Pure Living launches the first Hong Kong-developed melt-blown fabric production machine to support the Hong Kong community

Pure Living masks received ASTM Level 1 certification

HONG KONG, CHINA – Media OutReach – 8 June 2020 – Pure Living, a Hong Kong-based chemical engineering
company, has launched one-stop melt-blown fabric solutions designed by local
experts for Hong Kong. The solution offers melt-blown fabric manufacturing machines,
innovative techniques and processes for mask production. This is an important
milestone for mask manufacturing in Hong Kong, offering a steady supply of material
to meet the needs of the local market. Pure Living has successfully launched MBHK01,
its self-developed melt-blown fabric manufacturing machine, and has top notch testing
and quality control. The high quality protective masks manufactured by Pure
Living have obtained ASTM Level 1 certification. 

 

One-stop solution offers quality masks with
ASTM Level 1 certification  

 

At the beginning of the Covid-19 outbreak, Pure Living planned
to produce masks to supply customers we had been cooperating with for many
years, including hospitals, universities, and some institutions. But there was
a shortage of masks available to the general public and major manufacturers because
of a failure to ensure a stable supply of melt-blown fabrics. With the
inconsistency in the quality of melt-blown fabric supplied by traders it was be
difficult to assure the overall quality.

 

Our team hoped to purchase small-scale equipment to produce
melt-blown fabric, but we discovered the design and performance of the
melt-blown fabric equipment and accessories on the market made it difficult to
melt polypropylene and create microfibers, and the spray heads could easily become
blocked and crystallize the cloth, causing some masks to fail the ASTM Test.

 

Pure Living made use of its strong network of raw materials
suppliers from all around the world and developed our own melt-blown fabric
production to develop a one-stop solution for the production of mask materials in
Hong Kong. The masks made by Pure Living obtained ASTM Level 1 certification,
and the fabric permeability is better than most masks, which allows for easier
breathing. (please refer to the attachment on test report)

 

Horizontal machine design supports local small-
and medium-sized mask manufacturers

 

Vanessa Ho, CEO of Pure Living, said, “At the beginning of
the outbreak, many of our business partners faced great challenges with
sourcing high-quality melt-blown fabric. Therefore, we believed there was an
imminent need to develop the capability to produce high-quality melt-blown
fabric locally, to provide manufacturers with an effective solution. Our Pure
Living team is comprised of talents with expertise in scientific research and
solid industry experience. From materials sourcing to machine assembly, we have
taken a pragmatic approach by combining our experience, knowledge, and
technology. Our goal is to develop and launch a production line for
high-quality melt-blown fabric. With tireless efforts over the past four
months, Pure Living has now met a significant milestone in the research and development
of high-quality melt-blown fabric production in Hong Kong.”

 

To address the challenges faced by local small and
medium-sized mask manufacturers, we focused on the research and development of
horizontal melt-blown fabric equipment to replace the traditional vertical design.
The MBHK01 first generation melt-blown fabric production machine can be set up
in spaces with lower ceilings and, at the same time, it requires less space. Small
and medium-sized mask manufacturers can now become self-sufficient with the
capability to produce melt-blown fabric with lower set up costs and less
space.  They will be able to supply Hong
Kong with quality and cost-effective masks for the long-term.  

 

Mastering melt-blown technology to control product quality

 

This project required a high level of industry expertise
and technical sophistication in different disciplines at every step, including
project planning, design, development of production line, selection of
materials, and production. Finally, quality assurance checks and controls are
the most important elements of the process.  

 

Pure Living invited Professor Hu Jinlian of the Department
of Biomedical Engineering of the City University of Hong Kong to take part in
the project as a technical consultant. Professor Hu gave recommendations on the
parameters of formulation for production and production line enhancement. She
also led the testing and analysis of product quality, which is essential in
enhancing the production process and assuring the product quality meets
international standards.  

 

The production process of Pure Living high-quality
melt-blown fabric is rigorous and precise. 
The raw polypropylene is melted in the extruder at high temperatures and
filtered by multi-layer fine metal mesh to isolate impurities. Following that,
the polypropylene is ejected from a nozzle through a series of fine holes at
high pressure to produce a filiform shape. These filaments are collected and
cooled by a transportation belt, and the original filaments soon become a dense
melt-blown fabric. Finally, the melt-blown fabric is double-electrostatically
treated to enhance filtering and permeability. Then, it is cut and collected
into rolls of the required size. 

 

Committed to scientific research for Hong Kong

 

Vanessa Ho added, “Although we have seen an increase in
overall supply of melt-blown fabric in the market and adjustments in pricing,
we noticed that the public is increasingly attentive to the quality of the
materials used for mask production. The market demand for high-quality
melt-blown fabric will continue unabated. 
Pure Living developed a one-stop solution for melt-blown fabric for masks,
through our own research and development capabilities.

 

This provides local mask manufacturers with suitable equipment,
high-quality materials and the process to finetune their production lines.  Local manufacturers will be able to manage the
quality control to enhance filterability of masks.  The lower production costs allow local mask manufacturers
to adopt a more long-term and sustainable business approach.”    

 

Moreover, the protective masks produced by Pure Living have
obtained ASTM Level 1 certification.  Currently,
Pure Living is a supplier of masks to major local organizations such as the
University of Hong Kong.  The company
also exports the masks to overseas markets.   

 

“As a Hong Kong-based science and technology enterprise, we
are committed and passionate about contributing to Hong Kong with our strengths
in the chemical industry. 

We are pleased that our R & D results will enable local
mask manufacturers to produce high-quality melt-blown fabric going-forward.”
Vanessa Ho added.
