Summary report dated 1 Oct 51 covering the quarter ending Sep 1951. Covers 4 projects.
Project 1 M: Accomplishment of continuous polymerization and spinning process for
Perlon (vacuum process). States that experts regard continuous evacuation of
a lactaa containing perlon mass as impossible for practical purposes. Project
was nevertheless undertaken to investigate all possibilities. In addition to air
discoloration, difficulties were encountered when the spongy mass under vacuum could
not be brought into the pumps. consequently hindering the course of the spinning phase.
Gives brief description of further equipment modifications under development, and
other possibilities for making the process operable. Also lab experiments are being
conducted to determine the effect of various stabilizers on the evacuation process and
its end-product.
Project 9 W: Accomplishment of perlon textile treatment. Machine has been developed
to stretch, cock, dry, and prepare and wind perlon thread. Machine is to be built
by Weinrich and. Keller, Chemnitz-Einsiedel, to be ready in a few weeks pm vided parts
and materials can be supplied. Intention is to produce perlon bristles and 'leska'
fibers (wire) from bobbin to finished product in a continuous single-stage process,
to enable experiments with coarse and fine perlon silks. (All)
Project 10 W: Development of a continuous polymerization process under pressure for
perlon. Describes difficulties in 'DK-apparatus' experiments due to slow disintegration
of clay-fragment boiling stone used in dehydration process, and consequent clogging
of pumps, valves and cocks. 'Pr*tess with pressure stage (DK-apparatus) and without
pressure stage (VK apparatus) was tried. Bosch pumps needed for pressure stage are
not manufactured in the G. so machine shop at plant developed modified version which
was satisfactory. Gives brief description of patented process fcr fiber production.
Project 11 W: Testing of new raw materials as to suitability for processing to fully
synthetic fibers. Buna Works, Schkopau, to supply polyamide raw materials.- Tests
on aminocapronitrile for pert m`production were useless because material was not
of sufficient purity for the purpose. AH-salt was tested for processing properties.
Attempted to obtain terylene polyester from dimethyl aster of terphthalic acid, and
ethylene glycol. Experiments were restricted to very small scale due to limited
available quantity of terephthalic acid, which was esterified normally with methanol
and hydrochloric acid.
Includes two diagrams, one of which is detail relative to Project 10W
