The present subject matter provides an antimicrobial cleaning cloth, including: nonwoven fabric fibers; and copper fibers. A method for manufacturing the antimicrobial cleaning cloths includes: mixing nonwoven fabric fibers and copper fibers; carding the nonwoven fabric fibers and copper fibers; cross-lapping the nonwoven fabric fibers and copper fibers; needle-punching the nonwoven fabric fibers and copper fibers to form a nonwoven fabric comprising copper fibers; slitting the nonwoven fabric comprising copper fibers to form nonwoven fabric sheets; winding the nonwoven fabric sheets to form nonwoven fabric sheet rolls; and cutting the nonwoven fabric sheet rolls to antimicrobial cleaning cloths. A system for manufacturing the antimicrobial cleaning cloth and additional embodiments of the antimicrobial cleaning cloth, the method of manufacturing the same and the system for manufacturing the same are disclosed herein as well.

Application: when manufacturing porous units with directional through channels. The essence of the invention: the technique of production of an open porosity converter working element implies that fibers of preset linear dimensions and cross-section are manufactured prior to formation of a preform of the working element. Formation of the preform is implemented by way of layering of fibers. Fibers are laid in each layer to form through channels between them. The position of fibers in the shaping fixture is fixed. After that fibers are integrated through heating. During heating the process fixative is removed, stresses are removed and the fiber surface is cleaned. Preforms of the converter working elements are heated in the controlled atmosphere up to the desired temperature and soaked at such temperature under discharge until the fibers are baked to constitute the organic whole. Upon completion of baking converter working elements are cooled and removed out of the form.

The invention relates to a method of assembling a fiber network comprising a plurality of metal fibers, wherein the method comprises the following steps: providing a loose network out of the plurality of metal fibers at an assembling site; fixing the plurality of metal fibers to one another by forming contact points between the single metal fibers by heating the plurality of fibers at a heating rate higher than 50 K/min, in particular higher than 100 K/min, especially higher than 200 K/min, preferably higher than 1000 K/min, to a fixation temperature selected in the range of 50 to 98% of their melting point temperature; and cooling the plurality of fibers at a cooling rate higher than 50 K/min, preferably higher than 100 K/min. The invention further relates to a network of metal fibers comprising a plurality of metal fibers fixed one to another at contact points, wherein the metal fibers non- round cross section, in particular a rectangular, quadratic, partial circular or an elliptical cross section with a large axis and a small axis, or wherein the metal fibers comprise a round cross section, and wherein the fibers comprise a width which is generally constant along a length of the fiber such that a variation of the width of the fiber along its length is less than 40%, preferably less than 30%, in particular less than 20%. 20
摘要:
Bei dem Verfahren zur Herstellung von offenporösen Knochenimplantaten mit frei zugänglichen Leitstrukturen aus Fasern, die aus einem biokompatiblen Metall oder Metalllegierung gebildet sind, werden lange Fasern in mehreren Lagen jeweils in Form eines Vlieses, bei dem die Fasern in jeder Lage in einer gemeinsamen bevorzugten Achsrichtung ausgerichtet sind, übereinander angeordnet. In mindestens einer der Lagen wird eine Vernadelung, bei der einzelne Fasern der jeweiligen Lage in eine Achsrichtung ausgerichtet werden, die sich um mindestens 60° von der bevorzugten Achsrichtung, in der die anderen Fasern der Lage ausgerichtet sind, unterscheidet, durchgeführt. Die übereinander angeordneten Lagen werden in einer Heizeinrichtung punktuell über Sinterbrücken an Fasern stoffschlüssig durch eine Sinterung miteinander verbunden.
