Example Embodiment

[0018] Example 1:

[0019] The graphene polyester antibacterial composite fiber provided by this embodiment is composed of nylon fiber as the core thread and coated with polyester fiber. The nylon fiber includes 95 parts of nylon and 5 parts of modifier by weight. The modifier includes 70 parts of graphene, 10 parts of basalt, and 2 parts of polytetrafluoroethylene in parts by weight;

[0020] The polyester fiber includes 93 parts of polyester and 7 parts of antibacterial agent in parts by weight, and the antibacterial agent includes 40 parts of polyhexamethyleneguanidine hydrochloride, 20 parts of chitosan, and 10 parts of carboxymethyl cellulose in parts by weight. Sodium and 5 parts of zinc sulfide.

[0021] The invention also discloses a preparation method of the graphene polyester antibacterial composite fiber, which comprises the following steps:

[0022] The first step: prepare the modifier, mix 70 parts of graphene, 10 parts of basalt, and 2 parts of polytetrafluoroethylene a...

Example Embodiment

[0028] Example 2:

[0029] The graphene polyester antibacterial composite fiber provided in this embodiment has the same raw materials and preparation method as in Example 1. The main difference is that the nylon fiber includes 98 parts by weight of nylon and 2 parts of modifier. The agent includes 80 parts of graphene, 18 parts of basalt, and 5 parts of polytetrafluoroethylene by weight.

[0030] The graphene polyester antibacterial composite fiber obtained in this example was subjected to antibacterial testing, and the composite fiber had an inhibition rate of 99.98% against Escherichia coli and Staphylococcus aureus.

Example Embodiment

[0031] Example 3:

[0032] The raw material and preparation method of the graphene polyester antibacterial composite fiber provided in this embodiment are roughly the same as those in Example 1. The main difference is that the polyester fiber includes 95 parts by weight of polyester and 5 parts of antibacterial agent. Parts by weight include 50 parts of polyhexamethyleneguanidine hydrochloride, 25 parts of chitosan, 15 parts of sodium carboxymethyl cellulose, and 10 parts of zinc sulfide.

[0033] The graphene polyester antibacterial composite fiber obtained in this example was subjected to antibacterial testing, and the composite fiber has an inhibition rate of 99.96% against Escherichia coli and Staphylococcus aureus.

Abstract

The invention discloses graphene terylene antibacterial composite fiber which takes polyamide fiber as a center yearn and is coated with polyester fiber, the polyamide fiber comprises the components,by weight, of 95-98 parts of chinlon and 2-5 parts of modifying agent, the modifying agent comprises the components, by weight, of 70-80 parts of graphene, 10-18 parts of basalt and 2-5 parts of polytetrafluoroethylene; the polyester fiber comprises the components, by weight, of 93-95 parts of terylene and 5-7 parts of antibacterial agent, and the antibacterial agent comprises the components, by weight, of 40-50 parts of polyhexamethyleneguanidine chloride, 20-50 parts of chitosan, 10-15 parts of sodium carboxymethylcellulose and 5-10 parts of zinc sulfide. According to the prepared graphene terylene antibacterial composite fiber, the polyamide fiber and the polyester fiber complement mutually by the technical effects, the advantages are highlighted, the disadvantages are improved, and thefinally prepared composite fiber is comfortable in hand feeling and high in strength and has certain antibacterial property.

Description

technical field [0001] The invention relates to a composite fiber, in particular to a graphene polyester antibacterial composite fiber. Background technique [0002] Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is its good wrinkle resistance and shape retention. Therefore, it is suitable for outdoor products such as outerwear, various bags and tents. The strength of polyester fiber is nearly 1 times stronger than cotton and 3 times stronger than wool, so polyester fabric is strong and durable. Polyester fiber can be used at 70-170°C, and it has the best heat resistance and thermal stability among synthetic fibers. The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds that of other fibers. The fabric does not wrinkle and has good shape retention. Polyester has low water absorption and moisture regain and good insulation performance, but due to low water absorption, the static...
