Description

Technical Field

[0001] The utility model belongs to the technical field of unilateral moisture-conducting nonwoven fabric processing, in particular to unilateral moisture-conducting nonwoven fabric processing equipment. Background Art

[0002] In the field of facial masks, people often use unidirectional moisture-conducting nonwoven fabrics to ensure that the essence can be conducted to the skin instead of being lost in the air or evaporated by the air. Fibers with different hydrophilicity or hydrophobicity, or the two sides of the material usually have a wetting gradient, which can achieve unidirectional conduction of liquid. Using this property, people have developed unidirectional moisture-conducting nonwoven fabrics.

[0003] One-way moisture-conducting nonwoven fabrics are developed on the basis of moisture-absorbing and quick-drying nonwoven fabrics. One-way moisture-conducting nonwoven fabrics have the following characteristics: liquid or water can only be transferred from one side of the nonwoven fabric to the other side, but not the reverse side. For example, liquid can only be transferred from the hydrophobic side of the nonwoven fabric to the hydrophilic side, but not from the hydrophilic side to the hydrophobic side. In order to make the nonwoven fabric have the one-way moisture-conducting function, one side of the fabric is kept hydrophilic and the other side is kept hydrophobic, or there is an obvious wetting gradient on both sides of the fabric, so that the fabric has the ability of directional moisture conduction.

[0004] Membrane cloths with different hydrophilicity and hydrophobicity, membrane cloths with different pore sizes, and membrane cloths with different fiber fineness are generally two-layer composites and processed into unidirectional moisture-conducting non-woven fabrics. However, the unidirectional moisture-conducting non-woven fabrics processed in this way sometimes have unclear unidirectional moisture-conducting properties. For this reason, a processing method has been developed in which a hydrophilic layer and a hydrophobic layer are coated on both sides of the membrane cloth body with certain unidirectional moisture-conducting properties mentioned above, so as to improve the unidirectional moisture-conducting properties of the membrane cloth and better meet people's needs.

[0005] Although the existing unidirectional moisture-conducting non-woven fabric processing equipment can meet the basic needs of unidirectional moisture-conducting non-woven fabric processing, the spraying widths of the hydrophilic coating spraying structure and the hydrophobic coating spraying structure used are often fixed and cannot be adjusted, so that users can only spray membrane cloth of a single width. When the width of the membrane cloth is smaller than the spraying width, it is easy to cause waste of coating. When the width of the membrane cloth is larger than the spraying width, it will lead to the inability to fully cover the area of ​​the membrane cloth to be sprayed, which will bring great inconvenience to people's use.

[0006] For example, the utility model with announcement number CN 218531488 U discloses a double-layer unidirectional moisture-conducting fabric processing equipment. In the technical solution of this patent, the hydrophilic additive and the water-repellent finishing agent are sprayed onto the membrane cloth body through a coating roller with a fixed width. Since the width of the coating roller is fixed and cannot be adjusted, it can only be applied to membrane cloth with a fixed width, and has the defect of limited scope of application.
