Problems solved by technology

The traditional process consumes a lot of energy, has many pollutants, and costs high because its technical route is mainly to change the primary or secondary structure of natural polymers.
Moreover, it is necessary to separate the main components of the plant and use them separately, which will further increase the energy consumption and the generation of pollutants in the processing and manufacturing process.

example 1

[0033] Inner Mongolia Xianghuang Banner Shoulin Composite Molecular Materials Co., Ltd. modified 65% of wood powder with 5% dry modifier, added 35% of waste plastics, and after stirring, granulated with a single-screw granulator. Polymerized wood piles made by SJ-90 single-screw extrusion have good performance and are ordered by the state for sand prevention and sand enclosure. And in November 2006, it was recognized as a national key new product by the Ministry of Science and Technology, the Ministry of Commerce, the General Administration of Quality Supervision, Inspection and Inspection, and the State Environmental Protection Administration, and a certificate was issued.

example 2

[0035] The Pilot Factory for Modification of Biomass Materials of Beijing Institute of Computer Technology uses cotton stalks as raw materials, and uses dITAN1-4 developed by Inner Mongolia Xianghuangqi Composite Molecular Materials Co., Ltd. for modification to produce solution-modified soft fibers. The pulp is refined by a refiner, and single-stage bleaching is carried out with hydrogen peroxide, and the whiteness reaches 80 degrees. Then use a softener for softening. This fiber was sent to Beijing Textile Science Research Institute, and it was identified as "true plant fibril". The fiber length is better protected and can be used in the textile industry.

example 3

[0037] Guangxi University Paper Research Institute uses bagasse to make plant fibers for papermaking. The experimental data are as follows: the whiteness of bleached pulp is 76.5, and the beating degree is 45 degrees.

[0038] 60 g / m 2 Printing paper, the properties are as follows:

[0039] Fracture length 7.93; tensile index 67.3; tear index 6.67; burst index 2.68; folding resistance 204 times.

[0040] In Henan Wugang Paper Co., Ltd., wheat straw is used for pulping. The whiteness of bleached pulp is 78, the density is 0.18, the degree of beating is 50, the hardness is 60, and the fiber content is 92%.

[0041] Use this wheat straw pulp to produce 200 grams of raw pulp paperboard at Xihuafeng Paper Factory of Huanghe Group, and measure its physical properties: ring pressure CD15KN / m 2 , Fracture length 6, burst resistance 3, folding resistance 60 times, moisture content 9.

Abstract

The invention discloses a plant-modified fibril and a preparation technology thereof, and the plant-modified fibril is obtained by modifying the aggregate state by taking the plant as a raw material. The plant-modified fibril basically reserves the main ingredients of the natural plant, and changes the physical form and the performance of the natural plant, so that the rigid material can be prepared, and the flexible material such as the paper, the fabric and the like can be prepared. The modified fibril is prepared by the working procedure which comprises the following steps of softening, separating, rolling thread, grinding into a thick liquid or pulping, bleaching, softening and the like under normal temperature and normal pressure. The new fibril is wide in raw materials, low in manufacture cost, and outstanding in energy-saving, emission-reducing and consumption-reducing effects. The technology is universal, thereby being applicable to the new factory, the original pulping factory and the original fiber factory. The plant-modified fibril and the preparation technology thereof are low in scale requirement, thereby being especially suitable for the demand of the economic development of the agriculture and the rural area.

Description

technical field [0001] The invention discloses a fibril obtained by using plants as raw materials through aggregation state modification and a manufacturing process thereof. The physical characteristics of this modified fiber are that the main components such as cellulose, hemicellulose, and lignin of natural plants are basically retained, and at the same time, its material form and properties are changed. It can be used to make rigid materials and flexibility. Material. The characteristic of the process of manufacturing this modified fiber is to modify the aggregated state of the plant raw materials through hydrogen bond reaction at normal temperature and pressure or under low or high pressure, so that they can be softened and separated by rolling, refining or beating, Bleaching, softening and other processes are completed. This new fiber has a wide range of raw materials, low manufacturing cost, close to natural ingredients, easy to use, and its manufacturing process saves...
