The concept of cotton and chemical fiber
Cotton (Malvaceae Gossypium): Cotton is the seed fiber of the Malvaceae Gossypium plant and is native to the subtropics. The plant is shrubby and can grow to 6 meters high when cultivated in tropical areas, usually 1 to 2 meters. The flowers are milky white, turn to deep red soon after blooming and then wither, leaving small green capsules, called cotton bolls. There are cottonseeds inside the cotton bolls. The fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the cotton bolls mature, they split open, revealing the soft fibers. The fiber is white or white with yellow, about 2 to 4 cm (0.75-1.5 inches) long, and contains about 87-90% cellulose, 5-8% water, and 4-6% other substances.
Chemical fiber (natural polymer compound):
Have a look
Pure cotton fabrics are not “perfect”. Use both hands to flatten the fabric and apply a certain amount of tension. The fabric and body should be at a 45-degree angle. Check the finish source to see if there is any dazzling flash. If so, If there is, it proves that there are chemical fibers.
Second touch
Pure cotton fabric feels full, thick, and more comfortable to the touch, while chemical fiber workwear feels slippery. For fabrics that appear to be of the same thickness, pure cotton feels firm and sinewy, while chemical fiber is soft, loose, and without sinews.
Sanshao
Cotton fiber does not melt or shrink when it is close to the flame. It burns immediately when it comes into contact with the flame. It smells like burning paper when it burns. After burning, it turns into fluffy ashes without coke. However, chemical fiber melts and shrinks when it comes into contact with the flame. The flame burns while melting, and becomes granular when leaving the flame.
Four pinches
Pure cotton has obvious wrinkles after being pinched. When the fabric is folded in half and stretched with fingernails, there is a clear fold line. However, chemical fiber fabrics have no wrinkles after being pinched.
Expand your thinking:
Cotton: Cotton is a traditional quilt filling. It is a traditional quilt variety. It is naturally soft, non-irritating to skin contact, has no odor, no pollution, no bleaching and dyeing, and no any The characteristics of additives make it popular among consumers. It is a traditional quilt in my country. Quilts with a high usage ratio have good hygroscopicity and warmth retention properties, and the price of cotton quilts is relatively affordable.
Chemical fiber: This is what we often call fiber quilts. The interior is filled with man-made fibers. Common ones include polyester, polypropylene, polyacrylonitrile fiber, cotton fiber, etc. The fiber has good thermal insulation and loosening properties, because the air in the cavity plays a good role in heat insulation and loosening. Other synthetic fibers lack conditions for bacterial growth, so they will not become moldy or moth-eaten. Moreover, they are cheap and are widely used in home textiles. Product filler.
Silk: It is an animal protein, rich in 18 kinds of amino acids necessary for the human body. Among them, serine has the function of nourishing the skin and preventing skin aging. It can enhance the vitality of body surface cells and promote skin metabolism. The silk has been degreased through advanced technology, and the inner tube is not easy to cake. The novel grid structure greatly improves its integrity, eliminating the trouble of having to dismantle the traditional four-fold tube every year. The silk quilt’s hollow, loose, even and clean silk body shape and uniform and orderly internal structure make it have excellent performance in terms of warmth retention, breathability, meat order and other bedding properties.
Wool: The density is lighter than linen and cotton, and similar to silk. Its thermal conductivity is similar to silk fiber and smaller than other fibers, so it has good warmth retention. It has strong moisture absorption and wicking properties, and is also called a breathable fiber. The best variety of wool is Australian wool, which is recognized as snow-white, pure and high-quality wool and is a treasure of natural fibers. It has high strength, good gloss, few impurities and good hygroscopicity. It is an excellent raw material for fine fabrics and one of the excellent fillers.
Down: Common down is divided into duck down and goose down. It is a light filling filled with air. It is soft, loose and warm. The large amounts of down of the feathers are in close contact to form a hollow layer, which has good Insulation properties. The innate advantage of down is that its fibers are stationary, soft and elastic, and have good looseness. The down fiber with excellent elasticity can form air flow as the quilt expands and compresses, which can lead to the human body’s sweat and inhale fresh air, making the human body particularly dry and comfortable.
