A copolymer of propylene with hexene-1 containing from 5 to 9% by weight of recurring units derived from hexene-1, having a melting temperature from 125 to 140 C. and Melt Flow Rate (ASTM D1238, 230/2.16 Kg) from 0.1 to 3 g/10 min., is used to produce blown films having valuable mechanical and optical properties.

In one example embodiment, a film includes a coextruded structure having both an extruded ribbed skin layer that includes a plurality of ribs, and a core layer. The ribs are spaced apart by a web that is integral with the ribs. The film also includes a coloring agent that is substantially more apparent in the ribs than in the web, such that a contrast in color and/or color intensity between the ribs and the web is visible.

A method for installing filler tube includes the steps of: preparing a fuel tank including an opening; preparing an intervening member including a cylindrical member body and an annular member flange; preparing a filler tube including a cylindrical tube body and an annular tube flange; arranging the intervening member so that not only the member body is arranged in the interior of the fuel tank through the opening but also the member flange locks to a front-side peripheral face of the opening of the fuel tank; and welding not only the front-side peripheral with the tube flange but also the member flange with the tube flange by arranging a hot plate in a facing space between the front-side peripheral face and the tube flange and then warming the front-side peripheral face, the member flange and the tube flange.

The continuity of a functional layer of a web (32, 60, 78) is assessed by forwarding the web, detecting (42, 63) the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component (360) in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component (360) in the functional layer. The detectable component (360) can be active or passive. Also included are systems for carrying out the process.

This invention relates to a lyocell material for a cigarette filter and a method of manufacturing the same, wherein the lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to thus obtain a crimped tow.

The invention relates to a method for coating a textile hose (4) with a thermoplastic sealing material (5), in particular polyurethane-based, in a coating device (2). The textile hose (4) has a longitudinal direction and a circumferential direction and is manufactured continuously in the longitudinal direction and in the circumferential direction, in particular formed from a tubular knit hose; the textile hose (4) is fed to the coating device (2) and is continuously drawn onto a mandrel (6) extending in the longitudinal direction and approximately in the vertical direction (8) and is continuously transported further over this mandrel (6), the mandrel (6) being supported and oriented according to the position by at least one support means (10) provided outside the textile hose (4). The thermoplastic sealing material (5) is provided in a heated flowable state and is fed continuously to an entire outer circumference (38) of the textile hose (4) which is continuously transported over the mandrel (6) in such a way that some of the thermoplastic sealing material (5) can penetrate into the textile hose (4) and/or can adhere to the outer circumference (38) of the textile hose (4) and forms a closed superficial coating, and the textile hose (4) coated in this way is then continuously drawn off from the mandrel (6).

In a method for producing a coiled tubing (RW) from a thermoplastic material, in a first shaping step a tubular extrudate (EX) is extruded via an annular nozzle gap (16) in an extruder (12) before, in a second shaping step directly following the first shaping step, the extrudate which is drawn down from the nozzle gap and is still plastically deformable is calibrated in a shaping device (18) in order to obtain a geometrically defined profile cross section (PQ) and is shaped into the coiled tubing, whereupon the coiled tubing having the geometrically determined profile cross section solidifies. This method allows for continuous production of the coiled tubing with a new, high quality in respect of dimensional and shape tolerances on the profile cross section of the coiled tubing. The invention also relates to a device (10) for producing such a coiled tubing.

The invention describes a process for starting up a film production in a film manufacturing machine, in particular a blown film machine, by means of a control device, comprising the following steps: detecting a start-up request setting start-up parameters providing film material commencing the film production setting film production parameters.

A multilayer foam film suitable for direct and non-direct food contact and aseptic packaging application is disclosed.

The embodiments provide a process for preparing a polishing sheet, a polishing pad using the same, and a process for preparing a semiconductor device using the same. The process for preparing a polishing sheet comprises forming a pattern on the surface of a polymer sheet and winding the patterned polymer sheet to form a wound roll in a cylindrical shape. Thus, there are great advantages in that it is possible to control the size and distribution ratio of a fine and uniform pattern at a desired location in an economical and efficient way and to freely design the type, size, structure, physical properties, and the like of the polishing sheet according to the purpose, whereby the application field can be expanded, and a bulk structure can be manufactured.
