    摘要： Provided are a double raschel knitted fabric having ridges, wherein shape stability of ridges and recesses, seam strength, and tensile resistance of recesses are excellent, and an surface covering material containing said fabric. The double raschel knitted fabric according to the present invention includes a double-layer knitted fabric having a surface layer and a back layer, and a connecting thread that connects the knitted fabric of the two front and back layers, and a plurality of ridges and recesses located between the ridges are formed in at least one knitted fabric of the two front and back layers, the double raschel knitted fabric characterized in that the ridges are formed by combining two or more wales of stitch rows continuing in the warp direction, and the ridges are connected to adjacent ridges on at least one side by sinker loops.

    摘要： Upholstery tufting apparatus comprises an insertion needle (5) with an aperture (4) to receive a tuft for insertion into an article to be upholstered. The tuft is presented to the needle aperture (4) along a tuft feed axis (3). The apparatus has a plurality of tuft strings (2a, 2b, 2c), a first string (2a) with tufts of a first length and a second string (2b) with tufts of different second length. The apparatus has one or more tuft feed units, and an actuator operatively connected to said tuft feed unit(s). The first and second tuft strings (2a, 2b) are associated with the tuft feed unit(s). A selected one of the tuft feed unit(s) is actuatable by the actuator to align one of the first and second strings (2a, 2b) with the tuft feed axis (3) according to the length of tuft required to be inserted into an article to be upholstered. A method for tufting an upholstered article employing said apparatus is also described.

    摘要： Presented herein are active textile structures with selectively variable surface friction characteristics, methods for making/using such structures, and vehicle components fabricated with electronically controlled textile structures with modifiable surface friction characteristics. An active textile system for governing frictional force levels at an interface with a user or object is presented. The system includes a textile structure that is fabricated from interlaced first and second textile filaments. Each textile filament has a respective texture that exhibits a distinct coefficient of friction. The textile structure has an outer and/or upper contact surface at the interface with the user/object. An actuating element, which is connected to the textile structure, is operable to selectively transition the textile structure between first and second states. The first state includes the first textile filament defining the textile structure's outer contact surface, whereas the second state includes the second textile filament defining the outer contact surface.
