In dogs, injury to the cranial cruciate ligament (CCL) is commonly repaired with artificial textile materials. The dynamic mechanical behavior of this textile product must be similar to the natural CCL of the dog. Therefore, a test method has been de

Objective—To determine the in vitro structural and material properties of braided, multifilament, nonabsorbable polyester tapes, used for intra-articular stabilization of cranial cruciate ligament- (CCL-) deficient stifle joints in dogs, and compar

In air-jet weaving, weft insertion time depends on the characteristics and properties of the weft yam. Because deviations of properties within bobbins exist, a control system is sometimes required to obtain a sufficiently even arrival time of the wef

The dependence of the yarn speed on air velocity and yarn properties makes the weft insertion process in air-jet weaving complicated. The influence of the yarn properties as well as those of the production (spinning) parameters and fibre properties o

The time needed to insert 50/50 polyester/cotton yarns with a nominal count of 20 tex on air-jet looms is investigated. Because weft insertion on air-jet looms is extremely complicated, a statistical approach is followed in order to relate weft inser

This paper deals with the problem of carpet resilience which depends on pile yarn properties and carpet construction characteristics. Up to now, resilience could only be measured on the carpet itself. New methods are being developed to assess the res

Relaxation of warp yarns and fabric is one of the causes of set marks (starting places) in weaving. Loom manufacturers have developed experimental procedures to diminish these set marks, and this paper describes mathematical simulations of several su

This paper proposes a model for calculating relaxation behavior after dynamic load ing of fabric and of warp yarns. The model is based on fitting the parameters of an extended nonlinear Maxwell model to experimental data using nonlinear regression. C

After a short introduction on cumulative back-propagation neural nets, two network connfigurations are presented for fitting time functions. These configurations were used to model relaxation curves of yarns after dynamic loading. It follows that neu

A theoretical model for the description of relaxation curves after dynamic loading is presented in this paper. The model is based on a nonlinear spring placed in parallel with Maxwell elements. The obtained formula is fitted on experimental relaxatio
