Upper and lower layers of fleece.

Preferably, the simultaneous cross-weaving of the above-mentioned fleece and the upper and lower layers of base fabrics is to alternately extend the two continuous velvet warps forming the upper and lower layers of base fabrics into the upper and lower layers of base fabrics, respectively along the ground warps of the two layers of base fabrics, Pass between the weft yarns of the upper and lower base fabrics. After passing through three weft yarns, at the corresponding position of the fourth weft yarn, the two suede warps cross and transpose once between the upper and lower base fabrics, and then extend into the two weft yarns respectively. In the bottom layer, enter the next cycle.

Preferably, the above-mentioned weft threads of the upper and lower layers of base fabrics are a set of weft threads.

Preferably, the technical conditions for drawing in the fly-through method in the above-mentioned weaving process are specifically, the consolidated ground structure is 1/1 plain weave, the pile warp adopts the 3/8W method, the tension on the machine reaches 200kg, and the speed of the cloth machine adopts 220 rpm , the width of the upper machine is 162-167cm, and the unhairing gear is adjusted to 66/16-32/62 at the same time, and the distance between the shear table and the shear ruler is adjusted to 4-45mm.

Preferably, in the above-mentioned warping process, the yarn is evenly wound on the tension roller for 3 turns, and the cylinder is loaded symmetrically. The yarn tension is uniform and the yarn path is clear.

Preferably, the above carding process adopts a combing gauge of 1mm-20mm, and the shearing gauge adopts a gauge of 1mm-37mm.

Preferably, the above-mentioned gluing and setting is to apply gluing on the side of the base fabric opposite to the fleece, and dry at 100-120°C.

Preferably, the length of the fleece between the above-mentioned upper and lower base fabrics is 1-36 mm.

Below in conjunction with the prior art of this field, technological process of the present invention is described in further detail again:

The first step is the winding process, which winds the skein yarn into a bobbin with moderate elasticity and uniform weight to prepare for the warping process; the second step enters the warping process, that is, the yarn on the bobbin is wound in parallel on the warp On the shaft, adjust the parameters to make the warp beam smooth and the yarn tension uniform, which is convenient for weaving; the third weaving process is the core process of this product manufacturing. Through parameter adjustment, the fluff and the upper and lower layers of base fabric are cross-woven at the same time , to the weaving mouth, the fluff is cut from the middle by the fleece knife on the loom, directly divided into upper and lower layers of fleece, and rolled onto the cloth roll. The weaving process is as follows: two continuous velvet warps that form the upper and lower base fabrics alternately extend into the two layers of base fabrics, and pass between the weft yarns of the two layers of base fabrics along the ground warp direction of the two layers of base fabrics respectively. After passing through three weft yarns, at the corresponding position of the fourth weft yarn, the two suede warps are cross-transposed between the upper and lower base fabrics, and then extend into the two layers of base fabrics respectively to enter the next cycle; the fourth step The woven flannelette is then combed through the combing process. The principle of combing is to comb through and cut evenly. The twist of the yarn is broken up by combing to keep the suede full, and the floating hair on the suede is cut off to keep the suede smooth. Smooth; the fifth step is to apply glue and set the shape. The size of the combed flannelette is unstable, and the fluff is not strong enough. It is necessary to mix soft glue and hard glue and apply it on the base fabric to shape it, so that the base fabric is stiff and the fluff is guaranteed. Firmness.

Compared with the prior art, the nylon fleece produced by the process of the present invention has plump and elastic suede, fine and smooth fluff, and the color fastness to wear and washing can reach 4 to 5 grades; The direction is 0%, and the height of the fluff reaches 1-36mm. When the nylon flannelette manufactured by the process of the invention is used for roller brushing, the painted paint is uniform, fine and smooth, and can clearly show the original lines of the painted furniture.
