Abstract: PURPOSE:To obtain a false twisted spun yarn having a high tenacity without slipping off of fibers, by vibrating a fibrous bundle in a false twisted state with ballooning. CONSTITUTION:A staple fibrous bundle in an opened state delivered from a drafting zone is false twisted by a false twisting apparatus 8, and staple groups in the central part of the bundle are mainly changed into a false twisted state. At least one end of fibers in at least part of staple fiber groups in the peripheral part of the fibrous bundle is made into an unrestricted state to give a false twisted spun yarn in which peripheral staple fibers each having at least one end in an unrestricted state are wound around the fibrous bundle in a false twisted state. In the process, the fibrous bundle 4 in a false twisted state is vibrated by ballooning with friction false twisting pegs 12 and 12'. According to the method, the spinning step is stabilized and the yarn unevenness, particularly variation coefficient of tenacity, is greatly reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a filter which can keep filtering performance for a long time while highly efficient filtering performance is held. SOLUTION: This filter is characterized by a fiber structural body whose density is 0.01-0.1 g/cm3 and in which fibers are partially stuck together and in which majority of the constitutional fibers of the fiber structural body is arranged so as to make the fiber axial directions approximately in parallel to the direction of one cross-section (abcd) of the fiber structural body and to make them arrange in the random direction within the cross-section, and the cross-section (abcd) is arranged in the passing direction of fluid.

Abstract: PROBLEM TO BE SOLVED: To provide a wiping instrument provided with a stain wiping property, durability, a draining property after use and a drying property, etc. SOLUTION: This wiping instrument is a fiber aggregate whose density is 0.01-0.10 g/cm3 for which fibers are partially adhered to each other. A rugged part is formed on at least a part of the surface of the fiber aggregate and the difference of the height between the recessed part and the projected part adjacent to each other of the rugged part is 0.5 cm or more.

Abstract: PURPOSE:To obtain a bound spun yarn or a composite yarn restrained to the extent not deteriorating the thermal shrinkage characteristics or elasticity characteristics of filaments, and to prevent the breakage of the yarn from generating in a twisting operation or in spinning and weaving operations. CONSTITUTION:The composite yarn is formed so that the end of a binding single filament on spun yarns is positioned in the direction reverse to the transferring direction, when two or more spun yarns 11a, 12a are paralleled into a doubled yarn 14 and when the doubled yarn is transferred, the spun yarns 11a, 12a being formed by winding at least one single filament 13 on single filament bundles which substantially forms the cores of the spun yarns and is composed mostly of parallel bundles.
