摘要:
The present invention relates to artificial grass composed of fibres comprising a core and a cladding, which core and which cladding are made of different materials, wherein the material for the cladding has a hydrophilicity which is different from the hydrophilicity of the material used for the core.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung cellulosischer Mehrkomponentenfasern mit vermindertem Quellvermögen und erhöhter Nassscheuerbeständigkeit. Diese Aufgabe wird dadurch gelöst, indem man 75 bis 25 Volumen % Cellulose mit 25 bis 75 Volumen % mindestens einer weiteren faserbildenden Polymerkomponente in einer wasserhaltigen ionischen Flüssigkeit unter Zusatz von Stabilisatoren dispergiert, unter Scherung, Temperatur und Vakuum das Wasser weitestgehend entfernt, die entstehende mikroskopisch homogene Lösung durch mindestens eine Spinndüse zur Faser/Faserschar verformt, unter Verzug durch einen klimatisierten Spalt führt, die orientierten Lösungsstrahlen durch Behandeln mit einer temperierten Lösung, die mit der ionischen Flüssigkeit mischbar für die Cellulose und die weitere faserbildende Polymerkomponente aber ein Fällungsmittel darstellt, unter spinodaler Entmischung ausfällt, vom Fällbad trennt und anschließend nachbehandelt.
摘要:
A method for forming a polycomponent fibre comprising a first, fibre-forming component comprising a polymer, and a second, component comprising an active ingredient that will selectively reduce or remove components of tobacco smoke, the method comprising the steps of: i. forming a dispersion, second solution or liquid comprising the second component; and ii. coextruding the first component and the dispersion, second solution or liquid through a jet or aperture to form a fibre comprising a first portion formed from the first component, and a second portion formed from the second component.
摘要:
Cellulosic fibers having enhanced reversible thermal properties and methods of forming such cellulosic fibers are described. In one embodiment, a cellulosic fiber includes a fiber body formed of an elongated member. The elongated member includes a cellulosic material and a temperature regulating material dispersed within the cellulosic material. The temperature regulating material includes a phase change material having a transition temperature in the range of -5°C to 125°C. The cellulosic fiber can be formed via a solution spinning process and can be used in various products where thermal regulating properties are desired. For example, the cellulosic fiber can be used in textiles, apparel, footwear, medical products, containers and packagings, buildings, appliances, and other products.
摘要:
The present invention provides a coloured fibre comprising one or more composite filaments of cellulose and cellulose acetate, wherein the colour is effected by a disperse dye.
摘要:
A fine fiber can be made having a structure with an axial core and a coating layer. The fiber can have a polymer core and one or two layers surrounding the core. The fine fiber can be made from a polymer material and a resinous aldehyde (e.g., melamine-aldehyde) composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.
