Definitions

• This invention relates to a textile attachment formation, a textile support assembly including an activated textile attachment formation, a casing assembly including the textile support assembly, a breast support arrangement including a textile support assembly or a casing assembly, a method of manufacturing a textile attachment formation, and a method of manufacturing a textile support assembly.
• adhesives for joining items together is well known.
• adhesives in the form of a liquid or a tape may be used to join a textile item formed of natural or synthetic fibres to another textile item or another substrate.
• the liquid or tape adhesive is formed in a pattern between the textile item and the other item and when the adhesive sets a bond is formed between the textile item and the other item.
• a textile attachment formation comprising a textile structure formed by a series of interlocking loops of a first thread, the textile structure further including an elongate bonding element lying adjacent to the first thread, the position of the bonding element about the perimeter of the first thread varying along the length of the first thread.
• Varying the position of the elongate bonding element about the perimeter of the first thread means that discrete portions of the bonding element are exposed on a given side of the attachment formation.
• discrete and discontinous bond formations are created on at least one side of the textile attachment formation.
• These discrete bond formations are sufficient to bond the attachment formation to another substrate, or to allow an attachment formation lying between first and second substrates to bond the first and second substrates together.
• the bond formations are discrete the textile attachment formation is able to retain the flexibility provided for by its interlocking loop structure, and so the or each substrate to which the textile attachment formation is bonded is similarly able to maintain any inherent flexibility.
• the position of the bonding element relative to the perimeter of the first thread varies randomly.
• a random variation of position simplifies the manner in which the textile attachment formation may be manufactured while maintaining the formation of discrete bond formations on activation of the bonding element.
• portions of the bonding element exposed on a first side of the textile structure define discrete bonding regions. Having a first side of the structure define discrete bonding regions ensures that the textile attachment formation is adherable to at least one substrate in a manner whereby the attachment formation and the substrate maintain their flexibility.
• the textile structure further includes a second thread lying alongside the first thread.
• a second thread allows the textile attachment formation to utilise two smaller diameter threads, so as to increase the inherent flexibility of the formation, while maintaining the same tensile strength as provided by a single, larger diameter thread.
• the selective sandwiching of the elongate bonding element between the first and second threads results in the formation of bond formation (between the first and second threads) which is not exposed beyond the first and second threads.
• Such a hidden bond formation does not contribute to the bonding of the attachment formation to a substrate or between substrates and so further maintains the flexibility of the bonded arrangement.
• At least one of the first thread and/or the second thread may be a multi-filament thread.
• the inclusion of a multifilament thread increases the inherent flexibility of the textile structure compared with the flexibility achieved with a monofilament thread of the same overall diameter.
• the spaces between adjacent filaments receive activated bonding element and so limit the amount of bonding element which is exposed on a given side of the textile attachment formation. This helps to ensure that the size of exposed bond formation is sufficient to ensure adequate adhesion but not so large as to degrade the flexibility of the bonded arrangement.
• the diameter of the elongate bonding element is smaller than the diameter of the first thread or both the first thread and the second thread. Having a smaller diameter bonding element helps to ensure that it is easily incorporated within the interlocking loops of the textile structure. It also limits the volume of bonding element that is introduced into the structure on activation of the bonding element.
• the textile structure defines an elongate hollow structure. Having the textile structure define a hollow structure reduces the difficulties that might otherwise be associated with finishing edges of the textile attachment formation while maintaining a desired degree of flexibility.
• the hollow structure is a hollow tubular structure.
• the inclusion of a hollow tubular structure helps to reduce kinking of the textile attachment formation, e.g. as it is formed into a pattern between substrates.
• a textile support assembly for a breast support arrangement, comprising a resiliently deformable curved support member including first and second ends, each of the first and second ends having an activated textile attachment formation as described hereinabove adhered thereto, the or each activated textile attachment formation being adhered to the support member by a plurality of discrete first bond formations.
• the inclusion of at least one textile attachment formation allows the textile support assembly of the invention to be readily incorporated into a support arrangement, e.g. a breast support arrangement, via essentially conventional assembly steps, i.e. essentially conventional textile-based assembly steps.
• the or each activated textile attachment formation defines an elongate hollow structure, each elongate hollow structure receiving a respective first or second end of the support member.
• the inclusion of an elongate hollow structure provides a convenient way of engaging the or each textile attachment formation with the corresponding end of the support member.
• the hollow structure of one activated textile attachment formation is integrally formed with the hollow structure of the other activated textile attachment formation. Such an arrangement allows the hollow strcuture to be constructed as a single article which streamlines manufacture of the textile support assembly, and so helps to reduce manufacturing costs.
