Description
Technical field
The present invention relates to a kind of detection method of raw silk whiteness, specifically, being a kind of for judging fresh cocoon raw silk and dried cocoon raw silk type, differentiating the method for raw silk type difference.
Background technology
Along with the progress of science and technology, silk reeling industry obtains fast development, and technology for making tobacco threds is more scientific, and raw silk quality obtains and stably improves.In order to reduce production cost, simplify the operation flow process, and some enterprises attempt by fresh silk cocoon without dry storage, but be directly transported into freezer quick-frozen storage.Filature adds man-hour also no longer through cocoon cooking operation, but directly freezing fresh silk cocoon (or directly adopting the fresh cocoon without freezing processing) is adopted vacuum infiltration, low temperature reel silk from cocoons raw silk (raw silk adopting reel silk from cocoons in this way becomes fresh cocoon raw silk).Fresh cocoon raw silk is less by high-temperature heat treatment in process, and its silk performance and dried cocoon raw silk (raw silk of the dry silk cocoon reel silk from cocoons after super-dry is processed) have different, makes silk weaving processing enterprise select raw silk raw material to bring puzzlement.At present, market also there is no the method differentiating fresh cocoon raw silk and dried cocoon raw silk fast and easily.
Because of the difference of processing technology, there is certain color distinction in fresh cocoon raw silk and dried cocoon raw silk.Because raw silk color distortion is less, cannot be judged by naked eyes.The present invention adopts colour photometer to carry out detection to raw silk whiteness and analyzes, and differentiates fresh cocoon raw silk and dried cocoon raw silk type, has the effect of accuracy of judgement.
Summary of the invention
The object of the present invention is to provide a kind of swift to operate, method that result detects raw silk whiteness accurately, for differentiating fresh cocoon raw silk and dried cocoon raw silk.
A kind of colour photometer of examining checks the concrete steps of the detection method of the method for fresh cocoon raw silk as follows:
(1) connect spectrophotometric color measurement instrument and computer, start colour photometer switch, standard sources is set, opens color quality control system, carry out zero-bit, blank corrects, set up the file of stored data;
(2) get a kind of unknown raw silk sample, raw silk is fine and close, smooth being wrapped in above the wide hard paper of 1.5cm, ensures that it has 1cm × 1cm plane, as raw silk sample;
(3) the raw silk sample prepared is lain in the test sample place of spectrophotometric color measurement instrument, open measurement window, click " on average starting " button, measure the whitness index obtaining this one side of raw silk sample;
(4) raw silk sample is carried out reverse side, measure the whiteness of raw silk sample another side according to step (3), obtain the whitness index of this raw silk sample another side, click " on average terminating " button, storage, obtain the 1st whitness index value of raw silk sample;
(5) from raw silk sample, again get silk according to step (2), produce another raw silk sample;
(6) measure, obtain the 2nd whitness index value of raw silk sample according to step (3), (4);
(7) according to step (5), (6) duplicate measurements 6 times again, other 6 whitness index values of raw silk sample are obtained;
(8) 8 whitness index values above-mentioned steps obtained are averaged to count and calculate, and obtain the whitness index mean value of this raw silk sample;
(9) according to step (2) ~ (8), the whitness index mean value of another unknown raw silk sample is detected;
(10) according to the size of whitness index mean value, differentiate raw silk difference, judge the fresh and dried type of raw silk; What whitness index mean value was larger is fresh cocoon raw silk, and what whitness index mean value was less is fresh cocoon raw silk.
The present invention has the following advantages and effect: the present invention utilizes the feature that there is color distortion between different raw silk, adopts spectrophotometric color measurement instrument to record whitness index value, is greater than the rule of dried cocoon raw silk, judges the fresh and dried type of raw silk according to fresh cocoon raw silk whitness index.The advantages such as the present invention has fast, accurate, convenient, are conducive to accurate assurance raw silk quality, ensure product quality and silk fabrics productivity effect.
