Aiming at the characteristic of good biodegradability of nylon-6 wastewater,the hydrolysis acidification/two-stage bio-contact oxidation process was adopted.

THE DEVELOPMENT OF PA LUSTROUS PROFILED INTERLACED HOY;

The production process of high elastic PA6/PET multi-islands fiber in which PET was for the island and PA6 was for the sea was introduced.

The present situation of production and the development of various carpets, such as PA, PET, PP, PTT, in the world are described, based on the prsent situation of development in Chian car- pet industry, some suggestions are put forward.

Mechanical properties of functional nano-nylon fiber;

The disscussion on two standards testing for drawing capabilities of nylon 6 cord;

The Influence of Nylon POY Storage Time on Fiber Property;

The maintaining requirements of polyamide fiber and poly-phenylene terephthalamide materials in warehouse were analyzed by the trial of relative humidity effecting degradability of them in the paper.

The tensile property of polyamide fibers and polyamide fibers sprayed with metals are tested in the paper.

In this paper, creep property of polyamide fibers and polyamide fibers sprayed with metals is studied by Instron Series 5565 Universal Testing Machine, and their creep prosperities with different stress levels and different tensile speeds with same stress levels are also tested.
