The invention discloses a method and a device for improving the wear resistance of yarn wet joints. The method for improving the wear resistance of wet joints of yarns comprises the following steps: the spray liquid storage device sprays the spray liquid to the yarn joints, and the spray liquid contains colloidal particles, powder particles and emulsifiers. The two heat treatment splints of the heat treatment component move to the yarn joint, and clamp the yarn joint between the two heat treatment splints, and the heat treatment splints are heated to a predetermined temperature for a predetermined time, and the two heat treatment splints The heat treatment splint reset. The device for improving the wear resistance of yarn wet joints according to the invention makes the yarn joints have strong wear resistance and the yarn joints are not easily broken.

The invention relates to a carbon fiber cloth loom, comprising a frame, a shedding mechanism, a let-off mechanism, a weft insertion mechanism, a weft-yarn shut-off mechanism, and a take-up mechanism. The carbon fiber cloth loom is characterized in that the loom also comprises an automatic weft releasing and feeding mechanism composed of a sliding plate, a driving structure, a bracket, a set of guide rolls and an air claw; the weft insertion mechanism is composed of a first servo motor, a gear reducer, an arrow wheel and a rigid arrow shaft; the let-off mechanism is composed of a second servo motor, a let-off shaft, a guide shaft and a detection tension shaft; and the take-up mechanism is composed of a rewind shaft and a third servo motor. Each motion part of the loom provided by the invention is driven by an independent power source, and is controlled by a PLC (programmable logic controller) in a centralized way, so that the structure is simplified, and the operating control is convenient; the automatic weft releasing and feeding mechanism ensures that a weft yarn plate is in a specific spatial position before weft insertion, and guarantees the success of each weft insertion; the weft insertion mechanism ensures the weft yarn plate not to wear a warp yarn plate when the weft yarn plate passes through from a shed; and the weft yarn plate introduced to the shed is pushed to a cloth fell by the backward motions of the second servo motor and the third servo motor, so that the requirement for weaving large-width carbon fiber sheet is met.

The preparation method of a long-acting deodorizing and deodorizing core quilt fabric disclosed by the present invention comprises the following steps: (1) The preparation step of physical adsorption deodorizing yarn, the physical adsorption deodorizing yarn adopts 30% bamboo charcoal polyester fiber and 70% % cotton blended; (2) Weaving step; (3) Antibacterial and deodorizing finishing step, this step is to dry the fabric obtained in step (2) at a temperature of 100-120°C after padding and compounding the solution. The drying time is 40-60s, and the compound solution is made of DC-5700, Hert antibacterial deodorant and water, and the mass ratio between the three is 1-3:5-8:89-94. The core quilt fabric of the present invention has physical adsorption and similar biocatalytic deodorization function, can absorb odor through the micropores of bamboo charcoal fiber, and can make three Oxidation caused by conversion of valent iron to ferrous iron achieves permanent odor removal.

The invention discloses a novel cloth guide roller, which comprises a bracket, a pressure spring, a swinging bracket and a cloth guide roller, wherein the swinging bracket is connected on the bracket through a pin shaft; the pressure spring is fixed on the bracket opposite to the pin shaft; an adjusting screw is arranged on the circumference surface of the pressure spring; and the cloth guide roller is fixed on the bracket by a bearing. According to the novel cloth guide roller disclosed by the invention, the spring is arranged to pressurize the cloth guide roller, so that the cloth guide roller is tightly close to the surface of a licker-in roller, cloth cannot be eased away, and the shutdown operation during doffing can be omitted, and thus the loom efficiency is increased and the starting marks caused by doffing shutdown are reduced. A rough rubber surface is wrapped outside the cloth guide roller so as to prevent burrs of the licker-in roller from damaging, and the cloth can be seized by the rough rubber surface and the burrs of the licker-in roller so as to avoid the cloth creasing phenomenon.

The invention discloses a device and method for improving abrasion resistance of a yarn connector. The device for improving abrasion resistance of the yarn connector comprises a liquid storage tank, a movable faller, a heating component, a yarn clamping arm, a detecting component, a first drive component driving the movable faller to move, a second drive component driving the heating plate to move and a third drive component driving the yarn clamping arm to move. The liquid storage tank is provided with a plurality of liquid outlets which are distributed in line. Intervals are formed between the adjacent liquid outlets. The movable faller is located in the liquid storage tank and provided with a plurality of needle teeth. The needle teeth are sequentially arranged, intervals are formed between the adjacent needle teeth, and the movable faller is in a comb shape. The size of the sections of the needle teeth is smaller than that of the liquid outlets. The needle teeth of the movable faller are embedded in the liquid outlets in a matched manner. According to the device and method for improving abrasion resistance of the yarn connector, disengaging is not likely to happen at the yarn connector, and the bonding effect is good.
