The impact of stitch density and seam class on the moisture management properties of seams was investigated in this study. A lapped seam (Class 2) using a Flat Lock Stitch class ASTM 607 and a super imposed seam (Class 1) using an Overlock Stitch Class ASTM 514 were constructed with four different stitch densities – SPI 10, SPI 14, SPI 18 and SPI 22, and the moisture management properties of seamed fabric in terms of the spreading speed, area of spreading, absorption time, wetting time, one-way transport index and overall moisture management capability (OMMC) on the seam line were investigated. It was observed from the results that the seams made with low stitch density show better moisture management capability, and the lapped seam exhibits better moisture management capability when compared to the superimposed seam.

W pracy zbadano wpływ gęstości i klasy ściegu na właściwości odprowadzania wilgoci szwów. Zastosowano: szew zakładkowy (klasa 2) – Flat Lock Stitch class ASTM 607 i szew super narzucony (klasa 1) – Overlock Stitch Class ASTM 514. Szwy miały cztery różne gęstości ściegów: SPI 10, SPI 14, SPI 18 i SPI 22. Zbadano właściwości zarządzania wilgocią zszytej tkaniny pod względem szybkości rozprowadzania, obszaru rozprowadzania, czasu wchłaniania, czasu zwilżania, wskaźnika transportu w jedną stronę oraz ogólnej zdolności zarządzania wilgocią (OMMC) na linii szwu. Na podstawie wyników zaobserwowano, że szwy wykonane z małą gęstością ściegu wykazują lepszą zdolność odprowadzania wilgoci, a szew zakładkowy wykazuje lepszą zdolność odprowadzania wilgoci w porównaniu ze szwem nałożonym.

Purpose: Flexor injuries are most common in the hand and require special attention and experience from the surgeon. Both quality and technique affect the stability of the suture. The selection of the optimum method will influence the process of rehabilitation. The aim of this study was to compare three different suture techniques based on the strength, depending on the method of breakage, i.e., axial or pulley load. Methods: The study was divided into six sessions. The research material was dissected deep flexor porcine tendons. Three types of stitches were used: the modified Kessler suture with an additional running suture, the cruciate four-strand suture with an additional running suture and the multistrand running suture. We obtained 120 sutures, 40 for each technique. Breaking strength was assessed using a tensile machine in two ways, i.e., axial or pulley load, with 20 sutures per group. Results: The strongest suture for both axial and pulley load was the cruciate four-strand suture. Between the multistrand running suture and the modified Kessler suture, there was no statistically significant difference in the strength of breaking for both axial and pulley load. Comparing the two ways of breaking, there was no statistically significant difference in the strength of the suture. Conclusions: The multistrand running locking suture is a good alternative to widely used core sutures. It not only provides the same strength as other techniques examined by us but also reduces the procedure time and trauma to the tips of the tendon.

There are presented results of drape measurement of three upper fabrics and two linings without any seam and with two kinds of seam introduced in three directions: warp, weft and at angle 45°. Drape was assessed on the Cusick’s Drape Tester. Any trend was observed for the results of drape of fabrics with the seam and without, the behavior of fabrics with the introduced seam was different and dependent on a kind of seam and it direction.

Dokonano analizy porównawczej wskaźnika przesuwalności nitek w szwie wg normy PN-76/P-04616 i norm PN-EN ISO 13936-1:2005 oraz PN-EN ISO 13936-2:2005, które ją zastąpiły. Badania zostały przeprowadzone na trzech grupach tkanin, charakteryzujących się splotem płóciennym i masą powierzchniową w zakresie 90-150 g/m2. Przeprowadzono ocenę statystyczną uzyskanych wyników badań.

In the paper there are presented results of a drape coefficient measured according to PN-73/P-04736. The authors examined the behaviour under its gravity of fabrics without a seam or with a seam in a warp, weft direction or diagonal direction. Seams were done according to PN-83/P-84501. The measurements were carried out for different fabrics. On the basis of obtained results, which are presented in tables and figures the influence of raw material, weave and a kind of seam and seam direction on a fabric drapeability was discussed.
