A method for producing a super-filament fluff fabric, comprising the steps of:

step one, with the rotation of the upper dial 1, the silk thread of the silk thread cylinder is hooked and pulled by each upper knitting needle 2;

step two, along with the rotation of the lower dial 3, the lower knitting needle 4 enters a rising area a and rises upwards under the driving of a triangle 5; with the rotation of the lower dial 3, the lower knitting needle 4 enters the thread hooking area b, and the lower knitting needle 4 hooks the thread of the upper knitting needle 2;

step three, along with the rotation of the lower dial 3, the lower knitting needle 4 hooked with the silk thread enters a descending area c and descends downwards under the driving of a triangle 5; with the rotation of the upper dial 1 and the lower dial 3, an upper knitting needle 2 and a lower knitting needle 4 which hook a section of silk thread respectively enter the upper side and the lower side of the wire pressing disc 61, the middle part of the section of silk thread is propped by the thin disc 611 of the wire pressing disc 61 and is bent inwards, and compared with the silk thread which is directly pulled by the lower knitting needle 4 and is in a linear state, the silk thread is bent, so that the length is longer and has a section of pre-pulling length; the edge of the thin disc 611 is arc-shaped, so that the length of the pre-drawn silk thread is gradually increased in the first half of the time when the silk thread is supported by the thin disc 611, because the lower knitting needles 4 are densely distributed, the lower knitting needles 4 hooking the silk thread at the rear side are gradually increased while the lower dial 3 rotates, and because the wire pressing disc 61 is positioned at the position of the descending area c close to one side of the wire hooking area b, no other lower knitting needles 4 hook or only one or two lower knitting needles 4 hook at the rear side of the lower knitting needle 4 hooking the silk thread in the stage, the resistance of the silk thread is smaller when the thin disc 611 supports the silk thread for pre-drawing, and the silk thread can relatively slide at the positions hooked by the upper knitting needles 2 and the lower knitting needles 4; namely, in the stage, the silk thread is pulled out for a certain length in advance under the condition of small resistance;

and step four, along with the rotation of the upper dial 1 and the lower dial 3, the silk thread is gradually separated from the position of the wire pressing disc 61, the lower knitting needle 4 is continuously lowered to pull down the silk thread, the edge of the thin type disc 611 is in a circular arc shape, therefore, in the later period of time when the silk thread is supported by the thin type disc 611, the length of the pre-drawn silk thread is gradually reduced, the length of the pre-drawn silk thread is supplied to the length of the silk thread required to be pulled by the lower knitting needle 4, at this time, although a large number of other lower knitting needles are arranged at the rear side of the lower knitting needle 4 to hook the silk thread, the resistance of the silk thread is large and difficult to slide, but because the pre-drawn silk thread is supplied, the lower knitting needle 4 can be continuously lowered to the lowest position so as not to break the silk thread.

And step five, the lower knitting needle 4 leaves the descending area c along with the rotation of the lower dial 3, and a section of long yarn is arranged between the upper knitting needle 2 and the lower knitting needle 4.

The vertical adjusting block 622 and the horizontal adjusting block 623 of the base 62 can adjust the upper and lower positions and the inner and outer positions of the wire pressing disc 61, namely adjust the length of a pre-drawn wire and be adaptively matched with the positions of the upper knitting needle 2 and the lower knitting needle 4; the rotatable design of the wire pressing disc 61 enables the wire to drive the thin disc 611 to rotate when the wire moves transversely, so that the thin disc 611 is prevented from cutting the wire.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
