Problems solved by technology

Among the unqualified products, it is mainly the "safety requirements and quality" required by the national standard testing, and quality problems such as carcinogens, formaldehyde, pH, dry / wet rubbing fastness, and light fastness are detected. Therefore, actively develop and produce green, environmentally friendly The processing and production of school uniforms to ensure qualified products is the general trend of the industry. School uniforms are polyester-cotton fabrics. The traditional production process is pre-treatment→dyeing (dyeing and washing)→cleaning (multiple washings)→dyeing cotton→soaping (multiple times) Washing)→color fixing→softening (non-hydrophilic soft oil)→dehydration→wet dissection→drying→settling→testing→scanning→packaging / warehousing, the traditional process uses an increase in the use of dyeing and chemical additives , Increase the number of cleaning times, increase the bleaching and dyeing bath ratio and other cost inputs and measures, but the effect obtained is not ideal, it is still difficult to ensure the standard requirements of product quality, but it increases pollution and emissions, and increases a lot of energy consumption and production costs. To be further improved

Abstract

The invention discloses a school uniform fabric production technology. The technology comprises pretreatment, polyester dyeing, first reduction cleaning, drainage, hot washing, water washing, second reduction cleaning, hot washing, cotton dyeing, fixation, softening, scutching wool washing machine-based water washing, drying, setting, detection, final inspection, and packaging / warehousing. A low temperature scouring and bleaching agent TF-189 is used, a treatment temperature is reduced by 25 DEG C from a high temperature 110 DEG C to a low temperature of 85 DEG C, a hot washing process is avoided, after treatment, whiteness, hair effects and dyeing effects are similar to those of the traditional oxygen bleaching process, energy consumption is reduced, polyester dying and reduction cleaning processes are combined because of the complementarity, the traditional sodium hydrosulfite alkaline reduction cleaning method is replaced by the technology provided by the invention, sodium hydrosulfite-caused pollution and damage are reduced, environmental friendliness is realized and energy saving and emission reduction effects are obtained.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a production process for school uniform fabrics. Background technique [0002] School uniforms originated in Europe, the main performance is: to display and cultivate students' team spirit, enhance the collective sense of honor, quality education and the spiritual outlook of primary and secondary school students, and it is also the exclusive symbol of youth and children's vitality, high spirits and vitality. my country has had school uniforms since the Revolution of 1911. After several historical changes, from single to diverse, from appearance and style changes to internal quality requirements, the development of the school uniform industry is in the ascendant. In recent years, the space and market of the school uniform textile industry have formed an advantageous industrial group. [0003] According to the latest census data, as of the end of 2015, the population of mainland China reached 1...
