Problems solved by technology

[0005] In recent years, bamboo fiber production methods have been continuously introduced, but they are all inseparable from the traditional strong alkali scouring, rubbing and cracking and other external force methods, which greatly damage the fiber cells, resulting in low extraction rate, poor quality and high energy consumption of bamboo fiber. , serious pollution and waste

Embodiment 1

[0026] Step 1: Slicing and slicing: cutting the bamboo into slicing and slicing, and processing it into bamboo filaments with an equivalent diameter of 0.5mm;

[0027] Step 2: Vacuuming: drying the bamboo silk at a temperature of 60°C for 2h, the vacuum degree is 0.1MPa;

[0028] Step 3: Soaking and rolling: soak the bamboo silk in a saturated solution of baking soda, and roll it for several times, and then dry the bamboo silk. Time 3h, water temperature 40℃, baking soda accounted for 15%;

[0029] Step 4: Swelling and steaming: make alum into a paste, roll into bamboo silk for several times, and then steam at 100°C for 30min;

[0030] Step 5: washing and dehydration: washing to remove lignin and other impurities, dehydration and drying to obtain crude bamboo fibers (which can be directly used for composite material preparation).

Embodiment 2

[0032] Step 1: Slicing and slicing: cutting the bamboo into slices and slicing, and processing them into bamboo filaments with an equivalent diameter of 0.1 mm;

[0033] Step 2: Vacuuming: drying the bamboo silk at a temperature of 50°C for 1h, the vacuum degree is 0.08MPa;

[0034] Step 3: Soaking and rolling: soak the bamboo silk in a saturated solution of baking soda, and roll it for several times, and then dry the bamboo silk. Time 1h, water temperature 20℃, baking soda accounted for 10%;

[0035] Step 4: Expansion steaming: make alum into a paste, roll into bamboo silk for several times, and steam at 80°C for 10min;

[0036] Step 5: cleaning and dehydration: cleaning to remove lignin and other impurities, dehydration and drying to obtain thick bamboo fibers;

[0037] Step 6: Drying and Carding: The thick bamboo fibers are dried and sent to a carding machine to make bamboo fibers for textile raw materials.

Abstract

The green production method of bamboo fiber uses the principle that baking soda and alum react in water to generate a large amount of carbon dioxide, and internally expands and cracks bamboo threads, thereby thinning the bamboo threads to obtain bamboo fibers. In the present invention, the thick bamboo fiber suitable for composite materials and the bamboo fiber used as textile raw materials are prepared by processing bamboo material into bamboo silk, and food-grade baking soda and alum are used as auxiliary agents in the preparation process to minimize pollution and achieve energy-saving and green production.

Description

【Technical field】 [0001] The invention belongs to the field of bamboo fiber production, and in particular relates to a preparation method for green production of bamboo fiber. 【Background technique】 [0002] Bamboo industry is a globally recognized green and ecological industry with huge economic, ecological, cultural and social value. Bamboo industry is a sustainable ecological industry, not only will not destroy the ecology, but can promote the increment of resources and ecology, bamboo fiber production technology is at the core of the innovation and development of the bamboo industry. [0003] Bamboo fiber (natural bamboo fiber, also known as bamboo fiber) is a new type of plant fiber. It is a natural fiber directly separated from bamboo. It is different from chemical bamboo viscose fiber (bamboo pulp fiber, bamboo charcoal fiber). It is the fifth largest natural fiber after hemp, silk and wool. [0004] The chemical composition of bamboo is mainly composed of cellulose...
