Definitions
- the invention relates to a process for manufacturing a fiber veil, the binder of which is derived from polyvinyl alcohol (PVOH) fibers.
- the veil produced according to the invention can in particular be used as a surface covering (“wall covering”). For this application, it can be glued to walls on one side using a water-based glue and receive a paint (with water or organic solvent) on the other side.
- veil is meant a veil made of completely dispersed filaments.
- a veil has a surface mass ranging from 10 to 60 g / m 2 and more particularly 20 to 40 g / m 2 , for example around 30 g / m 2 .
- the manufacture of a continuous veil involves the passage of a bed of dispersed filaments by a set of several successive devices each having to apply a specific treatment to said filaments.
- the fiber bed after its formation in a "formation device”, then passes through a "binder depositing device” then a “steaming device”.
- the transport of the bed through these devices is carried out using scrolling belts, and the bed is generally caused to pass from one carpet to another.
- the veil in formation tends to lose its cohesion, which results in structural defects of the final veil such as an irregular grammage.
- the continuous process according to the invention comprises: a step of dispersing cut filaments and staple fibers of PVOH in process water, then a step of forming a bed in a formation device by passage dispersion on a forming fabric through which the process water is drained, the filaments and fibers being retained on said fabric, then,
- the invention overcomes the above-mentioned problems.
- the PVOH fiber used at the outset acts as a binder for the web, it is not necessarily necessary to use a device for applying a binder, which implies that the sailing has fewer “carpet jumps” to perform.
- the Applicant has discovered that the PVOH fibers give solidity to the bed in formation, probably because the PVOH fiber gives tackiness to the various bed ingredients and maintains them. As a result, the bed is less damaged when the carpet is thrown.
- the filaments To be dispersed in water, the filaments must be able to remain in the individual state and not to combine mixed in the process water. If chopped strands, a set of filaments, are dispersed in water, these strands must be able to defilamentize in dispersion in water. “Yarn” is understood to mean a set of contiguous filaments and more particularly comprising from 10 to 2000 filaments. Thus, the filaments, more particularly those made of glass, can be introduced into the process water in the form of wires comprising more particularly 10 to 2000 filaments.
- the filaments which can be used in the context of the present invention generally comprise glass filaments and are more particularly glass filaments, which can be used during dispersion in the form of chopped strands.
- the filaments may have been sized during their manufacture, to be collected if necessary in the form of threads, in particular by sizing liquids comprising an organosilane and / or a tackifier ("film former" in English). In this case, it is preferable not to dry the filaments before dispersing them in water, so as to avoid sticking the filaments together, which would hinder their dispersion in the form of individual filaments.
- cut filaments in addition to glass filaments, it is also possible to use cellulose fibers (or “cellulose filaments” as a synonym) and / or polyester filaments, in particular polyethylene terephthalate (PET).
- cellulose fibers or “cellulose filaments” as a synonym
- polyester filaments in particular polyethylene terephthalate (PET).
- Cellulose fibers are generally obtained from wood pulp. This wood pulp is generally obtained from commercial sheets of cardboard which are softened with water. This water used to soften the cardboard is then used to transport the pulp to the installation for producing the dispersion. This water / pulp mixture generally contains just enough water to be able to transport the pulp by flow. This mixture pulp / water before reaching the middle of the dispersion generally contains from 70 to 99% by weight of water and 1 to 30% by weight of cellulose.
- the polyester filaments are generally cut and generally have a length ranging from 3 to 25 mm and have a diameter ranging from 7 to 20 ⁇ m. As polyester filaments which can be used, mention may be made of those sold under the reference EP133 by the company Kuraray.
- a mixture of glass filaments / cellulose fibers is used more particularly when good tear resistance is sought.
- a mixture of glass filaments / polyester filaments is more particularly used when good tear resistance and an improvement in the appearance of the haze are sought. Indeed, the polyester filaments give a more regular appearance to the veil.
- the PVOH fibers are discontinuous and generally have a length ranging from 3 to 15 mm and a diameter ranging from 7 to 20 ⁇ m.
