What is Carpet Backing
What is Carpet Backing?Buy NowCarpet backing material determines its longevity. It’s available in three material types, each with its unique characteristics.
Carpet backing refers to the underside of a carpet. Backing reinforces the carpet by holding the tufts in place. It enhances structural stability and provides extra protection against everyday wear and tear.
Carpets with backings made of recycled or natural materials are more sustainable. Carpet backing components may vary from one carpet brand to another.
Besides enhancing longevity, carpet backing also refines appearance retention. Locking the stitches into the primary backing strengthens the tuft bind. A solid tuft bind prevents edge raveling and zippering.
While secondary backing isn’t structural, it provides extra support to the carpet. Secondary backing is an insulation layer. It keeps the carpet from moisture absorption or harboring mold and bacteria.
Carpet backing also makes installation easier. Instead of using tack strips to hold the carpet in place, installers use tape on the backing.
Carpets have primary and secondary backing. Underneath the carpet, a primary backing forms a structural reinforcement. It’s a coarse element that holds the fibers together. The process includes adding an adhesive layer to the primary backing.
It helps bind the primary and secondary backing. The secondary backing often has several layers. Most carpet fibers are either woven or tufted. Since secondary backing isn’t a tufted element, it tends to be less rough.
There are two methods of applying primary and secondary backings. One is the puddling process, where a viscous polymer is attached to the carpet fiber. The other approach is to thrust a sheet onto the fiber.
Other manufacturers choose to attach a finished carpet backing. After applying the backings, the carpet is dried using an oven. It helps get rid of moisture from the adhesive.
Manufacturers use three carpet backing methods. They include latex, thermoplastics, and polyurethanes. Each carpet backing system has its benefits and downsides.
Latex is a water-based method used to make broadloom carpets. Most carpet manufacturers use the latex-backed method. Latex consists of polyurethane dispersion (PUD), vinyl acetate-ethylene (VAE), and styrene butadiene rubber (SBR).
Most latex-backed carpets are synthetic. The method uses synthetic adhesive chemistry. Polymer makes most of the raw material. Emulsion polymers make carpets that are durable, flexible, and water-resistant.
Manufacturers use the latex-based method since it’s cost-effective. It’s also ideal for making various carpet patterns and achieving a solid tuft bind. But, latex-backed carpets deteriorate over time when exposed to moisture.
There are three types of thermoplastics. They all offer dimensional stability and sturdy edge ravel. Some thermoplastics techniques protect against moisture retention. Like polyurethanes, thermoplastics are recyclable.
Thermoplastics come in three categories—PVC, polyolefins, and hotmelt backing systems.
Polyurethane is a plastic polymer material made of urethane links. Manufacturers use reactive chemistry to form the backing structure. Polyurethanes, like latex, can’t be recycled into new carpet backings.
Polyurethane-backed carpets have a polymeric bond between the primary and secondary backing. Their unique molecular structure forms a solid material that resists wear and tear.
They have sturdy adhesion properties, which enhance the tuft binding. The yarn also forms a tight weave. Besides its efficient edge-ravel and moisture protection, the technique is affordable.
Both are common in broadloom carpeting. Standard backings are often made of natural jute fiber or synthetic thermoplastic resin. They’re available in woven and non-woven constructions.
While standard backing is cheaper, performance backing has higher tuft bind elements. Standard backing has a limited warranty. Since performance backing is of a higher standard, it comes with a warranty of up to 10 years.
Choose standard backing if you’re carpeting a low-traffic area. Its counterpart has a thick latex backing ideal for high-traffic areas.
High-performance backing comes with denser latex. You also get a lifetime warranty. Manufacturers recommend glue-down installation for high-performance backings. It prevents moisture penetration and is suitable for high foot traffic areas.
Frequently Asked Questions (FAQ)
FAQ
It’s a fabric made of synthetic woven jute. It’s durable and ideal for sound insulation. The backing technique is common in rugs designed for high foot traffic areas. It has a latex coating on both the primary and secondary backing.
Jute is a natural fiber extracted from the fibrous jute plant. The fibers are shredded and then turned into yarn. Woven jute backing is soft and durable. It doesn’t have a non-skid texture, so placing a rug pad underneath is best.
Latex is the most common carpet backing. It’s inexpensive, easy to install, and has a solid tuft bind with high standard edge-ravel strength. Latex is easier to stretch, making it ideal for various carpet patterns.
Most residential carpets have a pad with a thickness of between 3⁄8 and 7⁄16 of an inch. High-profile carpets should also have at least a 6-pound density rating. Low-profile should have padding thickness below 7⁄16 of an inch.
