Abstract

The invention discloses a calculation method of the yarn feeding amount a positive yarn feeding mode of a circular weft knitting machine. By calculating the yarn length of a certain number of knittingneedle knitting loop structures, a yarn storage wheel can change the yarn feeding amount according to the yarn length needed by knitting in the knitting process, it is ensured that the tension is constant when yarns enter a knitting area, the size difference between the same loops is reduced, patterns can be clearer, the cloth cover is flatter, and the quality and aesthetic degree of a fabric aregreatly improved.

Description

technical field [0001] The invention relates to a method for calculating the yarn feeding amount in a positive yarn feeding mode of a circular weft machine, belonging to the technical field of textile processing. Background technique [0002] The yarn feeding mechanism is an important device of the circular knitting machine. At present, most of the jacquard circular weft machines use passive yarn feeding, and the yarn is withdrawn from the creel and led to the weaving area by means of the tension generated by the loop forming parts on the yarn during weaving. Change the yarn feeding speed according to the different instantaneous yarn consumption, but the tension will fluctuate when the yarn enters the weaving area, which will cause a certain difference in the size of the coil and affect the smoothness of the cloth surface. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a calculation method for the ...
