Description of the invention (1) Technical Fan Ye Weaving cloth. Background Art In order to increase the use of non-woven fabrics, various characteristics of non-woven fabrics need to be given. One of them is superior air permeability and water resistance. In essence, breathability is the opposite of water resistance. This requires a large number of through holes extending from the front surface to the rear surface of the nonwoven fabric in the nonwoven fabric to improve its air permeability, but inevitably reduces the water resistance while improving the air permeability. When non-woven fabrics are used for medical purposes such as surgical gowns, they need to have a large: bacterial barrier, that is, a large water resistance is required to prevent infection of the wearer. In addition, when the clothes are deformed by bending or compression, it is necessary not to allow blood or the like to permeate through the nonwoven fabric. The superior breathability is the requirement to minimize sweat stains and not to accumulate moisture. A combination of two different fabrics has been proposed to match the mutually contradictory properties, breathability and water resistance. For example, Japanese Unexamined Patent Announcement (Kokai) No. 64 — 61555 shows a manufacturing technology of composite board, which spreads a dispersion liquid including two short fibers with different fineness on a shrinkable knitted fabric and injects water In the flow, the short fiber itself is fully interwoven and interwoven in the knitted fabric. This kind of composite board has excellent air permeability, but the composite board has poor water resistance.

Invention Instructions (4) Short fiber arrangement On the surface of the composite nonwoven fabric that is quite parallel, and the short fibers in the short fiber nonwoven fabric A and the filaments in the filament nonwoven fabric B are interwoven only at the interface between them, in addition, the short fiber nonwoven fabric The short fibers in the cloth A are not deeply embedded in the filament nonwoven cloth B. In the conventional composite nonwoven fabric shown in FIG. 3, the short fibers 21 constituting the short fiber nonwoven fabric C 1 are deeply embedded in the fibrous nonwoven fabric D by a columnar liquid flow under high pressure, so the short fibers -21 are The filaments constituting the filament nonwoven fabric B are highly interwoven. Therefore, although the composite non-woven fabric shown in FIG. 3 is formed of two types of non-woven fabrics, the resulting composite non-woven fabric has a structure similar to a single non-woven fabric formed by mixing staple fibers 21 and filaments 2 2. Exterior. The first feature of the composite nonwoven fabric of the present invention is the sum of the short fiber ratio F of 0.3 denier or less and the short fiber ratio G of 0.5 denier or more in the short 50% by weight or more in fiber nonwoven A, the ratio of F / G is 1 to 7 or more and 4 to 3 or less, and the weight per unit area of short fiber nonwoven A is 10 g / tn2 and 40 g / m2. The fineness of the short fiber 11 is 0.3 denier or less, preferably 0.15 denier or less, _001d or more. Not all staple fibers need to have the same fineness. Staple fibers 11 can be made by cutting fibers, for example, sea-island fibers to separate sea components, composite fibers with two or more components, or direct spinning Superfine fibers obtained by silk and other methods. The fineness of the short fiber 12 is 0.5 d or more, preferably, 0.75 denier or more and 10 denier or less. Not all staple fibers 1 2 need to have the same fineness, but the fiber length of the staple fiber 1 1 is preferably greater than the thickness of the composite nonwoven fabric, but the staple fiber 11 and staple fiber 12 do not need to have this paper ruler and General China S home quasi (Cfs \ S) A 4 specifications (210 X 297) &quot; ~ '' ------------------ ~ ------- installed- ----- Order (please read the precautions on the back before writing this page) 219953 A6 _____B6_ printed by S Industry and Consumer Cooperative of Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention description (5) The same ray length. Staple fiber 1 1 improves the water resistance of the composite nonwoven fabric, but when the content of staple fiber 11 in all staple fibers of the short fiber nonwoven fabric A increases, the air permeability decreases. The short fiber 12 has the opposite function of the short fiber 11. Therefore, when the F / G is 1 to 7 or more and 4 to 3 or less, the staple fibers 11 and 12 have an excellent balance, and thus the composite nonwoven fabric obtains excellent air permeability without reducing water resistance. However, the sum of F and G needs to be 50% by weight or more and when the sum of F and G is less than 50% by weight, it is difficult to obtain a superior effect. Therefore, the sum of F and G is preferably 70% by weight or more. The weight per unit area needs to be 10 g / m2 or more and 40 g / γ2 or less. When the weight per unit area exceeds 40 g / m2, the air permeability of the composite nonwoven fabric decreases and when the weight per unit area is less than 10 s / m2, the water resistance of the composite nonwoven fabric decreases. The apparent density of the short fiber nonwoven fabric A is preferably 0.1 g / m 2 to improve the water resistance of the composite nonwoven fabric. The method of measuring the apparent density of the nonwoven fabric is described below. The second characteristic of the composite nonwoven fabric is that the average orientation degree of the short fibers in the short fiber nonwoven fabric A is 2. ◦ or more and 1 ◦ or less. The average degree of orientation Z is the ratio between the component parallel to the surface of the filament nonwoven fabric B and the component perpendicular to the surface of the filament nonwoven fabric B in the short fibers of the staple fiber nonwoven fabric A. The method of measuring the average orientation is described below. The inventor of the present case discovered that the leakage caused by the deformation caused by bending and compressive force in the composite nonwoven fabric is determined by the value of the average degree of orientation Z. Figure 6 shows the relationship between the average orientation of staple fibers and the water resistance between non-woven fabrics (please read the back of the page-matters needing attention, and then re-enter this page)-binding. Ordering.-Thread. Clothing paper size Mao General China National Standards (CNS) A 4 specifications (210 X 297)-7-81.9.25,000 219S58 A6 B6 The Ministry of Economic Affairs Central Bureau of Industry and Commerce Co-operative Cooperatives printed and issued five, the description of invention P) Department of the drawing. As shown in Fig. 6, there is clearly a linear relationship between the average orientation Z of short fibers and the water resistance of nonwoven fabrics having the same composition and weight per unit area. Even if the composite non-woven fabric is subjected to flexion or compression, it can still effectively prevent liquid leakage and obtain a composite non-woven fabric with excellent water resistance. When the average degree of orientation Z exceeds 10, the interweave between the short fibers constituting the short fiber nonwoven A and the interweave between the short fiber nonwoven A and the filament nonwoven B is reduced, so that the strength of the composite nonwoven reduce. Therefore, it is necessary to make the average orientation degree 2.0 to 10, preferably 2.3 to 10, and 2.5 to 8.0. The third feature of the composite non-woven fabric of the present invention is that the non-woven fabric B is embedded into the filament non-woven fabric in the area of the random cut surface of the composite non-woven fabric with a length of 5000. The number of short fibers N which is 1/2 or more of the thickness is 2 0 or less. The measurement method of N is described below. When N exceeds 20, the water resistance of the composite nonwoven fabric decreases. As described above, the subject of the present invention can be achieved by integrating the short fiber nonwoven fabric A and the filament nonwoven fabric B with a special structure. The nonwoven fabric produced by the spunbond method can be used as the filament nonwoven fabric B. The filaments constituting the filament nonwoven fabric B are partially bonded to each other by hot melt or using an adhesive to fix their structure. Since the bonding portion in the filament nonwoven fabric B cannot interweave with the short fibers in the short fiber nonwoven fabric A, the total area of the bonding portion is preferably 2% to the area of the total surface area of the filament nonwoven fabric B Between 20%, and preferably 0.5 denier filaments, when the average value of the elongation at break measured in two directions at right angles is 40% or less, the two nonwoven fabrics are interwoven Short fiber can easily fit the above arrangement. --- ^ -------------- ------- installed ------ ordered (know first read the note for the back * &quot; item again.

