摘要： A tobacco filter stock capable of being molded into a filter only be entanglement of filaments with one another without any adhesion means, whereby the resulting filter has a suitable hardness and a superior whiteness. A tobacco filter and a production process thereof are provided, whereby the tobacco filter stock comprises a ton of crystalline polyolefin filaments, preferably crystalline polypropylene filaments, having a single filament denier of 1 to 6 d/f, a total denier of 30,000 to 60,000 D 40 to 60 crimps/25 mm filament, a crimp elastic modulus of 2.5 to 5.0, a frictional coefficient between filaments of 0.20 to 0.37 and a height ratio (height/width) of 0.01 to 0.1.

摘要： A process for producing a highly bulky nonwoven fabric is provided, which process comprises melt-spinning a crystalline propylene polymer as a first component and an ethylene polymer as a second component, into side-by-side or sheath-core type composite fibers so that the first component after melt-spinning can have a specified M.sub.w /M.sub.n value; collecting the fibers into a continuous tow form; stretching the tow in a specified stretch ratio; cooling the stretched tow to a specified temperature and then drawing it by a pair of nip rolls, one or both of which are of a non-metal, to obtain heat-adhesive composite fibers having apparent crimps of a specified number, a specified percentage crimp modulus and substantially no latent crimpability; and heat-treating a web consisting of the fibers alone or a blend thereof with other fibers at a specified temperature.
