Description
Technical field
The present invention relates to silk inspection and testing technology, the specially method for quick identification of raw silks of fresh cocoons and dried cocoon raw silk.
Background technology
Fresh silk cocoon is without drying, high temperature cocoon cooking, only after vacuum hot water infiltration is processed, the life that direct filature is made
Silk, referred to as raw silks of fresh cocoons.Conversely, fresh silk cocoon stored by high temperature cocoon drying, certain hour, the raw silk of high temperature cocoon cooking and reel silk from cocoons, then
Referred to as dried cocoon raw silk.Because fresh cocoon reeling operation is less, saves energy consumption and throwing byproduct --- silkworm chrysalis can be made full use of, have
There are certain economic advantages so that fresh cocoon reeling is more prevalent in the raw silk main producing region such as Guangxi.Although the price of raw silks of fresh cocoons is low
In dried cocoon raw silk, but cleanliness and obvolvent index due to raw silks of fresh cocoons are poorer than dried cocoon raw silk, therefore exist between the two
The difference of proterties and performance, especially raw silks of fresh cocoons break end in weaving process, fuzziness, and strand paper splits, fabric dyeing
The probability that dyeing defect occurs in color is higher than dried cocoon raw silk.
In recent years, raw silk industry generally existing reeling enterprises and pretends to be dried cocoon raw silk and silk production to look forward to using raw silks of fresh cocoons
Industry is concluded the business, and seeks the accurate discriminating of the bad phenomenon of high profit, fresh silk and dried cocoon silk to be related to reeling enterprises and silk production
The interests of enterprise and trade disputes therebetween.But because two kinds of raw silk appearance surfaces are identical, protein fibre is complicated, although
The scientific research of current numerous domestic, quality inspection organization propose two kinds of methods of raw silk of several discriminatings, such as pass through scanning electron microscopic observation raw silk
The surface particles characteristic of unknown sample differentiates that fresh silk is (a kind of to check raw silks of fresh cocoons by SEM with dried cocoon silk
Method, application number 201410379015.3)；By the fresh and dried class that raw silk is judged with the whiteness of color measurement instrument test position sample
Type, whitness index average value it is larger be raw silks of fresh cocoons, whitness index average value is less, and for raw silks of fresh cocoons, (colour photometer inspection is fresh
The method of cocoon raw silk)；Compare the raw silks of fresh cocoons of same source and the sericin degumming loss percentage of dried cocoon raw silk or silk gum solution concentration
Size (a kind of method for differentiating raw silks of fresh cocoons and dried cocoon raw silk by silk gum dissolution characteristics, 201510039141.9) uses gel
A kind of length (method for being differentiated raw silks of fresh cocoons and dried cocoon raw silk by sericin gel characteristic, 201510037780.1) of time is come
Distinguish raw silks of fresh cocoons and dried cocoon raw silk, above method exist be only capable of the different fresh and dried performance raw silks of two kinds of same sources of difference which
Individual for dried cocoon, which is fresh cocoon, it is impossible to a kind of fresh and dried performance of unknown raw silk of chance decision, and as dried cocoon Fresh cocoon grading is equal
Its surface cleanliness difference and aberration are smaller when higher, judge that the accuracy of its fresh and dried type is by microscope and whiteness method
It is very low.Therefore there is poor discriminating accuracy, narrow application range, ineffective shortcoming in this several method.
Such as be placed in powder sample on moisture analyser by other two kinds of discrimination methods, in the case where drying temperature is set, during interval
Between record example weight change sequence；The weight change sequence data of the sample to collecting generates datagram, is become according to feature
Change situation completes sample identification (a kind of detection method of raw silks of fresh cocoons, 201510236987.1)；Sample is carried out into efficient liquid phase
Chromatography, so as to obtain efficient liquid phase chromatographic analysis result, the efficient liquid phase chromatographic analysis of testing sample of standard items respectively
As a result；When the efficient liquid phase chromatographic analysis result of testing sample is compared with the efficient liquid phase chromatographic analysis result of standard items, have more
During existing at least one feature group swarming, judge that testing sample is raw silks of fresh cocoons；Conversely, then judging that testing sample is dried cocoon raw silk.
(method of the fresh cocoon reel silk from cocoons raw silk of quick discriminating and dried cocoon reel silk from cocoons raw silk, 201510446043.7).Both approaches are although can be with
Judge a kind of fresh and dried type of unknown sample, but first method needs to set up complicated database, and second method needs
Influence of the accuracy of test stone product, database and standard items to result is very big, and both discrimination methods are excessively complicated,
The operating process of expensive instrument and equipment and complexity is needed, it is relatively costly, and be not suitable with and pushed away in silk production enterprise
Wide application.
Therefore, a kind of simple, efficient, quick, easy-operating fresh cocoon and dried cocoon raw silk discrimination method letter are to be developed.
The content of the invention
The technical problems to be solved by the invention are to provide the method for quick identification of raw silks of fresh cocoons and dried cocoon raw silk, the method
Have the advantages that simple, efficient, quick, easy to operate, accuracy is high, and cost is relatively low, and easily operation, good using adaptability,
Be conducive to being promoted in factory and laboratory inspection work.
The present invention solves above-mentioned technical problem with following technical scheme：
The method for quick identification of raw silks of fresh cocoons of the present invention and dried cocoon raw silk, including following operating procedure：
1) raw silk is pre-processed：At ambient temperature, first by the fresh cocoon of acetone carrying out washing treatment or dried cocoon raw silk fiber
Dimension 2 minutes after take out, then reuse distilled water it is carried out washing 3 times, and be placed under normal atmosphere temperature 18-

2) test fluid is prepared：Neopelex, organic silicon defoamer and distilled water are hybridly prepared into test fluid,
Wherein the concentration of neopelex is 3.5mmol/L, and the mass concentration of organic silicon defoamer is 0.025%, and mixing is equal
It is stand-by after standing 2 hours after even；
3) raw silk test sample is prepared：Several short fibres will be cut into by the fresh cocoon or dried cocoon raw silk fiber of above-mentioned pretreatment
Dimension, every fiber weighs about 0.05mg, is then neatly bundled into 4-12 fibers a branch of, and gross weight is 0.2mg-0.6mg；
4) differential test process：In normal atmosphere, 18-22 DEG C of temperature, the environmental condition that relative humidity is 60-68%
Under, abreast put down gently above-mentioned in the liquid level center of test fluid simultaneously by the raw silk fiber tied up respectively using clean tweezers
Timing is started simultaneously at, fresh cocoon or dried cocoon raw silk natural subsidence to the time of beaker bottom is recorded, if the sedimentation time is less than 300
Second, then raw silks of fresh cocoons is determined that it is, if the sedimentation time is more than 300 seconds, determine that it is dried cocoon raw silk.
The step 2) test fluid regulation pH value be 6.0-7.0, proportion is 1.0.
The inventive method have it is easy to operate, it is with low cost, it is easily accurate the advantages of judge, and cost is relatively low, easily
Operation, it is good using adaptability, it is easy to silk weaving enterprise to select to be suitable for the raw material that the production of this enterprise needs, be conducive in factory and reality
Test and promoted in the inspection work of room.
