The bamboo-cage loom in Guangxi province in China is a great invention in the textile history of the Chinese minorities. However, the previous studies on the bamboo-cage loom were not very clear, and led to much misunderstanding. Based on our investigation on the spot of some ethnic villages in Guangxi province and in Guangxi Museum of Nationalities, at first, the structure of bamboo-cage loom was introduced in detail. Secondly the characters of Zhuang brocade on the bamboo-cage loom were presented. At last, the operational processes on the bamboo-cage loom were explained.

The results showed that: 11 groups of training samples randomly selected from 13 groups samples, two groups as predict sample, forecast errors are below 5% with high accuracy. This research provides a new approach for the spinning process design and quality control.

In this study, the thermal properties of a kind of new geotextile materials, so called controlled permeable formwork (CPF), were studied. Thermo-gravimetric analysis showed that the weight of CPF didn’t change much between 0~350 °C. Dynamic mechanical analysis showed that the storage modulus of CPF reduced from 25 MPa to around 10 MPa when the temperature rose to above 100 °C. The strength of sample decreased slightly with the increase of the temperature. The breaking elongation changed slightly with a maximum at 80 °C. The CPF showed excellent thermal stability and was suitable for general use in construction work.

In this paper, UV spectrophotometry was used to test the chromium content of bast fiber of ramie and diphenylcarbazide (DPC) was used as color reagent. The optimal technology was: dropping volume of phosphoric acid 0.4～0.6 mL, DPC content 2.0~4.0 mL and coloration time 5-10 minutes. The results showed that complexes were formed from Cr (VI) ions and DPC under phosphoric acid condition. There was a maximum positive absorption peak at the 540nm. Cr (VI) concentration (in the range of 0.004～1.000 mgL-1) and the absorbance (A) of complex obeyed the Lambert-Beer law.

Keratins from wool were reduced by the optimize method(PH 7.0, NaHSO350wt%, Urea 200wt% and SDS 15wt%), wool 5g, distilled water100mL, shaken at 80°C inconstant temperature water-bath for 24h, filtered through different nylon screens with 50-300 aperture using decompression filtering, dialyzed against distilled water afford a colorless and clear solution. The keratins main molecular weight was 35,000-45,000 Daltons; a clear film is readily prepared from a keratin solution containing glycerol or PEG on the basic of SMS nonwovens; the films moisture content was changed while glycerol concentration changed from 5% to 25%; the film was insoluble in water and organic solvents. The films were tested by SEM, Ultraviolet and FTIR.

In response to the problem for non-washable and poor taking comfortable characterizations of smart electronic fabrics at present, two different organizational structures of fabric sensors with plain weave and double weave are designed. The basic principle of design of fabric sensor is: the core-spun yarn made of metal wire is used as core wire, the structural unit with capacitor function is built by interweaving warp with weft, and the induction of fabric to external pressure is reflected by testing changes in capacitance of fabric. The models of equivalent electronic circuits of two fabric sensors with plain weave and double weave are analyzed, and the relationships between area and capacitance characteristics of fabric sensor are discussed. The results show that: the larger the fabric area, the greater the capacitance, and the capacitance of 36cm2fabric is maximum with 100Hz test frequency; under the condition of the same area and test frequency, the capacitance of plain weave fabric is greater than that of double-layer fabric under no pressure, but the increasing rate of capacitance of double-layer fabric is larger than that of plain weave fabric under the same pressure.

The high resolution and wide measurement range are important for the displacement measurement based on the grating moiré fringe at present. 50lines/mm coarse grating scale is chosen often in order to carry out the wide range. Therefore, the realization of the high resolution is a difficult problem for coarse grating scale. The paper proposes a new nanometer subdivision method with CCD based on the disadvantages of previous moiré fringe collection method. CCD replaces the traditional photoelectric triode and converts moiré fringe to the pixels signal output, which can improve the moiré fringe quality of grating scale. The pixel is the basis unit of CCD; the pixel number decides directly the measurement resolution and precision. The paper chooses the liner array CCD TCD1501C that has 5000 pixel units and 7μm pixel unit，which ensures the nanometer resolution. The output signals of CCD are processed by amplifier, filter, 12 bit analog-digital converter and sent to the core processor of FPGA. The FPGA consisted of all digital system including CCD driver, subdivision, identification direction, displacement calculation, display and key control functions. The paper gave the principle of nanometer subdivision, block diagram of FPGA module and simulation waveforms.
