Description

Technical Field

[0001] The utility model relates to the technical field of pu film production equipment, in particular to a pressing device for a pu film after hot melting. Background Technique

[0002] PU is the abbreviation of Polyurethane, and its Chinese name is polyurethane, simply referred to as pu. PU is polyurethane, and the pu film is a polyurethane film, which is a non-toxic and harmless environmental protection material and has no harm to the human skin. It is widely used in clothing fabrics, medical and health, leather and other fields.

[0003] It has good elasticity and high strength. In terms of waterproof performance, although the thickness is extremely thin (0.012 - 0.035mm), it has physical properties that cannot be compared with other materials (it can withstand a water pressure of more than 10,000mm water column). By using high-tech technology to introduce a hydrophilic agent into the material, the film not only has high waterproof performance but also has excellent moisture permeability (human sweat can freely penetrate between the films). This breakthrough in function, combined with the lamination processing technology of the textile industry, greatly improves the added value of textiles. It is now widely used in snow clothes, windbreakers, cold-proof jackets, and gloves.

[0004] The prior art has the following defects or problems: The existing pressing device for a pu film after hot melting uses a relatively cumbersome method to complete the pressing process of the pu film, resulting in reduced efficiency and requiring a large amount of manpower and material resources to complete.
