사람과 환경에 무해한 유연 가공제

「ISO 9000 시리즈」 (품질관리규격)에 이어 「ISO 14000 시리즈」 (환경감사규격)의 발효와 병행하여 통산성의 환경 JIS가 발효되어 환경에 대한 기업의 자세를 명확히 해야 하는 시대가 왔다. 화학 물질의 자연 환경에 대한 무해성을 측정하는 지표의 하나로 생분해성이 거론되었다. 생분해성은 광의적으로 미생물·생화학 작용에 의한 화학 물질의 분해성을 의미하..

호기 조건하 크롬아조메틴 염료의 미생물 탈색

호기 조건하에서 생장하는 혼합 박테리아 배양액을 사용하여 폐수에서 Cr 함유 아조메틴 염료 제거를 검토하였다. 이 균은 이전에 가죽을 다루는 공정의 폐수에서 분리한 것이기 때문에 특정 그람 양성균과 그람 음성균의 혼합물이다. 검토한 염료는 피리디닐메틸아미노페놀 Cr(Ⅲ) 착염의 퍼클로레이트이다. 염료 탈색 실험은 균배양액, 영양제, 염료(0.16-0.40m ml..

환경을 고려한 합성염료 (제1부) 단백질섬유 및 폴리아미드섬유용 철착염

본 보에서는 1:2형 Fe착염아조염료를 합성해서 종래의 1:2형 Cr 및 Co착염염료와 비교하였다. 1:2형 염료를 질량분석한 결과, 1:1형 염료 및 착염하지 않은 염료도 검출되었다. 일광견뢰도와 마찰견뢰도면에서 보면, 1:2형 Fe착염염료 가운데 블랙염료가 양모 및 나일론에 대해서 일광견뢰도가 높은 염료이다. Fe착염의 색은 갈색, 황갈색, 검은색에 한정되지만, 염..

Prevention of water pollution in dyeing processes of synthetic textiles

A brief description is given of a novel dyeing process for synthetic textiles. This process works completely without water, thus preventing or diminishing water pollution by dye houses. Using supercritical carbon dioxide as dyeing medium, several benefits like abandonment of any auxiliary chemicals (dispersants or surfactants) result in s..

Focused on time and water efficiency

In the past year dyeing machine developments have been dominated by cycle time and water savings.
