Study on the colloid mixing dyeing process of OPTIM.

In this text, the lanasol CE reactive dye was opted to the colloid mixing dyeing process of OPTIM. The colloid mixing auxiliary was added into the dyeing system to prepare for the low tempareture dyeing process of OPTIM by changing the interaction mode among dyestuff, auxiliary and fiber. It was found that, through the colloid mixing dyeing process, the dyestuff could absorb onto the surface immediately under the low temperature range, and the auxiliary PB could impart OPTIM a fluffier feel and a better rubbing fastness. The products' properties were compared between the colloid dyeing process under the optimised formula that it was 1. 0% ( owf) WR, 0. 12% ( owf) A, 0. 5% ( owf) PB and 2. 5% ( owf) HAc.
