• Polyvinyl acetate adhesives sometimes cause peel off at relatively high temperature in comparison with other adhesives.
• styrene-acrylonitrile-alkylacrylate terpolymer has been proposed as an aid in improving dyeing of acrylonitrite synthetic fibers, it has not been proposed as a thermoplastic adhesive for fusible interlinings.
• This invention relates to a fusible interlining containing as an adhesive terpolymeric resin characterized in that of the said terpolymer consists of 3-30% by weight of styrene, 20-50% by weight of acrylonitrile and 20- 77% by weight of alkylacrylate having C -C alkyl radical, said terpolymer having an intrinsic viscosity in the range of 0.3-0.7 (determined in dimethylformamide at 30 C.) and a melting point range of 60-150 C.
• Said terpolymeric resin is suitably employed on said interlining in powder, fibrous or film state, or is used as interlining by itself without any base sheet.
• the interlining can be in the form of a fabric or repellent paper.
• Terpolymer' of styrene-acrylonitrile-alkylacrylate is obtained by polymerizing styrene, acrylonitrile and alkylacrylate (i.e. methylacrylate, ethyl acrylate, propylacrylate or butyacrylate) according to the common polymerization processes such as emulsion, polymerization, suspension polymerization, solution polymerization, or the like.
• alkylacrylate i.e. methylacrylate, ethyl acrylate, propylacrylate or butyacrylate
• aqueous or ororganic suspensions of styrene, acrylonitrile, alkylacrylate, catalyst and, if necessary, polymerization regulator and emulsifier are charged in a reaction kettle equipped with stirrer, reflux condenser and thermometer, and are polymerized in nitrogen .gas at required temperature and for desired periods of time.
• the resulting terpolymer of styrene-acrylonitrile-alkylacrylate is separated by a salting out method or solvent precipitation method, washed by water, alcohol or petroleum benzine, and dried. Then, white or light-yellowish, solid terpolymer of styreneacrylonitrile-alkylacrylate is obtained.

• alkyl amines such as diethyl amine
• alkanol amines such as monoethanol amine
• chlorinated hydrocarbons such as carbon tetrachloride, trichloroethylene, etc.
• emulsifying agent well-known surfactants can be used, but especially it is desirable that an anionic agent such as lauryl sodium sulfide, or non-ionic agent such as polyethylene glycol alkylphenol ether, be applied singly or jointly. Furthermore, these agents, when used in quantities, exert effective actions not only on emulsification but also on polymerization regulation so they are most suitable for making terpolymers employed pursuant to this invention.
• acrylamides and their derivatives vinyl acetate, methacrylonitrile, vinyl toluene, divinyl benzene, acrylic acid, glycyzyl methacrylate, alkyl methacrylate, other alkyl acrylates, etc. are employed as co-monomers that can be polymerized with styrene, acrylonitrile and alkylacrylate.
• One or more of the above-mentioned co-polymers can be polymerized subsidiarily in some cases.
• All that need be conducted for obtaining styrene-acrylonitrile-alkylacrylate terpolymer as in the invention is to select well-known conditions for polymerization reaction such as respective concentrations of said three monomers, methods of addition, kinds and amounts of catalyst, solvent, polymerizing regulator, emulsifying agent, etc. stirring speed at reaction, temperature, and so on.
• terpolymers of styrene-acrylonitrile-alkylacrylate which consist of 3-30% by weight styrene, 2050% by weight acrylonitrile and 2077% by weight alkylacrylate having C -C alkyl radical, and have intrinsic viscosity in the range between 0.3 and 0.7 (determined in dimethylformamide at 30 C.) and melt in the range of 60-150 C. can be obtained.
• These terpolymers fulfill all the following conditions requisite to thermoplastic adhesive for fusible interlining.
• thermosetting resins They do not have a limited shelf life as in thermosetting resins.
• composition percentages of styrene, acrylonitrile, and alkylacrylate in said terpolymers of this invention fall within the limits of 330% by weight of styrene, -50% by weight of acrylonitrile and 20- 77% by weight of alkylacrylate. These ranges are set forth because if the styrene content is below 3% by weight, the resulting terpolymer is inferior in resistance to water and alkali, and an interlining with said terpolymeric adhesive suffers from a disadvantage in resistance for washing. If the styrene content is over by weight, the terpolymers are not resistant to solvents and this means that interlinings with such terpolymeric resin suffer from a disadvantage in resistance during drycleaning.
