Abstract

The invention relates to a preparation method of a luminescent low-stretch yarn for inner decorating materials for an automobile. The prepared luminescent low-stretch yarn has a leather core structure shown in a figure 1. The yarn is prepared from the following components in percentage by mass: 65-40wt% of core layer, 25-35wt% of an intermediate layer and 10-35wt% of a leather layer, wherein the core layer is polyethylene terephthalate resin; the middle layer is polyester resin containing a strontium aluminate rear earth luminescent material, the content of the rear earth luminescent material is 20-45wt%, and the structural formula is Sr(0.99-0.95)Eu(0.01-0.05)Al2O4(Al(1-a-b)BbDya)2O3[a is 0.01-0.35 and b is 0.001-0.004]; the leather surface is polyolefin resin or polyester resin; the leather core structure is the luminescent low-stretch yarn, the afterglow intensity of the yarn which is stopped in activation in one minute is over 600mcd / m<2>, and the diameter of a single fiber is less than 60 microns. The rare earth luminescent fiber of a leather core compound structure prepared by the method is high in intensity, good in toughness and good in wear-resisting and wash-resisting performances, and can satisfy the application requirements of the inner decorating materials for the automobile.

Description

technical field [0001] The invention belongs to the technical field of functional textile fibers, and in particular relates to a preparation method of luminous low-elasticity yarn for automotive interior fabrics. technical background [0002] There are two types of luminous fibers: self-illuminating and energy-storing. Self-luminous fibers can continue to emit light without absorbing energy from the outside, but the luminescent materials used are radioactive, which greatly limits their application. The energy-storage luminous fiber needs to absorb energy from the outside first, such as sunlight, light, etc., and then the electrons in the luminescent material undergo electronic transitions to store the absorbed energy, and can continue to emit light in a dark environment, playing a warning and beautiful role. effect. Since the energy storage luminous fiber does not contain radioactive substances, it is safer to avoid harm to the human body. In recent years, it has developed ...
