METHOD, TOOL AND SYSTEM FOR PRODUCING A PRODUCT FROM A FIBER MATERIAL

A fiber material is filled into a cavity of a tool to produce a product from the fiber material. The tool comprises a mold which defines the cavity therein and a holder which supports the mold. The holder is displaced to move the mold to at least one thermal treatment station The fiber material is thermally treated in the mold at the at least one thermal treatment station.

A NEW MULTI-LAYER INTERLINING AND THE PRODUCTION PROCESS THEREOF

Disclosed is a new multi-layer nonwoven interlining and the production process thereof. The process allows a multi-layer nonwoven interlining to be obtained simultaneously with a single process on a single production line. The process includes a fiber opening step, a fiber feeding step, a carding step, a levelling step of the additional layer by the thermal treatment, and a point bonding step of the carded web and additional layer. As a result of the process, a structure is obtained where the carded web is point-bonded onto the additional layer.

METHOD FOR THE CONTINUOUS PRODUCTION OF NONWOVEN FABRIC, AND ASSOCIATED NONWOVEN FABRIC PRODUCTION APPARATUS AND NONWOVEN BOARD
20230228018 · 2023-07-20 ·

A method for the production of a continuous nonwoven fabric from fiber mixtures of carrier fibers and binding fibers, comprising the steps: a. Feeding fibers; b. Breaking up, combing and opening out the fibers; c. Mixing the fibers; d. Sucking the fibers between two opposing airpermeable conveyor belts running at identical speed, such that the air is sucked from the outside in the front section of the conveyor belts in such a way that the air flow is always sucked through the deposited nonwoven fabric by air extraction at different times and different locations across the width and parallel to the conveyor belts and the fibers are thereby positioned perpendicular to the surface of the conveyor belts; e. Thermally solidifying the nonwoven fabric created by heating with hot air or shortwave radiation and cooling. Also a nonwoven fabric production apparatus.

Apparatus for making nonwoven fabric from fibers

An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.
