Embodiment 1

[0017] Preparation of bamboo charcoal ultrafine powder (particle size ≤ 0.5 μm) product.

[0018] 1. First, coarsely grind the commercially available bamboo charcoal to a particle size of about 50 μm (ie 300 mesh), and then ultrafinely grind it to a particle size of about 2.6 μm (about 5000 mesh). As a raw material for further ultra-fine processing.

[0019] 2. Put 100 grams of the above-mentioned bamboo charcoal with a particle size of 2.6 μm in a ball mill, add 0.5 grams of dispersant, and 400 milliliters of deionized water, and use a ball made of alumina or corundum (the ball diameter is 0.5 to 3 mm) Ball mill for 80 hours to obtain bamboo charcoal slurry material, take it out and place it in a high-speed centrifugal sedimentation classifier for classification treatment, wherein the components that meet the standard (that is, the slurry with a particle size ≤ 0.5 μm) are concentrated in the middle of the classifier, and drawn out Finally, it is stored in the storage tank, ...

Embodiment 2

[0023] Add bamboo charcoal ultrafine powder (particle size ≤ 0.5 μm) to synthetic fiber raw materials to prepare "bamboo charcoal masterbatch".

[0024] The bamboo charcoal superfine powder of embodiment 1 gained is added in the synthetic fiber chip of 2kg, and the addition of bamboo charcoal can be selected in the scope of 10~35% (wt), and said chip is a kind of in polyester fiber, polypropylene fiber , placed in a small laboratory kneader at 160°C for half an hour, then placed in a screw extruder, extruded and granulated at 260°C to prepare fiber masterbatches containing bamboo charcoal, referred to as " "Bamboo charcoal masterbatch" can be supplied to the market as a product.

Embodiment 3

[0026] Preparation of various specifications of "bamboo charcoal fiber".

[0027] The "bamboo charcoal masterbatch" obtained in Example 2 is mixed with synthetic fiber chips (such as polyester, polypropylene fiber, etc.) in a certain ratio and dried, wherein the "certain ratio" refers to the total weight of synthetic fiber raw materials, bamboo charcoal The content should be selected within the range of 0.5-3.0% (wt), and then the fiber products of various specifications can be prepared in the drawing section of the chemical fiber factory according to the conventional process, such as can be processed into fine denier (≤1.0-1.5 denier), medium denier (1.5 Denier or above), three-dimensional mesoporous fiber, five-hole, seven-hole fiber and other products are used as processing raw materials for the apparel industry and supplied to the market.

Abstract

A process for preparing the superfine (less than 0.5 microns) particles of charred bamboo and the application of said superfine particles in preparing the synthetic fibres are disclosed. Said synthetic fibres features high insulating function, antibacterial action, and adsorptivity, and radiating far infrared rays.

Description

technical field [0001] The invention belongs to a raw material ultra-fine processing and classification technology, in particular to a method for mechanical ultra-fine crushing and grading treatment of bamboo charcoal, and the application of ultra-fine bamboo charcoal powder to synthetic fiber raw materials to process bamboo charcoal masterbatch or A method of processing fiber filaments of various specifications. Background technique [0002] Bamboo charcoal is an important product direction in the development of the bamboo industry in many provinces in southern my country. Bamboo charcoal is made by using the local abundant bamboo forest resources for reasonable and effective development and utilization, and is roasted at high temperature. Bamboo charcoal is a porous object with a surface area of ​​up to 700m 2 / g, which is twice that of charcoal, has excellent adsorption and separation, moisture absorption and drying, deodorization and antibacterial properties, and can be...
