Methods to Improve the Mixed and Uneven Condition
The blending process ensures uniform mixing of long fiber segments, maintaining precise blending ratios, thus resulting in superior fabric surface effects. However, the blending process must have both good uniformity in the weight of the slivers and reasonable determination of the blending and spinning techniques to reduce uneven mixing.Improving the uniformity of yarn weight is the foundation for reducing yarn blending variability and achieving evenness.Enhance combing efficiency, facilitate the optimal transfer of fibers, and improve the cotton web structure.The carding process requires the use of card clothing to enhance the separation of fibers, improving the straightness and parallelism of the fibers and the clarity of the cotton web. Determine the appropriate speed ratio between the cylinder and the cylinder, maintain a higher cylinder speed, reduce the cylinder speed, and promote a good transfer of fibers from the cylinder needle face to the cylinder needle face, reducing the return of fibers from the cylinder and effectively reducing cotton lumps and improving the cotton web structure. Keep the spacing between the cylinder and the cover plate slightly smaller, control the staple weight slightly lighter, and maintain a tighter spacing between the cylinder and the roller, strengthening the carding and promoting the good transfer of fibers. Control the tension stretch ratio of the cotton web slightly smaller to prevent the cotton web from sagging.(2) Standardize process parameters across identical machines, regulate the timing and sequence of needle cleaning, reduce cotton shedding variations between machines, and decrease the weight inconsistency of the sliver between machines.Strictly control the process parameters affecting cotton shedding, such as the distance of the bottom entrance, lid speed, and the top opening distance of the front cover plate. When changing rolls, the stopper should use the diagonal overlap method. During the operation of starting and stopping the machine, remove a section of slightly lighter strips according to the operational specifications. When using the combing and carding unit, install an automatic leveler on the combing machine and conduct regular inspections and calibrations to fully utilize its function.(3) Implementing the Practice of Simplified Comb and Carding Line Quantitative ControlOur company has recently implemented a technical transformation from the open-end process to the simplified carding and combing process. Due to the lack of a mixing ring-type automatic tensioning device, there are fluctuations in the weight of the fiber staple during spinning, leading to an uneven weight distribution and affecting the quality of the fabric surface. On one hand, we continue to improve the pipeline design and adjust the electrical systems. On the other hand, we have also practiced a quality control technique that combines internal and external unevenness in the weight of the staple.1 set of simple carding and combing unit with 16 combing machines, variety: polyester"High twist, low twist, untwisted, high tenacity,涡流纺, anti-twist, and bamboo yarns, among other "specialized, refined, unique, and innovative" yarn varieties.
