Shima Seiki Releases Data for Several More Knitted Masks

In light of the worldwide shortage of surgical masks due to the continuing spread of COVID-19 coronavirus, Shima Seiki Mfg., Ltd. has released knitting data for nine more versions of knitted masks to be produced on a variety of its computerized knitting machines.
These are in addition to the various mask data the company has been releasing since March 19th, bringing the total number of versions of the masks to nineteen.
Data released this time consists of cotton masks to be produced on both WholeGarment machines as well as conventional shaping machines. One type of WholeGarment mask data is meant for production on SWG041N2, SWG061N2 and SWG091N2 models, as well as on the rest of its compact WholeGarment Mini machines that are suited for the production of small accessory items, in 15 gauge.
Another type of WholeGarment mask data is meant for production on the MACH2XS series flagship knitting machines featuring four needle beds, in 15L. Shaped knitted mask data is meant for production on SVR093SP as well as the rest of Shima Seiki’s computerized knitting machine lineup equipped with the moveable sinker system, in 14 gauge.
Users with machines that match the above criteria can download the mask data from the Shima Seiki Users’ Site. By releasing mask data for a range of different machines, the company aims to alleviate the shortage of masks as much as it can by allowing production of masks by as many of its customers as possible. With this release smaller sizes for children have now become available as well, in three sizes.
Each of the masks whose data is released this time is a 3D form-fitted mask providing superior fit and comfort. Integral ear straps that are knitted along with the mask portion reduces stress on the ears, and require no further sewing for quick response production. A filter-pouch is knitted-in for inserting commercially available virus filters and other filtration fabrics. Holes are also knitted-in for insertion of wires that provide further adjustment for improved fit.
The knitted cotton masks can be washed and reused repeatedly. It should be noted however that unlike common nonwoven surgical masks, knitted masks do not have virus- and pollen-filtration functionality. Their main use is for the prevention of spray from coughing and sneezing, and for reducing exposure to allergens.
