Definitions
- the present invention relates to a urethane foam reinforcing material used for a seat or the like, and more specifically, a frictional force with a metal spring or the like, effectively protecting the urethane foam, and having excellent handleability and large unevenness.
- the present invention relates to a urethane foam reinforcing material that can be applied to a urethane molded body. Background art
- a foamed urethane molded body has been widely used as a cushioning material for seats and the like, and generally, a reinforcing material integrated with a foamed urethane molded body is used.
- a reinforcing material is located between the urethane foam molded body and the metal spring, and plays a role of protecting the foamed urethane molded body from the friction that receives the metal spring force as well as uniformly dispersing the cushioning action of the metal spring. It is.
- As the quality demanded by consumers increases there is an increasing demand for eliminating the scratching noise caused by the friction between urethane and metal springs that ooze into the reinforcing material when seats are used.
- a reinforcing material that has a high layer and a dense layer and prevents the seepage of urethane in the dense layer has been proposed (see, for example, Patent Document 1 and Patent Document 2).
- a reinforcing material has poor moldability during foamed urethane molding
- the use of foamed urethane having a shape with high design and large irregularities, which has been strongly demanded in recent years causes the formation and breakage of wrinkles. Such defects occurred, and there was a problem that the urethane oozes out from this, and breakage occurs due to friction with the metal spring.

- Patent Document 2 JP-A-6-171003
- Patent Document 3 Japanese Patent Application Laid-Open No. 2004-353153
- the present invention has been made against the background of the prior art, and effectively protects the urethane foam molded body, suppresses scratching noise with the metal spring, has high productivity, is excellent in handleability, and has large irregularities.
- the challenge is to provide urethane foam reinforcements that can be applied to molded urethane foams.

Odtex nonwoven fabric A, single yarn fineness 0.5 to 2.5 dtex nonwoven fabric B and force From the direction of nonwoven fabric A- needle density 35-70 pieces / cm 2 at -. one Dorupanchika ⁇ E foamed urethane reinforcing material characterized by being laminated by, (2) a single fiber fineness 1.
- Odtex nonwoven fabric a of the outer layer Urethane foam reinforcement characterized by a three-layer structure with a single yarn fineness of 0.5 to 2.5 dtex non-woven fabric B and laminated by needle punching at a needle density of 35 to 70 Zcm 2 (3)
- the nonwoven fabric A has an initial modulus of 10 to: L00NZ5 cm, elongation of 2 to 50%, and the nonwoven fabric B has an initial modulus of 30 to 200 NZ5 cm and elongation of 5 to 50%
- the urethane foam reinforcing material according to the present invention effectively protects the urethane foam molded article, suppresses the exudation of the urethane, suppresses the scratching noise with the metal spring, and has excellent die punching performance and high productivity. It has the advantage of being easy to sew, excellent in handleability, and adaptable to foamed urethane molded products with large irregularities.
- the urethane foam reinforcing material of the present invention has a single yarn fineness of 1.0 to 3.
- Nonwoven fabric A having an Odtex force and a nonwoven fabric B having a single yarn fineness of 0.5 to 2.5 dtex force are laminated by a one-punch method. It is preferable.
- non-woven fabric A is impregnated with urethane at the time of foaming urethane molding, and non-woven fabric B plays a role of preventing the seepage of urethane. Entangling with B by the one-dollar punch method makes it difficult to peel off, and it is sufficiently impregnated with urethane, ensuring adequate hardness, so that it can be punched easily and accurately. It becomes.
- the single yarn fineness of the non-woven fabric B is 0.5 to 2.5 dtex, it is possible to effectively prevent the seepage of urethane, and the durability against friction with the metal spring is excellent. More preferable non-woven fabric A has a fineness of 1.5 to 2.5 dtex, more preferably 1.8 to 2.3 dtex. Further, the single yarn fineness of the nonwoven fabric B is more preferably 0.8 to 2.2 dtex, and still more preferably 1.0 to 2. Odtex.
