Method and system for optimal design and process control of heat setting process of elastic fabric

Abstract

The invention discloses a method and a system for optimal design and process control of a heat setting process of an elastic fabric. The method comprises the following steps of: a) establishing a heat setting process model of the elastic fabric according to relations among parameters of the elastic fabric, heat setting quality indexes and heat setting process parameters; and b1) acquiring the heat setting quality indexes by taking the parameters of the elastic fabric and the heat setting process parameters as initial conditions according to the heat setting process model; or b2) determining the heat setting process parameters by taking the parameters of the elastic fabric and the heat setting quality indexes of design requirements as initial conditions according to the heat setting process model, and selecting the optimal heat setting process parameter according to a preset determination rule, wherein the heat setting quality indexes at least comprise heat setting efficiency which is the ratio of breadth of a finished fabric to breadth during setting; the heat setting process parameters at least comprise heat setting time and a heat setting temperature; and the heat setting process model comprises a multivariate non-linear model for defining relations between the heat setting efficiency and the heat setting time as well as the heat setting temperature.

Description

technical field [0001] The present invention relates to a method and system for optimal design and process control of elastic fabric heat setting process, especially a method and system for predicting heat setting quality according to elastic fabric heat setting process model, determining optimal heat setting process parameters, and controlling heat setting process methods and systems. Background technique [0002] Heat setting is an important link in the production process of textile dyeing and finishing. Heat setting is the process of keeping the fabric at a certain size, heating it at a high temperature for a certain period of time, and then cooling it at an appropriate speed. The purpose of heat setting processing is to make the flatness, width, weight and moisture content of the fabric meet the user's requirements under heating. [0003] The quality indicators of elastic fabric heat setting mainly include door width, gram weight, shrinkage rate, etc. The process param...

Problems solved by technology

However, because it is a complex multivariate mathematical model to describe the relationship between heat setting process parameters and quality indicators, and there is currently a lack of research on the mechanism and model of elastic fabric heat setting process, there is no research on elastic fabric heat setting process parameters at home and abroad.
