Recent Advances in Wet Chemical Processing Machinery.

Recent developments in wet processing machinery represent evolutionary enhancements to existing design. In most cases, control of conventional wet treatment processes has been improved through automation and electronic process control. The goal of most incremental design improvements is better production flexibility, versatility, and repr..

ITMA 95: Part III-Review of Washing/Dyeing Systems.

A overview of ITMA 1995 describes innovations and new designs in washing and dyeing machines. American Montforts Corporation showed a three color dye pad that featured automatic color measurement. American Superba offered three models in the MCK series of dyeing machines: the MCD/S multicolor machine for short runs, the MCD/L multicolor m..

Dyeing and Finishing of Narrow Fabrics.

Solubilizing or ionic dyes used on narrow fabrics include permanent acid dyes and temporary reduced vat dyes. Customers select narrow fabric dyes based on color, color uniformity, colorfastness, cost, overall appearance, and aesthetics. Batch dyes require ionic interactions and use large volumes of dyebath, whereas continuous dyes require..

염색공장폐수로부터 물, 화학약품의 회수 재이용에 대한 막의 사용 : 경제적인 접근

막 여과기술을 사용하여 염색공장 폐수로부터 염료, 조제, 물을 회수 재이용하는 실제적/경제성을 검토한 보고이다. 재이용에 영향을 주는 인자로는, 염색공정의 형태(배치염색/연속여색), 사용되는 염료의 종류, 배수상황(양, 염료/약제의 농도 등)이 있다. 예로서 천연섬유계 소재의 염색계를 들면, 반응염료나 크롬염료는 폐수로부터 회수 재이용은 불가능하다. ..

21세기의 염색

21세기가 되면, 환경에 대한 배려나 이것과 관련된 법규제가 염료제조공업 및 염색가공업에 있어서 기술혁신의 원동력이 될 것으로 생각된다. 컴퓨터테크놀로지를 구사한 저비용의 새로운 제조기기를 이용한 생산형태의 변화도 기술혁신의 중요한 인자가 될 것이다. 본고에서는 환경문제에의 대응, 신섬유·신직물에 대한 염색기술, 새로운 발색단을 가진 염료, 신염..

젯(jets)속에서 반응 염색물의 소우핑시 욕 교환식과 연속식 수세법에 대해서

고도로 공업화된 나라에서는 심각한 환경문제가 발생하고 있지만, 그 속에 놓인 섬유가공업계는 항상 새롭고 유효한 가공방법의 개발에 노력해왔다. 염료 제조회사에 의한 새로운 프로세스공학의 개발과 함께 기계회사에서도 개발, 개량에 중요한 역할을 다하고 있다. 최근 수위를 낮춘 욕의 수준으로 연속식 수세가 가능한 중요한 장치가 젯에 설치되어 매우 주목을..

Effect of Developing Bath Concentration on Dyeability in Vat Dyeing of Cotton.

Researchers used pigment padding techniques to investigate the effect of different developing bath concentrations (caustic soda and sodium hydrosulfite) on mercerized and unmercerized cotton fabrics during vat dyeing in the presence and absence of wetting agents. Results indicated that dye uptake values were highest at higher concentratio..

Direct Dyes on Cotton Grafted with 2-Vinyl-pyridine and quaternised with Alkyl Bromides or Epichlorohydrin

Researchers investigating chemical modification of cotton to improve its dyeability by direct and reactivedyes examined the modification of cellulosic fibers via grafting and subsequent quaternization. An experiment used C.I. direct Blue 78 and C.I. Dire

Rendering Flax Fibre Dyeable with Basic Dyes via partial Carboxymethylation.

An experiment concerning the partial carboxymethylation of bleached flax cellulose carried out a carboxymethylation reaction by treating the flax fibers with sodium hydroxide followed by sodium salt of monochloroacetic acid. Researchers evaluated the following four variables: concentration of monochloroacetic acid, concentration of sodium..
