Description
Technical field
The invention belongs to coating art, is specifically arranged for a kind of non-woven fabrics Hot melt adhesive tape and its coating method and painting
Put.
Background technology
Wound has very high requirement for the water imbibition and gas permeability of dressing.Or dressing on the market have water imbibition but
Lack gas permeability, otherwise there is gas permeability but lack water imbibition, it is difficult to meet two requirements of water imbibition and gas permeability simultaneously, particularly
Gas permeability.PUR dressing base material is polyurethane film and PE films mostly on the market, and permeability is poor.
Non-woven fabrics is also known as adhesive-bonded fabric, is to be made up of fiber orient or random, is environment-friendly materials of new generation, because having
The outward appearance of cloth and some performances and be called cloth.Non-woven fabrics has moistureproof, ventilative, flexible, light, not combustion-supporting, easy decomposition, nothing
The features such as poison is nonirritant, rich in color, cheap, recyclable.As used polypropylene more（Pp materials）Pellet is original
Material, batch continuous one-step through high-temperature fusion, spinneret, paving guiding principle, hot pressing and produce.
Specifically, non-woven fabrics has advantages below：
It is 1. light：Using acrylic resin as main production raw material, proportion only 0.9, only 3/5ths of cotton, have bulkiness,
Good hand touch；
It is 2. soft：(2-3D) is formed by fine fibre and dubs the shaping of shape hot melting cohesion, finished product pliability is moderate, has comfort；
3. drying, breathe freely：Polypropylene chip does not absorb water, and moisture content zero, finished product water-repellancy is good, and it is porous to form tool by 100% fiber
Property, gas permeability is good, and easy holding cloth cover is dry and comfortable, uncomplicated laundering；
It is 4. nontoxic, nonirritant:Using the production of FDA food grade materials is met, without other chemical compositions, stable performance, nontoxic,
Free from extraneous odour, do not stimulate skin；
5. antibacterial, anti-chemical agent：Polypropylene category inactivity material, does not damage by worms, and can isolate and liquid Endophytic bacteria and worm be present
The erosion of class；Antibacterial, caustic corrosion, finished product do not influence intensity because of erosion；
6. antibiotic property：Product tool pulls out water-based, not mouldy, and can isolate the erosion that liquid Endophytic bacteria and insects be present, not mould moth；
7. physical property is good：Directly it is paved into net hot adhesion by polypropylene spinning to form, the relatively general short fine product of product strength is preferred, intensity
Non-directional, vertical transverse strength is close；
8. in terms of environmental protection, the raw material of the most of non-woven fabrics used are polypropylene, and the raw material of polybag are polyethylene,
Although two kinds of material names are similar, differed greatly in chemical constitution；The chemical molecular structure of polyethylene has quite strong
Stability, it is extremely difficult to degrade, thus polybag need 300 years ability decomposable asymmetric choice nets finish；And polyacrylic chemical constitution is insecure, point
Subchain is easy for being broken, and so as to effectively degrade, and enters next step enviromental cycle in nontoxic form, and one
Individual non-woven fabric shopping bag can in 90 days is thoroughly decomposed.And reusable more than 10 times of non-woven fabric shopping bag, discard
Also there was only the 10% of polybag to the dustiness of environment afterwards.
Therefore, non-woven fabrics medical treatment, health field tool have been widely used, and such as can be used for：Operating coat, protective garment, sterile package
Cloth, mouth mask, diaper, civilian rag, cleaning wiping cloth, Moistured towel, magic towel, flexible towel scroll, cosmetic products, sanitary napkin, panty liner,
And disposable hygienic cloth etc..However, the main gel of adhesive-bonded fabric dressing is acrylic compounds glue mostly, colloid is than relatively thin, water imbibition
Can be poor, the requirement of medical dressing can not be met.
The content of the invention
If PUR and non-woven fabrics perfect adaptation can be made into hot-melt adhesive non-woven fabric dressing, can meet to absorb water simultaneously
Property and gas permeability of both require.However, common hot-melt adhesive non-woven fabric coating process shortcoming is obvious：According to directly coating
Hot composition process, PUR can ooze out nonwoven surface；According to the coated cold combination process retransferred, PUR and nothing
It is poor to spin cloth bonding fastness, is easily peeled off.So hot-melt adhesive non-woven fabric dressing is hardly visible on the market.
In view of this, in order to solve the problems, such as that existing PUR and non-woven fabrics coating process is present, the purpose of the present invention exists

Arrive, or produce to obtain using the apparatus for coating of non-woven fabrics Hot melt adhesive tape as described above, as shown in Figure 2.
The coating method of the non-woven fabrics Hot melt adhesive tape of the present embodiment, release liners A and release liners B are answered first with PUR
It is combined, after then release liners B is peeled off, obtains the PUR face to be composite of surfacing, then directly answer non-woven fabrics
Close on the face to be composite of PUR, can effectively prevent PUR strike-through, while ensure have between non-woven fabrics and PUR
Enough viscosity, it is not easy to peel off.
The non-woven fabrics Hot melt adhesive tape obtained using the coating method of the present embodiment non-woven fabrics Hot melt adhesive tape is had the characteristics that：
1）Together with PUR and non-woven fabrics perfect adaptation, allow and dressing while meet water imbibition and gas permeability, disclosure satisfy that doctor
With the requirement of dressing；
2）PUR, which is compounded on non-woven fabrics, had not only been not easily stripped but also will not ooze out excessive glue.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
Enclose not limited to this.The equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, in the present invention
Protection domain within.Protection scope of the present invention is defined by claims.
