Characteristics of LIPIDURE^® for fiber processing

Characteristics of LIPIDURE® for fiber processing

LIPIDURE^®-MF, CF and AF

Make fibers resemble inner tissues by

Forming water-retaining gel membrane on fiber surface,
Adding a structure resembling the intercellular lipid lamella structure of horny layers, and
Increasing water and moisture absorbency.

LIPIDURE^®-NS

Makes fibers resemble the corneous tissue by

Forming water-repelling membrane on fiber surface,
Forming a structure resembling the intercellular lipid lamella structure of horny layers, and
Increasing flexibility and skin-protective power.

LIPIDURE^®-MF, CF and AF

Basic functions

Durability to laundering of LIPIDURE^®-MF3-processed fabric

Fabric tested	Polyester cotton (65%, 35%) knit fabric
Processing	Processing agent: LIPIDURE^®-MF3 Concentration: 5% Acetic acid: 0.05%
Procedure	1. Immerse the fabric in LIPIDURE^®-MF3 2. Wring the fabric (wringing percentage: 80%) 3. Dry the fabric (100°C × 2 minutes) 4. Cure the specimen (150°C × 3 minutes)
Surface analysis	X-ray photoelectric spectroscopy Density of MPC on the surface is measured. (Number of P atoms / number of C atoms)

C1s spectrum	P2p spectrum
Biding Energy (eV)	Binding Energy (eV)

P/C value (density of MPC component on surface)
Immediately after processing: 1.79 × 10^-2
After 30 times of laundering: 1.59 × 10^-2

-->

Over 80% of MPC components were retained even after 30 times of laundering.

LIPIDURE^®-MF3 forms durable coat that resembles biological membrane.

Japanese criteria	Reaction	Score
-	No reaction	0
±	Slightly red	0.5
+	Clearly red	1.0
++	Red and swollen	2.0
+++	Red, swollen and slightly blistering	3.0
++++	Blistering	4.0

Irritation reduction test
Skin irritation index = total score / number of subjects × 100

LIPIDURE^® blocks irritants and protects the skin.

LIPIDURE^®-NS

	Adsorb on fiber		Rearrange the structure

The lamella structure of LIPIDURE^®:

Protects the skin because its corneous-tissue-like structure retains moisture and blocks irritants.
Gives soft and comfortable texture because the skin-like structure is flexible and temperature responding, and
Confines active components of both hydrophilic and hydrophobic properties between the lamellas.

pH at processing

MF and NS show better adsorption and durability when processed under acidic conditions.
CF can be processed in a wide range of pH and is suited for immersion because it adsorbs well.
AF may settle at pH lower than 5.

Drying temperature

250°C, about 2 minutes
The durability of MF, CF and AF is improved by curing at high temperatures.

	Nano-particle fiber processing agent “^® (lotion for lingerie)”
	“^®” is a Registered Trademark of NOF CORPORATION in Japan.

“^®
(lotion for lingerie)”
Sample: 100 mL

Just by spraying, “^®” (lotion for lingerie)” gives garments a soft and bio-affinitive texture.

Phospholipid polymers “LIPIDURE^®” are widely used in products that need to be especially affinitive to human body, such as cosmetics, medical devices, and contact lenses.

Our skin

Our skin is exposed to diverse stimuli every day.	The corneous tissue is the outermost layer of the skin.	It has a lamella structure of cells and protects the skin from the stimuli.	The cells are made of phospholipids.

“^® (lotion for lingerie)”

Phospholipid-like structures are encased in polymers.	The polymers in form of nano-particles are dispersed in water.	The nano-particles adsorbs on fiber surface and rearrange their structure at drying.	A lamella structure is formed and enhances the barrier functions of the skin.
