Abstract

The invention discloses a bamboo fiber and silk interlaced fabric dyeing and finishing process which comprises the following steps: (1) sewing a gray fabric; (2) presetting the fabric; 3) performing pretreatment, namely desizing the preset fabric, wherein a desizing solution contains sodium hydroxide, hydrogen peroxide and amylase, and the temperature of the desizing solution is 30-65 DEG C; (4) dyeing, namely soaking the fabric for 25-35 minutes in 75 percent of an alcohol solution, and dyeing bamboo fibers by low-temperature disperse dyes at 50-100 DEG C and in a dye bath with the pH value of 5.2-6.1, performing reduction clearing on the dyed bamboo fibers for 10-18 minutes at the clearing temperature of 55-60 DEG C, and performing silk dyeing after reduction clearing, wherein a reduction clearing solution comprises 0.3g / L-1.2g / L sodium hydrosulfite, 1.2g / L-2.3g / L an anionic detergent and 0.3g / L-1.2g / L sodium bicarbonate; (5) dehydrating; and (6) performing after-treatment, namely padding the dyed fabric in a hydrophilic aminosilane softening agent, and drying and performing tentering setting on the padded fabric at 85-95 DEG C. The fabric has a high degree of dyeing, integrates the advantages of silk and bamboo fibers, and is cool as well as good in hand-feeling.
