섬유반응 시스템에 의한 셀룰로오스섬유 염색공정 개선

셀룰로오스섬유의 반응염색에 있어서 문제점(염료의 낮은 효율, 착색폐수, 알칼리/전해질의 다량 사용)을 개선하기 위해서 근래에 개발된 방법을 검토하고, 그 개선 가능성을 평가하였다. 다관능성 반응염료의 개발, 인도졸 시스템과 같은 가교방법의 적용도 서술되어 있지만, 셀룰로오스섬유의 화학개질에 의한 염색성 개선을 중심으로, 특히 저자의 최근 연구를 정..

NO₂ 가스에 의한 C.I.Disperse Blue 3의 변퇴색 거동

JIS-L-0855의 표준염색포와 C.I.Disperse 3를 다른 농도로 염색한 아세티이트 염색포를 사용하여 NO₂ 가스의 농도와 대기중의 습도가 C.I.Disperse 3 염료의 변퇴색에 미치는 영향을 조사하였다. 변색실험은 시료를 시판 NO₂ 가스, 환경대기 그리고 JIS-L-0855의 NO₂ 가스 발생장치에 노출시켜 행하였고, 결과는 NO₂ dose (NO₂ 농도×노출시간)와 색차(ΔΕ)의 관..

CSIRO에서의 염색기술에 대한 최근 진보

CSIRO에서는 최근 염색 관련 연구테마를 결정함에 있어서 ①염색 양모제품의 품질유지 ②환경에 대한 영향을 최소한으로 억제시키는 쪽으로 중점을 두고 있고, 이에 따라 추진되는 연구과제를 소개하면 다음과 같다. (1)저온염색∼고온염색에 따른 양모의 품질저하는 카드나 정소면의 기계처리공정에서의 생산량 감소 및 최종제품의 항변, 마모·파열 강도 등의 물성..

Process for printing and dyeing of textiles

A method for printing and dyeing of fabrics with acid dyes is claimed. An aqueous solution containing specific compounds is initially printed on the material, after which it is subjected to a fixing process where the fibres are modified. The material is subsequently dyed by the exhaust or padding method. IPC D06P.

Removal of excess dye from new textiles

A process forremoving excess dye from a newly manufactured printed or dyed fabric or yarn comprises treating the fabric or yarn with a wash liquor containing an enzyme exhibiting peroxidase activity and a suitable source of hydrogen peroxide or an enzyme exhibiting suitable oxidase activity and a source of oxygen. IPC C11D.

Linen fabrics: preparation, dyeing and finishing

This history of linen is outlined and the traditional difficulty associated with dyeing it is noted. The cultivation of flax and the preparation of flax fibre prior to yarn production (pulling, retting, breaking, scutching and hackling) are described. The composition and physico-chemical characteristics of linen are presented as are its r..

Bar codes for controlling textile process changes.

A pilot scale range for the continuous pad dyeing and drying of textiles was automated using bar codes fixed to the surface of the fabric and read by a scanning laser reader at the beginning of the production line. The signal generated by the reader was digitized, identified and transmitted to a micro-computer. The bar code identified the..

New Emerizing Machine Series.

Mortamet International's ER5X and ER5S emerizing machines are equipped with five or six single or double sided emery rollers with working widths from 1,800 to 3,000 millimeters. The quality and effect of emerizing can be changed by clothing the rollers with a variety of emery papers. Paper replacement takes less than 2 minutes. Clothing l..

Trends in Chemical Processing Techniques for Cleaner Environment.

Recent developments in the chemical processing of cotton fabrics in India are being driven by environmental concerns. Envirnmental guidelines are a component of the ISO 9000 standards, and adherence to environmentally responsible production methods is likely to become a prerequisite for export to Europe. New production processes seek to l..

Fading of Azo Reactive Dyes by Perspiration and Light.

A test method developed by the Association of Textile Technology (ATTS) in Japan evaluated the combined perspiration fastness and lightfastness of azo reactive dyes on cotton fabrics. The experiment also compared ATTS test results with results obtained using conventional lightfastness tests. Reactive azo dyes contiaining an H-acid or K-ac..
