    Summary: The change of thread tension in the compensating and knittingzone of knitting machine in some phases of loop formation isdiscussed. For the purposes of investigations presented in thispaper, special sensors were constructed. Powers, exerting theirinfluence in the semi-loop and loop of the plain weave in severalphases of loop formation, as well as in several cycles, weredetermined. By means of direction and tension mechanisms, thechange of the thread friction and stiffness of the thread in allits contact points was studied. The stiffness elasticity modulusas one of important parameters in this phase of investigation,was studied. Regarding the dynamism, the automatic regulation ofthe warp thread feeding was studied and the second degreedifferential equation settled. The time constant obtained, resp.the period of one cycle of loops formation was compared with theperiod of one cycle obtained by means of experiments in theprocess of knitting.

    Summary: By means of microscopic method the diameter of conventionalcotton yarn, spinned from three kinds of cotton, at the specifictensile force up to 5.5 cN/tex was measured. The decrease of yarndiameter does not occur linearry, but is more obvious up to theload of 4.5 cN/tex. Fibre counts higher than 24 mtex and lengthsover 2.9 mm exert no influence on the decrease of diameter, ifunder the yarns with the same number of twists, spinned fromthree various kinds of cotton no difference exists in the totalmedium count of 2 tex. The consequence of relatively short andcoarser fibres is a greater decrease of yarn diameter andincrease of the coefficient of variation.

    Summary: The microscopic method was used for the measurement od theelongation and diameter of combed cotton yarns 20 tex spun fromdifferent cotton types: Sudanese cotton "XG5B", Egyptian cottonGiza 75 FG and Turkish cotton white 1st class. Longitudinal,cross and volume deformation, relaxation and permanentdeformation of the yarn after relieving under the influence oftensile stress up to 5.5 cN/tex were investigated (stresses wereadjusted to the parameters of the technological process of knitfabrics production). Time influence of tensile force increaseselongation, but the yarn diameter and volume are decreased. Thedependence of relative deformations on specific stress is linearwith the correlation coefficient higher than 0.95. The relativedeformation in the cross direction is greater than deformation inlongitudinal direction. A yarn spun from shorter and coarserfibres shows a greater relative deformation in both directions.The rest of relative longitudinal deformation 12 hours afterrelaxation is from 1.6 to 2.5%, whereas the rest of crossdeformation is greater, that is from 7.4 to 10.4%.

    Summary: The contribution discusses the factors considerably influencingthe surface friction coefficient of yarns. According to thecurrent knowledges, the coefficient of good waxed yarns is until50% lower than that of not waxed yarns. For this reason, thesamples were knitted on automatic hosiery knitting machine, gaugeE 6, with waxed and not waxed cotton yarns 50 tex, under inputtensions of 5, 10 and 20 cN. The mechanical properties of yarnsare studied and the parameters of the structure of knitwearanalyzed.

    Summary: In the paper the possibility of application of mathematical model for rheological presentation of double warp-knitted fabric is investigated. This model was used for simulation of application depending on the strain in the fabrics. Elasticity of double warp knitted fabric is functionally dependent on the short intervals of strain, but during a long time permanent deformation of fabric remain. The relationship among the parameters of the mentioned rheological model depending on various loads are presented. The computed results are shown in tables and graphs.

    Summary: The influence of knitting speed, yarn type and cam form on the structure and the relaxation time of interlock knit fabric were examined. Three cotton yarns 20 tex with different caracteristics were used as samples. The samples were knitted on two interlock knitting machines with a linear cam and 48 knitting systems as well as with unlinear cam and 108 knitting systems. All most significant parameters of knit structure were analyzed. The results, which were treated by a factor plan trial, show that only the cam form has an influence on the parameters considered with the probability 0,02.

    Summary: The reasons for the dimensional instability of knit fabrics and the problems connected with the shrinkage of plain weft knit fabric after removing from the knitting machine and after washing are discussed. For this reason samples of knit fabrics of various densities were knitted. A single cotton yarn and a small diameter circular knitting machine were used. The parameters of the structure of the knit fabric as well as the properties of the yarn after knitting and after five washes were analyzed. It was found that by knitting and repeated washing the parameters of the structure of knit fabric ant the properties of yarn are changed. It was established that denser knitted goods shrink less than loosely knitted fabrics.

For knitting the core tread of the fineness 110 dtey made of polyamide filament yarn, and the combed cotton yarn should be used for the formation of pile loops. In one hour, 24 m, or 42 m2, or 12,5 kg of knitwear can be produced. Applying the tehnilogical calculation for a family plant with four machines, for the annual output 90 t of yarn is needed. The share of polyamide filament yarn is 20% and the share of cotton yarn 80%.

    Summary: Investigated is the effect of knitting speed and yarn type changes on interlock knitwear structure durin knitwear relaxation. Experiments were carried out on two cotton yarns of fineness 20 tey but with different number of twists and with different strength. Results show that horizontal and vertical density, mass 1 m2 and knitwear density coefficient change with speed increase. Results treated by experiments plan 2**3 showed that investigated parameters were considerably effected by relaxation time at assumption p=0,02 and p=0,10. In some case the effect of yarn type at assumption p=0,02 and of rotations number increase at assumption p=0,10 was established.

    Summary: As example of jumper production with three-colour jacquard nterlacing on a modern automatic flat knitting machine in a small family enterprise is given. The factors of an optimal machine choice, of production costs and profitable work as well as of the business management of such a plant are elaborated. The calculated price of a jumper is 14.70 DM or 54,40 kn. By earning 10 DM per jumper the sellingprice is 33 DEM or 120 kn. Supposing that the machine produces 10 000 pieces per year, a profit of 10 000 DM may be achieved.

    Summary: In the paper the possiblity of application of mathematical modelfor rheological presentation of double warp-knitted fabric isinvestigated. This model was used for simulation of applicationdepending on the strain in the fabrics. Elasticity of double warpknitted fabric is functionally dependent on the short intervalsof strain, but during a long time permanent deformation offabric remain. The relationship among the parameters of thementioned rheological model depending on various loads arepresented. The computed results are shown in tables and graphs.Both during knitting and use double warp-knitted fabrics tend todeformation. By applying the mathematical model descrebed anattempt was made to simulate the deformation course ofknitted-fabrics during load of different draft forces. It showedthat apply in the more complicated real situation involved in theperformance of fabrics in clothing and other end-uses, thejustifiableness of analysis during strain by various forces inviscoelastic fields have been applied. We have shown that themethod of using mathematical rheological model is suitable duringstrain caused by different loading.
