Description
Technical Field
The invention relates to the technical field of textile engineering, in particular to a processing device for multi-needle-track compound braiding.
Background
The fancy yarn is produced by adopting special fiber raw materials or an unconventional processing method, and has decorative yarns with special structures and appearance effects, such as color gradient yarns, section color yarns, positioning coating bunchy yarns, novel connector yarns, novel friction spinning yarns, intelligent yarns and the like.
With the development of fancy yarns, the fancy yarns are widely applied to fashion fabrics, home textile fabrics, knitted garments, garment decorations and the like. In recent years, small cylinder-knitted tape yarns have gradually become the main stream of fancy yarn, which has been extended with many new varieties such as core-spun tape yarns, colored-spot tape yarns, slub tape yarns, spiral tape yarns, spray Mao Daizi yarns, lash tape yarns, and the like. The belt yarn is light and fluffy, has good hand feeling, no coil loosening, and the woven fabric and clothing have clear texture and good drapability. The tape yarn has short production flow, high yield and lower cost.
The fineness of the tape yarn is determined by the fineness of the yarn woven by the tape yarn and the number of knitting needles. The finer the yarn, the fewer the needles, the finer the tape yarn, and the higher the count (linear density) thereof. The special refinement of the belt yarns needs to break through the limit of the number of lifting systems of the needle cylinder, the diameter of the needle cylinder and the number of latch needles.
The 3 latch needle inward rotating type small needle cylinder with small diameter and single lifting system is used for braiding extra fine belt yarn. The smaller the syringe diameter, the steeper the slope of the knitting cam mechanism. When the slope is too steep, the latch needle is easy to self-lock in the triangular mechanism, the latch needle cannot reach the yarn-laying position, and the yarn cannot be looped; when the latch needle is in a low position, the needle point is 1.5-2 mm away from the upper end of the needle cylinder, and the height difference is fixed when the latch needle moves up and down in the needle cylinder, and the minimum value is 1.5mm.
The fineness of the knitting yarn, the yarn amount for a single stitch, the number of needles to be knitted, and the like must be reduced in order to weave an extremely fine tape yarn. The appropriate spun yarn is selected to reduce the fineness of the tape yarn. If tape yarns are to be woven, the latch needle number of the needle cylinder must be more than 3, i.e. the number of loops of the tape yarn cross section is at least 3. The yarn usage of the single loop and the diameter of the tape yarn are determined by the diameter of the needle cylinder and the number of lifting systems. The smaller the syringe diameter, the finer the diameter of the tape yarn. The fewer lifting systems for knitting the tape yarns, the fewer knitting cam mechanisms, the smaller the slope height of the cam, the smaller the stitch depth of latch needles when knitting loops, and the smaller the yarn consumption of a single loop.
In order to break through the defects, a braiding needle cylinder with small size, multiple needle tracks and diversified tracks is designed and processed, and the braiding needle cylinder is an effective method for realizing special refinement and diversified braiding of belt yarns.
