The difference between tussah silk and mulberry silk

Usually when we buy various silk products, we always ask some questions about tussah silk and mulberry silk, and we also hear the salesperson recommend to us the difference between tussah silk and mulberry silk. In fact, the first one feels soft and elastic, with even layers, and is made through different processes. The difference from silk is that it is more elastic and has better heat resistance.

The characteristic tussah silk feels soft and elastic. It has good heat resistance, with sericin attached to the outside of silk in layers, and its strength only begins to weaken when the temperature reaches 140°C. The moisture resistance is also strong, accounting for about 85%; sericin is light brown, and its strength can increase by 4% under wet conditions. Its insulation, strength, elongation, embrittlement resistance, acid and alkali resistance are better than mulberry silk. But the fabric shrinkage rate is large. Raw silk is not easy to dye.

Tussah silk textile products are the first choice for silk quilts and silk blankets because of their strong rigidity, strong acid and alkali resistance, natural color, coarse fibers and good warmth retention. Some manufacturers will use white alkali to rinse it, but the actual chemical residue is very low and does not cause any harm to humans.

The difference between silk and mulberry silk is that they each have their own strengths, and both are animal proteins that are close to human skin protein. All silk products have the advantages of good air permeability, UV protection and good moisture absorption, so they are noble textile products. The price is naturally expensive. The fiber processed from the silk threads spun by tussah silkworms when they make cocoons is called tussah silk. It is the raw material for weaving tussah silk and also has important uses in industry and national defense. Tussah silk is made up of two parallel flat monofilaments, and its main components are fibroin and sericin. Silk fibroin is white, translucent and shiny, accounting for about 85%; sericin is light brown, accounting for about 13%; in addition, there are ash, pigments, etc., accounting for about 2%. When reeling silk, silk threads from several tussah cocoons are drawn out and glued together to form tussah silk. Tussah silk feels soft and elastic, has good heat resistance, and its strength only weakens when the temperature reaches 140°C. It also has strong moisture resistance. Its insulation, strength, elongation, resistance to brittleness, acid resistance and alkali resistance are better than those of mulberry silk. However, the fabric shrinks greatly and raw silk is not easy to dye.

Mulberry silk is generally produced in the south. It is soft and smooth, elegant in color and fine in fiber. It is mainly used as clothing fabrics. Mulberry silk is artificially cultivated and delicate. Tussah silk is generally produced in the north. It has strong elongation, corrosion resistance, light resistance, moisture absorption, natural color, coarse fiber, moisture absorption and breathability, fluffy and warm, and is mainly used as silk quilts and silk carpets. Tussah silk is wild and free-range to absorb the essence of the earth, has good health care, and is elegant and luxurious.
