Abstract
The invention discloses a preparation method of polylactic acid fiber cigarette tows. The preparation method comprises the following steps of: drying polylactic acid and extinction master batches respectively; perform blending spinning; and performing drafting, curling, baking shaping and the like to obtain the polylactic acid fiber cigarette tows. The production method provided by the invention can be used for preparing polylactic acid fiber tows on a domestic comparatively mature production device of the polylactic acid fiber cigarette tows at present; a filter stick produced from the polylactic acid fiber tows has an obvious effect in filtering harmful substances in smoke gas and can meet a special requirement on cigarettes; and the polylactic acid fiber cigarette tows are completely biodegradable and environment-friendly, and can replace acetate fiber tows used in high-medium grade cigarettes.
Description
Technical field
The present invention relates to a kind of preparation method of pipe tobacco, be specifically related to a kind of preparation method of acid fiber by polylactic pipe tobacco.
Background technology
Cigaratte filter improves the cigarette grade and plays great role reducing tar and reducing harm, is an indispensable part in the production of cigarettes process.Cigarette filter tip material in the market mainly contains two kinds, and the one, acetate silk, the 2nd, polypropylene fibre tow.The filter rod combination property that acetate silk is produced is superior, be mainly used in medium-to-high grade cigarette, but acetate silk is that the cellulose acetate with the production of high-quality timber is a raw material, and complex manufacturing, investment be big, cost an arm and a leg, and production process is also easily brought environmental pollution.The forest reserves of China are limited, and lumber quality also is not suitable for producing cellulose acetate, annual a large amount of import cellulose acetates and the acetate silk of needing.And in recent years, enhancing day by day along with serious day by day and people's environmental consciousness of deforestation, high-quality timber producing countries such as Canada have begun to limit deforestation, thereby make being becoming tight supply day of interior cellulose acetate of worldwide and acetate silk, this has determined the acetate fiber filter rod not use in a large number in low and middle-grade cigarettes.On the other hand, cellulose itself can be degraded, but after the acetic acid esterification, biodegradability descends to some extent, no longer belongs to proper degradable material.Polypropylene fibre tow source is abundant, and production process is simple, and price is lower, but because the design feature of polypropylene fibre itself, the filter rod combination property of production is relatively poor, can only be used for low-grade cigarette.Polypropylene fibre can not biodegradation, a large amount of use, and the discarded object of generation is unfavorable to environment.
In recent years, biodegradated polymer materal has had fast development, lactide acid polymer particularly, as PLA, the polymer of lactic acid and glycolic etc. are under field conditions (factors) or under people's concrete conditions in the establishment of a specific crime, biodegradation can take place, finally becoming carbon dioxide and water, do not stay any pollutant, is genuine environmental friendliness, green material.PLA is a kind of biodegradable novel high polymer material, be that to produce the lactic acid product be raw material through modern biotechnology with crops such as corn, sugarcane, potato, sweet potatoes, pass through the macromolecular material that special polymerization process generates again, its raw material is reproducible plant resources, and raw material sources are abundant, cheap.And acid fiber by polylactic is obvious to harmful substance filter effect in the flue gas, can reach the specific (special) requirements of cigarette, possesses the good condition as novel pipe tobacco.
Research report about textile acid fiber by polylactic and goods thereof is more, but the performance of textile acid fiber by polylactic can not satisfy cigarette with requiring, and can not be used for cigarette filter production; Less about cigarette with the research report of acid fiber by polylactic aspect, and be in the laboratory research state, equipment, raw and auxiliary material and working condition to be had relatively high expectations, its preparation method and suitability for industrialized production also have certain distance, and properties of product also remain further perfect.
Summary of the invention
The objective of the invention is to provide a kind of low, can carry out the preparation method of the acid fiber by polylactic pipe tobacco of suitability for industrialized production the working condition requirement.
The object of the present invention is achieved like this: a kind of preparation method of acid fiber by polylactic pipe tobacco may further comprise the steps:

(2) with dried PLA and delustring master batch, by weight, PLA 97-99.5 part and delustring master batch 0.5-3 part are carried out blend, blend carries out melt spinning at 180-250 ℃, and carries out cooling forming with 15-30 ℃ ring blowing or cross air blasting;
(3) in continuous spinning process, spinning oil is coated to the acid fiber by polylactic surface by the finish oil disc that rotates;
(4) with drafting machine acid fiber by polylactic is carried out drawing-off;
(5) will curl through the tow of drawing-off;
(6) tow after will curling carries out drying and shaping, obtains the acid fiber by polylactic pipe tobacco.
