PURPOSE:To obtain the title nonwoven fabric having high mechanical strength for tension in all directions by spirally arranging specific conjugate monofilaments on thermofusible conjugate fiber-contg. nonwoven fabric followed by thermofusing. CONSTITUTION:(I) Conjugate filaments >=100 denier in fineness with a single fiber tenacity of >=2g/de and thermal shrinkage rate of <=15% at 150 deg.C, either of sheath-core type made up of (A) a higher-melting component as core and (B) a lower-melting component as sheath, or of side-by-side type made up of the components A and B at the conjugate ratio of (30:70) to (60:40) are spirally arranged in blocks of random size at a density of >=200m/m<2> on (II) a nonwoven fabric (or web) containing >=30wt.% of thermofusible conjugate fibers, followed by bonding of the filaments to the nonwoven fabric through thermofusing, thus obtaining the objective nonwoven fabric reinforced with conjugate monofilament bundles. |
