Open-width continuous washing system

Abstract

The invention belongs to the technical field of production and application of fabric and particularly discloses an open-width continuous washing system. The system comprises a cloth feeding assembly, a water washing machine, a first wash water box, a second wash water box, a first single-drum wash water box, a second single-drum wash water box and a cloth discharging assembly. The open-width continuous washing system has the beneficial effects as follows: by means of the system, continuous washing can be realized for fabric printing and dyeing, washing processing technique requirements of high-grade knitted fabric are met, the defect that the conventional knitted fabric washing processing process is required to be performed in batches and in different vats is overcome, the production efficiency is improved, and the production time is saved; besides, consumption of water, electricity and steam is reduced, the purposes of high efficiency, low energy consumption, low emission and environmental protection are achieved, and water fastness, dry/wet rub fastness and six-fiber test performance are improved to 0.5-1 level; practice proves that compared with a conventional dyeing vat process, the system has the advantages that during continuous washing on the basis of the yield of 15 tons every day, about 28 tons of water is saved for each ton of cloth by use of the equipment, about 126,000 tons of water can be saved every year, and the water saving and emission reduction effects are very remarkable.

Description

technical field [0001] The invention belongs to the technical field of fabric production and application, and in particular relates to a continuous open-width washing system. Background technique [0002] Environmental protection and clean production are important themes of future industrial development. The concept of printing and dyeing technology development has shifted to eco-environmental protection, and clean production has become crucial. At present, the boiled cloth processing of domestic cotton knitted varieties is mainly based on rope-shaped and overflow machines. This traditional, intermittent processing method requires repeated water injection and drainage for each process, and multiple starts and stops. The consumption of electricity and steam is large, the time is long and the efficiency is low. Single-sided and ammonia-woven fabrics are easy to wrinkle. Some types of fabrics will have napping damage and burst holes, which seriously affect the quality of produc...

At present, the boiled cloth processing of domestic cotton knitted varieties is mainly based on rope-shaped and overflow machines. This traditional, intermittent processing method requires repeated water injection and drainage for each process, and multiple starts and stops. The consumption of electricity and steam is large, the time is long and the efficiency is low. Single-sided and ammonia-woven fabrics are easy to wrinkle. Some types of fabrics will have napping damage and burst holes, which seriously affect the quality of products. This is a very serious problem encountered by many manufacturers. Headaches with intractable problems

[0003] In the traditional dyeing of knitted fabrics, most dyeing factories use pre-treatment in the dye vat, which has many problems: (1) the oil agent in the weaving process has the risk of demulsification in the dye vat; (3) The fabric is easy to scratch; (4) The oil on the surface of the fabric is unevenly dispersed, and it is easy to form yellow and white unevenness; (5) The fabric is prone to explosion holes; (6) Pretreatment and dyeing are all in the dyeing tank A large amount of sewage is treated
