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.

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 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.

A system for fastening a covering on a surface includes a first assembly comprising a first retaining element; and a second assembly comprising a second retaining element; the first and second retaining elements being configured to engage each other so as to form a reversible bond; the system being characterized in that the first retaining element comprises an array of retaining elements comprising hooks having a height (Hc) lying in the range 0.05 mm (0.0020 in) to 1 mm (0.039 in), and the second retaining element comprises an array of retaining elements comprising loops having a height (Hb) lying in the range 0.1 mm (0.0039 in) to 3.0 mm (0.12 in).

Attachment system, E.G., for panels

The invention relates to a resilient laminate comprising, in a vertical direction, a stack of at least one nonwoven layer and a ply consisting of a part or integral part attached to the at least one nonwoven layer, in particular by means of an adhesive such as glue, the ply comprising at least one resilient film area and at least one so-called rigid film area made of a material that is less resilient than the material of the resilient area, in particular an area made of a non-resilient material, the ply being produced by the coextrusion of the at least one resilient film and the at least one rigid film, such that an interface is formed therebetween, characterized in that, from a cross-sectional view, the curve or line formed by the interface between the two films comprises at least one first substantially rectilinear segment, and at least one second substantially rectilinear segment which is angled relative to the at least one first segment. The curve or line formed by the interface between the two films extends from a point (P) on the lower face of the laminate to a point (P) on the upper face of the laminate, said points being horizontally offset in relation to one another and the diagonal line passing through said two points being inclined in relation to the vertical to the laminate.
