How to maintain the stability of gram weight in the production of knitted fabric printing? In order to guarantee the weight of each batch of products, the following measures need to be taken:
First, the quality of the grey fabric should be checked. Generally, the weight of the blank can reach the weight requirement of the finished product. However, if the weight of the semi-finished fabric does not reach the predetermined requirement of the finished product weight, the finished product is difficult to meet the weight requirement. Therefore, the weight of the semi-finished product is very important, and it is generally required to predict the weight of the finished product when the semi-finished product is finalized;
Second, the fabric with spandex should be pre-prepared, which can stabilize the weight of the finished product;
The third is that for the products that can't be redone, the factory first analyzes the reasons by itself, tries to change the process operation, and tries to meet the customer's requirements as much as possible. The second is to inform the customer to negotiate settlement;
The fourth is the reasonable choice of machinery and equipment, process operation, dyeing chemicals. Because the inherent performance of the machine is not more than the weight requirement, the setting machine for knitting fabrics must be selected, or appropriately modified, and the temperature of the drying room is required to be stable, and the performance of circulating air blowing and super feeding is better.
According to the characteristics of the grey cloth, the development of a suitable process also plays an important role in ensuring the weight. For example, the pretreatment is to select as much as possible the additive with less weight loss on the fabric, and the best process is used to ensure the weight of the product. If conditions permit, the coating process should be considered as much as possible to achieve the purpose of stability and weight gain. Fifth, when the finished product is shaped, some additives can be added to increase the weight. For example, additives such as urea and water can make up for it. The problem of insufficient fabric weight.
