Title: Flocked yarns - produced by passing adhesive coated yarns over bed of flocked particles overlaying positive electrode the yarns forming negative one
Inventor: NADAL SANTIAGO SATORRE
IPC: D02G3/40
Filed: 1976-06-25
Abstract: Yarns or filaments are flocculated by passing adhesively coated yarns which are connected to a negative or earth potential above a single positive electrode arranged below a cloud of diaelectric flocculating particles, which in consequence of the electrostatic field produced between the yarns and electrode are attracted to the yarns. Yarns with uniformly distributed particles are produced without rotation of the yarns. Preferably the electrode is adjustable w.r.t. the yarns such that the distance is progressively reduced in the direction of movement of the yarns. Adjustment brings about differential acceleration of the flocculating particles, the acceleration being highest at the outlet from the electrostatic chamber.

Title: Single stage prodn. of polycondensation resin moulding materials - e.g. based on polyester, polyamide or aminoplast, by mixing the condensants with a water binding agent for direct use
Inventor: BOVENDER FRANZ
IPC: C08G85/00
Filed: 1976-12-22
Abstract: In a process for making moulding materials based on polycondensation resins, the raw materials used for making the resin are mixed directly, without further processing stages, with a material which takes up the water of reaction released during polycondensation. The water-binding agent may be a self-hardening material such as pozzuolana lime, hydraulic lime, Roman lime, air drying clays, tricalcium silicate, dicalciumaluminate-ferrite, silica based trass mortar, reactive clay acid pozzuolana mortars, diatomaceous earth, etc. Other suitable binding agents for the water are asd- or absorption agents such as a zeolite. The process can be used with ahe raw materials employed in the prodn. of polycondensation resins such as polyesters, polyamides, phenolic resins, aminoplasts, polysiloxanes, polysulphides, etc. The process eliminates the need for previous condensation of the raw materials, since hte condensants are mixed directly with the water-binding material to form a moulding material which is then subjected e.g. to heat and pressure to complete the resin-forming polycondensn. reaction in situ. The process is applicable to thermoplastic, thermosetting, elastomeric and fibre-forming polycondensates and the prods. can be cast, compression moulded, calendered, blow moulded thermoformed, foamed, spun, etc.
