Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
The non-woven material buffer pad with stable resilience for the transport case adopts 3D upright cotton, commonly called upright cotton, also called elastic cotton and vertical elastic non-woven fabric, which is a novel environment-friendly non-woven three-dimensional material formed by combining a group of fibers together by a special method, and is different from the traditional knitting method. The most important characteristics are the arrangement mode and the lapping mode of the fibers. The material has a three-dimensional structure of upstanding webs, such as a sponge. The fiber assembly can obtain the maximum elasticity and compression resistance. The composite material can be recycled, has light weight, strong flame retardant property and wide application prospect, is widely applied to the filling pad materials of bra mold cups, mattresses, sofas, seats and the like, and also can be used as the pad materials of airplanes, high-speed rails, automobile interiors and medical supplies.
The hard cotton is formed by combing polyester fiber with higher hardness and low-melting-point fiber, lapping and uniformly heating and shaping in a drying room. Firm, easy to use, very easy to process. No auxiliary agent or adhesive is added in the production process, so that the product has no pollution, and the material is also regenerated fiber and can be recycled. Is mainly applied to train seat cushion cotton and hard mattress.
The needle-punched cotton is a product which directly punches fibers into flocculus without weaving, and is often used as a garment warm-keeping interlayer. Is easy to process and more convenient to recycle. The use of needle-punched cotton is quite extensive, and besides clothes, the needle-punched cotton is also used as a base material for wall cloth for interior decoration.
The structures of the 3D upright cotton, the common non-woven material (hard cotton, needle punched cotton, etc.), and the sponge (foam) are respectively a three-dimensional fibrous structure, a planar fibrous structure, and a continuous bubble structure, and the characteristics thereof are shown in table 1.

The design principle of the utility model is as follows:
factors influencing the cushioning properties of nonwoven materials: the fiber is characterized in that firstly, the raw materials comprise fibers of different types (such as terylene, chinlon, polypropylene fiber, functionality and the like), secondly, the fibers of the same type have different textures (hollow, sheath-core and the like), different shapes (linear, spiral and the like), different fiber numbers (diameters) and different lengths, and thirdly, the fibers of different types, textures, fiber numbers and lengths are mixed according to the proportion; adding or not adding various low-melting-point materials as binders; producing non-woven materials with different textures (three-dimensional fibrous structure and planar fibrous structure) and different gram weights (weight per unit area) and thicknesses by adopting different processes and different process parameters (lapping mode, lapping thickness, needling density, needling speed and the like).
Design principle of nonwoven cushion pad based on experimental analysis:
the flexible foam polymer material has good rebound stability, and in order to meet the requirement of the rebound stability of the cushion pad, the non-woven material is subjected to a strain-determining cyclic compression test: according to low density (<250KG/m2) Flexible foam polymer compression stress strain characteristic test (reference standard ISO3386/1:1986, flexible foam polymer; measuring stress-strain characteristics in compression; part 1: low-density material), and the thickness value of the test material after the rebound is stable is used as the index for evaluating the rebound performance of the material.
Therefore, be different from current non-woven materials's processing technology, the utility model discloses one of the improvement measure of buffer pad is that three kinds of non-woven materials list base member 3D upright cotton (1a), stereoplasm cotton (1b) or acupuncture cotton (1c) have all increased the utility model discloses unique continuous compression resilience stable technology makes and just can regard as non-woven materials buffer pad base member 1 after the resilience is stable. According to the thickness after the rebound is stable, a continuous multi-roller rolling device is not adopted (the nonwoven materials outside each pair of rolling devices can rebound because the cylindrical roller cannot continuously press), but a self-driven flat belt tensioning type flat pressing device is adopted, and parameters such as the pressure and the duration time of the tensioning flat belt pressing can be adjusted technically, so that the requirement on the rebound stability of the nonwoven material cushion pad is met.

The static damping coefficient is only related to the damping performance and the structural size of the material: c ═ σm/E0Wherein σ ismFor the static stress sigma to which the cushioning material is subjectedm＝Gcmg/A，E0Is the deformation energy per unit volume of the cushioning material. And (3) solving an integral function by utilizing a cumtrapz trapezoid in MATLAB, solving an integral of the stress-strain diagram curve, and calculating the area under the corresponding interval curve to obtain a material buffer coefficient value and a buffer coefficient-static stress curve diagram.
Given the brittleness value Gc of the contents and the falling height h of the contents, the minimum thickness of the selected cushioning material can be calculated: t ═ C × h/Gc. From this equation, it can be seen that when a cushioning material is selected for a content having a certain brittleness value, the thickness required varies depending on the cushioning coefficient C value, provided that Gc and h values are constant and different cushioning materials can bear the maximum static stress.
