Description
Technical field
The invention belongs to cosmetic product technical field, in particular to it is a kind of it is frivolous can be with the composite facial mask base fabric of wire drawing.
Background technique
It is well known that facial mask has become essential articles in current people seeking beauty's life, because it is bright with effect
Aobvious, advantage easy to use is widely used to promote, and facial mask is a kind of carrier of face beautifying health keeping product, application on the face 15 ~
30 minutes.After the nutrient of skin care products is slowly absorbed by the skin, that is, the film unloaded down, powder reconciliation at present, kaolin, nonwoven
Cloth and silk mask, tencel facial mask, Biofibre facial mask material facial mask use it is very extensive.Facial mask is one in skin care item
A classification.Its most basic and most important purpose is to make up makeup removing and the still insufficient cleaning that washes one's face, on this basis
Other essential ingredients are cooperated to realize other maintenance functions, such as replenishing water and preserving moisture, whitening and anti-aging, Sage Extract etc..Facial mask
Principle be temporarily isolating extraneous air and pollution exactly using the of short duration time for being covered on face, improve skin temperature, skin
The pore of skin is expanded, and is promoted sweat gland secretion and metabolism, increase the oxygen content of skin, is conducive to skin and is excluded epidermal cell
The product of metabolism and the oil substances of accumulation, the moisture in facial mask penetrate into the cuticula of epidermis, and skin becomes soft, flesh
Skin is naturally bright flexible.The form of facial mask mainly has mud paste type, tear-pull, gel-type, four kinds of hygenic towelette type.Mud paste type facial mask
It common are seaweed mask, sludge facial mask etc., the most common tear-pull facial mask is exactly the dedicated nose patch of blackhead, and gel-type is to sleep
Dormancy facial mask is the most famous, and hygenic towelette formula is generally exactly the face paper for infiltrating beautifying liquid of mmic package.Along with beauty science and technology
Development, occur one kind with facial mask made of silk, strictly speaking, should be included into hygenic towelette type facial mask.
Why facial mask has an outstanding maintenance effect, most important " package " effect for lying also in facial mask, enable skin with
Air is completely isolated, and skin is allowed to fully absorb nutrition." package " effect requires facial mask to be adjacent to skin, and being adjacent to skin will
Mask substrate is asked to need good water absorption, soft, the trend of facial mask is light, thin, saturating at present, and if existing facial mask is accomplished
Gently, thin, saturating, then the ability for absorbing Essence will be greatly reduced, and it is compatible can not to accomplish three, once Essence uptake is few, face
Film will be unable to be tightly attached to facial skin, and spunbond technology is the new skill of non-woven cloth that gradually grows up in the fifties later period in last century
Art is chemical fibre technology most successful model in conjunction with nonwoven techniques.Spun-bond process production technology can 10 grams/m of industrialization production2
Left and right Spunbonded Nonwovens, and have the advantages that light, thin, saturating and strength is high, but since its fertile product of institute only limits
In thermoplastic fibre, such as polypropylene fibre, terylene and polyamide fibre, therefore its feel, the ability of absorption Essence and pro-skin sense are bad, very
Difficulty is directly used in facial mask.And the staple fiber of most of types, such as cotton, silk, viscose glue and all kinds of chemical fibres can be combed by combing networking method
Grammes per square metre is made in 20 grams/m in reason2Web below.Seem.It can be by 10 grams/m2Left and right spinning building directly with 20 grams/m2With
Lower carding fiber net carries out spun lacing composite consolidation, can prepare 30 grams/m2Hereinafter, collection it is light, thin, saturating, pro-skin is good, it is highly hygroscopic,
It is unlikely to deform in the high-performance water acupuncture manipulation joint product of one, but it is actually unworkable.Because being rolled in Conventional spunbond cloth
Fiber at point is well-bonded, and original fibre structure has been entirely destroyed, and is difficult to bond these in spun lacing compound tense
Fiber hydrolization reduction at point, since the gross area of these bonding points is larger, accounts for about 20% or so of non-woven cloth area, greatly
Ground consumes spun lacing efficiency, when spun lacing pressure reaches 50bar, to staple card net belonged in press, but for spunbond net,
Due to the influence of bonding point, the interpenetrating and entanglement between filament web and web of staple fibers are greatly hindered, leads to product point
Layer.If hydraulic pressure is enlarged to 100bar, due to the connection and traction action of bonding point, cause the breadth of spunbond net significantly
It shrinks, grammes per square metre is caused to improve rapidly, grammes per square metre can usually be made to increase by 50% or so.In order to reduce the influence of bonding point, attempt to by
