20220307173 · 2022-09-29 · ·

A system for bonding at least one wet-laid or dry-laid fiber layer to form a nonwoven web. The system includes a conveyor having a circulating belt which has an upper strand arranged so that the at least one wet-laid or dry-laid fiber layer is deposited and displaced on the upper strand in a production direction, a first bonding device which bonds the at least one wet-laid or dry-laid fiber layer when on the upper strand, a second bonding device arranged so that the at least one wet-laid or dry-laid fiber layer is bonded after leaving the upper strand, and a transfer device which feeds the at least one wet-laid or dry-laid fiber layer to the second bonding device.

SYSTEM FOR BONDING LAYERS COMPRISING FIBERS TO FORM A NONWOVEN WEB

A system for bonding a first layer having short fibers with a second layer having long fibers into a nonwoven web. The system includes a belt, a headbox, a depositing belt with a delivery strand, a transfer belt with a receiving strand, a device, a pre-bonding unit, and a bonding device. The short fibers are deposited on the depositing belt to form the first layer with the headbox. The transfer belt transfers the first layer to the second layer. The pre-bonding unit has spaced-apart compacting devices which act on the transfer belt to form a lower strand of the transfer belt there between. The bonding device is arranged between the compacting devices. The bonding device bonds the first and second layers. The compacting devices and the bonding device are operatively connected to one another so that they are each always either in an operating state or in a resting state.

APPARATUS AND METHOD FOR BONDING LAYERS COMPRISING FIBERS TO FORM A NON-WOVEN WEB

An apparatus for bonding a first layer having short fibers with a second layer having long fibers into a non-woven web. The apparatus includes a first circulating belt on which the second layer is depositable and displacable, a second circulating belt via which the first layer is transferable at a transition point to the second layer, a pre-bonding unit arranged directly behind the transition point, and a bonding device. The pre-bonding unit has compactors which are spaced apart from one another. The compactors act in one region on the first or second circulating belt. The bonding device is arranged between the compactors and bonds together the first and second layers. The compactors and the bonding device are integrated into the apparatus to together be in an operating state when the first layer is transferred using the second circulating belt.

Cleaning sheet

This cleaning sheet is provided with an embossed part in which the sheet is compressed in the thickness direction. The cleaning sheet is provided with outer layers, forming the surfaces of the sheet; and an inner layer sandwiched between the outer layers. In the boundary areas between the outer layers, and the inner layer, the fibers of the layers are entangled. This allows for a sheet that better retains the raised and sunken shapes embossed therethrough and exhibits excellent collecting performance.

WOUND CLEANING PRODUCT
20220203650 · 2022-06-30 ·

A wound cleaning product is described as used for sterile debridement of wounds. The wound cleaning product comprises a composite material having a foam layer and a fiber layer arranged on a surface of the foam layer. The fiber layer is at least partially thermally solidified, and the foam layer and the fiber layer are connected to one another by needling such that fibers of the fiber layer have penetrated into the foam layer and form capillary channels that extend from the fiber layer into the foam layer.
