Definitions
- the present invention relates to machines for producing woven, knitted and non-woven textile products by the technique known as "jets of water” under pressure.
- US Pat. Nos. 3,214,819, 3,508,308 and 4,190,695 disclose a process for the production of nonwoven textile webs in which the cohesion and interlacing of the elementary fibers together are obtained by the action of a plurality of jets of high-pressure water passing through a web or a sail moving on a perforated support.
- perforated rotary drums are generally thick and rigid metal tubes drilled with cylindrical or conical holes. These drums are not directly in contact with textile materials because their openings are too large. They are in particular covered by perforated supports of small holes such as metal or plastic fabrics.
- the invention overcomes these disadvantages by a particular design of the surface of the perforated rotary drum.
- the drum according to the invention can receive any type of metal or plastic fabrics, thin micro perforated metal sleeves, metal sleeves whose surface has been previously embossed as well as plastic sleeves etched by laser.
- the drum according to the invention offers an excellent and uniform drainage of the water coming from the jets of water, appreciably improves the quality of the nonwovens produced, without causing the attachment of textile materials such as fibers and other constituents of the textile products and this whatever the water pressures used for the water jets.
- the drum according to the invention also allows easy disassembly of the outer sleeves without damage.
- Nonwovens produced with a drum according to the invention are free of marks or impression of the drum regardless of the pressure of the jets.
- the invention relates to a drum whose external lateral surface is provided with perforations separated by solid parts, characterized by recessed portions which are machined in the solid parts at the outer lateral surface.
- the recessed portions can be easily obtained by machining.
- the recessed portions of the lateral surface are obtained by machining the already cylindrical blank of the drum. Machining is in fact a cheap technique for producing recessed portions, stripes or recesses according to the preferred dimensions. The machining also allows to obtain an excellent precision on the dimensions and to weaken as much as possible the solid parts.
- the ratio of the area of the perforations to the total area of the outer lateral surface is between 30% and 90%, but preferably it is between 60 and 80%, which greatly reduces the twists of the jet.
- the thickness of the side wall of the drum is preferably between 1 mm and 60 mm and better still between 5 mm and 40 mm.
- the perforations have a diameter of between 3 and 20 mm.
- the thickness of the recessed portions is preferably between 0.25 mm and 5 mm and better still between 0.5 mm and 2 mm and their width between 0.6 and 20 mm.
- the length of a non-recessed portion is from 30 to 100% of the diameter of a perforation and the width is from 0.6 to 4 mm, preferably 2 mm.
- the ratio of the area of the recessed portions to the surface of the solid portions is greater than 70 and from
- the drum is preferably made of bronze or stainless steel and has an outside diameter of between 200 mm and 1200 mm.
- the perforations are preferably cylindrical or conical, their circular cross section greatly facilitating the manufacture of the drum.
- the water jets have a diameter of 50 to 250 microns and the pressure of the water preferably from 10 to 500 bar.
- a recessed portion leading to two adjacent perforations is on the line passing through the centers of these two perforations and, better still, there are only two parts. hollowed out leading to each perforation.
- the recessed parts are interrupted by the perforations. At diametrically opposite points of each perforation leave two recessed portions. The diameters just discussed, if they are not aligned, are parallel from one pair of perforations to another.
- the invention also relates to a machine for entanglement by water jets of a nonwoven, comprising a drum, means for driving the drum in rotation, a sleeve provided with openings, threaded onto the drum and an injector system arranged so as to project jets of water on the outer lateral surface of the sleeve, characterized in that the drum is as defined according to the invention.
- the particularly cylindrical openings have a larger dimension of between 30 and 800 ⁇ m and the sleeve has a thickness of between 0.10 mm and 3 mm.
- the ratio of the area of the openings of the sleeve to the total area of its external lateral surface is preferably between 5% and 50%.
- FIG. 1 is a diagrammatic perspective view of an entanglement machine of a water-jet nonwoven according to the invention
- FIG. 2 is a partial view of section of the part surrounded by a circle in Figure 1
- Figure 3 is a view similar to Figure 2 of a variant.
- Figures 4 and 5 are partial developed views of two embodiments.
- the machine represented in FIG. 1 comprises a fixed and hollow body 1 which is pierced with slots facing injectors 2 and 3 capable of sending jets of water of a diameter of 150 microns under a pressure of 250 bar.
- the body 1 is surrounded by a perforated drum 4 which is rotated about its axis by a motor 5 with the aid of a driving device 6.
- the drum 4 is surrounded by a perforated sleeve 7 openwork of 200 microns in diameter, which may be a fabric, a thin microperforated metal envelope, an embossed sleeve, a sleeve of plastic material etched by laser.
- the injectors 2, 3 are arranged to project the jets of water on the outer lateral surface of the sleeve.
- the drum 4 has non-recessed portions 8 or intact which are derived from the outer lateral surface and the recessed portions 9 machined in the surface of the drum 4 which is directed towards the sleeve 7.
- the portions 8 delimit perforations 10 cylindrical through.
- the free ends of the parts 8 are in contact with the inner face of the sleeve 7.
- the drum comprises non-recessed portions 11 and recesses 12, the tips 13 of the non-recessed portions pointing towards the sleeve 7 are in contact with the inner side of it.
- the perforations 10 are arranged in rows of helices.
- the diameter D of the perforations 10 is 10 mm.
- the length L of the non-recessed portions is about 4 mm.
- the width of the recessed portions 9 is 2 mm. All the hollow parts 9 open on the perforations.
- the entire outer face of the drum is the same surface with the exception of the recessed portions 9 which are recessed.
- FIG. 5 What essentially distinguishes the embodiment of FIG. 5 from that of FIG. 4 is that there are only two non-recessed portions 8 of the solid portions that touch each perforation and that an unenclosed portion 8 that touches at its ends two adjacent perforations is on the line passing through the centers of these two perforations 10.
- the angle X of the line of these centers with a generatrix, parallel to the axis of the drum, is between 0 and 180 °. It is 90 ° in FIG. 4.
- the two non-recessed portions 8 which touch the same perforation do so at diametrically opposite points.
- the width of the recessed portions 9 is 8 mm.
