Definitions
- the present disclosure relates to a durable waterproof seam-joining structure with at least one seam that seals at least a first and second composite layer in a waterproof manner using adhesive material, wherein the first and second composite layers comprise membrane layers.
- the present disclosure further relates to a textile article, like a garment, with such seam-joining structure, and to a method and apparatus for manufacturing such seam-joining structure.
- Textile articles like clothing articles, can be made waterproof by arranging a waterproof water-vapor-permeable functional layer like a membrane, e.g. on the inside of the outer material of such article (which, in case of garments, are often called functional garments).
- a textile liner can be arranged on the side of the functional layer facing the body of the user of the clothing article.
- Functional garments are often made of functional protective materials, such as membrane laminates, to provide the wearer with specific properties.
- the membrane laminates have a function of protecting the wearer from the threat to his/her well-being, such as rain, snow, wind, temperatures, chemicals or blood pathogens.
- membrane laminates include porous polytetra- fluoroethylene membranes, porous or monolithic polyurethane membranes, and polyetherpolyester.
- garments are often sewn together from several pieces in order to achieve a specific fit, strength, durability, and/or optical appearance.
- multilayer laminates of the above-mentioned type When multilayer laminates of the above-mentioned type are used, individual cuts of the garment are cut out from laminate webs and then joined to form the garment.
- two laminate webs of the garment are thereby joined to each other by a sewing seam in a seam area.
- the functional layer of the laminate is perforated by such sewing, so that the waterproofness of the functional layer is adversely affected and undesired leaks can occur at the seam location.
- a seam sealing provides a barrier function comparable to the membrane laminate.
- such seams are covered by a thermoplastic seam tape.
- the tape is softened by hot air and applied over the seam by a specialized machine.
- Such tape most commonly includes at least two layers where one layer has a melting point higher than the other layer. This allows the hot air sealing machine to melt the lower melting sealing layer, leaving the higher melting layer intact as a carrier.
- thermoplastic adhesives are often used to seal fabric seams, such as adhesives made from polyurethanes, PVC, polyesters and polyamides.
- thermoplastic adhesives suffer from numerous disadvantages including tempera- ture limitations, limited durability and resistance to hydrolysis, and susceptibility to some chemicals.
- WO 01/26495 A describes the use of silicone for sealing seams.
- a seam seal that protects protective barrier fabrics by employing a seal- ing backer that seals the protective barrier fabrics over their seam joints with a silicone sealant layer.
- the silicone layer provides a seal between the sealing backer and the seamed protective barrier fabric panels and adheres the sealing backer to the seam.
- the protective barrier in the sealing backer and the protective barrier in the fabric are selected such as to allow impregnation of liquid uncross-linked silicone into the pores of the sealing backer protective barrier and into the pores of the fabric protective barrier.
- such sealed seams still suffer from degradation of waterproofness over lifetime, particularly over a multitude of washing cycles of the fabric. It would be beneficial to provide a seam-joining structure of the type as mentioned above that contributes to creating a durable and waterproof functional garment.
- the present invention relates to a seam-joining structure with features according to claim 1.
- the invention also relates to a textile article, particularly a garment, with such seam-joining structure according to the features of claim 15.
- the invention also relates to a method of manufacturing a seam-joining structure according to the features of claim 17.
- the invention also relates to an apparatus for manufacturing a seam-joining structure according to the features of claim 26.
- a seam-joining structure comprising at least a first composite layer and a second composite layer, a seam area comprising at least one seam that joins the first and second composite layers, at least one protective layer which covers the at least one seam, and an adhesive material which generates a liquid proof seal in the seam area and which bonds the at least one protective layer to the seam area.
- Each of the first and second composite lay- ers comprises at least one porous membrane layer with pores and with a first side, and a barrier layer joined to the at least one porous membrane layer opposite the first side and which is a barrier for the adhesive material, wherein at least in a portion of the seam area the pores of the respective porous membrane layers between the respective first side and the respective barrier layer are completely filled with the adhesive material.
- the composite layers may be waterproof and water vapor permeable composite layers.
- the adhesive material also acts as a sealing material in providing the liquid proof seal.
- a method of manufacturing a seam-joining structure which comprises at least a first composite layer and a second composite layer and a seam area comprising at least one seam that joins the first and second composite layers, wherein each of the first and second composite layers comprises at least one porous membrane layer with pores and with a first side, and a barrier layer joined to the at least one porous membrane layer opposite the first side.
- the method is comprising the steps of applying an adhesive material to the at least one seam in the seam area which generates a liquidproof seal such that in at least a portion of the seam area the pores of the respective porous membrane layers between the respective first side and the respective barrier layer are completely penetrated with the adhesive material through to the respective barrier layer which is a barrier for the adhesive material, and bonding at least one protective layer to the seam area by the adhesive material, such that the at least one protective layer covers the at least one seam.
- the adhesive material comprises silicone. According to a further embodiment, the adhesive material comprises a two- component room temperature curing adhesive material. According to another embodiment the adhesive material comprises a two-component curing silicone.
- the adhesive type used according to the invention provides a high hydrolysis resistance and temperature resistance compared to thermoplastic adhesives like PU based adhesive systems.
- the adhesive material comprises a viscosity lower than 6000 mPa s for penetration of the pores of the porous membrane layers, in particular before applying to the seam area.
- the viscosity is lower than 4000 mPa s.
- the viscosity is lower than 3000 mPa s.
- the viscosity is lower than 2000 mPa s.
- the adhesive material comprises a viscosity of 3500 mPa s for penetration of the pores of the porous membrane layers, in particular before applying to the seam area.
- the viscosity may be measured according to test method as described in ISO 3219 at a temperature of 23°C.
- a two component curing silicone adhesive material provides prompt and full penetration capabilities into the porous membrane structures. Full penetration may be reached at least after a certain time period depending on, for example, the type of membrane and adhesive viscosity.
- At least one or each of the composite layers comprises at least one porous membrane layer and a continuous non-porous layer.
- the continuous non-porous layer forms the barrier layer.
- the at least one porous membrane layer is at least one first porous membrane layer, and each of the first and second composite layers further comprises at least one second porous membrane layer attached to the barrier layer opposite to the first porous membrane layer.
- at least one of the first porous membrane layer and the second porous membrane layer is water vapor permeable and waterproof.
- the first porous membrane layer and/or the second porous membrane layer is water vapour permeable and air impermeable.
- At least one of the first porous membrane layer and the second porous membrane layer comprises expanded polytetrafluororethylene (ePTFE).
- ePTFE expanded polytetrafluororethylene
- porous membrane means any membranes with a permeable structure throughout the thickness of the membrane.
- the permeable structure comprises a nodes and fibril structure forming pores as exemplary shown in Figure 9.
- the pore size of the pores of the at least one porous membrane layer is in a range between 0.05 ⁇ to 10 pm, particularly from about 0.1 pm to about 1 pm, more particularly from about 0.15 pm to about 0.8 ⁇ .
- the barrier layer is a barrier for the adhesive material such that the adhesive material is hindered to penetrate through the barrier layer until the adhesive material has hardened. As such, the barrier layer does not need to be impermeable for the adhesive material as such.
- the barrier layer forms a border for the adhesive material such that in the manufacturing process the adhesive material cannot penetrate through the structure of the barrier layer and therefore is not visible on the side of the barrier layer opposite to the porous membrane layer. The barrier layer at least significantly slows down any penetration of the adhesive material into the barrier layer.
- the barrier layer is impermeable for the adhesive material.
