Problems solved by technology

[0006] These patents basically use alkaline chemicals to soften the bamboo in the fiber preparation process, and then the separated bamboo fiber bundles will bring the softening solution into the subsequent process. In the fiber cleaning, the chemicals enter the cleaning solution, so that the discharge during processing Wastewater contains a large amount of pollutants and brings serious environmental problems
Obviously, these methods are difficult to meet the requirements of the current sustainable green production concept
It not only brings a lot of pollutants, but also greatly increases the production cost

Embodiment Construction

[0026] Such as figure 1 Described, a kind of pollution-free production bamboo fiber method that the present invention relates to, comprises the following steps:

[0027] Step 1 Raw materials are selected, and each batch of bamboo is classified according to the place of origin and bamboo age, and stored in each designated area;

[0028] Step 2. Cutting off, sawing off the tip, middle and head of the bamboo according to the specified length. Generally, the sawing length can be within the range of 1-6 meters;

[0029] Step 3. Cutting or flattening, the truncated bamboo is cut in half or divided into 1 / 4 pieces, or the bamboo is directly unfolded into sheets with a flattening machine;

[0030] Step 4. Cooking. Send the split or flattened bamboo to a special high-temperature and high-pressure cooking pot, add water or secondary softening solution, and completely immerse the bamboo in the solution. The cooking temperature is controlled at 100-130°C. Press to 2-3kg / cm2, cook for 10...

Abstract

The invention provides a non-pollution production method of bamboo fibers, wherein the method is used for producing coarse bamboo fibers with lengths of 60-120 mm and diameters of 0.18-0.35 mm. the method comprises the steps of: firstly, selecting the raw materials; and then, cutting the bamboos into regulated lengths; splitting or flattening the bamboos; adding a reusable neutral softening solution in the bamboos to stew and soften the bamboos; roasting the softened bamboos on a drying machine; directionally opening fibers from the roasted bamboos; drying the bamboos, opening fibers for the second time, classifying and sorting to obtain bamboo fibers with stable quality. The method of the invention has the advantages of non waste liquid drainage during the production process, simple technique, high production efficiency, reliable product quality, and capability of greatly improving the fiber yield and reducing the production cost, so that the method is an ideal method for producing bamboo fibers.

Description

【Technical field】 [0001] The invention relates to a method for producing bamboo fiber with no pollution and high efficiency by using bamboo stalks as raw materials. 【Background technique】 [0002] Coarse bamboo fiber refers to bamboo fiber bundles with an average length of 8 cm and a diameter of about 0.3 mm. Because of its high strength, good rigidity, outstanding hygroscopicity and antibacterial properties, it is widely used in the manufacture of automotive interior material panels, mattresses and building decoration material panels. [0003] Extracting bamboo fiber from bamboo has opened up a new way for the deep processing and application of bamboo, and has attracted widespread attention in the international market. The raw material of bamboo fiber comes from natural renewable resources, and the product is biodegradable after use, which meets the requirements of environmental protection and is a new material with broad prospects. [0004] Natural bamboo fiber, also kno...
