Description
Technical field
The utility model relates to multilayer materials field, be specially adapted to medical treatment and with the product scope that directly need contact with human body skin, particularly relate to a kind of laminating condensation material.
Background technology
In medicine equipment, outdoor exercises field, for the material directly or indirectly contacted with human body skin, as lung ventilator headgear, vamps of sport shoes, shoe-pad etc., the material layer compound of multilayer different performance is usually adopted to make.At present, the common laminating condensation material being mainly textile-sponge-textile with the composite material that human body skin directly or indirectly contacts, and attaching process is mainly divided into two kinds: fire pastes and sticker.
Fire paste be a kind of by even flame ground calcination sponge, make sponge top layer reach molten condition after, by textile and the smooth attaching process pressed together of sponge melting layer.Sticker is the technique being bonded sponge and textile material, heat-treated simultaneously each layer of fitting by glue or glued membrane.Adopt this two kinds of attaching process, respond well composite material of fitting can be obtained.But, also there is many limitation, be mainly manifested in the following aspects:
First, adopt fire to paste or the composite material prepared of sticker, owing to there is year glue-line or sponge surface melting or one deck hard melting face can be formed after heating, the gas permeability effect of material is affected, affect the comfort level of product, and then limit the application of product;
Secondly, adopt the composite material that fire pastes or prepared by sticker, because layers of material fits tightly together, carrying out in the die-cut edge sealing processing procedure of ultrasonic wave, inner layer material such as sponge participates in edge sealing together with superficial layer, causes inner layer material degree of participation high, causes edge of materials to harden, affect the comfort level of product, and then limit the application of product;
Secondly, due to large, the required production equipment energy consumption of fire pastes, sticker prepares composite material production complexity, complex operation, manpower demand greatly, cause the production cost of composite material high; And fire pastes or sticker is prepared composite material and easily caused environmental pollution, therefore not environmentally;
In addition, non-woven fabrics, textile material etc. do not paste by fire, sticker mode is fitted, and causes the development of composite material to be restricted.
Utility model content
The purpose of this utility model is to provide a kind of laminating condensation material, is intended to solve that the edge that the composite material prepared of prior art occurs hardens, poor air permeability, complex manufacturing, cost are high and problem not environmentally.
The utility model realizes like this, a kind of laminating condensation material, comprise the superficial layer, bottom surface layer and the sandwich of layers that set gradually, described laminating condensation material is distributed with edge sealing hole, the wall surface of the hole in described edge sealing hole has welding edge sealing ring, described superficial layer is connected by described welding edge sealing ring with described bottom surface layer, and described superficial layer, sandwich of layers and bottom surface layer are by the laminating of described edge sealing hole.
The laminating condensation material that the utility model provides, first, described laminating condensation material is distributed with edge sealing hole, improves the gas permeability of described laminating condensation material, improve the comfort level of product;
Secondly, described superficial layer is connected by described edge sealing hole with described bottom surface layer, and described superficial layer, sandwich of layers and bottom surface layer are fitted by described edge sealing hole, on the one hand, the stable laminating of described superficial layer, sandwich of layers and bottom surface layer can be ensured, prevent described laminating condensation material from dislocation and distortion occurring; On the other hand, described superficial layer, sandwich of layers and bottom surface layer are linked together by described edge sealing hole by the utility model, the site area occupied due to edge sealing hole described in described laminating condensation material is less, therefore, follow-up carry out ultrasonic wave die-cut edge sealing process time, the degree of participation of fusion sandwich of layers can be reduced significantly, effectively improve edge sealing harden problem, obtain overall soft edge sealing effect.Concrete, when edge sealing position is positioned at outside described edge sealing hole, smooth, soft edge sealing effect can be obtained; When edge sealing position is through described edge sealing hole, only there will be the edge sealing effect of out-of-flatness, band edge sealing ring at described edge sealing hole place, thus the overall edge sealing effect of described laminating condensation material is improved significantly.
Again, laminating condensation material described in the utility model, described sandwich of layers can select the Rotating fields of various material, and the product scope of laminating condensation material can be expanded, as described in superficial layer and/ground floor adopt textile layer or layer of nonwoven material; Described sandwich of layers optionally adopts sponge, textile material, leather substance, plastic material, nonwoven cloth material, silica gel material etc.
In addition, the setting in described edge sealing hole, gives the three-dimensional feel that described laminating condensation material is abundant, makes product have more characteristic.
