preparation example Construction

[0030] The preparation process of above-mentioned antibacterial agent A is:

[0031] S1. Zeolite modification:

[0032] First, the purchased natural zeolite was repeatedly washed with distilled water, filtered and dried at 100°C for 12 hours;

[0033] Then, add hydrochloric acid, potassium hydroxide, sodium chloride solution in the flask, add distilled water again and dilute to 80ml, control hydrochloric acid, potassium hydroxide, sodium chloride concentration to be 0.5, 0.4, 0.9mol / L respectively, add 8.9g zeolite , heated in a water bath, stirred at a constant speed at 94°C for 6h, washed with distilled water until Cl-free - residue, and then calcined at 100°C for 12 hours to obtain a modified zeolite;

[0034] S2, prepare antibacterial agent A

[0035] Mix tetrabutyl titanate, absolute ethanol, and nitric acid at a volume ratio of 6:24:1, add calcium chloride powder, and control the doping of metal calcium ions on TiO 2 The mass fraction in is 1.7wt.%, magnetically stir...

Embodiment 1

[0059] In this example, a kind of polyester fiber with good antibacterial performance is mixed with antibacterial agent A and antibacterial agent B to form a mixed antibacterial agent, and then pure PET slices are blended with the mixed antibacterial agent to prepare antibacterial modified PET slices, and then passed Polyester fibers with good antibacterial properties were obtained by melt spinning.

[0060] The above-mentioned polyester fibers include: 0.7wt.% of antibacterial agent A, 0.3wt.% of antibacterial agent B, and the balance of polyester fiber according to weight percentage.

[0061] Wherein, the antibacterial agent A is TiO prepared by gel-sol method 2 / Zeolite antibacterial agent, zeolite as carrier, TiO 2 doped with metallic Ca 2+ ion. TiO 2 / zeolite in the TiO 2 The loading amount is 35wt.%, Ca 2+ ions in TiO 2 The doping mass fraction is 1.7wt.%.

[0062] The antibacterial agent B is Cu prepared by gel-sol method 2 O / zeolite antibacterial agent, zeoli...

Embodiment 2

[0065] In this example, a kind of polyester fiber with good antibacterial performance is mixed with antibacterial agent A and antibacterial agent B to form a mixed antibacterial agent, and then pure PET slices are blended with the mixed antibacterial agent to prepare antibacterial modified PET slices, and then passed Polyester fibers with good antibacterial properties were obtained by melt spinning.

[0066] The above polyester fibers include: 1.0wt.% of antibacterial agent A, 0.5wt.% of antibacterial agent B, and the rest of polyester fiber according to weight percentage.

[0067] Wherein, the antibacterial agent A is TiO prepared by gel-sol method 2 / Zeolite antibacterial agent, zeolite as carrier, TiO 2 doped with metallic Ca 2+ ion. TiO 2 / zeolite in the TiO 2 The loading amount is 35wt.%, Ca 2+ ions in TiO 2 The doping mass fraction is 1.7wt.%.

[0068] The antibacterial agent B is Cu prepared by gel-sol method 2 O / zeolite antibacterial agent, zeolite as carrier...

Abstract

The invention relates to polyester fiber with good antibacterial property. The polyester fiber is prepared by the following steps of: mixing an antibacterial agent A and an antibacterial agent B to form an antibacterial agent mixture, then blending pure PET (Polyethylene Terephthalate) slices and the antibacterial agent mixture to prepare antibacterial modified PET slices, and then adopting a meltspinning mode to obtain polyester fiber with good antibacterial property, wherein the antibacterial agent A is TiO2/zeolite antibacterial agent, and the antibacterial agent B is Cu2O/zeolite antibacterial agent.

Description

technical field [0001] The invention relates to the field of polyester fibers, in particular to a polyester fiber with good antibacterial properties. Background technique [0002] With the development of the economy and the continuous improvement of modern living standards, people pay more and more attention to environmental cleanliness and self-protection. Microorganisms are closely related to people's daily life, and people live surrounded by microorganisms. However, some microorganisms are extremely harmful to people, and they will multiply in large numbers in a suitable environment, leading to the spread and spread of pathogenic bacteria. The polyester fiber products used in daily life are especially suitable for the reproduction of bacteria due to their porosity and moisture, which will not only emit unpleasant odors, but also stimulate the skin and induce various diseases. Therefore, the antibacterial properties of polyester fibers are obvious. Particularly important....
