  • Color Fastness Testing Of Fabric

    Color Fastness Testing Of Fabric

    17 Jul, 2018

    The color fastness of fabrics is the degree of color fading of dyed or printed fabrics are affected by external factors (including extrusion, friction, washing, raining, exposure, light, seawater impregnation, saliva impregnation, water stains, sweat stain) is the important indicator of textile during processing or using . the product has good color fastness, it is not easy to lose color during processing or using, otherwise there will be some states such as dorp or stains , causing a lot of troubles. The most common problem of textile color fastness as follow: 1. Light fastness is not up to the standard the clothing during wearing , the color of the part of the clothing exposed to the sun begins to lighten or change color (usually  the back and shoulders ), the color is constant or light without exposure or less exposure. People don’t use products with different color depths. 2. The color fastness of washing, soaping, dry cleaning is not up to the standard the cloths are faded after washing.silk, wool,and cotton are mostly prone to such problems. 3. The color fastness to rubbing is not up to the standard during using, there are the different degree of the color color fading, the most easily color fading parts are jackets, sleeves, elbows, collars, underarms, and pants for hips and knees.

  • Research on Testing of Fabric Tear Performance

    Research on Testing of Fabric Tear Performance

    12 Jul, 2018

    General The phenomenon of the fabric being pulled apart under such concentrated loads is often referred to as tearing. The tear strength of a fabric is an important indicator of the quality of textiles. The instrument used to measure this indicator is called Elmendorf Tearing Tester.     Calculation principle: The tear strength measured by Elmendorf Tearing Tester was calculated from the work consumed when the sample was torn, and it can be said to be the average strength of the fabric tear. The work consumed during the tearing of the sample is the conversion of the potential energy of pendulum hammer. The potential energy consumed by the pendulum hammer before and after work can be divided into two parts: the work consumed during the tearing of the sample and the work consumed by all other resistances in the process. The work consumed for tearing the specimen is the product of the average tearing force and the work stroke; the work consumed by the resistance is the product of these resistance moments and the swing angle of the pendulum hammer. As shown in the figure, the solid line is the initial state, and the dotted line is the position at the end of the work.   The formula for the principle of action is                  m g ( h1 - h2 ) = FS +Mα                Or  m gΔh = FS +Mα (1)                  In the formula:                  m--- Pendulum hammer mass, kg;                g--- Gravity acceleration, m / s2 ;                Δh--- Height difference of gravitational center of the pendulum hammer before and after work, m;                F --- Average tearing force of sample, N;                S --- work stroke of tearing the sample, m;                M --- Resistance moment, N·m;                α--- Pendulum hammer rotation angle. Machine recommendation:  AG11 Elmendorf Tearing Tester It is used to measure the tear strength of materials such as fabric, paper, plastic cloth, film, electrical tape, and metal foil.

  • Wear Abrasion Resistance-Martindale Abrasion Tester

    Wear Abrasion Resistance-Martindale Abrasion Tester

    25 Apr, 2018

    Wear resistance is an important index of textile product quality, directly effect the durability of textile product. Evaluate method of Fabric abrasion resistance ability: 1.Determination of specimen breakage Sample under a certain load and plane motion in Lissajous curve abrasion with abrasive, determine the wear-resisting ability of fabric as the Total abrasion times when sample damage. 2.Determination of mass loss Sample under a certain load and plane motion in Lissajous curve abrasion with abrasive, determine the wear-resisting ability of fabric as the mass lost of sample after abrasion a certain times. 3.Assessment of appearance changes: Sample under a certain load and plane motion in Lissajous curve abrasion with abrasive, determine the wear-resisting ability of fabric as the appearance changes of the sample. Instruments recommend: AG04 Martindale Abrasion And Pilling Tester -AVENO Martindale Abrasion and Pilling Tester is used to determin the abrasion resistance, pilling performance and surface changes of woven fabrics, knitted fabrics, pile fabrics, coated fabrics and non-woven fabrics.

How to set the test method of Hydrostatic Head Pressure Tester?

Hydrostatic Head Pressure Tester is used to determine the water penetration resistance of all kinds of fabrics used for waterproofing, such as canvas, coating cloth, tent cloth, tarpaulin, rainproof clothing and geotextile materials, etc. According to the required experimental method, the parameters of the working mode such as pressurization, constant pressure timing, constant pressure timing, flexural experiment, water leakage and water leakage can be set. After each setting is completed, click to confirm and enter the working interface for experimental test. [P Rise]: Set the test sample, pressure unit, sample area, and pressurization rate. [Const P & Timing]: Set the test sample, pressure unit, sample area, pressurization rate, and end point pressure. [Const P & Time]: Set the pressure unit, sample area, pressurization rate, end point pressure, and constant pressure time. [Water Penetration]: Set the pressure unit, sample area, end point pressure, and pressure rate. [Fatigue]: Set the pressure unit, sample area, end point pressure, pressurization rate, constant pressure time, and experimental period.

Operate Steps of Electronic Crockmeter
Operate Steps of Electronic CrockmeterJun 17, 2019

Operate Steps of Electronic Crockmeter

1 Sample Preparation Sample and standard friction white cloth should be in such environment of constant temperature and humidity to humidify. When the sample has many kinds of colors, should make all colors rubbed. If the size of a variety of colors is large enough , should be sampled Respectively. Cutting sample, do dry friction and wet friction respectively, should be ensured to rub to all colors. If the positive and negative of specimen is made up of different material , colors. So the both positive and negative need to do friction colo fastness test. Doing dry and wet fastness of friction should not be repeated in the same part in the specimen. 2 Dry Friction Flatly put sample on the friction apparatus placing sandpaper, make the length of the specimen is in line with the direction of the moning track of the equipment, and fix sample on the pressuring plate, the folder should be flat. Standard friction small white cloth fix on the friction head, clamp it tightly with spring clamp, lightly  place friction head on the specimen. Ensure the specimen without sliding or wrinking when rubs Place friction head on the specimen, connect to he power, open the POWER button, set the times of testing. Press START button to begin the test, when the tests reaches the setting value, the instrument automatically stops. Remove the standard white cotton cloth , going to rate contrasting to color cards. 3 Wet Friction Completely soak standard friction small white cloth in distilled water. After removing, clamp in the filter paper to extrude in order to have a certain degree of water content. The remaining steps is same as the dry friction test.
