Description

The dry and comfortable protective pad of healthy functions that a kind of body surface height is antibacterial, ventilative, refrigerant
Technical field
The invention belongs to hygienic article technical field, the dry and comfortable protective pad of healthy functions that particularly a kind of body surface height is antibacterial, ventilative, refrigerant.
Background technology
When feminine halves have sanitary towel and make to become menstrual period no longer embarrassed, people have invented the protective pad similar with sanitary towel principle.It can absorb the daily secretions outside female menstrual period, dramatically reduces the worry of women.Protective pad is general less thinner, thus makes people not have sense of discomfort, is a very useful invention.Existing sanitary pad generally comprises hydrophilic layer, guide layer, dust-free paper and water suction macromolecule mixed layer, waterproof counterdie and strippable paper, hydrophilic layer is positioned at upper surface, guide layer to be located under hydrophilic layer and to be positioned on dust-free paper and water suction macromolecule mixed layer, be waterproof counterdie under dust-free paper and water suction macromolecule mixed layer, described strippable paper is connected to the bottom of described waterproof counterdie by adhesive sticker.Wherein hydrophilic layer is made up of one or more layers full-degradation lactic acid polymer spun-bonded continuous yarn non-woven fabrics through hydrophilic treated; Waterproof counterdie is made up of one or more layers full-biodegradable film.Antibacterial, bacteria-eliminating efficacy can not be played substantially in protective pad top layer conventional at present, and existing protective pad is in order to strengthen absorbability, that often can not do is enough thin, ventilative, refrigerant, the application of protective pad top layer non-weaving cloth requires: intensity wants height not yielding, the non-weaving cloth of not slipping through the net, good hydrophilic property, permeability by force, not reverse osmosis leak, surface moment soon dry and comfortable, soft, the chafe that do not rub, nonirritant, sanitary index must be up to standard.
Comprehensive what time above, tradition protective pad choice for use grammes per square metre is at the hot blast Nonwovens of about 20 grams, do not possess the health cares such as any antibacterial or anti-bacteria, the antibacterial concept product of Exemplary antibacterial is coated with by top layer and puts medicated powder or a kind of conceptual blue chip, according to research firm's marketing survey data display, as protective pad top layer non-weaving cloth censorship result, none routine product reaches CAS115-2005 health care textile height antibacterial standard.And traditional handicraft chitin fiber non-woven fabrics does not possess stronger hydrophilic, does not possess absorption and reverse osmosis permeability fast, and top layer is moister.Grammes per square metre is larger.Country's related sanitary index is difficult to up to standard by technique restriction.
At present, company strong in the world is all being studied based on the fibroreticulate composite strengthening technology of difference, and existing procucts appear on the market.Wherein, the most noticeable is the composite consolidation of spinning fibre net or spun-bonded fibre net and carding fiber net.At present, mainly contain spinning fibre net or spun-bonded fibre net and wood pulp cellulose net are carried out the absorbing material that water stings composite consolidation, as the compound of polypropylene/wood pulp; Also have and spinning fibre net or spun-bonded fibre net and carding fiber net are carried out rag cleaning material and the filtering material that water stings composite consolidation, as the compound of terylene/viscose glue; Also have and spinning fibre net or spun-bonded fibre net and meltblown fiber web are carried out the medical material that water stings composite consolidation, as Hydroentangled SMS (spun-bonded/melt-blown/spunbond) etc.Each fibroreticulate feature can organically combine by these MULTILAYER COMPOSITE products, has become the important directions of non-weaving cloth future development.
Patent of invention 201310087013.2 discloses non-weaving cloth and the production technology thereof that a kind of pulp air-lay process and spunbond net carry out composite consolidation.This invention utilize water thorn technology by two layers of spunbond net be clipped in wherein pulp air-lay process and be combined with each other, not only ensured the water absorption of finished product, also improved the brute force 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 production technology thereof.This invention utilize water thorn technology by two layers of spunbond net be clipped in wherein pulp paper and be combined with each other, by adding wood pulp fiber layer between spunbond net, the water absorption of finished product can be improved.
Patent of invention 200810230045.2 proposes non-weaving cloth and the production method that a kind of nylon or dacron carding become net and spunbond net compound, its upper strata is that nylon or dacron carding become net, lower floor is nylon or terylene spun-bonded method non-weaving cloth, admittedly bilaminar fiber anastomose is combined by online or off-line water CIJIA, existing common Hydroentangled product can be substituted completely.
But, existing technology is still difficult to prepare that collection is light, thin, saturating, good, the high moisture absorption of pro-skin, the high-performance spinning fibre net being not easily deformed in one or spun-bonded fibre net and other fleeces through water acupuncture manipulation compound obtained non-weaving cloth, all at 40 grams/m the grammes per square metre of stinging the product of compound as carried out water with spinning fibre net and carding fiber net 2above.And facial film non-weaving cloth in the market all requires good, the high moisture absorption of light, thin, saturating, pro-skin, not yielding, the basic 40 grams/m of grammes per square metre 2below, and protective pad plane materiel more requires that grammes per square metre is at 30 grams/m 2below.
