This invention relates to improvements in or
relating’ to effect materials, and particularly to
arti?cial ?lms, sheets and similar materials ex
, hibiting mother-of-pearl or other effects.
This application is a continuation in part of
my application S. No. 83,328 ?led June 3rd, 1936.
It has been discovered that materials exhibit
ing excellent ornamental effects may be obtained
by causing the pile side of a pile fabric to adhere
1° to a'translucent or transparent arti?cial ?lm or
similar material and thereafter separating the
pile fabric from the ?lm.

of cotton or linen yarn. Where it is desired to
eife'ct relatively strong adhesion between the-pile
fabric and the ?lm it is preferable that the pile
of the fabric should be made of the‘ same sub- ;
stance or a similar substance to the material of
'thei?lm; Thus there may be adhered to a ?lm
having a basis of an organic derivative of cellu
lose a pile fabric which has a pile of an organic
derivative of cellulose. Where, on the other hand,
it is desired to effect only light adhesion, the pile
of the fabric is preferably made of a ‘different
material from the material of the ?lm, e. g. a
cellulose derivative film may be caused to adhere
to a pile fabric in which the pile is made of re-v

It is not necessary, however, that the pile fab
tyrate, cellulose .nitro-acetate, methyl cellulose,
"ethyl cellulose,.benzyl cellulose, and particularly
cellulose acetate, have been .found to be specially
valuable. Such materials, especially if they have
_ 40 a high content of substituent groups, e. g. in the
case of cellulose acetate corresponding to an
.acetyl content of 56-58% or more, are'relatively
moisture-resistant, which is of considerable value
for certain purposes.
However, ?lms of other
45 ' substances may be employed, e..g. ?lms having a
basis of a polymerized vinyl acetate, a polymer
ized acrylic ester or ether or other synthetic
resin.

fabric of uniform character, the pressing opera 40

Adhesion between the pile fabric and the trans
parent ?lm may be effected in any suitable man 45
ner. When the material of the ?lm and/or the
materlal of the pile of the pile fabric are thermo~>
