Embodiment 1

[0034] The preparation method of polyester fiber with purification function comprises the following two parts:

[0035] 1) TiO 2 Preparation of intercalated graphene oxide functional particles:

[0036] Get 10g 800 order expanded graphite and 250g 98% sulfuric acid (H 2 SO 4 ), placed in a 5000mL container. In the ice-water bath, under the condition of 800 rev / min, mechanically stir to make it fully mixed, then slowly add 20g of potassium permanganate until complete reaction. The solution was moved to an oil bath at 40°C, and operated at 600 rpm for 60 minutes. Add 300mL deionized water, react at 95°C for 25min; continue to add 600mL deionized water, stir evenly, add 30g 30% hydrogen peroxide (H 2 o 2) aqueous solution, the solution gradually changed from brown-black to bright yellow. Add deionized water, centrifuge and disperse at 5000 rpm and then wash to neutral to obtain graphene oxide. Take the graphene oxide prepared above in a hydrothermal reaction kettle, and d...

Abstract

The invention discloses polyester fibers with a catalytic degradation function and a preparation method thereof. The method comprises the following steps: firstly preparing TiO2 intercalated graphene oxide particles; cutting functional particles into micro-nano powder with a strong ultraviolet lamp; keeping the powder suspending in a cavity through air flow, and horizontally feeding colored polyester filaments into the cavity; softening the polyester fibers by controlling the temperature in the cavity so as to effectively bond with the powder; and carrying out hot pressing on the polyester filaments bonded with the functional powder to firmly bond the powder and the polyester fibers. The prepared novel polyester fibers have excellent catalytic degradation performance for aldehydes, benzene and other organic matters in vehicles; and the method is simple and feasible, and the catalytic degradation performance of the fibers can be durable and stable.

Description

technical field [0001] The invention relates to the field of functional fiber materials, in particular to a polyester fiber with catalytic degradation function and a preparation method thereof. Background technique [0002] With the continuous growth of automobile consumption, the demand for automotive textile fabrics has also increased steadily. Among them, in addition to the comfort, beauty, economical and durable performance required by traditional textiles, textile materials for automotive interiors have higher requirements for safety and environmental protection such as antifouling, flame retardant, antistatic, and UV protection. [0003] At present, people pay more attention to the environment inside the car. In China, the concentration of organic matter in the air in the car is implemented in accordance with the national standard GB / T27630-2011, and the domestic air organic matter concentration in passenger cars is about to implement mandatory standards. The specific...
