Needle felt after the insulation was "needle felt" is broken with the old line (cloth) and other materials must be treated by re-pressed, and low cost, good insulation properties. Needle felt needle felt insulation was used as the primary insulation was kind of cold insulation material, (you can also use aluminum film on one side and white polyester fabric sewn fabric cooperation), the use of suture material. This insulation was to be heavier than their own weight composite insulation, wind performance and better insulation properties. Its biggest drawback is that the water is poor. But if the show to spend Oxford waterproof cloth, made of water-resistant insulation can be, the other, before the insulation is retractable to save, you need a large space to dry, you can save only after dry. As a non-woven non-woven needle shed, both breathability and insulation, fruits and vegetables in the nursery have played a positive role. Here is the introduction to the specific characteristics of non-woven fabrics shed: 1, light weight: the polypropylene resin as the main raw material, the proportion of only 0.9, only three-fifths of cotton, with fluffy, feel good. 2, soft: the fine fibers (2-3D) tap hot-melt adhesive molding. Finished insulation was moderate softness, with comfort. 3, water repellent, breathable: Polypropylene slice non-absorbent, moisture zero, finished good water-repellent, made of 100% fiber insulation is composed of a porous manufacturers address, permeability, easy to maintain the fabric dry, easy to wash. 4, non-toxic, non-irritating: product is in compliance with FDA food-grade raw material production, without other chemical composition, performance insulation is price stability, non-toxic, odorless, does not irritate the skin. 5, anti-bacterial, anti-chemical: Polypropylene is a chemical substance blunt, no insects, and can isolate the bacteria and insects liquid erosion exist; antibacterial, alkali corrosion, erosion and the finished product is not due to the impact strength.
