FOUNDATION OF AN INDUSTRY
The arrangement of loops used in knitting stockings on a machine is the same as that used in hand-knitting.
Fig. 1 is a knitted loop, a very simple thing in principle.
It is not known who invented knitting, and at what date, nor is it known in what country it originated, but this loop is the foundation of an industrywhich has provided a livelihood for thousands of workers in all countries, whether the goods produced be hand–knitted or made on a machine.
The knitted loop has by the nature of its structure this important property, that when the loop is disturbed by stretching, the principle of balance equality is at once established, and each loop in the knitted fabric immediately seeks to right itself by returning to its original position. Therefore, the loops themselves are elastic by reason of the fact that each loop hangs on another, and each row of loops on anotherrow, and so all loops are united.
This principle of equilibrium solves the basic problem of the stocking fabric, the elasticity of the loop providing that gentle stretch which is essential for the securing of a perfect fit despite all movements of
