Technical Field

The invention relates to the technical field of non-woven fabric production, in particular to a non-woven fabric production process.

Background

The non-woven fabric is also called non-woven fabric, is formed from oriented or random fibre, is a new generation of environment-protecting material, and has the characteristics of moisture-proofing, air-permeability, flexibility, light weight, no combustion-supporting, easy decomposition, non-toxic, non-irritating, rich colour, low cost and can be cyclically reused, for example, it is made up by using polypropylene granules as raw material through the processes of high-temp. melting, spinning, laying, hot-pressing and coiling, and can be called as cloth because of its appearance and some properties.

The existing non-woven fabric is extremely easy to be pasted with the filter element due to lack of relative cooling measures in the injection process due to high-temperature melting in the production process, so that the production efficiency is influenced, the thickness of the existing non-woven fabric is thicker in the use process, the density is lower, the processing steps are relatively complex, the processing time is longer, the processing speed is reduced, and the processing efficiency is reduced.
