摘要:
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.
摘要:
The present invention relates to a composition and a method for treating substrates, such as fabrics; particularly to make the substrate stain repellent. The invention has been developed primarily for use on fabrics and glass, and will be described hereinafter with reference to these applications. It is an object of the present invention to provide both aqueous and oily stain repellence. We have found that some or all the problems of prior art may be solved or ameliorated with aqueous-alcoholic compositions which include a water-soluble salt of a multivalent metal ion, and a fluoro alkoxy silane with the ratio of water-soluble salt: fluoro alkoxy silane is from1:5 to 5:1.

摘要:
Disclosed are absorbent structures including fibers bound with a polyvalent cation-containing compound and superabsorbent polymer particles. The fibers exhibit an ion extraction factor of at least 5 %. Also disclosed are multi-strata absorbent structures, such as disposable absorbent articles, including the treated fibers and SAP particles. Further disclosed are methods for preparing absorbent structures including the treated fibers; structures including fibers combined with a polyvalent cation-containing compound; and methods for treating or coating SAP particles with polyvalent cation-containing compounds.
摘要:
A process for producing a regenerated fiber by treating a regenerated collagen fiber with a monofunctional epoxy compound and a metallic aluminum salt characterized in that, in the treatment with the monofunctional epoxy compound, sodium hydroxide is added to such a level as giving a concentration of 0.001 to 0.8 N in the liquor to be treated and the treatment is initiated by adding an inorganic salt in such a level as to give the water absorption ratio of the regenerated collagen fiber product of 100% or lower depending on the amount of the sodium hydroxide added; and a process for setting the regenerated collagen fiber characterized by heat-setting the regenerated collagen fiber obtained by the above production process by a wet heat treatment at 50 to 160 DEG C and a dry treatment at 20 to 220 DEG C.
摘要:
A new approach for improving fire resistance of cellulosic materials is provided, especially when the cellulosic material is to be used in polymer composites. Cellulosic material is treated with an aqueous mixture of alkali metal or ammonium hydroxide and alkaline earth or aluminum metal salt simultaneously with or within a short period of time of preparing the mixture. The treated cellulosic material becomes self-extinguishing and may also have improved thermal stability, improved interfacial thermal resistance, improved resistance to damage by oxidants and other chemical agents, improved resistance to biological agents and/or improved resistance to damage by ultra-violet light.
