摘要:
An embossing and texturizing system capable of imparting a natural cloth-like surface to a flexible thermoplastic material or film simultaneously to either or both of its two exterior surfaces, through the use of a unique device and technique combining metal rolls, metal and rubber rolls, and embossing and texturizing fabric rolls into an embossing system creating the desired visual and tactile feel of natural fabrics as well as additional performance characteristics. The embossing and texturizing system embosses and texturizes the exterior surface of the flexible thermoplastic material or film by selectively altering the exterior surface, and therefore, the film can be embossed simultaneously on either or both of its two exterior surfaces (face and reverse) without necessitating major interruption or adjustment of the system. The use of the embossing and texturizing mechanism and its alignment to the core and stabilizing reinforcing substrate enables the exterior texturized surface and the bottom side exterior texturized surface to be identical in all manner.

A method of making a mechanical fastening net. The method includes providing a net having strands of polymer and open areas between the strands of polymer and molding a portion of the polymer in the strands of the net into upstanding posts to form the mechanical fastening net. A mechanical fastening net that includes a polymeric backing, a plurality of openings in the polymeric backing, and upstanding posts on at least one of the first or second major surface of the polymeric backing is also disclosed. The polymeric backing has a range of thicknesses ranging from minimum to maximum thickness, and for at least a portion of the polymeric backing, the minimum thickness of the polymeric backing is where it abuts one of the openings.

Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.

Furthermore, the invention relates to a method and a device for producing such an embossing roll for continuous embossing of nanostructures as well as a method for producing such a nanostructure die and a method for producing an embossing substrate.
摘要:
A molding roller includes a cylindrical main body and a seamless ring-shaped molding film. The main body has a circumferential surface. The molding film is directly formed on the circumferential surface. The molding film has a molding surface including a number of molding patterns. The molding film is made of polymer resin consisting of polydimethylsiloxane and a plurality of silica nanoparticles formed in polymer grids of the polydimethylsiloxane.
摘要:
Systems and methods for forming a vacuum formed, apertured film with micro-aberrations may be disclosed. For example, a polymer web such as a molten polymer web may be received at an engagement point between a screen with a positive aberration and a roller comprising a surface with a negative depression. The roller may have a diameter of no more than about 5.5 inches. A micro-aberration may be expanded, for example, on a land of the polymer web at the engagement point by inserting the positive aberration on the screen into the negative depression on the surface of the roller at a pressure of about 1.5 to about 3.5 pounds per linear inch (PLI). Additionally, one or more apertures are formed in the polymer web adjacent to a micro-aberration on a land.
摘要:
An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.
