Tearing properties of upholstery flocked fabrics

Abstract

We have studied the tearing strength of substrate woven fabric, substrate with adhesive, flocked fabric and washed flocked fabric on dry and wet conditions. The tensile strength of the rubbed flocked fabric and rubbed washed flocked fabrics in dry and wet conditions were also researched, and a statistical model was developed for the analysis of the tearing behavior of these fabric forms. Warp and weft tearing strengths of rubbed flocked fabric and rubbed washed flocked fabric in wet conditions were slightly higher than those in dry conditions. The reason was partly the high wet strength characteristic of cotton fiber and partly the lubrication effect of acrylic adhesive under wet conditions. Although the weft density of the substrate fabric was around half of its warp density, there was a small difference between warp and weft tearing strengths of dry and wet states of rubbed flocked fabric. This was attributed to the dense structure having less free space and less ultimate deformation potential and ultimately reducing the tearing strength. When the stroke number increased, the warp and weft tearing strengths of dry and wet states of rubbed flocked fabric generally decreased. It was also found that the stroke number of wet rubbed flocked fabric and rubbed washed flocked fabric was low in comparison with stroke number of dry rubbed flocked fabric and rubbed washed flocked fabric. The reason was that the wet acrylic adhesive had poor properties. The results from the regression model were compared with the measured values mainly by the mean absolute percent error parameter which enables us to conclude that the developed regression equations explain the tearing strength of flocked fabrics.

Study on the tearing behaviour of woven shirting fabrics – the effect of yarn and fabric properties

“…Since the static tearing is a common reason of fabric rupture during use, Witkowska and Frydrych (2008) tried to interpret the tear strength in fabric quality evaluation (Witkowska and Frydrych, 2008). The effect of moisture on the tear strength of the flocked fabric was examined by Bilisik et al (2011), through measuring tear resistance of flocked fabric in dry and wet condition (Bilisk et al , 2011). In a research by Triki et al (2011), the tearing resistance of plain and twill woven fabric were assessed by tongue and tensile central crack tear tests method.…”

“…Ambroziak, 28 Kato 29 and Klosowski 30 performed uniaxial and biaxial tensile tests on PTFE and PVC coated fabrics. Also, reported the tearing performance of coated fabrics (automobile seat covers), 31 upholstery flocked fabrics 32 and cotton. 33…”

Flok Üretimi, Karşılaşılan Hatalar ve Çözüm Önerileri

“…Floklu kumaşların sürtme direncinin, flok lif yoğunluğunun azalması ve flok lif uzunluğunun artması ile arttığı saptanmıştır [4]. Otomotiv koltuk kılıfı alanında kullanılmak üzere üretilen floklu kumaşların mekanik karakterizasyonu ve sürtme sonrası kopma/uzama değerleri, ayrıca döşemelik floklu kumaşlar için taşıyıcı kumaş, yapıştırıcı kaplı taşıyıcı kumaş ve yıkanmış floklu kumaşların yaş ve kuru koşullarda yırtılma mukavemetleri ayrıntılı olarak incelenmiş ve matematiksel modeller öne sürülmüştür [5][6][7].…”
