Vat dyes may be conveniently applied to a wider variety of fabrics than ever before by means of the Multi Lap machine, developed by the DuPont Company's Dyestuffs Division. A working model of the machine is being demonstrated here by William M. Wentz, right, inventor of the machine and G.T. Hug, both of the company's Dyestuffs Division. The fabric enters at right and is carried into and out of the dye bath a number of time by means of multiple laps around an endless conveyor, which subjects...

The fabric enters at right and is carried into and out of the dye bath a number of time by means of multiple laps around an endless conveyor, which subjects it to a minimum of stretching or distortion. The cloth finally emerges from the center of the apparatus.

- Description
-
For the most part, textile fibers-natural and man made- have wide varying physical and chemical properties. The differences are apparent in the types of dye which adhere to the fibers. By mixing or blending fibers with different dyeing characteristics in the same fabric, the result is cross dyeing, each fiber picking up its particular dye in the bath or chamber and disregarding the others.

A working model of the apparatus is here being demonstrated by Meadows S. William s, Jr. at the left and Dr. R.J. Thomas, both of the company's Technical Laboratory. The cloth enters at the left, picking up the insoluble dyestuff in a pigment padder, then goes through the flue dryers. Chemicals are applied in the second padder in the center and the dye is finished in the steam chamber, at the right. The color which has now penetrated into to the fabric, changes back into its permanent insoluble form.

- Date(s)

- Description
-
Raw cotton, due to the presence of natural waxes and fats, is quite resistant to wetting by ordinary water, but the addition of a small amount of certain chemicals, known as wetting agents, causes the cotton to become wet rapidly. Wetting agents are accordingly used to speed up various textile operations which involve wetting-such as souring cleaning and dyeing.
