Embodiment 1

[0041] A kind of self-cleaning polyester fiber for bedding filling, comprising the polyester fiber of the skin-core structure and titanium dioxide nanoparticles with a particle diameter of about 60nm loaded in the skin layer of the skin-core structure, the skin layer of the skin-core structure is A low-melting polyester with a melting point of 110°C and a thickness of about 100 nm. The core layer of the skin-core structure is polyethylene terephthalate (PET); the titanium dioxide nanoparticles form protrusions on the surface of the skin layer, so The protrusions endow the surface of the cortex with superhydrophobic properties. The self-cleaning polyester fiber for bedding filling is prepared through the following steps:

[0042] S1. Melt blending cellulose acetate butyrate and low-melting point polyester with a mass ratio of 8:1 as the cortex spinning raw material, and conventional polyester melt blending as the core spinning raw material;

[0043] S2. Putting the skin layer ...

Embodiment 2～8

[0051] Compared with Example 1, the self-cleaning polyester fiber for bedding provided in Examples 2-8 is different in that TiO 2 Particle size, skin thickness, cellulose acetate butyrate (m 1 ) and low melting point polyester (m 2 ) mass ratio and cortex spinning raw material (m 3 ) and core spinning material (m 4 ) quality ratio as shown in Table 1, others are basically the same as in Example 1, and will not be repeated here.

[0052] In the following examples, the loading amount of titanium dioxide nanoparticles is calculated according to the thickness of the polyester fiber skin layer and the particle size of titanium dioxide, so as to reasonably control the speed, flow rate and bombardment time of the high-speed titanium dioxide nanoparticle flow.

Abstract

The invention provides a self-cleaning polyester fiber for filling bed products and a preparation method thereof. First, low-melting point polyester fiber and conventional polyester fiber are selected for composite spinning to obtain a skin-core structure polyester fiber with a thickness of 50-500nm; In the molten state of the fiber, a high-speed titanium dioxide nanoparticle flow is used to bombard the surface of the polyester fiber with a skin-core structure. The titanium dioxide nanoparticle is coated in the low-melting polyester fiber with a skin layer, and the load fastness is significantly improved. By controlling the flow rate and bombardment time of the titanium dioxide nanoparticle flow, the titanium dioxide nanoparticles form protrusions or depressions on the surface of the skin layer. This structure endows the surface of the skin layer with superhydrophobic properties; in addition, the photocatalytic effect of titanium dioxide can degrade organic stains, thus giving polyester Fiber double self-cleaning function.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and in particular relates to a self-cleaning polyester fiber for bedding filling and a preparation method thereof. Background technique [0002] Polyester fiber is widely used in the field of textiles due to its many advantages, and has become the most widely used and most consumed fiber raw material in the field of textiles. At present, polyester fiber is widely used in clothing fillings and other fields, and its application in the field of bedding is also quite extensive, such as fillings for quilts, mattresses, pillows, blankets and throw pillows. After being used for a long time, the bedding stuffing will inevitably be soiled by stains and other substances, creating favorable conditions for the growth of bacteria, and the stuffing is not easy to clean, and frequent cleaning will reduce the service life and wearing comfort of the bedding. Therefore, when polyester fiber i...
