, shrinking, deformation, etc., affecting the intensity and peace of the woven bag.

1. Common causes of broken yarn include:

(1) Poor yarn quality. Select the yarn that does not meet the standards, fiber breaks, more impurities, and are prone to broken gauze phenomena.

(2) Improper maintenance of the machine. The problems such as bending hooks, broken hooks, and shuttle damage will also lead to broken gauze phenomenon.

(3) Improper machine adjustment. Improper adjustment of the machine, such as too much tension, improperly adjusted twisted adjustment, etc., can also lead to broken gauze phenomenon.

2. Solution:

(1) Select the yarn of excellent quality. The supplier is required to issue a quality test report that meets national standards.

(2) Regularly maintain and repair machines to ensure that the machine runs normally.

(3) Reasonable machine adjustment and debugging. In accordance with the production process and production requirements, adjust the tension, twisted, weaving speed of the weaving machine.

2. Material selection

Paper materials such as color printed woven bags usually use plastic materials such as polypropylene (PP).

The quality of the material has a vital impact on the quality and service life of color printing and weaving bags.

1. Common materials include:

(1) Poor material quality. The quality of the selected materials does not meet the standards, and it is prone to cracking, degradation, and break.

(2) The material batches are different. The material batches are different, and there may be differences in production technology and quality control, which will cause inconsistency between the intensity and peace of the woven bags.
