The specific embodiment
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Air-lay web hydro-entangled composite entanglement product, has double-layer structure at least, wherein having one deck at least is Time of Fluff Slurry superbhort fiber net after pulp is discongested, and having one deck at least is non-woven web of staple fibers, and the fiber of described Time of Fluff Slurry superbhort fiber net and non-woven web of staple fibers twines obvolvent mutually.The grammes per square metre of this hydro-entangled composite entanglement product is at 30-100g/m
2Wherein the content of superbhort fiber Time of Fluff Slurry is 10-70%, and superbhort fiber length is 1.0-2.5mm, non-woven short fibre content 30-90%.
Referring to Fig. 1, a kind ofly make the method that said flow becomes the net hydro-entangled composite entanglement product, comprise the steps:
1, by dry method paper forming device by air-laying moulding Time of Fluff Slurry superbhort fiber net; Its moulding Time of Fluff Slurry superbhort fiber net has two kinds of methods, a kind of method is online into the net, concrete steps are after the fine hair pulp is discongested through machinery, fully discongested and be separated into single Time of Fluff Slurry superbhort fiber, send into continuously with blower fan in the former of pulp air forming equipment, after in former, evenly disperseing, by the effect of vacuum draw, be dispersed on the mobile moulding guipure, form Time of Fluff Slurry superbhort fiber net.
Another kind method is after the fine hair pulp is discongested through machinery, fully discongested and be separated into single Time of Fluff Slurry superbhort fiber, send into continuously with blower fan in the former of pulp air forming equipment, after in former, evenly disperseing, by the effect of vacuum draw, be dispersed on the mobile moulding guipure, form Time of Fluff Slurry superbhort fiber net, form Time of Fluff Slurry superbhort fiber net volume material by batching again, use volume to put equipment and deliver on the recombination line.
2, the non-woven web of staple fibers of moulding; Non-woven web of staple fibers can become a kind of one-tenth net mode in the net to carry out online one-tenth net by carding, air lay, filature fleece formation, spray fusing.Also can pass through the pre-XianCheng of a kind of one-tenth net mode net in carding, air lay, filature fleece formation, the spray fusing one-tenth net, and form the coiled material of non-woven web of staple fibers, put equipment by volume and deliver on the recombination line.
The shaping guipure that non-woven web of staple fibers and Time of Fluff Slurry superbhort fiber net move in forming process can adopt the guipure of independent operating separately, also can use same guipure.The fiber web of moulding on guipure, or to be used for compound fiber web coiled material be with the moving of guipure, and during through the back segment process, is superimposed on together.
Before compound, can onlinely in advance carry out the water thorn and handle non-woven web of staple fibers tow sides.Can certainly directly use through water and sting pretreated coiled material.After the water thorn was handled, Time of Fluff Slurry superbhort fiber net thereafter can be when non-woven web of staple fibers moves, and stack just can be carried out the water thorn of following step and handle thereon after the stack.
3, Time of Fluff Slurry superbhort fiber net and non-woven web of staple fibers are covered through vertically superposeing completely, and make composite fiber web continuously export water thorn equipment to;
4, the High-Pressure Water of water thorn equipment generation makes the mutual winding obvolvent between the fiber to the impact of composite fiber web, forms a kind of composite fibre web frame with certain intensity; Before the water thorn, can carry out pre-wet process, to increase the effect of water thorn to composite fiber web.
During the water thorn, the High-Pressure Water that water jet produces impacts composite fiber web, makes to twine obvolvent between the fiber mutually, forms a kind of composite fibre web frame with certain intensity.During the water thorn, the liquid drugs injection bore dia 0.08-0.18mm of water jet, hole density is 10-24 hole/cm; Hydraulic pressure 30-150 * 10
5Pa, quantity of circulating water 50-200m
3/ h.Because tiny fiber can enter water circulation system, in constantly circulating, can stop up pin hole.Therefore recirculated water will carry out necessary purification and filtration, in time gets rid of the fiber fines that is blended in the recirculated water.
Water thorn process can be carried out Hydroentangled processing to composite fiber web different layer or face.
5, after the water thorn, contain a large amount of moisture in the composite fiber web product, dewater by vacuum draw;
6, after the vacuum draw dehydration, enter heated-air drying.The dry penetration heated-air drying that adopts can be selected drying box, also can select the dry cylinder of drum-type.According to the quantitative and moisture of product, and speed of production, dry temperature is at 120-200 ℃.The hot blast impingement drying helps keeping the gas permeability of product, bulkiness, and high temperature drying still is the process of product approval simultaneously.
7, will through dried composite fiber web put in order with batch after become air-lay web hydro-entangled composite entanglement product.
Referring to Fig. 2, the air-lay web hydro-entangled composite entanglement product manufacturing equipment comprises frame and is installed on the frame, along non-woven web of staple fibers web-forming equipment 1, water thorn equipment 2, dehydration equipment 3, Time of Fluff Slurry superbhort fiber net web-forming equipment 4, non-woven web of staple fibers web-forming equipment 1a, water thorn equipment 2a, dehydration equipment 3a, drying box 5, the dry cylinder 6 of drum-type, the taking-up equipment 7 of direction of advance.
Non-woven web of staple fibers web-forming equipment 1 is that a volume is put equipment 11 and a mobile guipure 12, and volume is put equipment 11 13 volumes of the preformed non-woven web of staple fibers on it are placed on the mobile guipure 12.Certain non-woven web of staple fibers web-forming equipment 1 can also become a kind of and mobile guipure 12 in the net for carding, air lay, filature fleece formation, spray fusing, the moulding on the guipure that moves of non-woven web of staple fibers 13.Non-woven web of staple fibers web-forming equipment also can also comprise shredding equipment, mixing device, refueling water equipment, carding equipment and the lapping equipment of fiber at least.
Carry out the processing of water thorn by the non-woven web of staple fibers 13 that the guipure 12 that moves moves by water thorn equipment 2, the non-woven web of staple fibers 13 after the water thorn is handled is sent into dehydration equipment 3 and is dewatered.
