An embodiment of the invention discloses an agilawood fragrance style dry-method slice preparation method which can effectively reduce the content of wood gas and harmful substances in a dry-method slice so as to enable the dry-method slice to have a strong agilawood fragrance style. The method comprises the following steps: soaking tobacco stems in water to obtain soaked tobacco stems; carrying out bio-enzyme processing on the soaked tobacco stems, and drying the processed tobacco stems to obtain the tobacco stems subjected to the bio-enzyme processing; laying the tobacco stems subjected to the bio-enzyme processing onto a forming net after mechanical fiber separating to form a fiber thin layer; spraying chitosan adhesive on the surface of the fiber thin layer and carrying out drying to obtain a dry-method slice substrate; spraying aloewood powders on the surface of the dry-method slice substrate; spraying cigarette powders on the surface of the dry-method slice substrate; spraying chitosan on the surface of the dry-method slice substrate; and then, carrying out drying to finally obtain the dry-method slice which has the strong agilawood fragrance style, and of which the content of the harmful substances is reduced.

The invention discloses a hemp fiber freezing radiation auxiliary de-gumming technique, comprising the following steps of undergoing UV radiation, quenching, and heating treatment after hot bath, acidpre-etching, and pre-chlorination, and then undergoing base oxygen-mechanical associative de-gumming treatment, finally adding a softener for secondary scouring. The hemp fiber surface de-gumming effect treated by the technique is prior to ordinary base oxygen method and mechanical de-gumming, and the former meets the requirement of product of national first grade; the lignin content meets requirement of finishing technique after spinning, which obtains good whiteness and flexibility, and controls breaking strength and tensile stretch of fiber in requirement of spinnability, with improved length and fineness of fiber is improved, greatly improved serviceability, and less pollutant effluents discharged, so that the invention is environment-friendly.

The invention discloses a fibrilia cryogenic-machinery combined degumming processing method. The method comprises: after preprocessing, performing cryogenic treatment on hemp fibers, rapidly heating to normal temperature status, and degumming in a mechanical beating method, performing water processing, and drying for standby application. Processing of pectin and hemicellulose and other impurities makes the hemp fibers treated by the process satisfy to be used as a fiber reinforced base, and in use, VOC emission reaches national requirement, and the hemp fiber also reaches requirement of being used for weaving. Processing the fibrilia by the method improves usability of fibers, and sewage discharge is little, and the method is an efficient environmentally-friendly process. The fibrilia made by the method is good in fiber quality, and fiber surface is concave-convex and is beneficial for combining with an interface of a matrix. The fibrilia is good in degumming effect and wide in purposes, and can be widely used for fiber-reinforced-based fibers, and can be used for spinning industry. The method has good application prospect.

A biological additives to expand tobacco and its producing method and applications are disclosed whose compositions and contents are tobacco leaf protein degradation enzyme of 0.1-10%, starch degradation enzyme of 1.0-10%, pectin degradation enuzyme of 0.2-10%, polyose degradation enzyme of 0.5-20%, fiber modifier of 0.5-20%, polyphenol oxidation degradution enzyme of 0.1-5%, carbon chain enzyme of 0.1-10%, vitamin C of 0.1-5% and water of 100%. The invented additives can be added into tabocco after the tabocco is remoistened and cut into pieces but before the tabocco is expanded with adding quantity as 0.2-5% of tobacco pieces weight at the temperature of 30 degree c to 50 degree C. The present invention can not bring negative influence to tobacco but can decrease the composition contents which is harmuful in smoking.
