Shrinkage of warp and weft is one of the important parameters of fabric structure, which is related to many physical and mechanical properties, appearance, weaving process, analysis and design of fabric.Over the years for this problem, many researchers conducted many studies at home and abroad, in order to calculate shrinkage and the length of the yarn and fabric, many research workers according to the shape of the yarn fabric, assuming that the many models, including the tangent, playground tangent, ellipse tangent, sine curve, exponential function and some mechanical model.
The length and shrinkage of the inner yarn of the fabric are usually determined by hand pulling method and constant weight method. The accuracy of the two methods, especially the hand pulling method, is not accurate enough. In order to determine the length and shrinkage of the yarn more accurately, the tensile method is used.The principle is to remove the yarn from a known fabric strip, straighten it under tension, and measure its length in this state, expressed as shrinkage.Tension is selected according to yarn type and line density.
Our new yarn count measuring instrument can accurately measure shrinkage ratio.
scope of application :
It is mainly used to measure the length of wool woven fabric, knitted fabric and yarn before weaving, so as to calculate its linear density and braiding density coefficient.And measure the elasticity of elastic yarn and bulked yarn.
standard :
GBT 29256.3-2012 FZ/T01091 FZ/T01093 ISO7211 BS2863/2865/2866 IWSTM169
instrument characteristics :
1, the instrument adopts microcomputer control test force value, stable and reliable.
2. The color touch screen is easy to operate and can be input to automatically calculate the shrinkage ratio.
