Embodiment 1

[0026] Such as figure 2 Shown, the present invention discloses a kind of negative pressure type compact spinning head lapping method, and this method is to adopt double top roller lapping method on the spinning machine that negative pressure type compact spinning is installed, promptly front top roller 3 and front roller 4. The jaws of the composition take up the spinning.

[0027] The specific steps of the above-mentioned double top roller lapping method are as follows:

[0028] (1) Extubation: use the middle finger of the left hand as the main finger, and the ring and little fingers as the auxiliary to hold the bobbin 5 and pull it out. The extubation should be light and fast;

[0029] (2) Finding the end: use the thumb and index finger of the right hand to pinch the end of the yarn to lead out the yarn, and find the position of the end of the yarn quickly;

[0030] (3) Yarn drawing: lead the yarn out from the bobbin, then take out the traveler 6 with the index finger of ...

Abstract

The invention relates to a negative pressure type compact spinning head-lapping method. The method comprises the step of adopting a double-leather-roller head lapping method on a negative pressure type compact spinner, namely lapping the head and spinning at a jaw formed by a front leather roller and a front roller, wherein the double-leather-roller head lapping method specifically comprises six steps of tube drawing, end finding, yarn guiding, tube insertion, guide wire twisting and head lapping; the length of the guided yarn is shortened as far as possible under the situation of not influencing tube insertion and yarn lifting. The negative pressure type compact spinning head-lapping method disclosed by the invention has the advantages as follows: the double-leather-roller head lapping method is adopted; the head is lapped at the front leather roller position; compared with the lapping length and the roughness of the single leather roller lapping, the lapping length and the roughness are more obvious; in the automatic winding procedure, the lap can be identified as a yarn fault to be cut off more easily, so that the nub faults formed by the lap can be reduced to the lowest extent, the slight nub faults of the resultant yarn can be obviously reduced, and the cloth cover quality can be improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a negative-pressure compact spinning lapping method. Background technique [0002] In the upgrading of the textile industry, new spinning technologies are constantly emerging, among which the negative pressure compact spinning technology is particularly prominent. It installs an accumulation area between the drafting and twisting effects of the ring spinning twisting triangle area. The airflow is used to gather the strands so that the width of the strands decreases and the density increases when the yarn is output. At the same time, the gathering roller is used to make it punch down along the surface of the front roller, basically eliminating the friction of the strands on the surface of the front roller. Surrounding the arc reduces the height of the twisting triangular area, thereby greatly reducing yarn hairiness and improving yarn strength. At present, this type of yarn is c...
