  • a further object of this invention is toprovide altered cellulose fiber-containing garments, the new shapes of which are retained on laundering.
  • a still further object of this invention is to obviate difficulties previously encountered in attempting to alter cellulose fiber-containing garments having permanent cuffs, pleats or similar types of folds.
  • a particular object of this invention is to provide a method for cufiing permanently'set cellulose fiber-containing trousers and also for removing and relocating the permanently set cuffs of cellulose fiber-containing trousers.
  • FIG. 1 is a fragmentary view of a permanently set seam in a garment
  • FIG. 2 shows the opened seam of FIG. 1
  • FIG. 3 shows a take-up in the seam of FIG. 2 to a new position
  • FIG. 4 shows the new seam after permanent setting according to the process ofthis invention
  • FIG. 5 is a view, in perspective of the lower part of an uncuffed leg of a pair of permanently set trousers
  • FIG. 6, is a cross-sectional view taken along the line 6 6 of FIG. 5, showing the seams of the uncuffed trouserleg; v p 7 FIG. 7 is a view in perspective of the trouser leg of FIG. 5, cuffed and permanentlyset, and
  • FIG. 8 is a cross-sectional view taken along the line 88 of FIG. 7, showing thev seams of the cuffed trouser leg. 1
  • Points x and x are positions selected at random along the surface of the garment in order to illustrate the resetting of the garment seam.
  • seam 12 has been opened and points x and x are located on either side of the opened seam.
  • FIG. 4 shows the panels 10 and 11 of the permanently set garment joined along new seam 13 after the garment has been treated according to the method of the invention.
  • FIGS. 5-8 illustrate the application of the method of this invention to the cufiing of uncuft'ed permanently set trousers.
  • points P, Q, R, S and T along the crease of the uncutfed trousers are selected in order to illustrate the formation of a cuff.
  • points P, Q, R, S and T are shown in the position they occupy in trousers cuffed according to the method of this invention.
  • a permanently set cellulose fiber-containing garment having at least one permanent fold is selected and a new configuration including a change in the fold position or direction is arranged. Thereafter, a solution of an acidic catalyst hereinafter described, is applied to the area of the new configuration of the garment, and the garment is pressed and simultaneously or subsequently heated to reset the new configuration.
  • an acidic catalyst hereinafter described
  • the acidic catalyst solution may be applied to the permanent-set garment before the garment is arranged in a new configuration. As before, the garment is then rearranged, pressed and heated to reset the new configuration.
  • the method of this invention is of particular utility in cuffing or recufling permanently set trousers.
  • the uncuffed trousers are folded so as to form a cuff at the bottom of each leg and the catalyst solution is applied to the folds in the trouser legs.
  • the trousers are then pressed and simultaneously or subsequently heated, thereby forming the cuffed legs.
  • the catalyst solution can first be applied to the trousers and thereafter the cuffs could be arranged and formed in the garment.
  • the 'cuffing of permanently set, uncuffed trousers involves the repositioning of a fold (at the crease of the trousers) and the setting of a new fold. Such repositioning of a permanently set fold could not be satisfactorily effected by techniques formerly used.
  • the trousers are folded so as to form a new cuff at the bottom of each leg and the catalyst solution is applied to the new folds as well as to the folds of the original cuffs.
  • the trousers are then pressed and simultaneously or subsequently heated,
  • the acidic catalyst used in this invention can be an organic acid alone or in combination with the metal salt of an inorganic acid.
  • the organic acids which are preferably.,-used1are water soluble, non-volatile, hydroxy acids yielding-a pH-of about 3.0 togabout 5.0 in a 1 normal aqueous solution. Usually, these acids should have a boiling .pointdiigher than about 120 C; Among'the suitable bodim ents of this invention. Unless otherwise indicated allparts given are by weight,and all garments or garment organic acids maybe included citric, lactic, tartaric, glyshould be noted that, although the catalyst system is usually applied in thellform of an aqueous solution, the useof non-aqueous solvents is sometimes preferred.
  • the extent of pressing'an'd heating is important to the success of this invention.
  • One common failing of prior art techniques was the inability to strike a proper balance between pressing times and temperature. Heretofore, when elevated temperatures were employed, the garment would often tear and disintegrate due to degradation of the fabric.
  • prior art treatments employing lower tetrnperatures without the aid of a catalyst system were unable to give durable creases.
  • the method of this invention can accomplish recreasing of permanently set garments merely by pressing at temperatures of from about 220 F. to about 276 F.
  • the duration of the pressing may be varied as desired and can range, for example, from 30 seconds to about 10 minutes.
  • cuffs and other folds can merely be pressed to impart shape to the folds and then cured in an oven maintained at a temperature of from about 200 F. to about 450 F. for from about 30 seconds to about 10 minutes.
  • the acid catalyst present on the garment may be neutralized by a buffering agent such as a weak base or a basic salt.
  • the acidic catalyst may be applied to the garment by any of the conventional means such as padding, dipping, spraying, and the like.
  • the catalyst solution contains from about 1% by weight of the acidic material to a saturated solution, and preferably from about 2.5% to about by weight of the acid.
