E.L-Sayed Mohamed. El-sayed. Mansour

The dyeing properties of four substituted azopyrazolin-5-one dyes were investigated. The diffusion and fastness properties correlated with the structure of the dyes. Disperse dyes are used principally for the dyeing of secondary cellulose acetate, nylon and polyester fibers. Of these , we are concerned with the polyamide type. Interest has been shown recently in the development of azo dyes from ... [Show full abstract] heterocyclic amino compounds. The principle reason is brilliance of the colour produced. In the present study four new azo disperse dyes suitable or Nylon 6,6 were synthesised, using 3-methyl-1-phenyl pyrazoline-5-one, Some of the dyes gave bright dyeing of good fastness to light, washing, water, perspiration ,dry cleaning, rubbing and sublimation.

Alternatives to Water in Textile Processing

October 2008 · Review of Progress in Coloration and Related Topics

J. K. Skelly

Attempts have been made to correlate the use of organic solvents as alternatives to water in textile processing with the ‘solubility parameter’ concept. Chlorinated hydrocarbons prove suitable for scouring and some finishing operations since their solubility parameters are ideal for such operations. In dyeing, however, the solubility parameter of polyester fibres, dyes and perchloroethylene are ... [Show full abstract] very similar, resulting in poor exhaustion of conventional disperse dyes. New solvent dyeing systems and new dyes, with high partition coefficients in polyester fibres, must be developed for solvent dyeing to become of practical consideration. Other solvents have been examined for solvent assisted dyeing. It has been shown that when benzyl alcohol and 2-phenoxy ethanol are used in dyebaths at concentrations at which these solvents are not completely in solution, both the rate of dyeing and penetration of dye into the fibre can be markedly increased in comparison to normal aqueous dyeing with polyester, nylon and acrylic fibres.

Changes in Tensile Strength and Stiffness of Selected Durable Nonwoven Fabrics due to Abrasion and L...

January 1985 · Journal of the Korean Society of Clothing and Textiles

This research explored the effects of abrasion, laundering, and abrasion/laundering interaction upon wear of 15 durable nonwoven fabrics. Wear was measured in terms of changes in tensile strength and stiffness. The test materials consisted of nine different dry-laid commercial interfacing fabrics of various fiber contents and six spunbonded poyester and polypropylene fabrics. Three fixed levels ... [Show full abstract] of abrasion and four fixed levels of laundering made up the 34 factorial analysis used for the experiment and the analysis of variance. Findings revealed that abrasion had a greater effect than laundering on strength and stiffness of the tested fabrics. Laundering seemed related to the particular fibers used and to the fixation quality of fiber bonds. Spunbonded webs performed better than dry-laid webs in retaining tensile strength Stiffness change occurred more readily than strength change. Lighter, flexible, stretchable fabrics seemed less easily abraded than heavier, stiff, less stretchable fabrics. The interfacing fabrics of 70/20/ nylon/polyester/rayon blends with high crosswise stretchability effectively resisted wear caused by abrasion and laundering. Further research is recommended to study the effects of longer abrasion periods and additional laundering cycles o,1 wear qualities of nonwoven fabrics. Additional factors such as amount and fixation methods of bonding agents, the effect of shear distortion, seam construction, and drycleaning solvents could also be studied.

[Show full abstract] features can obtain using plastination. We aimed to obtain real, reusable, safe and demonstrative anatomical training materials to facilitate cross-sectional anatomy training. The final products should be thin, semi-flexible, translucent and durable. Materials and Methods: A specific sheet plastination procedure with a different surface cleaning method is taking place in this study. Foot and hand slices of 2-3 mm were plastinated with xylene added silicone resin to obtain thin, translucent, semi-flexible and durable slices. Results: The plastinated slices have fine details of many anatomical structures comparable with radiological images. Translucent feature of the sheets provides useful backlit imaging. Sheets are semi-flexible and durable enough to use safely in practices. Conclusion: Plastination seems to be the ideal method for preparing and preserving cross-sectional specimens. We believe that silicone plastinated sheets are useful materials for laboratories that do not have adequate equipment or experience to make epoxy or polyester sheet plastinates.

Development of High Cotton-Content Fire-Retardant Fabrics for Navy Protective Clothing

August 1992

George F. Ruppenicker

Research was conducted to develop chambray, and 2/1-twill, work- uniform fabrics that could be adequately treated for fire retardancy and durable press, and still retain acceptable strength properties. Past attempts in combining the two finishes had resulted in a problem of substantial decreases in both the breaking and tearing strengths of 100% cotton fabrics. The problem was particularly acute ... [Show full abstract] in the filling direction. In an effect to overcome the problem, fabrics were designed and woven using 100% cotton ring-spun warps and cotton/nylon and cotton/polyester filament-core filling yarns. Fabrics containing various intimate blends of cotton and Kevlar staple in both warp and filling were also produced. The cotton/Kevlar blend provided the best approach to producing combination fire-resistant and durable-press shirting fabrics with acceptable tensile properties. Blend fabrics containing at least one-third Kevlar generally met the requirement of both breaking and tearing strengths. The fabrics produced with filament-core yarns, although they showed improved strength in the filling direction, had significant losses in the warp direction (due to 100% cotton warps) after durable-press finishing, indicating that it would be difficult to design a shirting fabric with this technique that would meet both strength and weight specifications.
