Embodiment 1

[0022] The detection method of raw silk whiteness in the present embodiment comprises the following steps:

[0023] (1) Connect the spectrophotometer and the computer, turn on the switch of the colorimeter, and set the standard light source. Open the color quality control system, perform zero and white calibration, and create a file for storing data;

[0024] (2) Take No. 1 raw silk sample, wrap the raw silk densely and evenly on a 1.5cm wide cardboard, and ensure that it has a plane of 1cm×1cm, and use it as a raw silk sample;

[0025] (3) Place the prepared raw silk sample flat on the sample measuring place of the spectrophotometer, open the measurement window, click the "average start" button, and measure the whiteness index of this side of the raw silk sample;

[0026] (4) Turn the raw silk sample back, measure the whiteness of the other side of the raw silk sample according to step (3), and obtain the whiteness index of the other side of the raw silk sample. Click the "...

Embodiment 2

[0035] The detection method of raw silk whiteness in the present embodiment comprises the following steps:

[0036] (1) Connect the spectrophotometer and the computer, turn on the switch of the colorimeter, and set the standard light source. Open the color quality control system, perform zero and white calibration, and create a file for storing data;

[0037] (2) Take No. 3 raw silk sample, wrap the raw silk densely and evenly on a 1.5cm wide cardboard to ensure that it has a 1cm×1cm plane, and use it as a raw silk sample;

[0038] (3) Place the prepared raw silk sample flat on the sample measuring place of the spectrophotometer, open the measurement window, click the "average start" button, and measure the whiteness index of this side of the raw silk sample;

[0039] (4) Turn the raw silk sample on its reverse side, measure the whiteness of the other side of the raw silk sample according to step (3), and obtain the whiteness index of the other side of the raw silk sample. C...

Embodiment 3

[0048] The detection method of raw silk whiteness in the present embodiment comprises the following steps:

[0049] (1) Connect the spectrophotometer and the computer, turn on the switch of the colorimeter, and set the standard light source. Open the color quality control system, perform zero and white calibration, and create a file for storing data;

[0050] (2) Take No. 5 raw silk sample, wrap the raw silk densely and evenly on a 1.5cm wide cardboard, and ensure that it has a plane of 1cm×1cm, and use it as a raw silk sample;

[0051] (3) Place the prepared raw silk sample flat on the sample measuring place of the spectrophotometer, open the measurement window, click the "average start" button, and measure the whiteness index of this side of the raw silk sample;

[0052] (4) Turn the raw silk sample back, measure the whiteness of the other side of the raw silk sample according to step (3), and obtain the whiteness index of the other side of the raw silk sample. Click the "...

Abstract

The invention relates to a method for detecting the whiteness of raw silks, and in particular relates to a method for judging the types of raw silks of fresh cocoons and raw silks of dried cocoons, and identifying the type differences of raw silks. The invention discloses a method for detecting raw silks of fresh cocoons by using a color photometer, which comprises the following specific steps: connecting a spectro-color photometer with a computer, starting a switch of the color photometer, setting a standard light source, opening a color quality control system, carrying out zero correction and whiteboard correction, and establishing data storage files and the like. According to the invention, by using the characteristics of color difference among different raw silks, the exponential value of whiteness is measured by using a spectro-color photometer, and according to a rule that the exponential value of whiteness of raw silks of fresh cocoons is greater than the exponential value of whiteness of raw silks of dried cocoons, the dried and fresh types of raw silks are judged. The method disclosed by the invention has the advantages that the method is rapid, accurate and convenient and the like, facilitates the accurate grasping of quality of raw silks, and ensures the quality of products and the production efficiency of silk articles.

Description

technical field [0001] The invention relates to a method for detecting the whiteness of raw silk, in particular to a method for judging the types of raw silk from fresh cocoons and raw silk from dried cocoons, and identifying the difference in types of raw silk. [0002] Background technique [0003] With the advancement of science and technology, the silk industry has developed rapidly, the silk-making process has become more scientific, and the quality of raw silk has been steadily improved. In order to reduce production costs and simplify the operation process, some enterprises try to store fresh silkworm cocoons directly in cold storage without drying them. The silk reeling process does not go through the cocoon cooking process anymore, but directly uses frozen fresh cocoons (or directly uses fresh cocoons that have not been frozen) to be reeled into raw silk by vacuum infiltration and low temperature (the raw silk reeled by this method becomes fresh cocoon and raw sil...
