Polyester ribbon and ribbon are two kinds of fabric, which have different characteristics and uses. Polyester belt, also called polyester silk belt, is refers to the high-density polyester satin ribbon, making the yarn count high density, feel is exquisite, is very thick, smooth, ribbon means normal quality ribbons, also called general quality ribbons, the root of the number of yarn count is relatively sparse, feel is not so good polyester belt, but the price is much cheaper, if want to reduce costs, Plain ribbon is the best choice.
The ribbon is made of interwoven warp and weft, and the quality can be improved by doubling the weft, or by doubling the warp. This process is called satin structure. By doubling the warp, the fabric becomes soft and smooth. However, when the warp yarn is doubled, the density is too large, the weft yarn cannot express the pattern well, and the underside color cannot be made very flexible, and certain color requirements can only be displayed through the following process. A machine is set to do flat or ribbon surface, is generally relatively fixed, cutting ribbon width is generally not more than 10.8cm, weaving width is generally not more than 5.0cm.
Polyester has strong silk-like feeling, bright luster, but not soft enough. It has the effect of flash. It feels smooth, smooth and elastic. It is not easy to break the warp and weft after dipping into water. Polyamide gloss is dim, the surface is like a layer of wax feeling, color is not bright. Feel stiff, hand pinched fabric after release, crease, can slowly restore to original state. Warp and weft yarn fastness.
POLYESTER. Features are good air permeability and moisture removal. There are strong acid and alkali resistance, anti-ultraviolet ability. Nylon -- Nylon is also called Nylon, polyamide fiber. Advantages are high strength, high wear resistance, high chemical resistance and good deformation resistance, aging resistance. The disadvantage is that it feels hard.
Polyester properties: high strength, short fiber strength of 2.6-5.7cN/dtex, high strength fiber strength of 5.6-8.0cN/dtex. Because of its low hygroscopicity, its wet strength is basically the same as dry strength. Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber, good elasticity. Elasticity is close to wool, and when elongated by 5%-6%, it recovers almost completely. Wrinkle resistance over other fibers, that is, the fabric does not wrinkle, good dimensional stability. The elastic modulus is 22-141CN /dtex, 2-3 times higher than nylon. Good water imbibition, good abrasion resistance, wear resistance after wear the best nylon, better than other natural fiber and synthetic fiber, light fastness after acrylic, corrosion resistant, resistant to bleach, oxidant, hydrocarbons, ketones, petroleum products and inorganic acid, dilute alkali resistant, not afraid of mildew, but hot alkali can make its decomposition, poor dyeing.
Polyester fabric has poor hygroscopicity, which makes it hot and stuffy to wear. At the same time, it is easy to bring static electricity and dirt, which affects aesthetics and comfort. However, it is very easy to dry after washing, and the wet strength almost does not decrease, no deformation, and has good washable performance. Polyester is the fabric with the best heat resistance, melting point at 260℃, ironing temperature at 180℃. Thermoplastic, pleated skirt can be made, pleated durable. At the same time, polyester fabric has poor fusible resistance and is easy to form holes when exposed to soot and Mars.
Therefore, when wearing should try to avoid cigarette butts, sparks and other contact. Besides acrylic fiber, polyester fabric has better light resistance than natural fiber fabric. In particular, the sun resistance behind glass is very good, almost as good as acrylic fiber. Polyester fabric has good chemical resistance. Acid, alkali to its damage degree is not big, at the same time not afraid of mold, moth. Polyester fabric has good crease resistance and shape retention, so it is suitable for outerwear.
