1. Knitted fabric will block the net when printing
Knitted fabric is a headache when printing because of the large number of grey fabrics. The main reason is that the pre-treatment process of knitted fabric and woven fabric is different. Knitted fabric does not do singeing and mercerizing treatment. It is easy to fluff when processing cloth, so this kind of phenomenon will appear when printing.
Solution: 1. The warehouse must strengthen the inspection of grey fabrics. For knitted fabrics with poor quality, the warehouse must notify customers in time, communicate with them to explain the reasons, and give solutions; 2. Adjust the knitted fabric process in time And increase the number of washing, try to reduce the hair to the minimum; 3. When the semi-finished product is shaped, increase the water flow of the rolling groove, and let the running water wash away a part of the hair.
2. There are more holes in the finished knitted fabric
Holes in the finished knitted fabric are mainly caused by the following reasons: holes in themselves; holes caused by mechanical damage; holes caused by man-made reasons.
Solutions: 1. Carefully inspect the grey fabrics with many neps, yarn breaks, or yarn counts, and notify the customer to deal with them in time; 2. Choose a smooth, high-performance machine cylinder to process knitted fabrics.
Third, the problem of gram weight in the production of knitted fabrics
Generally speaking, customers are more particular about the weight of finished knitted fabrics, which is also an important step for printing and dyeing enterprises to do well in the quality of knitted fabrics.
In order to ensure the gram weight of each batch of knitted fabrics, measures need to be taken: 1. Check the quality of the grey fabric. Generally, the gram weight of the incoming blank can meet the gram weight of the finished product, but if the gram weight of the semi-finished fabric does not reach the predetermined gram weight of the finished product Requirements, it is difficult for the finished product to meet the weight requirements; 2. Reasonable selection of machinery and equipment, process operations, and dyeing and chemical additives.
Fourth, the problem of anti-staining of knitted fabrics in washing
Since knitted fabric has not been mercerized, it is easier to stain during washing, so the requirements for anti-staining are also higher.
Therefore, it is necessary to: 1. The color of the steamed hair should be complete. If the steaming is not good, the color will fade after washing and the staining will be more severe; 2. The floating color should be washed clean. With less floating color, it is not easy to be stained during soaping; 3. Use a soaping agent with better anti-staining performance to avoid staining.
