Patent number: 5855125Abstract: A method of constructing a double face fabric is provided. The first step in the method is to knit a three dimensional knit fabric which has a first fabric layer, a second fabric layer and a plurality of yarns that interconnect the two layers. The three dimensional knit fabric is prepared using a conventional double needle bar warp knitting machine. Then, the yarn connecting the two layers is cut, resulting in two pieces of fabric having a velvet surface on one side, and a flat knit surface on the other. The flat knit surface is then raised by a process such as napping to pull portions of the pile yarns through the fabric layer to the technical back, in order to form a pair of double face fabrics, each with a first velvet surface and a second fleece surface. Preferably, the fabric is knit so that after napping it can be stretched. In this manner a wide variety of fabrics can be created.Type: GrantFiled: September 26, 1997Date of Patent: January 5, 1999Assignee: Malden Mills Industries, Inc.Inventors: Karl Lohmueller, Moshe Rock, Douglas Lumb

Patent number: 4199633Abstract: A double knit fabric includes a plurality of courses knitted to form first and second sets of alternating wales. The first set of alternating wales forms the face of the fabric while the second set of alternating wales forms the reverse side of the fabric. The courses are knitted in a preselected pattern to form stitches which join the courses together at selected wales. First yarns are used to form selected courses with the first yarns having a higher shrinkability than second yarns forming the remainder of the courses. Selected second yarns are knit in a pattern which allows portions of the second yarns to float on the face of the fabric. The floating portions are formed by causing the yarn to welt or miss at least two consecutive wales of the first set of alternating wales.Type: GrantFiled: May 16, 1978Date of Patent: April 22, 1980Assignee: Phillips Petroleum CompanyInventor: James H. Blore

Patent number: 4136221Abstract: Disclosed is a suede-like raised woven fabric of a combination weave having raised extra fine fibers on the surface thereof, which fabric comprises a continuous multifilament yarn used as warp, a yarn of a bundle comprising continuous extra fine filaments used as a first weft and a continuous multifilament yarn used as a second weft. The preparation of the raised fabric comprises weaving a fabric using appropriate material yarns, subjecting the fabric to heat treatment and subjecting the fabric to raising. The yarn constituting the first weft may be produced from a bundle of multi-core composite filaments by removing a component surrounding the cores. The fabric has an excellent suede-like touch, appearance and feel.Type: GrantFiled: December 2, 1977Date of Patent: January 23, 1979Assignee: Toray Industries, Inc.Inventors: Miyoshi Okamoto, Syusuke Yoshida
