In our previous post, we learned about What is Acetate Fiber and its Characteristics. In this article, we will learn the Properties of Acetate Fiber.
Physical Properties Of Acetate Fiber
- Acetate filament: It is in broken strands. The length relies on the capacity of the winding mechanism. Modern winders hold many pounds of yarns with one or two knots per cone.
- Acetate staple fiber: It can be cut into the desired length. Commonly desired lengths are 1.50, 2, 2.50, and 3 inches tall 7 inches for silk industries.
- Fineness: The diameter of the strand ranges from 1.5 to 4.1 deniers for filaments and 1.5 to 20 deniers for staple fibers.
- Appearance and Color: The luster and color may be as desired. Bright luster may be received by lesser twist. The staple is not as lustrous as filaments. Various shades from paler tints to heavy may be acquired as they are the whitest fibers.
- Density: The density ranges from 1.25 to 1.33 gm per cc. relying on the methods of measurement and moisture at the time of making.
- Absorption: The hygroscopicity is corresponding to cellulose but absorption is much less since hydroxyl groups are removed by acetyl groups.
- Tenacity: The wet strength is 65% of dry strength. The fibers can be changed in tenacity by the manufacturers.
- Elasticity: Under general situations, elastic recovery of fiber is completed within a few seconds. But for a longer time and heavier load creep, deterioration or clearage occurs.
- Thermal properties: It is a thermoplastic material. With temperature it becomes soft. It can be ironed at a temperature up to 2500 F. Above this sticking and melting occur.
- Conductivity: It is a perfect insulator. The static electricity is created by friction.
Chemical Properties Of Acetate Fiber
- Effect of alkalis: It is stable to water even at a boil and can withstand soap solutions and alkalis at normal temperatures.
- Effect of acids: It is unaffected by a thin solution but is attacked by strong acids. The degradation of molecules occurs and the chain breaks.
- Effect of oxidizing agents: Mild oxidizing agents may be utilized i.e. chlorine is old and mild peroxide.
- Effect of organisms: It is resistant to attack by bacteria and mildew but it is attacked by the moth which makes holes in the fabric.
