Adjustment of technical parameters: After the dyeing and finishing technology is determined, parameters such as bath ratio time can be adjusted appropriately, for example, the bath ratio can be appropriately increased or the technical curve can be improved to shorten the time.
Dyeing and finishing process Singeing: Singeing is a great way to reduce hairiness and reduce pilling. Weaving process The organizational structure of knitted fabrics has a great influence on pilling, and the tight organization is less prone to pilling than the loose organization. In order to reduce the hairiness, the textile mill rationally mixes cotton, optimizes the process, adopts advanced textile technology according to its own conditions, and tries to control the occurrence of hairiness within the scope of its ability. So how can we reduce the pilling of our fabrics? Spinning process During the spinning process, the fibers in the twisting triangle area undergo repeated internal and external transfer due to uneven force, causing the head end, tail end or middle part of most fibers to protrude from the yarn body, forming hairiness. In the process of wearing and using fabrics, different degrees of pilling will occur. Knowledge Sharing: Measures to Reduce Pilling From the test results, the stain level of the soaking method is much more serious than that of the washing method. The samples tested by the two methods are evaluated by Gray scale for color staining. After the test is completed, after rinsing the test, it is necessary to absorb excess water with filter paper and hang it to dry. In terms of test time, the washing method requires 30 minutes and the soaking method is 4H. The test temperature of the washing method is 3☌ higher than that of the soaking method. Put the loaded sample into the Precision Drying Oven, the temperature is 37 degrees, for 4 hours, take out the combined sample, and rinse it with running water until it is clean. Put the sample and test solution into the container, press and move from time to time to completely soak the sample, take out the sample and place it on the Perspiration Tester, and apply a pressure of 5000g. Take out the sample and rinse it with running water until it is clean. Put the container into the machine, set the temperature to 40 degrees, and test it for 30 minutes. Put the sample and test solution into the container 2. Test Instruments The washing method: Wash Colour Fastness Tester The soaking method: Precision Drying Oven Operating procedure The washing method 1. The sampling and soap solution configuration of the two methods are the same, the only difference is the test equipment and operating procedures. Add detergent according to the sample weight. Cut a piece of dark and light-colored fabrics, 4×10cm, and sew them along the short side to form a combined sample. After cleaning and drying, the staining of the light-colored sample is evaluated with Gray scale for color staining or an instrument. The soaking method The sample is placed in the specified washing solution, and after treatment, it is placed between two flat plates with a specified pressure in the test device.
The washing method The sample is placed in the specified washing solution, mechanically stirred according to the specified bath ratio, time and temperature, then washed and dried, and the staining of the light-colored sample is evaluated with a staining gray card or an instrument. Test methods for testing the interdyeing of textiles by splicing, namely the washing method and the soaking method.

In response to this phenomenon, there is a professional name in textiles: splicing and mutual dyeing. This is due to the mixed washing of dark and light-colored clothes, the fading of dark-colored clothes and dyeing on light-colored clothes, resulting in staining of light-colored clothes, or the mutual staining of dark and light colors on a piece of clothing after washing.