Spinning fibre net directly with the composite spunlaced reinforcing of carding fiber net, is desirably to obtain the joint product of good permeability, stable structure, but
Be experiments have shown that, the spinning fibre net not Jing Guo consolidation process because losing the constraint of bonding point 6, along at present often
The modulus for the spinning fibre net seen is larger, and fiber is more thick and stiff, it is easy to it is broken up by spun lacing power, it can not be at cloth.In order to make web
It is not broken up, the grammes per square metre of spun-bonded fibre net is only increased into 30 grams/m2More than, to increase the saturation force of web, and comb simultaneously
The grammes per square metre of reason web is also required in 20 grams/m2More than.That is, total grammes per square metre of web is in 50 grams/m2When above, be possible to
It tangles under the action of spun lacing power into cloth.This kind of material is common to do filtering material, and grammes per square metre generally rests in 60 grams/m2Left and right.And
Facial mask and sanitary napkin plane materiel, which do not require nothing more than its nonwoven product, must good moisture absorption and moisture-inhibiting ability, it is necessary to and it is frivolous,
Grammes per square metre need to generally be controlled in 40 grams/m2Hereinafter, if can control in 30 grams/m2It is more preferable below.As it can be seen that by traditional spinning fibre
Net or spun-bonded fibre net simply carry out compound with carding fiber net, are difficult to produce 30 grams/m2Product below, it is difficult to meet
Gently, thin, saturating requirement.Also it attempts to after carrying out saddening to spinning fibre net, then compound with carding fiber net, to reduce spinning
The influence of web bonding point, can be to the mature technology scheme of Instructing manufacture but have no.Because only on hot rolling technology
It is adjusted, has any problem without the cooperation of fibre modification and water jet process without complete theoretical direction.Cause
It is excessively firm for bonding point, cause spun-bonded fibre net to shrink or because bonding point is excessively weak, fiber is thick and stiff, causes web to be broken up, very
Hardly possible steadily produces grammes per square metre in 40 grams/m2Following product.
Although spun-bonded fibre net (or spinning fibre net) and carding fiber net are carried out spun lacing composite consolidation to have become in the industry
The developing way of concern, 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, high
Moisture absorption is unlikely to deform in the spun lacing composite non-weaving cloth of one.Therefore, how to develop it is a collection it is light, thin, saturating, pro-skin is good, high suction
It is wet, be unlikely to deform in one high performance mask substrate have become those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
In view of the deficienciess of the prior art, being twined the technical problem to be solved by the invention is to provide a kind of using waterpower
The mode of knot is compound to spun-bonded fibre net and carding fiber net progress, and grammes per square metre is controlled in 35 grams/m2Hereinafter, have it is light, thin, saturating,
Pro-skin is good, under the premise of highly hygroscopic, the advantages that being unlikely to deform, and can have the frivolous of high-tenacity performance can be with the compound of wire drawing
Mask substrate.
In order to solve the above technical problems, the technical solution used in the present invention is: it is a kind of it is frivolous can be with the compound of wire drawing
Mask substrate, including as false bonded spunbond web through carrying out online or with carding fiber net having made of spun lacing reinforcing offline
The essentially false bonded spunbond fibrous layer of middle layer, two surface layers are essentially the Hydroentangled integrated non-woven cloth of carded fiber layer, institute
False bonded spunbond web is stated to be added by hot rolling after the thermoplastic fibre continuous yarn spinning networking after the processing of drop modulus and hydrophilic treated
Admittedly forming, the carding fiber net is by forming the false bonded spunbond web with hydrophilic staple card networking
Hot rolling bonding point is less than the strength of thermoplastic fibre long filament itself to cohesive force caused by fiber between fiber.
Above-mentioned one kind is frivolous can be with the composite facial mask base fabric of wire drawing, and the drop modulus processing and hydrophilic treated are in heat
The drop modulus master batch that thermoplastic fibre spinning chips weight percent is 0.1%~2% is added in Plasitc fibers spinning chips respectively
And 0.4%~4% hydrophilic master batch.
Above-mentioned one kind is frivolous can be with the composite facial mask base fabric of wire drawing, and the drop modulus processing and hydrophilic treated are in heat
The drop modulus master batch for being 0.1%~2% containing thermoplastic fibre spinning chips weight percent is added in Plasitc fibers spinning chips
And 0.4%~4% hydrophilic master batch mixed and modified master batch.
Frivolous above-mentioned one kind can be terylene, polyamide fibre with the composite facial mask base fabric of wire drawing, the thermoplastic fibre long filament
