Embodiment Construction

[0034] The present invention relates to a three-dimensional (3D) multifunctional knitted structure comprising an inner knitted layer, an outer knitted layer, connecting cross threads and a coated / laminated film on the outer layer. 3D structures (except coated / laminated films) are used on flat or circular knitting machines on the dial and cylinder (when knitting circular) and on the front needle bed and Special stitch combinations performed on the rear needle bed (in the case of plain weaving technology) are produced integrally and in a single step. This combination of special coils enables the fabrication of two separate layers (inner and outer layers) connected by monofilament threads oriented in the thickness direction, thus giving the structure the three-dimensionality required for the application. The functionality given to the structure is provided by the orientation of the fibers in the structure itself and by the use of functional fiber yarns with specific characteristi...

Abstract

This invention provides a three-dimensional (3D) multifunctional knitted fabric structure comprising two independent layers (1 and 3) connected by cross-threads (2) being able to be applied as absorbency structure in medium incontinence men's reusable underwear. The structure is produced in a single step using weft-knitting technology and designed to perform several functions in a single fabric. The inner layer (1), to be in contact with human body, is responsible to transport liquid, urine and perspiration from the human body to the outer layer (3), through the cross-threads (2), keeping dry the human skin. Cross-threads (2) are responsible to keep apart both independent layers and to transport liquid from the inner layer (1) to the outer layer (2). The outer layer (3) is responsible to absorb the liquid and, at same time, to control the odor and microorganisms proliferation generated by the urine. The outer layer (3) is coated or laminated (4) with a moisture control polyurethane in order to prevent liquid passage to the user paints and at same time to provide vapor transmission.

Description

technical field [0001] The present invention relates to a three-dimensional (3D) multifunctional knitted structure manufactured in a single step using weft knitting technology, comprising two separate layers connected by crossing threads, specifically designed to perform as a reusable underwear for moderately incontinent persons Multiple functions of the absorbent structure, including liquid transport, drying the skin, deodorant and antimicrobial. Background technique [0002] The textile structure plays an important role in the performance of the entire textile system. Three-dimensional structure (3D) is the organization and integration of groups of fibers with multiaxial orientation. Used in different orientations of the fibers, this fabric has high performance and is suitable for a wide range of uses, such as multifunctionality (different layers have different functions), elasticity and porosity. [0003] Three-dimensional (3D) fabrics can be fabricated using the most c...
