Observe silk and record its characteristics

Hello:

There are two main types of silk produced in my country. One is commonly known as mulberry silk, which is the silk extracted from the cocoons of mulberry silkworms. This silk is white with yellow in color, feels delicate and smooth, and has a faint smell unique to animal fibers. The quilt made with this kind of silk is particularly soft and close to the body; at the same time, it also has a disadvantage: after being used for a period of time, the gaps between the silk are easy to tighten, causing the quilt to become thinner, and the filling and warming effect is not as good as before.

Another type of silk is tussah silk, which is produced from tussah cocoons. The tussah silkworm is a wild silkworm that mainly lives in the north. It is artificially raised in the wild mountain oak forests and feeds on tussah leaves. Compared with mulberry silk, tussah silk is darker in color, and its original color is gray-black. Materials of this color are usually not accepted by consumers when making quilts; therefore, in the actual production process, tussah silk often needs to be faded with acid-resisting chemicals, which is harmful to human health. In addition, tussah silk contains a lot of "sericin", which makes it feel rough, not smooth enough, and has a dull luster. Moreover, tussah silk is also relatively rigid and not very close-fitting.

Silk is a continuous long fiber formed by solidifying the silk liquid secreted by mature silkworms when they spin cocoons. It is also called "natural silk". Like wool, it is one of the earliest animal fibers used by humans. According to different foods, it is divided into mulberry silkworm, tussah silkworm, cassava silkworm, camphor silkworm, willow silkworm and celestial silkworm. The silk strands extracted from a single silkworm cocoon are called cocoon silk, which is made of two single fibers bonded and coated by sericin. The silk strips made by extracting the cocoon silk from several silkworm cocoons and wrapping them together with sericin can be divided into mulberry silk (also called raw silk) and tussah silk, collectively called silk.

Mulberry silk is a natural animal protein fiber and the main raw material for silk weaving. Smooth, soft, lustrous, warm in winter and cool in summer. It has a unique "silky sound" phenomenon when rubbed. It has good extensibility, good heat resistance, and is not resistant to salt water corrosion. It is not suitable to be bleached with chlorine. Treat with detergent or detergent.

Using mulberry silk as raw material, the filament made by wrapping several cocoon silks together and glued together is called pure silk. Real silk, including mulberry silk and pressed silk, is soft and delicate in quality and is the best

How do you answer this? The semi-finished product of mulberry silk used to make quilts - "Jin Dou" is priced at About 80 yuan per pound (sold above). Of course, the prices of mulberry silk produced in three periods are also different: spring, summer, and autumn. Spring silk is the best and most expensive, followed by autumn silk, and finally summer silk. Silk.

The price of good finished tussah silk is half of that of mulberry silk, and the price of poor quality tussah silk is less than one-third. If the price fluctuates, it is generally not very big, and it will not be as expensive as pork this year. It has doubled. If you want the price of silk brocade, it will be more than twice as expensive. For specific fluctuations, you can check the "China Cocoon Silk Trading Network"

I have bought these two kinds of quilts, and I will tell you about them. Come to experience, when it comes to keeping warm, down is the best, silk is second, when it comes to health care, silk is first, and overall, silk is better than down. Because the temperature in the city is generally not very low, down is used to make clothes, which is very warm outdoors. In the city, the two are actually about the same. (Generally, the price of silk quilts of the same brand is more than twice that of down quilts)

Mulberry silk is a natural fiber that combines lightness, softness and fineness in nature. It is known as the "second skin of the human body" "It has a reputation and is called the "Fiber Queen" by the industry. Its main component is pure natural animal protein fiber, which contains a variety of amino acids necessary for the human body. Mulberry silk is smooth, breathable, soft, moisture-absorbent, non-itchy and anti-static, making it an excellent material for making underwear. The silk quilt with mulberry silk as its inner substance has unique qualities and advantages such as close-fitting warmth, fluffy and softness, breathability and health care.

The prices of silk online are confusing because many of them are fake: 1. Those that do not contain silk at all 2. Those that use tussah silk to pretend to be mulberry silk 3. Those that use tussah silk mixed with chemical fibers.

Silk is divided into mulberry silk and tussah silk. The former is suitable for making quilts because it is soft, while the latter is relatively hard and needs to be degummed through chemical treatment. Pure natural tussah silk is not white and can only become white after chemical treatment. It is white, (profiteers use this method to pass tussah silk as mulberry silk). Let me tell you the basic cost price of mulberry silk quilts. The selling price of "jindou" used to make mulberry silk quilts is about 80 yuan per pound. If you buy 4 pounds of brocade bag to make a bed, the price of a 4 pounds of mulberry silk quilt will be at least 300 yuan. This does not include the tire cover and the price of the quilt cover. Silk quilts that cost more than 100 or 200 yuan on the Internet are basically fake. Many quilts are made of tussah silk. You can’t even recoup the cost of mulberry silk for 200 yuan, let alone make money. So if you want to buy online, it is best to find sellers who hand-make silk quilts in Tongxiang, Zhejiang. Their prices are the most reasonable and the quality is the best. Tongxiang, Zhejiang is the hometown of silk quilts in my country.

In addition to mulberry silk quilts and tussah silk quilts, silk quilts are also divided into long and short silk quilts. Among the filaments, there are mulberry silk and tussah silk. The current market price of tussah silk is 40%-60% of the price of mulberry silk.

For other short filaments, that’s not necessarily the case. The price ranges from 20% to 40% of mulberry silk.

The price also depends on the net weight of the silk.

The "rich real gold ones" you bought in Beijing only cost more than 500. The price is less than tussah silk. It won't be mulberry silk.

Silk quilts are divided into two types: mulberry silk quilts and tussah silk quilts. Among them, mulberry silk has better thermal insulation effect and is more expensive. Since the cost of mulberry silk is about 60% higher than that of tussah silk, there is a lot of confusion on the market. Collectively called silk quilts, the actual ones used are tussah silk.

"Fuli Zhenjin" is a good bedding product, especially their "Raschel" blanket, which is thick and spacious, and is extremely comfortable to cover with the quilt in the cold winter in the south. 1. Visual inspection method of hand feel

Observe from the length and uniformity of the fibers: silk fibers are thin and long (spun silk is short) and have a special luster; chemical fiber fibers are long and short fibers are short and neat. The degree is better. Analyzing from the feel and strength: silk feels moderate; viscose fiber, nylon silk, polyester silk and silk are similar. Analysis when fibers are broken by hand
