11549203 · 2023-01-10 · ·

A method for manufacturing a cut resistant fabric includes: supplying a polyethene yarn with a thickness of 50-225 dtex as a protective yarn through a first yarn carrier of a circular knitting machine to a feeder needle at a first selected tension; supplying simultaneously an uncoated elastane yarn with a thickness of 20-80 dtex as a first additional yarn through a second yarn carrier of the circular knitting machine to the same feeder needle at a second selected tension that is higher than the first selected tension of the protective yarn; forming a fabric from the protective yarn and the first additional yarn as single-jersey knits; and interlocking the protective yarn and the first additional yarn in each single-jersey knit of the fabric using a heat treatment step on a stenter frame.

KNITTING METHOD AND APPARATUS FOR CYLINDRICAL BIAXIAL WEFT-KNITTED THREE-DIMENSIONAL KNITTED STRUCTURE
20170321356 · 2017-11-09 ·

A knitting method and an apparatus for a cylindrical biaxial weft-knitted three-dimensional knitted structure. The biaxial three-dimensional knitted structure comprises two weft plain stitch structures (7, 7′), a group of spacer yarns (416), two groups of weft inserting yarns (415, 415′) and a group of warp inserting yarns (43), wherein the two groups of weft inserting yarns are used for selective weft inserting on a needle dial (11) or a needle cylinder (13), the warp inserting yarns are positioned between the two groups of weft inserting yarns, the two weft plain stitch structures are connected with each other by the group of spacer yarns, for jointly clamping the weft inserting yarns and the warp inserting yarns, in order to form a biaxial weft-knitted three-dimensional knitted structure. Such three-dimensional knitted structure improves the mechanical properties of three-dimensional knitted fabrics; by increasing the interval between the needle dial and the needle cylinder, the thickness of the knitted structure is increased, which is suitable for the reinforced structure of high-performance structural and functional composite materials, and expand the field of the use of the knitted structures.

KNITTING MACHINE WITH A SINKER AND BIASED CAM MEMBER FOR ACTUATING THE SINKER
20170321358 · 2017-11-09 · ·

A knitting machine may include a sinker configured to move between an open position and a closed position. The knitting machine may have a sinker actuator system having a first configuration and a second configuration. The sinker actuator system, in the first configuration, may be configured to actuate the sinker from the open position toward the closed position. The sinker may be configured to change the sinker actuator system from the first configuration to the second configuration when the sinker receives an input force above a predetermined threshold in the movement from the open position toward the closed position. The sinker actuator system, in the second configuration, may allow the sinker to move away from the closed position toward the open position.
