A sizing machine with uniform sizing and its application method

Abstract

The invention discloses a slasher capable of sizing uniformly and an application method thereof. The slasher comprises a housing, a sizing tank, a drying room and a DC (Direct Current) power supply; a front guide roller is arranged at the front end of the top of the housing; the front guide roller is of a conductor and is connected with the cathode of the DC power supply; the sizing tank is fixedly arranged in the housing; a front compression roller is arranged at the position close to the front guide roller above the sizing tank; a back compression roller is arranged at the position far away from the front guide roller above the sizing tank; shower nozzles are arranged uniformly at intervals above a position between the front compression roller and the back compression roller; a metal net is arranged in each shower nozzle, and is connected with the anode of the DC power supply; a catch box is arranged below a position between the front compression roller and the back compression roller; the drying room is installed at the position close to the sizing tank in the housing; due to the fact that the sizing sprayed by the shower nozzles is provided with positive electricity, yarn passes through the front guide roller and is provided with negative electricity, so that the sizing can uniformly cover the yarn, meanwhile the catch box can inhale the redundant sizing on the yarn, so that the condensation points of the sizing on the yarn due to the excessive sizing do not occur, and the uniformity of sizing is guaranteed.

Description

Technical field [0001] The invention relates to a sizing machine with uniform sizing and an application method thereof, and belongs to the technical field of textile equipment. Background technique [0002] The sizing machine is a mechanical device commonly used in the textile industry. Its purpose is to coat the surface of the yarn with a uniform sizing film to increase yarn strength and wear resistance, reduce end breakage, and make subsequent weaving smoothly get on. Sizing is the central link of weaving engineering. The performance of sizing machine directly affects the variety development and efficiency of shuttleless looms. For a long time, the sizing process has widespread problems such as complex technology, strong correlation of process parameters, and difficulty in control. Therefore, a good sizing machine plays an extremely critical role in improving weaving efficiency and improving product quality. [0003] The varieties of sizing machines are divided into sizing meth...

Problems solved by technology

However, in order to ensure the normal running of the warp and the tension stretching of the warp, the arrangement of the warp usually does not cover the entire sizing roller, and there is still a large gap between the border warp and the inner surface of the frame.

[0005] Although the waterproof cover has been set up now, in practical application at present, when the sizing tank of the sizing machine is running at high speed, it is easy to throw the sizing forward from both ends. After high-temperature drying, starch particles are formed on the warp yarns. During the weaving process, when the warp yarns pass through the fabric, the starch particles are prone to warp breaks

Moreover, most of the sizing process is to send the yarn directly into the sizing tank to immerse in the sizing solution, which also causes extremely uneven sizing. After the yarn comes out, due to the excessive sizing solution attached to the yarn, it is transported to the dryer for rapid drying and appears. The freezing point of the slurry directly leads to the reduction of product quality and grade
