Abstract
A laminate which is elastic in at least one direction, includes an elastic sheet having at least one nonelastic nonwoven web joined thereto at least at two areas. The nonelastic web is gathered between the two areas. The sheet is formed from an aromatic polyetherurethane and the nonelastic nonwoven web includes spunlaced hydraulically entangled polyester fibers. The nonelastic nonwoven web may also include rayon or wood pulp fibers.
Claims22
A laminate which is elastic in at least one direction, said laminate comprising:
- an elastic sheet comprising a polyetherurethane material;
- at least one nonelastic nonwoven web of spunlaced hydraulically entangled polyester fibers joined to said elastic sheet at least at two areas, said nonelastic web being gathered between said two areas.
An elastic stretch-bonded laminate adapted to stretch at least about 50 percent in at least one direction, said laminate comprising:
- an elastic nonwoven web, said elastic web comprising fibers of a polyetherurethane material;
- and
- at least one nonelastic nonwoven web of spunlaced hydraulically entangled polyester fibers joined to said elastic web at least at two areas, said nonelastic web being gathered between said two areas.
An elastic palindromic stretch-bonded laminate adapted to stretch at least about 75 percent in at least one direction, said laminate comprising:
- an inner elastic nonwoven web having a basis weight of from about 20 grams per square meter to about 100 grams per square meter, said elastic web comprising meltblown fibers of a polyetherurethane material having a melt index of from about 5 grams per 10 minutes to about 20 grams per 10 minutes when measured at 190 degrees C. under a 2,160 gram load;
- and
- two outer nonelastic nonwoven webs comprising spunlaced hydraulically entangled polyester fibers, said nonelastic webs each having a basis weight of from about 1 ounce per square yard to about 5 ounces per square yard.
