Problems solved by technology

However, this broad-spectrum antibacterial negative ion carpet has the following main disadvantages: the negative ion anti-mite antibacterial fiber film layer plays the functions of negative ion release and anti-mite antibacterial, wherein the functional nanoparticles realize the negative ion release function, and chitosan realizes the antibacterial function
The health-care carpet has the following major deficiencies: the patent focuses on protecting the structure of the carpet, and does not describe in detail the negative ion fiber felt, absorbing layer and other parts that perform negative ion release and antibacterial functions

preparation example Construction

[0029] A kind of preparation method of releasing the antibacterial polypropylene fiber yarn of negative ion comprises the steps:

[0030] Step 1, surface modification treatment of tourmaline powder particles.

[0031] Tourmaline powder belongs to natural mineral materials. It is a silicate mineral with a complex ring structure characterized by boron content (edited by Tian Junying, Yang Wenfang, Niu Jiarong, etc., "Functional Finishing of Textiles", China Textile Publishing Society, 2015.10). After grinding, the particle size is reduced. The tourmaline powder selected in the present invention includes manganese tourmaline powder, ferrotourmaline powder, lithium tourmaline powder and magnesium tourmaline powder. 6000-mesh powder is preferred, and 10000-mesh powder and 12000-mesh powder are more preferred.

[0032] Tourmaline is a natural mineral material with a Mohs hardness of 7-7.5, which is harder than steel, teeth, and quartz. The harder the material, the more difficult...

Embodiment 1

[0048] Example 1: Preparation of antibacterial polypropylene yarn releasing negative ions with a tourmaline powder content of 0.4% and the resulting carpet.

[0049] Step 1, surface modification treatment of tourmaline powder particles;

[0050] (1) Mix the tourmaline powder particles and the interface compatibilizer uniformly at room temperature.

[0051] Weigh the tourmaline powder and the interface compatibilizer, and mix them evenly in the mixing equipment. Mixing equipment speed: 100 rpm. Mixing time: 20 minutes. The absolute dry mass ratio of tourmaline powder to interface compatibilizer is 95:5. Thus, a normal-temperature mixture of tourmaline powder particles and an interface compatibilizer is obtained. Among them, the tourmaline powder is: 12000 mesh iron tourmaline powder particles. The interface compatibilizer is a mixture of hydroxyethyl ethylene bis stearamide and liquid paraffin (distillation temperature > 300° C.) according to the dry mass ratio of 4:1.

Embodiment 2

[0056] Embodiment 2: Preparation of antibacterial polypropylene yarn releasing negative ions with 1.0% tourmaline powder content and the carpet obtained.

[0057] Step 1, surface modification treatment of tourmaline powder particles;

[0058] (1) Mix the tourmaline powder particles and the interface compatibilizer uniformly at room temperature. Weigh the tourmaline powder and the interface compatibilizer, and mix them evenly in the mixing equipment. Mixing equipment speed: 100 rpm. Mixing time: 20 minutes. The dry mass ratio of tourmaline powder to interface compatibilizer is 90:10. Thus, a normal-temperature mixture of tourmaline powder particles and an interface compatibilizer is obtained. Among them, the tourmaline powder is: 10000 mesh iron tourmaline powder particles. The interface compatibilizer is a mixture of hydroxyethyl ethylene bis stearamide, polyethylene wax and liquid paraffin (distillation temperature > 300° C.) according to the dry mass ratio of 7:2:1.

Abstract

The invention relates to a preparation method of an antibacterial polypropylene fiber yarn capable of releasing negative ions and a polypropylene fiber carpet prepared by using the polypropylene fiber yarn. The preparation method mainly comprises the following steps: step 1, carrying out surface modification treatment on tourmaline powder particles; and 2, producing the antibacterial polypropylene fiber yarn capable of releasing the negative ions. In addition, the antibacterial polypropylene fiber carpet capable of releasing the negative ions is obtained by using the antibacterial polypropylene fiber yarn capable of releasing the negative ions obtained in the step 2 according to a conventional polypropylene fiber carpet preparation process. The antibacterial mildew-proof coating has the advantages of excellent antibacterial effect, high negative ion release amount and excellent mildew-proof effect; the preparation method is simple in process, free of special equipment and special auxiliaries and easy for large-scale batch production.

Description

technical field [0001] The invention belongs to the technical field of carpets, and in particular relates to a preparation method of an antibacterial polypropylene yarn releasing negative ions and a polypropylene carpet prepared by using the polypropylene yarn. Background technique [0002] Carpet is a floor covering made of cotton, linen, wool, silk, grass and other natural fibers or chemical synthetic fiber materials, which are knitted, tufted or woven by hand or mechanically. Carpets are widely used in various places such as hotels, hotels, homes, schools, meeting rooms, and airplanes. They have multiple functions such as moisture-proof, heat-insulating, reducing noise, and beautifying the indoor environment. With the continuous improvement of people's living standards and health awareness, higher demands are placed on the quality and function of carpets. [0003] Polypropylene is a chemical synthetic fiber material often used in carpets. There are many varieties of poly...
