Problems solved by technology

[0002] The surface of the existing umbrella fabric is coated with waterproofing agent and water-repellent layer. Under the ordinary water shower test, the water droplets can only slide off the fabric for a short time without wetting the fabric. After a little longer, the fabric will be wet, which makes it difficult for the water droplets to adsorb on the surface of the fabric. spin dry
[0003] Moreover, the PH value of rainwater in daily life contains impurities and is acidic to a certain extent, which indirectly leads to the poor hydrophobicity of the rainwater after the current umbrella fabric has been used for a while, so it is adsorbed on the fabric and wets the umbrella surface. After every rain, Ordinary umbrellas are often wet and inconvenient to store after use, and they are scattered everywhere, causing great trouble to the indoor environment and inconvenient to carry
After entering various public places, many need to add a plastic bag to hold the umbrella that is still dripping, resulting in waste of resources and environmental pollution caused by the used plastic bag

Abstract

The invention relates to a water-shedding fabric. Superfine polyester fiber is employed to weave a high density plain weave fabric, and a hydrophobic coating is disposed on the surface of the fabric, wherein the hydrophobic coating feed liquid comprises the following components: a 50-70g / L three-proofing assistant; 25-35g / L melamine resin; a 5-15g / L silicon smoothing agent; a 3-7g / L crosslinking agent; and a 0.5-1.5g / L high concentration agent. The invention also provides an umbrella processed from the hydrophobic fabric. The umbrella provided by the invention has excellent hydrophobic properties.

Description

Technical field [0001] The present invention relates to the technical field of functional fabrics, in particular to a non-sticky fabric and an umbrella made from the fabric. Background technique [0002] The surface of the existing umbrella fabric is coated with a waterproofing agent and a water-repellent layer. Under the ordinary water shower test, the water droplets can only slip off the non-wetting fabric for a short time. A longer time means that the fabric will get wet, making it difficult for water droplets to adsorb on the surface of the fabric. Spin dry. [0003] In addition, the pH value of rainwater in daily life contains impurities and is acidic to a certain extent, which indirectly leads to the poor hydrophobicity of the rainwater under the umbrella fabric after being used for a while, so that it is adsorbed on the fabric and wets the umbrella surface. Every time it rains, Ordinary umbrellas are often wet and inconvenient to store after use, and they are everywhere, wh...
