Deweighting of dobby suede
2006
In consideration of structural features of superfine sea-island polyester fiber,a lot of experiments were performed to investigate the relationship between the warp-wise deweighting rate of dobby suede made of sea-island polyester and treatment temperature,concentration of NaOH and duration of treatment;the relationship between the shrinkage in warp-wise and weft-wise of the fabric and temperature and concentrate of NaOH;and the factors causing distinct difference in shrinkage between warp-wise and weft-wise.The permeability,breaking strength,bending rigidity and thickness of the treated fabric with different deweighting rate were determined and it was found that the best deweighting rate ranges from 18.9% to 21.76%.