Although spun-bond process production technology industrialization can produce 10 grams/m 2left and right Spunbonded Nonwovens, and there is light, thin, saturating and that brute force is high advantage, but be only limitted to thermoplastic fibre, as polypropylene, terylene and chinlon etc. due to its fertile product, therefore its feel, the ability of adsorbing essence and pro-skin sense are all not good, are difficult to be directly used in facial film.And carding method can by the short fiber of most of kind, as cotton, silk, viscose glue and all kinds of chemical fibre combing make grammes per square metre at 20 grams/m 2following fleece.Seem.Can by 10 grams/m 2the spinning building of left and right directly with 20 grams/m 2following carding fiber net carries out water thorn composite consolidation, can prepare 30 grams/m 2below, collect light, thin, saturating, good, the high moisture absorption of pro-skin, be not easily deformed in the high-performance water acupuncture manipulation joint product of one, but be actually impracticable.Because in Conventional spunbond cloth, roll a fiber at place well-bonded, original fibre structure is entirely destroyed, be difficult at water thorn compound tense, the fiber hydrolization at these bonding point places be reduced, because the gross area of these bonding points is larger, account for about 20% of non-weaving cloth area, greatly consume water thorn usefulness, when water thorn pressure reaches 50bar, press during staple card net is belonged to, but concerning spunbond net, due to the impact of bonding point, greatly hinder the IPN between filament web and web of staple fibers and entanglement, cause product layering.If when hydraulic pressure is enlarged to 100bar, due to connection and the traction action of bonding point, cause the fabric width of spunbond net significantly to shrink, cause grammes per square metre to improve rapidly, grammes per square metre usually can be made to increase about 50%.
In order to reduce the impact of bonding point, someone attempts spinning fibre net is direct and the composite spunlaced reinforcing of carding fiber net, to obtaining good permeability, constitutionally stable joint product, but test shows, not through the spinning fibre net of consolidation process, because lose the constraint of bonding point 6, the modulus of adding spinning fibre net common is at present larger, fiber is more thick and stiff, is easy to be broken up by water thorn power, cannot become cloth.In order to make fleece do not broken up, only having and the grammes per square metre of spun-bonded fibre net is increased to 30 grams/m 2above, to strengthen fibroreticulate saturation force, and the grammes per square metre of carding fiber net also needs at 20 grams/m simultaneously 2above.Also namely, fibroreticulate total grammes per square metre is at 50 grams/m 2time above, just likely under the effect of water thorn power, tangle into cloth.This kind of material is conventional does filtering material, and grammes per square metre generally rests in 60 grams/m 2left and right.And facial film and protective pad plane materiel not only require that its nonwoven product must have good moisture absorption and moisture-inhibiting ability, also must be frivolous, grammes per square metre generally need control at 40 grams/m 2below, if can control at 30 grams/m 2better below.Visible, traditional spinning fibre net or spun-bonded fibre net and carding fiber net are simply carried out compound, is difficult to produce 30 grams/m 2following product, is difficult to satisfied light, thin, saturating requirement.Also after someone attempts to carry out saddening to spinning fibre net, then with carding fiber net compound, to reduce the impact of spinning fibre net bonding point, can in order to the maturation process scheme of Instructing manufacture but have no.Because only to the enterprising Row sum-equal matrix of hot rolling technology, and do not have the cooperation of fibre modification and water jet process, not having complete theoretical direction, is inconvenient.Because bonding point is excessively firm, cause spun-bonded fibre net to shrink, otherwise because of bonding point excessively weak, fiber is thick and stiff, causes fleece to be broken up, and very difficultly stably makes grammes per square metre at 40 grams/m 2following product.Although spun-bonded fibre net (or spinning fibre net) and carding fiber net are carried out water and sting composite consolidation and become the developing way paid close attention in the industry, up to the present, there is not yet grammes per square metre at 35 grams/m 2below, collect light, thin, saturating, good, the high moisture absorption of pro-skin, be not easily deformed in one water jet bonding composite non-woven cloth.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provide a kind of and adopt Hydroentangled mode to carry out compound to spun-bonded fibre net and carding fiber net, grammes per square metre controls at 40 grams/m 2below, under there is the prerequisite of light, thin, saturating, good, the high moisture absorption of pro-skin, the advantage such as not yielding, permeability by force, not reverse osmosis leak, surface moment soon dry and comfortable, soft, do not rub chafe possess antibacterial, ventilative, the refrigerant dry and comfortable protective pad of healthy functions of body surface height of natural antibacterial, fungistatic effect.
