Abstract

Abstract Apparatus is disclosed herein for the liquid treatment of textile materials. Specifically, the liquid treating apparatus comprises a vessel in which are positioned a plurality of textile guides. The textile guides define a fabric path through the vessel and are positioned along both sides of the path. Fluid movement means such as a polygonal shaped rotatable element, especially a triangular shaped rotatable element is positioned adjacent the fabric path and acts on fluid in the vessel to create undulations in the textile material around certain of the guides as the textile material passes thereby. Preferably, the textile material follows a U shaped path through the vessel. Ancillary apparatus is also disclosed as well as a method for the liquid treatment and bulking of textile fabrics, especially knit fabrics.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 103 words
Fabric treating apparatus comprising: a. a treating vessel; b. a plurality of fabric guides received within said vessel to be submerged in a treating liquid received therein, said guides defining a fabric path through said vessel and being positioned on both sides thereof; and c. a rotatable element received in said vessel adjacent at least certain of said guides and out of contact with a fabric passing thereby during rotation thereof, said element having positive and negative pressure producing areas thereon and cooperating with said guides during rotation whereby adjacent liquid flow in opposite directions causes undulation of said fabric about said guides.
Claim 2
Dependent Claim 103 words
Fabric treating apparatus comprising: a. a treating vessel; b. a plurality of fabric guides received within said vessel to be submerged in a treating liquid received therein, said guides defining a fabric path through said vessel and being positioned on both sides thereof; and c. a rotatable element received in said vessel adjacent at least certain of said guides and out of contact with a fabric passing thereby during rotation thereof, said element having positive and negative pressure producing areas thereon and cooperating with said guides during rotation whereby adjacent liquid flow in opposite directions causes undulation of said fabric about said guides.
Claim 3
Dependent Claim 21 words
Fabric treating apparatus as defined in claim 1 wherein said fabric guides define a U shaped fabric path in said vessel.
Claim 4
Dependent Claim 24 words
Fabric treating apparatus as defined in claim 2 wherein fabric guides are positioned on both sides of each leg of said U shaped path.
Claim 5
Dependent Claim 16 words
Fabric treating apparatus as defined in claim 3 wherein said rotatable element is triangular in shape.
Claim 6
Dependent Claim 16 words
Fabric treating apparatus as defined in claim 1 wherein said rotatable element is polygonal in shape.
Claim 7
Dependent Claim 16 words
Fabric treating apparatus as defined in claim 5 wherein said rotatable element is triangular in shape.
Claim 8
Dependent Claim 20 words
Fabric treating apparatus as defined in claim 6 wherein said rotatable element is positioned between the legs of said U.
Claim 9
Dependent Claim 25 words
Fabric treating apparatus as defined in claim 1 wherein said fabric guides define a fabric path that makes more than one pass through said vessel.
Claim 10
Dependent Claim 20 words
Fabric treating apparatus as defined in claim 8 wherein a rotatable element is provided for each pass through said Vessel.
Claim 11
Dependent Claim 38 words
Fabric treating apparatus as defined in claim 8 wherein a plurality of U shaped paths are defined by said guides and wherein further a triangular shaped rotatable element is provided between the legs of each U shaped path.
Claim 12
Dependent Claim 18 words
Fabric treating apparatus as defined in claim 1 wherein said vessel is further provided with liquid heating means.
Claim 13
Dependent Claim 19 words
Fabric treating apparatus as defined in claim 1 comprising further: d. fabric supply means; and e. fabric drying means.
Claim 14
Dependent Claim 24 words
Fabric treating apparatus as defined in claim 12 wherein said fabric supply means comprises a scray and a spreader roll mounted adjacent said vessel.
Claim 15
Dependent Claim 19 words
Fabric treating apparatus as defined in claim 12 wherein fabric supply means comprises a conveyor mounted adjacent said vessel.
Claim 16
Dependent Claim 132 words
Fabric treating apparatus comprising: a. fabric supply means; b. a first vessel adjacent said fabric supply means; c. a driven roll above said vessel for accepting fabric therefrom; d. fabric collection means adjacent said driven roll; e. fabric spreader means adjacent said fabric collection means; and f. a second treating vessel, said vessel having a plurality of fabric guides therein said guides being submerged in a treating liquid received in said vessel and defining a fabric path through said vessel, being positioned on both sides of said path, said vessel further having a rotatable element received therein adjacent at least certain of said guides, said element having positive and negative pressure producing areas thereon and cooperating during rotation with said guides to produce undulation of a fabric passing along said fabric path.
Claim 17
Dependent Claim 132 words
Fabric treating apparatus comprising: a. fabric supply means; b. a first vessel adjacent said fabric supply means; c. a driven roll above said vessel for accepting fabric therefrom; d. fabric collection means adjacent said driven roll; e. fabric spreader means adjacent said fabric collection means; and f. a second treating vessel, said vessel having a plurality of fabric guides therein said guides being submerged in a treating liquid received in said vessel and defining a fabric path through said vessel, being positioned on both sides of said path, said vessel further having a rotatable element received therein adjacent at least certain of said guides, said element having positive and negative pressure producing areas thereon and cooperating during rotation with said guides to produce undulation of a fabric passing along said fabric path.
Claim 18
Dependent Claim 47 words
Fabric treating apparatus as defined in claim 15 wherein said fabric guides in said second vessel defined at least one U shaped path therethrough and wherein said rotatable element is triangular in shape and is positioned between the legs of said at least one U shaped path.
Claim 19
Dependent Claim 37 words
Fabric treating apparatus as defined in claim 1 wherein certain of said guides are positioned tangent to a circle around said rotatable element, said circle being positioned at a point just out of contact with said element.
Claim 20
Dependent Claim 16 words
Fabric treating apparatus as defined in claim 17 wherein said rotatable element is triangular in shape.
