An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of an applicator mitt to be cut; a heating element associated with the tooling body, the heating element being shaped so as to match or substantially match a shape of the weld bead so as to create a perimeter weld for the applicator mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt away from the tooling body. The system can further comprise a conveyor device adapted to feed uncut and unwelded mitt material towards the applicator mitt tooling and a tooling actuator adapted to actuate the applicator mitt tooling relative to the conveyor device.

APPARATUS AND METHOD FOR VOLUMETRIC REDUCTION OF POLYMERIC MATERIAL
20190016033 · 2019-01-17 ·

The present invention is an apparatus and method for volumetric reduction of polymeric material and in particular synthetic polymeric textile materials. Such materials are typically used in hospital operating rooms and have material memory meaning that they re-expand after compression. Consequently they are difficult to process as waste material. The present invention is a method and apparatus for thermally compacting a polymer comprising a first and second heated surface inclined downwardly towards each other and providing with a passage at their lower ends through which melted polymeric material may pass.

C., residence time of less than 2 min and the polyethylene-based composition is in the presence of at least one free radical generator.

METHOD AND EXTRUSION DIE FOR MAKING A STRUCTURING FABRIC

An extrusion die makes a structuring fabric which has structuring-beads resting on sublayer-beads. The extrusion die has a flat first surface and a flat second surface, the first and second surfaces contact each other along a contact line. The first and second surfaces are inclined with respect to each other. The first surface has a first nozzle of a pair of nozzles for extruding a sublayer-bead and the second surface has a second nozzle of the pair of nozzles for extruding a structuring-bead on top of the sublayer-bead. The first nozzle has a substantially rectangular shape and the second nozzle has a shape that resembles a square with all four side edges bulged inwardly. Both the first nozzle and the second nozzle are located in close proximity to the contact line. The first nozzle has a first symmetry axis that is perpendicular to the contact line.

10155342 · 2018-12-18 · ·

A seaming element for seaming industrial textiles for filtration or other uses, an industrial textile with seaming elements, and a method of seaming such textiles. The seaming element is secured to a first seamable end or edge of the fabric, and includes at least one extension member, which can be a channelled protrusion, and which is engageable with a corresponding at least one extension member of a corresponding seaming element secured to the second seamable end or edge. The seaming elements are configured and dimensioned so that when the extensions or protrusions of the two seaming elements are aligned together and engaged, in some embodiments being secured by a pintle, they have a thickness which is compatible with the caliper of the finished fabric, to form a secure seam while avoiding or minimizing any discontinuity or irregularity in the finished fabric.

Fabricating method for meltblown nonwoven from natural cellulose fiber blended with nano silver

The present invention provides a fabricating method for meltblown nonwoven from natural cellulose fiber blended with nano silver, which comprises following steps. Firstly, prepare nano silver colloidal sol by reduction titration for mixture of polyvinyl alcohol (PVA), silver nitrate (AgNO.sub.3) and sodium borohydride (NaBH.sub.4). Secondly, prepare mixing cellulose serum by blending agitation for mixture of wood pulp, N-methylmorpholine N-oxide (NMMO) and stabilizer. Thirdly, prepare blending mucilage from mixing cellulose serum via blending process. Fourthly, produce spinning dope by blending and dehydrating the nano silver colloidal sol and mixing cellulose serum. Fifthly, produce molten filament tow by meltblown spinning method in association with coagulation, regeneration in coagulation bath, and water rinse. Finally, by post treatments of hydro-entangled needle punching, drying, winding-up processes in proper order, obtain final product of meltblown nonwoven from natural cellulose fiber blended with nano silver, which is biodegradable with features of antibacterial and antistatic capabilities.

Article assembly disassembly system

There is described a system, article, method, connectors and apparatus for article reuse or recycling, which system including the assembling of an article from at least two components at least one of which has a textile material brought into communication with each other through one or more connectors and the subsequent disassembling of the article and use of one or more of the components in the assembling stage. The assembled article is susceptible to automatic or semi-automatic disassembly through one or more of its connectors being susceptible to a reduction in one or more mechanical properties under exposure of the article to electromagnetic energy especially microwave. The article may be a garment that has joins stitched with a microwave susceptible yarn. The yarn is ideally manufactured from pseudo-conductive materials and is metal free.

MANUFACTURING APPARATUS AND MANUFACTURING METHOD FOR THREE-DIMENSIONAL OBJECT AND THREE-DIMENSIONAL OBJECT
20180264740 · 2018-09-20 · ·

A three-dimensional object manufacturing apparatus has an input receiver, a three-dimensional shaping information generator, and a shaping part. The input receiver has a yarn-related information receiver that receives information inputted of a yarn, and a weaving method receiver that receives information inputted of a weaving method for the yarn. The three-dimensional shaping information generator generates three-dimensional shaping information of the three-dimensional object based on the yarn-related information and the information of the yarn weaving method. The shaping part forms the three-dimensional object on a working plane by ejecting an object forming material onto the working plane and curing the ejected material based on the three-dimensional shaping information.
