How to identify quilt fabrics:
Appearance test
The regular silk was examined and the silk inside was clearly visible after the test was opened. The regular silk is not quilted, and only the four corners of the quilt and the quilt are stitched with the needle to avoid the silk slip; now some manufacturers use the quilting for the silk quilt with poor quality or adulterated silk, and the whole quilt will be quilted , so that consumers can not check the filler inside, this time consumers should pay attention.
Touch test
The surface of high-quality silk has a soft, pearl-like color, is neither black nor astringent, and the color of the silk is uniform and evenly diffused to the light without fluorescent reflection; the hand feels soft and delicate, smooth, and long and elastic. Mulberry silk is whiter in color than tussah silk, and its fiber is longer. It has a softer, more delicate, smoother and more elastic feel. The silkworm flower brand uses 100% natural double palace silk, which is longer, finer, smoother, and more flexible than the silk of ordinary silk. Therefore, it can promise long-term free removal.
Combustion test
Feel free to pull out a few wires and burn it with a lighter: The burning point of the silk is very low, it won't burn, and it will burn off soon after burning. The smoke that comes out when burning is white, and it is accompanied by the smell of protein burned by burning hair. (The odor of charred animal protein in hair or feathers). The burning ash is lightly kneaded into a black powder; the chemical fiber material will burn, burning and emitting black smoke with a pungent odor. The ash will be black and pinch and become hard and small. There is a clear difference between the two.
