Description

PVA fibers were subjected after heat treatment to acctalization with formaldehyde (ordinary vinylon), chloracetaldehyde (vinylon C), acetalyl monosulfide (vinylon S), benzaldehyde (vinylon B) and dimethyl nonal (vinylon N) and elastic recovery of elongation of fibers were compared. In the whole range of elongation vinylon S and N show the greatest degree of elasticity. Up to 5% elongation elasticity of vinylon B is also good, but at higher elongation it is worse than that of the ordinary vinylon. In the whole range af elongation vinylon C shows the smallest value of elasticity. For all fibers stretched one has a better elasticity.
