Sizing Polymer Compositions on the Base of Starch and Polyvinyl Alcohol

Viscosity characteristics compositions based on PAA, PVS and NA-CMS

“…The component composition of the dressing compositions varied in such a way that it was possible to distinguish the effect of the recommended components both on each individual component and on their various combinations and ratios [4].…”

“…Despite the low relative viscosity and degree of polymerization of starch, dextrinized paste (as well as ordinary starch) is highly structured in comparison with the developed one. The established phenomenon of high structuring of starch hydrogels is well known from the literature [2,3]. As is known, the structure of starch paste consists of supramolecular formations (globules, colloidal particles, conglomerates) in which starch macromolecules are involved in intra-and intermolecular hydrogen bonds.…”

“…In order to ensure the elasticity and flexibility of the dressing film formed on the surface of the yarn, as well as its deeper penetration into the yarn, in addition to starch and PVS, hydrolyzed polyacrylonitrile (HYPAN) in an amount of 0.1-0.2% was introduced into the composition of the dressing composition. The starch content varied in the range from 4 to 6%, which is characteristic of compositions for dressing cotton yarn with a linear density of 29.4 text [1][2][3].…”

Physical And Mechanical Indicators Of Yarn Sized With Water-Soluble Polymer Compositions

“…Since the sizing of yarn is the main important and necessary step in the refinement of cotton fibers and yarn based on them. Existing chemical reagents that are used as a sizing ingredient must meet a set of requirements, however, as can be seen from practice, none of the numerous sizing preparations based on natural and synthetic water-soluble polymers fully meets these requirements [1][2][3][4][5].…”
