Claim 11
Dependent Claim
25 words
The tubular sleeving of claim 1, wherein said principal braid comprises flexible filaments selected from the group consisting of polyesters, nylons, aramid polymers, and polytetrafluoroethylene.
Claim 12
Dependent Claim
28 words
The tubular sleeving of claim 1, wherein said braided ribs are oriented at an angle of about 45 degrees relative to a longitudinal axis of said tubular sleeving.
Claim 13
Dependent Claim
18 words
The tubular sleeving of claim 1, further comprising: a protective coating adhered to a surface of said sleeving.
Claim 14
Dependent Claim
13 words
The tubular sleeving of claim 12, wherein said coating comprises an acrylic resin.
Claim 15
Dependent Claim
11 words
The tubular sleeving of claim 12, wherein said coating comprises vermiculite.
Claim 16
Dependent Claim
20 words
The tubular sleeving of claim 14, wherein the weight of the coated sleeving comprises about 2% to about 20% vermiculite.
Claim 17
Dependent Claim
12 words

Claim 22
Dependent Claim
36 words
The tubular sleeving of claim 1 that is coated with vermiculite from a dispersion of vermiculite particles, the coating in an amount in the range of about 2 to 20 percent by weight of the sleeve.
Claim 23
Dependent Claim
36 words
The tubular sleeving of claim 21 in which the vermiculite coating is further coated with an acrylic adhesive in an amount in the range of about 6 to 10 percent weight adhesive based on sleeve weight.
Claim 24
Dependent Claim
122 words
The tubular sleeving of claim 21 in which the vermiculite coating is applied by moving the sleeving through an aqueous dispersion of vermiculite under conditions of dispersion concentration and moving speed sufficient to obtain a solids content of vermiculite in the range of 2 to 20 percent by weight of the sleeving, an acrylic content on the range of 5 to 20 percent by weight of the sleeving, and drying the sleeving in a vertical heated furnace by passing the sleeving through the furnace at a rate in the range of 1.5 to 4 feet per minute, the furnace being maintained with a temperature profile ranging from about 60° C. at the braid inlet to about 180° C. at the braid outlet.
