Well, darling, "terivoile" isn't a real word in the English language. Maybe it's a secret code word for a fabulous cocktail or a new dance move. But in the world I live in, "terivoile" is as real as a unicorn wearing a tutu.
What catalyst is used in making polyesters?
The catalyst commonly used in making polyesters is an esterification catalyst, such as an acid catalyst like sulfuric acid or an organic acid like p-toluenesulfonic acid. These catalysts help facilitate the reaction between the diol and the dicarboxylic acid to form the polyester polymer.
Who invented polyester and when and chemical formula of polyester?
Polyester was invented in the early 1940s by British chemists John Rex Whinfield and James Tennant Dickson. The chemical formula of polyester typically consists of long chains of polymers made from repeating ester units linked by glycol and diacid molecules.
Polyester is a category of polymers which contain the ester functional group in their main chain.
However! the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET), which can be made in two ways, and both are done in chambers that feature strong vacuums and high temperatures. # The first requires dimethyl terephthalate and ethylene glycol. You make it this way, and the process will liberate methanol--which you have to capture, store and figure out something to do with. (In most cases, the "something to do with it" is to mix it with terephthalic acid and feed it back into the process.) # The other is to use terephthalic acid and ethylene glycol. This requires more heat, but it produces no methanol--a very important thing when you consider how dangerous methanol is. No one wants it around if they're not using it.
Some polyesters also include naturally-occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics such as polycarbonate and polybutyrate.
What is made from 100 percent polyester?
Items like clothing, bedding, and curtains can be made from 100 percent polyester. Polyester is a synthetic material known for its durability and wrinkle resistance, making it a popular choice for a wide range of products.
Where does fiber polyester come from?
please answer this question as i really need to know by tomorrow.. :)
This guy is supremely dumb, he commented a question on a answer. He must be a dumb American.

Polyester oil is a type of synthetic oil that contains ester compounds. It is often used in high-performance and racing engines due to its ability to withstand high temperatures and provide better lubrication than traditional oils. Polyester oils are known for their resistance to oxidation and thermal breakdown.
What is a monomer of polyester?
polyester is a monomer formed of two monomers namely 1,4-butane diol & adipic acid
Polyester is a synthetic material that is inherently flame resistant, meaning it is less likely to catch fire compared to natural fibers like cotton or wool. However, if exposed to a high enough temperature, polyester can melt and burn. Treating polyester with flame retardant chemicals can further enhance its resistance to flames.
How do you fade out polyester?
To fade polyester fabric, you can try soaking it in a mixture of hot water and bleach for a short period of time. Rinse it thoroughly after soaking and repeat the process if needed. Keep in mind that excessive exposure to bleach can weaken the fabric, so it's crucial to monitor the process carefully.
Why is polyester unsuitable for dyeing and printing on?
Polyester is hydrophobic, meaning it repels water-based dyes and inks. This makes it difficult for the color to adhere to the fabric during dyeing and printing. Specialized disperse dyes and printing techniques are needed for effective color application on polyester.
Yes, polyester can be dyed using a method called disperse dyeing. This involves using specific dyes that are able to penetrate the polyester fibers. It is important to follow the dye manufacturer's instructions for best results.
Fibre or Fiber is a type material with continuous filaments and ever heard of PET, Polyester is a category of polymer, which are chemical compound, polyesters are produced in numerous forms such as fibers and sheets. Some clothing are made of polyester fibre (natural or chemical)
YES, IT IS UNCOMFTORBLE. it causes heat and static energy when using it. it feels like A TABLECLOTH!. it is only alright if it is blended with cotton or if not coloured. if your talking about shirts then it wont be much if a problem but with duvet covers then yes. you would have to use a fabric softener to soften the rough polyester. but the benefit is it wont really get dirty. dirt on polyestre can be cleaned of much easier than cotton.
Polyester is used to manufacture clothing and home furnishings such as furniture, bedspreads, sheets, pillows, carpets and curtains.
Polyester is also used to make plastic beverage bottles (PET).
Mylar, used to make Mylar balloons, is a kind of polyester film. The balloons are a composite of Mylar and aluminum.
Polyester is also used to manufacture thread, hoses, high strength ropes and much more.
What is the best type of moisture wicking clothing?
