A method is provided for forming connections from reinforcing fibers between faces of a wall for a pressure container. The reinforcing fibers are gripped by tufting needles and are pushed through the faces, and loops are formed through which support elements are introduced. A corresponding method produces a pressure container.

A polyethylene terephthalate bulked continuous filament is manufactured by steps of melt-spinning, multi-step stretching a polyethylene terephthalate chip and a master batch chip for coloring, passing through a texturing nozzle, cooling, and winding and has an elastic modulus of 1.00E+07 to 5.00E+09Pa at a temperature range of 10° C. to 200° C., the filament being manufactured by steps of melt-spinning a polyethylene terephthalate chip and a master batch chip for coloring, multi-step stretching, passing through a texturing nozzle, cooling, and winding.

A tufted article having a backing material and a plurality of tufts. The plurality of tufts can include cut tufts having first and second tuft portions projecting from a face surface of the backing material. The first and second tuft portions of each cut tuft have respective pile heights relative to the backing material. Each cut tuft also has a backstitch that joins the first and second tuft portions and extends across a portion of a back surface of the backing material. The plurality of tufts includes a plurality of asymmetric cut tufts that have first and second tuft portions with unequal pile heights. Systems and methods for making tufted articles having asymmetric cut tufts are also disclosed.

This invention relates to a washable multi-component magnetic floor mat with a hidden base component. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by magnetic attraction. The magnetic attraction is provided by incorporation of magnetic particles in both the textile and base components. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation. Alignment and deployment of the textile component with the base component in an efficient manner is also described herein.

In a preferred embodiment, there is provided a modified fabric composition, the composition comprising a fabric member and an electroactive member for storing energy, wherein the fabric member comprises a fabric framework defining a deformable plane and a plurality of projections extending at an angle from the plane, and wherein the electroactive member is coupled to at least one of the projections.

A carpet comprising a backing and pile comprising looped or cut tufts of pile yarn attached to and extending from the backing. The pile yarn comprises un-twisted, entangled filaments. The filaments are self-crimped and optionally textured multi-component filaments. A first component of the multi-component filament comprises a first thermoplastic polymer and a second component of the multi-component filaments comprises a second thermoplastic polymer. The first and the second thermoplastic polymer have different yield behavior, whereby the multi-component filaments are self-crimping.

An article can comprise a backing and a plurality of yarns tufted, knitted, or woven through the backing, each yarn defining at least one aesthetic characteristic. The at least one aesthetic characteristic can comprise luster, color, size, physical attribute associated with material type, or texture. At least one yarn of the plurality of yarns can comprise an engineered yarn structure having a first yarn section and a second yarn section. The engineered yarn structure can comprise a transition junction comprises commingled portions of the first and second yarn sections. The transition junction can have a length of less than 1 millimeter. The first section can have a first type of a first aesthetic characteristic of the at least one aesthetic characteristic, and the second section can have a second type of the first aesthetic characteristic that is different from the first type.

A cleaning article. The cleaning article has discrete tufts of tow fibers. The discrete tufts are unequally spaced from adjacent tufts, to provide improved collection and retention of debris from a target surface. The tufts may have a pitch, the pitch decreasing as the longitudinal axis of the cleaning article is approached. The cleaning article may be made by cutting out spaces between tufts from a precursor sheet and attaching the precursor sheet to a carrier sheet. Or the cleaning article may be made by cutting a precursor sheet having tufts into discrete portions. These discrete portions are bonded to a carrier sheet.
