Crease-recovery of polyvinyl alcohol fibres
article
Polyvinyl alcohol and cellulose are hydrophilic polymers whose fibres exhibit low crease-recovery. A comparison of their molecular structures, however, shows that the creasing problems and their remedy are entirely different. A fibre made wholly of polyvinyl alcohol has good elastic recovery, but low resistance to hot water. By acetalizing the fibre with formaldehyde, its resistance to hot water is raised, but its crease-recovery falls. When other aldehydes are used, the elasticity of the fibres is usually better, but other essential properties, such as strength and breaking elongation, frequently suffer. It is suggested that, by increasing the stereo-regularity of polyvinyl alcohol, a fibre may acquire enough cohesion to dispense with the aldehyde treatment entirely. Crease-recovery of such a fibre may be expected to remain as high as that of the non-acetalized fibre in present production. © 1962, Taylor & Francis Group, LLC. All rights reserved.
