Definitions
- the present invention relates to a method for obtaining a fabric which has the special particularity in that the outer and inner faces thereof have different features, such that the inner face thereof is completely hydrophilic, while the outer face is completely liquid-repellent.
- a process in which a multi-layer fabric is obtained, involving an outer layer of a liquid-repellent fabric and an inner layer of a hydrophilic fabric, such that said two fabrics are sewn together forming a multi-layer structure.
- the present invention aims to simplify the process for obtaining a fabric with multiple properties, such as oleophobicity, hydrophilicity, elasticity, anti-wrinkle, antibacterial, quick drying, durability and stain-resistant, and all by means of a novel, more economical process.
- the method of the invention meets the technical challenges described above, allowing a single-layer fabric to be obtained with different properties on the inner and outer face thereof, specifically with hydrophilic properties on the inner face thereof and liquid-repellent properties on the outer face thereof, in addition to a series of additional features.
- the thread will have a section with multiple channels along the longitudinal section thereof. This shape of the cross section creates grooves on the surface that help manage moisture and make it easier for the fabric to dry quickly.
- the weaving process is carried out, making a double-faced circular knitted fabric: a "smoother" outer face, and an inner face with a three-dimensional "piqué"-type weave.
- the fabric is subjected to a thermosetting process at a specific width and temperature, thus giving it the "anti-wrinkle” property.
- the fabric is subjected to a process of applying an stain-resistant product, which, instead of being applied by bathing, is carried out by roller application, which allows said product to be applied on only one of the two faces of the fabric.
- this finish is thermoset at a specific temperature and for a specific time to ensure that the product remains on the fabric for a long time, despite washing or use.
- Figure 1 shows a block diagram of the different operational phases necessary for obtaining a single-layer fabric with different properties on both faces thereof, made in accordance with the object of the present invention.
- These threads include silver ions, present in all the material, both inside and outside the threads. In this way, an antibacterial effect is achieved, which remains, despite washing or the passage of time. This treatment, in turn, demonstrated that it has antiviral activity (95% of coronavirus is eliminated in 2 hours).
- Another feature of the thread is its section with multiple channels along the longitudinal section thereof. This shape of the cross section creates grooves on the surface that help manage moisture and make it easier for the fabric to dry quickly.
- the weaving phase (2) is then carried out, in which a double-faced circular knitted fabric is made, having a smoother outer face, and an inner face with a three-dimensional "piqué"-type weave.
- the fabric is then subjected to a first thermosetting process (3) at a specific width and at a temperature of 150°C for 1 minute and 10 seconds, and thanks to the type of material used (polyester) and the textile structure thereof, the fabric does not wrinkle.
- a first thermosetting process (3) at a specific width and at a temperature of 150°C for 1 minute and 10 seconds, and thanks to the type of material used (polyester) and the textile structure thereof, the fabric does not wrinkle.
- soft and flexible cross-linkable polyurethane fibres that have optimal features for obtaining fabrics with anti-wrinkle properties can be used.
- the fabric is manufactured, it is subjected to a washing process (4) (scouring), a dyeing process (5) and the application of a bathing process (6) (foulard-immersion) of a "hydrophilic" product, a product which, merely by means of example, is applied at a pressure of 3 bars with a fabric advance speed of 15 meters per minute.
- aliphatic polyurethane is applied in an aqueous solution that provides a soft and elastic touch with excellent behaviour to wet treatments.
- an anti-odour product can be applied.
- the fabric is very moisture-absorbent.
- an stain-resistant product is applied using a roller (7), this time not by bathing (foulard-immersion), which applies the stain-resistant product on one of the faces of the fabric, which will ultimately be the outer face thereof.
- This stain-resistant product consists of the joining of 3 components: an oleophobic and hydrophobic stain-repellent product, another product that fixes this stain-resistant product to the fabric, an isocyanate, and lastly a thickening product that gives the mixture of the 3 products a suitable viscosity so that it can spread well throughout the fabric, but prevents the product from penetrating the inside of the fabric.
- the hydrophobic product will materialise into a water-repellent product based on fluorocarbon or non-ionic perfluoro acrylate for synthetic and natural fibres and the mixtures thereof.
- a blocked isocyanate will be used for joint use with fluorocarbon resins that provide resistance to washing, and a thickener in inverse emulsion.
- the isocyanate is in a proportion of 20 g/l, the fluorocarbon in a proportion of 200 g/l and the thickener in a proportion of 10 g/l.
- thermosetting phase (8) is subjected to a second thermosetting phase (8) at a temperature of 150°C for one minute to ensure that the product remains on the fabric for a long time despite washing or use.
- a 100% recycled polyester-based fabric is obtained, in which a multifilament thread with silver ions made up of 47 micro-threads, a cross section with multiple channels along the longitudinal cross section thereof, with a smooth outer face and an inner face with a three-dimensional pattern, in which a hydrophilic product is embedded, and which, on the outer face thereof, incorporates a coating of a stain-resistant product.
