Problems solved by technology

However, because the spinning speed is too fast, and the existing production equipment needs to be modified and debugged due to the variable speed of the metering pump or the transformation of the heat roller, the production process is complicated and difficult to control. The slub of nylon 6 filament with slub effect The length and slub spacing are relatively large, and the reproducibility of characteristic parameters such as slub length, slub multiple, and slub spacing is poor. It is difficult to predict the three-dimensional effect and dyeing difference of fabrics woven with nylon 6 filaments with slub effects. control

Abstract

The invention discloses a nylon 6 filament with slub effect and a production method thereof, which belong to the technical field of chemical fibers. The production method comprises the following steps: passing the nylon 6 pre-oriented yarn through a raw silk rack, a shredder, and a second yarn successively. The first roller, the yarn guide, and then pass through the hot box, the cooling plate, the false twister, the second roller, the third roller, the thread detector, the oiling device, and the winding device to produce nylon 6 filaments with slub effect . The production method provided by the present invention does not need to undergo equipment modification and debugging, and only through the adjustment of the texturizing process, nylon 6 filaments with slub effects can be obtained. The nylon 6 filaments with slub effects prepared by this method It presents different coarse and detailed distributions, and the length of the bamboo, the multiple of the bamboo and the spacing of the bamboo are changeable and controllable.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to a nylon 6 filament with slub effect and a production method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for fibers and fabrics are gradually increasing. Nylon 6 is a good variety among synthetic fiber fabrics because of its hygroscopicity. The woven fabric is skin-friendly and soft, the skin feels mild, the texture is flexible, and the cotton-like and silk-like effects are strong. It is more and more favored by people. With the improvement of people's quality of life, people's requirements for the differentiation and high-end of nylon 6 are also getting higher and higher. [0003] Slub yarn is a kind of fancy yarn, which has the appearance of uneven thickness, and its fabric has a warm and heavy or smooth and elegant style, which can be used for heavy winter fabrics and light summer fabrics, ...
