Abstract

The invention relates to the technical field of non-woven fabrics, and discloses a damp-proof and mildew-proof after-finishing agent for non-woven fabrics as well as a preparation method and application thereof. The damp-proof and mildew-proof after-finishing agent comprises a calcined shell powder inner core and a modified hydroxyapatite shell, wherein the modified hydroxyapatite shell coats thecalcined shell powder inner core in a dotted manner, the modified hydroxyapatite is hydroxyapatite which is subjected to graft modification by isopropyl di (methacryloyl) isostearoyl titanate, and camphor tree essential oil is loaded in the calcined shell powder inner core. The damp-proof and mildew-proof after-finishing agent can slowly release camphor tree essential oil in a low-humidity environment and accelerate release of the camphor tree essential oil in a high-humidity environment, in this way, the damp-proof and mildew-proof after-finishing agent can meet the mildew-proof requirementsunder different humidities, meanwhile, excessive release of the camphor tree essential oil is avoided, long-acting mildew prevention is achieved, in addition, the damp-proof and mildew-proof after-finishing agent can be grafted to the non-woven fabric through an ultraviolet grafting reaction, and the application range of the damp-proof and mildew-proof after-finishing agent is very wide.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a moisture-proof and mildew-proof finishing agent for non-woven fabrics and a preparation method and application thereof. Background technique [0002] Non-woven fabrics are also called non-woven fabrics. The production process is usually to make fine fibers into a net, and then combine them through various treatments such as mechanical, bonding, heating, dissolving or chemical treatments. Compared with woven fabrics, non-woven fabrics have the following advantages: In terms of technological characteristics, in addition to retaining the pre-spinning processes such as textile opening and carding, non-woven fabrics almost completely omit the traditional textile spinning process. Drawing frame, roving, spun yarn, winding and other processes, as well as warping, sizing, and weaving in weaving, form fiber products with a very short process, high efficiency and automation, so...
