Solvent texturing experiments are described using partially oriented polyester yarn treated in sequential steps of twisting, solvent setting, and untwisting. Effects of several parameters such as solvent treatment time, pre-immersion solvent, and dra

Solvent-treated polyester is easily penetrated by nonionic fluorescent dye from an aqueous bath. Direct dyes exhaust onto the treated fiber from an aqueous solution containing salt, and the dried, dyed fiber is fast to aqueous washing. Low molecular

Whén poly(ethylene terephthalate) films arc crystallized by certain liquids, thin films exhibit abnormally low densities, in contrast to thick films which have the densities of semicrystalline polymer. Cavitation produced by the crystallizing liquid

PET can be prepared by solvent and heat treatment in widely differing structures as shown by the sorption and transport properties. The order of elution of a pair of solutes on poly(ethylene terephthalate) fibers as chromatographic substrate can be r

The nature of the yellow color that accompanies the degradation of sugars was investigated by studying the spectral characteristics of the tail-end absorption of yellow samples of 5-(hydroxymethyl)-2-furaldehyde (HMF) and 2-furaldehyde. The spectra o

Peracetic acid can be catalyzed to bleach cotton fibers at temperatures as low as 30°C by incorporating 2,2î-bipyridine in the bleach solution if the appropriate concentration of ferrous ions is present in the cotton fibers. The tris-2,2î-bipyridi

Peracetic acid can be catalyzed to bleach cotton fibers at temperatures as low as 30°C by incorporating 2,2î-bipyridine in the bleach solution. Treatment of the fibers with HCl prior to bleaching reduces bleaching effectiveness by removing trace tr

Cellulosic fibers were bleached in perchloroethylene using small quantities of a solubilized mixture of peroxide and water. The diffusion coefficient of solubilized peroxide into cellulose was about equal to that of solubilized water. In contrast to

Amorphous unoriented poly(ethylene terephthalate) was crystallized at 25°C by various organic liquids. The crystalliznity induced in the amorphous polymer was measured by differential scanning calorimetry and infrared spectroscopy. The ability of li

In the previous paper the preparation and properties of fibers containing both polyacrylonitrile and cellulose acetate were discussed. It has proved possible to hydrolyze the cellulose acetate without extensive side reactions to produce fibers contai
