Description
Technical Field

Background
With the rapid development of the preparation technology of the textile reinforcement, the tubular composite material is widely applied to the fields of aerospace, pipeline repair, medical appliances, sports goods and the like due to the fact that the tubular composite material is superior to the tubular metal material in specific strength and specific modulus. In order to meet the requirements of different industrial fields on the shape and the performance of the tubular composite material, the tubular fabric gradually forms a tubular fabric reinforcement with integrity and profile modeling from a single layer to multiple layers; the weft-knitted warp-inserted weft-inserted tubular fabric adopts weft knitting systems of weft plain needles, rib knitting mechanisms and the like, and monofilaments or compound yarns which are arranged in parallel are inserted in a specific direction to form a tubular reinforcement which has no turned edge and good formability, has a series of good mechanical properties, and provides a new application field for knitting axial products.
In the tubular reinforcement, the strength and stability of the fabric in both directions are enhanced because the non-looped straight yarns are inserted in both the transverse direction and the longitudinal direction, and the fabric has small longitudinal and transverse extensibility and has a weft knitting fabric with weaving and knitting characteristics. The lining warp yarn does not need to be bent into a loop, and can be woven by high-performance fibers such as aramid fibers, glass fibers, super-strong high-molecular polyethylene and the like which have high elastic modulus, high strength and low probability of bending, so that the functional fabric with higher tensile strength is produced. However, the movement of the sinkers of the single-sided circular knitting machine is controlled by a sinker cam, the sinkers play a role in assisting loop withdrawal and looping traction in the knitting process, but as the lining warp yarns are thick and gaps between adjacent sinkers are small, the lining warp yarns are fed between the adjacent sinkers, so that the problem that the lining warp yarns are abraded due to mutual friction between the sinkers and the lining warp yarns is easily caused, and the problems of unstable looping, silk hooking and the like possibly occur due to the fact that the operation space of the sinkers is extruded.
The solution adopted in patent application No. US346910 is to provide a circular knitting machine for knitting weft yarns comprising warp yarns and weft yarns interconnected by ground yarn loops. The machine comprises sinkers alternating with needles and each hook has a V-shaped mouth, the hook and the body of the sinker defining a throat therebetween. The mouth of the V contains the warp yarns when the sinkers are moved towards the axis of the machine, while the throat mentioned above contains the weft yarns therein when the needle head is guided behind the needles. Is lowered; the throat retains the weft and ground loop links when the needle is lifted. The ground, weft and warp guides are arranged in such a way as to ensure that the yarn is held firmly by the needles and the V-shaped mouths and throats of each sinker. Although the effect of co-weaving the lining warp yarns and the lining weft yarns is disclosed in the application document, the sinkers are arranged on the peripheral surface of the needle cylinder in the circumferential direction, the sinkers complete the co-weaving action of the lining warp yarns and the lining weft yarns, the structure is only suitable for the lining warp yarns with smaller diameters, if the lining warp yarns with larger diameters and thicker lining warp yarns are fed, the problem that the lining warp yarns are abraded due to mutual friction between the sinkers and the lining warp yarns is easy to occur, and the problems of unstable looping, silk hooking and the like due to extrusion of the operation space of the sinkers can also occur.

In the up-and-down reciprocating motion of the knitting needle, when the knitting needle hooks and pulls the front-end looped yarn downwards, the horizontal bearing surface 121 supports the rear-end looped yarn to be kept on the hooking and knitting working surface, so that the front-end looped yarn is looped and formed into looped yarn under the action of pulling down the knitting needle; when the knitting needle hook returns to the original position upwards, the back-end looping yarn on the horizontal bearing surface 121 pulls the looping yarn downwards to slide downwards relative to the knitting needle body to be released from the looping part of the knitting needle so as to realize looping; when the knitting needle hooks the looping yarn downwards again to form a new looping yarn, the previous looping yarn is propped against the horizontal bearing surface 121 to withdraw from the needle body of the knitting needle, and the looping withdrawing action is finished. According to the reciprocating action, the horizontal bearing surface 121 formed on the upper end surface of the needle groove wall 12 can assist the looped yarn to finish the actions of yarn bending, loop releasing and loop withdrawing, and replace the function of a sinker in the existing circular knitting machine, so that the knitting structure is simplified, and the operation difficulty is reduced.
