Problems solved by technology

[0004] These above-mentioned production methods all can't break away from the craft of first forming bamboo slices and then forming bamboo fiber bundles. The processing technology is relatively backward, the production efficiency is low, and the waste of processing materials is serious. It is impossible to process the whole bamboo in an assembly line to achieve efficient large-scale production.
Moreover, the current preparation method does not make full use of the overall interconnection of bamboo stalks (raw bamboo) to facilitate fiber opening, and it is difficult to solve the bamboo fiber processing problems caused by the large degree of bamboo tapering and the wide variety of shapes and sizes, resulting in the production of bamboo fibers. The quality is poor, the fiber is thick, short and hard, and its uniformity, length, fineness, strength and other indicators cannot meet the requirements for the use of bamboo fiber in textiles and other industrial fields

Embodiment 1

[0039] Step 10: Choose three-year-old moso bamboo or Ci bamboo or green bamboo or Ma bamboo or Qingpi bamboo and other bamboo materials.

[0040] Step 11: Perforate with a perforator or other methods, or cut the cylindrical bamboo into two halves with a machine tool, so that the bamboo becomes a hollow cylindrical (conical) tube shape or a semi-cylindrical (conical) tube shape, so that the softening liquid enters the bamboo Inside the cavity, sodium hydroxide in the softening solution: 80g / l, sodium carbonate 180g / l, sodium sulfite 45g / l, sodium silicate 45g / l or waste alkali solution (alkali content 12%), and completely immerse the bamboo in In the softening solution, place it at room temperature for 15 days, or heat it to 90-100°C and keep it warm for 1-5 hours.

[0041] Step 12: Soak the softened bamboo in the designated cleaning pool for 15 minutes, then rinse and send it to the area to be processed to dry, then send the dried bamboo to the continuous mechanical processing...

Embodiment 2

[0051] Step 30: Choose bamboo materials such as annual Moso bamboo or Ci bamboo or green bamboo or Ma bamboo or green bamboo.

[0052] Step 33: Send directly to the continuous mechanical processing area, through heating and baking or without heating and baking, and send it to the flattening area with the help of feeding force, using a special mold to split the lower edge of the front end of the bamboo first and then gradually flatten.

[0053] Step 34: After the bamboo is flattened, it is combed, and then the bamboo is formed into a fiber bundle by a fiber-opening separator.

[0054] Step 35: After airflow classification, the bamboo tow fibers are further classified by vibrating conveyor belt and winnowing grading system to remove ultra-short fibers and powder particles to obtain bamboo fiber bundles with uniform length and fineness.

[0055] Step 36: Put the bundle of fibers in a cooking pot (pool) and heat for 60 minutes. The temperature during scouring is 70° C., the bath r...

Embodiment 3

[0061] Step 50: Select two to five-year-old moso bamboo or citron bamboo or green bamboo or hemp bamboo or green bamboo and other bamboo materials.

[0062] Step 51: Use a perforator or other methods to perforate the bamboo into a hollow cylindrical (conical) shape, so that the softening liquid can enter the bamboo cavity. The softening liquid is the spent scouring liquid used in Embodiment 1 and Embodiment 2. , or the scouring solution used in step 56 of the present embodiment, or the mixed solution of the two above, etc., and the bamboo is completely immersed in the softening solution, placed at room temperature for a certain period of time (60 days) or heated to 90~100 ° C, Keep warm for 5 hours.

[0063] Step 52: Soak the softened bamboo in a designated cleaning pool for 15 minutes, then rinse and send it to the area to be processed to dry, then send the dried bamboo to the continuous mechanical processing area for processing, and then heat and bake.

[0064] Step 53: Sen...

Abstract

The invention discloses a process for producing a bamboo fiber, comprising the following steps of selecting raw materials, extending, splitting, classifying, stewing and cooking, pickling, cleaning, dehydrating, curing and the like, thus preparing the bamboo fiber with the fineness of 0.03-0.08mm and the length of 30-80mm. The process can lead a whole bamboo to be extended by a special tool and subsequently and directly processed without being cut; furthermore, the processed bamboo fiber is longer, finer and more uniform, the utilization ratio of the resource is high, the cost is low and the quality of the product is stable.

Description

【Technical field】 [0001] The invention relates to a bamboo processing technology, in particular to a production technology for directly producing bamboo raw fibers with bamboo stalks (raw bamboo). 【Background technique】 [0002] The preparation of bamboo fiber by mechanical, physical, biochemical and other methods is a current hot topic and the development trend of new industries in the future. [0003] In recent years my country has had many invention patents on the raw bamboo fiber manufacturing method, and CN11078520C has announced a kind of manufacturing method that raw bamboo is opened, rolled, and forms bamboo fiber bundle products, and CN1261290C has announced a kind of using pure The physical method is to separate the filaments by cooking, remove sugar, fat, protein, and starch, and then mechanically impact, tear, and open into bamboo fibers. CN1185086C has announced that by processes such as cold rolling, boiling, soaking, dehydration and combing fibers, the fibers ...
