Synthesis of super absorbent water resin and study of the resin absorption dye

Super absorbent water resin was synthesized by solution polymerization, which was acrylic acid as monomer, K₂S₂O8 as initiator, N,N' - methylenebisacrylamide as cross linker. The resin synthesized was used as absorption dye. Structure of the resin, amount of the resin, concentration of dye and time of absorption on power of dyeing were ..

Calculating the dye consumption in a continuous production line (Russian)

The effect of impregnating conditions (time, temperature, dye bath composition, expression) on the sorption and diffusion processes is examined in relation to the dye consumption in continuous dyeing. An example features the use of direct dyes on different constructions. An empirical formula for calculating the dye consumption is presente

Blend uniformity of a filament and staple composite yarn and its effect on dyeing

This study describes the effect of spread width and spreading behavior on the blend uniformity of a cotton/polyester filament blend yarn and the latter's effect on dyeing. The results show the wider the spread width, the more uniform the spreading among individual filaments. Higher blend uniformity also ultimately results in more uniform ..

Dyeing characteristics of acala cotton seed fibers

The dyeing characteristics of fibers from three Acala cotton varieties, ie, Maxxa, SJ-2, and SJC-9, are investigated using direct and reactive dyestuffs along with the Goldthwait cotton maturity test. Dyed and less-dyed fibers are detached from the dyed seed fibers, separated, and characterized by seed fiber weight, single fiber strength,..

Induction of Anitoxidant Enzyme Activity in Cotton

Research on the induction of antioxidant enzyme activity in cotton transferred callus tissue from a control and a sodium chloride tolerant cell line to culture tubes that were sodium chloride-free; amended with sodium chloride; or amended with sodium chloride, abscisic acid, hydrogen peroxide, or xanthine and xanthine oxidase. harvesting ..

Biological Renovation and Reuse of Spent Reactive Dyebaths.

Researchers investigated methods to renovate reactive dyebaths biologically and reuse the high salt containing mixture in the dyeing process. Bath assays used an anaerobic methanogenic culture enriched from municipal sewage sludge to evaluate the potential toxicity of nine commercial reactive dyes to anaerobic microorganisms. Researchers ..

An Investigation into the Use of Supercritical Fluid Technology for Analytical, Process and Environmental Applications in Textiles.

Researchers examining the solubility and transport aspects of supercritical fluid (SCF) extraction methods focused on disperse dyeing in supercritical carbon dioxide and developing a detector that would allow the study of SCF extraction in real time. Using four different disperse dyes, an experiment quantitatively compared SCF carbon diox..

Real Time Analysis and Control of Batch Dyeing Processes.

A report on recent progress of the National Textile Center's dye applications research group (DARG) in real time monitoring, modeling, and control of batch dyeing processes describes the modification of the flow injection analysis (FIA) system to enable injection of a small volume of dyebath into a high performance liquid chromatograph of..

Thies: New Machines for Fibers and Changing Markets.

Thies's new Coesfeld air stream dyeing machine provides woven and knit lyocell fabrics with the necessary tumbler-like surface treatment and achieves the necessary high circulation, good opening, and movement during finishing for microfiber fabrics in rope form. The high temperature aerodynamic machine provides liquor ratios as low as 3:1..

Vestowax P 930 -- Pigment Carrier for Dyeing PP Fibers.

Huls' Vestowax 930 polyolefin wax for formulating polypropylene (PP) fiber pigment preparations allows the manufacture of fine titer fibers of 2 dtex. Conventional polyethylene waxes show poor compatibility with PP. Conventional PP waxes disperse poorly and cause pigment agglomerations that lead to fiber tear and collect in spinnerets cau..
