Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile production equipment, in particular to a circulating drying room device for melt-blown drying. BACKGROUND

[0002] The melt-blown non-woven process is a kind of polymer extrusion webbing method, which originated in the 1950s. Since then, the melt-blown process has been continuously developed. Melt-blown non-woven materials have excellent performance in filtration, antibacterial, adsorption, warmth retention, and waterproofness, which cannot be matched by other non-woven materials. Melt-blown materials are quickly applied to various industries. The principle of melt-blown process is to extrude polymer melt from the spinneret orifice to form a stream, and the heated stretching air is blown out from the air gap on both sides of the spinneret orifice at high speed to stretch the polymer melt stream. The cooling air is supplemented from both sides at a certain position below the spinneret to cool and crystallize the fibers. A vacuum suction device is provided below the webbing curtain of the receiving device to uniformly collect the ultra-fine fibers formed by high-speed air flow on the webbing curtain of the receiving device, and to become melt-blown non-woven materials by self-bonding or other reinforcement methods.

[0003] Melt-blown filtration materials can form a fiber web by self-bonding due to their ultra-fine fiber diameter and ultra-dense porosity, and almost no additional reinforcement method is needed to become a non-woven fabric with certain strength. Melt-blown fibers are stretched by hot air, although the fibers are cooled by cold air, but there are still small droplets between the entangled fibers, which will affect the overall performance of the material. Therefore, the drying device is very important for melt-blown materials.

[0004] The air flow in the commonly used melt-blown drying device is unidirectional, which will make the melt-blown material soft or hard during drying, affecting the entanglement and point-like cross structure between fibers, thereby causing the performance of melt-blown non-woven fabric to decline. The use of unidirectional air flow also makes the production cost high, causing waste of resources. In addition, the air flow is easy to distribute unevenly, which will also make the melt-blown material soft or hard.

[0005] Therefore, it is necessary to design a circulating drying room device for melt-blown drying to solve the above problems. Invention content
