text: " Crocheted textiles receive scarce scientific study and
are at present not produced in automatized industrial scale. Computer-aided modelling
and simulation offer capabilities for investigating possible technical fields
of application. In this context a novel approach for modelling crocheted textiles
consisting of chains, slip stitches and single crochets using a topology based
and parameterized key point representation at the meso scale is proposed. According
to the stitch size, yarn diameter and pattern spline interpolated models, which
are free of interpenetrations up to approximately a 1/10 ratio of yarn diameter
to stitch size, are generated by a developed Python program and software from
the company TexMind. The models are suitable for finite element method (FEM) applications
with LS-DYNA with which the mechanical properties of crocheted textiles can be
studied. Exemplary simulations show anisotropic properties and homogeneous distribution
of stresses in a crocheted textile. Due to the computationally simple and flexible
modelling the presented approach may serve as a tool for designing planar crocheted
textiles. This allows for estimation of the required yarn length and offers the
prediction capabilities of simple and fast FEM simulations based on beam elements.\r\n

text: " Polyacrylonitrile can be used as a base material for thermochemical
conversion into carbon. Especially nanofiber mats, produced by electrospinning,
are of interest to create carbon nanofibers. Optimal stabilization and carbonization
parameters, however, strongly depend on the spatial features of the original material.
While differences between nano- and microfibers are well known, this paper shows
that depending on the electrospinning method and the solvent used, considerable
differences between various nanofiber mats have to be taken into account for the
optimization of the stabilization conditions. Here, we examine for the first time
polyacrylonitrile nanofiber mats, electrospun with wire electrospinning from the
low-toxic dimethyl sulfoxide as a solvent, instead of the typically used needle
electrospinning from the toxic dimethylformamide. Additionally, we used inexpensive
polyacrylonitrile from knitting yarn instead of highly specialized material, tailored
for carbonization. Our results show that by carefully controlling the maximum
stabilization temperature and especially the heating rate, fully stabilized polyacrylonitrile
fibers without undesired interconnections can be created as precursors for carbonization.\r\n

text: " Textile fabrics are often subject to abrasion, starting
from exposed parts of garments to a variety of technical textiles. Abrasion protection
by usual coatings, however, can significantly decrease the water vapor transport
through a fabric which is often not desired, especially in the case of garments.
In our paper, we report on an approach to combine increased abrasion resistance
with sufficient water vapor transport properties. For this, different polymers
(poly(methyl methacrylate), acrylonitrile butadiene styrene, or amorphous polyamides)
were coated on cotton and polyester woven fabrics. The results of abrasion tests
against sandpaper show significantly increased abrasion resistance. The absolute
evaporation resistance, measured by a Permetest testing device, was only slightly
increased up to values still acceptable for typical garments. Images of all coatings
by helium ion microscopy deliver an explanation for the measuring results. Polymer
coatings on the polyester fabric resulted in a slight reduction of the hydrophobicity,
while coating the cotton fabric severely increased the contact angles of the originally
superhydrophilic material.\r\n "
