Abstract

The invention discloses a pad dyeing process for a flame-retardant polyester / modacrylic blended fabric. The process specifically comprises the following steps: 1, desizing and scouring the flame-retardant polyester / modacrylic blended fabric; 2, pre-setting the fabric subjected to desizing and scouring in the step 1; 3, dyeing the pre-set fabric in the step 2; and 4, performing after-treatment on the fabric dyed in the step 3. According to the pad dyeing process for the flame-retardant polyester / modacrylic blended fabric disclosed by the invention, continuous large-scale production can be realized, the production efficiency is improved, and the service requirements of the flame-retardant fabric are met.

Description

technical field [0001] The invention belongs to the technical field of textile chemical dyeing process, and relates to a pad dyeing process of flame-retardant polyester / acrylic chloride blended fabric. Background technique [0002] In recent years, the global safety and protection textile market has shown a rapid growth trend, and the market demand for high-performance fibers and fabrics has increased significantly, although they are widely used in special fields such as fire protection, police, welding, and petrochemicals. However, due to the high price of high-performance fibers, it is difficult to be widely used in a wide range. As one of the important functional fibers, flame-retardant polyester has its unique advantages—permanent flame retardancy and low price. Its fiber fabrics and blended fabrics are widely used in clothing, curtains, curtains, bedding, vehicle interior materials, etc. It can even be used in fire protection, police, welding, petrochemical and other s...
