Description

[Technical field]

[0001] The present invention relates to the field of textiles, and in particular to coating compositions suitable for imparting impact and abrasion resistance to the textiles to which they are applied.

[0002] The invention also relates to fabrics coated with such compositions and to garments utilizing such coated fabrics. [Background technology]

[0003] The use of proper clothing and equipment is essential for safe riding of motorcycles and similar vehicles.

[0004] However, motorcycle clothing is generally not suitable for everyday use.

[0005] Textiles, e.g., fabrics, using high strength, high performance yarns (e.g., Dyneema®, Spectra®, Kevlar®, etc.) are known for use in the manufacture of clothing and apparel suitable for use as motorcycle wear.

[0006] Such textile articles can be single or multi-layered fabrics made by using high tenacity, high performance yarns as described above, for example, high tenacity, high performance yarns interwoven with single layer fabrics (plain weave, twill, etc.) or multi-layered fabrics (by interlayer bonding, angle lock, binders, etc.) as known in the art.

[0007] However, known textile articles generally do not possess the aesthetic characteristics that would make a fabric or garment fashionable in the clothing industry, yet also suitable for everyday use.

[0008] There are also several chemicals known to be applied to substrates to provide abrasion and impact resistance.

[0009] US Patent No. 5,399,633 discloses an aqueous dispersion for applying a corrosion-resistant and weather-resistant coating to materials, particularly synthetic fiber fabrics. The aqueous dispersion disclosed in US Patent No. 5,399,633 includes polyvinylidene fluoride (PVDF), water, an acrylic copolymer, a pigment, a UV protectant, and a solvent (e.g., a low boiling alcohol). US Patent No. 5,399,633 discloses that the aqueous dispersion can be used to apply a corrosion-resistant and weather-resistant coating to heavy-duty fabrics used in the manufacture of inflatable hangars, tent roofs, and transport belts.

[0010] However, impact- and abrasion-resistant, soft and stylish textile products suitable for the manufacture of clothing and motorcycle wear cannot be obtained using currently known coating compositions. [Prior art documents] [Patent documents]

[0086] After the aqueous paste composition of the present invention is applied to at least a portion of a fabric, preferably denim, the fabric coated with the aqueous paste composition is dried to fix the coating to the fabric.

[0087] A further object of the present invention is to provide a process for producing a coated fabric, comprising the steps of: a) providing at least a fabric; b) coating at least a portion of the fabric with an aqueous paste composition; and c) drying the fabric obtained in step b) to fix the coating to the fabric.

[0088] Claim 13, which is an independent method invention, refers to an aqueous paste composition according to any one of claims 1 to 12. Thus, independent process claim 13 refers to an aqueous paste composition having the features according to any one of claims 1 to 12 and any combination thereof. In other words, the aqueous paste composition to which step b) of claim 13 refers can be any aqueous paste composition having the features according to any one of claims 1 to 12 and any combination thereof.

[0089] In accordance with the present invention, a coated fabric comprises a fabric and a coating.

[0090] As noted above, a suitable amount of the paste composition can be applied to at least a portion of a fabric by known methods, such as knife coating.

[0091] According to an embodiment, step c) includes a step of heating the fabric obtained in step b). In this case, according to an embodiment, the fabric to which the aqueous paste composition of the present invention is applied can be heated at a temperature in the range of 100° C. to 200° C., preferably 130° C. to 180° C. For example, the heating step can be continued for 1 to 5 minutes, preferably 2 to 4 minutes.

[0092] According to an embodiment, heating of the fabric having the aqueous paste composition applied thereto can be carried out in stages.

[0093] Thus, according to an embodiment, step c) of the process of the invention comprises heating the fabric obtained in step b) at a first temperature and heating said fabric at a second temperature, the second temperature being preferably higher than the first temperature.

[0094] For example, the fabric obtained in step b) of the method of the present invention, i.e. the fabric at least partially coated with the aqueous paste composition of the present invention, can be heated to a first temperature in order to dry the composition, followed by heating the fabric coated with the dried composition at a second temperature, preferably higher than the first temperature, in order to fix the coating to the fabric.

