Embodiment 1

[0026] Example 1: Glass fiber, chlorinated polyvinyl chloride fiber, jute fiber and spandex fiber are mixed according to the ratio of 1:4:3:5, the raw materials are dried and the drying temperature is controlled at 40°C, and then melted into the spinning In the silk machine, the nylon staple fiber web can be obtained through clustering, stretching, shaping, crimping and packaging. The nano-copper oxide is covered on one side of the nylon staple fiber web, and the reinforcing agent is sprayed on the side of the nylon staple fiber web covered with nano-copper oxide. On one side, use a sprayer to spray the high-speed iron glue additive between the nylon staple fiber net and the foam dressing, so that the high-speed iron glue additive can penetrate into the nylon staple fiber net and foam dressing evenly, and put the nylon staple fiber net into the vibration machine Vibration mixing is carried out in the middle, so that the high-iron glue additive and the foam dressing evenly enter...

Embodiment 2

[0027] Embodiment 2: Embodiment 1: glass fiber, chlorinated polyvinyl chloride fiber, jute fiber and spandex fiber are mixed according to the ratio of 1:4:3:5, and the raw materials are dried and the drying temperature is controlled at 50°C. After melting, it enters the spinning machine, and then through clustering, stretching, shaping, crimping and packaging, the nylon staple fiber web can be obtained. The nano-copper oxide is covered on one side of the nylon staple fiber web, and the reinforcing agent is sprayed on the nylon staple fiber web. On one side of the nano-copper oxide, use a sprayer to spray the high-iron glue additive between the nylon staple fiber net and the foam dressing, so that the high-iron glue additive can penetrate into the nylon staple fiber net and the foam dressing evenly, and the nylon staple fiber net Put it into a vibrating machine for vibration mixing, so that the high-iron glue additive and foam dressing evenly enter the nylon staple fiber web. Du...

Embodiment 3

[0028] Embodiment 3: Embodiment 1: glass fiber, chlorinated polyvinyl chloride fiber, jute fiber and spandex fiber are mixed according to the ratio of 1:4:3:5, and the raw materials are dried and the drying temperature is controlled at 60°C. After melting, it enters the spinning machine, and then through clustering, stretching, shaping, crimping and packaging, the nylon staple fiber web can be obtained. The nano-copper oxide is covered on one side of the nylon staple fiber web, and the reinforcing agent is sprayed on the nylon staple fiber web. On one side of the nano-copper oxide, use a sprayer to spray the high-iron glue additive between the nylon staple fiber net and the foam dressing, so that the high-iron glue additive can penetrate into the nylon staple fiber net and the foam dressing evenly, and the nylon staple fiber net Put it into a vibrating machine for vibration and mixing, so that the high-iron glue additive and foam dressing evenly enter the nylon staple fiber web...

Abstract

The invention provides a production method of a waterproof and leakproof non-woven fabric for high-speed railway foundation, which comprises the following steps of: mixing glass fiber, chlorinated polyvinyl chloride fiber, jute fiber and spandex fiber in a ratio of 1:4:3:5, drying and melting the raw material, putting the raw material into a spinning machine, and bundling, stretching, shaping, crimping and packaging the raw material to obtain a nylon short fiber web; coating one side of the nylon short fiber web with nano-copper oxide, and spraying a reinforcing agent on the one side of the nylon short fiber web coated with the nano-copper oxide; and coating the part between the nylon short fiber web and a foam dressing with a high-speed railway glue additive by a coating machine, so thatthe high-speed railway glue additive uniformly penetrates into the nylon short fiber web and the foam dressing. By the addition of the high-speed railway glue additive, the waterproof and leakproof function is achieved; by the addition of the nano-copper oxide, the anti-static function is achieved; and by matching with the foam dressing, the jute fiber and the spandex fiber, the performance of thewaterproof and leakproof non-woven fabric for the traditional high-speed railway foundation is further improved.

Description

technical field [0001] The invention relates to a production method of a waterproof and anti-leakage nonwoven fabric for high-speed rail foundations, belonging to the field of textiles. Background technique [0002] In the prior art, high-speed rail has different regulations in different countries, different eras, and different research and academic fields. The National Railway Administration of China defines China's high-speed railways as passenger train-dedicated railways with a design speed of 250 kilometers per hour or more (including reservations) and an initial operating speed of more than 200 kilometers per hour, and issued the corresponding "High-speed Railway Design Specifications" document. The National Development and Reform Commission of China defines China’s high-speed railways as new or existing railway lines with a speed of 200 kilometers per hour and above, and issued the corresponding “Medium and Long-term Railway Network Planning” document, which will unifo...
