Definitions

  • the end of the fastening tape that does not engage the loops in the landing member area may be attached to one end of an elastic/stretch member (ear), and the other end of the elastic/stretch member may be secured to the longitudinal edge of the body portion of the absorbent article.
  • Tensile Strength refers to the maximum tensile force (Peak Force) a material will sustain before tensile failure, as measured by the Tensile Strength Measurement Method set forth herein.
  • Thermoplastic adhesive material is understood to comprise a polymer composition from which fibers are formed and applied to the superabsorbent material with the intent to immobilize the superabsorbent material in both the dry and wet state.
  • the thermoplastic adhesive material of the present disclosure forms a fibrous network over the superabsorbent material.
  • the substrate 64 of the first absorbent layer 60 may be referred to as a dusting layer and has a first surface 78 which faces the backsheet 20 of the diaper 10 and a second surface 80 which faces the absorbent particulate polymer material 66.
  • the substrate 72 of the second absorbent layer 62 may be referred to as a core cover and has a first surface 82 facing the topsheet 18 of the diaper 10 and a second surface 84 facing the absorbent particulate polymer material 74.
  • the first and second substrates 64 and 72 may be adhered to one another with adhesive about the periphery to form an envelope about the absorbent particulate polymer materials 66 and 74 to hold the absorbent particulate polymer material 66 and 74 within the absorbent core 14.
  • thermoplastic polymers that may be employed are metallocene polyolefins, which are ethylene polymers prepared using single-site or metallocene catalysts. Therein, at least one comonomer can be polymerized with ethylene to make a copolymer, terpolymer or higher order polymer. Also applicable are amorphous polyolefins or amorphous polyalphaolefins (APAO) which are homopolymers, copolymers or terpolymers of C 2 to alpha olefins.
  • metallocene polyolefins which are ethylene polymers prepared using single-site or metallocene catalysts. Therein, at least one comonomer can be polymerized with ethylene to make a copolymer, terpolymer or higher order polymer.
  • APAO amorphous polyolefins or amorphous polyalphaolefins
  • the fastener attachment means 94 is an adhesive applied to the fixed portion of the fastener such that it is offset from each of the edges of the fixed portion that are overlapped by body portion 12, including the edge formed by folding line 70, as is shown in Fig. 6C, as denoted by offsets 100a, 100b, 100c, and lOOd.
  • the adhesive is applied to the fixed portion of the fastener such that it is offset from each of the lateral edges of the fixed portion including the edge formed by the folding line, as is shown in Fig. 6C, as denoted by offsets 100b and lOOd, i.e. 100a and 100c are reduced to zero.
  • Sample A was made by applying a commercially available fastening tape to a diaper stretch ear on a diaper converting line.
  • the tape is 46 mm lateral x 26 mm longitudinal length tape (obtainable from 3M Corporation under the trade name CFT-00104 and related trade names).
  • This tape consists of a nonwoven extrusion laminated to a poly film and contains a pressure sensitive adhesive. In addition to the adhesive attachment, the tape-to-ear bond was augmented with a mechanical bond.
  • the Sample A fastener further comprises a release tape applied with its adhesive side overlapping both the diapers' ear and the fastening tape. This release tape is also obtainable from 3M Corporation under the trade name ERT-1075 and related trade names.
