We have included answers to some frequently asked questions related to silk. Hope these clear your doubts. Comment below what method you used. Let us know if we missed something.

Silk is incredibly soft with a pearlescent sheen, giving it a high-end and luxurious appeal. The color of the fabric should change slightly depending on how you’re holding it against a source of light.

The most effective way to distinguish between silk and polyester is to watch them under light. If you watch silk, you can see subtle shine on it, and the luster will change color depending on the angle. On the other hand, synthetic polyester shines white under light. One can perform a burn test to confirm the authenticity.
  • First examine the fabric, look out for pearlescent sheen (the color of the shine will change slightly depending on how you hold it against light).
  • Consider the weight and price of the saree. A pure silk saree is usually ten times more expensive than artificial/synthetic ones.
  • Spun silk costs around ₹ 4500/- per kilogram. So, if your saree costs less than that, you need to check the authenticity.
  • Also, you can perform the burn test on the saree but remember to extract a loose thread in such a manner so that it does not ruin it.
  • Silk, although delicate develops far less wrinkles than other fabrics. Even if does, the wrinkles are easy to remove.  A hair dryer, steamer or an iron can come in handy to turn your clothing wrinkle-free.
  • Use an iron on the low setting to avoid damaging it. Cover the silk with cotton sheet/fabric rather than directly ironing it.
  • A hand-held steamer or a steam iron can be safely used to remove wrinkles from silk. Just keep the source of steam about 6 inches away from the fabric and move from top to bottom. The steam should loosen the fibers and render it wrinkle free.
  • Use a combination of fine mist spray bottle and hair dryer on the wrinkled area. Remember not to wet the area more than necessary, as drying will take time. Hot air will dry the area and remove the creases. If you are not sure of how hot the air will be, you can simply switch off the heating filament and blow normal air to dry the fabric.
All these methods involve water and heat, be sure not to overdo anything to avoid damaging or staining the fabric with water.
Follow the instructions on the care label of the garment.
  • Professional Dry Cleaning is recommended for most of the garments but one can easily wash silk at home if the stain is light to moderate.
  • Silk colors can often bleed. Perform a color fastness test using a cotton swab dipped in liquid detergent. Dab the swab on hidden seams to see if any dye comes off. Bright prints and colors that bleed should be dry cleaned.
  • For Washing: Fill a tub or sink with cold water and add a small amount of delicate-friendly liquid detergent. Lightly agitate for 2-3 minutes and rinse well. Continuous rubbing of a single spot can cause color lightening. Washing the entire garment is advised.
  • After rinsing, squeeze the excess water. Never twist or wring out silk garments/fabric, doing so can damage the fabric.
  • Avoid the dryer and lay wet silk garments under shade onto a clean, absorbent towels to get rid of excess moisture. Use multiple towels and then lay flat on a drying rack of towel.
  • If fabric care labels say the garment can be ironed, then iron on a low setting while the garments are still damp.
