Method for preparing compact spun slub high count yarns

Abstract

The invention provides a method for preparing compact spun slub high count yarns and the compact spun slub high count yarns prepared thereby. A low count yarn gap sheet control and high count primary drawing matched mode is adopted in a spinning process in a method for preparing blended far infrared fibers; and pressure of 10 to 14kg is applied to a drawing zone of a spinning frame, a chemical fiber leather roller is used, Vickers hardness is 70 to 83 degrees, and special long stapled cotton in a certain ratio is selected as a raw material. The method overcomes the defect that the conventional high count slub yarns have low strength and a large number of long hairs, the wearability of a product is improved through technological innovation, the slub yarns are united in a compact bundling device to make a fabric surface have smooth and clear appearance, and the third dimension of a fabric is increased.

Description

technical field [0001] The invention relates to the technical field of textile fiber manufacturing, in particular to a method for manufacturing compactly spun slub high-count yarns and products made of the fibers. Background technique [0002] Slub yarn is a new type of yarn that has emerged in recent years. It is widely used in the production of various fabrics. It conforms to the current fashion trend and is widely popular. There are many varieties of slub yarn and a wide range of applications. Because the slub yarn fabric has a strong three-dimensional effect after finishing, it has a variety of fancy effects, and is loved by consumers. Generally speaking, according to the spinning form of slub yarn: there are air spinning slubs and ring spun slubs; according to the length of slubs: there are long bamboo, medium bamboo, and short bamboo; according to the multiples of slubs: there are thick bamboos , medium bamboo, fine bamboo; and so on. [0003] The variety of slub ya...

Problems solved by technology

[0004]The existing slub yarn production method uses a single roving to be fed into the drafting zone, and through the slub yarn device, the rotation speed of the middle and back rollers is changed, thereby changing the roving The feeding amount of the slub yarn with varying thickness is output through the front roller. Concentrate on the details, and the twist at the thick joints is relatively weak, especially when producing products with long slubs or large multiples, it shows low yarn strength, large strength unevenness, and long hairiness, making it almost impossible to manufacture. Low production efficiency

Especially in the production of high-count slub yarn products, the frequent speed change of the front roller of the spinning frame causes the fibers in the twisting triangle area to be unstable and clustered, and the twisting is more likely to cause yarn breakage
