Abstract
The invention relates to a bamboo fiber, and in particular relates to a raw bamboo fiber material for a shirt, which is directly produced by raw bamboos. The bamboo fiber material is prepared by the following steps of: sorting, flattening, softening, splitting, boiling, pickling, carrying out bamboo vinegar treatment, carrying out soaking flame retardant treatment, and carrying out microwave vacuum drying. The softening adopts microwave softening: the flattened bamboo is soaked in softening liquid, and then the bamboo soaked with the softening liquid is conveyed into a microwave vacuum tank for carrying out microwave softening treatment; the bamboo vinegar treatment includes primary bamboo vinegar treatment and secondary bamboo vinegar treatment; and the soaking flame retardant treatment adopts vacuum pressurization flame retardant treatment: in a treatment process, the bamboo filament fiber subjected to bamboo vinegar treatment is firstly put into a vacuum pressurization tank for vacuumizing to enable the vacuum degree of the bamboo filament fiber to be (-0.015)-(-0.025)Mpa, then a flame retardant is added into the tank, and the pressure in the tank is increased to 0.1-0.8Mpa. The bamboo fiber provided by the invention has a flame retardant effect, has good air permeability, is smooth and is especially suitable for shirts.
Description
Technical field
The present invention relates to a kind of bamboo fibre, relate in particular to the former bamboo of a kind of usefulness and directly produce the bamboo fiber material that is used for shirt.
Background technology
Bamboo fibre in the market has following two classes: the one, and the regenerated fiber with bamboo pulp is produced is commonly referred to bamboo pulp fiber; The 2nd, the fiber through special process directly extracts from bamboo is called bamboo fiber.Because bamboo fiber has more superior performance at aspects such as hygroscopicity, gas permeability, spinnabilitys, therefore studying the spinnability bamboo fiber has obvious economic benefit and good social benefit.
China foretells existing many patents of invention in the bamboo fiber manufacture method in recent years, CN11078520C has announced a kind of manufacture method, CN1261290C that former bamboo is opened bar, kicker, formation bamboo fiber bundle goods and has announced a kind of method that former bamboo bamboo chip is adopted pure physics, by the boiling sub-wire, desaccharification, degrease, after protein, starch are processed, through mechanical impact, tear, shredding becomes bamboo fibre.CN1185086C has announced by cold rolling, poach and has soaked, dewaters and comb the operations such as fiber processed, and the fiber of acquisition is mainly for the production of bamboo fiberboard.CN1217038 has announced a kind of preparation method of bamboo fiber from bamboo, and this preparation method prepares, softens, washes, rolls, washes, urinates oxygen processing, washing, alkali lye kiering, washing, the processing of urine oxygen bamboo vinegar, pickling, the step order such as dewaters, shakes up, dries and can make bamboo fibre by sample.
Yet the said method production stage is loaded down with trivial details, and the processing time is long, and the fineness of bamboo fiber products and pliability are still waiting to improve, and these bamboo fiber products do not have flame retardant effect.
Summary of the invention
The purpose of this invention is to provide a kind of have flame retardant effect, good permeability, smooth, especially be suitable for the bamboo fiber material of shirt.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
Be used for the bamboo fiber material of shirt, it may further comprise the steps successively: select materials, flatten, and softening, open fibre, boiling, pickling, bamboo vinegar is processed, dipping flame treatment, micro-wave vacuum;
Described softening employing microwave softened, bamboo wood after flattening is immersed in the bating liquor, the bamboo wood that then will be soaked with bating liquor is sent in the microwave vacuum tank, be evacuated to vacuum for-0.02MPa～-0.001MPa, carrying out microwave softened processes again, microwave frequency is 300MHz～950MHz, and microwave treatment time is 1～3min;
Described bamboo vinegar is processed and is comprised a bamboo vinegar processing and the processing of secondary bamboo vinegar, it is that bamboo fibre is immersed in 20-40min in 40-50 ℃ the bamboo vinegar treatment fluid that bamboo vinegar is processed, it is that bamboo fibre is immersed in 10-30min in 55-80 ℃ the secondary bamboo vinegar treatment fluid that the secondary bamboo vinegar is processed, the bamboo vinegar aqueous solution that a described bamboo vinegar treatment fluid is 20-30g/L, the mixed solution that the bamboo vinegar that described secondary bamboo vinegar treatment fluid is weight ratio 1:0.1-0.2:60-100, chelating agent and water form;
Described dipping flame treatment adopts the vacuum pressed flame treatment, bamboo filamentary fibers after first bamboo vinegar being processed in the processing procedure pack into the vacuum pressed tank vacuumize make its vacuum for-0.015MPa～-0.025Mpa, then fire retardant is added in the tank and pressure is added to 0.1MPa～0.8Mpa; Described fire retardant is counted composed of the following components by weight: 20～50 parts of ammonium low polyphosphates, 10～25 parts in ammonium phosphate, 6～12 parts of ammonium pyrophosphates, 5～20 parts in ammonium sulfate, 5～10 parts of boric acid, 10～25 parts in water.

The contrast of table 1 fibre property
Explanation of tables:
1. oxygen index (OI) (OI) refers under defined terms, and material carries out the required minimum oxygen concentration of flaming combustion in oxygen-nitrogen mixture stream.Numerical value with the shared percentage by volume of oxygen represents.The high expression of oxygen index (OI) material is nonflammable, and the low expression of oxygen index (OI) material burns easily, it is generally acknowledged that oxygen index (OI)＜22 belong to combustible material, and oxygen index (OI) belongs to combustible material, oxygen index (OI) between 22-27〉27 genus nonflammable materials.
Hand feel evaluation in two steps, the first step is evaluation feel style, comprises flexibility, fluffy, smooth, elasticity, the performance such as active; Second step is rating, and the feel grading is divided into 5 grades, and 1 grade the poorest, and 5 grades best, and evaluation result is averaged.
3. the testing standard of bacteriostasis rate and antibacterial value is JISL1902-2008.
As can be seen from Table 1:
(1) oxygen index (OI) of embodiment of the invention gained bamboo fiber products is high, and flame retardant effect is better than existing flame retardant products and comparative example's product;
