Formable stitched together precursor fabric made from weft and warp flat tapes of fiber-reinforced polymer on a weft insertion-stitching machine. The weft tape is supplied from a rotatable or stationary package that is pulled by a tension compensator that is driven in synchronism with an indexing carriage that wraps the tapes around continuously moving weft hooks. A constant tension on the tape is maintained. The weft tapes are stitched to the warp tapes, all in plane tapes having edges that abut substantially throughout the fabric.

A mat for use in a paved surface comprises a nonwoven or woven fibrous mat made from fibers including polymer fibers, the polymer fibers having a melting point greater than about 320null F. (160null C.). The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another mat comprises a nonwoven or woven fibrous mat made from fibers selected from the group consisting of mineral fibers, polymer fibers, natural fibers, and mixtures thereof, and a rubbery binder. Another mat comprises a nonwoven or woven fibrous mat made from a blend of high melt polymer fibers having a melting point of at least 350null F. (177null C.) and low melt polymer fibers having a melting point of less than 350null F. (177null C.).

The invention relates to, in particular, a geotextile comprising linear running warp threads (1) and linear running weft threads (2) which are essentially orthogonal thereto. Said weft threads are joined to the warp threads (1) by means of fixing threads (3) which are applied by warp knitting and whose meshes wrap around the warp threads (1) along the entire length and around the weft threads (2) in the area of crossings (4). The warp threads (1) and the weft threads (2) are arranged individually or in groups in larger intervals which result in inner widths (5) of the mesh (6). The aim of the invention is to attain an improved joining of warp threads and weft threads without requiring the use of additional fixing threads or stronger fixing threads. To this end, the invention provides that, in the areas in which the weft threads (2) cross the warp threads (1), the lengths of the meshes (7) of the fixing threads (3) are distinctly shorter than the lengths in the areas of the mesh structure which are located therebetween.

A stitched pile surface structure and a process and apparatus for producing and finishing the same is disclosed. The stitched pile surface structure includes a backing having a thickness T. A plurality of parallel lines of stitches extends longitudinally along the backing. Each stitch has a predetermined stitch length dimension S. A plurality of rows of pile elements (either as loop pile or cut pile) is formed from one or more pile yarn(s) having an effective predetermined yarn diameter D. The total weight of the yarn used to form the pile loop elements is G grams. Substantially all of the stitches have a thread length DKL that satisfies the relationship: DKL

A warp knitted fabric is disclosed having large grid openings formed by biaxially arranged stay- and weft threads. Also disclosed is a method of making the fabric. The method involves providing stay threads and weft threads which are bound to each other by stitches provided by warp threads. The number of stitches per unit length within a repeat and in the spacing between the crossing areas of the stay- and the weft threads is at least partially smaller than within the crossing areas themselves.

A method of producing of spacial, single or multi-layer knitting articles on a flat knitting machine having at least two needle beds and a loop transfer device, has the steps of knitting of knitting rows with a number and width a corresponding to a spacial structure of a knitting article to be produced and corresponding to material and machine properties, selecting a sequence of the knitting rows so that a maximum possible uniform distribution of the knitting rows of different width and thereby reverse points in a knitting direction over the knitted article is provided, and for each loop row selecting a loop size so that a desired geometrical structure of the knitting article is obtained in an optimal manner.
摘要:
A fibrous sheet for structure reinforcement comprising a sheet layer of reinforcing continuous filament bundles (1) arranged parallelly spaced out from each other, auxiliary covering yarns (3, 4) arranged on both sides of the sheet layer in such a manner that each of the covering yarns intersects respective reinforcing filament bundles (1) while meandering along the longitudinal direction of the reinforcing filament bundles on at least one side of the sheet layer and auxiliary chain-stitching yarns (6) which interconnects the auxiliary covering yarns on one side of the sheet layer with the auxiliary covering yarns on the other side of the sheet layer through individual spaces among adjacent reinforcing filament bundles in a warp knitting structure.
摘要:
An apparatus for the production of knitted goods having integrated weft and/or warp threads, comprising a knitting machine having at least one needle bed, a guide extending along the needle bed in the vicinity of a knitting region of the knitting machine for the controlled movement of a control-actuatable thread carrier independently of a thread guide of a knitting feed system of the knitting machine, a guide carriage of the thread carrier which carriage is movable on the guide, a thread feed member provided on the thread carrier and having a feed region from which at least one thread is fed to the knitting region, and a control for the actuating of the guide carriage of the thread carrier.
摘要:
A filament reinforced perforate composite sheet is manufactured by forming a filament assembly which includes reinforcing filament structures and passage forming filament structures and in which the passage forming filament structures extend from the front face to the rear face of the assembly, applying a matrix material to the assembly to form a composite sheet in which the passage forming filament structures extend from the front face to the rear face of the sheet and removing the passage forming filament structures or a part or parts thereof to produce a multiplicity of passages extending through the composite sheet. The passage forming filament structures may be continuous monofilaments which may be hollow, an assembly of continuous filaments in the form of a tow or twisted together or a yarn spun from short fibers and the material from which they are made is so selected that they can be melted or dissolved out of the sheet or withdrawn in their original state or parts of the hollow monofilaments removed to form the passages through the sheet.
