MANUFACTURING TESTS OF COTTON 29 
The different grades of cotton were spun into 22s warp yarn satis- 
factorily. A considerable quantity of dust and fly was given off 
when running grades 7, 8, and 9. 
The finishing properties of the lower grades for bleaching and 
dyeing were not so satisfactory as those of the higher grades. The 
lower grades produced less bright yarns than did the higher grades. 
Brightness of the lower grades may be obtained by bleaching, but 
this is usually done at a sacrifice of strength. 
The strength of the finished 22s warp yarns and the 28s two-ply 
soft twisted yarns followed generally the strength of the gray yarns. 
The effect of the finishing was practically the same for eastern and 
western yarns. 
The strength of the gray cloth followed closely the strength of the 
gray yarns. 
The strength and regularity of the finished yarns and cloth varied 
with the finishing plants and the methods used.
