perspiration-fastness test requirements.

The test is simple, since a cloth, with floating yarns of wool, cotton, rayon, acetate and nylon, is saturated with synthetic perspiration and placed in contact with the upholstery fabric under sufficient pressure to insure firm contact. This condition is maintained for one-half hour at a temperature of 100: F., after which the test cloth is examined. If all the floating yarns are free of color, the material is satisfactory. In some instances, only one or two kinds of yarn will be affected, while the others remain unchanged. This condition indicates that the yarns are susceptible to color transfer; a garment made of that kind of yarn, which comes in contact with a perspiration condition, will be soiled, probably permanently. Expensive claims can be avoided by close attention to this matter.

Pile Anchorage

Some fabrics, made with a V-weave construction and without rubberized backing, will shed the pile tufts, leaving bare spots in the backing of the fabric when it is subjected to the use and abuse of public seating. Such a weakness in

this type of pile fabric can be hurriedly detected by stretching a piece of the fabric between both hands while the thumb pushes the ends of the piles on the face side of the fabric. If the pile leaves the face and comes through the backing, there is an indication that it will be weak in pile anchorage. There are fabrics which have high pile and thread counts that cannot be defaced this way, for the crowded condition of the pile tufts resist such damage. It pays to use a fabric with a W-weave, one with a V-weave and a rubberized back, or a type with a high-pile count for sideboxing of seat cushions.


Imitation leathers, defined in this article to mean only fabric - coated materials, and not the unsupported film types which are not suitable for public seating where there is iiexing present, come in for their share of scrutiny also as chair covering materials. Just as with the pile fabrics, the manufacturer who intends to use them to upholster his products must take a number of questions under consideration. Some of the points to be raised in connection with an

TRIE- ADHESION TEST turnishes important data on so-called imitation leathers, tor much at their workability and future life depends on the backing materials and the way in which the coating adheres.


CAN IT RESIST clothing abrasion and edge wear?

imitation leather are as follows:

1. Does it have sufficient abrasion resistance?

2. How long can it be used under various conditions before it becomes hard and brittle?

8. Is there sufficient anchorage between the coating and the backing?

4. How good are its fiexing and folding characteristics?

5. Does it. crock?

6. What about color transfer to clothing when perspiration is present?

7. What are its stretch and strength values?

8. Is it resistant to the effects of popcorn oils, greasy clothes, and body oils?

9. Does its finish permit easy ingress and egress?

10. Is it pliable, and does it make up well on a cushion?

Although tests for abrasion resistance, crocking, perspiration fastness, stretch and strength values, etc., similar to those used to evaluate pile fabrics, are given
