How to reduce the pattern deformation of printed fabric?

Because of the characteristics of knitted fabric, the operation in the printing process is certainly different from that in the printing process of woven fabric. Reasonable and correct printing operation is the key to ensure and improve the quality and output of knitwear printing.

Sewing in textiles

In order to prevent skew defect of woven fabric, the most effective way is to tear the seam. Knitted fabric and woven fabric structure is different, it is impossible to take the operation of tear head seam head.

Knitted fabric in order to prevent the deviation caused by improper sewing head, the work to be done before the sewing head is: to see the fabric pattern, if necessary, the two cloth head along the cloth pattern. To distinguish the positive and negative sides of the fabric, so that the front is facing the front, the cut head along the edge of the cloth, then the seam head, and do the seam head to be firm and straight.

Section size and seam edge in textile

Woven fabrics produced by the textile mill to the embryo are flat width, so in the printing and dyeing production process without cutting and seam; But knitted fabric is different, it is produced by the knitting mill to the embryo is more cylindrical.

In the production process of knitted fabrics, some processing processes need to be carried out in open width, such as tensioning, printing, evaporation and so on. Some processing procedures also require the fabric cylinder, such as knitting fabric pretreatment, dyeing, post-printing flat washing, etc., to reduce and prevent knitting fabric yarn damage caused by loose crimping, and the edge is not easy to hold.

Therefore, with the needs of knitting production and processing, the cylindrical knitting fabric should be dissected into flat width. And sometimes the flat knitted fabric or seam into a cylinder, so that the smooth production. Knitting is done on a loom.

Pulp edge and cut edge in textile

Some specifications of knitted fabric are prone to crimping, which will seriously affect the quality of knitted fabric printing products and the smooth production of printing. Want to catch the pulp edge of knitted fabric for this, cut edge, basically be aimed at those in the production process easy to produce the knitted fabric that roll edge character. Woven fabrics also have the situation of edge rolling, such as cotton yarn card, cotton-ammonia elastic fabric in the wet and hot conditions of strong alkali, it is easier to have the situation of edge rolling, generally by improving the fabric edge, predetermined shape and clamping measures can be solved.

The above method is not effective in the production process of knitting fabric, and it is necessary to adopt the method of pulp edge and cutting a small amount of useless edge outside the pulp edge to ensure uniform fabric width and meet the needs of printing production. Insoluble slurry is generally used for slurry edge. The width of the slurry edge is about LCM, and the hardness of the slurry edge should be moderate. Excellent sizing is too thick, will make the edge and cloth thickness difference, affect the contact surface of the flower net and cloth so that the color of the printing is not uniform. Hardness can be mastered by knitting fabric on the rotary screen printing machine, not too thick.
