The preparation process of the blended high-density flame-retardant fabric comprises the following steps:
s1 warping process: the flame-retardant blended yarn is sequentially led out from the cone yarn to form a yarn sheet, so that warp yarns have uniform tension and are tightly wound on a warp beam in parallel;
s2 sizing step: sizing by using a Jintian colt HS30 type sizing machine, wherein the temperature of a size box is controlled at 90 ℃, the temperature of a drying room is controlled below 100 ℃, and the temperature is 95 ℃ which is an appropriate temperature; the flame-retardant warp yarns respectively pass through the two size tanks and the four drying cylinders, so that the warp yarns are uniformly sized, and the size film is complete and flexible; the hairiness is reduced, the strength is increased, and the weaving requirement is met; and is tightly wound on the sizing shaft through the yarn separating plate in sequence;
s3 drawing-in step: the drawing-in procedure adopts a full-automatic reeding machine, sequentially passes through a dropper, a harness wire and a reed according to the technological requirements of the fabric, and adopts a forward drawing-in method and four-in. The drawing of the reeding and drafting is shown in figure 1.
S4 weaving process:
adopting an air jet loom of the Japanese Jinju, wherein the opening time is 290 ℃, the back beam height is 55mm, the let-off time is 310 ℃, the let-off tension is 3000N, the vehicle speed is 500 r/min, and the production process of large tension and small opening is adopted; the height of the back beam and the warp stop frame is increased, and the back beam is pushed forwards; through the matching of 5-size weaving systems such as opening, weft insertion, beating-up, reeling-up and let-off, as shown in figure 1, the warp and weft yarns are interwoven into a honeycomb fabric according to the design requirements. In the weaving process, according to the characteristic that yarns are easy to brittle break and have less hairiness, the process of high back beams and late weft insertion is adopted, and the elastic barbed temple is adopted to reduce the weft shrinkage of the cloth cover. The grey fabric is inspected, measured and repaired, using a package.
