Definitions

  • the web While supported in an unstretched condition, the web is immersed in a bath of liquid treating medium maintained at a temperature above the temperature at which the original texture was imparted to the fabric but below the glass transition temperature of the fibers.
  • the liquid medium is caused to flow concurrently at a predetermined relative velocity with respect to the web to control the degree of web texture.
  • the Web is thereafter cooled so that the texture is uniformly reset at the higher elastic memory.
  • the yarns In synthetic textile materials, such as polyesters, polyamides, polyacrylics and triacetate filaments, the yarns generally consist of bundles of filaments or fibers which have been texturized to impart the desired bulk, appearance and hand thereto.
  • the texture is generally provided by crimping, curling, bending or otherwise offsetting the synthetic filaments at an elevated temperature above the temperature at which they take a permanent set and substantially below the glass transition temperature.
  • the elastic memory of these materials is such that the texture will be maintained in the fibers or filaments at temperatures below the temperature at which they were set. However, the oifsets can be pulled out and destroyed at temperatures above their set temperature.
  • the texture providing offsets are important in providing the desired natural appearance, bulk and hand to the completed textile fabric. Where the textile fabric is subjected to temperatures higher than the temperatures at which the texture was set in subsequent processing operations and in use of the fabric, the texture is partially or completely obliterated or destroyed thereby impairing the desired natural appearance, bulk and hand of the fabric.
  • the present invention provides an improved method of treating a textile fabric web formed of synthetic fibers "ice which have been texturized at a predetermined elevated temperature in a manner so as to uniformly reset the original texture providing offsets in the filaments or fibers and so as to uniformly set the interlacing loops and offsets in the yarns.
  • the method contemplates supporting the fabric web in an open, relaxed condition with the fibers in unstretched condition and the texture providing offsets and the interlacing loops and offsets maintained therein.
  • the fabric web is immersed in a liquid treating medium heated to a temperature higher than that at which the texture was imparted to the synthetic fibers and also higher than the temperatures to which the fabric is normally subjected in the subsequent processing and use thereof, but at a temperature below the glass transition temperature of the material.
  • the liquid medium is caused to flow concurrently at a predetermined relative velocity with respect to the web.
  • the process may be modified to allow for the shrinkage, both in the longitudinal and transverse directions, by overfeeding of the fabric web on to the apparatus at a rate equal to the percentage of longitudinal shrinkage and by adjusting the width of the apparatus to allow for the transverse shrinkage of the fabric web as the web passes through the treating zone.
  • the texture providing offsets have been uniformly reset and the interlacing loops and offsets have been uniformly set at a relatively high elastic memory so that it can thereafter withstand normal processing and usage while still maintaining its texture and its natural appearance, bulk and hand.
  • a textile fabric web formed of synthetic fibers which have been textured, can be rapidly treated at a predetermined elevated temperature in a manner so as to uniformly reset the texture providing crimps and offsets in the filaments or fibers and so as to uniformly set the interlacing loops and offsets in the yarns, whereby the treated fabric web can withstand normal processing and usage while maintaining its texture, natural appearance, bulk and hand.
  • the textile fabric web is continuously fed on to an apparatus at a predetermined controlled rate and is supported thereon in an open, relaxed condition with the fibers in unstretched condition with a minimum of tension so that the texture providing offsets and the interlacing loops and olfsets formed in the yarn are maintained therein.
  • Any suitable apparatus may be employed which will convey a fabric web at a given speed.
  • Such an apparatus may be a tenter frame which employs pins or clips to support the fabric web at a controlled width between a pair of moving rails.
  • the fabric web is continuously fed onto such an apparatus and is maintained at a predetermined controlled width and at a fixed rate of speed.
  • the feeding means is set at a controlled rate of overfeed with the fabric web supported on the apparatus in an unstretched, relaxed condition; the overfeed being substantially equal to the shrinkage of the fabric web in the longitudinal direction after the web has passed through the treating zone.
  • the width of the apparatus may be reduced gradually to a width substantially equal to the shrinkage of the fabric web in the transverse direction. The adjusted width is generally con- 3 trolled while the fabric web is passing through the treating zone.
  • the feed of the fabric web onto the apparatus will be substantially equal to the speed of the supporting means of the apparatus so as to maintain the fabric web in an open, unstretched and relaxed condition.
  • the velocity of the web being conveyed on the apparatus may be as slow as 1 ft./second and is preferably 1 to 15 ft./second.
  • a treating zone to uniformly reset the texture Providing crimps and offsets in the filaments or fibers and to set the interlacing loops and offsets in the yarns at a relatively high elastic memory is provided and is disposed in the path of movement of the fabric web.
  • a liquid treating medium or bath which is maintained at an elevated temperature higher than that at which the texture was imparted to the synthetic fibers and also higher than the temperatures to which the fabric is normally subjected in subsequent processing and use thereof but at a temperature below the glass transition temperature of the fabric web, is disposed in the treating zone so that the web is immersed therein and passes therethrough.
  • the treating time of the fabric web is such that the web will be undamaged by the action of the liquid treating medium and yet sufficient to raise the temperature of the web to substantially that of the liquid treating medium but below the glass transition point of the web.
  • Suitable treatment times may be as short as approximately 1 second and as long as 15 seconds, and preferably are approximately 3 to 7 seconds.
  • the texture of the fabric web is maintained and the elastic memory of the texture providing crimps and offsets in the filaments or fibers is raised to a temperature higher than that previously imparted thereto, which elastic memory is also imparted to the interlacing loops and oifsets of the yarns.
  • the treated fabric web is then withdrawn from the liquid treating medium by the supporting apparatus without the application of additional forces. Any force exerted on the fabric web at this point in the process will alter the texture of the web, i.e., a longitudinal force may remove all or part of the texture longitudinally of the web and transverse force may remove all or part of the texture transversely of the web.
  • the withdrawn treated fabric web is passed to a cooling and washing bath which is maintained at a temperature lower than the temperature of the treating liquid and will uniformly reset the texture providing crimps and offsets in the filaments or fibers and uniformly set the interlacing loops and offsets of the yarns, as well as remove excess treating liquid from the web.
  • the temperature of the washing bath is generally at ambient temperature, for economy, but may be controlled at lower than ambient temperature or, as stated above, below the temperature of the treating liquid.
  • the web may be dried or may be further processed by applying finishing treatment materials, such as dyes, anti-static agents, UV absorbers, or the like.
  • this may be accomplished by controlling the tension of the web, by controlling the rate of feed and/or width of the web, or by controlling the flow and/or direction of the liquid treating medium.
  • the flow rate of the liquid treating medium may be increased in the direction of movement of the web, or may flow counter to the direction of move ment of the web feed to increase the degree of texture.
  • the liquid treating medium may comprise any of the polyhydric alcohols, alkylene carbonates, or mixtures thereof. Also, the liquid treating medium may comprise a mixture of any of the polyhydric alcohols and diglycolic acid or phosphoric acid. Examples of polyhydric alcohols are ethylene or diethylene glycol, propylene or dipropylene glycol; examples of alkylene carbonates are ethylene or diethylene carbonate, propylene or dipropylene carbonate.
  • the boiling points of various polyhydric alcohols which may be employed are as follows:
  • the temperature of the liquid treating medium may vary widely, and may be as low as approximately 300 F. or as high as 450 F. or more, depending upon the use to which the fabric web will be subjected and the type of synthetic material being treated. For example, the following table sets forth the glass transition points of several widely known synthetic materials:
  • the set temperature may be as high as 350-450 F. However, if the material is to be used, for example, as a rug, then the set temperature need only be high enough to withstand processing and finishing, such as dyeing procedures, since a rug will not normally be subjected to temperatures above boiling water, i.e., 212 F.