• Portions of the first thread may be bonded to one another by discrete second bond formations. Bonding portions of the first thread to one another helps to ensure that the or each elongate hollow structure remains in a desired configuration, e.g. in frictional engagement with the support member.
• a casing assembly for a breast support arrangement, comprising a hollow tubular textile casing having first and second casing ends and within which lies a textile support assembly as described hereinabove, the or each activated textile attachment formation of the textile support assembly being secured relative to a corresponding casing end. Securing the or each activated textile attachment formation in the aforementioned manner inhibits movement of the textile support assembly relative to the casing and so avoids incorrect positioning of the support member within the tubular textile casing and squeak difficulties. Meanwhile the discrete and discontinuous nature of the bond formations means that the textile support assembly maintains its flexibility and so the casing assembly is comfortable when incorporated in a garment.
• the or each activated textile attachment formation may be secured relative to a respective casing end by one or more stitches.
• Such stitches can be readily incorporated within a garment assembly process since stitching is very likely to be utilised elsewhere in the garment.
• a breast support arrangement incorporating a textile support assembly as described hereinabove.
• a breast support arrangement incorporating a casing assembly as described hereinabove.
• the aforementioned breast support arrangements share the benefits associated with the corresponding textile support assembly and casing assembly.
• a method of manufacturing a textile attachment formation comprising the steps of:
• Varying the position of the bonding element about the perimeter of the first thread means that discrete portions of the bonding element are exposed, and so when the bonding element is activated discrete and discontinuous bond formations are created on at least one side of the textile attachment formation.
• Such discrete bond formations are able to provide sufficient bonding while allowing the textile attachment formation to maintain its flexibility once bonding has taken place.
• the step of wrapping an elongate bonding element around a first thread includes wrapping the elongate bonding element around the first thread in a random manner. Such a step reduces the control required in the manufacturing process and so allows it to be carried out using relatively simple machinery and relatively unskilled operatives.
• a textile support assembly comprising the steps of:
• the step of engaging the textile attachment formation with each of the first and second ends includes inserting each end into an elongate hollow structure of the or each textile attachment formation.
• Such a step may be readily carried out by an automated manufacturing process.
• a preferred method of manufacturing a textile support assembly further includes stretching the or each elongate hollow structure in a lengthwise direction to frictionally engage the said elongate hollow structure with at least a corresponding first or second end of the support member.
• Stretching of the or each elongate hollow structure secures the or each structure to the support member to a desired initial extent.
• activating the or each textile attachment formation includes melting the bonding element.
• Such activation can be readily carried out during a manufacturing process in a controlled manner, e.g. by heating and/or ultrasonic vibration.

• a textile attachment formation according to a first embodiment of the invention is designated generally by the reference numeral 10.
• the textile attachment formation 10 has a textile structure 12 which is formed by a series of interlocking loops 14 of a first thread 16.
• the first thread 16 is a multi-filament sewing thread 18.
• a sewing thread is a thread which achieves the minimum tenacity prescribed in ISO4915; 1991.
• Suitable multifilament sewing threads 18 include polyamide or polyester threads such as Coats' Epic®, Gral® Delta®, or Seamsoft® threads, or Oxley's Lubrilox® or Aptan® threads.
• the first thread 16 may be a monofilament thread.
• the textile structure 12 also includes an elongate bonding element 20 which lies adjacent to the first thread 16, as shown in Figure 1 (bonding element 20 only shown on one course of loops 14 for clarity).
• the bonding element 20 is or includes a thermoplastic material such as any of polyamide, polyester, polyurethane, polyurethane urea, or polypropylene, or a combination of any of these materials.
• the bonding element 20 is formed from a low melt, i.e. less than 110 0 C, monofilament yarn such as Luxilon Industries NVs Thermolux® yarn or EMS Chemie AG's Grilon® yarn.
• the diameter of the bonding element 20 is smaller than the diameter of the first thread 16. In the embodiment shown the diameter of the bonding element 20 is approximately one fifth of the overall diameter of the first thread 16. In other embodiments of the invention (not shown) the ratio of the diameter of the first thread 16 to the diameter of the bonding element 20 can lie in the range 2:1 to 10:1.
• the position of the bonding element 20 about the perimeter 22 of the first thread 16 varies along the length of the first thread 16, as shown in Figures 2(a) to 2(d). In the embodiment shown, the position of the bonding element 20 about the perimeter 22 varies randomly.
