Abstract:
A METHOD OF FINISHING SILK FIBROUS STRUCTURE WHICH COMPRISES TREATING THE SILK FIBROUS STRUCTURE WITH A SOLUTION CONTAINING AT LEAST ONE COMPOUND SELECTED FROM THE FOLLOWING GROUP: (A) UREA OF THIOUREA; (B) A MIXTURE OF FORMALDEHYDE-CONTAINING LOW GRADE CONDENSATION RESIN AND UREA OR THOUREA; (C) ALIPHATIC, ALICYLIC OR AROMATIC COMPOUNDS HAVING AT LEAST TWO HYDROXYL GROUPS AND HAVING MOLECULAR WEIGHT OF NO MORE THAN 400; (D) ALIPHATIC AMINES HAVING AT LEAST TWO GROUPS SELECTED FROM HYDROXYL AND AMINO AND HAVING MOLECULAR WEIGHT OF NO MORE THAN 400; DRYING THE TREATED FIBROUS STRUCTURE UNTIL THE MOISTURE CONTENT OF SAID FIBROUS STRUCTURE REACHES NO MORE THAN 10% AND THEN, TREATING SAID FIBROUS STRUCTURE WITH GASEOUS FORMALDEHYDE AT A TEMPERATURE OF NO LESS THAN 100*C. DURABLE AND HIGH CREASE-RESISTANCE IS OBTAINED WITHOUT ADVERSLY AFFECTING EXCELLENT PROPERTIES PECULIAR TO SILK FIBROUS STRUCTURE.
