Abstract:
A flooring article (100) is provided, having a rubber or polymeric backing layer (80) and a textile upper surface, whose pile is comprised of combination yarns (40) in which a monofilament yarn (10) is intertwined with other fibers (12) before being incorporated with a plurality of other yarn plies (22). The monofilaments (10) provide scraping functionality to the flooring article (100) and are secured within the mat structure by being entwined with other fibers (12) before twisting with other yarn plies (22). Preferably, the fibers (12) that are not monofilaments are made of cotton for improved absorbency.
Abstract:
The invention relates to a thread consisting of at least two continuous strands of carbon fibre that are twisted around one another, the carbon fibres of the strands running approximately parallel to the thread direction. The invention also relates to a thread consisting of at least two continuous strands of carbon fibre that are twisted around one another, which is produced by direct cabling. The invention further relates to a method for the production of a thread of this type, according to which at least two strands consisting of continuous carbon fibres are twisted around one another by direct cabling. In said method the assembly eyelet is configured by an eyelet with a radius of at least 4 mm in the area of contact between the strands and the assembly eyelet. The inventive thread is preferably used as sewing thread or thread for reinforcing polymers, elastomers, rubber or concrete.
Abstract:
The invention relates to a device and method for producing an automatically twisted yarn (1), wherein at least two roves (2, 3) are initially guided between at least one false twisting device (4); the roves (2,3) are periodically and alternately provided with areas consisting of S and Z shaped twists which are separated from each other by areas devoid of twists (0), and the roves (2, 3) are subsequently combined in such a way that they become automatically twisted as a result of their own twists; the areas devoid of twists (0) are provided with a phase difference ( phi in the automatically twisted twined yarn (1). In methods and devices known per se used to carry out such methods, the rove threads often break and the automatically twisted yarn (1) lacks resistance. The aim of the invention is to provide a method and device for producing an automatically twisted yarn (1) which is as resistant as possible. The phase difference ( phi is thus produced by using at least one deflection roller (5) to guide at least one of the roves (2) onto a guide roller (6) once it has passed through the false twisting device (4), whereupon the roves (2, 3) are combined on the guide surface (6a) of the guide roller (6).
Abstract:
Es wird ein Nähgarn aus mindestens zwei Vorgarnen, die unter Ausbildung des Nähgarnes miteinander verzwirnt sind, beschrieben, wobei jedes Vorgarn die Konstruktion eines Coregarnes aufweist, das eine mindestens eine Seele ausbildende erste multifile Garnkomponente und eine die Seele umspinnende zweite Fasergarnkomponente umfaßt. Im Querschnitt des Nähgarnes gesehen weist die Fasergarnumspinnung des mindestens einen Vorgarnes weniger als 41 Einzelfasern auf. Bei dem Verfahren zur Herstellung des Nähgarnes werden mindestens zwei Vorgarne zunächst erstellt, wobei zur Erstellung eines jeden Vorgarnes eine aus Fasergarnen erstellte Lunte zusammen mit der als Seele dienenden multifilen Garnkomponente einer Spinneinrichtung zugeführt und dort versponnen wird und hiernach die mindestens beiden Vorgarne miteinander verzwirnt werden. Die Lunte des Fasergarnes wird unmittelbar vor dem Zuführen zur Spinneinrichtung so weit verdichtet, so daß im fertigen Nähgarn die Fasergarnumspinnung von mindestens einem Vorgarn über den Querschnitt des Nähgarnes gesehen weniger als 41 Einzelfasern, vorzugsweise zwischen 20 Einzelfasern und 38 Einzelfasern, aufweist.
Abstract:
The present invention refers to a spinning device, having a drafting device D which drafts a fiber bundle, a spinning member P positioned in the downstream side of the drafting device D and a winding part W which winds a spun yarn Y produced by the spinning member P, wherein the spinning member P is formed by arranging a plurality of the yarn producing units having a hollow guide shaft 28, a yam passage 32 formed in the central part along the axis of the guide shaft 28 and an air jet nozzle 21 which generates a revolving airflow in a spinning room 20 which is in a tip part 29 of the hollow guide shaft 28; a doubled-yarn guide 8 is provided between the spinning member P and the winding part W; the single yarns Ya and Yb produced by the yarn producing units are united in the doubled-yarn guide 9 and wound to a winding package 12 in the winding part W as doubled yam Y and the single yarns Ya, Yb, do not balloon therefore between the spinning member P and the doubled-yarn guide 8, (Fig. 1).
