Definitions
- the present invention is related to the techniques for manufacturing sheet materials, and more particularly it is related to sheet materials with incorporated microspheres to modify their properties and with a process for obtaining them.
- the temperature of a car cabin can exceed 80 ° C in a hot summer during the day due to incident solar radiation while in a winter temperatures can reach ⁇ «30 ° C. Under these conditions, passengers may experience the bad experience of bringing their body contact into contact with the heating or cooling shock of a seat, steering wheel or interior that can reach even higher temperatures. This is of great importance in the case of automobiles because a passenger, when in a vehicle, puts in contact with any of these elements 15 to 20% of the surface of the skin of his body.
- air conditioning systems can dampen this effect, the time required to level the temperature of such objects is insufficient for the passenger to feel adequate comfort for long periods of time, even in those seats that have ventilation or thermal control since in addition, the heat transfer by conduction of the body due to contact with the seat that is initially very cold or very hot plays an important influence on the thermal sensation of the passenger of a car.
- the use of air conditioning has been used, however its use translates into significant consumption from the economic and energy point of view, in addition to not being completely efficient, by virtue that the air conditioning systems do not have this purpose of cooling down the internal components of the car.
- smell has always been considered the lowest of the senses, which can be dispensed more quietly because it alters our perception to a lesser extent than ista or touch. However, without smell we would be deprived of certain emotions.
- interiors which incorporate lamellar materials, whether natural or synthetic, such as leather and its by-products such as carnaza, polymeric synthetic materials, or fabrics of various natures.
- lamellar materials whether natural or synthetic, such as leather and its by-products such as carnaza, polymeric synthetic materials, or fabrics of various natures.
- the interiors must comply with specifications of resistance to use, confer comfort and safety to the user.
- thermal control aids such as microspheres of phase change materials (paraffins, hydrated salts or others) optimally perform their regulatory function.
- thermal comfort characteristics on substrates without surface finish, including scab leathers.
- Japanese Patent No. 20011234200 is found that protects a method for the manufacture of scented skin by granting sufficient aroma for a relatively long period of time.
- the skin pbtihe its characteristics after being covered with a spray containing microspheres with an aroma.
- Japanese Patent No. 04202483 describes a coating composition that allows it to maintain its aromatic properties, said composition contains microencapsulated perfume containing a UV absorber or a light stabilizer in amounts ranging from 0.1 to 10% bp, or in relation to the perfume, RO ⁇ at least one member selected from phenol, ketone and aldehyde groups in 5% or less and where the main ingredient is a melanjna resin.
- Chinese Patent 1306094 protects a process for obtaining scented skin that consists in immersing the skin in a perfume solution, having advantages such as: uniform distribution and a durable fragrance.
- Figure 1 is a cross-sectional view of crusted leather, showing a matrix of fibers and inadequate penetration of microspheres.
- Figure 2 is a cross-sectional view of crusted leather, showing a matrix of fibers and adequate penetration of microspheres.
- Figure 3 is a graph in which the encapsulated and non-encapsulated essence release intensities are compared in relation to time, for the leathers of Example 2 of the present invention.
- microspheres with properties modifying agents incorporated during the wet and dry treatment and finishing of sheet materials it is possible to obtain laminar materials with various colors and modify their properties, such as thermal regulation properties, perfume release or pleasant aromas and resistance to microorganisms, among many others, by incorporating microspheres with modifying agents of suitable properties for the intended purpose. These characteristics make the sheet material suitable for application in the automotive industry, in furniture and other household items or in clothing, among other applications.
- the sheet materials with incorporated microspheres of the present invention comprise: a matrix of fibers; and at least from about 0.5% to about 16% by weight, on the basis of weight of the fiber matrix, of microspheres that with properties modifying agents, either incorporated within said fiber matrix, or, applied on at least one of the surfaces of the sheet material.
- the microspheres contained in the sheet materials of the present invention contain properties modifying agents, which are selected from agents such as: temperature regulating agents, aromas, perfumes, biocides and mixtures or combinations thereof.
- the sheet materials are selected from sheet materials consisting of natural or synthetic fibers, more preferably being selected from fabrics of natural fibers or synthetic, leather, leather products, polymeric sheet materials and mixtures or combinations thereof.
- the temperature regulating agents have a melting point comprised between -10 ° C and 70 ° C, and more preferably cbn 10 to 30 atoms of linear paraffins are selected from carbon.
- the paraffins are selected from n-tridecan, n-hexadecane, n-heptadeGano, n-octadecanp, n-nonadecane, n-eicosano, n-heneicosano, n-docosano, n-tricosano, n-tetracosano, n- ⁇ peptacosano, n-hexacosano, n-heptacosano and n-octacosáno.
- the property modifying agents achieve a greater permanence of the effect of the property modified by an effect of prolonged release of such agents, as is the case with perfumes, aromas and biocides.
- the process consists of a contact mixing stage, which consists in contacting a sheet material constituted by a matrix of fibers with a microsphere suspension. containing a surfactant additive a drying stage for drying the sheet material so that the microspheres are uniformly incorporated into the fiber matrix of the sheet material and a finishing stage where a coating is applied on the sheet material, preferably Exterior.
- a coating that also includes the suspension of properties modifying microspheres containing a surfactant additive on at least one of the surfaces of the sheet material, to finally dry the sheet material so that the ⁇ microspheres are also included in at least one of the surfaces thereof.
- the procedure is performed from any type of leather or derivatives thereof, that is, from any material derived from the skin or skin of an animal, which has already been subjected to at least one tanning process, the leather being also contacted with a greasing agent and other additives, working or tanning known in the state of the art, preferably at the same time as the suspension of microspheres
- the greasing agent can be contacted with the leather or its derivatives at an additional stage, either before or after the incorporation of the microsphere suspension.
- this is done slowly in a tank including stirring means in the presence of water at a temperature and about 5 o C to about 80 9 C.
- the surfactant additive comprises from 10 to 35% fatty alcohols; from 30% to 80% fatty acids; 30% to 80% sorbitan esters; and, from 1 to 10% of fatty amines and ethoxylated derivatives of fatty alcohols, fatty acids and sorbitan esters.
- the fatty alcohols are selected from isodecyl alcohol, lauric alcohol, tridecyl alcohol, cetyl alcohol, ketostearyl alcohol, stearyl alcohol, oleic alcohol and mixtures or combinations thereof.
- fatty acids are preferably selected from lauric acid, palmitic acid, polyethylene glycol monosterate, stearic acid and oleic acid.
- Figure 2 shows a cross-sectional view of crusted leather having suitably incorporated microspheres 20 that modify the properties in accordance with the present invention both in the fiber matrix and in the finish shown in the flower side 40.
