If the weft needle is damaged, replace it or beat it with gauze; If the steel buckle is damaged, hit it with gauze or replace the steel buckle; The coir filament piece is damaged or the shutdown piece is damaged. Replace it with a new one. Causes of poor needle edge: uneven weft yarn thickness; The knitting needle is not properly laid, too long or too short; The pan head moves abnormally, sometimes tight, sometimes loose; The weft wheel is not round enough and deformed; The fixing pin of knitting needle is worn; Precautions: change another weft yarn; The knitting needle is longer or shorter according to the thickness of the ribbon.

The basic process flow of knitting is: bleaching and dyeing - weft rolling - weaving - off machine cutting - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality. In 1980, SD-81A and B rubber ingot belts were developed, which are soft, light, thin, firm, with small elongation, small impact force, short and flat joints. At the beginning of 1990, the trial production of car seat belts for Santana cars was successful. After more than two years of research and trial production, the product quality reached QC49-92 and TL-VW470 standards.

Clamp Aramid tape Immerse the cloth with distilled water and completely wet it. Then squeeze the water out of the extruder, and then clamp these colored cloth wrapped with selvedge webbing into the plexiglass sheet, put it into the sample holder, and lock the sample holder. This rack is placed in a high and low temperature box at a certain temperature, and after reaching the specified time. Take out the sample and hang the colored cloth.

But it also has an advantage, because it will not affect the original texture of the fabric, so it is more suitable for large-scale printing patterns. It is characterized by soft handle and bright color~~But there is a big disadvantage of the slurry. The color of the slurry is lighter than the cloth color~~If the cloth color is darker, the slurry can not cover at all.
