Yarn woven into fabric often experiences horizontal stripes after dyeing, resulting in significant losses that are hard to rectify, especially when the stripes are caused by raw material mixing issues. These issues often lead to a large number of stripes and substantial losses. How can the mixing of various fibers be properly managed?
Spinning factors caused by the warp on the canvasFactors contributing to cross grain on fabric surfaces involve the entire textile dyeing process, with many reasons specifically related to the spinning process. These include aspects such as spinning materials, techniques, environment, operation, and machinery, covering all stages and processes, such as differences in cotton maturity, uneven weight, uneven fiber blending, inadequate innovation, uneven twist, and differences in fluff, etc. According to the meeting schedule, this section mainly introduces how to effectively blend various fibers to prevent the occurrence of cross grain on fabric surfaces.Analysis of Two Processing Technologies for Blended FibersTwo processing methods for mixed fibersMixed fibers are generally categorized into two types: open mix and carded mix.Analysis of the Advantages and Disadvantages of Mixing BallsAdvantages: Packages of two or more fibers are directly sorted by weight ratio, simplifying the production process through mixing, rolling, carding, and blending stages. This method is convenient for scheduling. When a fiber has poor spinability, it can be mixed with other fibers in the cotton package for production, which can also improve its spinability.Flaws: Due to significant differences in fiber properties, moisture regain rates vary greatly, resulting in inconsistent tightness of packaged raw materials. This causes the disc dozer to pick up varying amounts of material, leading to uneven fiber blending. In other words, the blending ratio is unstable, which is prone to forming horizontal stripes in the fabric's dyeing.Analysis of the Pros and Cons of Mixed-Style ProductsAdvantages: Two or more fibers are processed individually in the opening and carding stages to form rovings, which are then blended in proportion during the combing process. When chemical fibers are blended with cotton, since cotton contains more impurities and short fibers and the chemical fibers are cleaner, it is generally more convenient to remove impurities and short fibers from the cotton by processing it separately through the opening and carding stages. The blending of涤棉 (polyester-cotton) often employs this method. The advantage of this approach is that the blending ratio is easy to control.Drawbacks: Processing two or more fibers separately during the opening and carding processes increases the production flow and complexity of management, making blending uneven and necessitating an increase in the number of roving units, often employing three-rouging processes. Fibers with poor spinnability can be challenging to handle during the opening and carding stages; labor and electricity costs also increase."High twist yarn, low twist yarn, untwisted yarn, high tenacity yarn,涡流纺yarn, reverse twist yarn, bamboo yarn, and other specialized yarn varieties.
