The color and color of the dyed products are different,and there are two symptoms( in this problem): One is batch chromatic aberration:In the same batch, there is a color difference between the case and the case, between the parts, between the bag and the bag, and between the piece and the piece. The other also is batch chromatic aberration(but there's a difference):In the same batch of products, there is a color difference in the left or in the front and back, or in the front and back. The fiber composition of all kinds of fabrics is different, the kinds of dyes and the process equipment used in dyeing are different, and there are different requirements and characteristics in dyeing and processing. The causes and manifestations of defects are different. Color aberration is varied in appearance, but the main reasons are as follows: First is uneven distribution of dyes on fabric(including fabric factor,absorbent factor,pre-drying factor); Second is dyestuffs have a different degree of fixation on the fabric;Last is dye color variation(including predyed factors,dyeing factor,post-dye factors and soaping.) The product has color difference that bring the bad shopping experience for consumer and the bad influence for brand public praise.Due to reduce this negative effect for minimum level,we should launch a strict test about color difference when the product is finished. GESTER is just for professional testing,there are some testing machine from us will introduce for you to improve the color difference and the quality of product.as below: 1、Electronic AATCC Rotary Vertical Crockmeter GT-D45B 2、Lab winch yarn dyeing machine GT-D26 3、Room Temperature Dyeing Machine GT-D16 4、Laboratory Dyeing Padder GT-D19B  

The colour fastness of textile is meaning the fading degree of dyed or printed fabric that undergo the effect of external factors (including extrusion, friction, washing, rain shower, exposure, light, seawater impregnation, saliva impregnation, water stains, sweat stains, etc.)during the using or process,it is a important index of textile.The product has good colour fastness and it not easy to lose color during processing or using;otherwise it will appear some states like drop or stain and cause a lot of trouble. The most conventional problem of colour fastness of textile as below: 1、Sun fastness is not up to standard: The clothing during the dressing ,the color of the part of clothing that more exposed to sunlight begins shallow or discolored (usually is the back and shoulders), where there is no or less exposure, the color is constant or light. People will not use the product that the color is different in depth. 2、Colour fastness to washing, soaping and dry cleaning is not up to standard:Clothing fading after washing.The silk,wool,cotton clothing is easy to have such problems mostly.   3、Color fastness to friction is not up to standard:Textile during using,there is different fading degree in different part that has different degrees.And the part most easy to fading is jacket, sleeve, elbow, collar, and armpit,also the buttocks and knees of the trousers.      The product has poor color fastness that brings the bad shopping experience for consumer and the bad influence for brand public praise.Due to reduce this negative effect for minimum level,we should launch a strict test about color fastness when the product is finished. GESTER is a company specialized in textile testing equipment,there are some Colour fastness testers from us will introduce for you to strength the color fastness and improve the quality of product ,as below: 1、GT-D07  Colour Fastness & Fabric Washing Fastness Tester 2、GT-D09  Fabric Color Fastness To Perspirometer 3、GT-D02  Environment Xenon Weathering Test Chambers 4、GT-D04  AATCC Electronic Crock Meter

Textile Sample Color Fastness To Rubbing  The whole process of color fastness to rubbing. Principle: This test is designed to determine the degree of color which may be transferred from the surface of a colored fabric to a specify test cloth for rubbing (which could be dry and Wet). Equipment that needed for measurement: 1. Crock Meter GT-D04. 2. Cotton Rubbing Cotton. 3. Grey Scale 4. Stop Watch 5. Color Matching Cabinet GT-D08. Size of Fabric: You will need to have 14 Cm * 5 Cm pieces of textile fabric sample (one warp direction/wale direction and other weft/course direction). Test Procedure of Color Fastness To Rubbing: a)Lock the test specimen (textile sample) onto the base of the crock meter. b)Using the spinal clip, set 5 Cm * 5Cm of the white cotton fabric to the finger of the crock meter. c)Lower the covered finger on the test sample. d)Turn hand crank at the rate of the one turn per second. e)Remove the white rubbing test cloth and e valuate with grey scale. Evaluation In this stage compare the contrast between the treated and untreated white rubbing cloth with grey scale and rated 1 to 5.

Crockmeter rubbing fastness tester, repair the damaged rubbing finger, clip and abrasive paper. Accidental damage to the rubbing finger, spiral clip or abrasive paper should be repaired as follows: neatly renew the abrasive paper; bend the clip further open or shut around a rod slightly smaller in diameter than the crock peg; resurface the finger by movement on an extra piece of fine emery cloth in a manner simulating regular use.

Snap Tester, to determine the holding or breaking strength of prong-ring attached snap fasteners onto garments or toys, also as a Push Pull Tester applies for compression and tensile pull testing of small samples. Application Snap Tester (Button Snap Pull Tester), to determine the holding or breaking strength of prong-ring attached snap fasteners onto garments or toys, also as a Push Pull Tester for compression and tensile testing of small samples(special attachments are available). Our snap tester consists of an upper snap clamp, a lower fabric clamp and force gauge mounted on a stand, a hand wheel on the bottom of snap tester which allows fine control with convenient operation. The snap component is gripped by the Upper Snap Clamp and the garment is fixed to the lower Fabric Clamp. By turning the hand wheel, The operator can apply a specific force and the holding force or the breaking strength can be recorded. The capability of the snap tester can be enhanced with clamps & accessories for testing of other Snaps, Jean Buttons, Four Hole Buttons & Garments Accessories such as Zippers, Bows, Appliqué, Toggles, Hooks/Bars, and D-Rings, amongst others.
