What steps did the ancient papermaking process include?

Degumming of phloem plants and subsequent processing into finer phloem fibers, like the bleaching process of silk cotton, provided technical reference for the invention of papermaking? Through the analysis of ancient paper and referring to the traditional manual papermaking technology, the ancient papermaking technology should include the following steps: 1. Raw materials such as ramie are washed and chopped; Secondly, soak the chopped raw materials in lime or plant ash's alkaline aqueous solution to remove pectin? Pigment and lignin; Thirdly, mashing the degummed fiber into slurry; Fourth, wash the cellulose that has been mashed into pulp repeatedly, then make it into cotton wool, make a layer of fiber sheet with bamboo mat or screen, and dry it in the sun or make paper?

The above paper-making technology has basically been included in retting? In the process of flossing, it is conceivable to invent papermaking, inspired by the frequent occurrence of silk scraps and hemp strands?
