Description
Technical field
The method and apparatus that the present invention relates to detection textile product quality, particularly relates to a kind of use Light Electrical engagement means, clothing surface filoplume pliability and medicated clothing wearing comfort carries out the system and method for qualitative assessment.
Background technology
The tactile comfort of textile is one of key factor of snugness of fit affecting textile, particularly knitting hair, crudefiber crop clothes, usually bringing human body skin prodding and itching feeling or puncture sense when wearing, thus causing the sense of discomfort of physiology or psychology, and then affecting choosing of consumer. The evaluation means of existing filoplume flexibility mainly includes subjective assessment and objective examination method. Subjective assessment is to pass through human test, by participant, subjective feeling is described, the method has subjectivity, the impact of the not equal factors of ability to express different with difference neural sensitivity by different human body skin, language, the reliability of experimental data and concordance need to be investigated, therefore, the subjective evaluation result usually not comparability of different participants.
In existing fabric softness objective examination method, Chinese invention patent " method of fiber compressive bending property measurement and device " (patent of invention number: ZL200310109512.3 Authorization Notice No.: CN1236299C) discloses method and the device that a kind of fiber compressive bending property is measured, this invention adopts high accuracy Micro-force sensor, many merits upper grip and can make level and power one displacement measurement mechanism of the lower gripper composition moved both vertically, and can obtain the data such as fiber head end stress and fiber axial strain and the perverse bundle effect of simulation human body skin. Optical system is adopted to realize synchronizing the deformation under fiber axial compressive force to be converted to digital image input computing, obtain fibre fineness, grip the variablees such as length, amount of deflection and each point curvature and displacement and be controlled measuring parameter through computer real-time data collection, quickly measured strain curve and the relevant feature parameters etc. such as real-time pressure, amount of deflection, fiber bending form by theoretical model and algorithm software.

7. medicated clothing wearing comfort detection method according to claim 1, it is characterised in that further comprising the steps of:
S900: the medicated clothing Matching Relation according to preliminary election, at least one of which medicated clothing is added in the outside of medicated clothing to be measured, certain external force is applied to medicated clothing to be measured, then repeat the above steps S400 to S800, obtain touch data under different medicated clothing Matching Relation and contact morphological image data, by data analysis with compare, build the quantitative performance indications of the clothing surface filoplume pliability under different medicated clothing Matching Relation and medicated clothing wearing comfort.
8. medicated clothing wearing comfort detection method according to claim 1, it is characterised in that described step S800 includes following action:
S820: touch data processing module, according to the touch data obtained from each key position of anthropometric dummy, calculates and obtains medicated clothing under wearing effect and natural gravity effect, and clothing surface filoplume is in touch force profile produced by each key position of anthropometric dummy;
S840: the contact form optical image data that each key position of anthropometric dummy is obtained by filoplume morphological data processing module carries out graphical analysis, calculate the effective contact area obtaining clothing surface filoplume with touch force sensor, the filoplume dnesity index distribution of filoplume dnesity index and each key position of anthropometric dummy, wherein, effective contact area is defined as the real contact area of medicated clothing inner surface filoplume and touch force sensor sensing face, and filoplume dnesity index is defined as the ratio of effective contact area gross area with touch force sensor sensing face.
S860: aggregation of data analysis module calculates according to formula Pi=Fi/Si and obtains the pressure distribution that clothing surface filoplume produces at each key position of anthropometric dummy; Wherein: Pi is the pressure of key position i, Fi is the contact pressure that clothing surface filoplume produces on the touch force sensor i of key position i, and Si is effective contact area of clothing surface filoplume and touch force sensor i;
S880: clothing surface filoplume is carried out statistical analysis in touch force profile, the distribution of filoplume dnesity index and pressure distribution produced by each key position of anthropometric dummy, builds reaction clothing surface filoplume pliability and evaluate the quantitative performance indications of medicated clothing wearing comfort.
