Abstract

The invention discloses a one-bath method of three types of fibers. The one-bath method comprises fabric assorting, desizing, dyeing, dye fixation, fabric unfolding and setting. The one-bath method utilizes a fabric obtained by interweaving of three fibers such as warp-wise terylene, broad-wise nylon and natural cotton. The dyed fabric subjected to finished product processing and dyed by the one-bath method of three types of fibers has good handle, good massiness and good water absorptivity. The one-bath method of three types of fibers reduces water, power and vapor energy consumption in production, reduces pollution discharge and a cost and has a wide application range.

Description

technical field [0001] The invention relates to the field of dyeing, in particular to a method for dyeing a cloth formed by interweaving polyester, weft nylon and natural cotton fibers. Background technique [0002] Warp direction polyester (Terylene warp), weft direction nylon (Zonal nylon) and natural cotton (Natural Cotton) are three commonly used fabrics. It is a very important step to dye fabrics in the textile industry. Professional dyeing equipment: fabric distribution, stitching, desizing, oxygen bleaching, dyeing, setting, finishing and other processes to produce finished fabrics are dyed fabrics. The dyeing method used is highly adaptable, but the operation is complicated, the dyeing is uneven, and the color is unstable. At the same time, the wastewater pollution in the dyeing process is serious, endangering human health, and the cost of sewage treatment increases, causing certain pressure on enterprises. Contents of the invention [0003] The object of the pres...
