산 세정 데님 황변에 영향을 주는 금속염

금속염은 과망간산칼륨에 의한 습식 처리되는 산 세정 데님에서 황변 변색물의 형성 가능한 안트라닐릭산(anthranilic acid)과 같은 인디고 산화 부산물과 결합 가능성이 있다. 원자흡수분광법에 의한 분석으로 데님 금속염의 감소는 황변의 감소와 관련이 있다는 것을 보여 주었다. 칼슘염이 87％까지 진행된 공정 후에 증가하였는데 이는 황변에 칼슘이 개입했음을..

화이트워시 데님의 광에의해 황변을 일으키는 인자의 평가 : Ⅰ. 추출 가능한 유기/금속이온 확인

화이트워시 데님 직물의 광에의한 황변 원인을 결정하기 위한 프로젝트로서 진에서 유기/금속 이온을 확인하기 위해 추출 분석을 하였다. 광에의한 황변 전후의 진을 에탄올로 추출하여 GC-mass spectroscopy로 분석한 결과 지방산과 고분자량의 탄화수소가 추출된 주요 유기 혼합물이었다. 이산틴(isatine)과 에틸 안트라닐레이트(ethyl anthranilate)는 훨씬 적게 ..

Effective steam pressing of wool garments

Improved processing procedures in garment manufacturing

Aspects of the preparation of grey cotton fabrics prior to dyeing were investigated. Shrinkage behaviour of poplin and twill fabrics at different pretreatment stages and at various points in the garments was studied. The effects of sewing tension and stitches per inch on puckering were also examined, as was the influence of different prep..
