Problems solved by technology

[0003] In the multi-functional finishing of fabrics, step-by-step functional finishing is often used. Due to the poor compatibility between various finishing agents, although some functional finishing helps to improve some properties of the fabric, it also affects other properties. It has a negative impact, especially the very important wearing comfort, resulting in the loss of performance of functional fabrics

Abstract

The invention discloses a fabric multifunctional durable after-treatment method based on a deep-eutectic solvent. The fabric multifunctional durable after-treatment method comprises following steps: ahydrogen bond acceptor compound and a hydrogen bond donor compound capable of realizing light initiated polymerization are mixed to be uniform so as to prepare the deep-eutectic solvent, a metal oxide is added, and stirring dissolving is carried out so as to obtain a pre-finishing solution; before finishing, a photo-initiation polymerizer is added into the pre-finishing solution, and stirring dissolving is carried out so as to prepare a finishing solution; the finishing solution is adopted for finishing of fabric to be finished, the fabric treated through finishing is subjected to ultravioletirradiation, normal temperature water washing, and airing so as to obtain a durable multifunctional fabric. The durable multifunctional fabric is provided with corresponding functions, the fabric antibacterial performance, static resistance or electric conductivity, and crease resistance are achieved. The fabric multifunctional durable after-treatment method can be used for a plurality of kinds of fabric. The fabric multifunctional durable after-treatment method is green; no pollution is caused; less waste water is discharged; cost is low; operation is convenient; and the functional dyeing method is suitable for industrialized production.

Description

technical field [0001] The invention relates to a multifunctional and durable finishing method for fabrics based on a deep eutectic solvent, belonging to the technical field of functional finishing of textiles. Background technique [0002] The functional finishing of traditional textiles includes anti-wrinkle finishing, anti-ultraviolet, antibacterial, antistatic, etc., but most of the functional finishing methods either have a single effect, or have poor results, have obvious side effects, or are expensive, and some functional finishing methods even Harm to human body. For example, there are mainly amide-formaldehyde finishing agents and polycarboxylic acid finishing agents that can be used as anti-wrinkle finishing agents. Among them, amide-formaldehyde finishing agents will produce formaldehyde gas harmful to the human body and have relatively large side effects; Finishing agents are currently mainly BTCA and citric acid. The former has high cost and low water solubilit...
