Abstract:
|
In today's textile industry, the ultimate quick
response tool in wet processing is the use of garment
dyeing. The main limitation with this technology is the
wrinkled appearance and shrinkage of garment dyed products
during the dyeing cycle. If garments were assembled from
resinated fabrics, they would be more stable to shrinkage
and wrinkling, but the dyeability would be greatly impaired
by the presence of the durable press reactant. The current
procedure is to therefore apply a durable press finish
after garment dyeing, which is an expensive process.
In this thesis, resinated cotton fabrics were treated
in liquid ammonia in order to promote the subsequent
dyeability of these otherwise dye resistant fabrics.
Results of this work indicate the dyeability of resinated
cotton is improved with the use of the liquid ammonia
treatment prior to dyeing. In addition, resinated fabrics
treated with liquid ammonia exhibit greater durable press
performance compared to resinated fabrics without the
liquid ammonia treatment.
