Heat_humidity Comfortable Regulating Polyester Fiber

The innovatively designed polyester fiber with differential deformation

in response to heat and humidity endows the fabric with the ability

to actively regulate the human microenvironment by adjusting its

air permeability rate. This unique feature allows for rapid moisture

permeation and sweat evaporation, keeping the skin surface dry and

ensuring continuous comfort for the wearer. It creates an application

scenario where “the more you exercise and the more you sweat, the

more breathable it becomes”

Preparative technique

After esterification of polymeric raw materials, modified monomers are added, and the process proceeds through steps such as pre-polycondensation and final polycondensation to prepare low heat-humidity stimulating polyester chips and high heat-humidity stimulating polyester chips, respectively. Subsequently, these two types of polyester chips are used to produce the fiber through a two-component melt-composite spinning process.

The downstream application guidance
Weaving: It is used to produce knitted and woven fabrics. The degree to which product advantages are manifested is closely related to the structural design of the fabric. Therefore,knitted fabric can exhibit the functionality of the product to a greater extent.
Dyeing: It is recommended to adopt the high-temperature and high-pressure dyeing method with disperse dyes. For light and medium shades, E-type disperse dyes are recommended,while for dark shades, SE-type dispersed dyes are preferred.

Q:How does heat-humidity comfortable regulating polyester fiber achieve active adjustment of the human microenvironment through structural design and molecular association?

A: The research and development of heat-humidity comfortable regulating polyester fiber is based on ecological simulation. The fiber is crafted after a thorough analysis of the structural principles of heat-humidity drivers. The fiber is composed of a composite of two components: low heat-humidity stimulating polyester and high

heat-humidity stimulating polyester, and adopts a form of symmetrical section and asymmetrical internal structure to integrate high polymer molecular design with fiber performance expression. In conditions with high temperature and humidity,deformation occurs between the two components of a single fiber, causing the fibers to become closer to each other. Subsequently, the pores of the fabric open up,facilitate the release of heat and moisture, and accelerate the evaporation of sweat.

In conditions with low temperature and humidity, the fibers become fluffier and the porosity of the fabric decreases, achieving insulation and moisture retention.
