The invention relates to a laminate comprising at least one support element in the form of a non-woven fabric selected from the group consisting of an SM (Spunbond-Meltblown), an SMS (Spunbond-Meltblown-Spunbond), an SMMS (Spunbond-Meltblown-Meltblown-Spunbond), and an SSMMS (Spunbond-Spunbond-Meltblown-Meltblown-Spunbond), having a lower face and an upper face, and at least one non-woven fabric with loops made of a material comprising synthetic thermoplastic polymers, having a lower face and an upper face. The upper face of the support element is secured to the lower face of the non-woven fabric with loops. The curve representing the force required to stretch the laminate along a given axis of the laminate, as a function of elongation, includes a segment in which, starting from a zero elongation value, the force increases from zero up to a maximum force, where the maximum force corresponds to the rupture of the laminate, and the curve comprises an inflection point (Pi) on the segment.

Method for providing a laminate with a hook and loop fastening volume, and resulting laminate

A non-woven sheet () comprises at least one zone of reinforcement () in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern () comprising a plurality of geometric shapes (), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X), and over a width (l, l) strictly less than the width (l) of the sheet () measured in a lateral direction (Y) orthogonal to the longitudinal direction (X). The sheet () thus further comprises at least one non-reinforced zone (). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone () under the effect of a given force exerted in a longitudinal direction of the sheet () is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet () may be used in particular for fabricating a laminated assembly.

Reinforced non-woven fabric, assembly including such a fabric, and method for treating a non-woven fabric

A laminated assembly extends in a longitudinal direction and a lateral direction orthogonal to the longitudinal direction, the assembly including a non-woven sheet and an elastic film that are laminated together, the non-woven sheet including at least one activated zone extending over the length of the non-woven sheet measured in the longitudinal direction and over a width that is strictly less than the width of the non-woven sheet measured in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction being different from the degree of activation of the elastic film in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction lying in the range 20% to 200%.

Laminated assembly and manufacturing method

The invention relates to a laminate () comprising at least one support element (), for example a nonwoven fabric, in particular an SMS nonwoven, and at least one nonwoven loop fabric (), in particular a carded nonwoven, secured to the support element (), in particular by means of calendaring with the first nonwoven fabric, characterised in that the curve representing the force required to stretch the laminate along a given axis (e.g. the MD axis or the CD axis of the laminate) as a function of elongation, comprises a segment in which, starting from a zero elongation value, the force increases from zero up to a maximum force, corresponding in particular to the rupture of the laminate, and the curve comprises an inflection point (Pi) on said segment.

The invention relates to a workpiece having a shape produced by thermoforming from at least one sheet () of plastic material, such as polycarbonate, and at least one applied element () that is applied to the at least one sheet and secured there, characterised in that the securing of the at least one applied element to the at least one sheet takes place at least partially by means of crimping.

The invention relates to a strip or lap comprising loops, in the form of a laminate with printed patterns. The laminate for forming a loop strip or lap, in particular the landing zone of nappies, includes at least one nonwoven layer having a lower face and an upper face opposite the lower face; at least one layer of ink applied to the upper face of at least the nonwoven layer; and at least one external textile layer from which loops project externally in order to engage with hooks of a self-fastening hook and loop device, at least one textile layer being secured to the upper face of at least the nonwoven layer.
