Title: Double pile weave - has divided shed structure in pairs for a twin-weft weaving with the same quality as a triple-weft material
Inventor: GOESL RAINER DR SC TECHN
IPC: D03D39/16
Filed: 1992-07-01
Abstract: To produce a double pile weave, where the fabric layers are cut at their linking piles, the warps of the upper fabric (KO,STO) form an initial pair (A) of shed planes (A1,A2), and the warps of the lower fabric (KU,STU) form a further pair (B) of shed planes (B1,B2). The two pairs (A,B) of shed planes are separated at the weft insertion zone. In the first weaving cycle, one pair (A or B) takes additionally a patterning pile (P) and one pair (A or B) takes a bonding warp (KO or KU) from the other fabric. A weft is inserted simultaneously between the shed planes (A1,A2 or B1,B2) of at least one pair (A or B) and between both pairs (A,B). In the second weaving cycle, the second pair (B or A) additionally takes the patterning pipe (P), and the pair (B or A) which has only one bonding warp takes an additional warp (KO or KU) from the other fabric. A further weft is inserted simultaneously between the shed planes of at least one pair (A or B) and between the pairs (A,B). Also claimed is a double pile woven material where each warp has at least one double warp for each repeat in each fabric layer, held by a single outer weft and a double inner weft. USE/ADVANTAGE - In weaving a double pile fabric structure, the system uses a twin weft with the same quality parameters as a triple weft, with the productivity of a twin weft operation, with less yarn breakage, and reduced drives, in a stable fabric without clouded patterning.
