Embodiment 1

[0026] Step 1: Pretreat the fabric to be sprayed with low-temperature plasma, with a treatment power of 150W and a treatment time of 20 minutes. The humidity of the fabric measured by the YG(B)216-II fabric moisture permeability meter is 90%.

[0027] Step 2: Preparation of TiO 2 EFI solution, TiO 2 The sol is 0.5wt%. If the sol is still clear and transparent after standing for 24 hours, and there is no layering or precipitation, it can be considered that the sol is uniformly dispersed and the system is stable. TiO 2 The sol is used as the electrospray solution because the TiO 2 The dispersion uniformity of the powder in the solution is not high, and it is easy to coalesce and settle for a long time, while TiO 2 The sol itself is nano TiO 2 Uniform dispersion of particles with other forms of TiO 2 Material incomparable affinity.

[0028] Step 3: Place the fabric facing the injection needle spray port of the high-voltage electrostatic spraying equipment. The distance betw...

Embodiment 2

[0032] Step 1: Pretreat the fabric to be sprayed with low-temperature plasma, the treatment power is 250W, the treatment time is 10min, and the humidity of the fabric is 80% as measured by the YG(B)216-II fabric moisture permeability meter.

[0033] Step 2: Preparation of TiO 2 EFI solution, TiO 2 The concentration of the sol is 0.8wt%;

[0034] Step 3: Put the fabric facing the injection needle spray port of the high-voltage electrostatic spraying equipment. The distance between the fabric and the injection needle spray port is 10cm. The electrospray solution is atomized into micron or nanometer particles and evenly loaded on the surface of the fabric. The flow rate of the high-voltage electrostatic spray solution is 0.5mL / h, the voltage is 20kV, and the receiving time is 15min;

[0035] Step 4: drying the textile obtained in step 3 for 20 minutes, and finally obtaining an anti-ultraviolet textile.

Embodiment 3

[0038]Step 1: Pretreat the fabric to be sprayed with low-temperature plasma, the treatment power is 450W, the treatment time is 30min, and the humidity of the fabric is 70% as measured by the YG(B)216-II fabric moisture permeability meter.

[0039] Step 2: Preparation of TiO 2 EFI solution, TiO 2 The concentration of the sol is 1.5wt%;

[0040] Step 3: Put the fabric facing the injection needle spray port of the high-voltage electrostatic spraying equipment. The distance between the fabric and the injection needle spray port is 20cm. The electrospray solution is atomized into micron or nanometer particles and evenly loaded on the surface of the fabric. The flow rate of the high-voltage electrostatic spray solution is 0.3mL / h, the voltage is 20kV, and the receiving time is 20min;

[0041] Step 4: Drying the textile obtained in step 3 for 30 minutes to obtain an anti-ultraviolet textile.

Abstract

The invention provides an electrostatic spraying method of anti-ultraviolet fabrics and relates to the technical field of textile materials. The method includes the steps of 1, subjecting fabric to low-temperature plasma surface treatment under the power of 100-500w for 10-90min so that moistness of the fabric reaches 70-100%; 2, preparing anti-ultraviolet electrospray solution; 3, aligning the fabric with a spray orifice of an injector needle of a high-pressure electrostatic spraying device, keeping the fabric 10-30cm away from the spray orifice, and allowing the anti-ultraviolet electrospray solution to be evenly carried to the surface of the fabric; 4, drying the treated fabric for 5-30min to obtain the anti-ultraviolet fabric. Compared with the prior art, the method has the advantages that flexural rigidity of the fabric is increased by 10-20%; drape coefficient is increased by 3-10%; after washed 10 times, UPF (ultraviolet protection factor) is greater than 40, and UVA (ultraviolet A) average transmittance is less than 5%; process equipment is simple, operating is convenient, process parameters are easy to control, costs are low, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to an electrostatic spraying method for anti-ultraviolet textiles. Background technique [0002] With the development of science and technology and the continuous progress of society, the environmental pollution caused by industrial production has caused the destruction of the atmospheric ozone layer, and the harm caused by ultraviolet radiation to people's health has become increasingly significant. Long-term ultraviolet radiation will accelerate skin aging and produce pigmentation. Even reduce the body's immunity, resulting in skin cancer. With the continuous improvement of people's living standards, the anti-ultraviolet properties of textiles have attracted more and more attention, and the development of anti-ultraviolet textiles has become an important research direction. [0003] Chinese patent application CN102995406B discloses a preparation method of an anti-ultrav...
