Embodiment Construction
[0032] The present invention will be further described in detail below with reference to the examples, but the embodiments of the present invention are not limited thereto.
[0033] A kind of production method of bamboo fibril, it comprises the steps:
[0034] S1: Cut materials, cut bamboo into bamboo pieces with a length of 7-30cm and a width of 5-10cm.
[0035] The invention adopts the short film process to cut bamboo into short bamboo pieces with a length of 7-30 cm, which is convenient for transportation and processing, and realizes continuous, mechanized and automated operations; closed and softened, the bamboo pieces are softened in a closed pressure reactor, which can Increase the softening temperature to above 100°C, shorten the softening time by two-thirds, and reduce the dosage of medicines by 50%.
[0036] S2: Screening, first use a sieve with an aperture of 4-6 cm to process the bamboo chips cut in step S1 to remove fine bamboo chips and bamboo chips; then use a s...

Abstract
The invention discloses a method for producing natural bamboo fibers, which comprises the following steps of: cutting: cutting bamboos into bamboo chips with the length of 7-30cm and the width of 5-10cm; s2, screening is conducted, specifically, the bamboo chips cut in the step S1 are treated through a sieve with the aperture being 4-6 cm, fine bamboo chips and bamboo scraps are removed, and too large bamboo chips are removed through a sieve with the aperture being 6.4-6.6 cm; washing, wherein the bamboo chips screened in the step S2 are washed with water; softening is conducted, specifically, a solution containing, by mass, 12%-18% of ammonium sulfite, 0%-7% of ammonia water, 0%-5% of urea and 3%-5% of caustic soda is used for softening the washed bamboo chips; cleaning, wherein the softened bamboo chips are washed with water until the pH value is 7.5 or below; opening is conducted, specifically, the cleaned bamboo chips are extruded through a mechanical method, so that the structures of the bamboo chips are loose, and bamboo filaments are dispersed; and then separating and drying. The natural bamboo fibers produced by the method are consistent in length and thickness, soft in texture, low in dust content and low in production cost.
Description
technical field [0001] The invention relates to the technical field of bamboo fiber production, in particular to a production method of bamboo fibrils. Background technique [0002] Bamboo fibrils are cellulose fibers extracted from naturally grown bamboo. Bamboo fibrils have the characteristics of good air permeability, instantaneous water absorption, moisture conductivity, strong abrasion resistance and good dyeing properties, and have natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions. The chemical components of bamboo fibrils are mainly cellulose, hemicellulose and lignin, all of which belong to natural macromolecular polymers, and the total amount accounts for more than 90% of the dry mass of the fiber, followed by protein, fat, tannin, pigment and ash. etc., most are present in the cell wall. Cellulose is the main substance that composes bamboo fibrils, and it is also the significance of it as a textile fiber. [0003] In th...
