1. What is waterproof fabric?

The water repellency of a fabric refers to the ability of the fabric to bounce water droplets off its surface. The purpose of water-repellent finishing is to prevent water from wetting the fabric and prevent the penetration of liquid water, but still maintain the air permeability and moisture permeability of the fabric.

Waterproof finishing can usually be divided into breathable and breathable according to the permeability of waterproof fabrics after processing. Fabric breathable finish is also called coating finish, it is on the surface of the fabric coated with breathable, insoluble in water continuous film, so the fabric is not breathable. Wearing clothing made of this kind of fabric will make people feel stuffy, but it can be used to make tents, raincoats and other supplies.

Oilcloth (tung oil, flax oilcloth, etc.) adopted very early in China belongs to this category. In order to improve the feel, elasticity and durability of finishing products, recently, more polymer materials with high adhesive force, good elasticity, soft feel and aging resistance are used for coating processing, commonly used rubber and plastic (polyacrylate and polyurethane). Breathable waterproof finishing is also known as water-repellent finishing, it changes the fiber surface performance, so that the hydrophilicity of the fiber surface becomes hydrophobic, and the waterproof fabric still retains a large number of gaps between the fibers and yarns, such waterproof fabric can be breathable, and is not easy to be moistened by water, only in the case of considerable water pressure before the occurrence of water permeability phenomenon, suitable for raincoat.

Waterproof and moisture permeable functional fabric

First, through the fiber to achieve moisture permeability
1. Ventel fabric. An early waterproof and wet-permeable fabric was the famous Ventile fabric. It was designed by the Shirley Institute in the United Kingdom in the 1940s, using Egyptian long staple cotton of high weight and low twist pure cotton yarn high density flat fabric, mainly used in the British Air Force pilots during the Second World War. When the fabric is dry, the gap between the warp and weft yarns is large, about 10 microns, which can provide a highly permeable structure; When rain or water drenches the fabric, the cotton yarn expands, reducing the gap between the yarns to 3 to 4 microns. This closed-cell mechanism is combined with a special water-repellent finish to ensure that the fabric is not further penetrated by rain. At present, this kind of fabric has long been replaced by other waterproof and permeable fabrics.

2. Coolmax fabrics. Dupont, Japan's Toray and other international companies research the way to create pores inside the fiber to achieve sweat out of the body, that is, the moisture absorption and perspiration fabric on the market. This kind of fiber production technology is concentrated in the hands of such international large companies, the price is relatively high, it is difficult to become the mainstream of the market.

Second, through the coating to achieve moisture permeability
Using dry direct coating, transfer coating, foam coating, phase inversion or wet coating (solidification coating) and other technology, a variety of waterproof, moisture permeable coating agents are coated on the surface of the fabric, so that the surface pores of the fabric are closed by the coating agent or reduced to a certain extent, so as to obtain water resistance. The moisture permeability of the fabric is obtained by the interaction of the microporous structure formed by a special method on the coating or the hydrophilic groups in the coating agent with water molecules, and the adsorption of water molecules on the high humidity side with the help of hydrogen bonds and other intermolecular forces, and then transferred to the low temperature side for analysis. The price of coated fabrics is low, and a certain degree of moisture permeability is achieved, and it is widely used. However, due to its poor waterproof and moisture permeability, the feel is not satisfactory, and the market share is gradually decreasing.
Now the developed wet transfer coating fabric makes the coated fabric a new machine, it is not only waterproof and moisture permeability and other physical indicators are high, the face cloth can do 100% Teflon treatment, washing fastness can reach more than 25 times, and feel very good.
