Embodiment 1

[0033] The preparation method of polyester fiber with purification function includes the following two parts:

[0034] 1)TiO 2 Preparation of intercalated graphene oxide particles:

[0035] Take 10g 800 mesh expanded graphite and 250g 98% sulfuric acid (H 2 SO 4 ), placed in a 5000mL container. In an ice-water bath, under the condition of 800 revolutions per minute, mechanically stir, make it fully mixed, and then slowly add 20 g of potassium permanganate to complete the 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℃ for 25min; continue to add 600mL deionized water, stir evenly, add 30g 30% hydrogen peroxide (H 2 O 2 ) Aqueous solution, the solution gradually changes from brown-black to bright yellow. Add deionized water, centrifuge and disperse at 5000 rpm, and wash to neutrality to obtain graphene oxide. Take the above-prepared graphene oxide in a hydrothermal reactor, seal it under 140℃ a...

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 preparation method of polyester fiber with catalytic degradation function. 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, economy and durability required by traditional textiles, textile materials for automotive interiors have higher requirements in terms of anti-fouling, flame-retardant, anti-static, anti-ultraviolet and other safety and environmental protection. [0003] At present, people pay more attention to the environment in the car. The national standard GB / T27630-2011 for the concentration of organic matter in the air in the car is implemented. The mandatory standard for the concentration of organic matter in the air in the passenger car will soon be implemented. The specific requirements are as follows: [0004] ...
