Description
Technical field:
The invention belongs to weaving precision measuring instrument technical field, relate to hanger weight, dangle and the measuring method and the device of arch camber form and performance.Can be applicable to the measurement of yarn, rope, fabric feature and style, and the evaluation of the clothes snugness of fit and the aesthetic feeling of dangling.
Background technology:
The drapability of fabric and yarn and arch camber play crucial effects to shaping processing, dress and the use of textile and the concordance of moulding, both influenced the softness of underwear, next to the shin and comfort property, and well-pressed, crease-resistant, the conformal of coat and visual sense of beauty; Influence the usabilities under stressed effect such as overcanopy, sail, airbag, curtain, curtain again, and the moulding and the folding and unfolding performance of fabric such as parachute, tent.
Therefore, make the fabric and the demand that satisfies multi-functional textile of good appearance style, must select corresponding fabric and yarn style, comprise mechanical properties such as weight, draping property, arch camber performance and bending property, come the final textile of production and processing.
Method of testing to fabric fall can be divided into two big classes at present: a class is called umbrella formula sciagraphy; One class is the unidirectional method of dangling.Umbrella formula sciagraphy produces sagging principle based on fabric and studies the draping property of fabric under the deadweight effect, though this class research have bibliographical information (Xu Jun, Mu Yao. fabric umbrella formula is dangled rotational speed to the sex research of dangling. Xibei Textile Engineering College's journal, 2001,15 (2), 122～125; Guo Yongping, Li Changlong, Li Ruqin. fabric fall theory and Study on Test Method summary. China Textile University's journal, 1999,25 (3), 94～98) and patented claim (Zhou Hua, Shen Yi, Yao Yuefei. the fabric fall tester. Chinese patent: ZL97224718.1,1999; Zhao Wen, Wang Xiyuan, Wang Panwen. the computer multifunctional fabric style tester that dangles. Chinese patent: ZL89205920.6,1990), but the drapability method of testing in report and the patent is, be pressed on the cylindrical support platform by the circular fabric sample with certain area, because of the projected area of the sagging generation of conducting oneself with dignity characterizes the draping property of fabric, its condition all is that dangling under umbrella formula condition is shaped and the outward appearance visual effect.Therefore crystallized ability, anti-arch camber ability, drapability and the elegant sense of difficult reflection fabric on a certain specific direction of this method, and in textile is shaped processing and clothes manufacturing process the dangling of textile single direction, elegant and arch camber performance to the processing of textile, the orientation of lining, the modeling effect decisive role of clothes.
The unidirectional method of dangling also has bibliographical information (Peirce F.T., J.Text.Inst., 1926,17, T355-368; P.Grosbergand N.M.Swani.The Mechanical Properties of Woven Fabrics Part IV:The Determinationof the Bending Rigidity and Frictional Restraint in Woven Fabrics.Textile Res.J, 1966,338-345; CSIRO Australia.Fast Instruction Manual, 1994), this method is based on the crooked principle of semi-girder, only is used for static state and tests the draping property that the bending length of bend specimen characterizes fabric indirectly down, and do not consider the dynamic unidirectional overhanging feature of fabric down.
Because the unidirectional draping property of the arch camber performance of fabric and fabric plays important effect to the wearability of fabric and the aesthetic feeling performance of clothes, therefore this patent is also at present to relevant bibliographical information (the P.Grosberg and N.M.Swani.The Mechanical Properties of Woven Fabrics PartIII:The Buckling of Woven Fabrics.Textile Res.J. of the method for testing of fabric arch camber, 1966,332-338; T.G.Clapp and H.Peng.Buckling of Wovens Fabrics Part III:Experimental Validation of Theoretical Models.Textile Res.J., 1990,641-645), design one device that the drapability and the arch camber property testing of fabric can be integrated in one.
Therefore, all be necessary to study the drapability and the arch camber that integrate hanger in practicality and the theoretical research and measure, dynamic and static performance measurement is in the measuring method and the device of one.Simultaneously former state is obtained the indexs such as weight, bending stiffness of hanger in situ.This not only can be accurately, measure dexterously, and can be this type of measurement new method is provided.
