Abstract

The present invention relates to a non-woven fabric manufacturing technique to solve the problem of continuously processing to obtain finished product. After reeling equipment, the non-woven fabric is fed into finished product processing equipment, including cutting to required size and form and binding edges by using hot melt adhesive, and finally the non-woven fabric can be made into the finished products such as sanitary towel, diaper, mattress and protecting pad, etc..

Description

Method for making non-woven fabric paper product

The present invention relates to the non-woven fabric paper manufacturing technology.

The manufacture method of Chinese patent application number 93118421.5 non-woven fabric papers, be to utilize the bridging action between chemical fibre and fiber two compositions to merge, not only can utilize and reclaim the paper fiber and save chemical fibre raw material, pollution-free in the moulding, one has available invention on the industry really, right its non-woven fabric paper of making is a kind of raw material or semi-finished product, desire utilizes it to be made for finished product, use mattress as diaper cotton wool or puerpera, patient, then must further process again, not only time-consuming, and the increase expense.

The objective of the invention is further to improve, a kind of method for making non-woven fabric paper product that can no longer carry out following process is provided at the problems referred to above that foregoing invention exists.

The object of the present invention is achieved like this: method for making non-woven fabric paper product, and it is that chemical fibre and two kinds of compositions of paper fiber of constituting Nonwovens are smashed to pieces respectively in advance; Send in the mixer and mix; Send in the centrifugal device of a make-up machine again and make chemical fibre and two kinds of compositions of paper fiber of mixing present afloat, its centrifugal force of mat is got this mixture on a conveyer belt that is arranged under this centrifugal device again; Make through an air intake device again that this mixture is smooth to form a Nonwovens film in conveyor belt surface; This Nonwovens film enters a plurality of make-up machines of establishing in addition and applies all the other machined layer layer by layer on this Nonwovens film after going out make-up machine; Again above-mentioned machined object is sent into heating generation bridge formation effect in the heating furnace; After this process,, again it is applied the hydrophobic layer film through drum apparatus; And then after a calender is rolled over hot compacting; The mat roll device arrangement of being reeled again, it is characterized in that: after roll device, again its input finished product processing unit (plant) is processed, in the finished product process, comprise it is planted and be cut into required shape size, edge, make the finished product of cotton wool, diaper, mattress and protection pad and so at last with following process such as hot melt adhesive is bonding.

Above-mentioned manufacture method directly is processed into finished product with non-woven fabric paper, can reach cost and economize the efficient height; Can simplify procedure of processing, manufacture is simple; Do not use adhesive bond, avoid polluting; Roll the mode of knitting than traditional intersecting with fine needle, equipment is simple, and cost falls in easy-maintaining; With chemical fibre and two kinds of compositions of stationery is the non-woven fabric paper material, can save chemical fibre, reclaims the paper fibre, reduces cost; Its use " high molecular polymer " or " the cotton layer of SOFEX " etc. have the bar water layer of height water imbibition material, the bridge formation of mat chemical fibre and paper fiber is done, can consolidate bar water layer structure, it is unlikely because of rupturing behind the absorption liquid or forming piece, can improve user's comfortableness.

Be described further again below by drawings and Examples.

Fig. 4, diaper finished product stereoscopic schematic diagram of the present invention;

Fig. 5,6 mattresses of the present invention, protection pad finished product stereoscopic schematic diagram.

As shown in Figure 1: method for making non-woven fabric paper product roughly is: chemical fibre is opened fine A1, waste paper is smashed A2 to pieces---sends into A3 in the make-up machine after mixing and---gets in A4 on the conveyer belt with the centrifugal device of make-up machine and---apply other machined layer A8, A9 with make-up machine and---heat A6---apply hydrophobic layer A51---with the calender embossing or flatten A62---after being sent by drum apparatus in heating furnace, with roll device arrangement A7---finished product processing unit (plant) A10---the finished product A100 that reels in mixer.

As shown in Figure 2: by semi-finished product section of the present invention as seen: it is folded mutually layer by layer to fail to see cloth film 5 macromolecule water uptake layers 81, hydrophobic layer film 51, and in each interlayer the papery interlayer 52 with gas permeability and water permeability is arranged again.

As shown in Figure 3: in conjunction with consulting Fig. 1, its technological process combined process equipment roughly is: the chemical fibre that will constitute non-woven fabric paper and new two kinds of compositions of paper pulp are sent into respectively in chemical fibre bruisher 1 and the paper fiber bruisher 2 and are smashed to pieces, in of the outlet of this chemical fibre bruisher 1 with paper fiber bruisher 2, be provided with a mixer 3, be provided with an air exhauster 32 in the porch of mixer 3, mix in chemical fibre after mat air exhauster 32 will be smashed to pieces and the paper fiber suction mixer, then utilize an air exhauster 31 that is arranged at mixer 3 outlets that the mixture that mixes is sent in the centrifugal device 41 set in the make-up machine 4 again, this centrifugal device 41 can make the chemical fibre that mixes and two kinds of compositions of paper fiber of sending into present an afloat, the centrifugal force that produced of this centrifugal device 41 of mat is got this mixture on a conveyer belt 42 that is arranged under this centrifugal device 41 again, have an air intake device 43 in conveyer belt 42, can guarantee this mixture smooth in this conveyer belt 42 the surface and form a Nonwovens film 5, that is the non-woven fabric paper of pre-profiling, behind make-up machine 4, be provided with multi-section make-up machine 8 in addition, 9, this make-up machine 8, be provided with raw material in 9 with make-up machine 4 identical materials, when Nonwovens film 5 by the time can increase its thickness and intensity, if make-up

machine

8,9 set raw materials are different with make-up machine 4, as apply the machined layer of hydrophilic layer via make-up machine 8, it is macromolecule water uptake layer 81, so-called hydrophilic layer, can be " high molecular polymer " that generally be commonly called as or " the cotton layer of SOFTEX " waits and has highly water-absorbing material, the setting of right make-up machine quantity is not limited to two of Fig. 3, changeable, mat conveyer belt 42 Nonwovens film 5 mats one suction means 44 that will execute machined layer such as hydrophilic layer is up drawn and is transferred in the heating furnace 5 to produce through heating and adds the bridge effect again, when chemical fibre and paper fiber generation bridging action while, the structure of macromolecule water uptake layer 81 is combination with it simultaneously also, so can strengthen its connectivity, fracture or one-tenth piece behind the unlikely absorption liquid, after sending by heating furnace 6 again, earlier make preliminary seamless through a drum apparatus 61, then apply hydrophobic layer film 51 again, so-called hydrophobic layer can be PE, PP, PET etc. have the material of water proofing property, therefore can constitute cotton wool or diaper etc., and the scope of application can be extended to the puerpera, patient's mattress, protection pad.Above-mentioned processing gained semi-finished product are again in a calender 62 of drum apparatus 61 outlet peripheral hardwares, rolled over hot compacting according to institute's requirement condition continually after, with roll device 7 arrangement of reeling, send into finished product processing unit (plant) 10 then and be processed into required finished product again.

Shown in Fig. 4～5: this shows the stereoscopic of three kinds of finished products that the present invention makes, it is letter totally.
