Problems solved by technology

[0003] The thickness of the existing writing paper is limited. Due to the good water absorption of wood fiber, the ink is easy to permeate, and the paper is thin and lacks texture. The calligraphy works that want to be preserved need to be thickened and mounted.
At the same time, its main raw material wood fiber resources are limited and the price is relatively high.

Abstract

A method for preparing non-woven writing paper, the preparation method comprising the following steps: preparing materials: mixing polyester fibers or mixed fibers containing more than 80 wt% polyester fibers; carding into a web: carding fiber pairs; The fibers are interlaced to form a polyester fiber web, sizing: sizing the polyester fiber web, and the slurry is prepared from adhesives, waterproofing agents and water; drying: drying the sized polyester fiber web to obtain non-woven writing paper . The above technical proposal adopts polyester fiber as a raw material to prepare non-woven writing paper. When the non-woven writing paper is 60g, the thickness is 34-38mm (100 sheets), the paper surface is flat, the paper has toughness, and it is not easy to seep through during the writing process.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a non-woven writing paper and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, refers to the cloth made without traditional spinning, weaving or knitting. It is a new type of fiber product with soft, breathable and planar structure, which is formed into a net, then consolidated by spunlace, needle punching or hot rolling, and finally finished. [0003] The thickness of the existing writing paper is limited. Since the wood fiber has good water absorption, the ink is easy to penetrate, and the paper is thin and lacks texture. Calligraphy works to be preserved need to be thickened and mounted. Simultaneously its main raw material wood fiber resource is limited, the price is higher. With the current economic development in my country, there are more and more discarded fabrics and chemical polyester fibers, and chemical fiber re...
