Abstract:

The edges of single-weft knitted fabric was treated with paste to prevent the edges from curling during the open width pad-steam dyeing process. The sizing agents and their coating applied ways were optimized by comparing the curling rates and washing durability during open-width wet processing. As a result, the polyacrylate-polyurethane was used as a sizing agent. The suitable processes for medium weight and thick knitted fabric are as follows: the serrated coating is applied along the grain direction on the reverse side of fabrics, and the thickness of the coating reaches 0.2 mm. The width of the coating is no less than 2 cm. The results show that the method can effectively control the curling of the knitted fabric in the open width pad-steam dyeing process and has no effect on the dyeing performance.

Key words: open width dyeing, single-weft knitted fabric, polyacrylate-polyurethane, curling, washing durability
