Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a composite finishing agent and antibacterial and anti-mosquito polyester fabric. Background Art

[0002] Polyester is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation. The fibers made through spinning and post-treatment have the advantages of high strength, good elasticity, and good shape retention. They are widely used in clothing manufacturing and other fields. However, when polyester is made into summer clothing fabrics, due to the hot weather and high sweating, clothing is prone to breeding bacteria, threatening human health. At the same time, summer is also the season when mosquitoes are rampant. Whether outdoors or indoors, thin clothes and exposed arms and legs cannot resist mosquito bites. There are many common methods to prevent mosquito bites, mainly mosquito coils, electric mosquito liquid, mosquito nets and mosquito lamps. The use of mosquito coils and electric mosquito liquid requires a ventilated environment, otherwise the smell in the closed indoor air will harm human health, but the mosquito repellent effect is not long-lasting after ventilation; the use of mosquito nets and mosquito killers has certain limitations, the operation is cumbersome, they cannot be carried around, and the convenience is poor. Thick clothes can prevent mosquito bites, but they are not suitable for summer wear, and the ordinary fabrics on the market cannot achieve the effect of mosquito repellent. Therefore, it is often necessary to modify the fabric to make it both mosquito repellent and sweat-wicking.

[0003] At present, most polyester fabrics with anti-mosquito effect are obtained by soaking polyester fabric or polyester fiber in mosquito repellent liquid and then drying it. For example, CN113832727A discloses a method for preparing high-strength polyester fabric, wherein the polyester fabric is immersed in a coating liquid to obtain a coated fabric, and the coated fabric is immersed in a drug solution; wherein the drug solution is one or more of wormwood, patchouli, mint, angelica, calamus or clove, and the drug solution plays an antibacterial and anti-mosquito effect. However, the plant-derived antibacterial and anti-mosquito component is not easy to adhere to the polyester fabric, and because the plant-derived component is volatile, the antibacterial and anti-mosquito effect of the obtained fabric is short.

[0004] CN113174675A discloses a method for preparing polyester fabrics in order to improve the soaking and compounding method, wherein an antibacterial mosquito repellent liquid is squeezed and sprayed on the surface of polyester long threads and elastic long threads, and the polyester long threads and elastic long threads sprayed with the antibacterial mosquito repellent liquid are dried and shaped when passing through a drying box, so that the antibacterial mosquito repellent liquid adheres to the surface of the polyester long threads and the elastic long threads to form antibacterial spinning threads, and the prepared polyester fabric has antibacterial properties, which prevents bacteria from growing on the skin due to poor sweat absorption of the polyester fabric during summer sweating, and has the effect of repelling mosquitoes. However, the antibacterial mosquito repellent liquid is squeezed and adhered to the surface of the polyester long threads, and the adhesion between the two is small, and it is easier to fall off from the surface of the polyester long threads when washed, making it difficult to achieve long-term antibacterial and mosquito-proofing.

[0005] Therefore, there is an urgent need to develop a modified polyester fabric that has a high bonding strength between the antibacterial and anti-mosquito component and the fabric and has high antibacterial and anti-mosquito efficiency and durability. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a composite finishing agent and antibacterial and anti-mosquito polyester fabric.

The test method referred to the standard GB / T20944.3-2008 "Evaluation of Antibacterial Properties of Textiles Part 3: Oscillation Method". The test results are shown in Table 1:

[0259] Table 1

[0260]

[0261]

[0262] (2) Mosquito repellent performance test

[0263] The anti-mosquito performance of the antibacterial and anti-mosquito composite fabrics prepared in Application Examples 7-12 and Comparative Application Examples 3-4 was tested respectively. The test method referred to the standard GB / T30126-2013 "Testing and Evaluation of Anti-Mosquito Performance of Textiles". The test results are shown in Table 2:

[0264] Table 2

[0265]

[0266] As shown in Table 1 and Table 2, the antibacterial and mosquito-proof composite fabric prepared by the present invention has good antibacterial and mosquito-proof properties. 3-phenylpropenal and 4-allyl-2-methoxyphenol are used as aromatic antibacterial and mosquito-proof materials, and nano zinc oxide is used as an inorganic antibacterial material to modify polyester fabric together, which can effectively improve the antibacterial and mosquito-proof effect of polyester fabric. 3-phenylpropenal, 4-allyl-2-methoxyphenol and alkenyl-modified nano zinc oxide are connected to polyester molecules with stable chemical bonds through free radical polymerization, which effectively improves the bonding strength of nano zinc oxide and polyester, avoids the problem of reduced antibacterial and mosquito-proof effect caused by the high volatility of 3-phenylpropenal and 4-allyl-2-methoxyphenol, and the antibacterial and mosquito-proof effect of polyester fabric is long-lasting. After washing 30 times, the antibacterial rate is still above 90%, and the anti-mosquito repellent rate can reach above 85%.

[0267] Compared with Application Example 7, in Comparative Application Example 3, the polyester fabric was not olefin-modified, and 3-phenylacrolein, 4-allyl-2-methoxyphenol and olefin-modified nano zinc oxide in the composite finishing agent underwent polymerization, and the polymerization product was entangled with the polyester molecular chain. However, since the antibacterial and anti-mosquito component was not connected to the polyester molecule with a stable chemical bond, the bonding strength with the polyester fabric was reduced, and the antibacterial and anti-mosquito performances were reduced. After multiple washings, the antibacterial and anti-mosquito component was further separated from the polyester fabric. , the antibacterial and mosquito-proof properties are greatly reduced; in comparative application example 4, 3-phenylacrolein, 4-allyl-2-methoxyphenol and nano zinc oxide in the antibacterial and mosquito-proof components are only adsorbed on the polyester fabric, and the surface of the polyester fabric is flat and smooth, the adsorption effect is weak, and 3-phenylacrolein and 4-allyl-2-methoxyphenol are volatile, so the antibacterial and mosquito-proof properties of the modified polyester fabric are significantly reduced. After multiple washings, the antibacterial and mosquito-proof properties of the modified polyester fabric are reduced more significantly.

[0268] The applicant declares that the above is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto.