- the cut filaments and the PVOH fibers are dispersed in water, for example in a pulper.
- the aqueous solution in which the cut filaments and PVOH fibers are dispersed is called process water.
- This dispersion can be carried out initially in a pulper for example with a proportion of filaments and fibers such that the sum of the mass of filaments + fibers ranges from 0.01% to 0.5% by weight of the sum the weight of the filaments, fibers and process water.
- the filament / fiber / process water mixture at the time of passing into the bed forming stage is such that the sum of the mass of filaments + fibers represents 0.01 to 0.5% by weight of said mixture and preferably 0.02 to 0.05% of said mixture.
- the mixture may undergo a decrease in the concentration of filaments + fibers when passing from the pulper to the device for forming the bed.
- an amount of PVOH fibers is used representing 1.5 to 20% by weight and more preferably 2.5 to 15% by weight of the sum of the mass of cut filaments and PVOH fibers.
- cut filaments only glass filaments can be used.
- cut filaments it is also possible to use a mixture of glass filaments and cellulose fibers, in particular in the following glass / cellulose mass ratio: from 99/1 to 80/20, and preferably from 95/5 to 90 / 10, it being understood that the mass of glass filaments takes into account its possible size.
- the process water may include a thickener to increase the viscosity of the process water.
- This thickener can be present in an amount of 0 to 0.5% by weight in the process water.
- This thickener can for example be a hydroxyethylcellulose (for example Natrosol 250HHR from Hercules).
- the process water may include a cationic dispersant.
- This cationic dispersant can be present in an amount of 0 to 0.1% by weight in the process water.
- This cationic dispersant can be, for example, guanidine or a fatty chain amine.
- the thickener is preferably introduced so that the process water has a viscosity of between 1 and 20 mPa.s at 20 ° C. and preferably between 5 and 12 mPa.s.
- process water / cut filaments is agitated, then sent to a permeable forming fabric (which can also be called a mat) letting the process water flow through it and retaining the cut filaments and the PVOH fibers at its area.
- Process water can be aspirated to improve its evacuation.
- Process water can be recycled to be mixed again with cut filaments and PVOH fibers.
- the forming fabric is a moving carpet, that is to say in movement, and conveying the bed in the direction of the steaming device.
- the final veil generally comprises 1.5 to 15% by weight of binder (which can be exclusively PVOH), and more generally 2.5 to 10% by weight of binder (which can be exclusively PVOH), the rest of the mass of the veil being generally constituted by the mass of the filaments which includes any sizing products which cover them.
- the veil according to the invention is generally based on glass filaments, that is to say it generally comprises at least 55% by weight of glass in the form of filaments.
- the veil may comprise at least 80% by weight of glass in the form of filaments, and this in particular when only glass filaments have been used as cut filaments. If the final veil comprises both glass filaments and cellulose fibers, these two types of components remain present in the final veil in the proportions of their introduction and which has already been said.
- the final veil comprises both glass filaments and polyester filaments, these two types of components remain present in the final veil in the proportions of their introduction and which has already been said. If one chooses to apply part of the total binder in the device for applying a binder, this is generally applied in the form of an aqueous dispersion
- the binder can be of the type usually used in this kind of embodiment.
- it may be plasticized polyvinyl acetate (PVAc) or acrylic styrene or self-crosslinkable acrylic or urea formaldehyde or melamine formaldehyde.
- PVAc plasticized polyvinyl acetate
- acrylic styrene acrylic styrene or self-crosslinkable acrylic or urea formaldehyde or melamine formaldehyde.
- the excess binder can be removed by suction through the forming fabric.
- the bed must enter wet (between 20 and 70% by weight of water, for example about 40% by weight of water) into the steaming device in order to allow the polyvinyl alcohol fiber to dissolve in the water .
- This dissolution occurs under the effect of temperature, generally from around 60 ° C.
- the PVOH fiber is thus transformed into binder droplets.