• a first side 24 of the textile structure 12 includes a number of regions in which a portion of the bonding element 20 is exposed. As such the first side 24 defines a plurality of discrete bonding regions 26.
• the textile structure 12 also defines an elongate hollow structure 28, and in particular a hollow tubular structure 30, as shown in Figure 3.
• the textile attachment formation 10 is positioned as desired relative to a substrate, or between two substrates.
• the bonding element 20 is then activated, e.g. melted by heating.
• the bonding element 20 flows into the spaces between adjacent filaments 32 in the multifilament first thread 16, as shown in Figures 4(a) to 4(d).
• Second discrete bond formations 36 form between respective portions of the first thread 16 where the said portions overlap one another.
• first and second discrete bond formations 34, 36 are sufficient to provide a desired degree of bonding but their discrete and discontinuous nature allows the textile attachment formation 10 to maintain the flexibility provided by its interlocking loop 14 structure and so, in turn, the or each substrate is able also to maintain its inherent flexibility.
• Figure 6(a) shows a cross-sectional view through a section of textile attachment formation 50 according to a second embodiment of the invention.
• the second textile attachment formation 50 shares a number of features with the first textile attachment formation 10 and these features are designated using the same reference numerals.
• the second textile attachment formation 50 differs from the first textile attachment formation 10 in that its textile structure 12 is formed by a series of interlocking loops of first and second threads 16, 52.
• the second thread 52 is also a multifilament sewing thread 18 but the respective diameters of the first and second threads 16, 52 in the second textile attachment formation 50 are smaller than the diameter of the first thread 16 in the first textile attachment formation 10.
• the inclusion of two smaller diameter first and second threads 16, 52 means that the second textile attachment formation 50 can have the same tensile strength as the first textile attachment formation 10 but an even more flexible structure.
• third bond formations 54 are created between overlapping first and second threads 16, 52, as shown in Figure 6(c). These third bond formations 54 are not exposed and so do not contribute to the bonding of the second attachment formation 50 to one or more substrates.
• Each of the first and second textile attachment formations 10; 50 is made by wrapping the elongate bonding element 20 around the first thread 16 so as to vary the position of the bonding element 20 about the perimeter 22 of the first thread 16 as the bonding element 20 extends along the length of the first thread 16.
• the combined bonding element 20 and first thread 16 is then formed into a series of interlocking loops 14 to create the textile structure 12.
• the series of interlocking loops 14 may be formed by knitting, and in particular may be formed by a circular knitting machine.
• the bonding element 20 may be wrapped around the first thread 16 as it enters the knitting machine. Such wrapping tends to twist the bonding element 20 around the first thread 16 in a random manner.
• a textile support assembly according to a third embodiment of the invention is designated generally by the reference numeral 70.
• the textile support assembly 70 includes a resiliently deformable support member 72 that has first and second ends 74, 76, as shown in Figure 7.
• the support member 72 is formed from a metal. In other embodiments of the invention (not shown) the support member 72 may be formed from another resiliently deformable material such as a plastics material.
• Each end 74, 76 has an activated textile attachment formation 78 secured relative thereto.
• Each activated textile attachment formation 78 has essentially the same textile structure 12 as the first textile attachment formation 10 mentioned above. However, in activated form the bonding element 20 has been activated, e.g. melted, and so the textile structure 12 includes a plurality of discrete first and second bond formations 34, 36.
• each activated textile attachment formation 78 receives a respective first or second end 74, 76 of the support member 72.
• each elongate hollow structure 28 frictionally engages with the corresponding end 74, 76 of the support member 72.
• Portions of the first thread 16 are bonded to one another by the discrete second bond formations 36 so as to maintain each elongate hollow structure 28 in frictional engagement with the corresponding end 74, 76 of the support member 72.
• each activated textile attachment formation 78 which extends beyond the respective end 74, 76 of the support member 72 adopts a flattened cross-sectional profile.

• each activated textile attachment formation 78 remains flexible and so can be readily penetrated by a sewing needle to allow securing of each formation 78 within a breast support arrangement by one or more stitches.

• the elongate hollow structures 28 are integrally formed with one another and together define a single hollow tubular structure 30.
• the hollow tubular structure 30 frictionally engages with the whole of the support member 72 (shown in dashed line in Figure 9).
• FIG. 10 shows a partially sectioned view of a casing assembly 110 according to another embodiment of the invention.
• the casing assembly 110 includes a hollow tubular textile casing 112 which has first and second casing ends 114, 116.
