High-density polyethylene fiber of h.d. polyethylene which satisfies the following condition; (a) density(g/cm3); 0.941-0.960 (b) Q (weight average mol w.t./number average mol. w.t.); below 10.0 (c) melting point; 120-140 deg.C or composite fiber of which above mentioned high density polyethylene fiber forms the outer portion (e.g. sheath side), the core portion is made of polypropylene with the melting point move than 20 deg.C above that of high density polyethylene fiber, and the alignment is pararrel or core-sheath type, is heat-bonded with other fibers to form heat- adhesive nonwoven. |
