Chan et al. / Journal of Materialswas quite large, ranging from to gf cm2/cm.represents the hysteresis of the bending moment. It is aof recovery from bending deformations. A lower value2HB is supposed to be better. For this factor, sample 4, a peachfabric was demonstrated to be the best with a 2HB value gf cm/cm while sample 9 showed the least ability ofvery from bending deformation as shown by its 2HB valuelow as .Shear propertyWhenever bending occurs in more than one direction, so thatfabric is subject to double curvature, shear deformations offabric are involved. As revealed by its definition, shear propis highly related to fabric bending property. Shear propertyconjunction with bending property is thus a good indicationthe ability of a fabric to drape.Shear deformation is very mon during wearing processthe fabric needs to be stretched or sheared to a more or lessgree so as to conform to the new gesture of body movement.the makingup of a garment, shear deformation is alsofor an intended garment shape. Shear rigidity Gvides a measure of the resistance to rotational movement ofwarp and weft threads within a fabric when subjected to lowvels of shear deformation. The lower the value of G, the morethe fabric will conform to threedimensional curvatures.the shear rigidity is not enough, fabric distortion will easily. So does the skewing or bowing during handling, layingand sewing. On the other hand, too high shear rigidity mightbring problem to form, mould, or shape, especially at theve head.For the present study, the value of G exhibited a big range,arying from gf/cm degree, the data recorded on samplea polyester crepe weave fabric, to gf/cm degree, thevalue of sample 9, a cotton twill weave fabric. 2HG andthe hysteresis of shear force at ?and 5?, are twomeasures of the shear property of a fabric. Like 2HB,lower the 2HG and 2HG5, the better the recovery from shearFor this aspect, sample 9 demonstrated the worstof recovery from shear deformation with a 2HG value gf/cm and 2HG5 value of gf/cm while sample 5xhibited the best recovery from shear deformation with a 2HGalue of gf/cm and 2HG5 value of gf/cm.CompressionFabric pression is one of the most important factors whenfabric’s mechanical properties since it is highly relatedfabric handle, . fabric softness and fullness, and fabric’s surace smoothness. Especially, this property might even influencethermal property of a fabric. For example, when a fabric isa subsequent drop in its thermal insulation will beas well due to the loss of still air entrapped in the fabric.property can be influenced in many ways. Genspeaking, this property can reflect the integrated effectfabric structure like yarn crimp level and thickness, the confiber and/or yarn surface property and lateral presbelobelo.tohigherdue.vforsingleKESthroughandapparatusvthestifstiftheandthepropertiesapressionalTechnology 174 (2020) 183–189property. Three indices can be used as a measure of property, LC, the linearity of pression–thicknesse, WC, the pressional energy per unit area, and the lastis RC, the pressional resilience, which reflects the abilof a fabric’s recovering from pressional deformation.For the present study, sample 10 exhibited the best presrecovery ability with a RC value of %, followed by1, whose RC value was %. Sample 5 ranked thewith a RC value of %. The reason why these threeabrics enjoy a high RC value is that they are all made of eitheror partially wool fibers, a high resilient fiber. In contrastthis, fabrics containing cotton fibers presented the leastto recover from pressional deformation like samplewhose RC value is %, sample 11, %, and sample%. The LC value of the present study ranged from 1) to (sample 6), and the WC value changed from(sample 1) to (sample 8).Surface propertyApparently, fabric handle bears a close relationship with theace property of the fabric. Three parameters are used asof fabric surface property. They are MIU, coefficientfriction, MMD, a measure of the variation of the MIU, anda measure of geometrical roughness.MIU is mainly governed by the contact area and type ofve. The greater the area of contact, the higher the MIU value.the present study, the largest coefficient of friction was foundsample 4 with a MIU value of . Samples 5 and 6 rankedsecond with a same value of . All the others’ MIU isw . Most of the MMD values of the tested fabrics werew except for sample 12 with a MMD value as high asThe geometrical roughness of sample 12 demonstratedbe the most prominent. Generally, a plain weave exhibits ageometrical roughness by parison with twil
