Technidyne Nominated for Award

For the second year in a row, Technidyne Corporation has been nominated for a Family Business Award.

Technidyne has been nominated for a Family Business Award for Family Businesses in operation over 35 years through the Goering Center for Family & Private Business at the University of Cincinnati.  The Goering Center facilitates learning and progress of family businesses by hosting educational programs, expert presenters, best practices and research.  Topics include: business boards, leadership, succession planning and strategic planning to name a few.  All of these are geared toward Family and Privately-owned businesses.  Here is a calendar of events for the upcoming months.

Winners of this years awards will be recognized at the 15th Annual Tri-State Family & Private Business Awards, August 26, 2014 at the Cincinnati Music Hall.

In 2013, Technidyne Corporation was the recipient of the GLI Inc.credible Award for Global/International Small Business.

Some History from Cascades

Long before "sustainable development" became a fashionable concept, the Lemaire family had earned its livelihood from recycling at Drummond Pulp & Fibre, the household and industrial waste recovery company it had founded in 1957. What most consumers saw as nothing more than a landfill was a hidden treasure to Antonio Lemaire. He tested the first recycled paper recipes himself...using his wife Bernadette's blender!

Improving Sheet Forming

Techpap On-Line 2D Formation
IBS uses the Techpap On-Line 2D to set up their iTable.  The iTable has many adjustment points and can take input from the refiners, furnish blend and headbox.  By using the 2D, IBS can very accurately adjust the furnish, refining, headbox and table to meet the formation requirements to achieve a particular production.  In the past IBS needed to make a complete paper roll to test before changes could be made.  This could take weeks to get a table set up.  With the 2D this setup time has been shortened to days.

As seen with these technologies, the higher pulsation frequency (150-600 Hz), the higher the microturbulence produced resulting in the highest shear levels possible during the forming process. This results in increased fiber mobility and the best possible formation.

This will affect the following paper quality and machine properties:
  • Drainage
  • Formation
  • Basis weight and moisture profiles
  • Fiber orientation
Benefits include:
  • Increased drainage capacity
  • Increased refining capacity
  • Improved formation
  • Improved smoothness
  • Improved TSO angle profiles
  • Improved tensile ratios
  • Increased sheet strength
  • Reduced basis weight
  • Reduced chemical cost
  • Increased machine speed

TAPPI Process and Product Quality Scholarships for 2014

Two scholarships were awarded by the TAPPI Process and Product Quality Division for 2014 at the recent PaperCon in Nashville, TN.  There were 16 students that applied for the scholarships.  The two winners were:

          Tyler Shimulunas, University of Wisonsin - Stevens Point
          Charlotte Seeley, Michigan State University

Each college student receives $1,000 toward their continuing education in the field of Pulp and Paper. There were 16 scholarships awarded at PaperCon by various divisions of TAPPI.

Todd Popson, CEO & President of Technidyne Corporation, is the most recent Past-Chairman of the TAPPI Process and Product Quality Division. He is also a member of the Scholarship Committee and PaperCon Steering Committee.

Setting Tolerances

Customers ask all the time, "What is the best way to determine a production tolerances?" I'll use color as an example to help answer this question.

Generally speaking in the Paper Industry we are normally dealing with near-white colors. In that case, we often use the rule of thumb that +/- 0.3 in L*, a* or b* is visually perceptible. However, when we start to look at more saturated colors the question becomes much more difficult.

L*a*b* color tolerance
Color tolerance vs. Visual acceptability
If we set a tolerance based on L* a* b*, the color space we are looking at is cubical. However, when we plot actual visual acceptability it is more ellipsoidal-shaped.  See at the right, the black shading represents numerical acceptance, but visually unacceptability.

Obviously, there is a difference here. If we look at the ΔEcmc tolerancing which is based on ellipsoidal tolerances, this does a much better job of matching visual and numerical acceptability.  Looking at a particular cross-section of the a* b* space (below), we can see that the visually acceptable ellipses vary in size depending on the position in color space. The ellipses in the orange area of color space are longer and narrower than the broad and rounder in the green area. The shape of the ellipses are larger as the color increases in chroma (away from a*=0, b*=0).
This means that visually acceptable differences in L*, a* and b* differ depending where we are in color space.  A Δa*=0.5 would be noticeable on a near-white, but Δa*=5.0 on a red may not be noticeable.

The best advice is to give your customer a series of samples that vary from the target by different amounts. Let them visually analyze the samples and tell you which ones they would accept and which ones they would reject.  You can measure all of the samples and help define tolerances based on their feedback.  It may also be helpful to keep an archive of samples (over time) that they have rejected. This will help you hone the tolerances based on complaints, returns or rejects.

This same concept can be used for many other measurable quantities as well. Brightness, Gloss, Opacity, Smoothness, Softness, Tensile, Formation, Burst and many more parameters can have tolerances set around them. Giving your customer a say in the matter and then keeping a record of their historical actions can build a strong quality program.

Tissue Softness

There were a lot of good questions and conversation at PaperCon last week about Tissue Softness.  Here is some explanation of some of the results from the Emtec TSA.

The output of the Emtec TSA goes far beyond just giving a single softness number with excellent correlation to hand feel panel tests. It provides all the data needed to explain the softness number so a determination can be made as to why one product is softer than another.  The feeling of softness one gets from a sample is a combination of three main parameters: softness, structure and stiffness.  Here is an explanation of some of the outputs generated by the TSA:

TS7 - Softness Parameter
The TS7 softness peak is the frequency peak that occurs around 6.5 kHz on the noise spectrum graph.  This peak represents the pure softness and is influenced by the fiber furnish, the degree of refining, the chemicals and other factors concerning the real softness of the sample.  Generally, softer samples produce a lower TS7 peak.

TS750 - Structure Parameter
The TS750 structure peak is the peak at a frequency that falls around 200 - 1,000 Hz. However, this frequency is not fixed like the TS7; it can vary in this range.  This peak represents the structure of the sample which includes such things as creping and embossing.  Generally, samples with lower structure strength will produce a lower TS750 peak.  The creping and embossing process is done to realize a specific structure as it relates to hand feel.  Creping and embossing will tend to make this peak higher.

D (mm/N) - Stiffness Parameter
This is the deformation of the sample under a defined load and refers to its stiffness.

HF - Hand Feel
This HF number is the calculated figure which corresponds and correlates with the Hand Panel Test.  The higher this number is the softer the test sample is and the better it is with respect to hand feel.  Hand Feel is when someone touches the sample by hand and ranks it.  This is a combination of the other parameters described above: TS7, TS750 and D.
