Problems solved by technology

Although the equipment can independently control the temperature and pressure of the autoclave 11 and the low-pressure autoclave 12, it needs two kettle bodies, which are bulky and take up a lot of space. There are many places where leakage occurs, which increases production risks and safety hazards

Abstract

The invention discloses flash spinning equipment. The equipment mainly comprises a high pressure kettle, a heating sleeve of the high pressure kettle, a transmission motor, a stirrer, a high voltage electric valve and a spinning nozzle, and is characterized in that: a kettle cover of the high pressure kettle is provided with a pressure relief hole and a pressure relief valve, so the high pressure kettle simultaneously has the functions of a low pressure kettle; and the bottom of the high pressure kettle is in direct pipe connection with the spinning nozzle through the high pressure electric valve. The flash spinning equipment has the advantages of simple structure, easy control and the suitability for industrial use.

Description

technical field [0001] The invention relates to a spinning device, which belongs to the technical field of chemical fibers, in particular to a flash spinning device for spinning superfine fibers by a flash method. Background technique [0002] Microfiber is a high-quality, high-tech and high-value-added new textile raw material. The textiles made of it have light and thin texture, soft and comfortable feel, good drapability, large specific surface area, strong adsorption, and warmth retention. It is widely used in many fields because of its excellent performance, waterproof and breathable performance. The preparation methods of ultrafine fibers generally include: composite spinning stripping method, dissolution method, super stretching method, melt blown method and flash evaporation method. [0003] One disclosed form of flash spinning microfiber apparatus (see U.S. Patent No. 3,860,369 and figure 1 ), mainly including a high-voltage chamber 1, a low-voltage chamber 2, a s...
