for the capacitive method, the defect whose length is equal to or greater than 1 mm and whose mass surpasses 80 % of the average mass of the testing sample; for the optical method, the defect whose length is equal to or greater than 1 mm and whose cross-sectional area surpasses 80 % of the average cross-sectional area of the testing sample
Note 1 to entry: Slub can be classified into big slub and small slub, which can be referred to A.11.
for the capacitive method, the defect whose length is equal to or greater than 10 mm and whose mass surpasses 35 % to 80 % of the average mass of the testing sample; for the optical method, the defect whose length is equal to or greater than 10 mm and whose cross-sectional area surpasses 30 % to 80 % of the average cross-sectional area of the testing sample
for the capacitive method, the defect whose length is equal to or higher than 10 mm and whose mass is over 40 % lower than the average mass of the testing sample; for the optical method, the defect whose length is equal to or higher than 10 mm and whose cross-sectional area is over 30 % lower than the average cross-sectional area of the testing sample defect whose length is no greater than 1 mm, and whose mass or cross-sectional area surpasses 80 % of the average mass or the average cross-sectional area of the testing sample
Defects of raw silk, soaked or unsoaked, are evaluated, clasified, and counted on the basis of variation of the electric capacity, in case of capacitive sensors, and of the photoelectric effect, in case of optical sensors, when passing through suitable sensors splits. The difference between optical and capacitive sensors in detecting defects of raw silk is shown in Annex B.
The evenness of raw silk, soaked or unsoaked, is evaluated and counted on the basis of variation of electric capacity only in capacitive sensors.
The measurements are performed on individual yarn.BS ISO 15625 pdf download.
