Abstract

The invention discloses a rare-earth luminescent spun-bonded non-woven fabric and a production method and composition thereof. The rare-earth luminescent spun-bonded non-woven fabric comprises, by weight, 90-110 parts of slices, 3-30 parts of SrAl2O4:Eu2+, Dy3+, 0.01-0.03 part of glycerin mono-fatty acid ester, 0.02-0.04 part of phosphite ester, 0.01-0.05 part of 2-hydroxide radical-4-octyl oxygen radical hydroxyl diphenyl ketone, 0.03-0.04 part of polyving akohol and 0.1-0.5 part of methylcellulose. The production method comprises the steps that firstly, the SrAl2O4:Eu2+, Dy3+, the glycerin mono-fatty acid ester, the phosphite ester, the 2-hydroxide radical-4-octyl oxygen radical hydroxyl diphenyl ketone, the polyving akohol and the methylcellulose are added to the dried slices to be fused, and a fused solution is obtained; secondly, the fused solution is added to a screw extruder to be extruded out in a fusion state, and a plurality of continuous filaments are produced through a spinneret plate and are drafted and collected to a lapping machine; lastly, the rare-earth luminescent spun-bonded non-woven fabric is produced by means of hot-pressing through a hot-press roller. A rare-earth aluminate luminescent material is good in chemical stability and heat stability, low in production cost, free of radioactivity and safe and harmless to the human body.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabric manufacturing, and relates to a rare earth luminescent spunbonded nonwoven fabric, a manufacturing method and a composition thereof. Background technique [0002] Spunbond nonwovens are also called spunbond nonwovens. Spunbond nonwovens are polymers that are extruded and stretched to form continuous filaments. Bonding, chemical bonding or mechanical reinforcement methods to make the web into a non-woven fabric. [0003] In the existing technology, there are long afterglow luminous cloth and luminous cloth. The luminous fabric is mainly made of chemical fiber fabrics, polyester, silk, cotton, hemp, etc. Fading, the nonwoven fabric is visible at night and can be widely used in construction, textile, automobile, hygiene industry and other fields. [0004] Existing luminous cloths and luminous cloths have poor chemical stability and thermal stability, are radioactive, and are harmful to huma...
