Dyeing and finishing process of tencel wool blended fabric

Abstract

The invention discloses a dyeing and finishing process of a wool and tencel blended fabric. The dyeing and finishing process sequentially comprises the following steps of grey cloth inspection, seam turning, singeing, desizing and scouring, bleaching, drying, rolling, spraying, rolling and dyeing, loose type drying, softening finishing, air washing, tentering, preshrinking, fulling, fluffing, shearing, tank steaming, inspection and finishing and finished product obtaining. According to the tencel and wool blended fabric, in the dyeing process, an auxiliary mixed solution containing a levelingagent and a retarding agent is sprayed, an auxiliary makes contact with gray fabric firstly, then dye makes contact with the gray fabric for dyeing, and the auxiliary is separated from the dye, so that the dyeing rate between tencel fibers and wool fibers is close, and the leveling property of the fabric is improved. By adopting a dye infiltration winding dyeing method and a winding fixation method, the gray fabric does not need to be completely soaked in a dye vat, the bath ratio of dyeing and fixation is reduced, and the liquid absorption amount and the liquid absorption time of tencel are reduced, so that the dyeing rate between the tencel fibers and the wool fibers further tends to be the same, and the level dyeing property of the fabric is further improved.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of Tencel and wool blended fabrics. Background technique [0002] Tencel, cotton, wool, and hemp can form blended fabrics such as Tencel / Cotton, Tencel / Wool, Tencel / Hemp, etc. Due to the high swelling property and fast adsorption speed of Tencel, most Tencel blends are A variety of dyes, multi-bath method to separately dye various fibers blended. However, a variety of dyes are used for dyeing separately and cannot be dyed at the same time. Due to the inconsistent color absorption of different fibers, there are color differences in the dyeing, resulting in color flower and color difference; and the multi-bath dyeing method has a long process, a large bath ratio, and environmental protection problems. At the same time, the tencel fiber itself swells greatly after being exposed to water, and dyes and auxiliaries can easily enter th...

Problems solved by technology

However, a variety of dyes are used for dyeing separately and cannot be dyed at the same time. Due to the inconsistent color absorption of different fibers, there are color differences in the dyeing, resulting in color flower and color difference; and the multi-bath dyeing method has a long process, a large bath ratio, and environmental problems. At the same time, the tencel fiber itself swells greatly after being exposed to water, and dyes and auxiliaries can easily enter the interior of the fiber, so the initial dyeing rate is quite high, and it is easy to cause the front and rear and left and right color differences of the tencel fiber itself
