194 BARRED GOODS. 



CORDED FABRICS. 



Tissue and vellum are made very strong, (and are difficult to 

 be torn,) when corded with silk, thread, twine, or spun-yarn, for 

 the same reason that muslins and other woven fabrics are 

 strengthened by being barred or corded with threads stronger 

 than those of which the cloth is made. 



The different fibrous fabrics, when corded in this manner, 

 are even stronger than India rubber fabrics that are made of 

 woven cloths. The uses of these fabrics are the same as those 

 of tissue, vellum, and vegetable leather ; but on account of their 

 great strength, they are more extensively applicable to many 

 purposes for which those fabrics would not answer, such as ships' 

 sails, tarpaulins, coach cloths, &c. 



The great recommendation of these goods is, that they possess 

 the greatest strength with the least possible weight, at the same 

 time that the gum does not peel or chafe from them as it does 

 from coated cloths. 



BARRED GOODS. 



These consist of various articles made of the vulcanized 

 fabrics, which are strengthened by narrow bands or strips of 

 coated canvas, which are cemented upon the outside of the 

 articles or fabrics in a sort of net-work. By these means a 

 lighter fabric can be made use of for any given purpose than 

 otherwise could be, and the greatest strength is thereby obtained 

 with the least weight. The wear of the articles made in this 

 way comes very much upon the bands, which makes them better 

 adapted for ships' sails, tents, mail-bags, awnings, &;c., than the 

 plain fabrics.* 



* Of this fabric, manufactured from a light and inferior article of cotton duck, a topsail of the 

 packet ship " Stephen Whitney" was made ; for a report upon the qualities and performance of 

 which, the reader Is referred to the letters of Capt. Popham, page of this work.
