1. Hollow fiber:
Common man-made fibers are polyester, polypropylene, acrylic, cotton (nylon), etc. The most common is polyester fiber. A fiber with a cavity in the cross section is called a hollow (porous) fiber, a four-hole fiber is called a four-hole fiber, and so on. Winter fillers are commonly found in hollow fibers such as seven-hole and nine-hole. This allows the cover to be moderately bulky and has good fit. The crimp of the fiber has two-dimensional curl and three-dimensional curl, the former being wavy and the latter being spiral. Advantages of polyester fiber: good warm and fluffy performance, because the air in the cavity plays a good role of heat insulation and fluffiness, and the synthetic fiber lacks the conditions for bacterial growth, so it will not be moldy, and then the price is low. Filler for home textile products.
2, cashmere and wool:
Cashmere: It is a thin layer of fine velvet that grows on the outer skin of the goat and hides in the roots of the goat's hair. It grows out when it is cold in winter, resists the cold, and falls off after the spring turns warm, naturally adapting to the climate. Cashmere, also known as cashmere, has excellent properties such as fine, light, soft, slippery and warm. It is a high-grade, valuable textile raw material. Because of its low yield, high quality and high fiber raw materials, it is also known as gold fiber, which is also called gold filler. The warmth of cashmere is 1.5-2 times that of wool.
Wool: Density is lighter than hemp and cotton, and close to silk. Its thermal conductivity is similar to that of silk fiber, and it is smaller than other fibers, so it has good heat retention. It has strong moisture absorption and is also called a fiber that can breathe.
The best variety of wool is Australian wool (abbreviated as Australian wool), which is recognized as the most white, pure and high quality wool in the world. It is the treasure of natural fiber. Australia is the country with the highest wool production. The wool is fine and uniform, and the hair is long and tidy. It is generally 7.5-8.5 cm long and curls positive.

Often, high strength, good gloss, less impurities, strong moisture absorption, is an excellent raw material for fine textiles, and also one of the excellent fillers.
What is the difference between cashmere and wool: cashmere is different from wool, wool is grown on sheep, and cashmere grows only on goats. Generally speaking, cashmere refers only to cashmere. Sheep does not have cashmere. Many people refer to the sheep's wool, which is somewhat cashmere-like, as "sheep cashmere". In fact, it is a concept that confuses cashmere and wool.
3, silk:
Silk is an animal protein rich in 18 essential amino acids. Serine has the function of nourishing the skin and preventing skin aging. It can enhance the vitality of the surface cells and promote the metabolism of the skin. Silk is a poor conductor of "hot" and has strong thermal and hygroscopic properties. The silk made of 100% natural silk is soft and warm, and it is durable and has the lightest burden on the cardiovascular system. It can effectively prevent moisture from invading the bones, prevent the invasion of harmful gases and bacteria, and enhance the activity of surface cells. health benefits.
The silk is degreased by advanced technology, and the inner tube is not easy to cake. The novel structure is greatly improved, which eliminates the trouble that the traditional silk is required to be dismantled every year. The silk is hollow, loose, uniform, and net, and the uniform and orderly internal structure makes it excellent for warmth, breathability, and suppleness.
This kind of product is an excellent traditional product in China. It has formed a mature production process as early as the Ming Dynasty. It is now produced by scientific water flow technology. Once it is listed, it has been favored by domestic, Taiwan, Hong Kong and Macao countries and Western Europe, and exported to Japan, Australia, the United States, Canada and other countries. It is the best choice for domestic and foreign wealthy bedding.
4, down:
Down and down, down, and goose down, whether it is goose down or duck down, is commonly referred to as down. Down products are the lightest air-filled fillings in the world. They are soft, fluffy and warm. The large amount of feathers of the feathers are in close contact to form a hollow layer with good thermal insulation properties. Down can absorb moisture, and the down core and related fabrics can gradually accumulate moisture and dissipate into the air. When used, it can maintain proper temperature and humidity, keep dry and prevent heat, and it is a good product.
Down is the lightest and warmest air-filled filler. The innate advantage of down is that its fibers are three-dimensional, soft and elastic, and have the best bulk. In addition, the down-filled down-filled fiber can form an air flow with the expansion and compression of the quilt, which can lead to human sweat and inhale fresh air, making the body exceptionally dry and comfortable.
Precautions for selecting a duvet should be relaxed and flattened, pressed by hand, and then released to see if the quilt rebounded and returned to its original shape. If the resilience is weak, the quality of the down is poor; the hand feels soft and feels soft. The degree, such as soft and complete small pieces, is an authentic product. If there is a long and thick long hair piece, the difference in resilience is poor quality down; violently beat the product to see if there is dust overflow, such as no dust overflow It is a good product; if you use a hand to rub the product, if you have a plush, you can use the fabric to prevent the feather cloth; use the nose to close the duvet to take a deep breath several times to see if there is any smell, no smell is good;掂 Down weight, while watching the size, light weight, the larger the volume is the best, the volume is more than twice the size of cotton.