  • the catalyst is a mixture of an organic acid and an acid salt
  • the catalyst solution contains from about 1% acid: 0.1% salt, by weight to a saturated solution of the combination of acid and salt.
  • the solution of the catalyst mixture contains from about 2.5% to about 15 of organic acid and from about 0.25% to about 2.0% of salt.
  • the weight pickup of the catalyst solution by the garment may be varied as desired.
  • the method of this invention is applicable to perma nentiy set farments formed either completely from cellulose fiber-containing materials, such as cotton, rayon, linen, and the like, or blends thereof with other natural and synthetic fibers, such as wools, nylons, polyesters, acrylics, polyolefins and the like.
  • Such garments are permanently set in any desired configuration by chemical reaction carried out between cellulose and a crosslinking agent or resin precondensate in the presence of an acid catalyst.
  • the crosslinking reagents and resin precondensates include urea-formaldehyde, melamine-formaldehyde, methylol derivatives of cyclic ureas such as cyclic ethylene, urea-formaldehyde, dimethylol ureas and triazones, dimethylol carbamates, dimethylol imidazolidones, and the like.
  • the acid catalysts may be any of those commonly used in crosslinking cellulose such as magnesium chloride, zinc nitrate, zinc fluoroborate, amine and ammonium salts of inorganic acids, and the like.
  • EXAMPLE I An aqueous solution was prepared containing 3.5 parts of citric acid and 1.5 parts of a 30% solution of magnesium chloride per parts of solution. Garment sections'made from '8 oz. all-cotton twill sewn in 'the' form of uncufled trouserlegs and set creased (that is, pressed, creased and set)were wetted by spraying along the parts where the cuff. folds were to be formedwith the aqueous solution until these parts were impregnated to approximately 60-70% of their dry weight. The garment sections were then dried at room temperature and a cuff shape was introduced at the wetted and dried part according to the standard procedures known in the art for making cuffs on trouser legs. p
  • the cuffed sections were-then pressed on a leg-press of the type commonly used for garment'manufacturing and garment pressing.
  • The'cuffs were pressed at a temperature of 220,F.240 F. for 60 seconds, '90 seconds, seconds or seconds. Similar garment sections were cuffed without prior spraying. All cuffs were then laundered and tumble dried. After one such cycle the cuffs which had not been treated withthe solution described above showed no shape retention except for that which was imparted by the sewing. On the other hand, the cuffs treated wtih the aqueous solution of the acid and metal salt retained the shape and flatness of the end even after ten wash cycles.
  • EXAMPLE 2 An aqueous solution was prepared containing 3.5 parts of glycolic acid and 1.5 parts of a 30% solution of magnesium chloride were 100 parts of solution. Garment sections were then processed as in Example 1 using the above solution. The resulting cult creases were. sharp and flat and the cuffs were durable to repeated laundering and tumble drying.
  • EXAMPLE 3 An aqueous solution-was prepared containing 3.5 parts of tartaric acid and 1.5 parts of a 30% solution of magnesium chloride per 100 parts of solution.

  • EXAMPLE 17 (a) A solution of 3.5 parts of citric acid and 0.5 parts of magnesium chloride in 96.0 parts of water was sprayed upon the lower legs of a pair of cuffed, permanently set cotton twill trousers. After the trousers had been air dried, a new cuff was arranged in the trousers and the trousers were then pressed at a temperature of about 240 F. for 180 seconds. After the pressing and heating step, the trousers possessed sharp, flat cuffs in the new position, with no trace remaining of the original cuffs. The newly formed cuffs retained their sharp creases upon laundering.
  • Garment sections made from ---55% polyester: 45%- rayon blend fabric, sewn in the form of uncuffed trouser legs and set-creased were folded and sewn to form the desired cuff. These formed cuffs were impregnated with an aqueous solution. prepared with 4.5 parts of citric acid and 1.5 parts of a 30% aqueous solution of magnesium chloride per 100 parts of solution. The Wet cuffs'were dried on a press adjusted so as to effect further heat treatment of the cuffs in accordance with :thisinvention. Similar garment sections were also cuffed and impregnated with water only and pressed as above. All the cuffs were laundered and tumble dried. After one such cycle, the cuffs which had not been impregnated with the'solution described above showed no shape retention; however, the treated cuffs retained their shape even after :ten wash cycles.
  • EXAMPLE 19 A garment section was made from an 8 oz. all-cotton twill sewn in the form of a trouser leg and set-creased.
  • This garment section was then wetted with the aqueous solution described in'Exarnple- 1 and folded so as to form a crease in a new, previously flat area. This garment section was then air dried. After air drying, the trouser leg was pressed in the new configuration for 150 seconds. After the resulting garment section had been laundered ten times, the old crease virtually disappeared wherein the new crease retained its shape and sharpness.
  • EXAMPLE 20 Garment sections made from 8 oz. all-cotton twill, sewn in the form of uncuffed trouser legs and set-creased were processed as in Example 1 except that the dried and cuffed sections were pressed slightly to impart the shape of the cuff and then exposed in a forced air oven to the following heat cycles: minute, 5 minutes, 10 minutes ,at 240 F.; 1 minute, 3 minutes and 6 minutes at 2 F.
