Side by side comparison, a poorly produced vinyl fabric will 'look' the same as a highly engineered version.
A known idiom reminds us not to be 'penny wise, pound foolish' and in almost any purchase or specification decision we can easily get seduced by a lower price and not fully realise the actual cost. We have all experienced this in one form or another, but is this apparent in a fabric specification decision? Surely fabric is fabric?
how the temperature needs to be adjusted to 80℃ to allow drying of various solvents which need to evaporate.
Not correctly managing any of these steps can have dramatic effects on the end product. Unfortunately, to look at the product, even in a side by side comparison, a poorly produced vinyl fabric will 'look' the same as a highly engineered version. The difference only becomes apparent after some use.
These fabrics contain a knitted base fabric, a polyurethane foam middle layer and a wear-resistant top coat…The composite is then foamed, cross-linked, and laminated to a textile base…An important requirement of the upholstery fabric is that it should have proper flame-retardant additive to reduce the ignitability of the products.
Additional ingredients can also be added to improve the fabrics performance. For instance UV (ultraviolet) stabilisers can also be added to protect the fabric in direct sunlight. Again, from looking at a highly engineered fabric, compared to a poor grade one, there is no way of knowing if the product has UV stabilisers included and again this will not be known until the fabric starts to fade or flake after exposure to sunlight.
Upholstery-grade cloth has a thick foam layer ranging from 360 to 480 grams per meter squared, a top layer of 180 to 360 grams per meter squared.
Producing vinyl fabric below these tolerances, which is common practice in cheaper grade vinyls, will naturally result in an inferior product, yet may remain unknown to the buyer. Typically, cheaper vinyl manufacturers use less expensive 'fillers' and as Sen further points out, 'the primary role of a filler in PVC is reduction in cost'. Extensive use of filler in the production of a fabric will again have no initial visual indication.
Again, performance would only become apparent when in situ.
One major furniture store in the UK, DFS, came under heavy criticism for supplying poor quality furniture recently. The knock on effect was damage to the DFS brand and an investigation by BBC TV who pointed out that due to the poor quality fabric being used in their leather and faux leather sofas, they failed the necessary standards for UK fire safety regulations and were therefore shown as illegal for sale in the UK. Secondary costs such as the re-upholstery and transport are never factored in along with the damage caused to the brand and negative publicity generated. As a specifier, supplier or manufacturer of furniture, is it worth the risk? If you visit a restaurant, store or office and notice poor quality upholstered furniture where the colour is fading, rubbing off or the material is flaking, what impression does this create? What does this communicate about the organisation or brand?
having to absorb the additional cost of having to collect, transport, re-upholstery and re-deliver.
All of which epitomises 'penny wise, pound foolish'.
