Problems solved by technology

The current conventional cold pad batch process takes 24 hours, which takes a long time. The whiteness, capillary effect, and strength of the product are easily affected by other factors and are unstable, and it still requires a short-term steaming high-temperature hot-alkali treatment process to achieve The required pre-processing effect and high energy consumption
Moreover, the quality of semi-finished products processed by the cold pad batch process is not high, the size and impurities can not be removed completely, and the gross effect is low, which greatly affects the quality of the subsequent dyeing and finishing process. Lack of serialization, specialization, standardization and unified test standards, corresponding additives cannot meet the development requirements of cold pad batch process

Abstract

The invention discloses a non-steaming cold pad-batch process of all-cotton or polyester-cotton fabric. The non-steaming cold pad-batch process includes the steps of firstly, padding the all-cotton or polyester-cotton fabric in desizing, refining and bleaching-bathing liquid which is aqueous solution of alkaline agents, additives, Wantefu PLA (polylactic acid) and 100% hydrogen peroxide; secondly, using a rolling machine to roll the fabric padded in the step 1, and batching up after wrapping; and thirdly, washing and drying the fabric batched in the step 2. The non-steaming cold pad-batch process provides moderate conditions, production time is shortened evidently, fabric damage is reduced, energy consumption is lowered, efficiency is improved, treatment of printing and dyeing wastewater is facilitated, and the treated fabric is better than that treated by the traditional cold batch process in terms of impurity removal, wettability and whiteness.

Description

technical field [0001] The invention relates to a non-steaming cold pad-batch process for cotton or polyester-cotton fabrics, belonging to the technical field of pretreatment of industrial fabrics in printing and dyeing. Background technique [0002] The pre-treatment process of printing and dyeing enterprises is a key process with high energy consumption, and its energy consumption and water consumption account for about 70% of the total energy consumption of the entire fabric processing. With the continuous increase of energy consumption and usage costs, printing and dyeing enterprises are looking for energy-saving processes to reduce energy consumption, and many enterprises are actively adopting energy-saving cold pad-batch pre-treatment processes. [0003] The traditional cold pad batch process is divided into three stages: the first stage, cold batch for 24 hours, mainly completes the swelling and oxidation reaction of impurities; the second stage, high temperature hot ...
