Knitted fabric defect analysis_China Fabric Factory

After entering the autumn and winter seasons, most of the clothes everyone wears are knitted, such as various sweaters or knitted coats. Clothes made of wool are inherently warm and light-weight. They are fabrics It is incomparable. In addition, even if the knitted fabric is heavy, it will not feel bulky when worn on the body, and it is comfortable and light to wear. Knitted fabrics are very popular in winter, but this kind of fabric is very difficult to produce when it is produced. Various problems are prone to occur, so let’s talk about the defect analysis of knitted fabrics.

Analysis of defects in knitted fabrics
For example, during the knitting process, if the wool yarn is not hooked, there will be thread breakage on the fabric surface. A small vertical stripe hole appears. At this time, it is necessary to analyze whether it is the needle or the poor position of the yarn feeder. If it is the needle, it is mostly because the needle latch length is different or the needle size is different. All you need to do is to change the needle. Generally, the problem will be solved after changing to the same needle. If the position of the yarn feeder is too high or too low, needle leakage will also occur. In this case, it is relatively simple to adjust the position.

Yarn problems
In addition, when we analyze knitted fabric defects, not all problems are caused by machine failures. Sometimes the yarn itself If there are quality problems, it will also affect the finished product. For example, during the crocheting process, the fabric comes out with continuous small pits or the yarn is messy. At this time, you can check whether the yarn is uneven or not. The thicker yarn among the strands of yarn cannot come out. If the yarn position deviates from the yarn position, this phenomenon of scattered needles will appear. In this case, the thicker yarn can only be pulled up manually. If the material comes out If it still doesn’t work, you should consider changing the yarn to solve the problem.
