The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.

A method for modeling textile structures using bicontinuous surfaces includes selecting a virtual scaffold of bicontinuous surfaces defining textile fabrication pathways to model spatial relationships between the pathways and yarns in a desired yarn pattern of a textile fabric design. The method further includes constructing a yarn pathway across the bicontinuous surfaces that form the virtual scaffold. The method further includes removing or releasing tension from the virtual scaffold, thereby allowing yarns to relax and determining a physical property of the textile fabric design.

The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine, and belongs to the technical field of warp knitting equipment. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. According to a current position of each guide bar, a target position of current shogging of an original pattern and a starting course position of a novel pattern, a control system of the double needle bar warp knitting machine automatically calculates a shogging displacement required by each guide bar in a pattern loading process, and sends out instruction information to a shog driving execution unit corresponding to each guide bar. In a respective underlapping interval allowed of each guide bar, the corresponding guide bar is respectively driven by the shog driving execution unit to respectively and precisely move to the starting course position of the novel pattern to complete the electronic shogging pattern loading. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.

A flat knitting machine mangling device with position varying with gap size is provided. The flat knitting machine mangling device includes a driving element, a fixing base disposed on a cam supporting base, a sliding base disposed to correspond to the fixing base, a limiting block combined with the fixing base and limiting the sliding base to only slide relative to the cam supporting base, a mangling sheet supporting arm and a mangling sheet disposed on the mangling sheet supporting arm. The driving element is started when a knock-over bit cam makes a displacement stroke. The sliding base is provided with a guide block and makes a regulation stroke relative to the cam supporting base when the driving element is started. The guide block drives the mangling sheet to move to change a mangling position when the sliding base makes the regulation stroke.

A method for knitting a three-dimensional fabric with variable thickness through a flat knitting machine includes the following steps: moving two cam groups and driving a plurality of knitting needles to knit a first piece of knitting by a starting cam system; moving the two cam groups and driving the plurality of knitting needles to knit a second piece of knitting by a middle cam system; and moving the two cam groups and driving the plurality of knitting needles to knit a supporting yarn by two tail cam systems respectively. The tail cam systems control each of a plurality of knock-over bit cams to move according to a gap size corresponding to a knitting length of the supporting yarn, so as to promptly change a thickness of the three-dimensional fabric along the length change of the supporting yarn.

An item may include fabric or other materials formed from intertwined strands of material. The strands of material may include non-conductive strands and conductive strands. The strands may be intertwined by a warp knitting machine to produce a warp knit fabric. The warp knit fabric may include intertwined warp strands and weft insertion strands that are inserted amongst the warp strands. The weft insertion strands may extend across less than all of the warp strands. The weft insertion strands may include parallel segments that each extend across a different portion of the warp strands. The segments of weft insertion strands may have different widths relative to one another and relative to the width of the fabric. The weft insertion strands may be inserted into the warp knitting machine across the warp strands using a weft insertion device that is positioned by a computer-controlled positioner.
