Method and device for processing fabric surface functionality

Abstract

The invention provides a method and a device for processing fabric surface functionality. According to the method and the device, a diluted surface treatment solution is sprayed on the front face and the back face of the fabric by means of a special device by using a spraying and rolling combined method; the special device comprises a fabric conveying roller, a winding roller, a pair of extruding roller, and a plurality of sprayers arranged on and below the extruding rollers; a layer of hair felt or cellulose needled felt, which has excellent hygroscopicity or capillary core absorbing function and is capable of absorbing and maintaining a certain amount of diluted surface treatment liquid, is coated on the surface of each extruding roller; the fabrics run through the extruding rollers in an open-width status. By controlling the fabric speed, the spraying amount and the pressure of the extruding rollers, the surface treatment liquid is enabled to permeate into the front face and the back face of the fabric under the control. The fabrics processed by the method provided by the invention are unlikely to harden after being dried, and the original softness, the air permeability and the hygroscopicity of the fabrics can be held.

Description

technical field [0001] The invention relates to a fabric surface treatment technology, which can be applied to the manufacture of functional fabrics. Background technique [0002] Coating treatment is the most widely used fabric surface treatment technology, including direct scraping or roller coating of coating glue, and lamination film coating method. In addition, finishing agents containing various active ingredients are often used for fabric padding treatment. These two methods can form a functional film on the surface of the fiber or fabric, so that the fabric can obtain additional functions that it did not have originally, such as flame retardant, oil-repellent and waterproof, antibacterial and anti-mildew functions, etc. However, direct coating of coating glue or lamination film coating treatment will obviously change the original surface properties of the fabric, such as touch feel and gloss, etc., and will also affect its air permeability and moisture permeability....

AI Technical Summary

Problems solved by technology

However, the direct coating of coating glue or lamination film coating treatment will obviously change the original surface properties of the fabric, such as touch feel and gloss, etc., and will also affect its air permeability and moisture permeability.

The padding treatment method can make the surface treatment agent permeate the fabric, and the surface treatment agent forms a film on the surface of the fiber. Although the impact on the surface properties of the fabric is lower than that of the coating method, most surface functional treatment agents contain a considerable proportion of binders. Surface treatment After the agent completely soaks the fabric, the fibers are bonded to each other. After the fabric is dried, it will cause overall hardening, which will seriously affect its softness and hand feeling, and will also affect its elasticity.

The existing fabric surface functional treatment methods have different degrees of adverse effects on the original properties of the fabric, especially for natural fiber fabrics, which will affect its original soft feel, air permeability and hygroscopicity, etc.
