﻿SPINttlNfJ TESTS of COTTON. 



15 



Plate V, Figiire 1, is from a photograph of 40 's yarn spun from the 

 Delta 1^-inch cotton which shows practically no difference in the 

 quality of the yarn spun from the different types of hales. 



MANUFACTURING PROPERTIES. 



There was no noticeable difference in the running of the different 

 types of bales. 



SUMMARY OF TESTS. 



The results of this test show that compressing cotton does not 

 injure its spinning value. 



SPINNING TESTS OF WEBBER 49 COTTON OF 1\ INCH STAPLE. 



The Webber 49 cotton was compressed into four bales: A flat bale, 

 a standard or railroad compressed bale, a high-density bale, and a 

 high-density bale compressed in a wet condition. The latter bale 

 was made by wetting a flat bale with water from a hose for a day 

 and then compressing it to high density in the usual manner. 



PERCENTAGE OF WASTE. 



Table 13 gives the percentage of visible, invisible, and total waste 

 obtained from the different types of bales.
