Abstract

This study gives an achievable approach for reusing/repurposing of colored cellulosic textile waste to improve fabric coloration sustainability. Considering this aim, the usage of colored 100% cotton denim fabric waste that have been mechanically ground into micron-sized particles was proposed as a pigment in commercial screen printing pastes for cotton fabrics. After being ground at 800 rpm in various durations (2–8 min), fibrous cellulosic waste particles were included in printing pastes, then the prepared pastes were screen-printed onto cotton fabrics to observe the impacts of the grinding time on the fabrics' chemical, microscopic visual, tactile comfort, and mechanical properties. Changes in chemical structure of textile waste, before and after grinding, and screen-printed fabrics were evaluated by using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopies. The printing quality and performance of screen-printed fabrics were searched by means of tensile strength, abrasion resistance, fastness against washing/rubbing, color grade, surface hydrophilicity, air permeability, and handle properties. Scanning electron microscopy (SEM) evaluated the waste particles' dispersion quality on printed fabrics. The results indicated that grinding duration significantly influenced the color and comfort characteristics of the screen-printed fabrics. The WP-4 sample, with a 4-min grinding duration, demonstrated optimal performance by means of color strength and uniform particle distribution.

有色纤维素纺织废料生态染色升级利用途径探索：废料研磨时间效应

本研究提供了一种可实现的方法来再利用/重新利用有色纤维纺织废料，以提高织物的可持续性。考虑到这一目标，建议使用已机械研磨成微米大小颗粒的彩色100%棉牛仔布废料作为棉织物丝网印刷浆料的颜料。将纤维性纤维素废颗粒以800转/分（rpm）不同时间（2-8 min）研磨后加入印花浆料中，将制备好的浆料丝印到棉织物上，观察研磨时间对织物化学、显微视觉、触觉舒适性和力学性能的影响。利用x射线衍射（XRD）和傅里叶变换红外光谱（FTIR）对纺织废料、研磨前后和丝网印花织物的化学结构变化进行了研究。从拉伸强度、耐磨性、耐洗/摩擦牢度、颜色等级、表面亲水性、透气性和手感等方面考察丝网印花织物的印花质量和性能。扫描电子显微镜（SEM）评价了废颗粒在印花织物上的分散质量。结果表明，磨磨时间对丝印织物的颜色和舒适性有显著影响。研磨时间为4 min的WP-4样品在颜色强度和颗粒分布均匀方面表现最佳。图形抽象

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
