Sažetak
Woven fabric abrasion is the mechanical destruction of fabric components by rubbing against another surface. This occurs during the process of wearing, cleaning or washing. It results in the loss of fabric characteristics, such as strength, but also affects the appearance of the fabric which is directly related to the usability of the material. One of the results of fabric abrasion is the gradual removal of fibers from the yarn. Therefore, the factors that affect the cohesion of the yarn will affect its abrasion resistance. The flotation length in fabrics can affect their abrasion resistance. For example, fabrics woven in twill weave will have better abrasion resistance than the fabrics woven in satin weave, while the fabrics woven in plain weave will have better abrasion resistance than the fabric in twill weave. A number of test procedures and appropriate devices have been developed for testing fabric abrasion resistance. These are generally classified according to the method of performing the relative movement of the tested sample and the abrasive part, which results in the abrasion method. The most used are flat and circular abrasion methods, testing either the entire surface or parts of the surface in constant contact with a non-preferred direction of abrasion. Recently, the largest number of abrasion resistance testing requests is carried out on a Martindale testing device. Tests performed on a Martindale device are carried out in accordance with national and international standards. In this paper, the influence of weft density on the abrasion resistance of protective fabrics for dual-use was investigated. Four fabrics were woven on a loom in plain weave with different weft densities: 19/20/21/22 threads/cm. The fabrics were woven with 50/50% Polyamide 6.6/Cotton (Cordura), fineness 30.77 tex in warp and 30/35/35% PA 6.6/Lenzing FR/M-aramid (U521) and 22/38/40% PA 6.6/Lenzing FR/M-aramid (U515) both fineness 33.3 tex in weft. The results show that the higher share of aramid and Cordura in the raw material composition of the used yarns had a positive effect on abrasion resistance, while in denser structures the weft density did not have a significant effect on abrasion resistance. The fabric with the lowest weft density (dweft = 19 threads/cm ; 22/38/40 PA 6.6 / Lenzing FR / M-aramid) has the highest resistance as the total Cordura component is higher. The same sample has lower weft consumption than the comparative (dweft = 20 threads/cm ; 30/35/35% PA 6.6 / Lenzing FR / M-aramid).
