Description
Technical field
The invention belongs to infant article technical field, in particular to the high antibacterial of a kind of body surface, superabsorbent water, ventilative health
The dry and comfortable paper diaper of function.
Background technique
The core key technology of paper diaper is " core ".For technological layer, paper diaper core experienced three altogether so far
Secondary revolution: being the birth of disposable paper diaper before halfth century for the first time；It is that the eighties polymer absorbent material exists for the second time
Application on paper diaper is to be fully ensured the absorbent of product, and what market main brand generally used is the second generation
Core.But it is this kind of tradition core infiltration rate, anti-reverse osmosis degree, thickness and core in terms of there are still certain
The problems such as technology is limited to, and the red hip of baby, reverse osmosis side leakage are made still fails to improve solution., the application of paper diaper surface layer non-woven cloth
It is required that:
1, intensity wants height to be unlikely to deform, the non-woven cloth that do not slip through the net
2, good hydrophilic property, permeability are strong, reverse osmosis does not leak, and surface moment is dry and comfortable fastly
3, soft, not rubbing stimulates skin
4, nonirritant, sanitary index has to up to standard
In summary some, traditional paper diaper selection, in 20 grams or so of hot wind Nonwovens, is not had using grammes per square metre
Standby any antibacterial inhibits the healthcare functions such as bacterium, and the antibacterial concept product of Exemplary antibacterial is applied by surface layer and puts medicinal powder or a conception of species
Property blue chip, according to research firm work on marketing survey data show, as the inspection of paper diaper surface layer non-woven cloth as a result, nothing
An example product reaches the high antibacterial standard of CAS115-2005 healthcare function textile.And traditional handicraft chitin fiber non-woven fabrics
Do not have stronger hydrophily, do not have quickly absorb and reverse osmosis permeability, surface layer it is moister.Grammes per square metre is larger.National related sanitary
Index limited by technique be difficult it is up to standard.
Currently, the composite strengthening technology based on different webs is all being studied by strong company in the world, and has production
Product appear on the market.Wherein, it is the most noticeable be spinning fibre net or spun-bonded fibre net and carding fiber net composite consolidation.Currently,
Mainly have the absorbing material that spinning fibre net or spun-bonded fibre net and wood pulp cellulose net are carried out to spun lacing composite consolidation, as polypropylene fibre/
Wood pulp it is compound；Also the rag that spinning fibre net or spun-bonded fibre net and carding fiber net are carried out spun lacing composite consolidation cleans
Material and filtering material, as terylene/viscose glue is compound；There are also carry out spinning fibre net or spun-bonded fibre net and meltblown fiber web
The medical material of spun lacing composite consolidation, such as Hydroentangled SMS (spun-bonded/melt-blown/spunbond).These MULTILAYER COMPOSITE products
It will can be organically combined together the characteristics of each web, have become the important directions of non-woven cloth future development.
Patent of invention 201310087013.2 discloses a kind of pulp air-lay process and carries out the non-of composite consolidation with spunbond net
Woven cloths and its production technology.Two layers of spunbond net are compounded in by the invention using spun lacing technology with wherein pulp air-lay process is clipped in
Together, the water imbibition for not only having ensured finished product also improves the strength of composite non-weaving cloth.
Patent of invention 201310087077.2 discloses a kind of spinning fibre net and wood pulp paper composite non-weaving cloth and its life
Production. art.Two layers of spunbond net are combined with each other by the invention using spun lacing technology with wherein pulp paper is clipped in, by spunbond net
Between add wood pulp fiber layer, the water imbibition of finished product can be improved.
Patent of invention 200810230045.2 proposes compound non-of a kind of nylon or dacron carding networking and spunbond net and knits
Cloth and production method are made, upper layer is nylon or dacron carding networking, and lower layer is nylon or terylene spun-bonded method non-woven cloth, is passed through
Bilaminar fiber net is combined together by online or offline spun lacing reinforcing, can substitute existing common Hydroentangled product completely.
But existing technology be still difficult to prepare integrate light, thin, saturating, pro-skin is good, it is highly hygroscopic, be unlikely to deform
High-performance spinning fibre net or spun-bonded fibre net and other webs through spun lacing method it is compound prepared by non-woven cloth, such as with spinning
Web and carding fiber net carry out the grammes per square metre of the compound product of spun lacing generally all in 40 grams/m2More than.And currently on the market
Facial mask with non-woven cloth require light, thin, saturating, pro-skin is good, it is highly hygroscopic, be unlikely to deform, the basic 40 grams/m of grammes per square metre2Hereinafter, and paper
Urine pants plane materiel more requires grammes per square metre in 30 grams/m2Below.
