Abstract

An elastic pad 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 may be formed from a polyetherester and the nonelastic nonwoven web may be a web of spunlaced hydraulically entangled polyester fibers. The nonelastic nonwoven web may also include rayon or wood pulp fibers.

Independent Claims | See all claims (49)

  1. 1. An elastic pad formed from a composite elastic laminate which includes an elastic nonwoven web and at least one nonelastic web joined to said elastic nonwoven web at least at two areas and with said nonelastic web being gathered between said two areas, said pad comprisinga top; andsides depending from said; andwherein said sides are adapted to retainingly engage an edge of a surface to be covered.
  2. 6. An elastic pad formed from a composite elastic laminate which includes an elastic nonwoven web and at least one nonelastic web joined to said elastic nonwoven web at least at two areas and with said nonelastic web being gathered between said two areas, said pad comprising:a top; andsides depending from said top; andwherein said sides are adapted to retainingly engage an edge of a surface to be covered.
  3. 12. An elastic pad comprising:a top; andsides depending from said top that are adapted to retainingly engage an edge of a surface to be covered; andwherein said elastic pad is formed from a stretch-bonded laminate; includingan elastic nonwoven web, said elastic web comprising fibers of a polyetherurethane material; andat 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.
  4. 13. An elastic pad comprising:a top; andsides depending from said top that are adapted to retainingly engage an edge of a surface to be covered; andwherein said elastic pad is formed from a stretch-bonded laminate, said laminate including:an elastic nonwoven web, said elastic web comprising fibers of a polyetherester material having the formula of; ##STR3## where "G" is selected from the group including: poly(oxyethylene)-alpha, omega-diol poly(oxypropylene)-alpha, omega-diol poly(oxytetramethylene)-alpha, omega-diol and "a", "m" and "n" are positive integers; andat least one nonelastic nonwoven web of spunlaced hydraulically entangled polyester fibers joined to said elastic web at least at two areas and with said nonelastic web being gathered between said two areas.
  5. 21. An elastic pad comprising:a top; andsides depending from said top that are adapted to retainingly engage an edge of a surface to be covered; andwherein said elastic pad is formed from a palindromic stretch-bonded laminate, said laminate including: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 polyetheresterurethane 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; andtwo 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.
  6. 22. An elastic pad comprising:a top; andsides depending from said top that are adapted to retainingly engage an edge of a surface to be covered; andwherein said elastic pad is formed from a palindromic stretch-bonded laminate including: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 polyetherester material having the formula of: ##STR4## where "G" is selected from the group including: poly(oxyethylene)-alpha, omega-diol poly(oxypropylene)-alpha, omega-diol poly(oxytetramethylene)-alpha, omega-diol and "a", "m" and "n" are positive integers; andtwo 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.
