Description
Technical field
The invention belongs to the textile industry field, specifically a kind of method of textile fibres industry supply chain supervision checking.
Background technology
Low-carbon economy, environmental protection, green product, social responsibility and sustainable development all are the important issue of the world today; The focus of future enterprise competitive power especially; This has also impelled the fast development in recent years of tencel industry; The regeneration that makes full use of the natural resources is processed, and develops a circular economy, and has also become the trend of the times of current weaving industrial community.Cyclic regeneration and new function textile product have become many enterprises and have pursued social responsibility, the key of winning victory of winning the market and trusting with the consumer.
But; Because great majority regeneration and tencel goods are difficult to rely on merely detection means effectively to differentiate the source of its fiber; Along with the fiber and the goods thereof of increasing " oneself declares " come into the market; Problems such as very different in supply chain link parts such as fibrous raw material, semi-manufacture, finished product production and sale thereof, shortage is restrained oneself, and disorderly competition, the raw material that many markets occurred mingled, the imitative phenomenon of product is serious.How realizing regenerating and the effective monitoring of tencel supply chain, prove the fiber source of product, not only directly influence brand and consumer's interests, also is the common challenge that each link manufacturer, retailer, trader are faced in the supply chain.
Press for the method for effective monitoring of a kind of ability and witness fiber source.
Summary of the invention
Technical matters to be solved by this invention provides the method for effective monitoring of a kind of ability and witness fiber source.
Technical matters to be solved by this invention can be able to solve through following technical scheme:
A kind of method of textile fibres industry supply chain supervision checking is characterized in that, comprises the steps:
(1) allotment of textile fibres tracer agent
Fiber tracer agent after the dilution is joined in the metal ion masking agent after the dilution, again with the pH value of sodium hydroxide solution adjustment solution to 7.0-7.5, tracer concentration is 0.2～20g/kg;
(2) according to fiber spinning process, the tracer agent solution after the allotment is added in the spinning solution, the content of tracer agent is 20～2000mg/kg in the fibrous finished product;
(3) textile fibres production and supply chain supervision checking,
Through rigorous, science and standardized procedure, overall processes such as fibrous raw material, production technology, equipment, fibrous finished product are supervised;
(4) through detection, fiber is discerned checking to tracer agent in the weaving finished product.
Wherein said fiber tracer agent is selected from slaine or metal oxide.
Said metal is selected from yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, bismuth, polonium.
Said slaine comprises nitrate, chlorate, sulfate, carbonate etc.
Said metal ion masking agent is that ability and tracer agent ion generation chelation form stable water soluble complex, is selected from aminocarboxylic acids, hydroxycarboxylic acid, polycarboxylic acid, pentanedione class, polyacrylate etc.
Said detection to tracer agent in the weaving finished product adopts inductive coupling plasma emission spectrograph (ICP-OES) to carry out.
The detection of said tracer agent is according to carrying out as follows: finished product is cleared up in the micro-wave digestion jar with strong acid such as sulfuric acid, nitric acid, hydrochloric acid, extract is filtered in high temperature 160-200 ℃ of following boiling, and ICP-OES 160-800nm wavelength covers continuously.
Said finished product includes but are not limited to fiber, yarn, lining, clothes, household textiles.
Beneficial effect of the present invention: the application technology that adopts high-tech fiber tracer agent; Fiber supply chain production run is supervised witness; And adopt inductive coupling plasma emission spectrograph to detect tracer content in the textile product, thereby play the effect of employed fiber in the weaving finished product being differentiated checking.Adopt the inventive method can realize true reflection, safeguard brand names, prevent fake and forged commodity, protection consumer's interests textile raw material.
Embodiment
The present invention will be described below in conjunction with specific embodiment, but the scope of the invention is not limited to this.
Embodiment 1
1, the allotment of textile fibres tracer agent
In having the agitated reactor of stirring apparatus, add 22.48 parts of tracer agents (the part here is in mass, and is as follows) and 477.52 parts of water, be heated to 95 degrees centigrade, be stirred to clear, whole solution is 500 parts.
In having the agitated reactor of stirring apparatus, add 221 parts of metal ion masking agents earlier, add 279 parts deionized water then, agitator makes whole solution stirring even.500 parts of whole solution weight.
The tracer agent solution for preparing is slowly joined metal ion masking agent solution, and whole process control needed to guarantee the abundant stirring of screening agent solution at 1-2 hour in this process, avoid the local ion excessive concentration, produced the sediment that is difficult to dissolve again.
In adition process, can see in the solution white floccus occurring, under continuous mechanical agitation, white floccus can fade away in solution.
10% sodium hydroxide solution with 22 parts slowly joins in the above-mentioned solution, and it is neutral making solution, and this moment, the pH value was 7.0-7.5.
2,, add the tracer agent solution after allocating according to fiber spinning process
According to spinning technique, before fiber spray silk, evenly join the tracer agent solution dilution after the allotment in the fiber liquid for 12 times, the throughput ratio of tracer agent solution and fiber liquid is 2.4%, through spinning, aftertreatment, last tracer agent stably enters into fibrous finished product.
3, textile fibres supply chain production run supervision witness (suggestion deletion)
, science rigorous through a whole set of and standardized procedure, to the supervision of overall processes such as fibrous raw material, production technology, equipment, fibrous finished product, the raw material sources of actual response fiber satisfy environmental protection, ecology, functional and resource reutilization product demand.
4, adopt inductive coupling plasma emission spectrograph (ICP-OES) tracer agent to detect, fiber is discerned evaluation
The textile fibres tracer agent is more stable in fiber, after weaving, is difficult for loss in the road processing, through the detection to the tracer content in the final finished, detects and is limited to 5mg/kg, discerns and identify the fiber type in the finished product.
From fibrous finished product, whenever got an appearance at a distance from 15 minutes, get 5 samples altogether.
During test, get the 0.25g sample, shred, put into the micro-wave digestion jar; Add 10ml nitric acid, 2ml hydrochloric acid, 160-200 ℃ of following boiling 20 minutes; Filter extract, add deionized water to certain amount; Test with ICP-OES.
Test result is following:
| Sample number into spectrum | Tracer test result (mg/kg) |
| P05-01 | 82 |
| P05-02 | 80 |
| P05-03 | 86 |
| P05-04 | 83 |
| P05-05 | 84 |
Can find out that from above test result the content of tracer agent and original addition 80～85mg/kg meet basically in the finished product, explain that the inventive method can be used for fibrous raw material is monitored.
Can find out from embodiment 1; Add quantitative tracer agent through before spinning, adding in spinning solution or section; And then each link of road, back is measured the tracer content in the finished product; Can verify raw materials used spinning solution that has added quantitative tracer agent or the fiber of cutting into slices preparation of whether serving as reasons of this finished product effectively, the source of guaranteeing fibrous raw material.
