CN103351585B - Antibacterial and antistatic polyester resin slice - Google Patents

Abstract

The invention relates to an antibacterial and antistatic polyester resin slice. The raw material formula of the antibacterial and antistatic polyester resin slice is as follows: 75 to 85 parts of PET slices, 5 to 15 parts of antibacterial additives, and 0.5 to 15 parts of antistatic additives. 5 parts, 5~10 parts of plasticizer, wherein the molecular weight of the PET chips is 25000~50000, and the plasticizer is dibutyl phthalate, diisopropyl phthalate, phthalate One of dipyl formate. Due to the application of the above-mentioned technical scheme, the present invention has the following advantages: antibacterial additives and antistatic additives are added to the polyester resin chip raw materials at the same time, so that the polyester resin chip has antibacterial and antistatic properties at the same time, and the textiles prepared by using the polyester resin chip are endowed with permanent Excellent antibacterial and antistatic properties can meet people's increasing requirements for textiles.

Description

A kind of antibacterial and antistatic polyester resin chip

technical field

The invention belongs to the field of spinning raw materials, and in particular relates to an antibacterial and antistatic polyester resin chip.

Background technique

With the continuous improvement of living standards, people's requirements for textile products are also constantly improving. Textiles with special properties such as anti-ultraviolet, antibacterial, odor absorption, antistatic, and infrared warmth are attracting more and more people's attention.

In order to make textiles have the above properties, engineers have designed two methods: one is to add various nanomaterials to polyester melt, and then spin to form fibers, and then weave the fibers into cloth; The fabric is immersed in the solution containing the nanoparticle precursor, and the nanoparticle is attached to the fabric by adjusting the pH value and temperature of the solution. Among them, the textiles prepared by the latter method will lose their special properties due to the gradual loss of nanoparticles during use, while the former method can endow textiles with permanent special properties, so it is widely used.

For example, the Chinese invention patent application publication number CN102702692A discloses an antibacterial porous polyester chip and its method for preparing and processing POY filaments and DTY filaments, and the prepared PET polyester chip has good antibacterial effect. However, the filaments spun from the PET polyester chips will inevitably accumulate static electricity during use, which is not conducive to human health.

Contents of the invention

The object of the present invention is to provide a polyester resin chip capable of antibacterial and antistatic in order to overcome the deficiencies of the prior art.

In order to achieve the above object, the technical solution adopted in the present invention is: a kind of antibacterial antistatic polyester resin slice, in parts by weight, the raw material formula of described antibacterial antistatic polyester resin slice is as follows: PET slice 75～85 parts, antibacterial 5-15 parts of additives, 0.5-5 parts of antistatic additives, 5-10 parts of plasticizers, wherein the molecular weight of the PET chips is 25000-50000, and the plasticizers are dibutyl phthalate, ortho One of diisopropyl phthalate and dipentyl phthalate.

Optimally, the antibacterial additive is a powder with silver nanoparticles loaded on the surface of silica as a carrier.

Further, the mass ratio of silver to silicon dioxide is 1:1-5.

Optimally, the antistatic additive is nano titanium dioxide.

Further, the particle size of the nano-titanium dioxide is 50-200nm.

Due to the application of the above-mentioned technical scheme, the present invention has the following advantages compared with the prior art: adding antibacterial additives and antistatic additives to the raw materials of polyester resin slices simultaneously, so that polyester resin slices have antibacterial and antistatic properties at the same time, so using the polyester resin The textiles prepared by slicing are endowed with permanent antibacterial and antistatic properties, meeting people's increasing requirements for textiles.
