Problems solved by technology

However, due to the barrier material of the film type, as mentioned above, it has almost no breathability, and the material is relatively stiff and wearable. For operators, wearing this type of protective clothing for long-term work is a great test for physical function.
[0008] In view of this, the present invention provides a water-soluble protective material with good air permeability (including particulate matter and limited liquid splashing) with a certain barrier efficiency, which effectively solves the problem that the current water-soluble protective materials cannot have both protective performance and air permeability question

Embodiment 1

[0045] The dissolving temperature is 80 degrees centigrade, and the polyvinyl alcohol spun-bonded non-woven fabric of 45 grams per square meter is passed through the hydrophobic coating nozzle, and the hydrophobic coating treatment is carried out by spraying.

[0046] The hydrophobic coating material used was an alkoxysilane coating with a solids content of 1%. Afterwards, the material is dried in an environment of 105 degrees Celsius to remove the solvent while cross-linking and curing the surface of the alkoxysilane.

[0047] The added amount of the coating is 0.1% of the mass of the non-woven fabric.

Embodiment 2

[0049] The dissolving temperature is 80 degrees centigrade, and the polyvinyl alcohol spun-bonded non-woven fabric of 45 grams per square meter is immersed in the hydrophobic coating solution, and the hydrophobic coating treatment is carried out by dipping method.

[0050] The hydrophobic coating material used was an alkoxysilane coating with a solids content of 1%. Afterwards, the material is dried in an environment of 105 degrees Celsius to remove the solvent while cross-linking and curing the surface of the alkoxysilane.

[0051] The added amount of the coating is 0.5% of the mass of the protective material.

Embodiment 3

[0053] The dissolving temperature is 80 degrees centigrade, and the polyvinyl alcohol spun-bonded non-woven fabric of 45 grams per square meter is passed through the hydrophobic coating nozzle, and the hydrophobic coating treatment is carried out by spraying.

[0054] The hydrophobic coating material used was an alkoxysilane coating with a solids content of 2%. Afterwards, the material is dried in an environment of 105 degrees Celsius to remove the solvent while cross-linking and curing the surface of the alkoxysilane.

[0055] The added amount of the coating is 0.5% of the mass of the protective material.

Abstract

The invention discloses a waterproof breathable water-soluble protective material, and relates to the technical field of protective products. The waterproof breathable water-soluble protective material comprises a water-soluble spunbond base material and a hydrophobic coating, or the waterproof breathable water-soluble protective material comprises the water-soluble spunbond base material, the hydrophobic coating and a barrier layer, the raw material of the water-soluble spunbond base material is selected from at least one of polyvinyl alcohol, water-soluble cellulose, polyethylene glycol and water-soluble chitosan, the hydrophobic coating is selected from at least one of a fluorine / silicon resin material, alkoxy silane and an inorganic nano material; and the barrier layer is selected from at least one of a water-soluble melt-blown non-woven fabric, a water-soluble centrifugal spinning non-woven fabric, a water-soluble swelling non-woven fabric and a water-soluble electrostatic spinning non-woven fabric. The waterproof breathable water-soluble protective material is high in barrier efficiency and good in air permeability, and can effectively solve the problem that the protective performance and the air permeability of the existing water-soluble protective material cannot be achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of protection and non-woven fabrics, in particular to a waterproof and breathable water-soluble protection material. Background technique [0002] Protective fabrics (excluding hazardous chemical protection) are usually divided into the following four categories in terms of materials: [0003] 1. Spun-bonded materials: This type of protective clothing only provides limited protection against large particles of dust, and cannot provide effective protection against small particles of dust that may be produced in industrial production, such as PM2.5, PM1.0 or PM0.3, but this Such materials have good air permeability. After being made into protective clothing, they have soft texture and high wearing comfort, and are widely used in places with low protection requirements; As a skeleton material, spunbond materials provide mechanical support for melt-blown materials that provide barrier properties. The protective...
