Production and processing method of medical melt-blown non-woven fabric

Abstract

The invention relates to a production and processing method of medical melt-blown non-woven fabric. The production and processing method of the medical melt-blown non-woven fabric comprises a base plate, supporting frames and a melt-blowing device, wherein the supporting frames are symmetrically mounted at the upper end of the base plate, and the melt-blowing device is mounted between the upper ends of the supporting frames. By the adoption of the production and processing method of the medical melt-blown non-woven fabric, the problems that when an existing device is used for processing melt-blown non-woven fabric, the air speed during melt blowing cannot be accurately regulated generally, hot air cannot be effectively and uniformly dispersed during melt-blowing, and consequentially, the thickness distribution of fibers after melt-blowing is not uniform, and the subsequent usage effect of the non-woven fabric is affected; and meanwhile, when the existing device is used for processing the melt-blown non-woven fabric, melt-blown polymers cannot be effectively, uniformly and rapidly mixed generally, and consequentially, the melt-blown polymers are likely to be layered, and the qualityand effect of the non-woven fabric are affected are solved.

Description

technical field [0001] The invention relates to the field of processing medical melt-blown non-woven fabrics, in particular to a production and processing method of medical melt-blown non-woven fabrics. Background technique [0002] As disposable sanitary products are favored by consumers, the non-woven fabric layer used for the surface layer of disposable sanitary products is also favored by consumers due to its simple production process, large output, low cost, softness and skin-friendly. Note that melt-blown non-woven fabrics are usually blown into fine fibers by the thermoplastic resin melted from the spinneret after the thermoplastic resin passes through the extruder. Non-woven fiber, because of its one-step production process, saves costs, and the formed fiber is thinner, soft and comfortable, and is suitable for disposable sanitary products. [0003] At present, the existing melt-blown non-woven fabrics usually have the following defects in the production and process...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot effectively adjust the wind speed during the melt blown process accurately when processing the melt blown non-woven fabric, and cannot effectively spread the hot air evenly during the melt blown process, resulting in The uneven distribution of fiber thickness after melt-blowing affects the subsequent use of non-woven fabrics. At the same time, when the existing equipment is processing melt-blown non-woven fabrics, it is usually not able to effectively and uniformly mix the molten polymer quickly, resulting in The polymer after meltblown is prone to delamination, which affects the quality and effect of non-woven fabrics and other problems
