Simplicity vs, Complexity

“For every complex problem, there is a solution that is clear, simple, and wrong.” – H. L. Mencken

The operation of a Micrex®/Microcreper™ is complex. I wish it were not that way. Success only came when we embraced the difficulty and committed to being technologists rather than machinery manufactures.

The way Micrex deals with the complexity is through our extensive trial program. During trials we have customers who quickly form their own theories on how the technology works. Good minds do that, but unfortunately the desire to immediately understand something blinds one to the complexity.

I like to give the example of musical instruments. To me the piano looks hopelessly complex. Many keys and combinations of keys. The trumpet has only three keys and usually leads the band. As a child I chose to play the trumpet. A big mistake for me and I am sure little joy for my parents. The trumpet requires weeks of practice before managing the most basic tune. Had I done some research and developed a better understanding of the issues I would have chosen the piano and been making music from day one rather than a lousy horn player.

This is in complete conflict to Occam’s razor where the simplest theory is given priority.

Rethinking Textile Replacements

The disposable paper dress, in 1966 a revelation and new development, has proven to be a failure. The nonwoven substrates available at that time made unappealing, uncomfortable products.

Since then, the nonwovens industry has developed, and the time is right for new, improved products to replace textiles, going beyond fashion and the paper dress, such as hospital bed sheets, tablecloths and window treatments.

This is where Micrex technology comes in:

Paper dress

Happy?

You can use Micrex’s technology to transform nonwovens from 2D into 3D materials. You can also add properties such as softness and stretch, more closely matching the desired qualities of textiles than ever before:

Add softness: get rid of harshness in your sheet material.

Turn 2D into 3D: add three dimensional effects to your nonwovens. At Micrex, we have been adding these 3D effects to several grades of nonwovens for years.

Add extensibility (comfort stretch): at the same time as adding a decorative effect – providing you with a huge advantage over other technologies. The result: a textile replacement with desirable textile properties.

Best Practices for Roll Goods Trials

trials

The product development process starts with a trial, and at Micrex, every new product we develop also started this way. We’d like to share what we’ve learned about the trial process to help ensure that your next trial a success. (Updated May 2, 2022)

Roll Goods Trials – Best Practices

Operating in The Pandemic: What we have learned so far.

In January 2020 I read a couple of books about the 1918 flu.  Within a few weeks it became clear that for the time being these books remained the state of the art in virus mitigations and public health.

In March as the state shut down business, we were notified by several customers that we were considered essential and expected to keep operating.  This raised a lot of questions – particularly how do we keep our employees safe?

Guidance from the government was initially vague, but like any safety challenge there is a systematic way approach the issue.

  • Relying on the 1918 teachings we immediately supplied masks, and instituted social distancing.
  • Our employees were used to working on medical products, so we had the necessary PPE and hygiene supplies along with the training in how to use them.
  • Our two shifts modified there schedule so there was no overlap.  Extra end-of-shift cleaning protocols were implemented with the between shift being done by management as a further check.
  • To reduce the office density, one half of the office staff went on a work-from home schedule.  As we already had the IT tools in place, this was basically seamless.
  • To eliminate ambiguity, we wrote policies to dictate the response were an employee to get Covid.
  • To minimize exposure a staffing freeze was implemented, and no visitors were allowed in the plant.

Two further measures were taken which may have been critical:

  1. Three stand-alone filtration devices were acquired and located in areas where distancing was more difficult.
  2. We ran an exhaust fan all winter.  Combined with several air inlets this allowed us to run “negative pressure” in the entire plant.  Despite the impact on our heating bill, we feel this was one of the most important mitigations.

While the pandemic is not over, these measures along with everyone’s compliance has kept Covid out of Micrex.

Why Micrex Will Not Sell Lab Machines

When Micrex technology was in its infancy in the 1960’s and 70’s, the company’s strategy was to outfit leading firms in the nonwovens, paper and packaged goods industries with small scale R&D equipment to foster product development. This strategy was pursued, and about ten lab-scale Micrex®/Microcrepers™ were sold.

Following the machine sales, Micrex waited for these R&D machines to start producing new commercial products. Our management was patient and continued to sell R&D lines.

Armed with the perspective of over 50 years of pursuing this R&D strategy, we note that none of the R&D machines in the hands of our customers produced a successful commercial product. The absoluteness of this outcome was stunning. Why were these machines not succeeding? In fact, it was even worse. Companies with R&D equipment were not running trials at Micrex either. It was as though possession of R&D equipment prevented companies from using Micrex technology.

Learnings

In the last twenty years we have developed insight into what happens with the equipment:

    1. The key to why the strategy failed is understanding that Microcreping a new substrate is difficult. At Micrex we have nine different configurations of equipment to apply. At best, our customer might have two or three of these configurations. This means the customer began with only 1/3 the capability we have available at Micrex.
    2. When we train a customer’s operator for an R&D line, realistically that operator might only retain 80% of what they are taught. Back at their company, they would likely have duties other than Microcreping. Over time some of our training is forgotten. Eventually they are retired/fired/transferred/promoted and must train their successor. This successor likely captures 80% of what they are then taught. Simply put, over time the knowledge and best practices taught at Micrex are lost.In contrast, at Micrex all we do is Microcrepe. Our operators run a wide range of substrates and participate in our customer trials. Their skills become better and better over time.
    3. No one in business likes to admit what they don’t know; therefore, rather than seek help from Micrex, a company’s R&D machine often becomes a type of test stand that proves the technology does not work. Because of the limited configurations and the loss of machine knowledge — they only have 1/10th the chance of success when compared to Micrex.

While these learnings seem very negative, the reality is that literally hundreds of highly successful products have been produced by Micrex/Microcrepers around the world. The operative question for Micrex was then: if the R&D machines did not provide the path to aid new product development, what would?

Our solution: screening trials at Micrex. That is how our Free Screening Trial Program was born. The R&D trials are carried out at Micrex. Our technical team brings years of experience and a breadth of equipment. While we figure that a “free trial” actually costs Micrex about $2,000, it provides a seamless and speedy way to get a reading on whether Micrex technology might be applicable for a customer product. Further, performing these trials improves our skillset on the machine, and informs us on what our customers want.

Screening Trials arrive at Micrex from all over the world daily. Usually we can give feedback to the customer within a few days.

To save time, money and increase your likelihood of success, we recommend that you forget about the R&D machine, and try a Screening Trial.
