  • Product Detail

Aerogels are a class of synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas, without significant collapse of the gel structure, which result in a solid with extremely low density and extremely low thermal conductivity.

Runteks is promoting and selling aerogel yarn.
Aerogels have a porous structure and contain a high percentage of air (>95%), this results in its extremely low density (the lowest aerogel can be 0.16 mg/cm3).

Air itself is a poor thermal conductor, but it can still transfer heat by convection. However, in aerogel, the narrow space in the nanostructure hinders air molecules from moving freely and effectively, and hence prevents convection of the air trapped inside , which enables aerogel to be an even better thermal insulator than air, its thermal conductivity is as low as 0.013W/m∙K.

The applications of aerogel yarn are very extensive, in addition to outdoor clothing and thermal underwear, they can also be used in bulletproof vests, tents, sleeping bags, knee pads, yoga clothes, and other fields.

At present, the use of aerogel yarn in the textile and clothing market is mainly concentrated on winter cold-proof and thermal insulation products. Traditionally, this clothing sub-market is mostly occupied by cotton, down, wool, cashmere, and acrylic products.


As a result, aerogel yarn may also be a direction for the development of thermal insulation fibers in the future.

Hollow Bio Based And Thermal Storage Hollow Fiber
Runteks Group's new product: Hollow Sorona series Hollow Sorona With Heat Blocking And Cooling Effect  The hollow Sorona, with its unique spiral structure and innovative 4C hollow cross-section spinning technology, significantly optimizes the thermal management performance of the fabric, providing heat and cooling insulation. This design effectively slows down the rate of thermal energy rise in the fabric, allowing wearers to enjoy a long-lasting cool experience even in high temperature environments.  How effective is the cooling sensation of Sorona? By efficiently blocking the transfer of solar radiation heat to the body surface, the hollow Sorona significantly reduces the impact of external temperature on body sensation, ensuring comfort and heat insulation during wear. Experimental data shows that compared with equivalent fabrics, hollow Sorona fiber fabrics perform well in slowing down the rate of thermal energy rise, with a heat shielding rate of over 55%, demonstrating their leading position and excellent performance in the textile industry. Advantage:QUICK-DRYING,HIGH REBOUND,ICY COLD,BIOBASED Thermal Storage Hollow Sorona After high-temperature wet processing, the thermal storage hollow Sorona forms a curled structure due to significant shrinkage differences, significantly enhancing its elasticity.  In terms of insulation technology, the principle of simulating the vacuum layer of a thermos can effectively block the heat transfer from the human body to the outside world.  At the same time, by reducing the gaps between fabrics, suppressing air flow, and reducing heat convection losses. Special far-infrared thermal storage materials can absorb and radiate far-infrared radiation with wavelengths similar to human radiation, forming a resonance effect, absorbing human energy and feedback, increasing skin temperature, achieving efficient thermal storage and warmth retention, and bringing a dual enjoyment of technology and comfort to fabrics. Advantage:HEAT STORAGE,WARM What are the main specification available ? Specification:FDY SD and FD in 45D, 50D, 65D, 75D, 85D, 130D

Polyester flame retardant FR monofilament yarn 20D Metal Cops
Flame-retardant monofilaments, also known as flame-retardant monofilaments, refer to monofilaments that smolder only in the flame, do not generate flame themselves, and extinguish themselves when leaving the flame, which are widely used in clothing, home, decoration, non-woven fabrics and fillers. Traditional flame-retardant monofilaments (for example, pet flame-retardant monofilaments) are generally made by adding flame retardant into raw materials, which can be permanently flame-retardant, but the amount of flame retardant added is high, resulting in higher production costs.
