328 THE WOOL CROP 



Carbonized Wool. That which has been treated with a solution 

 of aluminum chlorid or sulfuric acid to remove vegetable matter. 

 Carbonizing is rarely practiced with worsted wools. 



Carding. Consists of opening the wool staples, separating to 

 a certain extent the fibers, and condensing and delivering the 

 opened wool in a continuous strand or sliver. 



Carpet Wool. Low, coarse wool used in the manufacture of car- 

 pets. There is very little produced in the United States. 



Combing. 'An operation in worsted manufacture which 

 straightens the fibers and separates the short, weak, and tangled 

 fibers known as noils from the continuous strand of long parallel 

 fibers known as top. 



Come-back. In America this refers to a wool fine in quality 

 and having more length than would ordinarily be expected. In 

 Australia it is the result of breeding crossbreds back toward pure 

 Merinos, one of the parents being a pure Merino. 



Condition. Refers to the degree of oil in grease wool. It 

 largely regulates the price.* In scoured wool it is used to indicate 

 the degree of moisture. 



Cotted Fleeces. A cotted fleece is one in which the fibers 

 are matted or tangled'. The cause may be ill health of the sheep 

 or the absence of the proper amounts of yolk or grease in the wool. 



Cow Tail. A very coarse fleece, more like hair than wool. 



Crimp. The natural waviness of wool fiber. Uniformity of 

 crimp indicates superior wool. 



Crossbred Wools. In the United States the term generally 

 refers to wool from a long-wool and fine-wool cross. 



Defective. Denotes that something will show disadvantageously 

 after the wool is scoured. Fire, water, or moths may cause defec- 

 tive wools. California burry wool is quoted as defective. 



Delaine Wool. Delaine originally referred to a fine type of 

 women's dress goods. Delaine wools are fine combing or worsted 

 wools, from Ohio and vicinity, but not necessarily from the 

 Delaine Merino. 



Fall Wool. Wool shorn in the fall where shearing is practiced 

 twice a year, as in California and Texas. The fall wool is usually 

 dirtier than the spring clip. It represents from four to six 

 months' growth. 



Filling (Weft). Threads that run crosswise and' fill in between 

 the warp.
