Abstract

The invention provides a dyeing pretreatment process for pineapple leaves-cotton blended knitted fabric. The process is characterized by comprising the following steps: 1, soaking the pineapple leaves-cotton blended knitted fabric in oxygen bleaching solution at a temperature between 90 and 100 DEG C for 60 minutes; 2, soaking the blended knitted fabric in acetate solution at 50 DEG C for 10 minutes; 3, soaking the blended knitted fabric in soda solution at 80 DEG C for 30 minutes; and 4, feeding the blended knitted fabric into a KMM-260 singeing machine and performing gas singeing treatment,wherein the vehicle speed is 100 meters per minute, and the amount of oil is between 25 and 30. The process has the advantages of significantly promoting the dyeing properties of the pineapple leaves-cotton blended knitted fabric subjected to the pretreatment and guaranteeing color vividness, color fastness and level dyeing property thereof; in addition, the knitted fabric integrates the excellent performances of pineapple leaves and cotton and has a unique style.

Description

[0001] technical scope [0002] The invention relates to a pre-dyeing treatment process of pineapple leaf and cotton blended knitted fabrics. technical background [0003] According to the test report analysis, pineapple leaf fiber is the natural fiber with the best bactericidal properties found so far. After deep processing, the pineapple leaf fiber has a white appearance, soft and smooth, and can be blended with natural fibers or synthetic fibers. The woven fabric is easy to print and dye, sweat-absorbent and breathable, crisp and wrinkle-free, very comfortable to wear, especially suitable for tropical areas living people. In addition to the above advantages, pineapple leaf fiber also has strong natural bactericidal and antibacterial functions, which can effectively kill bacteria and inhibit the growth of fungi and microorganisms. The disadvantage is that the extracted pineapple leaf fiber has a high content of impurities, which leads to a deep background color of the fibe...
