Section 1, Public Law 690, August 8, 1946 Patent expires January '25, 1963 7 Claims. (Cl. 154-118) This invention relates to means and a method for marking articles.
It is common practice to identify articles which are to be laundered by printing identification marks upon each article in an inconspicuous place with permanent black ink. Another method is to employ identification tabs, some ofwhich are made of cloth and sewn to the article, whilst others are made of metal and clamped or stapled to the article. Still another method is to sew identification figures or letters directly into the article. I
None of these methods works satisfactorily, and the question of laundry marking has been a constant source of trouble for commercial laundries. The permanent black identification marks are very objectionable because they disfigure the laundry article, and the same applies to the sewn-on tabs and the sewn-in identification marks, as they cannot be removed. In the case of metal tabs, which can be removed by the laundry, these tabs often become caught or entangled, and torn from the article in the course of the washing, and they also wear out the article. Furthermore, in the case. of permanent black identification marks and sewn-on tabs orsewnin identification marks, it takes the operator a considerable time to find an inconspicuous place for placing the mark and, when thelaundering process has been finished, it takes him still more time to locate these marks or tabs, which must be comparatively small in order to confine the disfigurement of the article to a minimum. These are drawbacks and difficulties which arise when an article is sent to a laundry and laundered even for the firsttime. They are, obviously, multiplied if the article has gone through a different laundry, or several laundries, before, and bears more than one identification mark.
.It has also been proposed in United Kingdom specification No. 78,699 to provide a label adapted to adhere to an article upon being'applied to said article with heat and pressure, said label comprising a front face bearing or constituting a legend or device and a back face of fabric having yarns or filaments of a thermoplastic derivative of cellulose exposed thereon.
It is stated that the label may be applied to a shirt or like article to which it is substantially permanently welded or from whichit can be separated only with difilculty.
t is an object of the present invention to prov'id means" for marking articles which are to be laundered'whilst overcoming the aforesaid disadvantagesazid difficultisl It is a further object of the invention to provide means for marking articles for other purposes e. g. for indicating the price thereof.
It is a still further object of the invention to provide an improved method of marking textile articles. H
With these objects in view the present invention provides a tab for marking articles which contains or consists of or presents on a substantial area of one side thereof a thermoplastic material which is not softened at C., but which is softened at a temperature well below the scorching point of textile material to which it may be attached by heat and pressure and which is easilyaffected by heat, for example, artificial silk, and has on the face thereof numerals, and which is easily removable by tearing ofi without aifecting the material to which it is attached.
In one application of the invention a finely woven fabric, such as cotton, serving as a backing, is coated on one side with the thermoplastic material. It will be understood that more than one coating may be applied to the backing, if desired. When th tab is to be used in marking articles in the manner disclosed and claimed herein the coating will be applied to a portion only of one side of the fabric and the coated fabric is cut into tabs or strips so as to leave a part of the coated side free from the thermoplastic material.
The side of the tab notcoated with the thermo, plastic material is used for marking with numerals, with or without letters or other indicia.
forthe purpose of identifying the article to which the tab is to be attached or for indicating the price of, the article.
According to another form the tab may consist of a fabric formed at least in part of filaments or yarn of a thermoplastic material.
The side of the tab which is not to be attached to the article is used for marking with numerals,
with or without letters or other indicia for the 3 that is left substantially free from the thermoplastic material in order to facilitate removal. The tab is applied to the article by heat and pressure, with or without the use of solvents or plasticizing qr softening agents.
According to the method ofmarking claimed herein, tabs prepared in one of the described Ways or in an equivalent manner and containing, con; sisting or presenting thermoplastic material of the described characteristics on a portion only of the reverse side thereof are first printed with the desired identification or other; markingindicia on the face side, then positioned on the garment or other textile article to be marked thereby and thereafter bonded to the article by application of heat and pressure to the exposed face of the tab to thereby cause. this talg along the portion of the reverse side thereof hearing. or presenting the thermoplastic material to be.- come adhered to the article While leaving the remainder free to serve as a finger piece for eventual tearing off ofthe, tab. In applying the tab the heat is regulated to such a degree, hav ing regard to the softening properties of the thermoplastic contained in the tab o'rpresented at the reverse side thereof and also having regard to the scorching properties of the textile material of; the article being'marked, as to cause the thermoplastic material to be softened and adhesive while at-the same time keeping the temperature low enough to avoid scorchingor other untoward action on the textile material of which the article is constituted.
Conveniently and; in a preferred form of the method, a suitable material in the form of a sheet, strip or tape and presenting on a portion only of' one side thereof a thermoplastic material which is not softened at 100- C; but'is softenable and capa'ble'of being rendered adhesive by heat and pressure at temperatures Within the range above defined, is cut into smaller strips or pieces of suitable size for a marking t'a'b orlabel and thenQas individual tabs are requiredfor marking articles, each tab is successively printed with suitable indicia on one face thereof, positioned on the article tobe' marked thereby and: thereafterbonded tothe article'over a portion onlyof;
the reverseside oi -the tab by applying heatand pressure to the faceof the tab, leavinga finger piece for tearing-offpurposes;
If desired, thetabs-maybe preparedin such manner as to provide thermoplasticinater-ia-l overthewhole of the-surface, in which'casein applying-the tabs in the m'arldng operation care shouldbe taken to see that heatand' pressure are applied to a portion onlyof" the fac of; the tab leavingone-edge portion free toserve as a finger piece in removing the tab when-it-has ser-veditS purpose. This method'of marking isclaimed in myicopendingdivisional application Serial No. 320,622 filed Novem'berle, 1952.
Owing. to the comparatively high softening range of the .thermoplasticmaterial the bond between-the tab and-the article willnct-be affected by the temperature at which the laundering is carried out. Furthermore, the bond willbe such as not-to be affected-bythe-mechanicalstrain of: the washing, bleaching,- sOur-ing, extracting, hot-drying and ironing. Before the final distributioniofgthe marked-articles to customers the tab canconveniently be removedby tearing itofi; The following examplesfurther illustrat how the invention may becarried into effect:
1. A finely woven cotton material is coated witha-solution consisting ofl9parts by-weightpf a co-polymer of vinyl acetate and vinyl chloride, 10 parts by weight of amyl tartrate, 5 parts by Weight of tricresyl phosphate and 66 parts by weight of acetone, with the aid of a coating machine. The material is dried, cut into tabs of a suitable size and the tabs are printed with numerals, with or Without letters or other suitable identification marks. Part of the cotton material, hOWEVQr, is left uncoated, and the tabs cut so as to leave part of them free from the thermoplastic material. On the application of heat and pressure, this part of the tab will not adhere to the article, to be laundered, and this will greatly facilitate the removal of the tab after the laundering process.
2. A fabric in which are employed mixed yarns containing approximately 40% of filaments of cellulose acetate (in the manufacture of which hasbeen incorporated a water-insoluble plasticizing agent such as diethyl or dimethyl phthalate) and approximately 60% of fibres of cotton, is out into tabs of a suitable size and the tabs are printed with numerals, with orwithout letters or other suitable identification marks. on the application of heat and pressure to only part of thetab, this part will adhere firmly to the article to be laundered, whereas the other part will not adhere, thus facilitating the removal of the tab f-ter the laundering process; If it is desired to assist the melting orsoftening of the cellulose acetate, a volatile solvent for the celluloseacet-a'te, and a plasticiser, can be present duringth'e application of heat and pressure, a suitable mix:- ture being 92% of acetone and 8% of 'di-ethyl phthalate.
