![[List of Patents for class 28 subclass 103]](../ps.gif) 103 | Fiber entangling and interlocking: |
| | This subclass is indented under subclass 100. Method or apparatus wherein the component members of a nonwoven
textile article or structure are rearranged to intermingle, one
with the other, and are held in such intermingled condition by interfiber
friction existing therebetween.
| | (1)
Note. The term "nonwoven" as utilized herein
includes a textile article or structure assembled by operations
other than weaving, knitting, braiding, lacing, knotting, or sewing,
particularly including a textile article or structure assembled
by needling, felting, cross-laying (not found in this subclass),
and combinations thereof. |
| | (2)
Note. The term "fiber" as utilized herein generally
intends the fundamental unit of determinate, i.e., staple, length
in the preparation of a textile article or structure but may also
include a thread of substantial determinate or indeterminate length
which is either used in the preparation of an individual needled
or felted nonwoven article or structure or as a nonwoven entity
of a composite needled or felted nonwoven article or structure. |
| | (3)
Note. Fiber entangling and interlocking of a thread or a thread
interlaced article or fabric, per se, as by needling or felting for
example, is excluded from this subclass since such treatment operations serve
to enhance or embellish rather than to create or establish the textile
article or structure. However, the preparation of a base, layer,
or substrate by a thread interlacing operation, such as by weaving, knitting
and the like, which base, layer, or substrate is subsequently utilized
in the manufacture of a composite nonwoven article or structure,
is included herein. |
| | (4)
Note. Fiber entangling and interlocking by subjecting a nonwoven
textile structure under tensionless conditions to the influence
of a fluid medium to develop latent shrinkage tendencies of the
component members thereof, i.e., relaxation after treatment, is
found herein. |
