Method and device to adjust setting state of fabric for tendering setting machine

Abstract

The invention discloses a method and device to adjust setting state of fabric for a tendering setting machine. The tendering setting machine includes an oven, a central processing unit and an upper air pipe and lower air pipe arranged in the oven; a bottom plate of the upper air pipe is provided with a plurality of upper air nozzles; a top plate of the lower air pipe is provided with a plurality of lower air nozzles; fabric runs between the upper and lower air nozzles; a fabric cover detection device is arranged outside the oven; the central processing unit, based on weft deformation of the fabric detected by the fabric cover detection device, changes the angle between hot blast from upper and / or lower air nozzles and running direction of the fabric, thereby reducing or eliminating weft deformation of the fabric. The method and device enable weft deformation deviation during fabric setting to be greatly reduced, the fabric setting qualification rate is higher, the device is simple in structure, and the method is convenient to implement.

Description

technical field [0001] The invention relates to a method and a device for setting the shape of a tenter-setting woven fabric, in particular to a method and a device for adjusting the setting state of a tenter-setting woven fabric, and belongs to the technical field of textile dyeing and finishing technology and equipment. Background technique [0002] Stenter setting machine is a commonly used equipment for dyeing and finishing fabrics. Stenter heat setting of the fabric is to use the high temperature hot air in the oven of the setting machine to eliminate the internal stress of the fabric fiber during the stretching process, so that the shape of the fabric is fixed and shaped. The fabric after setting has good dimensional stability, hand feeling, color, Width, strength and appearance. [0003] During the tenter setting process, the fabric is usually dried with hot air, and the hot air is sprayed onto the fabric through the air nozzle to dry the fabric and complete the proc...

AI Technical Summary

Problems solved by technology

[0004] Fabrics, especially knitted fabrics, have the inherent properties of large extensibility and easy deformation, and the fabrics have certain plasticity characteristics at the setting temperature. The plane is vertical, and the forward moving airflow at a certain flow rate encounters the obstruction of the fabric, a part of the hot air passes through the fabric, and a part of the airflow diffuses to the periphery to form a pressure air curtain, which exerts pressure on the fabric, both of which make the weft yarn move forward with the fabric. The deformation of the weft yarn caused by the resistance will seriously affect the quality of the fabric setting, which will greatly affect the subsequent processing and sales of the fabric
