PAPERMAKING CHEMICALS
Creping Adhesives / Creaping Release Agents / Softeners
Creping Adhesives / Creaping Release Agents
These agents are commonly used in the process of imparting fine and uniform ridges in household paper products such as tissue / toilet paper.
This process is called creping and it is done as the tissue sheet is pulled from the dryer using a doctor blade.
CREPING ADHESIVE CA Series / CREPING RELEASE AGENT CR Series
- These agents reduce abrasion of doctor blade due to the formation of a uniform polymer film on Yankee dryer (in drying part).
- They improve adhesion of the wet sheet to Yankee dryer, and control the release of the sheet from the dryer at the doctor blade.
| Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
|---|---|---|---|---|---|---|
| CA6003 | Polyamide epichlorohydrin | Cation | 10 | 20〜80 | 8.0〜10.0 | Non-reaction-type adhesive. Form excellent adhesion and water resistance coating film.. Suitable for crepe control of medium- and low-speed machines. |
| CA6006 | Polyamide epichlorohydrin | Cation | 15 | 15〜50 | 3.0〜5.0 | Reaction-type adhesive. Form excellent adhesion and water resistance coating film.. Suitable for crepe control of high-speed machines. |
| CR6104 | Modified hydrocarbon oil | Nonion | 100 (Effective portion) | 150> | － | Release agent for external addition. Excellent releasing effect. |
| CR6157 | Modified hydrocarbon oil | Cation | 100 (Effective portion) | 150> | － | Release agent for external and internal addition. Higher releasing effect than CR6104. |
Example of using CA / CR Series
CA / CR form a uniform coating film in the width direction that has excellent adhesion.
They improves performance of the creping process.
They improves hand feel of the paper by giving fine crepe.
Softeners
Their application improves softness and provides a pleasant, comfortable feel to the paper.
These agents are commonly used in household paper products such as tissue / toilet paper.
SOFTENER FS/GT Series
- They improve the softness of paper.
- They help smooth the surface of paper that gives the paper a more pleasant and comfortable feel.
| Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
|---|---|---|---|---|---|---|
| FS8006 | Fatty acid derivatives | Cation | 90 | 500> | － | Improves the softness, smoothness, and bulk of paper sheet. |
| GT8022 | Fatty acid derivatives | Amphoteric | 40 | 300> | 8.0〜10.0 | Improves the smoothness and bulk of paper sheet that is superior that to FS8006. |
Example of using Softeners
Softners enhance the softness, smoothness, and feel of hand meat on paper by form gaps between fibers.
