Slub yarn and production method thereof

Abstract

According to the slub yarn and the production method thereof, the style of a cloth cover made of the slub yarn can be effectively controlled by controlling the length of slubs and the distance between every two adjacent slubs, and meanwhile the style of the cloth cover made of the slub yarn can be effectively controlled by further controlling the speed and the temperature of a first roller and controlling the speed and the temperature of a second roller. By controlling the speed difference of the first roller and the second roller and controlling the temperature of the first roller and the temperature of the second roller, the optimal production process conditions of the slub yarn can be rapidly obtained, the cost is low, the method can be suitable for development and production of all the slub yarn, meanwhile, a cloth cover made of the produced slub yarn is not in a regular and neat style any more, and the production efficiency is improved. The method has regularity and randomness, the styles are more diversified, and the inaccuracy of making a sample by judging the styles with naked eyes is avoided.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber production, and in particular relates to a slub yarn and a production method thereof. Background technique [0002] Slubs were originally a common defect in textile production. During the spinning process, the yarn will have uneven fineness locally, forming protrusions similar to slubs, resulting in slub defects. Weavers found that when the bamboo-like protrusions are evenly distributed on the surface of the fabric, a special texture can be formed on the surface of the fabric to meet the aesthetic needs of some people. With the change of the trend of the times and the rapid changes of chemical fiber products, the development and derivation of differentiated fibers has already taken the leading position, and the development of new products must not only closely meet the style needs of users, but also take into account cost optimization. At present, the chemical fiber market The demand for s...

With the change of the trend of the times and the rapid changes of chemical fiber products, the development and derivation of differentiated fibers has already taken the leading position, and the development of new products must not only closely meet the style needs of users, but also take into account cost optimization. At present, the chemical fiber market The demand for slub yarn products is increasing, and the uniform and single slub yarn fabric style has been difficult to meet the demand, and the pursuit of slub yarn styles is gradually showing a trend of diversification.

The grooved roll method has been used to develop slub yarns all the time, and the rolls are not used after the grooved proofing is completed. At the same time, if it is different slub yarns, it is necessary to configure a grooved roll for each slub yarn, and each The cost of grooving rollers needs tens of thousands of yuan, the production cost is too high, and the produced products have too uniform layers of slub effect and a single variety, which is difficult to meet market demand
