    Abstract: A synthetic culture medium comprising a polymeric material having an apparent density of 0.01 and 0.5 and a specific surface area of between 2 and 25 m2/g, the polymeric material being in the form of an amorphous fibril. Such polymeric materials include thermoplastic polymers such as film-forming linear super polyamides, film-forming polyesters, vinly polymers, acrylonitrile base polymers, and polyolefins, the fibrils being suitable for use as a culture medium either alone or in combination with soil, sand and the like so as to provide a more readily aeratable mixture. Plant growth is improved by a process utilizing such synthetic culture medium.

    Abstract: Textile articles comprise yarns of a synthetic thermoplastic material, especially polyethylene terephthalate, in which the individual filaments comprise alternating zones of increasing and decreasing thickness, the thinner zones having the higher crystallinity index and vica versa; the filaments have a nonspiral three-dimensional crimp, and both they, and the yarn comprising them, have a high apparent volume. The yarn is made by only partially stretching the initial yarn in contact with a crack promoting agent such as an aqueous alcohol, and subsequently giving the yarn, before or after it is made up, a heat treatment while it is in a relaxed state.

    Abstract: Continuous filaments of thermoplastic material are provided wherein such filaments contain a helicoidal curling and/or a residual twist couple. The filaments have a cross section which is substantially the shape of a bean, such cross section varying slightly along the length of the filaments. The filaments are produced by a process which comprises creating an initial twist in an individual strand or in an assembly of a number of strands having a high count per strand and a small number of strands per assembly; thermally treating the twisted strands or assembly of strands; blocking such twist at a point; and separating the single strand or assembly of strands at such point and winding them up. Such a process is characterized in that the point of separation of the yarn is located immediately at the outlet of the heat treatment yarns while the yarns are still in a plastic state. The apparatus necessary for carrying out such process comprises a delivery means for providing the yarn by unwinding, means for separating the strands or assembly of strands, means for initiating the twisting, means for heating the twisted yarn, and means for receiving the yarn. Such apparatus can additionally contain drawing means.

    Abstract: Fancy yarns are made by subjecting yarns of a synthetic thermoplastic material, especially polyester yarns, to partial stretching, e.g. by a factor of 1.5-3.5, in contact with an aqueous lower alkanol or other crack-producing agent, followed by a heat relaxation treatment, the said or other heat treatment, or a supplementary stretch, being applied intermittently or to a continuously varying degree. The yarns obtained have a flake appearance and comprise alternating thick and thin portions, the diameters of the thick and thin portions both varying macroscopically, and the thick parts varying in diameter on the microscopic scale, the zones of smallest diameter corresponding to zones of highest crystallinity and orientation. The thin parts may vary in diameter microscopically in an analogous way but with smaller variations, or may be substantially uniform.
