Definitions
- the present invention relates to a flexible polyurethane foam suitably used for clothing such as a brassiere pad or a shoulder pad by laminating a cloth and hot pressing the cloth, and a cloth laminating the flexible polyurethane foam to which a cloth is laminated. It relates to a flexible polyurethane foam product. More specifically, the present invention relates to a flexible polyurethane foam having a wet / dry swelling / drying / shrinkage ratio similar to that of a fabric, and a reduced problem of generation of a shear during washing, and a flexible polyurethane foam. The present invention relates to a cloth-attached flexible polyurethane foam product obtained by adhering a cloth to a cloth. Background of the Invention
- a flexible polyurethane foam has a good cushioning property, and has a long-lasting and soft feeling that it does not stick when used repeatedly like cotton. Widely used for clothing.
- a flexible polyurethane foam is used for clothing such as a brassiere pad or a shoulder pad
- the fabric is bonded to a molded article of the flexible polyurethane foam obtained by foam molding into a required shape, and hot-pressed. It is made into a cloth-applied product covered with fabric by one-piece
- the present invention provides a soft polyurethane foam product that can prevent the fabric from being squeezed by washing in a fabric-attached flexible polyurethane foam product bonded to a fabric and integrally formed by hot pressing as described above. With the goal.
- the flexible polyurethane foam of the present invention is obtained by foaming a polyurethane raw material containing 0.2 to 1.5 parts by weight of a low molecular weight crosslinking agent per 100 parts by weight of a high molecular weight polyol component having a molecular weight of 2,000 or more.
- the cloth-attached flexible polyurethane foam product of the present invention is characterized in that a cloth is attached to such a molded article of the flexible polyurethane foam of the present invention and hot-pressed.
- FIG. 1 is a cross-sectional view showing a mold press mold used in a hot press in Examples and Comparative Examples.
- the flexible polyurethane foam of the present invention is obtained by foaming a polyurethane raw material containing 0.2 to 1.5 parts by weight of a low molecular weight crosslinking agent per 100 parts by weight of a high molecular weight polyol component having a molecular weight of 2,000 or more.
- the present inventors have studied the causes of fabric shrinkage due to the washing of a cloth-attached flexible polyurethane foam product, and found that when washing is performed between the flexible polyurethane foam and the fabric, wetting and swelling and shrinkage during drying occur.
- the flexible polyurethane foam is locally swelled and shrunk due to the different ratios and the different swelling and shrinking ratios.
- this was the cause of bleeding into the fabric, and further investigation was conducted to reduce local swelling and shrinkage of the flexible polyurethane foam.
- the rare bond formed by the reaction between polyisocyanate and water during the urethane reaction is easily aggregated. ⁇ Aggregates of rare bonds referred to as rare balls are easily formed. Causes partial swelling and contraction of According to the present invention, the formation and aggregation of urea bonds due to the reaction between polyisocyanate and water due to the high reactivity between the polyisocyanate and the low molecular weight crosslinking agent by incorporating a predetermined amount of the low molecular weight crosslinking agent. By dispersing rare balls, the partial swelling and shrinkage of the flexible polyurethane foam is alleviated, and the entire foam absorbs the swelling and shrinking stress, so that it is bonded and integrated with this! / Prevents the penetration of cloth.
- a low molecular weight polyol having a molecular weight of about 100 to 200 and an OH value of about 400 to 2000 can be used as the low molecular weight crosslinking agent.
- low molecular weight polyols include trimethylolpropane, diethylene glycol, and PO adducts of trimethylolpropane (“T880” manufactured by Mitsui Takeda Co., Ltd.). These may be used alone. More than one species may be used in combination.
- the low molecular weight crosslinking agent is preferably used in an amount of 0.2 to 1.5 parts by weight, particularly preferably 0.4 to 1.3 parts by weight, based on 100 parts by weight of the high molecular weight polyol component.
- a general polyurethane raw material blend containing a high-molecular-weight polyol component, a polyisocyanate component, a foaming agent, a catalyst, and a foam stabilizer is used. It can be.
- the high molecular weight polyol component a polyester-based polyol and a polyester or polyester-based polyol having a molecular weight of 2,000 to 7000 and a valence of 20 to 90 can be used.
- One kind of high molecular weight polyol component may be used alone, or two or more kinds may be used in combination.
- the polyisocyanate to be reacted with such a polyol is not particularly limited, and is an organic polyisocyanate having two or more isocyanate groups in a molecule, and is an aliphatic or aromatic polyisocyanate.
- the isocyanate compounds and modified products thereof are also included.
- Examples of the aliphatic polyisocyanate include hexamethylene diisocyanate, isophorone diisocyanate, dicyclohexylmethane diisocyanate, methylcyclohexane diisocyanate, and the like.
- toluene diisocyanate, diphenyl methane diisocyanate, polymeric diphenyl methane diisocyanate and the like can be mentioned.
- modified products include carbodiimide-modified products and prepolymer-modified products.
- the preferred polyisocyanate is an aromatic polyisocyanate or a modified product of an aromatic polyisocyanate, and particularly preferably diphenylmethanediisomethane.
- cyanate, toluene diisocyanate, diphenylmethane diisocyanate and the like can be mentioned.
- any foaming agent used for producing a polyurethane foam can be used.
- low-boiling inert solvents such as fluorocarbon compounds such as trifluoromethane and dichlorodifluoromethane, methylene chloride; water, acid amides, nitroalkanes, and the like that generate gas by liquid carbon dioxide reaction; There are sodium bicarbonate, ammonium carbonate, etc. that generate gas.
- preferred foaming agents include methylene chloride, water and the like.
- catalysts used in the production of ordinary urethane foam can be used.
- examples thereof include tin-based catalysts such as dibutyltin dilaurate and stannasoctoate, and tertiary amines such as triethylamine and tetramethylhexamethylene diamine.
- the polyurethane foam of the present invention may further contain, if necessary, a surfactant as a foam stabilizer, a flame retardant, and other auxiliaries.
- a surfactant a silicone-based surfactant is usually used.
- the flame retardant include conventionally known flame retardants such as tris (2-chloroethyl) phosphate and tris (2,3-dibromopropyl) phosphate, organic powders such as urea and thiourea, and metal water. Inorganic powders such as acid oxide and antimony trioxide can be used.
- auxiliaries include coloring powders such as pigments and dyes, powders such as talc and graphite, short glass fibers, and other inorganic fillers and organic solvents.
- High molecular weight polyol component 100 parts by weight
