Description

Weaving method of polyester special trademark tape Technical Field The invention relates to a weaving method of a trademark tape, in particular to a weaving method of a polyester special trademark tape. Background The trademark tape is a small piece of fabric used as a commodity mark, and is continuously woven into a strip shape in production, and then cut into specified sizes according to requirements, wherein each small piece contains marks such as commodity marks, weaving factories, national names, specifications and the like. The trademark tape is generally woven by using high count bleached or colored cotton yarns, raw silk, polyester yarns, nylon yarns, rayon yarns, elastic nylon yarns, gold and silver yarns and the like as warp and weft yarns on a large-width machine, wherein a synthetic fiber material product is woven on a loom and is also finished through hot cutting processing. And the energy consumption is increased by adopting a thermal cutting mode, and if the blending proportion of materials is improper (such as the content of cotton is too high), or the cutting temperature and speed are controlled inaccurately, the edge is easy to be scattered and the silk is easy to be removed. In addition, the cut edges become stiffer than the fabric body due to melting, creating burrs, and are prone to scratch injuries during close fitting wear, affecting comfort. By adopting the mode of the selvedge mark, the edge warp yarns are not only required to bear opening movement, but also bear additional friction of the edge locking mechanism, so that the edge warp yarns are easy to fuzzing and break in high-speed reciprocating movement, stop is caused, and the production speed is reduced. Disclosure of Invention The invention aims to provide a weaving method of a polyester special trademark tape. The invention has the characteristics of no need of thermal cutting, difficult edge scattering and improvement of weaving efficiency and comfort level. The technical scheme of the invention is that the weaving method of the terylene special trademark tape comprises the following steps: S1, selecting terylene triangular special-shaped yarns as warp yarns; S2, respectively finishing warp yarns into weaving yarns and overlock yarns through warping, and then sizing and drying to ensure that the strength and the wear resistance of the overlock yarns are larger than those of the weaving yarns; s3, introducing the dried weaving yarns and the lockstitch yarns into a full-dull polyester yarn serving as weft yarns through a loom to perform shuttleless weaving and lockstitch, so as to obtain a blank belt; and S4, rinsing, desizing, drying and calendaring the embryo belt to roll the embryo belt to obtain the trademark belt with matte and bright contrast. In the aforementioned weaving method of the polyester special trademark tape, in step S3, the shuttleless weaving lockstitch is that weft yarns on upper and lower layers are introduced through a weft needle through a swinging motion to push to a weaving port to form a compact fabric structure ‌, when the weft needle finishes beating up and withdraws, the ‌ lockstitch immediately acts to hook the lockstitch yarn to perform the actions of reciprocating hooking, looping and looming ‌, a continuous loop chain is formed at the fabric edge, and the ends of the weft yarns on double layers are effectively fixed to prevent loose. In the weaving method of the polyester special trademark tape, in the step S2, the sizing rate of the overlock yarn is larger than that of the weaving yarn. In the weaving method of the polyester special trademark tape, in the sizing process of the step S2, sizing equipment is adopted for treatment, the sizing equipment comprises a sizing groove, a front immersing roller, a front sizing roller set, a rear immersing roller and a rear sizing roller set are sequentially arranged in the sizing groove, the working face of the front sizing roller set is positioned in slurry, the working face of the rear sizing roller set is positioned outside the slurry, the pressure of the front sizing roller set is lower than that of the rear sizing roller set, the front sizing roller set comprises an upper front pressing roller and a lower front pressing roller, the rotation directions of the front immersing roller and the rear immersing roller are consistent, the rotation direction of the lower front pressing roller is opposite to that of the front immersing roller, one end of the front immersing roller is provided with a first stirring wheel, one end of the rear immersing roller opposite to the front immersing roller is provided with a second stirring wheel, and two ends of the lower front pressing roller are respectively provided with a third stirring wheel. In the weaving method of the terylene special trademark tape, the pressing roller is arranged above the upper front pressing roller and is rotationally connected to the sizing groove, the pressing roller is driven by the rotati
