Problems solved by technology

The commonly used anti-ultraviolet agents include silicon dioxide, zinc oxide, aluminum oxide, etc. Although the addition of these inorganic anti-ultraviolet agents can improve the anti-ultraviolet performance of non-woven fabrics, a higher amount of addition is required to achieve the ideal anti-ultraviolet rays. effect, but this will seriously affect the mechanical properties of non-woven fabrics
Moreover, these inorganic anti-ultraviolet agents have a short anti-ultraviolet life, especially after repeated washing, the anti-ultraviolet performance will be significantly reduced, so they cannot meet the initial anti-ultraviolet use requirements for non-woven fabrics.

Abstract

The invention relates to the technical field of processing of nonwoven spunlace and discloses a processing process of plant fiber nonwoven spunlace with a selective ultraviolet blocking function. Theprocess includes steps: (1) pulping; (2) filtering and decontaminating; (3) ultraviolet modification; (4) fiber net forming; (5) spunlacing; (6) drying; (7) microwave fixation; (8) packaging. The processing process of the plant fiber nonwoven spunlace has advantages that by adoption of cotton fibers as a raw material, extensive raw material source, cheapness, high process repeatability and exact control condition parameters are realized, and the prepared nonwoven spunlace has excellent ultraviolet-proof performance besides great mechanical properties.

Description

[0001] Technical field: [0002] The invention relates to the technical field of spunlace nonwoven fabric processing, in particular to a plant fiber spunlace nonwoven fabric processing technology for selectively blocking ultraviolet rays. [0003] Background technique: [0004] Spunlaced non-woven fabric is a fabric obtained by spraying high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The fiber raw materials of spunlace non-woven fabrics come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. [0005] Spunlace non-woven fabric has the characteristics of high strength, low fluff, high moisture absorption, good air permeability, soft hand feeling, and good drapability. Performance is poor. At present, the anti-ultraviolet performanc...
