The invention provides a circular knitting machine for prompting a knitting machine status instantaneously based on a cloth surface status of a fabric, comprising a needle cylinder, a camera module capable of photographing the fabric during doffing, an information processing unit, and an encoder. A camera lens of the camera module does not rotate with the needle cylinder, and a shooting timing of the camera lens is controlled by photographing signals. The information processing unit receives image data generated by the camera module, and compares the images, when there is a difference between the two consecutive image data on a same vertical line, a knitting machine status is prompted. The encoder generates pulse signals when the needle cylinder rotates, the encoder outputs the pulse signals to the camera module or the information processing unit, and the receiver counts the pulse signals to generate the photographing signals.

A needle-holding element for circular knitting machines, having a structure as a hollow solid of rotation developing around a central axis and configured for rotating and for supporting a plurality of needles moving so as to produce a knitted fabric; the needle-holding element has at least one working surface shaped as a surface of rotation obtained through the rotation of a portion of generating straight line around the central axis; on the working surface a plurality of needle seats is defined, placed one beside the other and arranged circumferentially or radially around the central axis, wherein each needle seat movably houses at least a portion of at least one respective needle. At least one needle seat has at least a first length has a longitudinal development, on the working surface, inclined with respect to the generating straight line.

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.