There are a varity of moisture wicking fabrics available on the market. Most of these are polyester bledns that do a better job of wicking moisture away versus original cotton. The original moiture wicking fabric was created by Dupont and is called Coolmax. Other companies have developed other fabrics such as dri-release, Underarmour and dri-fit. There are many places where you can find these products on the web. CoolClothingUSA.com offers a nice selection at a reasonable price. Use of nanoparticles in moisture wicking clothing and other products for bacterial and related odour control is extremely controversial, has been likened to asbestos and could be a serious future health hazard. Please see, for example, http://www.asbestos.net/news/could-nanoparticles-be-the-next-asbestos.html For safety it would be advisable to use moisture wicking clothing that does not incorporate nanoparticles into the technology.
The first paragraph above was obviously written as an advertisement for a particular online retailer. Caveat emptor. Do your own checking on the use of nanoparticles. No retail outlet will have a clue about this kind of issue.
What is the difference between osmoregulators and osmoconformers?
Osmoconformer adjusts to the osmotic concentration of its surrounding so that the osmoregularity is the same at the medium. Osmoconformer maintain its own osmotic concentration regarldess of the surrounding medium.
What is the difference between mycota and mycete?
"Mycota" refers to a taxonomic group that includes fungi, while "mycete" is a term used to describe individual organisms within the fungi kingdom. In essence, mycete is a specific organism, while mycota is a larger category that encompasses multiple organisms.
What is the difference between pepsin and pepsinogen?
Pepsin is a powerful protein digesting enzyme which is far too dangerous in its active form so it is released in an inactive pepsinogen form by the cell and activated only in the digestive tract where it is required to be active.
What is the difference between sequestration and chelation?
sequestration means sequeezing matrials in a non useful form to a certain area
as comlexes while chelating means canceling or pushing away things in whetever
form out side the vital pool
What is the difference between chalcedony and chert?
Chalcedony is a type of cryptocrystalline silica composed of quartz, while chert is a sedimentary rock made up of microcrystalline or cryptocrystalline quartz. Both chalcedony and chert are similar in composition but can differ in terms of color, translucency, and formation processes.
What is the difference between psychosomatic and somatization?
To somatize is to take stress and basically turn it into or express it in somatic ways. A child with separation anxiety may somatize the anxiety and express it as a stomach ache. In somatization, the stomach ache is real, but a major cause of the stomach ache is anxiety. The term "somatization" is associated with a specific disorder, which involves the occurrence of multiple physical complaints over a period of time which are believed to have more of a basis in mental health rather than in an actual physical disorder (See the Diagnostic Manual of Mental Disorders for more detail on that). The term psychosomatic is a more general term for the study of medical issues in which psychological factors play a major role. Psychosomatic medicine would include the study and treatment of, for instance, heart disease and diabetes in which psychological factors play an important role, but also other somatoform disorders (of which somatization disorder is one). such as In conversion blindness (also a somatoform disorder), the sufferer cannot see even though the brain and eye function normally. It is believed that because of psychological factors, the sufferer's exprience is that they cannot see. They are not believed to be 'faking" blindness (that would be termed "malingering if the purpose was for some sort of secondary gain like money, and it would be called "factitious disorder" if the purpose was to for primary gain like being in the sick role and receiving sympathy). In conversion blindess the sufferer really experiences themselves as blind despite the fact that the cause is psychological rather than physiological. The psychoanalytic explanation for this would be that there was something in the person's environment that they desperately do not want to see, and "blindness" is the unconscious mind's solution to the problem. In the psychosomatic study of heart disease, however, there is more of a focus on the impact of stress, anxiety, and anger on the heart and its functioning. In psychoneuroimmunology, there is a focus on the ability of certain personality traits and ways of managing stress to impact overall health and resistance to disease.
Is polyester the scientific name for plastic?
Not always, although the term is widely used for plastics such as polystyrene and polyethylene, and for artificial fibers such as Dacron, which like plastic bottles is a form of polyethylene terephthalate (PET). There are some natural polyesters.
A "polyester" is any natural or synthetic polymer (repeated chain molecule) containing esters. But the term is usually applied to two groups of synthesized molecules: thermoplastics and thermosets.
What is difference between LDPE and HDPE?
You don't specify anything to compare it to. If you mean the difference between LDPE and HDPE, then LDPE has branched chains which pack together loosely, making a softer material. HDPE is firmer because it has unbranched chains which pack together tightly.
