Flax (Linen) is more difficult to bleach than cotton due to its high amount of impurities, such as pectin and gum. Weak acids have no effect on linen, but concentrated acids can damage it. Linen has good resistance to alkaline solutions. The following are the advantages, disadvantages and application scenarios of Chemical Properties of Linen Fiber:
1.High strength: Linen fiber has natural strength and durability, and chemically treated for greater strength.
2.Good antibacterial properties: Linen fiber has natural antibacterial properties. For those who are sensitive to bacteria, it is a good choice.
3.Absorbent: linen fiber is very absorbent, able to absorb large amounts of water, and dry quickly.
1.Susceptible to chemicals: linen fiber is easily damaged by strong acids, strong alkalis and other chemicals.
2.Prone to yellowing: linen fiber is susceptible to sunlight and oxidation in the air, thus turning yellow
- Textiles: Linen fiber can be used to make high-grade fabrics, such as linen skirts, bed sheets, curtains, etc.
- Industry: linen fiber can be used to make a variety of industrial supplies, such as rope, canvas, wire rope, etc.
In general, the chemical properties of linen fiber make it in the manufacture of high-grade fabrics and a variety of industrial supplies have a wide range of application prospects. However, attention needs to be paid to its storage and use in the process is susceptible to the effects of chemicals and oxidation
What is the chemical composition of linen fiber?
A flax fiber is composed of cellulose (70-85%), hemicelluloses (11-20%), pectin (2-12%), and lignin (about 2%), along with some minor extractives such as fat, wax, protein, tannins, dyes, and inorganic salts.
What are physical properties of linen?
The strength of flax fiber is attributed to its highly crystalline polymer system, which allows for longer polymers to form more hydrogen bonds than cotton polymers. Interestingly, flax is one of the few fibers that become stronger when wet.
What is the chemical test of linen?
Linen is a type of fabric made from natural plant fibers, and when burned, it produces ash with a slight wood odor. On the other hand, synthetic fibers will melt and form a blob when burned. Additionally, pure linen has a distinct texture and weight that can be easily identified.
