AbstractThis paper reports a preliminary spectroscopic characterization of the surface elemental and phase compositions of Ti49Ni51 alloy treated using various sterilization procedures (autoclaving in water, steam, sealed envelopes; boiling in water and chemical etching). The surface of TiNi is found to consist of a thin oxide covered by a carbon-dominated contamination layer. The surface oxide of autoclaved samples is (TiO2)xNiy where y varies in the range 0-6 at.% depending on the surface preparation procedure. Minor amounts of suboxides as well as metallic Ni are also detected. Preliminary estimations of the oxide film thickness showed that it varies in the range 7- 26 nm depending on the employed method of sterilization. Mechanisms of surface state formation are briefly discussed.

Electroless Ni

Ni-P composite coatings were prepared on cellulose fiber surface via a simple electroless Ni-P approach. The metal-coated extent, dispersion extent of micro or nano cellulose fibers and crystalline structure of Ni-P composite coatings were investigated. The homogeneous hollow composite coatings and metal-coated extent of micro or nano cellulose fibers were improved with the increase in ultrasonic power, and the ideal composite coatings were obtained as ultrasonic up to 960 W. The metallization for cellulose fibers enhanced the dispersion extent of micro or nano cellulose fibers. A uniform coating, consisting of the hollow coating on cellulose fibers surface, could be obtained. At the same time, metallization did not damage the original structure and surface functional groups of cellulose fibers. The concentration of cellulose fibers and ultrasonic power had a direct influence on the metal-coated extent of cellulose fiber surface. The metal-coated extent, dispersion extent of micro or nano cellulose fibers and crystalline structure of Ni-P composite coatings exhibited excellent properties as the concentration of cellulose fibers and ultrasonic power were 2 g/L and 960 W, respectively.

Warmth Retention

A new flame-retardant protein viscose fiber with safely wearing performance has been prepared through blending protein solution, flame retardant (hexaphenoxycyclotriphosphazene) and viscose spinning solution, in which wool protein was used and added to spinning solution on the basis of 16% flame retardant, and the properties of the fiber were investigated. The product has more compact structure inside the fiber and evenly scattered small pores on the surface. Flame-retardant protein viscose fiber can reach the flame-retardant standard both before and after 30 times wash test, and the mechanical strength of the fiber was also improved. The introduction of hexaphenoxycyclotriphosphazene lowered the primary decomposition temperature of viscose fiber, reduced its weight loss. The flame-retardancy of the fiber can be improved by the introduction of protein. In thermal processes, the major product of thermal decomposition was CO2, no hazardous and noxious gases were released. Due to the introduction of protein, moisture regain of the fiber is a little lower than that of viscose fiber, but higher than flame-retardant viscose fiber. Warmth retention property was also improved. Friction coefficient of the product is lower than that of flame-retardant viscose fiber. Bulking intensity was increased, which is better than that of viscose fiber.
