Understanding the Product
 
The DAF standard product is a three-ply fabric consisting of a piece of scrim laminated between two sheets of polyvinyl film (PVC).
 
Scrim is loosely woven material which can be made out of cotton, fiberglass, nylon, polyester, or a combination.  DAF uses mostly polyester scrim.
The polyester is measured by the weights of the thread (denier) and the density of the weave (threads per inch) or count.  The heavier the weight the higher the denier.  A 9x9 scrim has 9 threads per inch by 9 threads per inch.  The first number is the number of threads in the machine direction (or warp) and the second number is the number of threads in the cross direction (or fill).
 
The vinyl is measured by its thickness (1 mil is 1/1000 of an inch).  Vinyl is treated to have certain properties such as flame retardant, antimicrobial, antistatic, and ultra violet protected.
 
The laminated product has a weight which is measured in ounces per square yard.  For example: one square yard of a 13 oz. material weighs 13 ounces.
 
As the material is put through the laminator, it is also embossed.  An embossing is the surface texture.  DAF’s most common embossings are matte, taffeta, and polish.  Our banner products usually have a matte finish for smoothness.  Our tent products often have a polish finish, and our hospital products, such as mattress ticking have a taffeta finish.
 
The material is rolled onto a cardboard core.  Our standard core size is 3” inside diameter, but occasionally we will use a 2” core.
 
The polyvinyl chloride (PVC) films were complemented by polyurethane films and coatings, silicone coatings, acrylic coatings, and blended rubber coatings. All of these films and coatings are reinforced with nylon and polyester fabrics which are non-wovens, wovens, and knits.  There are many other films, fabrics, and foil that can be coated and laminated for a variety of special applications.
 
DAF does extensive testing on our products to make sure that they meet industry and customer standards.  Properties tests for: flame resistance, bacterial resistance, mildew resistance, fungus resistance, adhesion, moisture vapor transition rate, fluid resistance, burst strength, tensile strength, tear strength, etc.  DAF adheres to standard Federal testing methods where applicable.
