1. F silk, also known as segmented silk

F silk (segment spot silk) is horizontally striped silk, which refers to the stripes with obvious color difference in the dyed garter of the same sample. The analysis of the drawn silk strips found that the network nodes are normally and evenly distributed, and the silk strips have intermittent deep color absorption sections, and the dark sections have different lengths, indicating that the unfavorable factors vary, such as intermittent dark stripes appearing on the fabric.

2. K wire, also known as crimped wire

K wire is a transparent wire. Its surface is shiny, which is more transparent and brighter than normal wire. Generally, it is caused by insufficient deformation or insufficient untwisting during the false-twist texturing process. Missing inspection of K wire will cause obvious dark stripes on the fabric surface, and the fabric is likely to be scrapped directly, and the loss will be large.

3. D silk (deep silk) has regular and deep color absorption

D silk is a deep silk, which is obviously darker than normal silk. Draw out the dark garter wire and analyze it. Compared with the normal garter wire, there is no obvious difference in appearance of the wire except that the absorption color is obviously deeper than that of the normal wire. It was found that after dyeing, the back-end fabric would appear regular and obvious dark stripes, which caused defects in the fabric and could not be used normally.

4. L silk, (light silk) has regular light absorption

L silk is light silk, it is not easy to be colored, and the color absorption is obviously lighter than normal silk. The light-colored thread was drawn out for analysis, and compared with the normal thread, there was no obvious difference in appearance of the thread except that the color absorption was significantly lighter than that of the normal thread. Therefore, the missed L wire is difficult to be found in the downstream weaving process, and the downstream fabric will appear regular and obvious light-colored stripes after dyeing, which will cause defects in the fabric and cannot be used normally.
