Abstract: PROBLEM TO BE SOLVED: To improve a balance of feather-like bulkiness, bulk durability, drape performance, flexibility, a slimy feeling and a heat retaining property by forming a core material as a stitch structure by core material fiber, forming a packing material by knitting hair material fiber into the stitch. SOLUTION: A packing material is constituted by knitting hair material fiber 2 into a stitch structure by forming a core material 3 as the stitch structure by core material fiber 1. Slipping-out of hair of the hair material fiber 2 is prevented thereby. The group number of hair material fiber 2 in a single stitch row of the core material fiber 2 is not particularly limited. It may also be constituted as two groups or more by knitting groups of the hair material fiber 2 into another stitch of a single stitch row. The lengthwise direction (the stitch continuing direction) length of this core material 3 is preferably 5 to 100 mm. The projecting length of the hair material fiber 2 is preferably 5 to 50 mm. Therefore, feather-like bulkiness, bulk durability, flexibility, slimy feeling and a heat retaining property can be held in a well-balanced state.

Abstract: PROBLEM TO BE SOLVED: To obtain a soft and spun-toned pile fabric excellent in pile surface covering effect and resistance to pile falling, by using filament yarns as pile yarns which are produced by combining and interlacing two kinds of polyester filaments differing in birefringence from each other followed by false-twist texturing. SOLUTION: Polyester filaments A and B with birefringence of 110 to 150×10 and 20 to 50×10 , respectively, each having a single fiber fineness of 0.5-6 denier, are arranged in parallel with each other in a weight ratio of (35:65) to (65:35) and then interlaced with each other through an interlacing nozzle. The resultant filament yarn is subjected to false-twist texturing process to produce a processed yarn having the following characteristics: the number of false-twists satisfies the relationship: 15,000 =10%. Using the above processed yarn as pile yarn, the objective pile fabric 20-120 counts/cm in pile density is obtained.
