Methods and apparatuses for making elastomeric laminates with elastic strands provided with a spin finish

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

20210307970 · 2021-10-07 ·

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

Methods and apparatuses for making elastomeric laminates with elastic strands

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

HIP-TO-WAIST AND WAIST-TO-CROTCH SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS

The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Hip-to-Waist Silhouette from about 0.8 to about 1.1 and a Product Waist-to-Crotch Silhouette from about 0.8 to about 2.0 to provide for the advantages described above.

Receptacle liner

A receptacle liner for gripping the receptacle and method of making. A liner may be formed by one or more panels including at least one resilient segment extending from a bottom to a top of the liner. The liner segment can be coextruded so that the resilient segment is made from resilient material and other portions of the liner are made from another material that is less resilient. When the liner is placed in a receptacle, the liner can be expanded by resiliently stretching the resilient segment so that the liner may apply a gripping force to the receptacle. The liner can include gusseted side panels. A mouth can be formed as a recess in the top ends of front and rear panels and extend through the gusseted side panels to define handle portions and form apertures in the handle portions that open to the mouth.

By coating an inner surface of a preform, in which at least an inner surface is made of polyester and which has transparency, with a coating layer, which has elongation capacity and water insolubility, the inner surface of the preform is protected against a pressurized liquid by the coating layer when the pressurized liquid is supplied to the preform, and occurrence of cloudiness on an inner surface of a container after molding is prevented even in a case where a liquid having properties of eroding polyester and causing cloudiness on a polyester surface is used as the pressurized liquid during liquid blow molding.

PRODUCTION OF MOLDED BODIES FROM AN INORGANIC-ORGANIC HYBRID POLYMER WITH HIGH RESOLUTION USING 3D PRINTING, MOLDED BODIES WITH A HIGH FLEXURAL STRENGTH AND ELASTIC MODULUS, AND THE USE THEREOF FOR DENTAL PURPOSES

The invention relates to a method for producing a shaped body by means of a radiation-induced printing process according to the technique of the one-photon polymerization process, characterized in that the shaped body is produced by solidifying a liquid or viscous material which contains a polysiloxane component produced by hydrolytic condensation of one or more monomeric silanes having exclusively two or three hydrolyzable groups and at least one organically polymerizable radical being bonded to the silicon atom via carbon, and contains an initiator and/or catalyst for the radiation-induced polymerization of the organically polymerizable residue, and the solidification is effected by directing light onto a region of a surface of a substrate, whereby a layer of the material located there is polymerized and thereby solidified, whereupon further layers are successively solidified.

Furthermore, the invention relates to a shaped body based on an organically polymerized silica (hetero)polycondensate, which was produced by organic polymerization of the aforementioned polysiloxane component, with superior mechanical properties.
