用丙烯系弹性体制备的纤维和无纺织物
摘要：
一种由组合物制造的无纺织物，其包含(a)丙烯系弹性体，其特征在于包括约5％到约35％重量的衍生自α－烯烃的单元并且由DSC测定的小于80J/g的熔融热，(b)丙烯系热塑性聚合物，其特征在于约3到约300dg/min的MFR(ASTM D－1238 2.16kg@230℃)和由DSC测定的大于80J/g的熔融热，以及(c)触感改性剂，其选自(i)具有超过400dg/min的MFR(ASTM D－1238 2.16kg@230℃)的高MFR热塑性树脂，(ii)烃树脂，(iii)聚烯烃蜡，(iv)官能化烃树脂，(v)官能化聚烯烃，以及(vi)前述触感改性剂的两种或多种的组合，(d)任选的滑动助剂。
摘要（英）：

A nonwoven fabric made from a composition comprising (a) a propylene -based elastomer characterized by including from about 5% to about 35 % by weight units deriving from alpha- olefin and a heat of fusion, as determined by DSC, of less than 80 J/g, (b) a propylene-based thermoplastic polymer characterized by an MFR (ASTM D-1238 2.16 kg @ 23O0C) of from about 3 to about 300 dg/min, and a heat of fusion, as determined by DSC, of greater than 80 J/g, and (c) a feel modifier selected from the group consisting of (i) a high-MFR thermoplastic resin having an MFR (ASTM D-1238 2.16 kg @ 23O0C) in excess of 400 dg/min, (ii) a hydrocarbon resin, (iii) a polyolefin wax, (iv) a functionalized hydrocarbon resin, (v) a functionalized polyolefin, and (vi) a combination of two or more of the foregoing feel modifiers, and (d) optionally a slip aid.
