Vinyl Floorcovering

Background

Vinyl floorcovering is defined as either resilient vinyl sheet floorcovering or resilient vinyl tile floorcovering. Vinyl sheet floor-covering is generally available in either 6 ft (1.83 m) or 12 ft (3.66 m) widths and vinyl tiles are generally 12 x 12 in (30.48 x 30.48 cm). Sheet goods are generally retailed with no sticky backing. Thus, adhesives need to be purchased to adhere the flooring to underlayment. Vinyl tiles may be purchased dry or with a pressure-sensitive glue backing protected by a paper covering that must be removed by the installer.

Vinyl sheet flooring, particularly, varies in thickness and in manner decorated. Thinner sheet vinyl is 10-15 mils (mils are a thousandths of an inch) in thickness as opposed to longer wearing sheet vinyl (which is also more expensive) that may be 25-30 mils thick. Patterns may be printed with a rotary press (called rotogravure printing) or with large plates engraved intaglio with the design engraved below the surface of the metal. Both printing methods impress a pattern on top of the gel layer of foam and underneath the wear layer, rendering a relatively durable pattern.

These vinyl floorcoverings are preferred by many homeowners for their ease of installationmany do-it-yourselfers are able to install them with relative ease. However, vinyl sheet floorcoverings that are 25-30 mils may difficult to handle or install for the unskilled homeowner. The vinyl tiles are far easier to install and are the vinyl flooring most often installed by the home-owner. Furthermore unlike other flooring materials, sharp blades will easily cut the vinyl flooring so that it may conform to corners, cabinets, and curves.

In addition, vinyl floorcoverings may be applied over old flooring, and are easily cleaned with a vacuum or a mop with soap and warm water. To the delight of many householders, with proper care, many brands do not require waxing. Polyurethane coatings render a high-gloss finish that emulates a shiny, waxy surface and generally stays rather shiny over the years. If dulled, a special vinyl floor finish may be applied. However, vinyl floorcoverings are not as durable as ceramic tile and will have to be replaced periodically.

As with many household materials, vinyl sheet and tile flooring comes in residential grade and commercial grade. Residential vinyl flooring varies in thickness, method used for imprinting or decorating, and style. Commercial vinyl floorcoverings conform to specifications that require superior durability and stain resistance (particularly use-ful in hospital settings). Some commercial-grade vinyl floorcovering is non-slip for high public traffic areas.

History

Housewives have long known that a hard, relatively waterproof surface makes a fine floorcovering. Tamped earth mixed with ox blood dried into an easily-swept surface in primitive homes. Painted wooden floors were relatively easily maintained but had to be renewed at some effort. It was particularly troublesome keeping carpeting clean in eating areas such as dining rooms. In the early eighteenth century, floor cloths, which were large squares of fabric, were laid under dining tables to catch wayward crumbs. These floor cloths were simply taken outside and shaken free of crumbs and returned to their spot under the table.

However, later in the 1700s, someone decided that the floor cloth could be improved upon if a relatively sturdy fabric such as canvas, hemp, or linen was coated with and evaporating oil and paint and thus made waterproof. Easy to scrub and sweep, these floor oilcloths were quite an improvement over the fabric floor cloths. Better yet, these oilcloths were inexpensive and could be hand made at home or purchased mass produced later in the nineteenth century. From there it was a quick hop to linoleum which was manufactured from linseed oil, cork gums, and pigment. This leather-like floor-covering was mass produced by 1890 both in the United States and abroad.

Linoleum was tremendously popular from 1900 until after the World War II when floorcovering manufacturers sought to replace linoleum with other long-wearing fashionable, easily maintained floorcoverings. By the late 1950s, resilient floorcoverings were here at lastthese included vinyl flooring which gives slightly as one walks across it. These vinyl floorcoverings were far brighter and more colorful than linoleum because the vinyl floorcoverings were made with a clear vinyl gel which made the printed colors vibrant. As a 1960 Sears Catalog proclaimed about vinyl floorcoverings: All gloss and glowno hard work!

Raw Materials

The primary components of vinyl floorcoverings include polyvinyl chloride (or vinyl) resins, plasticizers (high molecular-weight solvents), pigments and trace stabilizers, and a carrier sheet or backing. The backing may be felt or highly filled paper made from wood pulp and calcium carbonate. High-gloss surface vinyl sheets or vinyl tiles have an additional polyurethane coating applied at the end of the process. The glue applied to the back of some vinyl tiles (to make a pressure-sensitive adhesive) is made from organic resins.

Design

The design departments of vinyl floorcovering companies are constantly seeking new inspiration for successful patterns and colors that will work in sheet and tile form. The designers work with marketing groups to determine what colors and styles will capture the public’s interest as much as five years from current production. The designs are transferred from drawing to computer, and mock-ups of the different patterns are produced in an array of colors. The designs are then printed off of the computer on full-size paper and in full color.

If a full-scale paper pattern is approved for further development, printing plates either 18 x 24 in (45.72 x 61 cm) or 24 x 36 in (61 x 91.44 cm) in size are created by engravers. These plates are then used to print samples of the pattern on undecorated flooring (called gel stock) as prototypes. The wear layer, or final, often shiny surface of the sheet flooring, is applied over the printed pattern, so the designers have a close approximation of the finished product.

The prototype is either approved as is, retooled, or dropped. The time it takes from design to market varies from as little as three months or as long as six months.
