Problems solved by technology

[0003] At present, some studies also involve the distinction between fresh cocoon raw silk and dried cocoon raw silk, usually using the fineness to measure and distinguish, but there is no obvious difference in the diameter of fresh cocoon raw silk and dried cocoon raw silk
However, it is still difficult to identify fresh cocoon raw silk and dried cocoon raw silk in the market.

Embodiment 1

[0022] 10 sections of raw silk were randomly cut from fresh cocoon raw silk 1 and dried cocoon raw silk 1, respectively, as test samples, and fixed on transparent glass sheets respectively to ensure that the raw silk was straight but not stretched.

[0023] Calibrate the microscope with a standard plate with a diameter of 70 μm, place the glass slide containing the raw silk sample under the microscope, and adjust the microscope to obtain a clear image of the raw silk.

[0024] Accurately select the width of any raw silk on the raw silk image with smooth and flat edges, use the length reading function of the microscope to read the diameter of fresh cocoon raw silk 1 as 56.464268μm, record the data, and take a test image, repeat the process Step Measure the diameter of the remaining raw silk samples.

Abstract

The invention discloses a method for identifying fresh cocoon raw silk and dried cocoon raw silk through diameter size of raw silk. The method comprises the following steps: arbitrarily intercepting two types of raw silk from the same source as raw silk samples, fixing on a transparent glass sheet, calibrating a microscope by using a standard board, placing the glass sheet carried with the raw silk samples below the microscope, to obtain a clear raw silk image, selecting the width of the raw silk at any position of the image, reading to obtain the numerical value of the raw silk diameter by using the microscope, counting the diameters of two types of the raw silk, calculating the average diameter of two types of the raw silk, and comparing the size of the average diameter to identify the fresh cocoon raw silk and the dried cocoon raw silk. The method has the characteristics of simpliness and easiness, convenience and rapidness, and cheap cost, and is good for identifying the fresh cocoon raw silk and the dried cocoon raw silk by a silk weaving enterprise, so that the raw material needed by the enterprise production can be selected suitably.

Description

technical field [0001] The invention relates to a method for identifying raw silk, in particular to a method for identifying fresh cocoon raw silk and dried cocoon raw silk according to the diameter of the raw silk, so as to distinguish the fresh cocoon raw silk and the dried cocoon raw silk. Background technique [0002] Fresh cocoon raw silk is raw silk made from fresh cocoon, which is directly reeled after vacuum hot water infiltration treatment. Compared with the traditional silk reeling technology, fresh cocoon silk reeling saves the cocoon drying and cocoon cooking steps, reduces energy consumption and saves costs; and fresh cocoon silk reeling by-product fresh pupa has higher utilization value, which can improve production enterprises economic benefits. The fresh cocoon reeling technology saves the cocoon drying step, reduces the influence of temperature on cocoon silk quality, and helps to retain the natural characteristics of silk. However, due to the difference i...
