Description

  The present invention relates to a glove insert comprising a plant-derived component. More specifically, it is used as an intermediate layer between the outer shell (outer surface) and inner (lining) of the glove, or as an inner layer, especially for skiing, mountain climbing, riding, hunting, etc., and the environmental impact in recent global warming countermeasures It is related with the glove insert containing the plant-derived component which contributes to carbon neutral for the reduction | decrease.

  As a fabric made of a plant-derived component, for example, a fabric using a polylactic acid resin is known (for example, Patent Document 1).

  However, in glove inserts and inners used for general sports, particularly skiing, mountain climbing, riding and hunting, no attempt has been made to reduce the environmental burden by incorporating plant-derived components.

In light of the above, the present inventors have attempted to develop a glove insert using a plant-derived component, but it is difficult to impart a water pressure equivalent to that when using a petroleum-derived raw material alone with a plant-derived component. there were. There has also been a demand for imparting excellent moisture permeability to the glove insert in order to further improve the comfort when wearing gloves.
JP-A-2005-307404

  The present invention has been made in view of the above, and is a glove insert used as an intermediate layer between an outer shell (outer surface) and an inner (lining) or as an inner, and can reduce the environmental load due to carbon neutral. It is another object of the present invention to provide a glove insert containing a derived component and having excellent waterproofness and moisture permeability.

  As a result of intensive studies, the present inventor can realize carbon neutral for reducing environmental load by using a polyurethane resin film containing 10 to 80% (% by weight, the same applies hereinafter) of plant-derived components, particularly polyurethane. By synthesizing mainly a castor oil-based polyol as a polyol component of the resin, it was found that a waterproof layer having performance equivalent to that of a polyurethane resin film made of petroleum-based polyol can be obtained, and the present invention has been completed.

  That is, in the glove insert of the present invention, the upper part and the palm part are each composed of a laminated body of a moisture permeable waterproof membrane and a fabric, and are bonded to each other at the peripheral part of the surface on the fabric side by an adhesive so as to be almost finger-shaped. The moisture permeable waterproof membrane is made of a polyurethane resin membrane containing 10 to 80% by weight of plant-derived components.

  As the polyol component constituting the polyurethane resin, castor oil diol can be suitably used.

  The castor oil diol is a castor oil-based polyether polyester diol having an average number of hydroxyl groups of 1.8 to 2.1 and a hydroxyl value of 41 to 85 mgKOH / g.

The polyurethane resin film containing 10 to 80% by weight of the plant-derived component is a porous film formed by a wet film forming technique, and the water pressure resistance of the fabric laminated with the moisture-permeable waterproof film is 10 kPa or more, Is 2,000 g / m ² · 24H or more according to JIS 1099 A-1.

The polyurethane resin film containing 10 to 80% by weight of the plant-derived component is a nonporous film formed by a dry film molding technique, and the water pressure resistance of the fabric laminated with a moisture permeable waterproof film is 10 kPa or more, The moisture permeability may be 2,000 g / m ² · 24H or more according to JIS 1099 B-1.

  The content of the plant-derived component is more preferably 25 to 65% by weight.

  It is preferable that the width | variety of the adhesion part by which the said upper part and the palm part were bonded together by the adhesive agent is 1-5 mm.

  It is preferable that the bonded portion where the upper portion and the palm portion are bonded has a water pressure resistance of 10 kPa or more.

  The fabric preferably has an elongation of 100% or more in either length or width.

  According to the present invention, by containing a predetermined amount of plant-derived components, carbon neutral for reducing environmental impact can be realized, and waterproofness and permeability equivalent to those when using a polyurethane resin film made of petroleum-based polyol are used. It becomes possible to provide a highly comfortable glove insert having moisture.

  Hereinafter, details of the glove insert of the present invention will be described.

  The polyurethane resin film used in the present invention is synthesized mainly with plant-derived components in order to be biodegradable, and the plant-derived components are more preferable from the viewpoint of reducing environmental burden, but are practical. In order to obtain a polyurethane resin, the lower limit is 10% and the upper limit is 80%. Considering the balance between environmental load reduction and the performance of the polyurethane resin, 25 to 65% is preferable.

  In particular, castor oil diol is mainly used as a polyol component of a polyurethane resin, and a porous moisture-permeable film is obtained by wet-forming a polyurethane resin, and a glove having moisture permeability is obtained by using this as a waterproof layer. An insert is obtained.

