Graphene Heat-Storage Staple Fiber
Advanced Graphene Technology for Thermal Comfort
Developed with graphene-modified PET technology, our heat-storage staple fiber is designed for warmth-focused textile applications.
With customizable solid or hollow profiles and flexible blending options, it supports the production of thermal underwear, knitted fabrics and performance textiles.
Product Overview
This graphene heat-storage staple fiber is manufactured via melt compound spinning of PET and graphene modified masterbatch. The few-layer graphene microplates feature high aspect ratio and achieve homogeneous dispersion in the polyester melt. Natural grey are standard colors. Round cross-section is the default structure, and hollow profiles can be supplied upon request. The fiber is suitable for pure spinning and can be blended with cotton, modal and spandex for thermal underwear and similar applications. The blending ratio can be adjusted according to fabric warmth requirements and hand feel. The mechanical properties of the fiber can be optimized for downstream spinning processes to fit various knitted and woven fabric applications.
Technology Principle
1. Spinning process. PET chips are blended with graphene modified masterbatch in precise proportions and made into staple fibers through melt extrusion, drawing, crimping and cutting procedures. The surface-treated graphene microplates achieve good compatibility with the PET matrix and guarantee continuous and stable spinning performance.2. Heat generation mechanism. The two-dimensional lattice structure of graphene presents high emissivity in the 8–14 μm band. The graphene microplates inside this Graphene Heating Fiber absorb infrared energy radiated by the human body and re-emit the energy back to the skin surface to form a heat retention effect. The thermal conduction network constructed by internal graphene microplates evenly distributes heat inside the fabric and reduces local cold spots. The fiber delivers a normal emissivity of no less than 0.90 and a temperature increase of over 1.5 °C after 5 minutes of infrared irradiation, in accordance with GB/T 30127.3. Additional functional properties. The unique layered structure of graphene microplates can physically destroy bacterial cell membranes and produce inhibitory effects on Escherichia coli and Staphylococcus aureus. Meanwhile, the fiber obtains greatly improved anti-static performance.
Core Advantages
High Emissivity
Normal far-infrared emissivity of 0.90 or better with an irradiation rise of at least 1.5 C gives a clear sense of warmth.
01
Three Functions In One Fiber
Heat retention, bacterial reduction, and anti-static behavior all come from a single additive.
02
Wash Durability
Functional components are embedded inside the fiber matrix, so the functional performance will not easily decay after repeated washing.
03
Soft Hand
The platelets leave fiber flexibility intact for next-skin comfort.
04
Process-Friendly
Standard polyester equipment runs the Graphene Heating Fiber with no conversion, and 20% to 40% blends already show results.
