Melt-blown cloth market chaos
Melt-blown cloth production equipment can be divided into type 60, type 800, type 1200, type 1600, etc. The overall quality of the equipment and the effect of the nozzle, It has a direct impact on the quality of meltblown cloth. According to the national standard GB2626-2006 “Self-priming Filtering Anti-Particulate Respirators for Respiratory Protective Equipment”, melt-blown cloth is divided into level 90, level 95 and level 99 according to high efficiency. Melt-blown cloth is used to make civilian protective masks. Should reach level 90 or above.
Due to the outbreak of the epidemic, the market demand for masks has exploded, and the production threshold of meltblown cloth is low. The “meltblown cloth fever” has instantly set off in China, and private meltblown cloth workshops have become more popular. It is blooming everywhere, but private workshops generally use 60-type equipment, which is difficult to meet the 90-level standard. This has also led to uneven quality of melt-blown cloth on the market. There are also many masks that have been sued and recalled because the quality of melt-blown cloth is not up to standard. Yes, causing a lot of waste of resources.
Melt-blown cloth detection method and new standard requirements
Preliminary inspection method of melt blown cloth:
1. Look at the inspection certificate, including factory address, phone number, production date, shelf life, inspection signature, roll length, width and Weight.
2. The same number of bundles packed in the same bags have inconsistent weights and gram weights, so they need to be weighed and inspected. It should not be used if the cloth roll is loose, deformed, or stained.
3. Unfold the cloth and observe with the naked eye whether the density is uniform. You can also turn on your mobile phone to light up the screen and check it against the light; cut off small pieces to check the moisture penetration.
New standard requirements:
In order to ensure that the production and sales of melt-blown cloth for masks meet the standard requirements of various types of masks, the Ministry of Industry and Information Technology will issue regulations in July 2020. Supervise the implementation of the FZ/T 64078-2019 industry standard “Melt-blown Nonwoven Fabrics” from March 1 to standardize the quality requirements of melt-blown fabrics.
The identification content that should be attached to the melt-blown cloth should include: product category, manufacturer name and address, production batch number, product specifications (mass per unit area, width, roll length and Roll weight, etc.), implementation standards, production date and shelf life, etc. Different types of melt-blown nonwovens should also indicate their special indicators and indicator values.
1. Form of logo
Identification should be in various forms such as ordinary identification, electronic identification, bar code, QR code, etc. Enterprises should take appropriate measures to prevent counterfeiting of identification.
2. Marking method and material
The logo should be spray-painted One or more marking methods should be used for printing, stamping, rolling printing, hanging signs, affixing labels and placing hang tags. The material of the logo should be hard plastic, cardboard, paper stickers, etc.
3. Position of the logo
The logo should be on each package On the initial packaging of the unit and in an appropriate location inside the packaging.
4. Management of logos
Due to inconsistencies in the logistics process If the number of signs is insufficient due to correct work, compensatory signs should be implemented. The logo should be eye-catching, strong and reliable, and the logo font should be clear, standardized and not easy to fade. The pasted logo should be smooth, without wrinkles or corners, and should be pasted neatly.
Example of logo content:
Example 1:
Product Category: Melt-blown nonwovens for masks
Manufacturer Name: XXXXX Company
Address: XXXXX
Production batch number: XXX
Product specifications: mass per unit area XXg/cm2, width XXcm, roll Length Date
Shelf life: X years or X months
Special indicators (YY 0469-2011): Bacterial filtration efficiency ≥XX% , particle filtration efficiency ≥XX%, pressure difference ≤XXPa/cm2.
Example 2:
Product Category: Melt-blown masks Nonwoven fabrics
Manufacturer name: XXXXX company
Address: XXXXX
Production batch number: XXX
Product specifications: mass per unit area XXg/cm2, width XXcm, roll length X meters, roll weight Xkg
Execution standard: FZ/T 64078—2019
Production date: XX, XX, month XX, XX year
Shelf life: X Years or ), non-oily (and/or oily) particle test medium, test flow: XXL/min. Particulate matter filtration efficiency ≥XX%, initial resistance ≤XXPa.
5. Items to be tested and the required quantity of samples
Reference Industry standard FZ/T 64078-2019 “Melt-blown non-woven fabrics Melt-blown non-woven fabrics”, recommended testing items:
1) Air permeability
2) Weight of melt-blown cloth
3) Filtration efficiency��
Quantity required for samples:
1) Width 0.5 meters and below requires 8 meters
2) A width of 0.5-1 meter requires 6 meters
3) A width of more than 1 meter requires 4 meters
Foreign markets of melt-blown fabrics
According to data, the number of new confirmed cases around the world has increased significantly. As of July On March 12, the cumulative number of confirmed cases exceeded 12.86 million. In addition to the United States, Brazil, India, the United Kingdom, etc. have fallen one after another. What’s more, according to media reports, Brazilian President Jair Bolsonaro has been diagnosed with the new coronavirus. Facts tell us that the turning point of the epidemic has not yet occurred!
Masks are still a necessity in the market, and similarly, core meltblown cloth is a scarce resource!
As far as the market situation of melt-blown cloth is concerned, Korean companies are the biggest beneficiaries. “Because at that time, many small factories and small machines exported melt-blown cloth to Europe and the United States, and the quality was very poor. So Europe and the United States The country now doesn’t buy Chinese flannel and masks. So they don’t believe in this piece if no one has dismantled it, but they buy it wherever they go, including in South Korea,” a person familiar with the matter reported.
It can be seen that the meltblown cloth market is not “cool”. The important thing is to improve product quality and break the “priceless” trend of China’s meltblown cloth. The strange phenomenon of “market” is based on product quality.
