Because waterproof insulation is needed every day by Uncovery insulation, frequent reel and pull the insulation quilt work, resulting in a needle is too large, then the needle is too large have risks? Today, we briefly introduce. Waterproof insulation at the eye of a needle will be seepage, if it rains or snows weather, rain and snow will be very easy to enter into the waterproof insulation insulation core is allowed to damp insulation core and reduce its insulation properties, and some of the materials are waterproof insulation material is waterproof, so water entering the insulation core can not be discharged through the eye of a needle. So easy to make long-term use waterproof insulation was lost due to damp thermal insulation properties are wholesale, affecting the normal growth of the crop. There are many non-woven classification, today Xiaobian to introduce simple non-woven according to the classification of the production process: First, the heat sealing nonwoven thermal bonded non-woven fibrous or powder refers to join in on the web hot-melt adhesive reinforcement materials, fiber network and then melted by heating cooling reinforcement into cloth. Second, non-woven non-woven needle acupuncture is a dry non-woven, non-woven fabric is the use of acupuncture needles puncture the insulation effect carts were the fluffy fiber mesh reinforcement into cloth. Third, airlaid nonwoven airlaid nonwoven fabrics can be called airlaid, airlaid nonwovens. It is the use of airlaid pulp fiber technology will loosen the fibers into a single state, and then the fiber agglutination method using flow on a net curtain, fiber network and then reinforcement into cloth. Four, wet nonwoven wet nonwoven fabric is placed in an aqueous medium fiber material fibers into a single opening, while the different fiber raw materials are mixed, formed into a fiber pulp suspension, the pulp suspension fed to the laying means, the fibers In the wet state into a network and then reinforcement into cloth. Thermal insulation was being wholesale _ _ Canton St. agricultural machinery provided by the Canton of St. Shouguang Agricultural Machinery Co., Ltd .. Shouguang City, Canton St. Agricultural Machinery Co., Ltd.
