Description

TECHNICAL FIELD

[0002] Melt-blown non-woven fabric is a kind of high-efficiency filter material produced by melt-blown process, mainly made of polypropylene and other high molecular materials, which can be used to produce medical masks, oil absorption pads, etc.

[0003] In the melt-blown process of non-woven fabric, the polypropylene particles in the hopper are first heated and melted into a melt. Under a certain pressure, the melt passes through the small holes of the spinneret to form fine filaments. The ejected fine filaments immediately encounter a high-speed cold air stream and rapidly cool and solidify, forming ultra-fine fibers. The ultra-fine fibers form non-woven fabric on the collecting device. Finally, the non-woven fabric is wound onto the winding roller for storage and further processing.

[0004] However, since melt-blown non-woven fabric is formed by random arrangement of fibers under the action of high-speed airflow, and the bonding between fibers mainly relies on adhesive or hot melt bonding, this bonding is relatively weak, so melt-blown non-woven fabric is relatively fragile. In addition, when winding melt-blown non-woven fabric, the non-woven fabric between adjacent layers may slide, causing the core of the non-woven fabric and the winding roller to gradually deviate, affecting use and subsequent processing, so a melt-blown device for non-woven fabric is needed to solve the above problems.
