Problems solved by technology

[0005] However, polyester is easy to stain and has a strong affinity for oil stains. Physical contact, chemical reactions, static effects, etc. can make it easily contaminated with pollutants
The car seat cover is inconvenient to remove and wash frequently. After being stained with oil and water, it will not only leave stains, affect the appearance, reduce the thermal comfort and mechanical properties of the fabric, but also may promote the reproduction and growth of bacteria, which is not conducive to driving. personnel health
Perfluoroalkyl CnF2n+1 has low surface tension and good water and oil repellency, which can significantly reduce the surface free energy of the monofilament, so that it is not wetted by various liquids, and contains long carbon chain perfluoroalkyl (C≥8) Due to the synergistic effect of long carbon chain and excellent crystallinity, it has the best water and oil repellency performance, but its products are difficult to degrade and have potential harm to the environment and human body, and have been completely banned from use.

Embodiment 1

[0024] A kind of preparation method of polyester monofilament for weaving net cloth is characterized in that: comprise the following steps:

[0025] (1) Preparation of nanometer mesoporous silica: ① mix absolute ethanol and 1% ammonia solution at room temperature, add cationic surfactant cetyltrimethylammonium bromide and nanometer silicon dioxide (nano The specific surface area of ​​silicon oxide is greater than 180g / m 2 , the mass ratio of surfactant to silicon dioxide is 0.2:25), stirred in a constant temperature water bath at 40°C at a speed of 350r / min for 10min to obtain a mixed solution, and ultrasonically dispersed for 1h. ② Slowly add tetraethyl orthosilicate to the mixed solution at a rate of 22ml / min under stirring, and stir at a speed of 230r / min in a water bath at 50°C for 2 hours to obtain a mixed reaction solution.

[0026] (2) Surface modification of nano-silica with fluorine-containing silyl compounds: ①Add 3,3,3-trifluoropropylmethoxysilane to the above mixe...

Embodiment 2

[0043] Only change the cationic surfactant used in embodiment 1 step (1), described cationic surfactant is alkyl trimethyl ammonium chloride, cetyl trimethyl ammonium bromide, lauryl pyridinium chloride Onium, Stearyl Trimethyl Ammonium Chloride, Fluorohexyl Trimethyl Ammonium Chloride, Dimethyl Monococoyl Ammonium Acetate, Octadecyl Dimethyl Vinyl Phenyl Ammonium Chloride, Didodecane One of the base amine polyoxyethylene ether ammonium chloride. The rest are the same as implementation case 1.

Embodiment 3

[0044] Embodiment 3: Only replace the mesoporous silica in embodiment 1 with other inorganic nanoparticles, and the inorganic nanoparticles are one of nano-TiO2 and nano-ZnO. Nano-zinc oxide and nano-titanium dioxide are direct wide-bandgap semiconductors, which can be effectively excited by ultraviolet light, have photocatalytic properties, have a certain self-cleaning ability, and can form protrusions on the surface of monofilaments. watery. All the other are with embodiment 1.

Abstract

The invention discloses a preparation method of a polyester monofilament for woven mesh cloth. The preparation method comprises the following steps: preparing nano mesoporous silicon dioxide, modifying the surface of the nano silicon dioxide by using a fluorine-containing silyl compound, preparing PET (Polyethylene Terephthalate) water-repellent and oil-repellent master batch, and spinning. The prepared polyester monofilament for the woven mesh cloth has the advantages of good toughness and water and oil repellency, is not easy to stain and can keep clean all the time, so that the cleaning cost is saved, and the pollution of a detergent to the environment is also reduced; the prepared polyester monofilament for the woven mesh does not generate the problem of biological accumulation, and the harm to the environment can be reduced; the prepared polyester monofilament for the woven mesh cloth can weaken sound energy and has the effects of absorbing sound and reducing noise.

Description

technical field [0001] The invention relates to a preparation method of polyester monofilament for weaving mesh cloth. Background technique [0002] Polyester such as polyester has been widely used as raw materials for car seat fabrics, of which 72% are in Western Europe, 69% in Japan, and 60% in the United States. Due to its excellent mechanical properties and chemical stability, polyester is one of the most important fiber raw materials in the field of nonwovens. It is very popular in the application of car seat fabrics, and the fabrics are crisp and durable. However, polyester is easy to stain and has a strong affinity for oil stains. Physical contact, chemical reactions, static effects, etc. can make it easily contaminated with pollutants. The car seat cover is inconvenient to remove and wash frequently. After being stained with oil and water, it will not only leave stains, affect the appearance, reduce the thermal comfort and mechanical properties of the fabric, but al...
