This invention discloses a tool and method for constructing a horizontal wellbore through repeated volumetric fracturing. The tool includes a surface control device and a downhole main unit, with the surface control device located outside the downhole main unit. The downhole main unit includes a cylinder, with a top seat and a base connected to its top and bottom ends via upper and lower bearings, respectively. Both the top seat and the base are cylindrical. An electric motor is installed inside the base and connected to the surface control device and the lower bearing. A magnetic positioning device is installed inside the cylinder and connected to the surface control device. Several nozzles are provided on the sidewall of the cylinder, and each nozzle has a pressure-bearing, fracture-resistant outer wall matching its size. A connector for connecting to tubing is fixedly installed at the upper end of the top seat. Packers are installed on the outer sides of both the top seat and the base. This invention can reduce the amount of materials used in wellbore reconstruction and lower construction material costs.

The application relates to the technical field of automobile parts, and particularly discloses a PET flocking recyclable yarn and an automobile carpet, wherein the PET flocking recyclable yarn is composed of modified polyester fibers and wool fibers; the modified polyester fibers comprise the following raw materials: PET chips, a flame retardant, hemp stem core superfine powder, nano silicon dioxide and a lubricant; the formula of the above scheme is simple, the obtained PET flocking recyclable yarn has excellent flame retardance, remarkable wear resistance and good mechanical properties, and can be recycled and reused; the automobile carpet comprises a carpet surface layer, an anti-skid layer and an antibacterial layer in sequence, and the layers are bonded through an adhesive; the carpet surface layer is spun from the PET flocking recyclable yarn; the anti-skid layer is formed by a layer structure of foaming material; the obtained automobile carpet has excellent comprehensive performance and wide market prospects.

The invention belongs to the technical field of articles of daily use, and discloses an ice silk cool-feeling antibacterial anti-mite pillow and a preparation process thereof. The pillow inner is made of viscose staple fibers, sodium alginate and calcium ions are subjected to ionic crosslinking to form a gel network, xylitol and chitosan quaternary ammonium salt are embedded, a porous structure is constructed through freeze drying, and long-acting slow release of functional components is achieved; according to the pillowcase, a covalent cross-linked network is formed on the surfaces of the ice silk fibers through citric acid-sodium citrate catalytic esterification reaction, and mica powder and polyhexamethylene biguanide hydrochloride are fixed. The preparation method comprises the following steps: mixing, crosslinking and freeze-drying and shaping the pillow core; the pillowcase is subjected to two-time dipping and two-time rolling, segmented baking and finishing, and finally the two are packaged. Through dual chemical cross-linking synergy of the pillow inner and the pillowcase, the problems that functional components are easy to migrate and are not washable are solved, and the pillow has lasting cool feeling, antibacterial and anti-mite performance and washable and durable performance.
