Embodiment 1

[0019] The method for detecting silkworm cocoon shrinkage and wrinkle in this embodiment includes the following steps.

[0020] (1) Take cocoon A as the cocoon to be tested, take a cocoon A sample, use the roughness detector to detect the cocoon A sample, put the sensor pin of the roughness detector on the surface of the cocoon A sample, start The switch of the roughness detector makes the sensor stylus slide along the surface of the silkworm cocoon A sample at a constant speed. The sliding speed is 0.135mm / s, and the sliding time is 1.85 seconds. After the sliding is over, the roughness detector displays 1 a roughness value.

[0021] (2) Change the surface position of the cocoon A sample in step (1), repeat step (1) to measure the roughness of the cocoon A sample, and obtain another roughness value.

[0022] (3) Step (2) was repeated 8 times to obtain 8 roughness values ​​of cocoon A sample. From steps (1), (2) and (3), it can be seen that the cocoon A was tested 10 times, ...

Abstract

The invention relates to a detection method for silkworm cocoon corrugating. A method which is simple and rapid in operating and used for detecting the corrugating degree of a silkworm cocoon does not exist at present. The detection method for silkworm cocoon corrugating includes the following steps: (1) taking a silkworm cocoon sample, enabling a sensor contact needle of a roughness detector to slide along the surface of the silkworm cocoon sample, the sliding speed is 0.135 millimeters per second, the sliding time is 1.85 seconds, and a roughness numerical value is obtained; (2) changing the surface position of the silkworm cocoon sample, repeating step (1) and obtaining another roughness numerical value; (3) repeating the step (2) 8 times and obtaining 8 roughness numerical values; (4) conducing roughness detection on another 9 silkworm cocoon samples according to the step (1), the step (2) and the step (3); (5) counting the general average of the roughness of the silkworm cocoons according to the roughness numerical values gained in the step (1), the step (2), the step (3) and the step (4); (6) judging the good and bad of the corrugating degree of the silkworm cocoons according to the general average of the roughness, the bigger the value is , the thicker the corrugating is, and the smaller the value is ,the thinner the corrugating is. The detection method for the silkworm cocoon corrugating is simple and rapid in operating.

Description

technical field [0001] The invention relates to a silkworm cocoon shrinkage detection method, which is used for detecting the silkworm cocoon shrinkage degree, and belongs to a method for detecting silkworm cocoon quality. Background technique [0002] Cocoon shrinkage refers to the tiny raised wrinkles on the surface of the cocoon layer. Cocoon shrinkage is caused by the difference in drying speed of cocoon silk inside and outside the cocoon layer. In this process, the outer layer of cocoon silk is dried before the inner layer of cocoon silk. In addition, during the natural drying process of the cocoon layer, the outer layer of cocoon silk is dried first, and the inner layer of cocoon silk is dried later. Because the cocoon silk will shrink when it is dry, when the inner layer of cocoon silk is gradually dried, it will pull the outer layer of dry cocoon silk and shrink at the same time, thus forming shrinkage. [0003] There are many factors that affect the cocoon shrinkag...
