Description

A kind of high antibacterial of body surface, ventilative, the dry and comfortable protection pad of refrigerant healthy functions
Technical field
The invention belongs to amenities technical field, in particular to the high antibacterial of a kind of body surface, ventilative, refrigerant healthy functions Dry and comfortable protection pad.
Background technique
When feminine halves possess sanitary napkin and menstrual period is made to become no longer embarrassed, people have invented similar with sanitary napkin principle Protection pad.The daily secretion except female menstrual period can be absorbed in it, dramatically reduces the worry of women.Protection pad generally compared with It is small relatively thin, it is a very useful invention to make one no sense of discomfort.Existing panty liner generally comprises hydrophilic layer, leads Fluid layer, dust-free paper and water suction macromolecule mixed layer, waterproof counterdie and strippable paper, hydrophilic layer are located at upper surface, and guide layer is set to parent Under water layer and it is located on dust-free paper and water suction macromolecule mixed layer, is waterproof under dust-free paper and water suction macromolecule mixed layer Counterdie, the strippable paper are connected to the bottom of the waterproof counterdie by adhesive sticker.Wherein hydrophilic layer is by one or more layers through parent The full-degradation lactic acid polymer spun-bonded continuous yarn non-woven fabrics of water process are constituted；Waterproof counterdie is by one or more layers full-biodegradable film It constitutes.Currently used protection pad surface layer can not play antibacterial, bacteria-eliminating efficacy substantially, and existing protection pad is in order to enhance absorption energy Power, what often can not be done is sufficiently thin, ventilative, refrigerant, the application requirement of protection pad surface layer non-woven cloth: intensity wants high not variable Shape, the non-woven cloth that do not slip through the net, good hydrophilic property, permeability are strong, reverse osmosis leaks, and surface moment is dry and comfortable, soft fastly, do not rub stimulation Skin, nonirritant, sanitary index have to up to standard.
In summary some, traditional protection pad selection, in 20 grams or so of hot wind Nonwovens, is not had using grammes per square metre 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 ways makes conceptual researches Blue chip, according to research firm work on marketing survey data show, as the non-woven cloth inspection of protection pad surface layer as a result, without an example Product reaches the high antibacterial standard of CAS115-2005 healthcare function textile.And traditional handicraft chitin fiber non-woven fabrics does not have Standby stronger hydrophily does not have and quickly absorbs and reverse osmosis permeability, surface layer are 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 protecting Pad 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 not require nothing more than its nonwoven product necessary for facial mask and protection pad plane materiel 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 Gram/m2It is more preferable below.As it can be seen that traditional spinning fibre net or spun-bonded fibre net are simply carried out with carding fiber net it is compound, It is difficult to produce 30 grams/m2Product below, it is difficult to meet light, thin, saturating requirement.Also it attempts to carry out spinning fibre net After saddening, then it is compound with carding fiber net, it, can be to instruct to give birth to but have no to reduce the influence of spinning fibre net bonding point The mature technology scheme of production.Because only, without the cooperation of fibre modification and water jet process, not having to being adjusted on hot rolling technology There is complete theoretical direction, has any problem.Because bonding point is excessively firm, spun-bonded fibre net is caused to shrink or because of bonding Put weak, 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.Although will Spun-bonded fibre net (or spinning fibre net) and carding fiber net carry out spun lacing composite consolidation and have become the developing way paid close attention in the industry, But up to the present, there is not yet grammes per square metre is in 35 grams/m2Hereinafter, collect light, thin, saturating, pro-skin is good, it is highly hygroscopic, be unlikely to deform in The spun lacing composite non-weaving cloth of one.

As shown in Figure 1, 2, 3, a kind of high antibacterial of body surface, ventilative, the dry and comfortable protection pad of refrigerant healthy functions, by skin-proximal Surface layer 4, the water absorption layer 5 set gradually downwards from surface layer 4, outermost ventilative leakproof film 6 and for fixing protection pad position Gum 7 forms, the surface layer 4 include by false bonded spunbond web 2 through it is online or offline at least one layer of carding fiber net 3 into Row spun lacing has middle layer made of reinforcing be entangled bonded layer 12, superficial layer is carded fiber layer 8, bottom surface layer is that false bonding is spun The Hydroentangled integrated non-weaving cloth base fabric 10 of viscous fibrous layer 9, the carding fiber net 3 by with it is hydrophilic include chitosan The staple card networking of fiber and mint fibers there is hydrophilic staple fiber can choose cotton fiber, silk fiber, viscose glue fine One or more of dimension, the vacation bonded spunbond web 2 is by the thermoplastic fibre after the processing of drop modulus and hydrophilic treated Hot rolling is reinforced after 11 filature fleece formation of long filament, the carded fiber layer 8 and skin attachement, false bonded spunbond fibrous layer 9 and suction Water layer 5 combines.2~5 layers are set as to improve comfort level and water imbibition, the carding fiber net.
