Preparation method and device of dual different-shrinkage combined filament yarn

The invention relates to a preparation method and device of dual different-shrinkage combined filament yarn. The device comprises a first spinning component, a second spinning component, a lower spinning reel, an upper spinning reel, a first hot roll, a second hot roll, a first redirector, a doubling machine, a netting device and a winding roll, and is characterized by also comprising a third hot roll, a fourth hot roll and a second redirector. The preparation method is characterized in that one part of yarn output by the second spinning component is input to the doubling machine through the first hot roll and the second hot roll; the other part of yarn output by the second spinning component is input to the doubling machine through the third hot roll, fourth hot roll and second redirector; and after the doubling machine merges all the input yarn, the yarn is processed by the netting device and the winding roll, thereby finally obtaining the dual different-shrinkage combined filament yarn. The looped piles formed on the surface of the dual different-shrinkage combined filament yarn are more stratified; and the loops with different sizes are tangled, so that the combined filament yarn looks fluffier, and the formed fabric is plumper and has stereo perception.

One-step method production process of high-strength high-shrinkage combined filament yarns

The invention discloses a one-step method production process of high-strength high-shrinkage combined filament yarns. The process comprises the following steps of S1 chip drying, S2 spinning of high-strength polyester filaments, S3 spinning of high-elasticity polyester filaments, S4 web connection of the high-strength polyester filaments and the high-elasticity polyester filaments and S5 winding.The invention relates to the one-step method production process of the high-strength high-shrinkage combined filament yarns, and the produced combined filament yarns have both high-strength performance and high-shrinkage performance. Sulfonic-acid-group negative dyeing bases capable of being dyed by cationic dyes, polydihydric alcohol for improving heat stability and dihydric alcohol for reducingthe crystallization performance are added, so that the performance such as hydrophilia, dyeability, lustre and flexibility is comprehensively improved. Under the effect of high-shrinkage polyester fibers, compared with conventional pre-oriented yarns / fully-drawn-yarn combined filament yarns, pile loops formed after thermal treatment are richer in layering sense, the appearance is fluffier, and a formed fabric is fuller, stereoscopic and larger in controllable range of the different shrinkage rate.

Viscose fiber and leecy fiber blended yarn and spinning technology thereof

The invention discloses a viscose fiber and leecy fiber blended yarn and a spinning technology thereof. The blended yarn comprises viscose fibers with the fiber content blending ratio of 60-70%, and leecy fibers with the fiber content blending ratio of 30-40%. The fibers are woven into the yarn through the spinning technology. Firstly, after the leecy fibers are subjected to opening and picking and cotton carding, the leecy fibers and the viscose fibers are mixed, then opening and picking and cotton carding are carried out, and the leecy fibers and the viscose fibers can be mixed to be uniform; due to the fact that the leecy fibers with the durable physical bacteriostasis function are added, the viscose fiber finished products can be prepared into the yarn with the antibacterial function directly through the following spinning technology, it is not needed to independently carry out antibacterial treatment on the viscose fiber finished products, the technology is simplified while the antibacterial effect is guaranteed, the production cost is reduced, fabric woven from the viscose fiber and leecy fiber blended yarn can be rapidly dyed, the colors are gorgeous, gradually varied and rich in layering sense after the fabric is colored, and multiple colors can be obtained through one time of dyeing.
