A process for thickening hand feeling of polyester printed fabric

Abstract

The invention relates to the technical field of textile production, in particular to a process for thickening the hand of polyester printed fabrics, comprising the following steps: S1, weaving: weaving into grey fabrics through a double-needle bed Raschel knitting machine; S2, presetting: The grey cloth in S1 is sent to the drying room through the conveyor belt for pre-forming, the vehicle speed is 20-25m / min, the temperature is 200°C, the air speed in the drying room is 1200-1500r / min, and the time is 100-120s; S3, dyeing: Pre-forming in S2 The finished grey fabric is transported into the atomizing nozzle of the high-temperature and high-pressure airflow dyeing machine, and the following dyeing auxiliaries are introduced into the dye liquor tube in the airflow dyeing machine: disperse dyes, leveling agents, and the dyeing process is at a temperature of 120-130°C, The holding time is 30-50min; it realizes the dyeing with the atomized dye solution twice before and after, so that the dyeing rate is good, the dyeing is uniform, and the dyeing property is improved. By continuously accelerating the high-speed airflow, the wound grey fabric can be fluffy and blown, which further improves the To ensure level dyeing performance, at the same time to ensure that the dyed grey fabric feels soft and thick.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a process for thickening hand feeling of polyester printed fabrics. Background technique [0002] In recent years, with the popularity of international casual clothing and the increasing demand for innovation in the textile market, the requirements for textiles have become higher and higher. However, the existing polyester fabrics have high strength, wear resistance and durability, bright colors and durable color. However, there are hard hand feel and poor dyeability, resulting in few colors, inexact printing, and difficult to control the dyeing fastness of the fabric, which affects the appearance and hand feel, and is difficult to meet the needs of the market. [0003] At present, the polyester printing process generally includes weaving, pre-setting, dyeing, drying, discharge printing and post-processing steps, and the success of dyeing is directly related to the fin...
