PVC coated tent fabric is made with polyester scrim and coated with PVC. They are the most popular coated fabrics for different tent applications. Usually tent fabric require strong tearing strength, tensile strength, adhesion strength, waterproof, blockout, fireproof, anti-UV, long durable time and self-cleaning features etc.
Tearing, tensile and adhesion strength:
Tearing strength is the strength required to start or continue the tear in a fabric under specific condition & tearing force is the required to continue a tear previously started in a fabric.
A fabric may be torn when it is snagged by a sharp object and the immediate small puncher is converted into long rip by what may be a very small extra effort. The tearing strength is the resistance of fabric when tearing. The tearing strength for PVC coated tent fabric is vital. If the tearing strength is high, it means punctures in the fabrics do not propagate easily.
Tensile strength is the amount of load or stress that can be handled by a material before it stretches and breaks. Tensile strength is the material’s resistance to tension that is caused by mechanical loads applied to the material. The ability to resist breaking under tensile stress is one of the most important for PVC coated tent fabric and widely measured properties of materials used for structural applications.
Adhesion strength means the ability of an adhesive to stick to a surface and bond two surfaces together. Strength is an important factor for PVC coated tent fabric to consider when choosing an adhesive. PVC tarpaulin tent fabric required high adhesion strength.
Water-resistant and waterproof often refer to resistance to penetration of water on the surface of PVC coated tent fabric and possibly under pressure, whereas damp proof refers to resistance to humidity or dampness. When we produce PVC coated tent fabric, waterproof is required.
Blockout/Opaque PVC Coated Tent Fabric, with high level of anti-UV to protect your tents from the sun, the 100% blockout is reducing the heat from the sun, to save energy from hot area. Blockout tent fabrics are opaque with black in the middle and do not allow most light to get through.
Flame resistant or fire resistant materials are designed to prevent the spread of fire and withstand heat. Flame resistant materials should self-extinguish once the source of ignition is removed. UNISIGN PVC coated tent fabric are chemically treated to be slow burning or self-extinguishing when exposed to an open flame.
When we produce PVC coated tent fabric, we need to consider fireproof to protect the tent from fire when people are under the tent. It is the one of most features for PVC coated tent fabric.
PVC coated tent fabrics are most commonly made with acrylic lacquered on both sides of the scrim. Acrylic coating will reach self-cleaning for PVC coated tent fabric. As PVC coated tent fabric is always installed in high point, self-cleaning is very important for tent fabric. Acrylic coatings provide additional UV resistance which extends the life of the fabric, and some provide a surface that is dirt-repellent.
