With new discoveries in waterproofing properties, it has now expanded to the production of bottles, plastic transparent wrap, high quality wood finish that seals the grain and gives a high sheen, and many other products. Thus emerged the new Dacron material. It has opened up a wide range of new ideas and products for manufacturing that has triggered the imagination of people all over the world.. They discovered a way to blend ethylene glythol and terephthalic acid and condense them down to make this new material that could be turned into fibers.John Rex Whinfield was a British chemist born in 1901.Whinfield began searching for other alternatives to nylon along with his assistant, James Tennant Dickson, late in the 1930's.
They patented their new find in 1941, but there was a war going on at the time and their patent wasn't made public until 1946 because of secrecy wartime restrictions.Most likely everyone knows what polyester is.In 1941 the first patent was issued for a polyester fiber initially named Terylene or Dacron. He had been an assistant to Charles Cross and Edward Bevan who had earlier worked with viscose rayon in 1892.After his patent, ICI later took off with their own version of the Terylene, and Dupont with their own version of Dacron. But what exactly is it other than a type of fabric used for soft and comfortable bedding?
Where Medical application non-woven fabrics did it come from, how long has it been around and who discovered it?We all know the advantages of polyester. For the work of Whinfield, the University of York has honored him by naming their library in their Department of Chemistry after him in his memory. Fabrics of polyester material are highly stain resistant and for that reason have to be dyed with what is called dispersed dyes. And in 1924 he began working for Calico Printers Association in Manchester, England as a research chemist. So in the late 1930's there was an interest to find new synthetic material to exceed the qualities of nylon. The world has found multiple spin-off uses from this synthetic polyester fabric. These dyes are water insoluble and are the smallest molecules found in any dye and are the only dyes that can be used effectively.
It is hypoallergenic and a huge asset in bedding material for those who suffer from allergies. So it is also easy to care for and keep looking fresh in our over-busy society where we are looking for products that can be kept nice looking without a lot of time and effort, labor-saving products wherever we can find them. And many times it is also wrinkle resistant.So it has turned out that Whinfield has opened up a whole new realm of discovery in his quest for a better fabric. Nylon fabric was a precursor but was inferior in resilience and toughness.Not only is it used as a fabric for clothing, it is also used as bedding fabric in sheets, blankets and throws, upholstery and also used as cushioning in decorative pillows and bed pillows, down alternative comforters, as well as other padding. Polyester has properties of strength as well as water resistance and wind resistance qualities
