Functional Finishing

   
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
pH : 7-8
Ionicity : Cationic
Main component : Specially modified nanoemulsion
Solubility : Easily dissolves in water in any ratio
 

Features

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

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

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.

Pollen-absorbing finishing agent
QUEENSETER PLC Asol&Bsol
Queenseter PLC Asol. and Bsol. are finishing auxiliaries potently capable of absorbing (catching) pollen and preventing its dispersion through formation of a special soft resin film on fiber.
 
PLC Asol
Appearance : Transparent pale yellow liquid
pH
: Approx. 5.0 (stock solution)
Ionicity : Nonionic
Main component : Aqueous polyurethane resin
Solubility  : Easily dissolves in water in any ratio
 
PLC Bsol
Appearance : White emulsion
pH : Approx. 4.0 (stock solution)
Ionicity : Cationic
Main component : Aqueous polyurethane resin
Solubility  : Easily dissolves in water in any ratio
 

Features

Features
 
(1) Effectively absorbs (catches) pollen such as that of the Japanese cedar and the Japanese cypress,
     preventing its dispersal into the air. Pollen so attached can be removed easily with light washing.
     The properties for pollen absorption and removal in washing have good durability with practically no
     deterioration even after repeated washing.
(2) Produces a soft hand in treated fabric. While the structure of the special resin film results in strong
     adhesiveness or pollen, the fabric surface remains smooth, soft and free from tackiness.     
(3) Applicable for all types of fibers including cotton, rayon, polyester and acryl.
(4) Causes no yellowing due to curing or otherwise color alteration after treatment. 
 

Method of use

Method of use
 

The amounts used vary according to the kind of substrate and its surface, the following are considered to be standard for general usage.

 

Queenseter PLC A sol. 1.5-2.5% sol. Padding→drying
Queenseter PLC B sol. 1.5-2.5% sol.
  
●Although not especially required after treatment, curing will improve fastness to repeated washing.
●Preliminary testing of possible influences on the pollen absorption (catching) effects in cases of simultaneous use with other auxiliaries.
●Fastness verification is necessary.
