Problems solved by technology

[0004] Synthetic fiber filament has the advantages of good wear resistance, good elasticity, softness and smoothness, but it is prone to static electricity during the sizing process of the staple fiber sizing machine, the yarn diverges, and there are many warp beam breaks, which are difficult to straighten out. Smooth fiber surface, not easy to sizing
[0005] Patent CN106995963A "Nylon filament elastic yarn treatment process suitable for sizing of staple fiber sizing machine" proposes a treatment process for nylon filament elastic yarn suitable for sizing of staple fiber sizing machine. The sizing includes low The PVA content of the polymerization degree is as high as 32.8%. The high PVA (polyvinyl alcohol) content is not conducive to environmental protection, and it adopts the shortened yarn path process route, opens a single size tank for production, does not use cylinder pre-drying, and can only produce a small number of heads. , Varieties with few flowers and colors, poor variety adaptability
[0006] Patent CN103835089A "A sizing process for producing DTY filament varieties using a spun sizing machine", which proposes a sizing process for producing DTY filament varieties using a spun sizing machine, which adjusts the speed of the spun sizing machine Reduce to 20-25m / min, the reduction of the speed will have a certain impact on the output of the sizing machine, and it adopts oiling treatment. In order to ensure that the filament is dried after oiling, the temperature of the drying cylinder must be kept at 150-155°C , high temperature will affect the color fastness of the dyed warp beam, and it is easy to cause the fiber to fade, and the over-dried yarn is easy to be damaged, and it is easy to cause thread breakage during yarn separation
In addition, high-temperature drying consumes a lot of steam, which is not conducive to energy saving and consumption reduction

Abstract

The invention belongs to the technical field of textiles, and specifically relates to a sizing process of a synthetic fiber filament on a short fiber sizing machine. The synthetic fiber filament adopts a production process of dyeing first and then sizing; the sizing process is: sizing - drying - moisturizing treatment - antistatic treatment; wherein low-viscosity slurry is used for sizing at roomtemperature when sizing, a single-group drying process is used for drying, and then the yarn after sizing is treated with moisturizing and antistatic treatment. According to the invention, the PVA content in the sizing agent is low; the sizing is performed at room temperature, which ensures the color fastness of the fiber and is more environmentally friendly; meanwhile, by optimizing the drying process route and adding the moisturizing and antistatic treatment process, the defects that the filament fiber is easy to be static during the sizing process on the short fiber sizing machine, the yarndiverges, and the warp beam is broken are perfectly solved; and the weaving efficiency is improved, the steam is saved by more than 30%, the double sizing tank production can be realized, the vehiclespeed is stable, the variety production adaptability is better, and the sizing process of the synthetic fiber filament on the short fiber sizing machine meets the requirements of low-consumption andenvironmentally friendly sizing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a sizing process for synthetic fiber filaments on a short fiber sizing machine. Background technique [0002] Warp yarn sizing is a key preparation process for fabric weaving. Unsized warp yarns have prominent hairiness on the surface, high surface friction resistance, and insufficient cohesion between fibers. During the weaving process, the fiber structure is loose and there are many broken ends, making it impossible to weave. The purpose of sizing is to endow the warp with the ability to resist external complex mechanical forces, improve the weavability of the warp, and ensure the smooth progress of the weaving process. [0003] The spun sizing machine is a sizing machine mainly used for sizing cotton and cotton blended yarns. The main technological process of the spun sizing machine is that the yarn is drawn out from the warp creel by several warp beams, and is dr...