- urethane foam reinforcement member of the present invention a needle density 35-70 amino ZCM 2 - is preferably laminated with one Dorupanchikaroe. This is because when the needle density is 35 to 70 / cm 2 , sewing is performed accurately and wrinkles can be effectively prevented during foam molding. That is, if a strong mechanical entanglement is added to the nonwoven fabric A and the nonwoven fabric B in the fineness range, the entanglement is not released at the time of sewing, and the laminate cannot be stretched easily and can be accurately sewed. The inventors of the present application have found that problems such as generation of wrinkles can be prevented because the entanglement is released and the mold extends along the shape of the mold.
- the needle punching process also includes the nonwoven fabric A layer force.
- the urethane foam reinforcing material of the present invention is also one of the preferable forms that has a three-layer structure in which the outer layer is nonwoven fabric A and the inner layer is nonwoven fabric B. With such a structure, the fibers of the nonwoven fabric A penetrate the nonwoven fabric B, and the nonwoven fabrics A of both outer layers are strongly entangled with each other and are difficult to peel off.
- the nonwoven fabric A used for the foamed molding material of the present invention preferably has an initial modulus of 10 to 100 NZ5 cm. If it is within the effective range, it is possible to increase the number of sheets to be stacked in one punching process, improving productivity, reducing variations in the punched mold, and enabling accurate sewing. This is because fiber entanglement becomes strong and it becomes difficult to peel off. More preferably, the initial modulus is 12 to 90 NZ5 cm, more preferably 13 to 80 NZ5 cm.
- the means for obtaining the nonwoven fabric A having the initial modulus physical properties is not particularly limited. If V ⁇ is thermocompression bonded by embossing, it can be obtained by adjusting the thermocompression bonding temperature. If the constituent material is polyethylene terephthalate, it can be obtained by setting the temperature to about 175 ° C to 210 ° C.
- the nonwoven fabric B used for the foamed molding material of the present invention preferably has an initial modulus of 30 to 200 NZ5 cm. If it is within the effective range, it is possible to increase the number of sheets that can be stacked in one punching process, improving productivity, reducing variations in the punched mold, and enabling accurate sewing. Is the same as nonwoven fabric A in the previous term, but it effectively prevents the seepage of urethane.
- a more preferable initial modulus is 33 to 190 NZ5 cm, and further preferably 35 to 180 NZ5 cm.
- the means for obtaining the non-woven fabric B having the initial modulus physical properties is not particularly limited, but can be obtained by adjusting the thermocompression bonding temperature as long as it is thermocompression-bonded by an embossing cage. If the material to be used is polyethylene terephthalate, it can be obtained by setting the temperature to about 190 ° C to 230 ° C.
- the nonwoven fabric B used for the urethane foam reinforcing material of the present invention preferably contains 0.5 to 3% by weight of carbon black.
- the present inventors have also found that the inclusion of carbon black can prevent local seepage of urethane.
- the factors that can prevent local seepage of urethane by including carbon black It is not clear, but it is thought as follows. That is, since the fiber containing carbon black has low frictional resistance, the fiber can be uniformly dispersed during the production of the nonwoven fabric B, and the fiber is opened when Z or polymer is spun and then electrically opened. One of the factors is considered to be that the uniformity of the nonwoven fabric is increased.
- embossing is effective, and the embossed part is almost surely formed into a film, preventing urethane seepage.
- a more preferred amount of the additive is 0.6 to 2.5% by weight, still more preferably 0.8 to 3% by weight.
- the nonwoven fabric used for the urethane foam reinforcing material of the present invention is preferably a hot-embossed spunbond nonwoven fabric.
- Hot-embossed spunbonded nonwoven fabrics have excellent abrasion resistance with less fuzz, and are capable of controlling air permeability and urethane exudation prevention performance with high accuracy.
