Definitions

• the invention also includes a method of stiffening the loops.
• the present invention is directed to a novel looped pile fabric which is characterized in that the loops are stiffened over at least part of the surface of the fabric.
• the invention is also directed to the different articles which can be manufactured with the novel fabric, especially articles used for rubbing purposes, such as towels, face cloths and gloves, dish-cloths and floor-cloths, carpets, conveyor-belts or other similar articles which can be employed to exert friction or withstand repeated rubbing during use.
• the invention also comprises a method for the manufacture of fabrics and articles having stiffened terry loops.
• Terry loop fabrics are well known and are suited to a number of different uses; generally speaking, soft and supple terry loops are not intended either to withstand more or less energetic rubbing or to exert friction.
• the present invention provides an unexpected and highly useful technical improvement as a result of the creation of a new kind of looped pile fabric in which the terry loops have a degree of hardness which permits the utilization of the fabric for a number of different purposes in which more or less high rubbing friction is required.
• the invention has the additional advantage of per mitting the ready and economic conversion of a looped fabric of known type to a fabric having stiffened loops.
• the method according to the invention makes this conversion possible both on the fabric itself and on articles which have already been made such as, for example, bath towels, face-cloths, gloves, rugs and carpets, and so forth; the method can also be applied to the entire surface of the fabric or article, or alternatively to only one portion or selected portions of this surface.
• the novel fabric can have stiffened loops on only one face or on both faces.
• the fabric and the articles in accordance with the invention can be obtained from all conventional looped fabrics whether woven or knitted, for example the fabrics commonly known as Turkish towelling, and particularly textile materials formed of cellulose fibres or containing such fibres.
• fabrics which are suitable for this purpose mention can be made of those 3,547,750 Patented Dec. 15, 1970 which are formed of mixed textile yarns, such as cellulose yarns (cotton, linen) and animal yarns (wool, silk) and/or cellulose and synthetic yarns (nylon and the like).
• the articles in accordance with the invention can be bath towels, one face of which is untreated and therefore soft and absorbent whereas, on the other face, all or part of the terry loops are stiffened, which makes it possible to utilize this face of the towel for rubbing purposes.
• Another example consists in the treatment of face-cloths of the glove type, in which only the outer face is provided with hardened terry loops, with the result that the users hand is in contact with the soft internal face of the glove fabric; consequently, gloves of this type are very pleasant both to wear and to handle.
• One application which illustrates the stiffening of loops on both faces of the fabric is the manufacture of rugs and carpets, in particular mats for dogs.
• the method according to the invention consists in depositing on the loops to be stiffened an aqueous suspension of an emulsifiable thermoplastic resin containing triazine and a soluble salt of a metal of Group II of the Periodic Table of elements, and in drying the loops thus treated.
• the suspension utilized also contains a finishing resin of known type.
• thermoplastic resins By way of emulsifiable thermoplastic resins, mention can be made of the acrylic, methacrylic and/or vinyl resins which are particularly suitable. Thus, successful use can be made of commercially available aqueous emulsions of polyacrylates of methyl, ethyl, butyl etc., of the corresponding polymethacrylates, of acrylomethacrylic copolymers such as, for example, a copolymer of ethyl and of methyl methacrylate; polymers of this type are found in commerce under trade names such as Perapret F, Ucecryl PO, and others.
• aqueous emulsions of polymers or copolymers such as polyvinyl acetate, or alternatively polyvinyl formate, propionate or chloride; also suitable for the purpose are the emulsions 0f the copolymer of polyvinyl chloride and polyvinyl acetate.
• Suitable vinyl resins are marketed under the trade-marks Rhodoplas, Afcolac, Mowilith, etc.
• the salt of a metal of Group II of the Periodic Table of elements which serves as catalyst can be, for example, a chloride, sulphate, nitrate, perchlorate, chloroacetate etc. of zinc, beryllium, magnesium, calcium or any other alkaline-earth metal.
• triazine it is possible to employ the technical product of the type which is marketed under the trademark Stabitex D 46 and which contains approximately 50% triazine.
• such a resin is advantageously selected from the polyethers of ethylene-glycol or polyoxy-ethylene compounds, and particularly useful is a diester of a condensation product of formaldehyde with ethylene glycol; thus, diglycol-formal diacetate is especially suitable.
• a known thickening agent such as, for example, the watersoluble condensation product obtained by the reaction of urea and formaldehyde, a polyvinyl alcohol or the like.
• composition of the suspension can vary over a fairly wide range depending on the required degree of stiffening of the loops, the nature of the resin and of the fabric to be treated, and also depending on other conditions, the proportions of constituents indicated above are usually of the order of:
• the proportion of thermoplastic resin is approximately 40 to 55% of the total constituents except water.
• the aqueous suspension can be applied on the looped fabric by any known means such as coating, spraying or impregnation.
• the spray atomization system is of particular interest and highly convenient in practice, especially in the form of either one or a number of feed-racks which are employed for the purpose of spraying very small droplets of the suspension onto the fabric.
• the operation is usually performed on looped pile fabric which has undergone bleaching followed by drying after delivery from the loop.
• the quantity of suspension to be employed per square meter of fabric varies according to the nature of the fabric, the composition of the suspension and the degree of stiffening which is sought. As a rule, the quantity is of the order of 50 ml. to 800 ml. per square meter of surface but, in the majority of cases, varies between 100 and 300 ml.
• the fabric is subjected to a drying process which can take place at any temperature which is compatible with the heat resistance of the textile being processed and the constituents employed; the drying process can be performed, for example, between room temperature and 200 C., but rapid drying without causing damage to the material is obtained preferably between 100 and 15 0 C. In the vicinity of 15 0 C., only a few minutes are required for the loop fabric to be ready for use.
• a drying process which can take place at any temperature which is compatible with the heat resistance of the textile being processed and the constituents employed; the drying process can be performed, for example, between room temperature and 200 C., but rapid drying without causing damage to the material is obtained preferably between 100 and 15 0 C. In the vicinity of 15 0 C., only a few minutes are required for the loop fabric to be ready for use.
• EXAMPLE 1 With a view to converting terry-cloth bath towels (of Turkish towelling material) to rubbing-down towels, 1 liter of aqueous suspension was sprayed onto 5 square meters of this fabric, that is to say onto towels, and was prepared as follows:
• the quantity of water added to this mixture was such that the final volume was 1,000 ml.
• the suspension obtained therefore contained the following proportions per liter as expressed in dry substance:
• the treated fabric was dried in an air stream at approximately l10130 C.
• EXAMPLE 3 A suspension which was similar to the one described in Example 1 was prepared with 17.5 g. of polyvinyl acetate instead of 15 g. It was employed for the purpose of coating looped pile carpets on both sides and in a proportion of 0.25 liter per square meter. Drying was effected at 150 C. in approximately three minutes.
