The Snyder Process
THE LAMINATION PROCESS is deceptively simple. The most common laminates consist of a strong nylon or polyester scrim sandwiched between layers of vinyl (PVC) film using the right combination of heat, pressure, and adhesives.
SUBSTRATES. The substrate is the material that gives the laminate strength, and is usually laminated between two layers of film. In addition to the nylon or polyester scrims, which we produce ourselves, we can use non-woven such as Tyvec®2, Cerex®2, and needle-punched felt. We can also laminate cloth to cloth and cloth to vinyl, and can coat substrates.
SCRIMS can be woven or knit, nylon or polyester. Knit scrims have become very popular because of their high strength-to-cost ratio, low stretch and relatively flat appearance. Woven scrims are used where maximum strength is desired, such as in the fabric we produce for government use under MIL-C-43006. Polyester has replaced most of the nylon in scrims because it offers more dimensional stability, less stretch, better lay-flat, and is easier to flame retard.
EMBOSSING is done during the laminating process, and provides the different textures on the top surface of the laminate. The most common emboss is Faille (pronounced"file" and sometimes referred to as "taffeta"). Our LeatherLike® emboss is popular with manufacturers of athletic equipment, while Palomar is commonly used on awning and boat top fabrics. Our smooth, shiny Hi-Gloss emboss has made our WeatherSpan™ tent fabric the standard of the tent industry. AdverTex™ banner fabrics feature a Smooth Dull emboss suitable for both screen printing and vinyl graphics.
STRIPES are another Snyder specialty. Using our patented PermaBar™ process, we manufacture the stripes by laminating vinyl strips to the top surface of the laminate. This process is far superior to conventional printed stripes, because the stripes are highly resistant to abrasion and UV. you can custom design your own fabrics, selecting from a variety of colors and patterns.
FILMS. In addition to vinyl, we have the capability to laminate on any specialized films. Incoming films are subjected to thorough test procedures: color, gauge, stiffness and lacing. If the film fails to meet our quality standards, it is rejected.
ADHESIVES. We manufacture our own adhesives, formulating each one for the particular end use of the fabric. This is where we add generous amounts of anti-bacterial agents, mildew inhibitors, UV and heat stabilizers, and flame retardants as needed.
HIGH STANDARDS are maintained by our quality assurance personnel working in our federally-certified laboratory. Numerous quality checks are made on the raw components, the laminating process, and the finished goods.
