Flexible fabric keyboard is a field of smart textile. It can overcome traditional horniness keyboard can’t be foldable and washing. In this laboratory study there is Three Layers Weaved Once structure designed which consists of three kinds of orifice dimension, for example 4 wefts, 8 wefts and 12 wefts. At the same time three kinds of conductive filaments number combined are planed for each orifice dimension. There are 1, 4 and 8 roots of filaments combined together so that contact areas of the conductive material are changed. Then the immediate regain, connection pressure and connection ratio are tested and analyzed for every kind of fabric keyboard switch. It is concluded that 4 wefts orifice dimension and 4 roots of filaments combined is a better project. These findings may assist in recommendations regarding the further development of flexible fabric keyboard. The fabric keyboard switch forms the foundation for many smart textile applications.

Fabric keyboard is a field of smart textile. It can overcome many disadvantages of conventional keyboard. In order to study the fabric keyboard switch, trapezia structures of two kinds of orifice dimension are designed for example 8 wefts and 16 wefts. Different roots of conductive wires are woven into the down layer of the orifice part for each kind of orifice dimension. 4 and 8 roots of wires are woven for 8 wefts. 4, 8 and 16 roots of wires are woven for 16wefts. Then the immediate regain, connection pressure, connection ratio and contact resistance are tested and analyzed for every kind of fabric keyboard switch. It is concluded that 8 wefts orifice dimension and 8 roots of wires woven into the down layer of the orifice part is a better project. These findings may assist in recommendations regarding the further development of flexible fabric keyboard.

Flexible fabric keyboard is a field of smart textile. It can overcome traditional horniness keyboard can’t be foldable and washing. Because conventional keyboard’s switch is matrix circuit, two conductive layers are not touchable due to action of a middle insulating layer in relaxing. When the key is pressed, two conductive layers contact and form electric current. In this laboratory study there are two kinds of methods adopted, for example, Three-layer Fabric Weaved Separately (TFWS) and Three-layer Fabric Shaped Once(TFSO). They were significantly different in weaving methods, fabric structure and weaving efficiency. Three species were designed for every method. Although Connection Ratio (CR) of 6×6 and 8×8 in TFWS was 100%, TFWS took many repeating and complex processes. Much time and labor were seriously spent so that weaving efficiency was consumedly reduced. However, if making use of Three-layer Fabric Shaped Once(TFSO) which adopted three dimensional weaving method, only one procedure was required for fabric keyboard matrix circuit. The three dimensional weaving fabric consisted of support part and orifice part. When pressed in the key position, the top and down layer of the orifice part can contact with each other. Then the circuit can connect. When the applied force was released, the top and down layer can return to primary position due to the action of the support part. TFSO didn’t require many repetitive and complex courses. Therefore the weaving efficiency can be greatly increased. To be more importantly, CR of 16 wefts in TFSO was comparatively not bad among in three species of TFSO. When considering all six species for two methods together, 16 wefts in TFSO appears to provide the most suitable fabric for flexible fabric keyboard matrix circuit as a result of shaping once, high weaving efficiency and 100% CR. These findings may assist in recommendations regarding the further development of flexible fabric keyboard.

Flexible fabric keyboard is a field of smart textile. It can overcome traditional horniness keyboard can’t be foldable and washing. Because conventional keyboard’s switch is matrix circuit, two conductive layers are not touchable due to action of a middle insulating layer in relaxing. When the key is pressed, two conductive layers contact and form electric current. In this laboratory study there are three kinds of structure designed such as through-thickness angle interlock, trapezia and X shape structure which consist of the support part and the orifice part. Conductive filaments are 8 roots for the warp and weft conductive material. Then the weaving time, elastic modulus and connection pressure are tested and analyzed for every kind of fabric keyboard switch. It is concluded that the weaving time of through-thickness angle interlock is the shortest and the elastic modulus of X shape structure is the best, but connection pressure of three kinds of structures is all big. These findings may assist in recommendations regarding the further development of flexible fabric keyboard.

The inheritance and innovation of ancient architecture decoration art is an important way for the development of the construction industry. The data process of traditional ancient architecture decoration art is relatively backward, which leads to the obvious distortion of the digitalization of ancient architecture decoration art. In order to improve the digital effect of ancient architecture decoration art, based on neural network, this paper combines the image features to construct a neural network-based ancient architecture decoration art data system model, and graphically expresses the static construction mode and dynamic construction process of the architecture group. Based on this, three-dimensional model reconstruction and scene simulation experiments of architecture groups are realized. In order to verify the performance effect of the system proposed in this paper, it is verified through simulation and performance testing, and data visualization is performed through statistical methods. The result of the study shows that the digitalization effect of the ancient architecture decoration art proposed in this paper is good.
