Protex Fiber is a modacrylic fiber with improved flame and heat resistance while maintaining its inherent supple texture.

Protex® (Protex®)

 

PROTEX® is a modacrylic fiber with improved flame and heat resistance while maintaining its inherent supple texture.

 

 

Excellent flame retardancy (material flame retardant and self-extinguishing)

PROTEX is a material flame-retardant fiber in which the fiber resin itself is flame-retardant, and has self-extinguishing properties that stop combustion as soon as it leaves the source of fire. Unlike the flame retardant performance of post-processing, its flame retardant properties do not diminish or fade with washing.

 

Hard to melt (carbonized type)

When Protex burns, it forms a carbonized film that prevents the spread of fire and stops burning in a short period of time once the fire source is gone. Unlike polyester and other molten fibers, Protex does not melt and adhere to the skin when it burns.

 

Soft, light and comfortable

Protex is lightweight, warm, and resilient, and its unique fiber shape gives it a soft and supple texture.

What is WHOLEGARMENT...

Usually, knitwear is made by sewing together parts such as the body and sleeves.
In contrast, a whole garment of WHOLEGARMENT® knitwear is knitted three-dimensionally, directly from the knitting machine.

↓arrow (mark or symbol)

This eliminates the need for processes such as cutting and sewing, saving time.
It enables the realization of completely new knit products, such as three-dimensional molding that requires advanced sewing skills and complex items that are impossible to sew.
*Some sewing may be required depending on the product.

 

SEAMLESS

Clean silhouette with no gore due to seams or joints. Soft, lightweight, comfortable fit and feel

■Limiting oxygen index (LOI value)
Limiting Oxygen Index (LOI value) is an abbreviation for Limiting Oxygen Index.
It is one of the indicators of "flammability" or "combustibility" by showing the minimum oxygen concentration required to keep burning.
The higher the value, the more oxygen is required, which means it is less flammable in air.
Since the oxygen ratio in the atmosphere is about 20 to 21%, it is generally said to be flammable if the oxygen index is 22 or less, and flame retardant if the oxygen index is 27 or more.
