Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a production process for fine denier waterproof and moisture-permeable fabrics. The production process pre-laminates the bottom layer and the surface layer on the release paper, and then transfers the bottom layer and the surface layer to the base fabric. Above, the bottom layer bonds the surface layer and the base fabric, and the bottom layer covers the gaps in the base cloth, and the bottom layer and the surface layer have hydrophilic groups, which can interact with water molecules at high temperatures by means of hydrogen bonds or other intermolecular forces. Adsorb water molecules on the side, and desorb on the low-temperature side through the hydrophilic group, thus solving the problem that the current fine denier fabrics cannot balance moisture permeability and waterproof functions

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, a production process of a fine denier waterproof and moisture-permeable fabric, including:

[0023] (1) Raw material configuration; mix 100 parts by weight of PU resin, 40 parts by weight of solvent, and 1 part by weight of additives as a surface layer rubber; mix 100 parts by weight of PU resin, 20 parts by weight of solvent, 6 parts by weight of bridging agent, 1 Accelerators are mixed in parts by weight as the bottom rubber; the oily solvents in the above surface rubber are TOL and DMF, and the percentages of these two components in the oily solvent are: TOL55%, DMF45%. The solvents in the above primer are TOL and DMF, and the proportion of each component in the oily solvent is: 45%, 55%. The bridging agent is NCO, and the accelerator is an enzyme, and its function is to accelerate the curing of the bottom polyurethane . The surface layer rubber and the bottom layer rubber are stirred evenly and then added to different coatin...

Embodiment 2

[0030] The production process of this embodiment is basically the same as that of Embodiment 1, except that the parameters are slightly adjusted. Among them, 100 parts by weight of PU resin, 70 parts by weight of solvent, and 2 parts by weight of auxiliary agents are mixed as surface rubber; Mixed as the bottom rubber material; drying temperature of the surface rubber material: 80-120°C, semi-drying temperature of the bottom layer rubber material: 80-20°C, lamination wheel temperature: 120°C, pressure wheel pressure: 3KG, aging time: 48H , Ripening temperature: 65°C, speed of release paper and base cloth: 30m / min. TOL accounts for 65% and DMF accounts for 35% in the oily solvent of the top glue, and TOL35% and DMF65% in the oily solvent of the bottom glue.

Embodiment 3

[0032] The production process of this embodiment is basically the same as that of Embodiment 1, except that the parameters are slightly adjusted. Among them, 100 parts by weight of PU resin, 50 parts by weight of solvent, and 1.5 parts by weight of auxiliary agents are mixed as surface rubber; Mixed as the bottom rubber material; drying temperature of surface rubber material: 80-120°C, semi-drying temperature of bottom layer rubber material: 80-20°C, lamination wheel temperature: 110°C, pressure wheel pressure: 4KG, aging time: 36H , Ripening temperature: 65°C, speed of release paper and base cloth: 25m / min. In the oily solvent of the top glue, TOL accounts for 60%, DMF accounts for 40%, in the oily solvent of the bottom glue, TOL40%, DMF60%.

Abstract

The invention discloses a production process for a fine-denier waterproof and moisture-permeable fabric. The production process comprises the following steps of: (1) proportioning raw materials; (2) coating a surface-layer adhesive onto release paper, and drying to form a surface layer; (3) coating a bottom-layer adhesive onto the surface of the surface layer, and carrying out half-drying; (4) unreeling base cloth woven by 8-20D fibers at the same speed as that of the release paper, reeling after the base cloth and a bottom layer are attached to form a semi-finished product; and (5) peeling the release paper after the semi-finished product is cured. According to the production process, the bottom layer and the surface layer are attached on the release paper in advance, then the bottom layer and the surface layer are transferred onto the base cloth, the surface layer and the base cloth are adhered by utilizing the bottom layer, the bottom layer covers gaps of the base cloth, and the bottom layer and the surface layer have hydrophilic groups which can act with water molecules to adsorb the water molecules at one high-temperature side by virtue of hydrogen bonds or other intermolecular forces and transfer the water molecules to one low-temperature side through hydrophilic radicals to carry out desorption, so that a problem that the moisture-permeable function and the waterproof function of the conventional fine-denier fabric cannot be simultaneously considered is solved.

Description

technical field [0001] The invention relates to a production process of a fabric, in particular to a production process of a fine denier waterproof and moisture-permeable fabric. Background technique [0002] At present, the waterproof and moisture-permeable effect of fine denier fabrics is generally inconsistent. The main reason is that the thickness of fine denier fabrics is very thin, so water molecules can easily penetrate the gaps between the fibers inside the fabrics. At present, there are also chemical treatments for fine denier fabrics. Generally, one side of the fine denier fabrics is coated with a non-porous coating. This coating can block the fiber gaps in the fabrics, thus improving the waterproof function. , but because the fiber gap is blocked and the coating itself is non-porous, clothes made of this fabric will be very airtight when worn on the body, and the sweat and heat produced by the human body cannot be dissipated through the clothes in time. Therefore...
