﻿COMPARATIVE SPINNING TESTS OF COTTCTN. 5 



The different varieties arranged in the order of their strength 

 values, after allowing for the difference in the length of staple of the 

 cotton, are as follows (strongest at top of list) :

 IRREGULARITY OF YARNS. 



The irregularity of the yarn was determined by calculating the 

 average deviation of the sizings and breaking strengths per skein of 

 120 yards. 



Table 6 gives the percentages of average deviation in the sizings 

 per skein of 120 yards.

Table 6 shows that the yarns made from the different varieties of 

 cotton were practically equal in evenness.

MANUFACTURING PROPERTIES, 



No difficulty was encountered in running any of the varieties, all 

 showed excellent spinning qualities.
