The analysis of the influence of sample grams of scoured sheep wool on length of hand row
Hand length is the most commonly used and intuitive method to measure the length of washed sheep wool,but the experience and technology requirements of its inspectors are high.80mg washed sheep wool is difficult to complete the arrangement in the actual operation.After reducing the sampling grams of manual arrangement length,the length value of the data was analyzed,and the samples with the weight of 80 mg,70 mg,60 mg,50 mg were selected to carry out the manual arrangement length test,and the artificial error was avoided in the process of the test.The results showed that there was no significant difference in the length of handrail between 70 mg and 60 mg weight.It was suggested that the sampling grams of washed sheep wool should be changed to 60 mg～80 mg.
