Embodiment

[0026] Embodiment: a kind of production method of high-strength graphene-enhanced polyester staple fiber, comprises the following steps successively:

[0027] S1, prepare graphene masterbatch;

[0028] S2, melt mixing and granulating described graphene master batch and polyester fiber master batch to obtain mixed master batch;

[0029] S3, the mixed master batch is melted and blended to obtain the final graphene-enhanced polyester staple fiber,

[0030] Wherein, the material composition of the graphene master batch includes graphene powder, aluminum sulfate and ethylene glycol.

[0031] In this embodiment, the polyester fiber master batch adopts existing materials, and in the graphene master batch, the weight ratio of the graphene powder, aluminum sulfate and ethylene glycol is 5:3:2. for mixing and granulation.

[0032] In step S1, the graphene master batch adopts a three-stage zone heating method for heating extrusion and granulation, and the heating temperature is 210-24...

Abstract

The invention belongs to the technical field of fiber structures, and in particular relates to a method for producing high-strength graphene-reinforced polyester staple fibers. The invention achieves the effect of effective production of graphene-enhanced polyester staple fibers by first melting and granulating and then melting and blending the graphene master batch of a specific component and the common polyester fiber master batch. The invention has the advantages of simple and effective production method of graphene-enhanced polyester short fibers, high strength and good wear resistance of graphene-enhanced polyester short fibers, and good combined cooling effect of composite coolers in the production process. The reinforced polyester staple fiber has the advantages of moderate cooling speed, uniform cooling range, and simple and convenient cutting action after cooling.

Description

technical field [0001] The invention belongs to the technical field of fiber structures, and in particular relates to a method for producing high-strength graphene-reinforced polyester staple fibers. Background technique [0002] Polyester staple fiber, also known as polyester staple fiber, has the advantages of good water absorption, but also has the disadvantage of relatively poor strength. Therefore, there is an urgent need for a reinforced polyester staple fiber compounded with other fibers in the market. Structural strength of polyester staple fibers. [0003] The patent publication number is CN 110453309A, and the Chinese invention patent whose publication date is 2019.11.15 discloses a graphene-reinforced antistatic and antibacterial composite fiber, including an inner layer and an outer layer; the outer layer is wrapped around the outer periphery of the inner layer, And the cross-sectional profile of the outer layer is circular; the ratio of the cross-sectional area...