• the intrinsic viscosity of styrene-acrylonitrile-alkylacrylate terpolymers in this invention is 0.3-0.7 (dl./ g.) in dimethylformamide at 30 C.
• terpolymers whose intrinsic viscosity is below 0.3 are applied as thermoplastic adhesives, the interlinings are poor in bonding strength and sometimes may cause fabrics to spoil or impair the touch of the fabric itself since these terpolymers are apt to strike into the fabrics during bonding, due to their own low intrinsic viscosity.
• the resultant interlining is insufiicient in bonding strength as well, since the terpolymer does not strike into fabric at all, due to its high intrinsic viscosity. If one attempts to bond the interlining to a fabric, the fabric to be bonded may be damaged or deteriorated.
• the melting temperature of styrene-acrylonitrile-alkylacrylate terpolymers employed pursuant to the invention are in the range of 60150 C. and the melting temperature of said terpolymers, necessitated for bonding the interlinings carrying said terpolymers as fusible agent, is C. at the highest. In case the melting temperature is over 150 C., the terpolymers are not suitable for interlining, since they must be given such severe conditions for bonding as may damage or deteriorate fabrics.
• melt temperature described here, rneans the temperature, at which polymers become soft by heating and their viscosity begins to drop rapidly. Generally, it is determined by the temperature, at which polymers become soft by heating under constant pressure and then begin to How. More, melting temperature can be also determined by the temperature, at which polymers begin to melt, using a constant pressure extruding flow tester, e.g. KOKA Flow Tester (a tester, developed by Kobunshi Kagaku Kenkyusho and made by Shimazu Seisakusho), that is, by the temperature at which the plunger starts to drop by the flow of melted polymers into the nozzle.

• Said terpolymers are used as thermoplastic adhesives in states of powder, fiber or film.
• Fusible interlinnigs of this invention provide excellent bonded products having eminent bonding strength without impairiing the touch of fabric to be bonded.
• Bonded products of interlinings in this invention and fabrics have excellent resistances for washing and drycleaning, needless to say durability as garments.
• Interlinings of this invention facilitate the temperature control of pressing machines, since they can be bonded in wide range of pressing temperature (e.g. 100- 180 C.) and more the bonded products have excellent bonding strength.
• Styrene-acrylonitrile-alkylacrylate terpolymers applied as heat-sensitive adhesives of this invention, can provide interlinings fusible at fairly low temperature, since their bonding strength and resistances are excellent even if the terpolymers melting at relatively low temperatures such as 60100 C. are employed as fusible agent for interlinings.
• Heat-sensitive adhesives comprising the terpolymers possess suitable properties for processings, so that various kinds of interlinings can be provided in accordance with this invention.
• Styrene-acrylonitrile-alkylacrylate, terpolymers, applied as heat-sensitive adhesives of this invention are effective for interlinings even if plasticizer is not used jointly, so there is no fear of causing deterioration at storage or use, resulting from the transition of plasticizer.
• Styrene-acrylonitrile-alkylacrylate terpolymers applied as heat-sensitive adhesives of this invention, do not have limited shelf life (storage life), since they are thermoplastic resins. Accordingly, interlining carrying said terpolymers as fusible agent possess excellent stabilization at storage.
• Styrene-acrylonitrile-alkylacrylate terpolymers applied as heat-sensitive adhesives of this invention, are excellent in stability to heat, so interlinings comprising 'said terpolymers do not bring about coloring or decomposition during bonding to fabrics. Accordingly, there is no fear of spoiling or damaging fabrics.
• Fusible interlinings of this invention make it possible to improve manufacturing processes of garments by bonding the same with pre-cut outer fabrics or linings instead of stitching the same together. That is, they contribute greatly to labor-savings of hand-working processes, without lowering the quality of finished garments.
• Fusible interlinings of this invention show eminent bonding strength and more have excellent resistances even if they are bonded at low temperature in the event steaming is conducted during bonding with fabric. Therefore, they are especially useful for bonding with fabrics susceptible to heat-discoloring or heat-shrinkage.
• the amount of fusible interlining disposed on the surface of the woven or nonwoven fabric will depend upon the nature of such fabric, its weight and the particular use for which the interlining is to be employed. Various sections of a garment may require different amounts of adhesive on the interlining to provide the desired stiffening or supporting function. Generally speaking, there will be between 15 and 45 grams of terpolymer per square meter of interlining fabric.
