This paper present a design method of double-face jacquard fabric with different patterns based on weft-backed structure. This approach is derived from the design principle of digital double-face jacquard. By overlapping the face and back patterns to produce a piece of transparent pattern, multilayer wefts interweave with monolayer warps in order to created the fabric with different pattern effect on both sides. Superposition of the face and back patterns can integrate processes of two independent designs for the double face jacquard. It doesn’t have any stitching weave structure, which can reduce the difficulty of textile weave design. This strategy reflects the basic design principle of synchronous design for both sides. It has improved the design of traditional weft-backed jacquard and broken through the confine of the figured double-face jacquard fabric which based on the double layer fabric structures.

In order to save water in textile dyeing, the non-ionic reverse micelles were prepared with a non-ionic surfactant Triton X-100 and isooctane by injecting small amount of Acid Black 234 aqueous solution. And then the adsorption and dyeing properties of the dye onto wool in the non-ionic reverse micelle and bulk water were studied, respectively, based on the adsorption mechanism between them examined. The results indicated that Acid Black 234 prefer to exhibit the monomolecular state in the reverse micelle. Low pH values would increase the adsorption amount of the dye onto wool. The adsorption of the dye onto wool showed better agreement with Langmuir isotherm equation and Lagergren second order equation. Acid Black 234 had lower the adsorption amount and diffusion active energy in the reverse micelle than bulk water, but its diffusion coefficient exhibited reverse trend. Little difference in the color characteristics of the dyed wool with Acid Black 234 between in the reverse micelle and bulk water was found. However, a slight decrease in color strength of the dyed wool in the reverse micelle was observed, which may be mainly due to the high diffusion coefficient.

In order to address the problem of low electric efficiency of clutch asynchronous motors used abundantly in the industrial sewing machine control systems, an energy saving motor control system based on the DSP was designed. The industrial sewing machine control system is hysteretic, time-variant and nonlinear, hence the traditional PID control algorithm will reduce the serviceability and reliability of the system because the PID parameters cannot be adjusted timely when the controlled objects are varying. Considering this phenomenon, a late model named BP Neural Algorithm is added to the traditional PID control algorithm, whose self-learning and self-adjusting capabilities help realize the thoughts that parameters of a PID controller can regulate themselves as the system is fluctuating. Furthermore, applying the BP PID algorithm, MATLAB emulations of the energy saving motor control system are conducted, and the results of the emulations demonstrate that the control performance of BP PID is more superb than that of traditional PID. Lastly, the BP algorithm is synthesised in the software design, and achieves a satisfactory consequence.
