Description
Technical field
The utility model relates to a kind of layer compound that make and possesses the structure that bidirectional elastic extends.
Background technology
On deserted consumer articles for use market; For example: disposable diaper, babies learn trousers, and other deserted amenities etc.; The demand that promotes fit and comfort level is arranged always; Therefore, have high flexibility, high flexibility response rate and highly breathable property the layer compound be the product that satisfies this demand.Expect also that generally elastic laminate can be towards the twocouese elastic stretch.Deserted personal-care supplies and health care articles for use have gas permeability usually and sufficient intensity goes to deal with general normal use.Gas permeability is meant the degree that can see through gas or aqueous vapor; And intensity is relevant with pull resistance.Though can promote the extensibility of the polymer film of each layer compound in theory respectively, must be to adopt the percentage elongation better material, so that improved material cost.Therefore, for a long time, there is the elastic laminate that possesses good strength and elastic extension rate simultaneously to make the demand of personal-care supplies, health care articles for use etc. always.
The known mode that makes adhesive-bonded fabric produce unidirectional elastic extension character is that the cloth material is bestowed the fibre structure that reprocessing behind the pretension of single direction destroys the cloth material earlier, the cloth material is bounced back naturally after discharging pulling force then, and then formation possesses the adhesive-bonded fabric of unidirectional elastic extension.
Known adhesive-bonded fabric with bidirectional elastic extension character; Then be on the adhesive-bonded fabric basis of aforementioned unidirectional elastic extension; One side at adhesive-bonded fabric combines one to have the elastic membrane of bidirectional elastic extension character and constitute one deck compound, makes this layer compound have the character that bidirectional elastic extends.But, in conjunction with after elastic membrane as the surface of layer compound one side, with making that the sense of touch of layer compound is not good, also let the people use after when manufacturing clothing or article next to the shin and feel uncomfortable.
The utility model content
The purpose of the utility model is to solve the known adhesive-bonded fabric that bidirectional elastic extends character that has, and combines one to have the elastic membrane that bidirectional elastic extends character in the one side of adhesive-bonded fabric, has the layer compound that bidirectional elastic extends character and constitute one; Cause utilize this layer compound manufacture sense of touch behind clothing or the article next to the shin not good, use uncomfortable problem.
The characteristic of the utility model is to combine two-layer elastic webs layer material in an elastic membrane, by two-layer elastic webs layer material elastic membrane is coated, and avoids elastic membrane to expose and causes sense of touch not good.
Another feature of the utility model then provides the two-layer elastic webs layer material that has unidirectional elastic extension character respectively; When utilizing this two-layer elastic webs layer material to be incorporated into elastic membrane; Make the elastic extension direction of two-layer elastic webs layer material vertical each other; Collocation possesses elastic membrane formation one deck compound that bidirectional elastic extends, and lets this layer compound have more excellent bidirectional elastic and extends character.
Based on this; The technological means of the utility model is to combine one first unidirectional elastic webs layer material and one second unidirectional elastic webs layer material respectively on the relative two sides of a two-way elastic membrane; And the elastic extension direction of this first unidirectional elastic webs layer material is vertical with the elastic extension direction of this second unidirectional elastic webs layer material, and the coefficient of elasticity of this first unidirectional elastic webs layer material and the second unidirectional elastic webs layer material is lower than the coefficient of elasticity of this bidirectional elastic film; Layer compound by aforementioned structure constituted has the character that bidirectional elastic extends.
Said elastic membrane is a kind of elastopolymer; It can be provided with air-vent or air-vent is not set, when air-vent is set, with the character that promptly has the air penetration of letting after said unidirectional elastic webs layer material combines; After manufacturing clothing, comparatively comfortable when wearing.

The specific embodiment
Those skilled in the art below cooperate Figure of description that the embodiment of the utility model is done more detailed explanation, so that can implement after studying this specification carefully according to this.
As shown in Figure 1, elastic laminate 1 structure of the two-way extension of the utility model includes one first unidirectional elastic webs layer material 11, one second a unidirectional elastic webs layer material 12 and a two-way elastic membrane 13; Wherein, the first unidirectional elastic webs layer material 11 and the second unidirectional elastic webs layer material 12 can adopt United States Patent (USP) the 6th, 746, the elastic non-woven cloth that is disclosed for No. 978.Wherein, the first unidirectional elastic webs layer material 11 has unidirectional elastic extension character (as shown in Figure 2) at directions X; The second unidirectional elastic webs layer material 12 has unidirectional elastic extension character (as shown in Figure 3) in the Y direction; 13 of bidirectional elastic films all have elastic extension character (as shown in Figure 4) at directions X and Y direction.The utility model is incorporated into the first unidirectional elastic webs layer material 11 and the second unidirectional elastic webs layer material 12 respectively on the relative two sides of bidirectional elastic film 13 and constitutes posterior limiting compound 1 (like Fig. 1 and shown in Figure 5); Wherein, The elastic extension direction of the first unidirectional elastic webs layer material 11 is vertical with the elastic extension direction of this second unidirectional elastic webs layer material 12, and the coefficient of elasticity of the first unidirectional elastic webs layer material 11 and the second unidirectional elastic webs layer material 12 is lower than the coefficient of elasticity of this bidirectional elastic film 13.In addition, bidirectional elastic film 13 can also be provided with a plurality of air-vents 131 in advance before combining the first unidirectional elastic webs layer material 11 and the second unidirectional elastic webs layer material 12, made layer compound 1 after the combination possess ventilative character.
Said bidirectional elastic film 13 is a kind of elastopolymers, and its elastopolymer that comprises accounts for the optimal proportion of this bidirectional elastic layer compound 1 should be greater than 15% percentage by weight.The said first unidirectional elastic webs layer material 11 or the second unidirectional elastic webs layer material 12 combine with bidirectional elastic film 13; Can behind both involutory surface coating viscoses, carry out gluing, or both involutory backs adopt ultrasonic applying, heating and pressurizing applying, discharge applying, electron beam applying, electrostatic technique or chemical catalyst to fit; Also can utilize blown film, extrude casting film-forming, foaming film forming or directly drench the film mode elastopolymer is coated the first unidirectional elastic webs layer material 11 or the second unidirectional elastic webs layer material, 12 surfaces.
