Continuous-filament yarns. The increased bulk may be obtained by the introduction of crimps, coils, loops, or other fine distorsions along the length of the originally straight and parallel filaments. 2: Staple yarns. The increased bulk may be obtained by blending together, during yarn spinning, fibres of high and low potential shrinkage, e.g., high-bulk acrylic yarns. During subsequent hot or wet processing, the greater contraction of the high-shrinkage fibres causes the yarn to contract longitudinally, and the low-shrinkage fibres to buckle, thus increasing the bulkiness of the yarns.
The changed cross-section of the yarn makes it possible to obtain this bulkiness. While the yarn does have some elasticity, it does not seem to be able to cope with the elongation and the recovery of stretch yarn. This term does not include high-bulk yarn.Termes :
