FREMGANGSMAADE TIL FREMSTILLING AF ET IKKE-VAEVET STOF INDEHOLDENDE VARMEKLAEBENDE SAMMENSATTE FIBRE |
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 Mw/Mn 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. |
