摘要:
A treatment agent for fiber products, represented by general formula (I), comprising a combination of a modifier comprising a fluorinated phosphate derivative having a molecular weight of 2,000 or less or a salt thereof with a fixing agent comprising a metal salt compound, wherein R?1 and R2¿ may be the same or different from each other and each represents hydrogen or R¿f?-(CH2)m-, provided that not both of R?1 and R2¿ are hydrogen at the same time; A represents oxygen, sulfur or a direct bond; and n is 1 or 2. A method of treating fiber products with the treatment agent and, if necessary, a fluorinated water and oil repellent or a fluorinated antisoiling finish. Fiber products can retain inherent touch, hand, hue and flexibility even after the treating and use thereof, including washing and friction, and can be endowed with hot water repellency and persistent water and oil repellency.

Die Erfindung betrifft ein Verfahren zur Herstellung von Polymermassen aus Polyolefinen und Stärke und/oder Lignin sowie gegebenenfalls Zellulosefasern durch Polymerisation mindestens eines Olefins in Gegenwart eines Ziegler-Natta-Katalysators. Der verwendete Ziegler-Natta-Katalysator wird erhalten durch Behandeln von weitgehend getrockneter Stärke und/oder Lignin oder eines Gemisches gegebenenfalls mit bis zu 99 Gew.-% an Zellulosefaseranteil mit zunächst einem Aluminiumtrialkyl und danach mit einer Übergangsmetallverbindung der allgemeinen Formel in der
M für Ti, Zr, Cr oder V und R für einen niederen Kohlenwasserstoffrest oder Acetylacetonat steht und n und m gleich oder verschieden sind und jeweils eine ganze Zahl von 0 bis 4 bedeuten, wobei die Gesamtsumme von n + m so gewählt wird, daß M abgesättigt ist.
摘要:
The present invention relates to a process for the metal coating of nano-fibres by electrospinning, to the metal coated nano-fibres obtained by this process and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.

The present invention relates to a water-resistant regenerated collagen fiber containing 12 wt% or more of zirconium salt in terms of zirconium oxide and 2 wt% or more of phosphorus compound in terms of phosphorus. The present invention also relates to a method for producing a water-resistant regenerated collagen fiber, and the method includes treating a regenerated collagen fiber with a zirconium salt to incorporate the zirconium salt into the regenerated collagen fiber, and then treating the regenerated collagen fiber with a phosphorus compound to incorporate the phosphorus compound into the regenerated collagen fiber, thereby obtaining a water-resistant regenerated collagen fiber containing 12 wt% or more of zirconium salt in terms of zirconium oxide and 2 wt% or more of phosphorus compound in terms of phosphorus. The present invention also relates to a fiber bundle for hair including 30 to 100 wt% of the water-resistant regenerated collagen fiber and 0 to 70 wt% of polyester-based fiber.
