The weather is getting colder, and the quilts with seven holes and nine holes are more and more popular with the public. However, the recent Japanese newspaper 84499000 news hotline received a call from an enthusiastic reader. The reader reported that because the country does not have any relevant specifications for this "hole" quilt, many seven-hole quilts and nine holes are now on the market. All are stupid, and the name is not true.
The reader stated that he worked in a factory that produces quilts and knew the inside story. He said that the four-hole filler is a four-hole fiber, and four holes are uniformly distributed in the cross section of the fiber; the nine-hole filler is a nine-hole fiber, that is, nine holes in the cross section of the fiber. Shaped like a dragonfly. “In general, the more holes, the better the softness and comfort of the quilt, the better the temperature and the higher the price. However, in order to reduce the cost, the manufacturer clearly marks the nine-hole quilt, and the filling may only be A small amount of nine-hole fibers, most of which are other types of fibers," he said.
Yesterday, the reporter came to a big market in Nanjing Chengdong. In front of the counter selling bedding, a middle-aged woman was picking a quilt. A female salesperson kept talking enthusiastically. "This quilt is nine holes, we This year, the quilt is sold well, 160 yuan a bed, not expensive, can sell several beds every day. If you sincerely want to buy, you can give you another 10% off."
In the corner of the quilt, the reporter found the trademark of the nine-hole quilt, indicating that the filler is “nine-hole fiberâ€, but the content is not explained. "How much is the content of the nine-hole fiber in this quilt?" asked the reporter. "You see that only nine holes of fiber are included in the filler, and the content is of course 100%." ​​The salesperson replied.
The reporter took a little filler from the side of the quilt and went to the Jiangsu Province Fiber Testing Institute for identification. Li Hui, the deputy chief engineer of the institute, checked the fillers for the reporter. “Under the microscope, most of the fibers in the samples are solid. The content of the nine-hole fiber is very small. There are some three-hole and four-hole fibers in the middle, and the holes are very small.†Li Hui said, fiber The difference between the small hole and the solid fiber is not large, and the quilt is not very different from the quilt of the common chemical fiber.
According to an industry insider, there is no mandatory standard for the fiber content of the hole in the hole in the country. That is to say, a quilt containing only 1% of the nine-hole fiber can also be called a nine-hole quilt. If the filler is made of 100% nine-hole fiber, then the winter price of a double cotton fabric is at least three or four hundred yuan. For the time being, the price of the nine holes on the market is basically 100-300 yuan. It can be said that almost all the nine holes in the market are not filled with 100% nine-hole fiber. As for the "ten hole quilt" introduced by some manufacturers, this is simply impossible, because the current drawing process can not reach ten holes hollow. Citizens should be cautious when choosing such perforated quilts.

• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
