TESTEX Textile Test Instrument

APL250 mask manufacturing machine has a high-Speed capacity of 250 Pcs/min. Differs to traditional earloop type mask making machine, this one-process mask forming machine does not need an ear loop welding machine to save labor costs materials to finish in one set of machines. Materials In, Masks Out In One Set of Mask Production Machine ONLY! No More Earloop Welding Machines.

Friction : friction refers to the effect of hindering the movement on the contact surface when there is a relative motion or relative movement trend between two objects in contact with each other. Friction can be divided into sliding friction and rolling friction. Abrasion : abrasion refers to the wear and tear caused by friction during the use of the object, thus reducing the user experience of the object and shortening the service life of the object. The main manifestations of abrasion are fading, pilling, cracks, peeling, slurry, and so on. Friction is the most common and unavoidable cause of wear and tear in textile and related industries. Study the friction properties of fabrics, leather, rubber and other materials has important reference significance for improving the abrasion resistance of articles and how to select the raw materials suitable for our needs. Take fabric as an example, abrasion is the phenomenon of damage that when the fabric does repeated friction with other obje...

Whether you have already started a mask factory or are preparing to start one, if you want to manage efficiently and produce face masks that meet the standard requirements, then the following information, processes and requirements will help you, mainly in the following 5 areas. Raw materials for mask factory production Workshop & equipment and production process Mask testing and premarket requirements The structure and principle of the face mask The main risks of mask production Raw materials for mask factory production The products produced by the mask factory are masks, which are generally composed of the following materials. Main material: common medical mask or protective mask, mainly composed of three layers of non-woven fabric. The inner layer is ordinary non-woven fabric; the outer layer is made of non-woven fabric with waterproofing treatment, mainly used to isolate the liquid sprayed by the patient; the middle filter layer with is meltblown non-woven fabric (some after el...

Since the COVID-19, many companies and the populace are concerned about N95 masks, and this article talks to you about the certification of N95 masks. First, let’s take a look at the U.S. regulatory body for masks (respirators).   In simple terms, NIOSH is responsible for the certification of personal protective respirator N95, FDA is responsible for the registration audit of medical masks, and medical N95 masks are certified and registered by two agencies.   NIOSH Certification Authority N95 is called Respirator in English, now it is called N95 mask in COVID-19, which is actually very different from ordinary masks. The National Institute for Occupational Safety and Health (NIOSH) and the National Personal Protective Technology Laboratory (NPPTL) are the agencies specifically responsible for respirator product certification.   NRP Series According to the US Federal Code 42 CFR part 84, NIOSH classifies anti-particle masks into 3 series of 9 categories. Classification N se...