Carbon dioxide absorption per kg of castor oil, which is a raw material of castor oil-based polyol, was 16 kg (94th Lecture Meeting of the Tropical Agriculture Society of Japan “Effect of Cultivation Density on Dry Matter Production and Distribution, and CO ₂ "Absorption amount and solar energy utilization efficiency" (September 2003)), and is highly useful in terms of carbon neutrality. Incidentally, the carbon dioxide absorption of carbon neutral neutral polylactic acid is 1.83 kg (as carbon dioxide emission = carbon dioxide absorption), and the carbon dioxide absorption of kefna is 1.5 kg. The oil absorption is much greater.

Castor oil is a triglyceride of ricinoleic acid represented mainly by the following formula.

In addition, ricinoleic acid is a compound having a structure represented by the following formula.

  The castor oil diol as referred to in the present invention is a diol derived from castor oil, among which castor oil-based polyether polyester diol has an average number of hydroxyl groups of 1.8 to 2.1, and a hydroxyl value of 41 to 41. Those having 85 mg KOH / g are preferred, and those having an average number of hydroxyl groups of 1.95 to 2.05 can be suitably used. When the number of hydroxyl groups exceeds 2.1, it is difficult to obtain a polyurethane resin suitable for coating for forming a resin film because of the generation of a trivalent polyol branch or crosslinked structure. That is, it is preferable that the urethane resin used in the present invention has a linear structure, has little branching or cross-linking structure, and has a solution viscosity that can be coated on a fabric. Increasing the branch structure increases the viscosity and makes it unsuitable for coating. Moreover, when it becomes a crosslinked structure, the viscosity change occurs even in a very small amount, the viscosity change is large even in a small amount, and if the amount of crosslinking further increases, a urethane resin solution cannot be obtained.

  Examples of a method for obtaining a polyurethane resin containing plant-derived components include polar solvents such as dimethylformamide (DMF) and dimethyl sulfoxide (DMSO), and solvents such as methyl ethyl ketone (MEK), toluene, and xylene. In addition, a divalent plant-derived polyol such as castor oil diol is dissolved, and divalent isocyanate (hexamethylene diisocyanate, isophorone diisocyanate, diphenylmethane diisocyanate (MDI), hydrogenated MDI, etc.) is added thereto and allowed to react sufficiently. After preparing a prepolymer having an isocyanate or a hydroxyl group at the terminal, a diol (petroleum-derived ethylene glycol, propylene glycol, butylene glycol, etc., plant-derived 1,3-propanediol, 1,2-hexanediol, Etc.), or a divalent isocyanate was added (hexamethylene diisocyanate, isophorone diisocyanate, diphenylmethane diisocyanate (MDI), and hydrogenated MDI), it is possible to use a method of increasing the polymerization degree of a chain extending reaction.

  In the above, when a prepolymer is formed by reacting a divalent plant-derived polyol and a divalent isocyanate, if necessary, in addition to the divalent plant-derived polyol, other polyols such as polyesters are used. It is also possible to copolymerize polyols and polyether polyols. More specifically, divalent petroleum-derived polyols such as polyethylene adipate, polybutylene adipate, polycaprolactone diol, polyethylene glycol, polypropylene glycol, and polytetramethylene glycol can be copolymerized. Alternatively, polycarbonate polyol, silicone polyol, fluorine polyol, polyamide polyol and the like can be copolymerized and used. Polyols other than these plant-derived polyols can be mixed in a proportion of 50% by weight (solid content ratio) or less in the total amount of polyol, but the mixing amount is 25% by weight (solid content ratio) in order not to reduce the plant-derived ratio. The following is desirable.

  However, the method for polymerizing a polyurethane resin containing a plant-derived component is not particularly limited to these methods.

  In order to obtain a waterproof layer having moisture permeability, for example, a method of obtaining a microporous membrane from a polyurethane resin containing a plant-derived component by a wet membrane molding technique (hereinafter referred to as a wet method) is used. Moreover, when polymerizing the polyurethane resin containing a plant-derived component, a nonporous film having moisture permeability can be obtained by a dry method by copolymerizing a polyol made of polyethylene glycol.

  More specifically, a polyurethane resin solution obtained by dissolving a polyurethane resin containing a plant-derived component in a water-soluble polar solvent (DMF, DMSO, etc.) is coated on a release cloth, etc. A microporous membrane having both moisture permeability and waterproofness can be formed by wet gelation in an aqueous solution containing a polar solvent.

