摘要:
Textiles containing blends of a proteinous animal fiber and polypropylene are rendered shrink-resistant by heating the textile to a temperature of about 165.degree.-250.degree. C. for a period of 0.1 to 60 seconds.
摘要:
A method of treating wool or cotton fibers to improve their resistance to, and recovery from, deformations encountered, for example, in the wrinkling of garments during wearing and in the deterioration of dimensions and shape of such articles during use or washing, which method comprises subjecting the fibers to a heat treatment while maintaining the regain within the range corresponding to the range of relative humidities encountered under normal use and for a period sufficient to allow the rearrangement of at least a proportion of the hydrogen bonds in the fibers in their minimum energy configuration. The method may form part of a process for rendering the articles dimensionally stable to machine washing and drying, in accordance with which the fibers treated as above are reacted with a reagent capable of forming permanent cross-links between reactive groups in the fibers.
