摘要:
An antistatic fiber obtained by melt spinning of a fiber-forming thermoplastic polymer containing at least one of polyoxyalkylene glycol and its derivatives in an amount of not less than 0.5% by weight, characterized in that said fiber has a half life time of electric charge leakage of not more than 150 seconds before and aftertreatment with a weight decreasing agent and, when treated with a weight decreasing agent, provides a number of streaks arranged in parallel in the lengthwise direction at the surface.
摘要:
Wettabie fibers and/or filaments are prepared from ole-Wettable fibers and/or fitaments are prepared from fin polymers, especially linear low density copolymer (LLDPE), by incorporating into said olefin polymer at least one wetting agent of the group comprising (a) an alkyoxylated alkyl phenol along with a mixed mono-, di-, and/or tri- glyceride, (b) a polyoxalkylene fatty acid ester, or (c) a combination of (b) and any or all parts of (a).

Artikel aus Baumwolle und Acrylfasern, die einer Blech behandlung mit Wasserstoffperoxid unterworfen werden, zeigen dann keine Vergilbung der Acrylfasern, wenn diese 0,05 bis 5 Gew.-% einer mehrfunktionellen Phosphonsäure, Phosphoncarbonsäure oder eines Phosphonsäuregruppen enthaltenden Polymerisates enthalten.
摘要:
Fabrics of reduced static propensity are obtained from cospun yarns comprising a major amount, up to 70 weight percent, of poly(ethylene terephthalate) filaments with the remainder being poly(hexamethylene terephthalamide) filaments containing 3 to 10 weight percent of an N-alkyl substituted polycarbonamide, the filaments having a denier of from 1 to 10.
摘要:
A conductive polymer comprising a fibre-forming synthetic polymer having dispersed therein as a separate phase between 1 % and 20% by weight inclusive based on the polymer of a polyalkoxylated phenol-formaldehyde condensate. Conductive fibres may be produced by melt spinning the conductive polymer.
摘要:
In thermal stabilization of poly(a-olefin) fibers, such as a melt spun polypropylene, in which the poly(a-olefin) contains a hindered phenol, an organic phosphite, a hindered amine, and a metal salt of a fatty acid, the further inclusion of an alkali metal phosphate, such as sodium phosphate, results in improved thermal stability of the finished fiber.
摘要:
The present invention discloses a flame-retardent acrylic synthetic fiber comprising acrylonitrile and a vinyl monomer copolymerizable therewith and containing a finely divided inorganic tin compound. The fiber has high flame retardancy, outstanding gloss and transparency, and satisfactory whiteness and dyeability.
摘要:
This invention provides a radio opaque fibre comprising polypropylene, a coupling agent and 55% to 70% of barium sulphate. The coupling agent is preferably isopropyl triisostearoyl titanate. The fibre finds particular application in manufacture of surgical swabs and dressings.
摘要:
A hollow polyester fiber of an excellent antistatic property composed of a single polymeric component and having a hollow extending along the longitudinal axis thereof and in which the hollow ratio is at most 15%, which fiber contains (a) a polyoxyalkylene glycol substantially non-reactive with said polyester and (b) an ionic antistatic agent, dispersed through the fiber in an amount of at most 3% by weight based on the weight of the fiber, and wherein the polyoxyalkylene glycol (a) is predominantly dispersed in a core portion of the fiber in a high density. The fiber is also excellent in tensile strength, resistance to fibrillation and dyeing property.
摘要:
@ Disclosed is a fiber for a heat insulating material which contains 1-30 wt.% of a metal or metal oxide powder and has an emissive power of not more than 0.3 and an average particle size of 1-100 µm. The fiber preferably has a flatness of at least 2 in the cross-section or is a sheath-core type composite fiber, the sheath component containing a larger amount of the metal or metal oxide powder than the core component. The fiber may be used as a non-woven fabric or a wadding structure. It also may be used in the form of a net-like fiber sheet.
