What is LDPE cooling yarn?
LDPE is the abbreviation of Low-Density Polyethylene. The cool yarn is a yarn made of LDPE fiber, which has moisture absorption and sweat-wicking properties and can quickly absorb moisture and sweat from the surface of the skin, and transmit and diffuse it to the clothing. Surface, even in humid environments, can keep the skin dry and pleasant mood.
LDPE yarn is a fiber made from low-density polyethylene (LDPE). Low-density polyethylene is a thermoplastic resin formed by the free-radical polymerization of ethylene monomer under high pressure. It is milky white, tasteless, odorless, non-toxic, and matte waxy particles¹. It has good flexibility, extensibility, electrical insulation, transparency, easy processing, and certain air permeability¹². LDPE yarn can be used to make ropes, mesh bags, woven bags, mattresses, and other products.
What is the difference between LDPE yarn and other fibers?
– LDPE ice cool yarns are filaments made of low-density polyethylene (LDPE), while other fibers may be made of different kinds of high polymers or natural materials, such as polyester, and cotton.
– LDPE ice yarn is a composite filament organized from a variety of infinitely long individual fibers, while other fibers may be monofilaments, composite filaments, or threads. into¹.
-LDPE FDY white Fiber and color cooling yarn has low polyethylene softness, electrical insulation, transparency, transparency, easy and certain, such as high light resistance and corrosion resistance, but moisture absorption is Poor; has good moisture absorption, breathability and breathability, and breathability, but easy to pilling and skin color, etc.
What is the difference between LDPE and HDPE yarns?
LDPE white cool yarn and HDPE color cool yarn are two polyethylene resins with different densities, and they have some differences in molecular structure, performance, and use:
– LDPE ice cool yarn is low-density polyethylene, which is polymerized under high pressure using oxygen or organic peroxide as a catalyst. It has more branched chains on its molecular chain, low crystallinity, and a density of 0.910 to 0.940 g/cm3.
– HDPE cooling yarn is high-density polyethylene, which is the product of polymerization under low pressure with Ziegler catalysts. It has fewer branched chains on its molecular chain, higher crystallinity, and a density of 0.940-0.976g/cm3.
– The advantages of LDPE cooling yarn are flexibility, extensibility, transparency, cold resistance and processability, acid, alkali, and saltwater solution resistance, and excellent electrical insulation. The disadvantages are poor mechanical strength, moisture barrier, gas barrier and solvent resistance, low heat resistance, and easy aging and discoloration.
The difference between LDPE ice yarn and HDPE ice yarn mainly lies in their raw materials, which also affect their physical and mechanical properties. In general, HDPE yarns are stronger, more abrasion-resistant, and more resistant to high temperatures than LDPE yarns, but are also harder and more brittle. LDPE yarn is softer, more transparent, and easier to process than HDPE color yarn, but it is also more deformable and aging.
What is the LDPE cooling yarn mattress?
LDPE cool-feeling mattress is a mattress with a cool feeling made of LDPE Cooling Yarn’s softness, transparency, cold resistance, and air permeability; through fine weaving technology, a unique mesh structure is formed, which can effectively improve The air circulation and heat dissipation performance, after special processing, makes it have a cool, soft and smooth touch, and can quickly dissipate heat, allowing you to enjoy a cool summer; the mattress also has antibacterial, antistatic, anti-wrinkle and other functions. It has the advantages of being waterproof, anti-mite, non-slip, easy to clean, etc., and suitable for summer use.
