FIBER STRUCTURE HAVING SHAPE-MEMORY PROPERTY

摘要

PURPOSE:To obtain the subject structure having excellent washing fastness by using a shape-memory resin in combination with an isocyanate compound or treating a fiber structure with an organosilicon compound and applying a shape-memory resin layer to the fiber structure. CONSTITUTION:A fiber structure such as yarn, woven fabric or knit fabric of synthetic fiber, semi-synthetic fiber or natural fiber is immersed in a treating liquid containing a norbornene polymer as a shape-memory resin in combination with an isocyanate compound (e.g. tolylene diisocyanate) and dried and heat- treated to form 1g/m<2> of a resin layer or the fiber structure is immersed in an aqueous dispersion of an organic diene compound [e.g. n-beta-(aminoethyl)-gamma- aminopropyltrimethoxy-silane], dried, treated with the above shape-memory resin liquid and heat-treated to obtain a shape-memory fiber structure having excellent wash resistance and crease-recovery without deteriorating the tear strength and feeling of the original fiber structure. The process is especially suitable for the treatment of hemp cloth.
