Why is cellulose triacetate more hydrophobic than cellulose acetate?
I think it is because the steric hindrance casued by the ester groups, which are more in cellulose triacetate
Is triacetin similar to glycerin?
Triacetin is glycerol triacetate - an ester made from acetic acid (vinegar) and glycerin. So they are similar in that glycerin is used to make triacetin. Triacetin is used in foods as a humectant - it keeps them moist. Glycerin does the same, however it is also slightly sweeter.
What is triacetin used for?
Triacetin ( 1,2,3-triacetoxypropane or 1,2,3-Propanetriol triacetate or glycerin triacetate) is a food additive and an antifungal agent. It has many other uses, among them as an antiknock agent in fuel, a viscosity improver in biodiesel, a solvent in flavorings. It can be found in some tablet medicines as well.

Is acrylic a synthetic fiber?
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. To be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. The Dupont Corporation created the first acrylic fibers in 1941 and trademarked them under the name Orlon

How do you make triacetate?
Triacetate is a synthetic cellulose-based material made by acetylating cellulose with acetic anhydride to create a cellulose triacetate. This process involves combining cellulose with acetic anhydride under controlled conditions to achieve the desired degree of acetylation, typically resulting in a highly durable and wrinkle-resistant material used in textiles and film.
What does the fabric abbreviation T in Europe stands for?
There are no fabric abbreviations with just 'T'. There is 'TA' (triacetate) and 'TR' (textile residues).
What is the speed of sound in cellulose tri acetate?
The speed of sound in cellulose triacetate is approximately 2100 m/s.
What are track suits typically made from?
Tracksuits are made with synthetic fibers. It is manufactured with a combination of cellulose triacetate and polyester. There are also track suits that are waterproof and coated in nylon or PVC.
Can you machine wash a dress that is 85 percent triacetate 15 percent nylon?
You can but only on a very delicate cycle with warm to cool water. It may shrink a little but it should stretch back out with a little steam.

How do you remove nailpolish from a shirt without ruining the shirt?