[0095] For example, the fabric to which the aqueous paste composition has been applied can be heated for 0.5 to 5 minutes, preferably 1 to 3 minutes, at a first temperature of 100° C. to 150° C., preferably 120° C. to 140° C. In this manner, the composition is dried together with the fabric.

[0096] The fabric coated with the dry composition can then be heated for 0.2 to 2 minutes, preferably 0.5 to 1.5 minutes, at a second temperature of 150° C. to 200° C., preferably 170° C. to 190° C. In this manner, the dry composition is fixed to the fabric.

[0097] According to an embodiment, the process may further comprise a softening step d).

[0098] In particular, in the softening step d), the coated fabric is subjected to mechanical stress, which increases the flexibility of the coated fabric, which advantageously reduces the stiffness of the fabric.

[0099] When the coated fabric is subjected to mechanical stress, it has been observed that the stiffness of the fabric decreases, while advantageously, impact and abrasion resistance are maintained.

[0100] Methods for softening coated fabrics by application of one or more mechanical stresses are known in the art.

[0101] For example, a suitable softening method is ball washing, where the coated fabric (or article containing it) is treated, for example, by washing in a washing machine, in the presence of a hard component (e.g., hard beads).

[0102] A further subject of the invention is a coated fabric as obtained through the process according to the invention, as described above.

[0103] According to one feature, the coated fabric obtained through the process of the present invention is a dry or nearly dry coated fabric.

[0104] Indeed, advantageously, the step of drying the fabric to which the composition of the present invention has been applied dries the composition on the fabric and fixes the composition to the fabric, in other words, the moisture (especially water) in the composition is removed or substantially removed from the composition on the fabric during the drying step.

[0105] According to an embodiment, the coating on the fabric is in the form of a matrix, for example a film.

[0106] For example, a coated fabric of the present invention can include a dry, or nearly dry, polymeric film that includes a binder, a material having a tensile modulus of at least 2000 MPa, and an antistatic agent.

[0107] For example, after drying, the binder in the composition of the present invention can form a film-like matrix that includes a material having a tensile modulus of at least 2000 MPa, such as polyvinylidene fluoride (PVDF), and an antistatic agent.

[0108] The material having a tensile modulus of at least 2000 MPa in the dried coating on the fabric, and the antistatic agent can be characterized by known methods, for example, the high tensile modulus formed particles, and the particles in the binder matrix can be identified by optical microscopy.

[0109] For example, the material having a tensile modulus of at least 2000 MPa (preferably polyvinylidene fluoride (PVDF)) and the antistatic agent can be extracted and separated from the coated fabric by known methods. After separation, the material having a tensile modulus of at least 2000 MPa and the antistatic agent can be characterized by known methods, such as, for example, spectroscopy and chromatography. For example, FTIR (Fourier transform infrared), Raman, GPC (gel permeation chromatography), and HPLC (high performance liquid chromatography) can be used to characterize the components of the coating on the fabric.

[0110] Furthermore, surface analysis can be carried out via FTIR in ATR (attenuated total reflection) mode. The spectrum obtained from the uncoated fabric is subtracted from the spectrum obtained from the same fabric when coated, to obtain, as the difference spectrum, the spectrum of the coating. In this way, it is advantageously possible to identify the components of the coating, in particular materials with a tensile modulus of at least 2000 MPa (e.g. PVDF or glass fiber).

[0111] As noted above, according to embodiments, after drying, the binder forms a matrix that can be decomposed by known methods so that small portions thereof can be detected and characterized by known techniques.

[0112] For example, a material having a tensile modulus of at least 2000 MPa (e.g., PVDF or glass fiber) can be extracted from the coating by dissolving the matrix formed by the binder using a suitable solvent. The extracted material can be analyzed, for example, by spectroscopy and / or chromatography to identify the material having a tensile modulus of at least 2000 MPa used in the coating.

