What Is Fabric Air Permeability Tester

      Automatic air permeability tester can quickly and accurately assess air permeability of various materials such as wovenfabrics, knitted fabrics, non-woven fabrics, industrial filter materials, as well as paper and foam products.                         air permeability tester , to test the resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area.                                The specimen is loaded to the test area of the    Automatic air permeability tester  easily by means of an automatic holder. By pressing down the holder to start the test. Aih’jr permeability tester equipped with a vacuum pump to draw air through an automatic interchangeable test head with a circular opening. The pre-selected test pressure is automatically maintained, and after a few seconds the air permeability of the test specimen is digitally

Blanket Flammability Tester Method

     Specimens cut from the blanket fabric are prepared by brushing if they have a raised fiber surface and by drying. The dried specimen is held in a special apparatus, a standardized flame is applied to the surface for a specified time under controlled conditions, and burning, charring, or discoloration of a paper monitor is noted. Two classes of flammability are described.      This test method of  Blanket Flammability Tester  should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.A burn of sufficient intensity to discolor a paper m

Gloves Cutting Resistance Testing Machine For Gloves manufacturers

      Cut-resistant gloves are designed to protect hands from direct contact with sharp edges such as glass, metal, ceramics and other materials. Cut resistance is a function of a glove’s material composition and thickness.You can increase the level of cut protection by increasing material weight ; by using high-performance materials such as Dyneema , Kevlar , and metal mesh; or by using composite yarns made with varying combinations of stainless steel, fiberglass, synthetic and high-performance yarns.            Performance characteristics of    Cut-resistant gloves  are not only affected by a material’s weight, but also by the coatings applied to the outside surface. Lighter-weight styles offer more dexterity, resulting in less hand fatigue, while their heavier counterparts generally provide more cut and abrasion protection. Coated gloves enhance grip, especially on slippery surfaces. However, some coated gloves may not be appropriate for some applications, i.e. food handling.
