Cotton -- The King of Fibres -- Part XIX.

An overview of cotton fabric processing addresses reactive printing. Innovative binder systems allow fast white pigment printing that is washfast. Indian manufacturers use these pigment white prints as overprints or with reactive printing to yield half tone and full print effects. Reactive printing uses conventional sodium bicarbonate and..

The Influence of Steam Pre-treatment on the Wettability and Dyeability of Ecru Fabrics.

The FKO system for continuous chemical impregnation during dyeing uses high temperature steam prior to impregnation to improve liquor penetration and chemical reactivity. Saturated or superheated steam under pressure in a sealed chamber purges air from the fabric, which increases vapor and liquid penetration. A pressurized labyrinth seali..

Frequently Encountered Problems in Textile Wet Processing and a Diagnostic Approach for Prevention/Solutions.

An overview of cotton fabric wet processing problems addresses bleaching and seed marks in cotton fabrics, fabric washing and pH correction before dyeing, variations in fabric whiteness, and laboratory testing and problem prevention. Low pH and rapid peroxide decomposition bleaching conditions leave seed marks that show up as black or bro..

Frequently Encountered Problems in Textile Wet Processing and a Diagnostic Approach for Prevention/solutions.

Many textile processing problems relate to the improper selection of chemicals. Surfactants assist in wetting and emulsifying unsaponifiable materials and are important in scouring cotton/polyester blend fabrics. Temperature has an inverse effect on the solubility of nonionic surfactants. The hydrophilic/lyophilic balance is an index of s..

Washfast Dyeing on Polyester and Acetate.

Reductive hydrosulfide aftertreatment of dyed polyester, polyester blend, and acetate fabrics exhibits a number of problems, including large amounts of water, significant amounts of sulfur in the effluent, the need for an alkaline mixture, and a solid treatment material. Cyclanon R, an organic liquid aftertreatment, addresses these issues..

DOS&DYE -- Evolution toward the Future.

Tecnorama's modular DOS&DYE achieves automation in dyeing laboratories to improve the ability to product color qualitatively. Automation permits rapid amortization, better utilization of operators, and better laboratory management. The unit processes a wide range of sample types, including raw fibers, yarns in skeins or bobbins, woven and..

Catalogue of Types of Fabric Defects in Grey Goods.

A handbook on greige fabric defects addresses defects in the warpwise and fillingwise directions and those with no directional dependence. Chapters provide visual descriptions and alphabetical codes for such defects as striping, thin places, lashed-in weft, extraneous yarns, fly, broken and short picks, barre, stains, yarn defects, snags,..

Quality through Innovation

Practix Manufacturing's OK-420/425 thermal printing machines for T-shirts, sweatshirts, and finished apparel features a pneumatic cylinder for platen pressure and swing away heated head movement for easy operation and print alignment. The company's OK-375 embossing press with semiautomatic pneumatic fusing frame movement provides heavy du..

Impact of Moisture Content.

In a lecture at the tenth International Wool Textile Researcher Conference, Professor Jens-Holm Dittrich of Hannover University discussed right first time production of batch dyed wook, the absorption properties of powdered dyes, and the effects of moisture content of dyes and substrates on shade. Powdered dyes vary in weight at different..

Modification of PAN Fabrics by In SituPlasma Polymerisation Methods.

Researchers subjected polyacrylonitrile (PAN) fabrics to low temperature acrylic acid, water, and argon plasma treatments to increase their hydrophilicity, soil resistance, and dyeability. Controlling exposure time and discharge power controlled plasma surface modification. Fabrics were dyed with DyStar C.I. Basic Red 18. All three in sit..
