A compound equipment of a latex-free tufted carpet is provided. The compound equipment includes an unwinding device, a compound roller, and a shaping device. The unwinding device is configured to unwind a rolled blank blanket, a hot-melt fiber mesh, and secondary cloth. The compound roller is configured to stack and compound the unwound blank carpet, the unwound hot-melt fiber mesh and the unwound secondary cloth in sequence to obtain a preformed tufted carpet. The shaping device is configured for the setting of the preformed tufted carpet at a preset temperature to obtain a finished tufted carpet. Combined with the hot-melt fiber mesh, the secondary cloth and the blank carpet are consolidated by means of thermally induced bonding, and latex is not needed for consolidation.

NANOFIBER WRAP YARN AND PREPARATION METHOD THEREFOR, AND NANOFIBER WRAP YARN STRAND AND APPLICATION THEREOF
A nanofiber wrap yarn and a preparation method therefor, and a nanofiber wrap yarn strand and an application thereof, relating to the technical field of antibacterial textiles. The nanofiber wrap yarn comprises a core yarn and an outer wrapping layer wrapping the surface of the core yarn; the core yarn is a polypyrrole-cotton yarn; the polypyrrole-cotton yarn comprises a cotton yarn and polypyrrole particles distributed on the surface of the cotton yarn; the outer wrapping layer is made of an antibacterial nanofiber; and the antibacterial nanofiber comprises a polyacrylonitrile nanofiber matrix and ketoconazole and nano zinc oxide which are distributed on the polyacrylonitrile nanofiber matrix. The nanofiber wrap yarn has a relatively good inhibition effect on fungi and bacteria, particularly has a certain treatment effect on tinea pedis, is relatively low in cost, safe and reliable, and has durability and sustained release performance.
A self-attention-based method for detecting a defective area of a color-textured fabric. The method specifically comprises: establishing a color-textured fabric data set which comprises a color texture defect-free image, and superimposing noise on the color texture defect-free image in the color-textured fabric data set; constructing a Transformer-based Swin-Unet model and training same to obtain a trained model; and reconstructing, by using the trained model, a color-textured fabric image to be subjected to detection, outputting a corresponding reconstructed image, and then determining and positioning a defective area according to the reconstructed image. By means of the method, the problem of the detection of a defective area of a color-textured fabric can be effectively solved.
Disclosed in the present invention is an autoencoder-based detection method for a defective area of a colored textured fabric, specifically comprising: superimposing noise on a defect-free image of a colored textured fabric in a colored textured fabric data set; constructing a second memory-guided quantized variational autoencoder model; training the second memory-guided quantized variational autoencoder model according to a training parameter by using the noise-superimposed defect-free image of the colored textured fabric; and reconstructing, by using the trained second quantized variational autoencoder model, all images to be detected of the colored textured fabric, outputting respective corresponding reconstructed images, and then detecting to position a defective area. According to the present invention, a defect of the fabric can be quickly detected and positioned by calculating a residual of the images to be detected of the colored textured fabric and the corresponding reconstructed images and combining adaptive thresholding and closing operation processing, such that the situation of missed detection or over detection of a defective area is reduced.
A preparation method for a piezoelectric yarn reinforced resin-based composite material, comprising: preparing a piezoelectric core-spun yarn of which the core layer is carbon fiber and the skin layer is a piezoelectric polymer fiber net by utilizing an electrostatic spinning parallel electrode method; acquiring a piezoelectric yarn of which the outer layer is carbon fiber, the middle layer is a piezoelectric polymer fiber net and the core layer is carbon fiber by utilizing two-dimensional weaving; coating the piezoelectric yarn with a PU film to obtain PU-coated piezoelectric yarn; acquiring a woven fabric with carbon fibers as warp yarns and piezoelectric yarns wrapped by the carbon fibers and PU as weft yarns by utilizing three-way orthogonal weaving; and acquiring the piezoelectric yarn reinforced resin-based composite material by means of vacuum-assisted resin transfer molding technology. The piezoelectric yarn is implanted into the composite material, and the mechanical properties of the composite material are monitored by means of the piezoelectric change of the piezoelectric yarn in the composite material along with the increase of strain for the health monitoring of damage.
