Powder stain prevention agent

Pollen-release finishing agent

QUEENSETER POL
Hay fever, in which pollen as typified by that of the Japanese cedar and the Japanese cypress works as an allergen, is a common modern ailment which causes unpleasant symptoms such as sneezing and a stuffy nose. Cedar pollen can be dispersed to a concentration of 4000~10000 grains/cm2 in a season when the count is high. As matters stand with the size of these fine grains being 30~40µm, prevention of pollen adhesion and its removal require very complex technology.
Queenseter POL is a pollen-release finishing agent, which makes pollen adhesion to fiber difficult and easy removal once it does adhere, by coating fibers with a soft but strong resin film based on a unique atomizing technology.

Appearance : Colorless translucent liquid
Ionicity : Cationic
Main constituent : Specially modified nanoemulsion
pH : 7-8
Solubility : Easily dissolves in water in any ratio

Features

(1) Prevents adhesion and aids removal of pollen as typified by that of Japanese cedar and Japanese cypress. Effects will not deteriorate even after repeated washing.
(2)Does not cause coarsening of hand or any hindrance to water absorbency in treated fabric.
(3)Causes no yellowing due to heat, no discoloration after treatment and does not adversely affect colorfastness.
(4)No heat treatment such as curing or setting required as it forms a strong resin film on fiber simply through the evaporation of the water content.
(5)Applicable for any type of fiber.
(6)Queenseter POL has also effective against soiling with sand, dirt, dust and the metabolic waste (e.g. remains, faeces) of mites.

Method of use

Aside from continuous padding and dipping methods, a spray method can also be used. The amounts vary depending on the type and surface of substrate, however, the use of the following is standard:

Padding:5~10% sol. padding→drying
Dipping:5~10% owf. dipping(room temp x 10min.  liquor ratio 1:10)→squeezing→drying
● 
While heat treatment is unnecessary after treatment with Queenseter POL, it does not produce any adverse effects.
Simultaneous use is possible with other auxiliaries such as antistatic or softening agents. Preliminary, thorough testing on compatibility is necessary as the effect of pollen release may deteriorate considerably depending on the kind of auxiliary.

Test method

● 
Prevention of pollen adhesion
Specimens were placed in a bag containing 0.1g of lycopodium powder (spores of club moss), shaken 50 times, removed from the bag and lightly shaken before the quantity of attached pollen was determined.

Substrate:Polyester
● 
Prevention of dirt adhesion
Specimens were placed in a bag containing 1g of a mixture of akadama soil, standard soil and carbon black, shaken 50 times, removed from the bag, and lightly shaken before the level of soiling was evaluated with the naked eye.
