Beam sizing process of high-count color yarn

Abstract

The invention discloses a beam sizing process of high-count color yarn. A size mixing formula comprises modified starch, polyvinyl alcohol, acrylic acid, wax sheets and a penetrant. The formula is sized by a double-size sizing machine, and the sizing process parameters of the double-size sizing machine are as follows: the sizing speed is 40-60 m / min-1, the size tank temperature is 95-98 DEG C, thesize viscosity is 6-8 s, the size solid content is 10%-12%, the moisture regain is 4%-5%, the sizing percentage is 10%-15%, the main size press force is 18-24 kN and the auxiliary size press force is8-12 kN. The size formula is simple, high in permeability and high in sizing percentage, the sizing quality is easy to control, the prepared size has high strength, low elongation reduction rate andlittle hairness, and the process is simple, applicable to sizing of high-count pure cotton color yarn and sizing of blended yarn taking cotton yarn as a main material and has very great significance in development of yarn-dyed pure cotton high-count and high-density products.

Description

technical field [0001] The invention relates to the technical field of textile weaving, in particular to a warp beam sizing process for high-count colored yarns. Background technique [0002] With the continuous improvement of people's living standards and production technology, high-count and high-density pure cotton fabrics are more and more popular. Dyeing and other steps make yarn-dyed pure cotton high-count and high-density products very difficult in sizing and weaving. Warp beam sizing is an important process in textile processing, and its main purpose can be summarized as reinforcement, friction reduction and elongation retention, thereby improving warp weaving performance and meeting weaving requirements. However, due to the fine yarn count, low strength, high twist, high hairiness and poor yarn permeability of high-count dyed yarn, the commonly used size formula and sizing process cannot meet the weaving requirements of high-count dyed yarn. The reason is that yar...

However, due to the fine yarn count, low strength, high twist, high hairiness and poor yarn permeability of high-count dyed yarn, the commonly used size formula and sizing process cannot meet the weaving requirements of high-count dyed yarn

The reason is that yarn-dyed pure cotton high-count and high-density warp yarns are dyed, and the single yarn strength, elongation, hairiness and other indicators are worse than the original yarns.
