Description

Special cloth for multi-layer composite mask
Technical Field
The invention relates to cloth for a mask, in particular to multi-layer composite cloth special for the mask, which can simply, quickly, efficiently and high-quality produce the mask.
Background
Baidu Baike (Baidu encyclopedia): the disposable plane mask is made of three or more layers of different non-woven fabrics; the metal wire used as the nose bridge strip is embedded in the nose bridge, and the nose bridge is suitable for electronic factories and daily life. The disposable medical surgical mask can prevent respiratory tract infection and virus harm to a certain extent. The standard size was 17.5cm by 9.5 cm. The disposable masks include disposable two-layer masks, disposable non-woven fabric masks, disposable three-layer masks, and disposable activated carbon masks. The disposable three-layer mask is made of two layers of non-woven fabrics and filter paper; the disposable three-layer mask is made up by using fibre non-woven fabric specially used for medical treatment and health, sandwiching a layer of filter paper (usually melt-blown fabric) and making ultrasonic welding, and its nose bridge portion adopts environment-protecting type full-plastic nose bridge strip, and can be regulated according to different face forms. The ear band/head band and the layers are ultrasonically welded. The mask body is generally provided with a fold, and the mask body is pulled up and down when worn, so that the mask can be unfolded.
When the existing disposable plane mask is manufactured, mask manufacturers need to purchase more than three types of non-woven fabrics from different raw material manufacturers, and the mask can be manufactured through complex processes of unreeling, deviation correction, welding, metal wire embedding, cutting and the like of a forming machine. The existing mask has complex manufacturing process and low production efficiency, so that the mask is short of supply and demand in China only in the period of new coronavirus, and the mask capacity cannot be rapidly improved. In the period of new coronavirus, the daily demand of the mask nationwide is 10 hundred million, the daily production capacity of the mask nationwide in China is 0.2 hundred million, and the gap is 50 times.
Disclosure of Invention
The purpose of the invention is as follows: provides a multi-layer composite cloth special for a mask, so as to produce the mask simply, quickly, efficiently and with high quality (high qualification rate).
The technical scheme of the special cloth for the multilayer composite mask is as follows.
The utility model provides a special cloth of compound gauze mask of multilayer which characterized in that: the composite material at least comprises a spunbonded non-woven fabric outer layer (1), a melt-blown non-woven fabric middle layer (2) and a spunbonded non-woven fabric inner layer (3) in sequence; the layers are bonded together through a plurality of bonding points (4) or bonding lines (5), so that the composite fabric (special for the mask) is formed.
Preferably, the diameter of the bonding point (4) is less than or equal to 1mm, or 0.5mm, or 0.3mm, or 0.2mm, or 0.1 mm; the density of the bonding points (4) is less than or equal to 25/cm2Or 10 pieces/cm2Or 5 pieces/cm2Or 2/cm2Or 1/cm2Or 1/cm2Or 0.1 pieces/cm2。
Preferably, the width of the bonding line (5) is less than or equal to 20 μm or 10 μm or 5 μm or 2 μm; the distance between the bonding points (5) is less than or equal to 5cm or 2cm or 1cm or 0.5cm or 0.3 cm.
Preferably, the bonding points (4) are ultrasonic welding points or UV glue points; alternatively, the bonding line (5) is an ultrasonic welding line or a UV glue line.
Compared with the prior art, the invention can produce the following two beneficial effects.
Firstly, by using the special multi-layer composite mask cloth, a mask manufacturer does not need to purchase more than three types of non-woven cloth fabrics from different raw material manufacturers, and only needs to purchase the special multi-layer composite mask cloth, namely the special composite mask cloth, from one manufacturer.
Secondly, by using the special cloth for the multilayer composite mask, at least two unwinding mechanisms and deviation rectifying mechanisms can be omitted on a mask forming machine, and the welding amount can be reduced.
Thirdly, the special cloth for the multilayer composite mask can reduce more than two roll changing and material receiving processes, thereby reducing the efficiency reduction caused by roll changing, joint and machine halt and the waste caused by mismatched cloth lengths.
Fourthly, the special cloth for the multilayer composite mask can reduce the equipment investment, simplify the production process and greatly reduce the production cost.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.
Fig. 1 is a schematic view of a cloth (roll) specially used for a multi-layer composite mask according to a first embodiment of the present invention.
Fig. 2 is a schematic cross-sectional view at a-B in fig. 1.
Fig. 3 is a schematic view of a cloth (roll) specially used for a multi-layer composite mask in the second embodiment of the present invention.
The reference numbers illustrate: 1-outer layer, 2-middle layer, 3-inner layer, 4-adhesive point, 5-adhesive line and 6-cloth roll.
The first embodiment.
Spun-bonded nonwoven fabric rolls having a wide width (for example, 1024 mm) for the mask outer layer (1), melt-blown nonwoven fabric rolls for the mask intermediate layer (2) (for filtration), and spun-bonded nonwoven fabric rolls for the mask inner layer (3) were purchased from three different nonwoven fabric factories, respectively.
A three-layer compound machine with a breadth of 1024mm was purchased. And (3) loading the three types of coil materials to a compound machine for unreeling and compounding, and then reeling the three types of coil materials into a cloth roll (6).
Preferably, the layers are bonded together through a plurality of bonding points (4) or bonding lines (5) so as to form the composite fabric (special for the mask). The sparse bonding points (4) or bonding lines (5) are adopted, and the traditional full-plate coating composite process is not adopted, so that the prepared composite fabric keeps good air permeability.
In order to keep the prepared composite fabric with better air permeability, the diameter of the bonding point (4) is preferably less than or equal to 1mm or 0.5mm or 0.3mm or 0.2mm or 0.1 mm; the density of the bonding points (4) is less than or equal to 25/cm2Or 10 pieces/cm2Or 5 pieces/cm2Or 2/cm2Or 1/cm2Or 1/cm2Or 0.1 pieces/cm2。
Preferably, the width of the bonding line (5) is less than or equal to 20 μm or 10 μm or 5 μm or 2 μm; the distance between the bonding points (5) is less than or equal to 5cm or 2cm or 1cm or 0.5cm or 0.3 cm.
Preferably, the bonding points (4) are ultrasonic welding points or UV glue points; alternatively, the bonding line (5) is an ultrasonic welding line or a UV glue line.
If the gauze roll (6) manufactured by the mask manufacturer is adopted, more than three kinds of non-woven cloth fabrics are not required to be purchased from a plurality of different raw material manufacturers. During production, at least two unwinding mechanisms and deviation rectifying mechanisms can be omitted on the mask forming machine, and welding quantity can be reduced. The process of changing rolls and receiving materials more than twice can be reduced, so that the efficiency reduction caused by roll changing, joint and shutdown and the waste caused by mismatched cloth lengths are reduced. The equipment investment can be reduced, the production process can be simplified, and the production cost can be greatly reduced.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
