The present invention relates to heat sensitive adhesive interlining. The present invention also relates to its manufacturing method. In recent years, heat-sensitive adhesives have been used as interlining for clothing, etc., by dot-coating a non-aqueous paste-like heat-sensitive adhesive mixed with vinyl chloride resin and plasticizer on the surface of the base fabric, and scattering many granular adhesive dots. Gel interlining is becoming widely used. This interlining can be easily attached to the fabric by simply heat-pressing it with an iron or hot press, without sewing or other operations, and since adhesive dots are scattered on the surface of the interlining, This has the advantage that the flexibility of the fabric is maintained without the interlining being completely adhered to the entire surface of the fabric. However, the non-aqueous paste adhesive
When hot and press-bonded to the fabric, each adhesive dot has low fluidity, and there is little transfer to the fabric, which is the adherend.
Therefore, sufficient adhesive strength cannot be obtained, and if a large amount is applied to increase the adhesive strength, it has the disadvantage that the texture of the fabric is impaired. Furthermore, it also has the disadvantage that the resin oozes out onto the back surface of the interlining during heat-press bonding. While conducting various studies on heat-sensitive adhesive interlining, the present inventors discovered that the drawback of such heat-sensitive adhesive is that when it is coated in dots on an interlining base fabric, the plasticizer in each adhesive dot is absorbed into the core. Penetrates into the base fabric,
The ratio of plasticizer to vinyl chloride resin in the dots decreases, and the resin also permeates into the base fabric more easily as the plasticizer increases, causing the dots that are sufficiently raised from the base fabric surface to deform immediately after application. , I learned that it comes from being tired. However, this phenomenon cannot be avoided as long as a non-aqueous paste adhesive is used.On the other hand, conventional heat-sensitive adhesives for interlining using vinyl chloride resin and plasticizers
Generally, a non-aqueous paste is used. Therefore, the inventors of the present invention have conducted extensive research in order to eliminate the drawbacks of conventional heat-sensitive adhesives for interlining and to obtain a heat-sensitive adhesive interlining that exhibits sufficient adhesive strength.
We learned that the heat-sensitive adhesive for interlining can be made into an aqueous dispersion system, and discovered that an aqueous dispersion composition of a vinyl chloride resin and a plasticizer, which has a specific composition and physical properties, is suitable for that purpose. , we have completed the present invention. That is, the present invention provides vinyl chloride resin and 50 to 100 parts (parts by weight, same hereinafter) of the resin.
A water-dispersed heat-sensitive interlining adhesive with a viscosity of approximately 10,000 to 80,000 cps at 20°C, made by dispersing 150 parts of a plasticizer in water using an emulsifying thickener, is coated in dots on a base fabric. The present invention provides a heat-sensitive adhesive interlining and a method for producing the same. According to the present invention, since the heat-sensitive adhesive is a water-dispersed system, when it is coated in dots on the interlining base fabric, only water penetrates into the base fabric, and the hydrophobic plasticizer penetrates into the base fabric. The dots are held in the adhesive dots without causing a drop in the ratio of plasticizer to resin, and the dots maintain their shape sufficiently elevated from the surface of the base fabric almost immediately after application. Therefore, each adhesive dot exhibits good fluidity when hot and press-bonded to the fabric, sufficient adhesive strength is obtained, and it is also possible to prevent the resin from seeping out to the back surface of the interlining. Moreover, since conventional adhesives are non-aqueous, it is necessary to use solvents to clean each device after application, but according to the present invention,
It also has the advantage that such equipment can be easily cleaned using only water. Thus, the heat-sensitive adhesive for interlining used in the present invention is a water-dispersed, concentrated liquid or paste composition containing a vinyl chloride resin, a plasticizer, and an emulsifying thickener as essential components. The vinyl chloride resin used may be any commonly used resin, including polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, and has an average particle size of 10 to 10.
It is blended in the form of granules or powder of 300 mesh, preferably 30 to 250 mesh. As the plasticizer, phthalate ester plasticizers such as diisooctyl phthalate, dioctyl phthalate, benzyl butyl phthalate, dibutyl phthalate, dihexyl phthalate, and dicyclohexyl phthalate, singly or in mixtures thereof, are used to improve the fluidity of the adhesive dot, From the viewpoint of heat-sensitive adhesiveness, 50 parts of vinyl chloride resin is
~150 parts, preferably 80 to 120 parts. As the emulsifying thickener, for example, an acrylic acid polymer such as Carbopol, or an ethylene glycol emulsifying thickening agent such as polyethylene glycol higher fatty acid ester is used, and if desired, these may be combined with a thickening agent such as polyvinylpyrrolidone. May be used together. From the viewpoint of ease of application, these blending amounts are such that the viscosity of the resulting adhesive at 20°C is approximately 10,000 to 80,000 cps (B8H type viscometer, 20 rpm, rotor No. 7), preferably, It should be about 10,000 to 50,000 cps. For example, when using Carbopol,
It is desirable to use 0.1 to 1 part of Carbopol and 1 to 10 parts of a thickener such as polyvinylpyrrolidone in combination with 100 parts of resin.
