Contec offers an intensive line of non-woven dry wipes designed to meet the requirements of some of the most critical environments on the earth. We take delight in growing innovative merchandise that not only deliver excellent efficiency but are also value-efficient for our customers.

These non-woven fiber wipes are link free and can be used several instances per connector leading to a really low cost per connector cleansing ratio. Surgical masks are made up of a multi-layered structure, usually by covering a layer of textile with non-woven bonded material on either side. Non-wovens, which are cheaper to make and cleaner because of their disposable nature, are made with three or 4 layers. These disposable masks are often made with two filter layers efficient at filtering out particles corresponding to bacteria above 1 micron.

Cellulose is more absorbent, whereas polyester is much less linting. Polycellulose blended wipes are one of the popular cleanroom wipes for basic wipedown and spill management in ISO Class 6 and above cleanrooms. Biodegradable and naturally ESD friendly, polycellulose supplies some of the economical cleanroom wiper choices because it’s straightforward to produce and course of. Price, chemical resistance, and excessive absorbency are among its most desired options.

USP 797 compliance requires each initial and continued application of isopropyl alcohol all through a cleanroom session. All disinfectant, either sprayed or wiped, should be allowed to dry with respect to the producer’s instructions or printed information for minimal contact time.

Generally, IPA (70% isopropyl alcohol) remains on surfaces to be disinfected for no less than 30 seconds before CSP packaging resumes. Ultrasonically sealed wipes impart an ultrasonic warmth process which melds fibers without the need for cutting by knife or the carbon deposit of laser cuts. The result is a cleanroom wipe with decrease carbon levels, and a precisely formed, secure edge. Ultrasonically sealed wipes present the best grade of particle retention and the most cleanliness. The mixture of cellulose and polyester may vary as the majority depending on the necessity of absorbance versus less lint.

The filtration level of a masks, however, is determined by the fiber, the way in which it’s manufactured, the net’s construction, and the fiber’s cross-sectional form. Masks are made on a machine line that assembles the nonwovens from bobbins, ultrasonically welds the layers together, and stamps the masks with nose strips, ear loops, and different items. Surgical face masks are made with non-woven cloth, which has higher micro organism filtration and air permeability while remaining less slippery than woven cloth. The materials most commonly used to make them is polypropylene, either 20 or 25 grams per square meter in density.
