Embodiment Construction

[0019] The invention provides a highly elastic non-woven fabric, which utilizes the characteristics of thermoplastic polyurethane elastomer, which has the advantages of high elasticity, small deformation, and good air permeability, and has been widely used in clothing and hygienic materials , sports materials, etc., the thermoplastic polyurethane elastomer is formed into an intermediate fiber layer by hot-melt method, and the upper surface layer or the lower surface layer are respectively attached to the upper and lower surfaces of the intermediate fiber layer. The upper and lower surface layers can be made of wool fiber and / or Or wood pulp fiber, such a non-woven fabric has better elasticity and other properties are preserved, and is suitable for fields that require better elasticity.

[0020] see figure 1 , showing the high elastic nonwoven manufacturing equipment of the present invention, the manufacturing equipment comprises:

[0021] Hot-melt device, this hot-melt device...

Abstract

The invention relates to a non-woven fabric and the manufacturing field of the non-woven fabric, and particularly relates to a high-elasticity non-woven fabric and manufacturing equipment of the high-elasticity non-woven fabric and manufacturing equipment. The non-woven fabric contains a middle fiber layer, an upper surface layer and a lower surface layer, and is characterized in that the middle fiber layer is formed by a thermoplastic polyurethane elastic body through a hot melting method; the upper and lower surface layers are made of wool fibers and / or wood pulp fibers. According to the high-elasticity non-woven fabric and the manufacturing equipment of the high-elasticity non-woven fabric, the manufacturing equipment comprises a hot melting device, a first transporting device, a gluing device, a high-pressure device and a molding device. The non-woven fabric woven by the equipment has the advantages of good elasticity, distinct gradation and convenience for manufacturing.

Description

technical field [0001] The invention relates to the field of nonwoven fabric and its manufacture, in particular to a highly elastic nonwoven fabric and its manufacturing equipment. Background technique [0002] Non-woven fabrics are made of raw materials including chemical fibers and plant fibers under the condition of water or air as the suspension medium. Although they are called cloth, they cannot be woven. Non-woven fabrics are a new generation of environmentally friendly materials with good strength. , Breathable and waterproof, environmental protection, flexible, non-toxic and tasteless, and cheap, with the characteristics of water repellency, breathable, flexible, non-combustible, non-toxic and non-irritating, rich colors and so on. If the material is naturally decomposed outdoors, its longest lifespan is only 90 days, and it decomposes within 8 years when placed indoors. It is non-toxic, tasteless, and has no remaining substances when burned, so it does not pollute t...