It is desirable to mix 5 to 20 parts per 100 parts. The amount of water as a dispersion medium can be selected depending on the components actually mixed, the desired viscosity, etc., but in general,
50 to 300 parts per 100 parts of resin is sufficient; for example, 50 to 150 parts per 100 parts of resin when using an acrylic acid polymer as an emulsifying thickener, and 50 to 150 parts when using an ethylene glycol-based one. 150 to 300 parts is preferred. If desired, the heat-sensitive adhesive for interlining used in the present invention may further contain other components such as a viscosity modifier such as polyethylene oxide, a pigment, and a fluorescent dye. The heat-sensitive adhesive for interlining used in the present invention can be produced by dissolving an emulsifying thickener and, if desired, a thickening agent in water, and emulsifying and dispersing a plasticizer and a vinyl chloride resin therein. In particular, when using an acrylic acid polymer as an emulsifying thickener, an alkali is added to a W/O type dispersion obtained by adding and dispersing an emulsifying thickener, a thickener, and water to a plasticizer. It can also be produced by inverting the phase to an O/W dispersion by adding and dispersing a vinyl chloride resin. For example, when using an acrylic acid polymer as an emulsifying thickener, first, the emulsifying thickening agent and, if desired, the thickening agent are added to the plasticizer under stirring and sufficiently dispersed to obtain a liquid mixture. Next, most of the water to be blended (50 to 100 parts per 100 parts of resin) is added to this mixed solution and dispersed. When the water is sufficiently dispersed, stop stirring and defoamer. Separately, dissolve a predetermined amount of alkali such as sodium hydroxide in the remaining water and add this to the above mixture while stirring,
Adjust the pH of the liquid to 5-9. Before the addition of the alkali, the mixed solution is a W/O type system, but the phase is inverted to the O/W type by the addition of the alkali. In addition, while the pH has better phase stability on the alkaline side, there are problems with work hygiene when making it too alkaline.
It is preferable to adjust the pH to 7 to 7.5. Then,
A vinyl chloride resin is added to this phase-inverted O/W type mixed solution and dispersed to obtain a desired heat-sensitive adhesive for interlining. The heat-sensitive adhesive interlining of the present invention can be obtained by coating the surface of the base fabric in dots with the obtained water-dispersed heat-sensitive interlining adhesive. The interlining base fabric to be used is not particularly limited, and may be selected from natural fibers,
A variety of synthetic fibers such as woven, non-woven, and knitted fabrics can be used. Further, the size, pattern, etc. of the adhesive dots on the surface of the base fabric are not particularly limited. In the heat-sensitive adhesive interlining of the present invention, the adhesive is applied onto the surface of the base fabric using a rotary screen having a screen of 10 to 30 meshes in a predetermined amount, preferably 30 to 60 g/m 2 , in the form of dots. , then heated at 120-130℃ for 5-30 seconds,
It can be manufactured by drying and fixing adhesive dots on a base fabric. The obtained heat-sensitive adhesive interlining can be attached to fabric by heat-pressing with an iron or hot press in accordance with a conventional method, without damaging the texture of the fabric.
Sufficient adhesive strength can be obtained without problems such as resin leaking to the back surface of the interlining. Next, the present invention will be explained in more detail with reference to Examples. Example 1 Water-dispersed heat-sensitive adhesive formulation Ingredients Vinyl chloride-vinyl acetate copolymer (vinyl acetate approx.
10%) (approximately 270 mesh) 100 Plasticizer (1:1 mixture of diisooctyl phthalate and benzyl butyl phthalate) 100 Emulsifying thickener (Carbopol 934) 0.6 Thickener (30% polyvinylpyrrolidone aqueous solution)
19 Sodium hydroxide Adjust the pH to approximately 7.0 Water 70 According to this recipe, add the emulsifying thickener and thickener to the plasticizer while stirring with a dissolver and thoroughly disperse. While continuing to stir, add about 2/3 of the water to this mixture and thoroughly disperse it.
Then, stirring is stopped for several minutes to allow defoaming. Dissolve sodium hydroxide in the remaining water, add to the mixture obtained above while stirring, and adjust the pH to about 7.0. At this point, the mixed liquid changes from a W/O type system to an O/W type system.
Phase inversion to a system of types. The copolymer is added to the obtained mixed solution and stirred at low speed (500 rpm) to obtain a smooth paste-like water-dispersed heat-sensitive adhesive (viscosity 3
5,000 cps). The obtained adhesive is applied to the interlining base fabric (cotton plain weave, 40 count,
Using a rotary screen with a 20-mesh screen on top of the
g/m 2 and coat the adhesive in dots. It is then heated at 125° C. for 15 seconds to obtain the desired heat-sensitive adhesive interlining. The obtained interlining is heated using a flat plate press machine at a temperature of
15 on various fabrics under the conditions of 140℃ and 250g/ cm2 pressure.
The results of measuring the adhesive strength (by peel test method) when heated and pressed for seconds are shown in Table 1 below. As a control, the results of a similar test using an interlining obtained by applying a conventional non-aqueous paste heat-sensitive adhesive in the same amount to the same base fabric are also shown.