  Alternatively, when a polyurethane resin containing a plant-derived component is synthesized, an oxyethylene group-containing polymer diol is copolymerized to form a moisture-permeable polyurethane resin, and a polyurethane resin solution obtained by dissolving the polyurethane resin solution in a solvent that dissolves the polyurethane resin solution is separated. There is a method of forming a non-porous film having both moisture permeability and waterproof properties by coating on a pattern paper or the like and drying this solvent.

  In order to impart moisture permeability to the polyurethane resin, in addition to the oxyethylene group-containing polymer diol, for example, polyethylene glycol (hereinafter abbreviated as PEG), polyoxyethylene oxypropylene block or random copolymer as a divalent polyol. Diol, polyoxyethyleneoxytetramethylene block or random copolymer diol; ethylene glycol, propylene glycol, 1,4-butanediol, 1,6-hexamethylene glycol, bis (hydroxymethyl) cyclohexane, 4,4′-bis ( Ethylene oxide adducts of low molecular weight glycols such as 2-hydroxyethoxy) -diphenylpropane; PEG with a molecular weight of 1000 or less and dicarboxylic acids (eg succinic acid, adipic acid, sebacic acid, terephthalic acid, iso Condensation polyetherester diols obtained by reacting the like Tal acid), or may also be used a mixture of two or more thereof.

  The polymerization of the polyurethane resin containing a plant-derived component is not particularly limited to these methods.

  If necessary, additives such as silica fine powder, water repellent, pigment, matting agent, function-imparting agent (deodorant, antibacterial agent, etc.) can also be added to the polyurethane resin.

  As a method for producing a fabric laminated with a moisture permeable waterproof membrane of a polyurethane membrane containing a plant-derived component of the present invention, a resin solution may be directly coated on the fabric, or a release cloth, a release paper may be coated, etc. The formed moisture permeable waterproof membrane can be laminated on the fabric using an adhesive, but is not limited thereto.

  As a coating method, various coating methods such as knife coating, knife over roll coating, and reverse roll coating can be appropriately used.

  The moisture-permeable waterproof membrane preferably has a water pressure resistance of 10 kPa or more from the viewpoint of practical waterproof performance.

Further, the moisture-permeable waterproof layer is moisture permeability as in Method A-1 2,000g ^/ m 2 · 24hrs or more, or, it is desirable to have a more 2,000g ^/ m 2 · 24hrs at B-1 method.

  Lamination to the fabric can be performed by whole surface adhesion with a moisture-permeable adhesive, or dot adhesion by gravure coating or the like regardless of the presence or absence of moisture permeability.

  Examples of the adhesive that bonds the fabric surface of the back and palm of the glove insert to each other include a two-component curable adhesive, a hot-melt adhesive, and the like. It is preferable to use a melt-type adhesive, and examples of the material include polyurethane and acrylic. From the viewpoint of good texture, it is preferable to use polyurethane. When performing hot pressing, if the temperature is too high, the fabric and the moisture-permeable waterproof membrane are damaged, which is not preferable. Therefore, the melting point of the polyurethane having hot melt property used as an adhesive is 70 to 150 ° C. Preferably, it is 80-120 degreeC.

  Also, when the fabric surface and fabric surface of the back and palm of the glove insert are bonded together with an adhesive coated in a hand shape, the adhesive strength is weak if the adhesive width is narrow, when sewing gloves and wearing gloves This is not preferable because the insert is damaged. Also, if the adhesive width is too wide, the adhesive part hits the finger when wearing the finished glove product and the glove insert, and the feeling of wearing becomes unpleasant, which is not preferable. From these things, it is preferable that the width | variety of the adhesive agent applied to the hand shape is 1-5 mm, More preferably, you may be 2-4 mm.

  If the glove insert has a low water pressure at the bonding part of the upper part and the palm part, it is preferable because the water penetrates into the glove when it gets wet when it is wet. Absent. From this, it is preferable that the water pressure resistance of the bonded portion of the upper part and the palm part is 10 kPa or more, and more preferably, the water pressure resistance is 30 kPa or more in order to improve waterproofness.

  The fabric of the upper part and palm part of the glove insert is preferably a warp knitting or a circular knitting having a high degree of elongation from the viewpoint of care and fit, and either the warp or the width has an elongation of 100% or more. It is preferable to have. However, it is not limited to a knitted fabric as long as the elongation is high.

  The material of the fabric is not particularly limited, but, for example, a knitted fabric with high elongation using a processed yarn of nylon or polyester can be suitably used.
