Process for sizing hard twisted yarns on warping and sizing combination machine

Abstract

The invention relates to a process for sizing hard twisted yarns on a warping and sizing combination machine. The process combines a warping procedure and a sizing procedure into one. The process has the following technical points: (1) sizing process: dipping twice and pressing twice, putting slurry into a back slurry tank, holding yarns by a front slurry tank, sizing at a low temperature and keeping the slurry at the temperature of between 65 and 75 DEG C, wherein an out-of-box twist is 8' and a sizing coverage factor is 70 percent; and (2) slurry prescription, wherein 20 kilograms of Nanpi-8 and 1 kilogram of CS-58 are used and the slurry contains 10 percent of solids. The process has the advantages of shortening the process flow, improving the work efficiency and reducing the manpower and material investment; and besides, the process is mature and stable, guarantees the product quality, and reduces waste.

Description

(1) Technical field [0001] The invention relates to a yarn treatment process in the textile field, in particular to a sizing process of strongly twisted yarn on a sizing machine. (2) Background technology [0002] At present, the sizing technology of strong twist yarn is the bottleneck technology in the whole cotton spinning field. The main problem is that in the traditional cotton spinning field, especially in the production process of white gray cloth, the Benninger sizing technology with a high degree of automation is generally used. Batch sizing machine for high-speed sizing. In the whole sizing process, relying on investing a lot of manpower and material resources for sizing, there is no reliable theoretical basis in technology, there are great chances and uncertainties, and at the same time, there is a lot of waste. Specifically reflected in: 1, the strong twisted yarn starts to twist before the sizing tank, and the yarns are entangled with each other, and cannot pass...

[0002] At present, the sizing technology of strong twisted yarn is the bottleneck technology in the whole field of cotton spinning. Batch sizing machine for high speed sizing

4. When carrying out sizing practice on a traditional sizing machine, as long as the machine is driven, there must be enough size, water, steam, etc. Once an accident occurs, the waste of yarn and size will be huge

The length from the front to the back of the traditional sizing machine is more than 60 meters. Once the driving is not smooth, at least about 100 meters of yarn will be wasted

At the same time, there is a relatively large waste in the recycling industry of slurry
