DYEING RANGES

Manufacturers in the textile dyeing sector at ITMA 1991 demonstrated their commitment to closer collaboration with the user, showing adaptability to the exaction requirements of customers. Dyeing ranges focused on solutions to the problems of shortage of skilled labor, quality and flexibility, waste reduction and environmental protection,..

DEVELOPMENTS IN DYEING AND FINISHING MACHINERY--ITMA 1991

The introduction of microprocessor controls and monitoring systems has been a major development in wet processing machinery. Instant online production information enables plant managers to better plan and schedule machines and workers. Global competition has reduced profit margins and made right-first-time production essential. The high c..

PROBLEM IN THE WET PROCESSING OF TEXTILES

A list of wet processing problems, the probable causes of such problems, and the remedial measures for such problems is presented. Pretreatment problems listed include uneven surface appearance, creases, uneven absorbency, uneven wetting during mercerization, and handling stains. Dyeing problems listed include shade matching, poor washfas..

CONTINUOUS PRETREATMENT AND DYENG PROCESSES

Online control and process automation is rapidly becoming the rule for finishing units. An overview of developments in the field of continuous pretreatment and dyeing processes at ITMA 1991 examines innovations in singeing, bleaching, washing, mercerization, and dyeing.

MODEL FOR COMPUTER-AIDES SIMULATION OF THE DRYING PROCESS IN PERFORATED DRUM DRYERS

A computer model simulates the performance of perforated drum dyers and can be used to give advice to customers and to investigate the effects of adjusting operating parameters. The model accepts machine specifications, performance parameters, and fabric-related information as input. Calculations are performed to determine fabric moisture..

KINETICS OF STAINING AND BLEACHING,

Food dyes and natural colorants are absorbed on the fiber surface and diffuse into the interior of the fibers. Stain removal by nonoxidative detergency involves diffusion of the staining agent from the interior of fibers and desorption from the fiber surface. The kinetics of stain removal by bleaching depend on the affinity of the stain t..

RANGE FOR WASHING OFF PRINTS ON WOVEN AND KNITTED GOODS

MCS's Lavaprint is capable of washing off prints on woven and knit fabrics. An open-width processing section consists of LU 23.25 washing units and an SN 32.05 conveyor belt relaxation unit on which the fabric is piled in small plaits. A rope processing section consists of WR rope processing modules. Machine functions include open-width i..

EFFECT OF CATALYST ON THE PORE STRUCUTRE AND PERFORMANCE OF COTTON CELLULOSE CROSSLINKED WITH BUTANECARBOXYLIC ACID.

The performance of the fabrics treated with several crosslinkers was highly dependent on the type of catalyst. The treatments were applied to all cotton print cloth via a pad-dry-cure process. Application levels were selected to effect approximately the same level of resilience with the different catalysts. The Wiley milled fabric via the..
