Dyeing and finishing method for long staple cotton and Lyocell bamboo fiber blended high count yarn-dyed shirt fabric

The invention relates to a dyeing and finishing method for a long staple cotton and Lyocell bamboo fiber blended high count yarn-dyed shirt fabric in the production of textile dyeing and finishing. The method comprises the following steps: step 1, before weaving the fabric, conducting pre-treatment before dyeing on blended cheese and dyeing the blended cheese; and step 2, after the weaving of the fabric, carrying out pre-treatment and post-treatment on the woven fabric. The step 1 sequentially comprises the following procedures: conducting pre-treatment before dyeing, dyeing, hot water washing (80 DEG C for 10 min), acid cleaning (70 DEG C for 10 min), soaping (85 DEG C for 10 min), hot water washing, cold water washing, color fixing, softening, discharging from a vat and stoving on the cheese; and the step 2 sequentially comprises the following procedures: conducting singeing, bio-enzyme desizing, mercerizing, liquid ammonia finishing, non-ironing resin finishing on the fabric to obtain the finished product. The dyeing and finishing method has the advantages that the fabric embodies good properties of long staple cotton and Lyocell fiber; and through the pretreatment and the post-treatment, and particularly due to the utilization of resin finishing technology, the elasticity of the fabric is improved, and creasing is reduced, so that the fabric provided by the invention is a high-range fabric with favorable softness and comfortableness.
