SUBSTRATE WITH DEPOSITION AND/OR FRICTION REDUCTION COATING
The present disclosure may be directed towards a substrate with an array disposed thereon. The substrate comprising a bonding array with a plurality of bonding locations. A low emissivity layer is deposited on at least one side of the substrate and covers at least some of the bonding locations. The low emissivity layer may be a metal layer which functions as a radiant barrier.
Elastomeric Laminate
Methods and (articles of manufacture therefrom) including forming an elastic film from a polymer composition; tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD; laminating the elastic film to an extensible facing to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less.
POLYOLEFIN-BASED MULTILAYER ELASTIC FILMS
According to at least one embodiment of the present disclosure, a multilayer elastic film comprises a core layer, a first outer layer, and a second outer layer. The core layer comprises at least 75 wt % polyolefin elastomer such as an ethylene/alpha-olefin block copolymer or a propylene-based plastomer. The first outer layer and the second outer layer each comprise at least 75 wt % of an ethylene-based copolymer, wherein the ethylene-based copolymer is selected from the group consisting of: (I) greater than 50 wt % of ethylene, from 5 to 16 wt % of an α,β-ethylenically unsaturated C3-C8 carboxylic acid, and optionally, from 0.5 to 10 wt % of an alkyl acrylate; (II) from 86 to 95 wt % of ethylene, and from 5 to 14 wt % of an alkyl acrylate; and (III) combinations thereof.
Methods of making laminates for absorbent articles
A method of making a laminate for an absorbent article is provided. The laminate comprises elastic elements disposed at least partially intermediate two substrates. The first substrate has a primary fiber bond pattern formed therein and comprising a plurality of primary fiber bonds. The method comprises forming densified regions in the first substrate. A perimeter of each of the densified regions is larger than a perimeter of each of the primary fiber bonds. The densified regions together form a pattern of densified regions in the first substrate. The method comprises adhesively attaching the elastic elements to the first substrate, joining the second substrate to the first substrate or to some of the elastic elements, and forming a plurality of rugosities in the first substrate by allowing the elastic elements to at least partially contract. The frequency and amplitude ranges of the rugosities result from the pattern of the densified regions.
PROTECTIVE GARMENT
A protective garment, gussets for protective garments, and individual gusset layers, being a moisture wicking layer, a core moisture absorbing layer and a moisture impermeable layer, and combinations thereof. The moisture wicking layer including a double knit fabric wherein a technical face of the fabric forms an eyelet mesh utilising both hydrophilic and hydrophobic yarns and a technical back of the fabric forms an interlock utilising only hydrophilic yarns. The moisture absorbing layer including a sinker terry fabric knit comprising sinker loops with plush loops made form synthetic fibres treated with a hydrolysing enzyme that splits the fibres into fibrils. The moisture impermeable layer including a base fabric knit laminated with a polyurethane sheet.
Elastic film and method for producing an elastic layer material
An elastic film has a perforation formed by perforation holes that are elongated along a preferred expanding direction in the unexpanded state, wherein the ratio of the length of the perforation holes determined along the preferred expanding direction to a width of the perforation holes determined perpendicular thereto amounts to at least 3:2. The elongation at break along the preferred expanding direction is at least twice as high as the elongation at break determined perpendicular thereto along the width of the perforation holes.
Garment incorporating aqueous polyurethane dispersions having altered stress profile
Articles, such as garments, including films comprising dried aqueous polyurethane dispersions are disclosed, whereby the garment has an altered stress which is exhibited during wear of the garment. The film may be bonded to the fabric of the article to provide a fabric or film laminate.
Stretchable film and article comprising same
Provided is a stretchable film having excellent stretchability, excellent air permeability, and an excellent deodorizing property. Also provided is an article including such stretchable film. A stretchable film of the present invention is a film having stretchability, and includes a deodorant. The stretchable film of the present invention is a film having stretchability, and has a deodorization efficiency for each of ammonia and hydrogen sulfide 3 hours after the start of a deodorization test, the deodorization efficiency being measured by a detector tube method, of 10% or more.
Method and apparatus for assembling absorbent articles
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.
Patterned apertured webs
A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.