[0113] For example, a qualitative analysis can be carried out to identify materials (e.g., PVDF and / or glass fibers) having a tensile modulus of at least 2000 MPa in a dry coating on a fibrous substrate by applying one or more of the following methods, which are known per se in the art: Non-destructive methods (i.e. analytical methods that do not destroy the dry coating) - XRD (X-ray diffraction), (direct analysis) - Solid-state NMR (nuclear magnetic resonance) - FTIR (Fourier Transform Infrared Spectroscopy) - Raman spectroscopy Destructive methods (i.e. analytical methods that destroy the dry coating) - Fluorine-19 Nuclear Magnetic Resonance ( 19 F NMR) - Viscosity measurement (after extraction) - XRD (X-ray diffraction), (after extraction) - Beilstein Halogen Test - Raman spectroscopy (post extraction)

[0114] According to an embodiment, a material having a tensile modulus of at least 2000 MPa, such as PVDF, glass fiber or a mixture thereof, can be present in the dry coating of the fabric as a powder, i.e. as particles. The particles are preferably micron particles, with a size ranging from 1 to 10 microns. The material can also be short fibers, such as short enough fibers, so as not to impair the final appearance of the fabric. The length of the fibers can be less than 5 mm, preferably less than 2 mm. In the final product, where a high tensile modulus is due to a thermoplastic material (such as PVDF), at least some of the particles of the thermoplastic material can be in a coalesced or agglomerated form due to the heating and curing process. The agglomerated part of the particles can have different dimensions and can constitute part of the film.

[0115] The above techniques suitable for characterizing the dry coating of a fabric are known in the art.

[0116] According to an embodiment, the fabric is coated with 10g to 40g of dry coating per square meter of fabric, preferably 20g to 30g per square meter of fabric, more preferably 22g to 28g per square meter of fabric.

[0117] According to an embodiment, the coated fabric, i.e. the dry coating of the fabric, comprises 24% to 38% by weight of a material having a tensile modulus of at least 2000 MPa, 48% to 75% by weight of a binder, and 5.5% to 8.5% by weight of an antistatic agent. Preferably, the dry coating of the fabric comprises 28% to 34% by weight of a material having a tensile modulus of at least 2000 MPa, 55% to 70% by weight of a binder, and 6% to 8% by weight of an antistatic agent. More preferably, the dry coating of the fabric comprises 30% to 32% by weight of a material having a tensile modulus of at least 2000 MPa, 60% to 65% by weight of a binder, and 6% to 8% by weight of an antistatic agent.

[0118] For example, a fabric coating can include about 31% by weight PVDF, about 62% by weight binder, and about 7% by weight antistatic agent.

[0119] In an embodiment, advantageously, the coated fabric according to the invention has an impact and abrasion resistance of up to 8 seconds, measured according to EN 13595-2.

[0120] In an embodiment, advantageously, the coated fabric according to the invention has an impact and abrasion resistance of at least 3.5 seconds, preferably at least 4.5 seconds, more preferably at least 5.5 seconds, and even more preferably at most 8 seconds, measured according to EN13595-2.

[0121] According to an embodiment, the coated fabric according to the invention has impact and abrasion resistance at least 1.5 times and up to 10 times that of the fabric before coating.

[0122] As mentioned above, the coated fabrics of the invention, i.e. the dry or nearly dry coated fabrics according to the invention, are suitable for the manufacture of motorcycle wear, in particular motorcycle clothing such as trousers and jackets, which advantageously have an appearance that can also be used in everyday life.

[0123] As noted above, according to embodiments, the fabric may include one or more high tenacity high performance yarns, as well as one or more natural yarns and / or one or more synthetic yarns, and / or one or more blended yarns.

[0124] According to an embodiment, the fabric comprises at least 1% by weight, preferably at least 10% by weight, more preferably at least 25% by weight, even more preferably at least 50% by weight of high tenacity high performance yarns and / or fibers.

[0125] It is yet another object of the present invention to provide a garment comprising the coated fabric according to the present invention.

[0126] According to an advantageous embodiment of the invention, the composition of the invention is applied to the surface of the fabric that is visible when the article of clothing containing the coated fabric is worn.
