Abstract: Hitherto there has been no practical pad-dwell process for wool piece goods which could be carried out without using large amounts of textile assistants. In addition, it has been necessary with all these processes to supply energy. Furthermore, large amounts of urea have always been used, which inevitably resulted in a high degree of waste water pollution.

To prevent the formation of a frosting effect and to obtain deeper shades it is expediently possible also to add to the padding liquor nitrogen-containing ethoxylation products, in particular ethoxylated fatty amines, and/or alkyl polyglycol ethers.

Abstract: Poor wet fastness properties and unsatisfactory fastness to thermofixing of dyeings on flame-retardant PES fibers with conventional disperse dyestuffs preclude the deployment of textile material of this type in the industrial wear and contract business, such as for utilitarian textiles, sportswear or the like. The reduced boil-wash stability of such disperse dyestuffs on the modified fibers can lead to washing problems because of the risk of bleeding.Using disperse dyestuffs which contain highly polarized groupings in the molecule for dyeing flame-retardant PES fibers substantially improves the dyeing results in respect of the fastness properties sought and hence opens up further areas of use for said types of fiber. The flame-resistant properties of the textile material are not impaired.
