Description

Technical Field

[0001] The invention relates to a method for preparing a clip-type warp-knitted roller brush flannel cloth, and belongs to the technical field of textiles. Background Art

[0002] People have higher and higher requirements for house decoration and pay more and more attention to the appearance of the machine, and the demand for paint rollers has increased accordingly. However, the velvet fabrics used in existing paint rollers for surface painting have a single appearance, mostly plain and vertical stripe products, which cannot meet the public's aesthetic taste.

[0003] By using a circular knitting machine with 1*3 tissue brush velvet machine and two different yarn arrangement methods for raw materials, velvet clipping effects with different patterns can be achieved, but there are disadvantages such as low output and unstable product quality. Common warp knitting products only have plain and vertical stripe velvet, which cannot achieve the starry and scattered clipping effects of circular knitting velvet. Although filament raw materials can achieve clipping effects by changing the two raw materials' screen adding methods and yarn arrangement methods, the cost is high and there are also quality problems caused by inconsistent raw material shrinkage. Summary of the invention

[0004]