Although spun-bond process production technology can 10 grams/m of industrialization production2Left and right Spunbonded Nonwovens, and have it is light,
Advantage thin, saturating and that strength is high, but since its fertile product of institute is only limitted to thermoplastic fibre, such as polypropylene fibre, terylene and brocade
Synthetic fibre etc., therefore its feel, the ability of absorption Essence and pro-skin sense are bad, are difficult to be directly used in facial mask.And comb networking method
Grammes per square metre can be made in 20 grams/m in the staple fiber of most of types, such as combing of cotton, silk, viscose glue and all kinds of chemical fibres2Fibre below
Tie up net.Seem.It can be by 10 grams/m2Left and right spinning building directly with 20 grams/m2Following carding fiber net progress spun lacing is compound to be added
Gu 30 grams/m can be prepared2Hereinafter, integrating light, thin, saturating, pro-skin is good, highly hygroscopic, the high-performance spun lacing that is unlikely to deform
Method joint product, but it is actually unworkable.Because in Conventional spunbond cloth, roll at fiber it is well-bonded, it is original
Fibre structure be entirely destroyed, be difficult spun lacing compound tense by these bonding points fiber hydrolization restore, due to this
The gross area of a little bonding points is larger, accounts for about 20% or so of non-woven cloth area, greatly consumes spun lacing efficiency, when spun lacing pressure
When power reaches 50bar, to staple card net belonged in press, but for spunbond net, due to the influence of bonding point, very big ground resistance
The interpenetrating and entanglement between filament web and web of staple fibers are hindered, product are caused to be layered.If hydraulic pressure is enlarged to 100bar
When, due to the connection and traction action of bonding point, cause the breadth of spunbond net significantly to shrink, grammes per square metre is caused to improve rapidly, leads to
Grammes per square metre can be often set to increase by 50% or so.
In order to reduce the influence of bonding point, attempt to by spinning fibre net directly with carding fiber net it is composite spunlaced plus
Gu it is desirably to obtain the joint product of good permeability, stable structure, but experiments have shown that, the spinning not Jing Guo consolidation process is fine
Net is tieed up, because losing the constraint of bonding point 6, along with the modulus of spinning fibre net common at present is larger, fiber is more thick and stiff,
It is easy to be broken up by spun lacing power, it can not be at cloth.In order to not break up web, the grammes per square metre of spun-bonded fibre net is only increased to 30
Gram/m2More than, to increase the saturation force of web, and the grammes per square metre of carding fiber net is also required in 20 grams/m simultaneously2More than.That is,
Total grammes per square metre of web is in 50 grams/m2When above, be possible to tangle under the action of spun lacing power into cloth.This kind of material is common to be done
Filtering material, grammes per square metre generally rest in 60 grams/m2Left and right.And facial mask and paper diaper plane materiel do not require nothing more than its nonwoven product must
Must there are good moisture absorption and moisture-inhibiting ability, it is necessary to which frivolous, grammes per square metre need to generally be controlled in 40 grams/m2Hereinafter, if can control
30 grams/m2It is more preferable below.As it can be seen that traditional spinning fibre net or spun-bonded fibre net and carding fiber net are simply answered
It closes, is difficult to produce 30 grams/m2Product below, it is difficult to meet light, thin, saturating requirement.Also it attempts to spinning fibre net
After carrying out saddening, then it is compound with carding fiber net, it, can be to refer to but have no to reduce the influence of spinning fibre net bonding point
Lead the mature technology scheme of production.Because only to being adjusted on hot rolling technology, without matching for fibre modification and water jet process
It closes, without complete theoretical direction, has any problem.Because bonding point is excessively firm, cause spun-bonded fibre net shrink or because
Bonding point is excessively weak, and fiber is thick and stiff, and web is caused to be broken up, and is very unstable to produce grammes per square metre in 40 grams/m2Following product.To the greatest extent
Spun-bonded fibre net (or spinning fibre net) and carding fiber net are carried out spun lacing composite consolidation and have become the exploitation paid close attention in the industry by pipe
Direction, but up to the present, there is not yet grammes per square metre is in 35 grams/m2Hereinafter, collection is light, thin, saturating, pro-skin is good, highly hygroscopic, not variable
Shape is in the spun lacing composite non-weaving cloth of one.
