Infrared-reflective hollow polyester fiber

Functional update and technological deconstruction. Fiber technology has stepped up the stairs of the times in the development and iteration, coexists with ecology, functions and emotion, and continuously extends more potential. With our increasing demands for health management, the functional protection of the body has obtained more attention. Cool feeling,bacteriostasis, far infrared, heat locking and cooling, anti-ultraviolet, anti-static electricity and air purification have become our great demands for psychological security.Multi-functional composite fiber provides the best care in healthcare, safety protection and heat-humidity adaptation, helping us travel freely with no fear of environmental changes and experience the fashion of life technology.

FUNCTIONAL DECONSTRUCTION

MULTIFUNCTIONAL COMPOSITE FIBER

Multi-functional composite fiber, guarding health with leading technology.Miraculous rare earth functional particles create lightweight, heat insulation and cooling,infrared reflection functions, creating thermal comfort for the human body with surrounding micro-environment.In-situ polymerization modification technology deeply embeds anti-bacteria, flame retardant, anti-static, anti-ultraviolet, formaldehyde-removal and other multiple functions into molecular chain segments, making one fiber with multi-purpose. It pioneers in dual anti-bacteria effect of plant and animal active substances, and upgrades the contents of cellulose fiber protein and 14 kinds of amino acids,escorting scientific health care.

Infrared-reflective hollow polyester fiber

Recommendation Reasons

The fiber has mechanical properties, lightweight, heat insulation and

cooling, infrared reflection functions. It creates thermal comfort for the human body with surrounding local micro-environment.

Processing Technology

Rare earth functional powders and polymer powders are blended, and rare earth composite functional master batches are prepared by compounding master batch additives of different ratios. Then the composite master batches are blended with polyester slices to prepare infrared-reflective hollow polyester fibers by melt spinning technology.

Q: Do you know the functional mechanism of infrared-reflective hollow

polyester fibers?

A: Today, there is a growing demand for multi-functional yarns, fibers and fabrics. Textiles provide a protective barrier for the body and play a key role in heat exchange between people and the environment. Rare earth nano particles have two optical properties: firstly, they have good reflectivity for visible near-infrared light with the wavelength of 400~2,500nm, reducing the absorption of solar radiant energy; secondly, they have good infrared emission ability in the thermal infrared wavelength band of 8~14um,facilitating the heat exchange between the human body and the cosmic environment. Based on the above characteristics of rare earth nano particles the development of fibers with good heat insulation and infrared emission properties will further open up the market for functional textiles.
