It needs.However, so far, there has been no the plant of standard dyes and chemistry dye product discrimination method.Part in the market is caused to plant
It is chaotic that object contaminates product quality, and has the case where part chemistry dye product personation plant dye product.Plant dye is directly affected to produce
The popularization of product and the equity of consumer.
It is found through retrieval, only part individual proposes through the discoloration of color fastness, soda acid and metal ion or color identification
The methods of carry out plant dye and chemistry dye product identification.But the above method largely lacks stringent scientific appraisal, more attaches most importance to
It wants, above method identification result is unobvious, cannot identify to all color or type, does not have versatility.
For the product of same color, plant dyeing is difficult to be distinguished in appearance with chemical staining product；In addition, by
It is different with chemical dye chemical component in the corresponding vegetable colour of different colours, it is distinct, it is also difficult to unification and uses unification
Reagent color developing method is identified.Bleaching can be carried out to dyeing product using conventional bleaching process, according to dyestuff and color
Its different bleaching time are different, therefore can be identified according to bleaching time length to Activities of Some Plants dye and chemistry dye product.But
There are three big technological difficulties for above-mentioned technology: first is that conventional bleaching technique is too long to the bleaching time of dyeing product, it is small to be commonly 1
When, it is difficult to reach the requirement quickly identified；It is bleached second is that conventional bleaching technique cannot contaminate product to the plant of all colours,
Do not have universality for the identification of plant dye and chemistry dye；Third is that plant dye and chemistry of the conventional bleaching technique to certain colors
It is close to contaminate product bleaching speed, that is, there is the phenomenon that the two discoloration simultaneously or bleaching, therefore do not have the ability of identification.
Summary of the invention
Based on above-mentioned technical problem, the present invention proposes that a kind of plant yarn dyeing line and chemical yarn dyeing line bleach quickly identification side
Method, this method have the advantages that quick, easy, accurate and versatile.
The adopted technical solution is that:

Then 3s quickly removes yarn, be placed on white and identify on plate；
Third step identifies
Observation white identifies the color change of yarn on plate in 1-10s after yarn taking-up, if yarn fades or becomes white
Color, then above-mentioned yarn is plant yarn dyeing line；If yarn, without color change, above-mentioned yarn is chemical yarn dyeing line.
Preferably, the inorganic acid is selected from one or more of hydrochloric acid, nitric acid, phosphoric acid and sulfuric acid, the chlorite
Selected from one or more of sodium chlorite, potassium chlorite, barium chlorite, the activator is selected from sodium acetate, ammonium acetate, formic acid
One or more of sodium；The bleeding agent is JFC.
Preferably, the process for preparation of the solution carries out at normal temperature, the adjusting pH value process at 0-100 DEG C into
Row.
The direct bring effect of the above method is that easy to operate, identification is simply, time-consuming is short, result is accurate, and has general
Property, 10s is less than for the identification time of plant dye product.
Likewise, the present invention also provides a kind of plant dye fibers and chemistry to contaminate fiber bleached method for quick identification comprising
Following steps:
The first step, reagent preparation
Choosing chlorite, activator, bleeding agent and inorganic acid is raw material, respectively by chlorite, activator and infiltration
Agent is added in the distilled water of 100mL, so that mass percent concentration is respectively chlorite 1-5%, activator 5-10% and infiltration
Saturating agent 1-5%, preparation obtain solution, and inorganic acid is then added into solution, and adjusting pH value is 1-3, make special agent；
Second step, reagent infiltration
5mL special agent is measured using the empty beaker of 10mL cleaning, fibre bundle is completely immersed in special agent with tweezers
Then 1-3s quickly removes fibre bundle, be placed on white and identify on plate；
Third step identifies
Observation white identifies the color change of fibre bundle on plate in 1-10s after fibre bundle taking-up, if fibre bundle fade or
Become white, then above-mentioned fiber is that plant contaminates fiber；If fibre bundle, without color change, above-mentioned fiber is chemistry dye fiber.
Preferably, the inorganic acid is selected from one or more of hydrochloric acid, nitric acid, phosphoric acid and sulfuric acid, the chlorite
Selected from one or more of sodium chlorite, potassium chlorite, barium chlorite, the activator is selected from sodium acetate, ammonium acetate, formic acid
One or more of sodium；The bleeding agent is JFC.
Preferably, the process for preparation of the solution carries out at normal temperature, the adjusting pH value process at 0-100 DEG C into
Row.
In order to better understand the technical principle of the above method, detailed analysis be described as follows:
To solve the problems, such as that plant dye is difficult to differentiate with chemical yarn dyeing line, fiber, the invention proposes chlorite solutions
Inorganic acid configuration is mixed, above-mentioned configuration is key point of the invention, identifies to final dyestuff and plays extremely crucial effect.
This is because chlorite has blanching effect；But common process uses chlorite and organic acid, above-mentioned configuration
In bleaching process release bleaching effective component chlorine dioxide rate it is lower, bleaching speed is slow, for part color fastness compared with
High product is difficult to achieve the effect that bleaching.The present invention substitutes organic acid using inorganic acid, greatly accelerates effective titanium dioxide
The formation speed of chlorine accelerates the effect of bleaching；Since the dyestuff of plant dyeing is mixture, containing less chromophoric group,
It is easier to be bleached under the action of a large amount of bleaching agents, the more chemical dye of bleaching time is short, and in rapid bleach, the time shortens effect more
It is significant；Therefore solve the problems, such as that bleaching speed is slow, plant dye contaminates that bleaching time is consistent to be difficult to differentiate with chemistry simultaneously.
Even more important, inorganic acid can be eluted or be removed to the dyestuff of yam surface.Since plant dyeing is more chemical
It is low to dye color fastness, most of vegetable colour is stripped under certain density acid processing, also accelerates the drift of plant yarn dyeing line
Bai Sudu.Chemical dye is easy to upper dye since chemical component is pure, and color fastness is high, it is not easy to be removed by acid solution, therefore the short time
Interior no bleaching phenomenon；Therefore it is consistent to solve the problems, such as that Activities of Some Plants dye is difficult to bleach, plant dye with chemistry contaminates bleaching time.
Further, the vigorous reaction that inorganic acid be easy to cause sodium chlorite solution is added, reaction is difficult to control.For control
Reaction speed and direction are added activator sodium acetate, ammonium acetate, sodium formate, control the reaction speed of bleaching, while preventing yarn
Or the destruction of fiber.
Further, bleeding agent is added, accelerates solution in the infiltration of yam surface, shortens contact of the bleaching liquid with dyestuff
Time, more shortening bleaching time, therefore solve the problems, such as that bleaching speed is slow.
It is different from the prior art, above-mentioned technical proposal in chlorite solution by being added inorganic acid, activator and infiltration
Saturating agent can be accelerated the time of contact of reagent and dyestuff, and reaction speed is controlled, and selective elution vegetable colour is simultaneously bleached,
With easy to operate, identification is simple, time-consuming is short, result is accurate, and have the characteristics that versatility, for vegetable colour identification when
Between be less than 10s.