- the preferred hot embossing conditions for the nonwoven fabric A are a linear pressure of 10 to 40 kNZm and an embossed area ratio of 8 to 30%, and for the nonwoven fabric B, a linear pressure of 20 to 50 kN / m and an embossed area ratio of 8 to 30%.
- basis weight of the nonwoven fabric A used in urethane foam reinforcing material of the present invention is preferably a 30 ⁇ 150GZm 2 Dearuko. If it is 30gZm 2 or less, fiber entanglement will be insufficient, and it will break during the urethane foam process, leading to urethane seepage. If it is 150 gZm 2 or more, the cutting property is deteriorated and the base fabric is difficult to follow the mold during foaming.
- basis weight of the nonwoven fabric B used in urethane foam reinforcing material of the present invention is 20 ⁇ : LOOgZm 2 Dearuko and are preferred. With lOOgZm 2 or higher, needle penetration resistance increases when needles are entangled, causing problems such as needle breakage.
- the product width of the laminated nonwoven fabric is 50mm wide and 200mm long. Measured at a pulling speed of 200 mmZ The average values of 5% elongation stress and tensile strength were defined as 5% elongation stress (NZ5cm) and tensile strength (NZ 5cm).
- a non-woven fabric is attached to the upper surface of the mold on the side of the urethane foam molding mold where there is a foam gas air vent, and foamed urethane resin is added as usual, and polyurethane foam molding is performed under heat and pressure.
- a flexible polyurethane foam in-mold foam molded product was prepared.
- the obtained molded product was cut, the state of the cross section was observed, and the polyurethane foam Measure the joint strength between the layer and the laminated nonwoven fabric.
- thermocompression bonding web having a basis weight 55GZm 2 random loop structure consisting of a polyethylene terephthalate fiber of 2. 5 dtex which is manufactured by a spunbond method in calendering one process by heat rolls 170 ° C 1% random loop made of 2dtex polyethylene terephthalate fiber and laminated with non-woven fabric B which is 40gZm 2 web thermocompression bonded by calendering with a 200 ° C hot roll.
- FPD1-40S made from one dollar-a single layer punched at a density of 50 dollars / cm 2 and a needle depth of 14 mm-gave a two-layer laminated nonwoven fabric.
- Non-woven fabric A had a 5% elongation stress of 15 NZ5 cm and a width of 8 NZ5 cm
- non-woven fabric B had a 5% elongation stress of 41 NZ5 cm and a width of 27 NZ5 cm.
- non-woven fabric A is laminated on both sides of non-woven fabric B, and FPD1-40S made by Organ-using one dollar-density of 50 dollars Zcm 2 and needle depth of 14 mm-punching one dollar, three layers A laminated structure nonwoven fabric was obtained.
- the nonwoven fabric 3 produced under the same production conditions as the nonwoven fabric 1 is layered on the two-sided nonwoven fabric of the two-layer laminated structure obtained in Comparative Example 1, and one dollar of FPD1-40S manufactured by Organ Corporation is used. A dollar density of 40 Zcm 2 and a needle depth of 14 mm was punched for one dollar, and entangled to obtain a three-layer laminated structure nonwoven fabric.
- Table 1 shows the evaluation results of the examples and comparative examples.
- Examples 1 and 2 also have good urethane impregnation properties that do not exude when urethane foamed, and when the peel measurement is performed, the urethane material breaks down. In addition, it was confirmed that no scratching noise was generated by contact between the nonwoven fabric and the panel. In the punching evaluation, it was confirmed that cutting can be performed satisfactorily without fluff and poor cutting. In the sewing evaluation, the stress at 5% elongation was 20 NZ5 cm or more, and it was confirmed that sewing was possible within the allowable dimensions by suppressing the extreme elongation of the nonwoven fabric during sewing work.
- the present invention effectively protects a foamed urethane molded article, suppresses scratching noise with a metal spring, has high productivity, is easy to handle, and can be applied to a foamed urethane molded article having a large unevenness.
- Urethane foam reinforcements can be provided at low cost and contribute to the industry.
