Fabric Compatibility and Cleaning Effectiveness of Drycleaning with Carbon Dioxide.

The use of liquid carbon dioxide in drycleaning is an environmentally safe alternative to perchloroethylene solvent. Chemical and operational costs for the technology are also lower than those of conventional technology. Experiments conducted with carbon dioxide in both small scale and pilot scale tests focused on fabric compatibility. Re..

Color Loss on Silk.

The most common drycleaning problems with silk fabrics include unstable dyes and finishes. Damage may appear in silk apparel on first drycleaning or after several drycleanings. Problems arising from solvent soluble dyes are due to the manufacturer's failu

Continuous Rope Washing Machine for Woven and Knitted Fabrics.

Mezzara's Concord continuous rope washing machine for natural and manmade woven and knit fabrics permits the use of a wide range of treatments, including pretreatment; neutralization after alkalinization or mercerization; relaxation; and washing after bleaching, pad-batch processing, printing, or dyeing. The unit consists of a variable nu..

Stenter Section.

Knit fabric tentering machines should have contact guided fabric paths driven by a vertical chain return. Vertical chain returns also provide clean pinning results and a smaller gap between fabric and nozzles. A trough shaped feed table between the pad an

Finishing Knits for Low Shrinkage.

New techniques used in Santex AG dryers allow knit fabrics to shrink in a natural way, producing stable knit fabrics with a residual shrinkage potential of less than 5 percent. Residual shrinkage is determined by the method used to manufacture the fabric and the apparel item. Santex machines include low tension machines for detwisting, sl..

Biological Renovation and Reuse of Spent Reactive Dyebaths.

A study will examine the use of an anaerobic bioreactor system for the color removal and reuse of spent reactive dyebaths. Researchers will biologically renovate reactive dyebaths and reuse the high salt containing mixture in the dyeing process. The proje

Savings in Water Consumption Productivity ＆ Quality Improvements.

Henriksen's recent developments in jigger technology eliminated such problems as dark edges and light endings. The new jigger features achieve even temperatures, avoid evaporation from the fabric roll, and reach speeds of up to 200 meters per minute. Henriksen's Eco-rinse system, incorporated in its Vacu-Jigger, reduces the amount of rins..

Fine Structure of Cupra, Tencel and Anisotropic Diffusion of Dye Molecules in Fibers.

Researchers applied a new preparation process, based on the ability of optical density to enhance the cross sectional views of fibrous materials, to detect the skin core structure of cupra and Tencel filaments. Microphotospectroscopic analysis determined the characteristic concentration gradient of dye molecules along the fiber axis. For ..

Purifying of waste water from textile finishing by a membrane process (German)

Trials with a membrane filtration technique for treating finishing effluents are described. The method is found to be useful in treating partial waste water flows. The processing of total waste water flows should be avoided for technical and ecological reasons. A vital reason for this are the large quantities of waste water which would ne..

Study of the low-sludge treatment and recycling of printing effluents (AIF No. 9699) (German)

A method of treating printing effluents using a combination of chemical oxidation and aerobic biology and to recycle the effluents in various printing works is described. It is found that the effluents have been adequately treated and that residual printing pastes (0.3-1 ㎏/㎥ effluent) can be added with no problems. The effluents can thu..
