The printing of polyester/cellulose blends‐a new approach

This paper introduces a new dye system for the printing of polyester/cellulose blends. The new system is based on a combination of disperse dyes containing diester groups and reactive dyes containing a monochloro‐s‐triazinyl reactive group. By reference to published work on the reaction mechanism of monochloro‐s‐triazinyl reactive dyes with cellulose the development of a new approach to bring about reactive dye fixation in essentially neutral pH conditions is discussed. Practical application details of the new dye system are emphasised.