- the purpose of the heat treatment step is to evaporate the water as well as to carry out any chemical reactions between the various constituents such as, for example, condensations of -OH groups.
- the heat treatment can be carried out by heating between 140 and 250 ° C.
- the duration of the heat treatment generally ranges from 2 seconds to 3 minutes.
- the veil can be dried and heat treated in a hot air oven circulating through the carpet.
- At the end of the heat treatment essentially all the PVOH fibers are transformed into a PVOH binder and no longer appear in the form of fibers.
- FIG. 1 schematically represents a process for the continuous preparation of a veil according to the invention.
- the cut filaments and the PVOH fiber are dispersed in a pulper 1 in the presence of process water and with stirring.
- the mixture then optionally pours into a storage tank 2 through the pipe 3, the function of the storage tank being to increase the duration of mixing between the filaments and the process water.
- This storage bin is optional.
- the mixture is then brought through line 4 to line 5, which combines the flow of mixture from line 4 with a flow of recycled process water from the headbox 6 through line 7.
- A At this level, the content of filaments and fibers in the filament / fiber / process water mixture is greatly reduced.
- Process water is drained at 14 and possibly sucked at 15 through the forming fabric 8 and is recycled via the pipe 17.
- This recycled water is then shared at 16, for example for around 10% for return to the pulper through line 10 and for approximately 90% to return to the headbox 6 through lines 9, 7 then 5. Circulation in the lines is ensured by pumps 11, 12 and 13.
- the pump 11 is called the main pump ("fan pump" in English).
- the veil in formation 18 then makes a "carpet jump" towards the steaming device 19, and the final veil is wound at 20.
- the invention leads to a web having a very high level of tensile strength for low levels of binders, in particular such that the following relationship is verified:
- R ⁇ the tensile strength in daN for 5 cm
- L the rate of binder in the web in% by weight
- G the grammage of the web in g / m 2 .
- the tensile strengths of the veil according to the invention are twice that of a conventional veil bound by a formalin urea of very good characteristic (see in particular the examples).
- the veil according to the invention is more particularly intended for wall coverings.
- the veil according to the invention is therefore generally such that it does not contain PVC.
- the tensile strength was measured by the standard
- Glass strands cut to a length of 18 mm are used, said strands containing filaments with a diameter of 13 ⁇ m, said strands being coated with a size comprising an organosilane and having a moisture content of 13% by weight.
- These wires are used in the process of FIG. 1.
- the glass wires cut are introduced into the pulper so that their concentration therein is 1.95 (example 1), 1, 9 (example 2) , 1, 8 (example 3) grams per liter.
- fibers cut to 4 mm of PVOH are introduced into the pulper so that their concentration is respectively 0.05 (example 1), 0.1 (example 2), and 0.2 (example 3) grams per liter.
- the concentration of glass strands is then diluted by 10 and the concentration of filaments + fibers on arrival on the forming fabric was 0.2 g / l.
- the concentration of PVOH fibers on arrival on the forming fabric was 0.005, 0.01 and 0.02 g / l, respectively.
- the forming fabric was traveling at a speed of 80 m / min, the flow rate of glass fiber-PVOH fiber-process water mixture pouring onto the fabric being 35 m 3 / hour.
- the process water contained 0.1% by weight of hydroxyethyl cellulose (Natrosol 250HHR from Hercules) and 0.025% by weight of cationic dispersant (aerosol C61 from Cytec). After drainage and suction of excess water, the wet sheet contains 35% water. The sheet is then dried in a hot air oven at 180 ° C for 20 seconds. The veil obtained is very homogeneous and has a surface mass of 50 g / m 2 . It contains the quantities of PVOH indicated in Table 1. Table 1 collates the results.
- Example 1 The procedure is as for Example 1 except that no PVOH fiber is placed in the pulper, and except that a binder is added after the forming fabric and before drying by pouring out a cascade of a PVOH or urea formaldehyde solution on the moving web.
- the veils obtained all have a surface mass of 50 g / m 2 .
- Table 1 collates the results.
