What are the main waterproof technologies of textile fabrics
The waterproof coated fabric is a new type of textile fabric, which is composed of high molecular waterproof and breathable material plus fabric composite fabric. It mainly has the functions of moisture permeability, breathability, and insulation. The textiles of waterproof fabrics have the properties of oil repellency, water repellency, and water pressure resistance. Waterproof coated fabrics are commonly used in outdoor clothing such as jackets.
With the improvement of consumption level and the popularity of outdoor activities such as snowboarding, surfing, cycling, and outdoor camping in China, the application of waterproof finishing has become more and more extensive, and the requirements have become higher and higher, especially in terms of outdoor activity equipment.
In mountaineering, a complete set of equipment includes at least: jackets, outdoor tents, thermal clothing, waterproof shoes, waterproof raincoats, etc. These types of equipment all have one thing in common, and that is waterproofing. Stretchable waterproof material for outdoor covers is widely used in outdoor clothing, and it is often seen in luggage, shoe materials, outdoor tents, etc.
So what are the methods of fabric waterproof production and processing?
Tight weave
The first waterproof finishing is to use the high-density fiber textile method, which is often referred to as compact fabric. This type of finishing method is currently mostly used for polyester or fiber textiles. The yarns are closely arranged, and the water pressure resistance can reach 104-105Pa. This type of fabric has high density, and poor tear performance in the textile and the spinning fabric must be specially treated, the production cost is high, and the processing is difficult, so it is rarely used.
Coating finishing method
The coating method is mainly to coat a layer of film on the surface of the fabric through lamination or coating process, so that the pores on the surface of the fabric are closed, so as to obtain waterproof performance. Although the products obtained by this method are impermeable to water, they are also not breathable. They are mostly used in the production of rain-proof tarpaulins, umbrellas, and other open-use products that are not suitable for wearing. With the extension of late technology, waterproof and moisture-permeable coatings have also appeared, and the application in clothing is mainly sun protection.
Hydrophobizing agent finishing method
This method is to form a hydrophobic gene on the surface of the fabric to prevent water molecules from passing through the material, thereby achieving the purpose of waterproofing. This is the so-called lotus leaf effect.
The dip rolling of this method is usually carried out under normal temperature conditions, that is, the so-called lotus effect. This kind of process is simple and easy to implement, and the cost is low.
There are many types of hydrophobic agents suitable for this type of process, such as the early aluminum soap water repellent, paraffin emulsion, etc., and the recent silicone, organic fluorine, etc. At present, fluoride water repellent is the most cost-effective and most widely used among these water repellent finishing agents, namely C8 water repellent, and C6 water repellent.
