Abstract:
A method of manufacturing comingled yarn of carbon and thermofusible fibres comprises the steps of: feeding a tow of thermofusible fibres from a spool to a blending roller and between the spool and the blending roller, spreading the thermofusible tow; feeding a tow of carbon fibres from a spool to the blending roller; spreading the carbon fibre tow between the spool and the blending roller by applying a flow of air over the tow to urge the tow against a supporting surface over which the carbon fibres pass on their way to the blending roller; combining the thermofusible and carbon fibre tows at the blending roller.
Abstract:
Es wird ein Verfahren zur Herstellung eines Bändchengarns offenbart, umfassend die folgenden Schritte: a) Vorlegen eines Garnes aus Multifilamenten auf Basis Polyamid und/oder Polyester, b) Aufspreizen des Garnes, dass nicht mehr als fünf Filamente übereinander liegen, c) Fixieren des Garnes durch Ausbildung einer Matrix aus einem oder mehreren Fixiermitteln, d) Aufwickeln des fixierten Garnes, dadurch gekennzeichnet, dass das oder die Fixiermittel ausgewählt werden aus einer Gruppe bestehend aus Copolyamiden, Copolyestern und Silikonen sowie Mischungen oder Blends daraus. Darüber hinaus betrifft die Erfindung das Bändchengarn und die Anwendung der Bändchengarne für Airbaggewebe, als Reifenverstärkung sowie im textilen Bauen.
Abstract:
Vorgeschlagen wird ein Hybridgarn (1) zur Herstellung von Formteilen (8), welche eine thermoplastische Matrix und darin eingebettete Verstrkungsfasern (4, 5, 6, 7) aufweisen, wobei das Hybridgarn (1) einen Kern (2), der im Wesentlichen aus in einer Längsrichtung (LR) des Hybridgarns (1) geradlinig ausgerichteten Stapelfasern (4, 5) besteht, und einen Mantel (3), der im Wesentlichen aus schraubenlinienformig um den Kern (2) geschlungenen Stapelfasern (6, 7) besteht, umfasst, wobei die den Kern (2) bildenden Stapelfasern (4, 5) und die den Mantel (3) bildenden Stapelfasern (6, 7) jeweils aus einer innigen Mischung (4, 5; 6, 7) von thermoplastischen Matrixfasern (4, 6) und von Verstärkungsfasern (5, 7) bestehen.
Abstract:
A decorative outdoor fabric including a woven structure formed of acrylic warp yarns (10) and at least some of the fill yarns (12) comprising self-coating yarns (14) formed of high melt and low melt yarn constituents. When the fabric is tentered, the low melt constituents melt and cross-flow to the other fibers in the fill (12) and warp yarns (10). Both the warp yarns (10) have deniers in the range of 400-4000 and the fill yarns (12) have deniers in the range of 150-4000. Because of the cross-flow of the low melt constituents, the resulting fabric achieves acceptable abrasion resistance, stability, and load recovery and hand without the need for a latex backing.
Abstract:
Yarn suitable for tufting comprises a base fiber ring spun or wrap spun with a second fiber at least partially comprising a heat-activated adhesive material such that the yarn includes from 0.1 to 12, preferably 0.25 to 10, weight percent adhesive material having a melting point within the range of 105 DEG to 190 DEG C, more preferably 165 DEG to 190 DEG C. A preferred base fiber is a synthetic staple fiber bundle. A preferred wrapping or insert fiber is a copolyamide fiber, including ternary copolyamides of the 6/66/12 type. When the yarn is twist set by conventional processes and then tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.
Abstract:
The present invention relates to a method for manufacturing a three-dimensional textile product, characterised in that at least the pile thread of which is subjected to one or more of the following textile treatments: a) the textile thread is enveloped; b) several textile threads are added to the textile thread; c) the textile thread is structured by making use of at least one monofilament and at least one multifilament; d) the textile thread is structured by making use of at least one monofilament and at least one multifilament thread of thermoplastic fibres; e) each of the textile treatments mentioned in points a - d are performed under such circumstances that the textile thread is kept sufficiently flexible during a first textile treatment and can be stiffened in a subsequent treatment.
Abstract:
Cables structures comprising at least two thermoplastic polymer filaments (10) are prepared in a single extrusion process and exhibit performance characteristics comparable to cabled yarn constructions. The cables can be used in fabrics such as those used in paper manufacture.
Abstract:
A window blind fabric comprises a low melt component and a high melt component and is stabilized by a heat treatment, which comprises heating the fabric to melt only the low melt component. On cooling, the low melt component sets and stabilises the fabric. The fabric suitably comprises a yarn which in itself contains low melt staple fibres or filaments and high melt staple fibres or filaments.
Abstract:
Synthetic yarn comprises a blend of base fiber selected from the group consisting of polyester, nylon-6 and nylon 6,6 and 1-12 weight percent, preferably 1-8 weight percent, of a heat activated binder fiber with a melting point within the range of 110-170 DEG C, preferably 130-160 DEG C. A preferred binder fiber is a copolyamide fiber, including ternary copolyamides of the 6/66/12 type. When the yarn is twisted, plied and twist set by conventional processes and the treated yarn tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.
