Fiber Materials AC Impedance Spectroscopy and Its Application Xiaofeng Li 1,a ，Xianggao Pan 1,b 1Hunan University of Arts and Science, Changde, Hunan, China 415000 a lxfyb@21cn.com, b pxg987654321@163.com Keywords: AC impedance Spectroscopy, Bathtub effect, fibrous material, moisture regain ratio.
This article presents a recent study on the behavior of impedance versus frequency of fiber materials.
To eliminate the faults of DC impedance technique in measuring fiber moisture regain, this paper proposed a novel technique to test moisture regain of fiber materials by way of testing AC resistance.

Current Status of New Materials With the constant development of the sweater industry, new materials have become the priority and foremost condition for the creation of sweater products.
New raw materials, such as modal, tencel and fancy yarns, have not only given new concept of science, but also upgraded the intrinsic artistic quality of sweaters by virtue of their unique yarn structure and injected full of vigorousness to enterprise, bring about abundant economic profit.
Influence of Raw Materials on Sweater Products From the perspective of sweater products, the raw material plays as an important role influencing the overall style of the sweater.

RE has considerable influence on the comprehensive properties of copper-based electrical contact materials.
Basically there are two types of contact materials.
SPS is referred to an advanced technology that is used to prepare and synthesize materials with different properties, like ceramics, composite materials, etc.
New materials such as nanometer blocks, bulk amorphous blocks, multi-dimensioned materials with composite structure and functional gradient are also processed through SPS [4-7].
