In the modern textile industry, warp knitting machine, as a common weaving equipment, is widely used in the textile industry and plays a vital role. The adjustment of shift time of warp knitting machine is one of the important links, which directly affects the quality and production efficiency of fabric. This article will give you a detailed introduction to the warp knitting machine shift time adjustment methods and skills, to help you easily become a "time master" in the knitting industry.
First, understand the importance of needle transfer time adjustment
The shift time in the warp knitting machine refers to the time of straightening the row of needles to weave, which determines the density, texture and uniformity of the fabric. The unreasonable needle transfer time will lead to the dislocation and defect of the fabric and affect the quality of the fabric. At the same time, the adjustment of needle transfer time can also affect the production efficiency, reasonable needle transfer time can improve the production efficiency, reduce energy consumption and cost.
Second, the method and skill of adjusting the needle transfer time
1. Select the appropriate needle transfer time according to the type and density of yarn
Different yarn types and densities have different requirements for needle transfer times, so it is necessary to understand the characteristics and requirements of the yarn used before adjusting the needle transfer time. Generally speaking, roving requires a longer shift time, while fine yarn requires a shorter shift time.
2. Pay attention to the texture and uniformity of the fabric
Good fabric texture and uniformity is one of the important indexes of warp knitting products. In order to ensure the texture and uniformity of the fabric, it is necessary to adjust the transfer time according to the actual situation. Moving the needle too long or too short will cause the texture of the fabric to be unclear or uneven, so it needs to be adjusted appropriately according to demand.
3. Observe the quality of the fabric
Observing the quality of the fabric is an important basis for judging whether the needle transfer time is reasonable. When adjusting the needle transfer time, it is necessary to pay close attention to the quality of the fabric, compare the quality difference of the fabric under different needle transfer time, and find the best needle transfer time.
4. Pay attention to the adjustment of weaving speed and process parameters
Needle transfer time is closely related to weaving speed and technological parameters. While adjusting the needle transfer time, it is also necessary to adjust the weaving speed and process parameters appropriately according to the actual production needs to achieve the best production results.
