Abstract: The invention relates to a flexible bulk-material container made of at least one woven blank of a synthetic strip-type material and to a method for the production thereof. In the seam areas (25),the woven blank (20.1) is provided with an overlapping or another woven blank (20.2) placed on top. An energy conversion agent 924) is inserted into the boundary layer (22) which is disposed between the overlapping and/or woven blanks placed on top (20.1, 20.2). The woven blank or blanks (20.1, 20.2) is/are melted by means of laser beams acting upon the energy conversion agent (24).

Abstract: The invention relates to a method for laser welding, wherein n plastic parts (1.1, . . . , 1.n) are pressed against each other, respectively forming a boundary layer (2.1, . . . , 2.n-1). An energy-converting medium (4.1, . . . , 4.n-1) is incorporated into each boundary layer (2.1, . . . , 2.n-1) and absorbs the light energy of at least one of several laser beams used (11.1, . . . , 11.m). Irradiation of the boundary layers (2.1, . . . , 2.n-1) by means of the laser beams (11.1, . . . , 11.m) respectively results in a partial melt, whereupon a welding seam point (3.1, . . . , 3.n-1) forms an inner link between the plastic parts (1.1., . . . , 1.n) upon cooling. The energy-converting media can be chosen according to type, coating thickness, etc., so that a melt is obtained upon simultaneous irradiation with two or more laser beams. In another embodiment of the inventive method, a laser beam (11.1) having a wavelength of ?1 is used, the light thereof being partially absorbed in a first boundary layer (2.

Abstract: Antistatic fabric for flexible containers for bulk material that includes electrically non-conducting threads and static dissipative, special permanent antistatic threads. The static dissipative, special permanent antistatic threads are made of a thermoplastic synthetic with an additive mixed in that increases the conductivity. The static dissipative, special permanent antistatic thread is shaped like a small band or tape with an approximately rectangular cross-section or a multifilament of very thin filaments.

Abstract: A flexible shipping container (100), particularly for bulk material, is disclosed. The container consists of a cylindrical or cube-shaped carrying bag (2) made of a fabric of synthetic fiber or synthetic thread. On one upper side panel edge (4), the carrying sack is provided with a lid section (5), where the lid section (5) is connected to the carrying sack (2) with a zipper (7) at least around a portion of its circumference. In this manner, it is possible to open or remove entirely the lid section simply by pulling open the zipper. The interior of the carrying sack is then freely accessible for cleaning or repair work, or to insert an inner sack made of synthetic foil. After the work is finished, the lid section is reconnected to the carrying sack using the zipper and the container is ready for renewed use.

Abstract: PCT Pub. No. WO96/32240 PCT Pub. Date Oct. 17, 1996A method for preparing high-strength biodegradable woven or knit webs or mesh hose from biodegradable foil material is provided. The method utilizes a biodegradable foil material made of a modified starch and having a softening point between 60.degree. C. and 80.degree. C. and a thickness of between 10 .mu.m and 350 .mu.m. The method includes the steps of subjecting the foil material to a relative humidity between 45% and 65%, slitting the foil material into small foil strips, stretching the small foil strips while heating the strips to between 30.degree. C. to 70.degree. C., and stretching at a stretching ratio between 1:3 to 1:10, at a relative humidity of between 45% and 65%. The stretched small foil strips are cooled to room temperature, and processed into a woven or knit web or mesh hose.

Abstract: The invention relates to a high-strength synthetic fiber fabric which contains electrically conductive threads in addition to electrically nonconducting threads. The electrically conductive threads contain electrically conductive carbon dispersed in them. The electrically conductive threads consist of a polyolefin and are incorporated both in the warp and in the filling of the fabric. The invention also relates to a bulk container and a strap which have been made from the synthetic fiber fabric according to the invention. The fabric and the objects manufactured therefrom have excellent mechanical strength and a reliable dissipation of static electricity.
