Abstract
The invention relates to a production process for bamboo fiber, which comprises steps of material selection, fiber splitting, classification, digestion, reduction, acid pickling, cleaning, dehydration, curing and the like. According to the production process, the whole piece of bamboo is directly processed after being flatten by a special tool under the condition of no cutting and splitting, a mode of bamboo eaten and fiber spit is realized, the production process is free from the limitation of bamboo varieties, bamboo age, bamboo joint and bamboo diameter, a heat-force-chemical multi-field coupling principle is adopted in a bamboo fiber splitting separator to make the machined bamboo fiber longer, finer and more uniform than original fiber, edges and unprocessed bamboo are a few, and an additive is added, so that a product has high folding resistance and flame retardance. The production process is reliable, the resource utilization rate is high, the processing cost is low, environmental pollution is low, the product quality is stable, and the problem of high-efficiency mass production of fine and long bamboo pure fiber is effectively solved.
Description
Technical field
The present invention relates to field of textiles, relate in particular to a kind of production technology of bamboo fibre.
Background technology
Countries in the world are all paid close attention to the protection of environment for human survival more at present; Particularly limit the felling of forest; Along with the wood supply amount in a large amount of minimizings; Growing population increases the timber requirement, improve timber utilization rate, to develop other substitution of resources timber resources more and more urgent, various research and developments are all being attempted and are in depth being carried out.For example shaving board, thick particle board, particle board, crops bar stem are processed products such as fiberboard, macromolecule organic, metal, are applied in industries such as building industry, furniture manufacturing industry, packaging material.The bamboo class is a kind of important industrial resources, and universal use is as the making furniture, building materials, artwork ornaments and daily life tools, and deeper development and use are still among research.Now as the building materials aspect, can the production of bamboo laminated board, and be base stock with the bamboo fibre, the technology of production of bamboo fibrous plate replacing wood also is mature on the whole.
The production method of traditional bamboo fibre has all broken away from not the technology that XianCheng's bamboo chip becomes bamboo fiber bundle again, and its process technology is more backward, and production efficiency is low, and the rapidoprint waste is serious, can't carry out streamline processing to realize high-efficiency large-scale production to whole bamboo.And the integral body that present preparation method does not make full use of bamboo stem stalk (former bamboo) connects the fine characteristics of being convenient to out each other; Be difficult to solve the bamboo fiber processing difficult problem that the bamboo taperingness is big, geomery varies and brought; The bamboo fibre that causes being produced is of poor quality; Fiber is thick, short, hard, indexs such as its uniformity, length, fineness, intensity can not reach weaving with and other industrial field to the instructions for use of bamboo fibre.
Summary of the invention
In order to overcome above defective; The technical problem that the present invention will solve is: propose a kind of whole bamboo directly to be processed after flattening through special facility under the situation of hacking without cutting; And the bamboo fibre that processes is longer, more carefully, more even; Resource utilization is high, and is with low cost, has the production technology of the bamboo fibre of good folding resistance.

Step 2: with punch bamboo is bored a hole, or cut away half, make bamboo become hollow cylinder (circular cone) barrel shape or semicolumn (circular cone) barrel shape with the bamboo of facility with cylindrical shape; So that bating liquor gets into inside, bamboo chamber; NaOH in the bating liquor: 80g/L, sodium carbonate: 180g/L, sodium sulfite: 45g/L, sodium metasilicate: 45g/L, and bamboo is immersed in the bating liquor fully, room temperature was placed 15 days; Or be heated to 90-100 ℃, be incubated 1-5 hour;
Step 3: the bamboo wood after will softening is put into to specify in the service sink and soaked 15 minutes, and flushing is delivered to zone to be processed and dried again, and the bamboo wood that will dry is delivered to the processing of continuous machining district, through heated baking or heated baking not;
Step 4: send into the flattened region after the baking by means of centripetal force, utilize special mould to implement the splitting of bamboo front end lower edge elder generation and flatten gradually again;
Step 5: bamboo is separated through comb after flattening, and fine seperator is driven in employing again becomes the fibre bundle form with bamboo wood;
Step 6: after the air-flow classification, utilize shaker belting and selection by winnowing hierarchy system, remove superbhort fiber and powder, obtain the bamboo fiber bundle of two kinds of different long fineness with the further classification of bamboo bunch fiber;
Step 7: bundle fiber is put into boiling pond pressurized, heated kiering 100 minutes; The kiering 40 minutes of pressurizeing again, temperature is 120 ℃ during kiering, pressure is 3kg/cm2; bath raio is 1:40, contains NaOH: 10g/L, sodium carbonate: 10g/L, sodium sulfite: 2g/L, sodium metasilicate: 1g/L in the kiering liquid
Step 8: with after the kiering bundle fiber in add preservative agent and flame-retardant additive, to increase bundle strength;
Step 9: bamboo fibre is drained, at first clean (bath raio is 1:25, and the time is 3 minutes) to pH value 6-7 then with the dilution heat of sulfuric acid that contains 1.0%; After pickling process finishes, directly in the acid bath pot, inject the mixed liquor Asia of uniform sodium chlorite of dilution and sodium nitrate and float sodium chlorite addition 5g/L; Sodium nitrate 3g/L, bath raio is 1:30, adds sulfuric acid or oxalic acid pH value is transferred to 3; 60 ℃ of temperature, 60 minutes time;
Step 10: bleach through in bath, adding hydrogen peroxide solution, sodium metasilicate, NaOH, soda ash after the above-mentioned processing again; Wherein hydrogen peroxide solution (30%) addition 2g/L, sodium metasilicate addition O.5g/L, addition amount of sodium hydroxide 1g/L, soda ash addition 3g/L; bath raio is 60; pH value is transferred to 10,90 ℃ of temperature, 30 minutes time;
Step 11: the bamboo fibre after will bleaching drains, and at first cleans (bath raio is 1:20, the time: 12 minutes) to pH value 6.5-7 with containing 0.1% dilution heat of sulfuric acid then, cleans the back dehydration with clear water again, last white oil, dries.
Step 12: the health preserving room health was put into 7 days after adding methyl-silicone oil in dehydration back, can prepare fineness at 0.04-0.06 millimeter, the length fine bamboo fiber at the 35-65 millimeter.This bamboo fibre can be used as textile material and uses fiber, replaces cotton, fiber crops etc. to use natural material as industry.Use fiber as non-woven material, composite, replace glass fibre, chemical fibre, jute, flax etc. to use natural material as industry.
The present invention directly processes whole bamboo after flattening through special facility under the situation of hacking without cutting, realized " eat bamboo and tell fiber ", and processing technology does not receive the restriction in bamboo kind, bamboo age, ring, bamboo footpath; Bamboo wood open fine seperator utilization heat one power one change many lotus roots close the bamboo fibre that principle makes processing longer than originally, more carefully, more even, rim charge and unprocessed bamboo material are less; Added additive and made product have good folding resistance and anti-flammability, its production process is reliable, and resource utilization is high, and processing cost is hanged down health, and environmental pollution is little, and constant product quality efficiently solves the high-efficiency large-scale production problem of elongated bamboo fiber.
