Estimating the term…
A synthetic polymer yarn comprising a bicomponent yarn and a second yarn combined to form a single yarn is disclosed. The bicomponent yarn is made up from a first component and a second component each comprised of a fiber-forming polymer and each having different shrinkages from the other to effectuate a bulking effect. This differential shrinkage may be obtained, for example, by using different polymers or similar polymers having different relative viscosities. The synthetic polymer yarn of the present invention has advantageously exhibited an improved visual effect, including a stratified effect, which improves the visual composition of products produced using the yarn. Moreover, the fabrics produced from the yarn have improved hand and stretch and recovery.
A fabric, comprising a bicomponent effect yarn formed from a filament bicomponent yarn and a second filament yarn, wherein said bicomponent yarn comprises at least a first component and a second component which each have different shrinkages and are each present in a sufficient amount to give a bulking effect to the bicomponent yarn.
