Definitions

  • the present invention relates to a method for imparting pressure sensitive adhesion to velvet type fasteners. More particularly, it relates to a method for imparting pressure sensitive adhesion to the respective back surfaces of the male and female pieces of velvet type fasteners.
  • velvet type fastener or fastener used herein refers to the above-mentioned two kinds of fasteners.
  • the male and female pieces have been secured on woven and knitted fabrics by sewing.
  • it has been difficult to carry out such a sewing operation owing to the presence of the engagingelements of the 'male and female pieces and, in addition, the engaging elements of these pieces have many times been partly sewn in by the sewing thread.
  • the inevitable consequences of these problems have been lower securing efficiency and poorer fastening effect.
  • For thick or stiff materials such as carpet, natural or synthetic wood and shaped resinous articles, it has been very difficult or impossible to effect the above-mentioned sewing operation.
  • the principal object of the present invention is to provide a method for imparting pressure sensitive adhesion which enables a velvet type fastener to be secured easily and quickly to the material on which the fastener is used said fastener and possessing excellent adhesive strength and creep resistance in practical use.
  • the object of the present invention can be accomplished by applying an adhesive composition of the nature disclosed hereinafter to the velvet type fastener.
  • the method according to the present invention is a novel method for imparting pressure sensitive adhesion to velvet type fasteners, comprising applying to the re spective back surfaces of the male and female pieces of composition consisting of: parts by weight of a polymer, containing at least 65 percent mol of an ester of acrylic acid or methacrylic acid and from 0.2 to '5 parts by weight of a glycidyl ester of an unsaturated organic acid; from 0.5 to 5 parts by weight of a zirconyl salt of organic acid, and; from 0.01 to 0.1 part by weight of a volatile acid addition salt of an organic amine.
  • the method of the present invention can suitably impart superior and stable adhesive strength and creep resistance to the velvet type fastener.
  • the velvet type fastener to which the adhesive composition according to the present invention has been applied can be secured easily and quickly to the desired materials.
  • the velvet type fasteners composed of synthetic fi bers and usable for the method ofthe present invention include fasteners composed of the fibers such as polyamides, polyesters and polyolefins.
  • fasteners composed of the fibers such as polyamides, polyesters and polyolefins.
  • woven or knitted multifilament yarn fabrics of polyamides or polyesters may be suitably used for the loop elements and the base fabric of the.
  • female piece and woven or knitted fabrics of densified polyethylene, polypropylene or polyvinyl chloride as well as fabrics of polyamides or polyesters maybe suitably used for the base fabric of the male piece, because of their desirable properties such as tensile strength and elasticity.
  • a monofilament yarn of polyamides, polypropylene polyethylene, polyoxymethylene or the like may be suitably used in view of the necessity of excellent elasticity and rigidity.
  • the polyamides are preferably utilized for the loop elements of the female piece and the base fabrics of the male and female pieces and also polypropylene is preferably utilized for the engaging male elements of the male piece.
  • the ester of the acrylic acid or methacrylic acid usable for the adhesive composition according to the present invention includes acrylic and methacrylic esters having at least two carbon atoms in the alkyl moimonomer such as vinyl acetate, methyl methacrylate and styrene may be used.
  • the copolymers may optionally comprise unsaturated acids such as acrylic acid, methacrylic acid, crotonic acid and itaconic acid.
  • the acrylic or methacrylic ester mainly participate in the pressure sensitive adhesion. When the ester is present in an amount of less than 65 percent mol in the polymer, the pressure sensitive adhesion of the fastener with the adhesive composition applied is undesirably reduced.
  • the monomers copolymerized with the above ester participate in yielding hard polymers. The monomers serve to control the tacking, improve the cohesive adhesion and also to elevate the creep resistance, of the adhesive composition.
  • the glycidyl ester of unsaturated organic acid which is a component of and usable for the polymer in the pressure sensitive adhesive composition may be the glycidyl esters of acids such as acrylic acid, methacrylic acid and crotonic acid. These glycidyl esters impart creep resistance and thermal stability to the adhesive composition and are suitably used in an amount of from 0.2 to 5 parts based on the weight of 100 parts of the polymer.
  • the glycidyl esters also react with a zirconyl compound as described hereinafter.
  • the glycidyl esters are used in an amount of less than 0.2 parts, it is difficult to obtain appropriate cohesive adhesion and creep resistance, while when the glycidyl esters are used in an amount of more than. 5 parts, the stability of the composition and the durability of the pressure sensitivity are reduced, more or less depending on the amount of the added zirconyl compound.
  • the most important features of the method of the present invention are that a specific amount of the zirconyl salt of an organic acid is added in the composition, and that the volatile acid addition salt of the organic amine is also used as an accelerator for the reaction of the zirconyl compound with the polymer.
  • the resinous composition comprising the polymer containing mainly the acrylic or methacrylic ester and partly the glycidyl ester of unsaturated organic acid, but not comprising the above-mentioned zirconyl compound and amine compound, is known as a reactive acrylic resin.
  • These known types 'of resinous compositions are generally utilized in the flocking of textile articles.
  • these known compositions cannot be utilized for the purpose of the present invention, because they are inferior in adhesion to the fastener, in durability of the adhesion and also in creep resistance.
  • the zirconyl salts of the organic acid usable for the present invention include, for example, zirconyl acetate, zirconyl p'ropionate, zirconyl caprate and zirconyl stearate. Particularly, zirconyl salts of higher fatty acids are preferably used.
  • the suitable amount of the zirconyl salts is from 0.5 to 5 parts based on the weight of 100 parts of the polymer, while they are preferably used in a range between 70 and 120 percent, based on the weight of the glycidyl ester of unsaturated organic acid.

  • the zirconyl compounds when used in an amount of more than 5 parts, based on the weight of parts of the polymer, durability of pressure sensitivity of the composition becomes inferior and the obtained fastener feels unpreferably hard.
  • the use of the zirconyl compounds in an amount of more than percent based on the weight of the glycidyl ester does not, to a large extent, increase the. effects for adhesion or creep resistance and, therefore, is uneconomical.
  • the adhesive composition used in the present method is stable under acidic conditions and that the composition is in the acidic pH range owing to the presence of the acid addition salt of the organic amine.
  • the composition is very stable at a pH below 6, preferably at a pH below 5.
  • the volatile acid addition salts of the organic amines include, for example, the salts of mono-, dior triethanolamine or mono-, dior tripropanolamine with acids, readily and relatively volatilized by heat, such as hydrochloric acid and acetic acid.
  • These acid addition salts exhibit acidic properties and can control the cohesive adhesion and the durability of adhesion of the resultant composition as mentioned above. Therefore, the composition containing the acid addition salts is slowly reacted while volatilizing the acid after being coated onto the fastener and produces excellent adhesion and creep resistance. When the composition is heated after being coated, it rapidly volatilizes the acid and also produces the above-mentioned effects.
  • the composition according to this invention may optionally comprise a small amount of hydrochloric acid, acetic acid or the like.
  • the acid, addition salts of organic amine are suitably used in an amount of from 0.0] to 0.1 part based on the weight of 100 parts of the polymer.
  • the amount of the acid addition salts is less than 0.01 part, the increasing of the cohesive adhesion of the composition cannot be obtained; while when the amount of the acid addition salts is more than 0.1 part, the pressure sensitivity of the adhesion is lost and the stability during. storage becomes slightly inferior.
  • the adhesive compositions usable for the method of the present invention may be prepared as follows.
  • the polymer is firstly prepared by known emulsion polymerization or solution polymerization procedures.
