Problem one: How to know if a product is lint-free
Many distributors and end-users are understandably confused about what products
are lint free and which ones are not. Some cloths are advertised as being ‘low lint’,
without it being clear what is meant by this. Our grading system goes a long way to
addressing this issue, so customers always know how much lint they can expect to find
on their rags.
Lint-free cloth is any type of cleaning cloth that does not give off any fluff or fibres
For cleaners who wanted to avoid lint, the simplest solution was to steer clear of
fabric rags altogether. As alternatives, they could turn to chamois leather, gauze or
cheesecloth. The disadvantage of these was the expense: unit for unit they were many
times more costly than traditional rags. Nylon treatment would also reduce lint in
cleaning cloths, but this would make the rag unsuitable for use with some detergents.
Fortunately, manufacturers can now produce high-quality lint-free cotton wipers,
through a production process known as microfiber weaving. These microfiber rags are
woven together in such a way that short strands do not detach when they are used or
exposed to heat. They also create a variegated cleaning surface that is more effective
at removing stains and dirt with less dependence on detergents.
All our 100% cotton wipers have a very low lint content, including our roller towels,
white linen and white sheet cleaning rags.
Problem Two: How To Ensure Your Wipers Are Metal Free
The second largest problem people experience with cleaning rags is metal. It may
surprise some people that your average cleaning rag has any metal content at all, but
this is unfortunately the case.
The problem with metal…
The problem with metal is that any metallic particle can scratch a surface. In hygienic
environments, this creates a big issue, as microscopic surface scratches become havens
for bacteria that are very difficult to clean. For surfaces that need painting, scratches
also make it difficult to achieve an even paint job.
The presence of metal also increases the risk of fire through sparks, and in extreme
cases metal shards can cause injury by puncturing the skin. The presence of metal is
therefore something that manufacturers take pains to avoid.
How metal gets into some wipers
Cleaning rags are frequently made from recycled fabric, including human clothing.
When clothing is processed for recycling, spot checks are carried out to remove zips,
buttons and pins – which are the most common forms of metal found in clothes.
However, many manufacturers rely on the human eye to detect and remove metal
components, thus introducing an element of human error. This is how metal fragments
make their way into cleaning rags.
Avoiding metal contamination
How to ensure these metal fragments don’t find their way onto the finished products?
The only way to be sure is to put them through a metal detecting machine. In our
factory the Smartora rags are placed on a conveyor and sent through a sensitive metal
detector. Any wipers with metal in them are then automatically cast to one side. It
is a simple but effective way of an extra safe guard that none of our products are
contaminated by metal shards.
Our metal detected rags stand out from the crowd, the inline food grade metal detection unit is the only one in Europe used in the textile wiper industry.
