Abstract

The invention relates to a dyeing and finishing method for a fabric, in particular to a dyeing and finishing method for a regenerated fabric, namely a regenerated nylon fabric. The invention also relates to the regenerated nylon fabric. The dyeing and finishing method of the regenerated nylon fabric comprises the following steps in turn: a) a pretreatment process; b) a dyeing process; c) a cleaning process; d) a heat setting process; and e) a texturing process. The dyeing temperature in the dyeing process is 120 to 135 DEG C, and a cleaning agent used in a cleaning process is an acidic reducing cleaning agent. The regenerated nylon fabric is treated by the dyeing and finishing method. In the invention, the technical problem that the strength of the regenerated nylon fabric is lower than that of common nylon fabrics is solved.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing method, in particular to a regenerated fabric dyeing and finishing method, in particular to a regenerated polyester fabric dyeing and finishing method. The invention also relates to a recycled polyester fabric. Background technique [0002] With the rapid development of our country's economy, the contradiction between the shortage of resources and the deterioration of the environment has become more and more obvious. The massive development and utilization of resources and the growth rate of industrial and domestic waste have reached a shocking level. According to incomplete statistics, the cumulative amount of garbage piled up in my country alone has reached more than 10 billion tons, occupying about 1.5 million mu of land. According to the survey of relevant departments, the value of renewable resources that can be recycled but not used in our country reaches more than 20 billion yuan every year...
