Problems solved by technology

[0007] Chinese patent application 98802490.X discloses a kind of equipment and method for producing stretched synthetic filament, which uses polyethylene terephthalate (PET) as raw material, and obtains long yarn through spinning device, heating device and stretching device. Because a heating device is set between the spinning device and the drawing device, the obtained filament has higher strength and lower elongation, but due to the setting of the heating device, the equipment and process are more complicated. At the same time, it still only obtains filaments, which does not achieve the purpose of one-step cloth formation, and does not describe in detail the further processing into non-woven fabrics
[0010] Polyamide fiber (trade name nylon) has become a good raw material for non-woven fabrics because of its good softness, high strength, wear resistance and other properties, but it is currently impossible to use polyamide raw materials to make nylon non-woven fabrics

Embodiment 1

[0033] As shown in Figure 1, the polyamide 6 (PA6) slices are placed in the drying system 1 and dried with hot air at 130°C, and sent to the hopper 2 through the air conveying device, where the PA6 slices are mixed with various additives (such as brighteners, coloring additives and various additives) are fully mixed and sent to the screw extruder 3 for extrusion and melting. The temperature of the extruder is 250°C. After several stages of feeding, compression and metering, the materials are fully melted and mixed Finally, it is sent to the filter 4, where the impurities in the material, such as carbon, ash, etc., are filtered out, and the material enters the metering pump 6 through the melt pipeline 5, and the metering pump evenly and accurately melts the molten material through the distribution pipeline 7. Distributed to each spinning position, the temperature of the melt pipe and the distribution pipe is kept at about 250°C.

[0034] Spinning is carried out in the spinning ...

Embodiment 2～4

[0037] Technological process and equipment are basically the same as embodiment 1, and technological conditions are shown in Table 1:

[0038] Table 1 Nylon non-woven fabric process conditions

[0039] screw extrusion

[0040] The nylon non-woven fabric products obtained by the above process have the characteristics of soft hand feeling, high strength, high elastic recovery rate and bending resistance.

Abstract

The spinning-bonding process of producing non-woven Jinlun cloth with polyamide as material includes drying material, extruding fusion, filtering, spinning, cooling, drafting yarn separating to spread net, hot rolling and winding. The non-woven Jinlun cloth product of the present invention has soft hand feeling, high strength, good wear resistant performance, high resilience, and strong fatigue resistance and thus wide use.

Description

technical field [0001] The invention relates to a process for producing nylon nonwoven fabric by using polyamide as raw material and adopting a spun-bonding method. [0002] The invention also relates to equipment for producing nylon non-woven fabric by spun-bonding method. [0003] The present invention also relates to a nylon non-woven fabric product manufactured by the above process and equipment. Background technique [0004] The production of non-woven fabrics can use various raw materials, various methods, and obtain products with different properties. [0005] In the prior art, the production of non-woven fabrics generally includes two processes. First, the raw materials (polymers) are melt-spun to obtain filaments, and then the filaments are further processed into short fibers, and then the long filaments are processed into short fibers. Silk or short fibers are used as raw materials and bonded by hot rolling to make non-woven fabrics. The whole process often requi...
