A Dyeing and Finishing Process for Cotton Knitting for Special Purposes

Abstract

The invention discloses a dyeing and finishing process for an all-cotton knitted product suitable for special purposes. The process comprises the following steps: 1) grey cloth selection; 50S Xinjiang combed long staple cotton yarns are selected to be woven all-cotton double-side cloth by a selected Taiwan double-side circular knitting machine; 2) singeing: an Osthoff knitting and singeing machine is adopted to realize double-side singeing; 3) pretreatment: boiling-off of the cloth is carried out with a 745 chelating dispersant, a multifunctional refining agent, a 705 oil removal agent, a hydrogen peroxide stabilizer, caustic soda flack and hydrogen peroxide; 4) mercerizing: steps of using an unstressing scutching knitting mercerizing machine of a domestic self-developed Jiangsu Hongqi screen printing machine to realize mercerization and the like are carried out. According to the process, not only are all indexes required by military products met, but also the ventilation and heat dissipation, and moisture absorption and sweat releasing are improved, the wet rubbing fastness and burst strength are increased, product styles of conventional all-cotton knitted cloth are improved, and the market of the all-cotton knitted products is extended and expanded, so that the process has very strong market competitiveness.

Problems solved by technology

Conventional military products generally have the disadvantages of poor moisture absorption and perspiration and airtightness; in addition, conventional all-cotton knitted military products fully embody the advantages of moisture absorption and perspiration, but to some extent they cannot meet the color fastness and bursting performance. strength requirements

As the current military product orders have higher and higher specifications for textile fabrics, ordinary dyeing and finishing processes can no longer meet the requirements for this purpose.