The present invention under the premise of effective guarantee protection pad is ventilative, salubrious, adds peppermint by changing the traditional structure of protection pad The natural antibacterials fiber such as fiber and chitin fiber, so that antibacterial bacteriostatic is skin friendly, it is comfortable salubrious, it is fine using 2~5 layers of combing It ties up net 3 and false 2 spun lacing of bonded spunbond web is reinforced, changing conventional multilayer protection pad leads to the problem of its is blocked up, poor air permeability, And surface layer good hydrophilic property, it is easier to absorb, greatly reduces production cost, improve ventilative, antibacterial, salubrious effect.
The preparation of false bonded spunbond web 2 is one of key point of the invention, and false bonded spunbond web 2 refers to spinning When the bonding point 1 of viscous web is stretched power or impact force, bonding point 1 can be decomposed, and fiber will not be broken.Namely it is viscous Node 1 is less than the strength of fiber itself to cohesive force caused by fiber.The main points of web preparation, are to spinning fibre net When carrying out hot rolling, using low temperature, low pressure hot rolling, making to roll a fiber at place, there is no melt completely.Specifically, to polyester fiber Net, hot-rolled temperature should be controlled at 180~200 DEG C；To nylon fibre net, hot-rolled temperature should be controlled at 160~180 DEG C, right Polypropylene fiber net, hot-rolled temperature should be controlled at 80~110 DEG C, and hot rolling pressure is routine hot rolling pressure 0.9MPa~1.2 MPa 1/3~3/4.Drop modulus processing is the addition thermoplastic fibre spinning chips weight percent in thermoplastic fibre spinning chips For 0.1%~2% drop modulus master batch, hydrophilic treated is by impregnation method before 11 filature fleece formation of thermoplastic fibre long filament to heat The surface of Plasitc fibers long filament 11 uniformly attaches hydrophilic agent.
The fiber characteristics of false bonded spunbond web 1 are the webs for being added to drop modulus master batch and the preparation of hydrophilic master batch. It prepares main points, after total amount of adding is 0.5%~6% drop modulus master batch and hydrophilic master batch in spinning chips, through screw spinning Machine heating, mixing, metering, spinning, and stretching, sub-wire, lapping and formed or terylene or polyamide fibre or polypropylene fiber net.For It is convenient for production, it can also will drop modulus master batch and hydrophilic master batch is made into the modified master batch of unification.
The addition for dropping modulus master batch, is to drop low-fiber modulus, to improve deformation of fiber when by spun lacing power And entanglement capability, the fibre matting effect and efficiency when spun lacing composite consolidation are significantly improved, avoids web from being broken up, while can Improve the flexibility of product.Additive amount generally 0.1%~2%, can make the modulus of fiber reduce by 10%~20% or so, and make fiber Elongation at break improve 30% or so.For terylene, drop modulus master batch can be copolyesters, low molecular weight it is poly- to benzene two The polytrimethylene terephthalate and its their mixture of formic acid fourth diester, low molecular weight.For polyamide fibre, drop modulus is female Grain can be copolyamide, the polycaprolactam of low molecular weight, the poly- decamethylene diamine decanedioic acid of low molecular weight and its their mixing Object.For polypropylene fibre, drop modulus master batch can be different isotactic polypropylene, polyacrylate analog derivative, polyvinyl alcohol analog derivative, And its their mixture.
The addition of hydrophilic agent is the entanglement efficiency to improve fiber in spun lacing composite consolidation, while improving Compound Water The hydrophily of spunlaced nonwoven.Spun lacing efficiency 20%~30% can be improved, so that it is more abundant to tangle, Hydroentangled one is non-woven Cloth base fabric 10 is whole stronger.By being padded to spinning fibre net or spun-bonded fibre net, coating or sprinkling hydrophilic finiss Agent improves the hydrophily of web, and in spun lacing compound tense, most of hydrophilic agent can be all washed because of the effect of spun lacing power, The hydrophily and penetrating power of entangled bonded layer and false bonded spunbond fibrous layer in final products are lower, for protection pad just The menses reverse osmosis in water absorption layer can be prevented, the technique that traditional protection pad needs in addition to increase reverse osmosis layer is eliminated, reduces shield The production cost of pad so that protection pad is more frivolous, and due to using spun lacing mode, is knitted so that final Hydroentangled one is non- Bu Jibu is made with cell structure, considerably increases the gas permeability of protection pad.Therefore, thermoplastic fibre is carried out during the spinning process Impregnating hydrophilic agent is important step of the present invention.For terylene, hydrophilic agent can be polyester or polyethers containing hydrophilic radical Close object.For polyamide fibre, hydrophilic agent can be the copolyamide containing hydrophilic radical.For polypropylene fibre, hydrophilic agent, which can be, to be contained There is the derivative of polyacrylate or polyvinyl alcohol.Hot rolling bonds between forming the fiber of the false bonded spunbond web 1 Cohesive force caused by 6 pairs of fibers of point is less than the strength of thermoplastic fibre long filament itself.Thermoplastic fibre long filament, which can choose, to be washed One of synthetic fibre, polyamide fibre or polypropylene fibre.
