So-called "vanity sizing
" is said to be creeping into stores with retailers cutting clothes larger but keeping the same size.
The new starch substantially increases the sizing
efficiency of ASA.
They also provide proper prediction domains for sizing
. The simplified models provide some insight into the difference between esterified sizes and fortified sizes for the relationships between paper sizing
and the factors of pH, temperature, water hardness, and fortification.
What is the effect on alkyl ketene dimer (AKD) sizing
when aspen high-yield pulp is substituted for hardwood kraft pulp?
compounds have now been synthesized to overcome these problems.
As expected, sizing
increased markedly with dosage over the range of dosage studied.
S-cutter press-side sprue/runner return granulator produces uniform particle size with minimal fines at low rotational speed of 30 rpm without a sizing
More effective internal sizing
, including ASA's on-machine curing capability, means less surface sizing
, which improves printability.
In this work, the researchers studied the effects of impulse drying on AKD retention and on the efficiency of sizing
. Impulse-pressed handsheets beaten to 25[degrees]SR or 40[degrees]SR were prepared.
The two most important parameters to consider in sizing
a dryer are air flow (cubic ft/min or cfm) and process-air temperature.
As furnishes become more contaminated, the higher sizing
efficiency of ASA is also preferential over using increasingly more AKD to achieve the same result.
The correct granulator selection matches the rotor and knife design, knife clearances, rotor speed, and screen sizing
to the infeed material's properties and physical form.
