Fibres that are taken from animals or animal by-products are called?
Fibres that are taken from animals or animal by-products are called protein. This is because animal fibres, such as wool, silk, and cashmere, are primarily composed of proteins.
These proteins give these fibres unique properties, such as warmth, softness, and durability. Animal fibres are highly valued in the textile industry for their natural and luxurious characteristics.
Natural fibres require longer drying times because they are?
Naturals fibers longer drying times because they are absorbent. This means that they have the ability to soak up and retain moisture. When these fibers get wet, they absorb the water, which then needs to evaporate for the fibers to dry, This process takes longer compared to fibers that are not absorbent.
Fibres that come from plants are called?
Fibres that come from plants are called cellulosic because they are made up of cellulose, which is the main component of the cell walls in plant cells. Jute is a type of cellulosic fibre, but it is not the general term for all plant fibres. Cuticle is a waxy layer on the surface of leaves and stems, not a type of plant fibre.
Protein is a macromolecule found in living organisms, not a type of plant fibre. Synthetic fibres are man-made and not derived from plants.Fibres that come from plants are called cellulosic because they are made up of cellulosic
These fibres come from plants and animals
Fibers that are absorbent and req longer dry times
Protein fibres are dissolved in a 5.25% solution of?
Protein fibres can be dissolved in a 5.25% solution of bleach. Bleach contains sodium hypochlorite, which has the ability to break down and dissolve proteins. This is why bleach is commonly used as a stain remover for protein-based stains, such as blood or grass stains.
The high concentration of bleach in the solution makes it effective in breaking down the protein fibres. Protein fibres can be dissolved in a 5.25% solution of bleach. Bleach contains sodium hypochlorite,
