Embodiment Construction

[0037] 1. Outline of circular knitting machine

[0038] figure 1 It is an overall view of a knitting machine, showing two types of first yarn feeding device 10 and second yarn feeding device 20, first driving wheel 11 and second driving wheel 21 for driving the yarn feeding device, and a plurality of machine feet 30. The needle bed 40 supported by the machine foot 30, and the knitting section 50 arranged on the needle bed. The first yarn feeding device 10 and the second yarn feeding device 20 are driven from the first driving wheel 11 and the second driving wheel 21 via a driving belt, but the driving belt is not shown for convenience.

[0039] Although not shown, the knitting unit 50 accommodates a plurality of cylinder needles in the needle grooves of the cylinder that can slide in the vertical direction. The cam seat which is opposite to the syringe and has a needle for controlling the syringe is installed on the cam seat supporting ring. As will be described in detail l...

Abstract

A method for knitting a slit yarn made of a sheet-like raw material and having a width of several millimeters by a knitting machine while covering a core yarn with the slit yarn, an apparatus used therefor and a knit fabric obtained thereby are provided. A slit yarn feeding device is provided for feeding a slit yarn (SY), separately from a yarn feeding device for feeding a core yarn (CY). A covering means (80) for wrapping the core yarn (CY) in the slit yarn (SY) is provided between the slit yarn feeding device and a knitting portion (50). Also provided is a guide means (12, 61, 63) for guiding the slit yarn (SY) from the slit yarn feeding device to the covering means (80) such that the slit yarn (SY) will not be twisted and will not crease, and a front and back thereof will not be inverted.

Description

technical field [0001] The present invention relates to a method of knitting with a knitting machine while covering a core yarn (core yarn) with a sheet-like material such as a film or nonwoven fabric with a slit yarn (slit yarn) with a width of several mm, and the yarn used in the method. device and the resulting knitted fabric. Background technique [0002] Conventionally, knitting machines knit using knitting yarns obtained by weaving and false-twisting chemical staple fibers and filaments called natural fibers or chemical fibers. In recent years, a flat material called slit film has been developed, and sheet-like raw materials such as non-woven fabrics with a structure in which films and fibers made of polypropylene or polyethylene are arranged in parallel or indefinitely are laminated. Cut to a width of several mm to form a slit film. [0003] It should be noted that the filament yarn that has not been crimped in a synthetic fiber manufacturing plant is called a flat ...
