All Properties of Silk Fiber in Textile
What is Silk Fiber in Textile?
For three thousand years, China held a monopoly in the silk industry. Then sericulture – as silk production is called-spread to Japan via Korea. Gradually, silk production spread westwards over Asia. Many tales are told of the ways in which the eggs of the silkworm and the seeds of the mulberry tree on which it fed were smuggled from one country to another. According to legend, they were carried to India by a princess who concealed them in her head-dress.
In textile industry, silk are classified into below two types:
- Cultivated silk,
- Wild silk.
Cultivated silk is better than wild silk.
Physical Properties of Silk Fiber in Textile Industry:
The major physical characteristics of silk fiber have described in the following with their explanations:
Silk fiber length varies from 400 to 700 meters.
Silk is a very fine fiber. Its fineness varies from 11 to 12 microns.
Its cross-section is triangular.
Strength of silk fiber is reasonably good. Its tenacity varies from 2.4 to 5.1 gram per denier.
5. Stretch and Elasticity:
Extensibility is 15% when at break. Recovery from stretch is 90% when extension is up to 2%.
Resiliency of silk fiber is moderate.
7. Abrasion Resistance:
Its abrasion resistance is reasonably good.
8. Moisture Regain:
Moisture regain of silk fiber is 11%.
9. Biological Properties:
Normally, silk fiber is unaffected by fungus, moths and insects.
Its burn slowly when contact with flame. Silk fiber also self-extinguishes.
11. Electrical and Thermal Conductivity:
Heat and current flow rate is low.
Chemical Properties of Silk Fiber in Textile:
All the chemical characteristics of silk fiber have explained in the below:
1. Effect of Bleaches:
Damages by the effects of strong bleaching agents. Hence, perfectly while silk fabric is not seen.
2. Effect of Acid and Alkali:
Strong mineral acid damages silk fiber and strong alkali also damages silk.
3. Effect of Organic Solvent:
Silk is unaffected by the organic solvent hence dry cleaning is safe.
Dyeing at low temperature by direct, acid, basic, vat and reactive dyes could be done.
There are so many uses of silk fiber in textile and apparel manufacturing industry. Silk fiber is widely used all over the world. It is used for children’s wear, ladies wears, tie, suits etc. purposes.
