Problems solved by technology

The disadvantage of this process is that it increases the complexity of the process, and increases the cost of planning and the exhaust gas generated during the booking, causing pollution to the atmosphere. At the same time, the strength of the gray cloth decreases, and the width of the door is not necessarily small, which may lead to too large a width of the finished product. , light weight
[0005] Therefore, the above two processes are not easy to use, and a better dyeing process is needed to solve the problem

Abstract

The invention relates to the field of dyeing and finishing and discloses a method for eliminating chinlon rayon spandex Ponte-de-roma fabric low-bath ratio airflow dyeing corrugation. The method comprises steps of (1) preshrinking of gray fabric width, (2) setting prestored operation parameters of an airflow dyeing machine, (3) flattening a piping joint before cloth feeding, (4) conducting pre-processing for the gray fabric, (5) conducting rayon reactive dyeing, (6) conducting chinlon acid dyeing, (7) fixing color, namely adding dye-fixing agent, (8) dehydrating the fabric and (9) conducting post-treatment, drying and fixing. The method changes a traditional dyeing technology with great bath ratio and gray fabric fixation and selects an airflow dyeing machine with low bath ratio for dyeing, so energy-saving technology with avoidance of corrugation of a chinlon rayon spandex Ponte-de-roma fabric can be achieved; through concrete technology adjustments and improvements, the gray fabric can stay at an operation state with low tension and high expansion; and an arrangement state of the gray fabric can be continuously changed in a tank body, so corrugation production can be prevented.

Description

technical field [0001] The invention relates to the field of dyeing and finishing, in particular to a method for eliminating wrinkles of nylon, rayon, spandex and roman cloth with low liquor ratio air-flow dyeing. Background technique [0002] At present, with the increasing number of orders for nylon rayon spandex Roman cloth, the following two processes are generally used for some large weight, tight nylon spandex Roman cloth that is easy to wrinkle during the dyeing process: [0003] One is dyeing in a large bath ratio overflow tank. In this dyeing machine, the dyeing bath ratio should be more than 1:15, the speed of the cloth lifting wheel should be accelerated, and the cooling speed should be slowed down at the same time. After cooling down, the temperature before washing should be lower. That is, 1-1.5 degrees per minute drops to 80 degrees, then drops 3 degrees per minute to 60 degrees, first washes with hot water at 40 degrees, then drains, and then washes in cold wa...
