Problems solved by technology

[0002] The treatment process of yarn-dyed weft yarn before weaving is tight winding→loose winding→normal dyeing→post-processing→softening→drying→tight winding. Generally, the strength reduction is about 10%, and the hairiness increase rate is about 30%, resulting in high weft stop of the loom, low weaving efficiency, and poor cloth surface effect after weaving.
[0003] Use the traditional warp beam sizing process to sizing the weft yarn package. The package yarn is warped first, and the yarn on the warp beam is sized on the sizing machine. After sizing, the yarn on the warp beam is guided into a package yarn, which is time-consuming and expensive The yarn is easy to twist and break, and the traditional warp beam sizing process is not suitable for yarn-dyed weft yarn sizing

Embodiment 1

[0007] Embodiment 1: select 200kg pure cotton weft yarn for use, and the yarn count is 10 English count single yarns. Its technical solution is:

[0008] Step 1) For normal bobbin dyeing, the softening process is to add smoothing agent and cycle dyeing for 5 minutes;

[0009] Step 2) The liquid slurry adopts the acrylate liquid slurry QB-918J produced by Qingdao Jimo Qingbao Slurry Factory, adds 10kg of liquid slurry with a solid content of 25%, and processes for 5 minutes;

[0010] Step 3) After normal drainage and dehydration, enter the drying process.

Abstract

The invention provides a technological method for sizing dyed weft yarns. The technological method is characterized by sequentially comprising working procedures of normally dyeing yarns; sizing the yarns by the aid of liquid; drying the yarns. A softening procedure for dyeing the yarns includes circularly dyeing the yarns by the aid of smoothing agents for 5-10 minutes, and the working procedure for sizing the yarns by the aid of the liquid includes circularly dyeing the yarns by the aid of liquid sizing agents for 5-10 minutes; the liquid sizing agents are acrylic ester liquid sizing agents with solid contents of 25% or PVA (polyvinyl alcohol) liquid sizing agents with the concentration of 100 g / L, and a mass ratio of the liquid sizing agents to the dyed weft yarns is 20-50:1000 when the liquid sizing agents are acrylic acid sizing agents; a mass ratio of the liquid sizing agents to the dyed weft yarns is 10-20:1000 when the liquid sizing agents are the PVA sizing agents. The technological method has the advantages that the strength of the yarns treated by the aid of the technological method can be improved by approximately 10%, the hairiness of the yarns can be reduced by approximately 30%, and the weaving efficiency and fabric surface effects of woven color-spun fabrics can be greatly improved.
