What is the meaning of the nine holes? Can the nine holes be washed?
What is the meaning of nine holes? Can nine holes be washed? I often hear people say "seven holes" and "nine holes". What exactly does this "seven holes" and "nine holes" mean? It turns out that this is a different classification of "fibers." Fiber is also known as "space cotton" and is made of polyester, rayon, etc. "Hole" refers to the hollow core of a fiber. The number in front of the hole indicates the number of hollow cores used. . The fibers on the market are mainly divided into four holes, seven holes and nine holes. The quality evaluation is generally divided by the number of holes. The more the number of holes, the higher the gas permeability and the better the quality.
Scientific understanding of the concept of seven-hole nine-hole cotton:
The so-called "seven-hole cotton" and "nine-hole cotton" are actually chemical fibers. The inner core of the quilt with holes is not cotton, but a chemical fiber product. The country currently has no standard for long and short pillows, and there is no specific requirement for the content of porous fibers. It is said that the actual content is 0%, or 10% to 100% can be called seven-hole or nine-hole pillows, and the market even appears. 11 holes, 12 holes pillow. "Seven-hole cotton" and "nine-hole cotton", in fact, these products should be called "polyester fiber" and "cotton" do not touch the edge. Regarding the number of so-called "holes", it is impossible to study. The "Pillow Memories" quotes the introduction of the Chinese fiber industry's authoritative Yizheng chemical fiber. At present, the most advanced Yizheng chemical fiber factory only produces one hole of hollow fiber, and there are no seven holes or nine holes. Fiber, most of the seven-hole or nine-hole fibers on the market are hollow cotton.
B, then look at the content of the purchase of nine holes, first look at the content of nine holes in the quilt. Although some of the logos are nine-hole cotton quilts, the nine-hole cotton inside is not 100%, but only accounts for a certain proportion. At present, the relevant departments have not yet set standards. Only when the proportion of nine-hole cotton accounts for a large proportion can be called nine-hole quilts. Therefore, consumers must clearly see the content of nine-hole cotton when purchasing. You should purchase a nine-hole quilt with a nine-hole cotton content of 100%, so that the quality is more stable.
C pay attention to the season to buy seven holes is not the same as the usual cotton used, do not have to look at four pounds, or six pounds, or even eight pounds, nine holes are generally around three pounds, buy seven The standard of the hole is divided according to the season of use: winter quilt, spring and autumn, or air conditioning. Winter is generally applied to indoor temperature of 4-12 ° C, spring and autumn is applied to indoor temperature of 12-22 ° C, air conditioning is applicable to indoor temperature of above 22 ° C.
D When you look at the quilt fabric, you should first take out the quilt and see if the fabric of the quilt is cotton with high count and the fabric is tight. Because the fabric is tight, it can be guaranteed that the chemical fiber filler inside the quilt will not escape. At the same time, you can touch it by hand, whether the quilt looks very soft and smooth. A good quilt should be very slippery. Once released, it will naturally return to its original state. If you feel a little sticky, it means that the fiber filler is not 100% nine-hole fiber, or the quality of the seven-hole fiber is very poor.
E Don't ignore the stitches and then tiling the quilts to see if the whole is flat, to see if the thickness is even, especially if you want to see if the four sides of the quilt are natural and straight. After looking at the whole, look at the seams. Look at the straightness first, then look at the unevenness of the line. It is best to measure it with a hand. There is a few needles in a tiger's mouth. Then change the amount and see if it is still the number of stitches. A good quilt should be straight and stitched. The stitches are the same. Here are a few stitches.
