Embodiment 1

[0042] This embodiment provides a method for estimating the production capacity of single-sided plain weave fabrics produced by a circular weft knitting machine according to the present invention.

[0043] Include the following steps:

[0044] Fabrics are produced using circular weft knitting machines at specific machine speeds;

[0045] Measure and record the width and grammage of the fabric;

[0046] Measure and record the longitudinal density of the fabric;

[0047] Calculate and adopt described weft knitting circular machine to estimate the one-day production capacity of described fabric production according to following formula:

[0048]

[0049] in,

[0050] A 产 The estimated production capacity of fabrics produced by the weft knitting circular machine in one day, unit: kg;

[0051] F is the number of knitting systems that participate in weaving when the weft knitting machine produces the fabric;

[0052] W is the width of the fabric, unit: cm;

[0053] G is th...

Embodiment 2

[0061] The difference from Example 1 is that this example provides a method for estimating the production capacity of a weft knitting circular machine for producing double-sided plain weave + mesh fabrics.

[0062] This process is double-sided jacquard mesh fabric, the parameters are: model 20"14G8F, width 137cm, weight 330g / m 2 , the machine speed is 20r / min, the longitudinal density is 13.3 needles / cm, and the cloth surface is 2 lines and 1 line, that is, n=2, so the formula is calculated as follows:

[0063]A=24×60×8×137×330×20 / (2×10 7 ×13.3)=39.16 (kg / day).

[0064] In summary, this type of double-sided jacquard mesh fabric has a theoretical production capacity of 39.16kg / day, while the actual production capacity is 40kg / day, and the error between the calculated theoretical production capacity and the calculated theoretical production capacity data is 2.16%.

Embodiment 3

[0066] Different from Embodiments 1 and 2, this embodiment provides an estimate of the production of weft-knitted ordinary sandwiches by a weft-knitting circular machine.

[0067] This process is Sandwich Minari, the parameters are: model 34"24G72F, width 147.32cm, weight 277g / m 2 , the machine speed is 15r / min, the longitudinal density is 26 needles / cm, and the cloth surface is 3 lines and 1 line, that is, n=3, so it is substituted into the formula:

[0068] A=24×60×72×147.32×277×15 / (3×10 7 ×26)=81.36 (kg / day).

[0069] In summary, this type of double-sided jacquard mesh fabric has a theoretical production capacity of 80kg / day, while the actual production capacity is 81.36kg / day, and the error between the theoretical production capacity and the calculated theoretical production capacity data is 1.67%.

Abstract

The invention belongs to the technical field of knitting production, and particularly relates to a method for estimating the productivity of a circular weft knitting machine. The method comprises the following steps: producing a fabric by adopting the circular weft knitting machine with a preset number of paths according to a specific machine rotating speed; measuring and recording the breadth and gram weight of the fabric; measuring and recording the longitudinal density of the fabric; calculating the one-day productivity of fabric production estimated by adopting the circular weft knitting machine according to the following formula: A production is the estimated productivity of fabric production of the circular weft knitting machine in one day, and the unit is kg; f is the number of looping systems participating in knitting when the circular weft knitting machine produces the fabric; w is the breadth of the fabric, and the unit is cm; g is the gram weight of the fabric, and the unit is g/cm < 2 >; v is the machine rotating speed adopted when the weft knitting circular machine produces the fabric, and the unit is r/min; n is the number of looping systems required by each row on the fabric; m is the longitudinal density of the fabric, and the unit is needle/cm.

Description

technical field [0001] The invention belongs to the technical field of knitting production, and more specifically relates to a method for estimating the production capacity of a weft knitting circular machine which is simpler and suitable for popularization. Background technique [0002] The production capacity estimation of circular knitting machines plays a very important role in the production management arrangement and rational utilization of resources for textile manufacturers' existing gray fabric orders. Usually, accurately estimating the production capacity of a certain type of weft knitting circular knitting machine can achieve the goal of on-time quantitative delivery and minimizing the number of circular knitting machines started. However, for technical operators in the field, most of the current production capacity estimation methods of weft knitting circular machines need to consider the thickness of the yarn, the length of each coil, the specifications of the m...
