PROBLEM TO BE SOLVED: To obtain a fiber product having good touch and excellent in crease resistance, puckering property after repeated washing, wash and wear property and shape-retaining property by subjecting cotton fiber-containing fiber structure to crosslinking and modification treatment. SOLUTION: Cotton spun yarn is subjected to immersing treatment in a liquid ammonia and ammonia is removed by hot air and the spun yarn is woven and knitted and the resultant woven and knitted fabric is sized, scoured, bleached, subjected to liquid ammonia treatment, impregnated with a treating liquid containing a compound having active hydrogen capable of carrying out methylolation, e.g. dihydroxyethylene urea, dried and sewn and the sewn product is subjected to formalin vapor phase treatment to provide the objective fiber product in which cotton fiber constituting the sewn product has <=45 deg. X ray orientation angle obtained from the fiber bundle and formalin amount bound by the crosslinkage modification is >=0.6wt.% and >=4 rating puckering after 5 times repeated washing according to JIS L-0217 103 method. |
