Abstract

The invention provides polylactic acid forming paper adopting polylatic acid fibers as a raw material and a preparation method thereof so as to solve the vices of hair slip and powder drop of the conventional forming paper and reduce excessive consumption of production of the conventional forming paper on resources to a certain extent. The invention adopts the following technical means: the polylactic acid forming paper comprises the following components in parts by weight: 15-65 parts of polylactic acid fibers, 15-20 parts of hardwood fibers with whiteness of 80-85% and 10-15 parts of polyester fibers, wherein the polylactic fibers are 4-6 mm long, and the fineness is 1-5 D; the polyester fibers are 4-10 mm long and the fineness is 0.5-1.4 D; the ratio of the forming paper is 10-50 g and the air permeability is 500-50000 um / pa.s.

Description

technical field [0001] The present application relates to the field of preparation of cigarette paper, in particular to the field of preparation of shaped paper. Background technique [0002] Forming paper is a kind of thin special paper for industrial use. It is an auxiliary material for cigarettes. It is mainly used to wrap tow in cigarette filters in the tobacco industry, and then use tipping paper to bond cigarettes and filter rods to form filter cigarettes. The main functions of paper are: coating tow, filtering and diluting mainstream smoke, improving taste, and reducing the harm of cigarettes to human body. [0003] The existing forming paper is the same as the ordinary papermaking industry. The raw material used is mainly wood fiber, which consumes a lot of forest resources. With the rapid increase in market demand for high-quality and high-grade paper products, the demand for wood pulp is growing rapidly. Domestic raw materials are in short supply and have to rely ...