  • FIG. 2 is a top elevational view of the supporting means of the apparatus in which the fabric web is shown mounted thereon prior to and after it has passed through the treating zone.
  • the apparatus is a modified pin type tenter frame in which an offset is provided for immersing the fabric web in the treating medium.
  • the fabric web formed into a roll 10 is passed through a feeding means 12 and mounted on pins 14 of tenter chain 16.
  • the fabric web is supported thereon by pins 14 in an open, relaxed and unstretched condition by providing the width of the tenter frame to be substantially equal to the fabric web.
  • the fabric web is fed onto the tenter frame at a controlled rate of overfeed substantially equal to the percentage of shrinkage of the web in the longitudinal direction thereby providing for longitudinal shrinkage of the fabric web.
  • the tenter chain 16 is modified so that an offset 18 is provided in which the offset carries the fabric web through treating medium 20.
  • a suitable trough 22 is provided with conduit means 24 for circulating the treating medium 20, preferably in the direction of travel of the fabric web.
  • Conduit means include inlet conduit 26 and outlet conduit 28.
  • Outlet conduit 28 is connected to a suitable pump on the intake side thereof and inlet conduit 26 is connected to the outlet side of the pump.
  • a heating means to maintain the temperature of treating medium 20 is interposed into the conduit means 24.

  • the width of the tenter frame is adjusted gradually to a predetermined width to allow for the percentage of transverse shrinkage of the fabric web, as illustrated in FIG. 2.
  • the tenter frame is provided with means for adjusting the width thereof in which the sprockets for mounting the tenter chain 16 are provided with adjusting means for adjusting the tenter frame inwardly and outwardly.
  • the longitudinal shrinkage of the fabric web is provided by the amount of overfeed of the fabric web when fed onto the pins of the tenter chain.
  • the shrinkage both in the longitudinal and transverse direction, is controlled so that the treated fabric web is in an open, unstretched and relaxed condition whereby the texture providing offsets of the filaments and the interlacing loops and offsets of the yarns are maintained therein.
  • the width of the fabric web 10 is increased as it passes through the treating medium so as to remove or partially remove the degree of texture in the transverse direction originally imparted to the fabric web, as desired.
  • the texture may be modified in the longitudinal direction by underfeeding the fabric web onto the pins of the tenter chain 16.
  • a predetermined degree of texture is removed both in the longitudinal and transverse directions.
  • the fabric web after passing through treating medium 20 is removed from the tenter frame and passed through a washing bath 30 which is maintained at a temperature lower than the temperature of the treating medium whereby the texture providing crimps and offsets in the filaments or fibers are uniformly reset and the interlacing loops and offsets of the yarns are uniformly set at a relatively high elastic memory substantially equal to the temperature of the liquid treating medium. Thereafter the fabric web is rinsed to remove any excess treating medium and dried for subsequent use as desired.
