Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] The method for controlling the grammage of knitted fabrics by a setting machine according to the present invention includes the following steps: (1) The speed of the setting machine is 15 m / min;

[0016] (2) According to the grammage of the knitted fabric, calculate the longitudinal density PaH of the knitted fabric, and the PaH value ranges from 23.4 stitches / cm to 37.1 stitches / cm;

[0017] (3) Measure the longitudinal density PbJ of the incoming cloth before the first overfeed roller of the sizing machine, and the value range of the PbJ is 21.8 coils / cm to 33 coils / cm;

[0018] (4) Divide the vertical density PaH of the lower machine in the step (2) by the longitudinal density PbJ of the cloth in the step (3) to convert the rate of change, and the range of the rate of change is 98.2% to 121.7 %;

[0019] (5) The rate of change is divided by the co...

Abstract

The invention relates to the technical field of fabric gram weight methods, and particularly relates to a method for controlling the gram weight of a knitted fabric based on a setting machine. According to the method, the overfeeding value is known in advance to control the setting overfeeding amount according to the actual situations of a fabric, so that the production overfeeding value is reasonably controlled, and the gram weights of an unknown fabric and a known fabric can be stably controlled; and a textile worker can conveniently convert the setting technological parameters according to the off-loom gram weights of fabrics during operation. With the method, the fluctuation of the gram weight can be prevented and known in advance, and the method is economic and practical.

Description

technical field [0001] The invention relates to the technical field of fabric grammage methods, in particular to a method for controlling the grammage of knitted fabrics by a setting machine. Background technique [0002] When ordering knitted fabrics in an open width, the sizing width and the overfeeding amount determine the grammage of the sizing machine. Taking the spandex variety as an example, the purpose of pre-setting finishing is: on the one hand, it is to eliminate the internal stress of the undyed cloth, so that the quality indicators such as fabric width and square meter weight are controlled; Denaturation (shrinkage rate), correcting the distortion and wrinkling of fibers during the weaving process, eliminating the uneven internal pressure of the fabric during weaving processing, ensuring the smoothness of the fabric surface during dyeing, and preventing streaks, creases and chicken claw marks during the dyeing process Wait. In this way, the pre-setting process...
