Description

High-moisture-permeability soft shell fabric

Technical Field

The utility model relates to the field of fabrics, in particular to a soft shell fabric with high moisture permeability.

Background

With the improvement of living standard, more and more people participate in outdoor sports. Outdoor sports become a part of fashion life, running, jumping, climbing and the like have become a part of daily life, however, most of the current products discharge water vapor out of the body through hydrophilic groups of polyurethane, such as-OH, -COOH, in a mode of adsorption-desorption-adsorption and the like, the effect of the mode is slow, the mode is greatly influenced by the external environment (temperature and humidity), and when a human body does exercises, moisture is difficult to rapidly discharge out of the body, so that the body feels damp and stuffy.

In the prior art, the manufacturing process of a common soft shell fabric is realized by desizing, dyeing, water splashing and shaping, composite polyurethane film, polar fleece and the like, and the problems of relatively poor moisture permeability after the polyurethane film is compounded, influence of environmental change on the moisture permeability, poor moisture permeability at low temperature and the like also exist.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems that the moisture permeability of the soft shell fabric in the prior art is relatively poor, the moisture permeability is influenced by environmental change, and the moisture permeability is poor at low temperature, the utility model increases certain holes after the fabric and polyurethane are compounded by punching the film, thereby being beneficial to the outward discharge of water vapor. The specific technical scheme is as follows:

the high-moisture-permeability soft shell fabric sequentially comprises a fabric layer, a film layer and a polar fleece layer from top to bottom, wherein pinholes are formed on the film layer. Through punching the film, certain holes are formed in the composite fabric and the film, so that the outward discharge of water vapor is facilitated, and the moisture permeability of the fabric is improved.

Preferably, the aperture of the pinhole is 0.01mm-0.04 mm. And in the punching treatment, punching equipment is adopted to punch the fabric compounded with the film, and the aperture is 0.01-0.04 mm. The types of the needles are selected from 7-9, and the main reason for selecting the types of the needles is to avoid the thermosol from completely blocking the needle holes and avoid the phenomenon of generating needle holes on the cloth surface during subsequent shaking compounding.

Preferably, the pinholes on the thin film layer are distributed in a square matrix, and the distance between every two adjacent pinholes is 0.3cm-0.5 cm. Punching to form a square matrix with the pinhole spacing of 0.3cm-0.5 cm. The square matrix with the pin hole spacing of 0.3cm-0.5cm is mainly used for ensuring that the damage to the membrane surface is controlled within a certain range, so that the water pressure is not reduced too much.

Preferably, the film layer has a thickness of 0.015mm to 0.02 mm.

Preferably, the film of the film layer is a PU film or a TPU film.

Preferably, the fabric layer is spandex elastic fabric.

Preferably, the fabric layer is prepared by taking 75D terylene four-side elastic as grey cloth and performing desizing, blank setting, dyeing, setting, drying and water splashing setting.

Preferably, the fabric layer and the film layer are compounded through hot melt adhesive.

Preferably, the hot melt adhesive is a PUR hot melt adhesive.

Preferably, when the fabric layer and the film layer are laminated, the coating gap (the distance between the glue and the film) is less than 0.15mm, and the lamination gap (the distance between the film and the cloth) is 0.2 mm.

Preferably, the film layer and the polar fleece layer are compounded through hot melt adhesive.

The technical scheme of the utility model has the following beneficial effects:

(1) through punching the film, certain holes are formed in the composite fabric and the film, so that the outward discharge of water vapor is facilitated, and the moisture permeability of the fabric is improved.

(2) The square matrix with the pin hole spacing of 0.3cm-0.5cm is mainly used for ensuring that the damage to the membrane surface is controlled within a certain range, so that the water pressure is not reduced too much.