Description of Invention (7) Any fiber can be used in the composite nonwoven fabric of the present invention. For example, thermoplastic resins such as polyamide fibers, polyester relay fibers, polyolefin fibers, polyacrylonitrile fibers, etc., acetate fibers, regenerated cellulose fibers, and the like can be used. In addition, if necessary, natural cellulose fibers, wool strands, etc. can be used, and when regenerated cellulose fibers are used as short-fiber nonwoven A, the trajectory and openings of water jets used for interweaving can be Easy to remove, thus preventing the water resistance from decreasing. When the polyester fiber is used in the short fiber nonwoven A, the interweave of the fiber nonwoven B and the short fiber nonwoven A is added. Therefore, when the ratio of polyester fibers is 1 to 3 or more and the ratio of regenerated cellulose fibers is 1 or less, the color retention obtained as a result of using regenerated cellulose fibers and polyester fibers can be obtained. In addition, except for staple fibers with a fineness of 0.3 denier or less and staple fibers with a fineness of 0.5 denier or more, all of the staple fiber nonwoven fabrics are preferred Use fibrillar pulp-like fibers between 5% and 15% by weight to obtain a composite nonwoven fabric with water resistance and tensile strength that is slightly improved, but does not reduce breathability. Fibrillated pulp sticky fibers can be obtained by combating natural pulp sticky or tearable acrylic fiber. The manufacturing method of the composite nonwoven fabric of the present invention is described below. Disperse the predetermined mixing ratio ◦. 3 denier or smaller staple fiber and 0.5 denier or larger staple fiber in water, and split the dispersion into paper to obtain staple fiber nonwoven A. In this case, it is better to add a surfactant to the dispersion to improve the dispersibility of the fiber in water. Next, a layer B of fibrous nonwoven fabric produced by the spunbond method was laid on the staple fiber nonwoven fabric A.

In addition, because of poor resistance to liquid leakage when deformed due to bending or compressive forces, the composite nonwoven fabric has excellent preventive ability for blood penetration during compression by the operator on the operating table, for example It is breathable, so it does not accumulate humidity, and the strength of the composite nonwoven fabric is excellent in flexibility. The above characteristics of the composite nonwoven fabric of the present invention can be explained by the holding properties of the composite nonwoven fabric of the other and Comparative Examples 1 to 9. For example, in Comparative Examples 1, 4, 5, 7, 8, and 9, the N value is large, but the average orientation is small, and the ratio of short fibers of 0.3 denier or more in the short fiber nonwoven A is in comparison. Example 2 is large and is small in Comparative Example 3. Therefore, the former has poor air permeability and the latter has poor water resistance. In addition, since the weight per unit area of the short fiber nonwoven fabric A is too large in the composite nonwoven fabric of Comparative Example 6, the air permeability is poor and the short fiber nonwoven fabric A and the filament nonwoven fabric of this composite nonwoven fabric are poor Insufficient interweave between B. The apparent density of the short fiber nonwoven fabric A in Examples 1 to 15 was 0.1 kg / cm3 or less. However, in Comparative Examples 1, 5 and 9, the short fiber A nonwoven fabric A having a small average orientation Z value has an apparent density of less than 0.1 g / cm 3. The composite nonwoven fabric of the present invention can be used for medical applications, such as Surgical gowns, drapes, drapes, face masks, etc., can also be used as physiological pads and toppers for diapers.
