ICI Pilling Box Tester is used to test the pilling performance of wool knitted or wool-like knitted products. The test standards are GB/T4802.3, ISO 12945.1, BS5811,  IWS TM152. ICI Pilling Box Tester Test principle: The sample tube with the test sample is placed in the pilling test chamber, the instrument is started, and the sample is flipped and rubbed in the box body. After the number of rollovers is agreed, the sample is taken out for rating. Sample preparation: (1) Pretreatment: If pretreatment is required, the sample may be washed or dry-cleaned by a method agreed by both parties. (Precaution is recommended to protect the friction surface of the pilling box and the sample tube from residual lubricant or finish on the fabric) (2) Four specimens were cut from the fabric sample, the size was 125 mm*125 mm, and another swatch of the same size was cut as a comparison sample for the rating. Two specimens were folded inward along the longitudinal direction, and two specimens were folded inward along the lateral front surface, and were sewn with a sewing machine at a distance of 12 mm from the side. (3) The suture sample is everted and the front side faces outward. Cut 6mm ports at both ends of the sample tube to remove the sewing deformation. The sample was placed on the polyurethane sample tube and fixed with PVC tape (to ensure that the ends of the polyurethane were 6 mm bare, and the length of the tape should not exceed 1.5 times the circumference of the polyurethane tube). (4) Conditioning. Experiment procedure: (1) Cleaning the pilling box (2) Put 4 sets of good sample tubes into the box, firmly close the lid, and turn the counter to the required number of rotations. (3) Preset rotation number. Number of agreements. In the absence of agreement, the coarse fabric was turned over 7200 rpm and the fine imitation fabric was turned over 14400 rpm. (4) Start the ICI Pilling Box. After the test is completed, take out the sample, go out to suture, and rate the sample.

Pilling Phenomenon: Pilling is the formation of small fiber balls (pellets) on the surface of the fabric, it is caused by wear. Pilling is the tendency of fibers to loosen from the surface of the fabric and form spherical particles of the fibers. Reason of Pilling： 1.Due to Wearing. 2.Due to friction bwtween fabric or clothing and specific parts of the body. 3.Due to soft twist of yarn. 4.Due to too much short fiber. 5.Due to the migration of fibers from the constituent yarns in the fabric. 6.Due to protruding fiber/yarn hairiness. 7.Due to the heat of thermoplastic fibers. Reduce or Minimize Pilling： 1.Through using high twist yarn. 2.Through brushing and cut the fabric surface to eliminate loose fiber ends. 3.Through to using singeing process to reduce the yarn hairness,extend fiber. 4.Through using anti-pilling technical. 5.Through special chemical treatment，Such as adhesive, anti-friction agent. 6.Reduce fiber migration through the AirJet spinning process. 7.Through increase the friction between the fiber. 8.Through increase the linear density of fiber. 9.Through using a lot of thread for per unit length. ICI Pilling Tester pilling test: 1.For this testing. Cut 4 samples which each 5inch*5inch from fabric. 2.Each back of square has marked with 12mm seam.In both two sample,The seam marked parallel to warp direction, and the other two parallel to weft irection. 3.Then fold the sample face to face and stitch the seam on the marking line. 4.It makes the seam of the two samples parallel to the warp, the seam of the two samples parallel to the weft. 5.Each sample is flipped from the inside out，Each ends cut off 6mm to eliminate any sewing distortion. 6.Then install the finished fabric tube on rubber tube.Make sure the tube’s length at each end are same. Each loose end is pasted with polyvinyl chloride (PVC) tape.Make 6mm rubber tube exposed. 7.Put the 4 samples into one pilling box. 8.Then roll the sample in a cork-linging box. 9.The normally number of revolutions is 18000 in testing, it needs 5 hours. ICI Pilling Tester Result Evaluation： 1.Remove the sample from the tube and observe with inclined lighting. 2.Then confirm the sample grade 1 to 5.

In daily experiments, when colour matching light box are used, some of them do not conform to the standard on color due to some details, which will cause adverse effects on subsequent production. Here are 7 key steps that you can take to use a colour matching light box. Key step 1: Observing the angle According to international standards, only two observation angles are available, they are: a. Zero-degree light source, 45 degree observation (0°-45°) that the light source illuminates the sample from a zero (vertical) angle of incidence, and the observer observes the sample from 45 degrees. b. Light source, 45° ramp. 45 degree light source, zero degree observation (0°-45°), in this layout, a specific 45 degree angled table (45°Fixed angle table) is used to illuminate the light source from the 45 degree, and the observer observes from zero (vertical) sample. Key step 2: 45 ° light source detection sample placement Regardless of any of the above observation methods, care must be taken to detect the sample as much as possible in the middle of the color matching booth to reduce the effects of the external light source. In addition, the most important thing is that when you need to compare the color of two or more objects, you should also try not to overlap them. It is best to place them side by side for comparison. Key step 3: environmental factors in color All external light that will have the opportunity to shine on the test sample must be avoided. If the window is in the field of view, it should also be covered with grey curtains to cover it, so it is ideal to use a color light box in the black room. Another point that is often overlooked is that no other debris can be placed on the color light box. Key Step 4: Requirements for Converting Light Sources According to the experience of daily life, in our eyes, it is like having a register. When the color changes in a very short time, we can clearly feel it. Therefore, when observing metamerism, if you want to change the light source, you must do it in an instant. Don’t be like the lighting tube we use every day. It will be high after a flash, because it will irritate the eye. Department, affecting the results of the review. Key step 5: Ability to test metamerism The so-called metamerism effect means that under a certain light source, the color displayed by the sample is the same as the requirement, but under another light source, the color difference is not acceptable. Under the D65 light source, the color is no different from the standard, but under A light, the sample color is unacceptable. Therefore, all devices for color light sources must be equipped with two or more light sources to test the same color effect. Key step 6: arrangement of the lamps Although there is no specific requirement for the arrangement of the lamps, the position of the lamps must be a uniform light source in the color matching cabinet, and must not be biased to a certain area. Key Step 7: Record the time used by the standard...

Toys Testing Equipment Nail Bed Flammable Tester is suitable for the burning performance test of cloth toys and filling materials. Perform flammability tests on solid and soft toys and fix samples. The sample to be tested is placed on the nail bed, the sample is ignited by a fire source, the combustion state of the sample is observed, and the combustion performance of the sample is evaluated.

Abrasion testing is one of the item that many materials must be tested at present. It is also an important index to determine the physical properties of materials, so as leather abrasion resistance test.The main testing methods for leather abrasion resistance are the Gakushin Abrasion Method, the TABER Abrasion Method and the Martindale Abrasion Method. Gakushin Abrasion Testing Method To testing the degree of damage and decolorization of dyed leather used in shoe upper and lining leather after friction. The test method is to wrap the dry or wet white abrasion fabric on the friction head, then repeated friction on the test piece clamped on the test bench of Gakushin Abrasion Tester. Martindale Abrasion Method This method mainly used wear resistance of textile fabric and leather materials. It specifies Martindale Abrasion Tester for testing. A circular specimen, mounted in a specimen holder and subjected a defined load, is rubbed against an standard fabric in a translation movement tracing a LIssajous figure. The evaluation of the abrasion resistance of the textile fabric or leather is determined from the inspection interval to breakdown of the specimens. Taber Abrasion Method This method is complied with ASTM D3884.The principle:A specimen is placed on a rotating platform and rubbed by the sliding rotation of two abrading wheels. One abrading wheel rubs the specimen outward the periphery and the other, inward toward the center. Thus forming a circular wear mark. After the specified number of frictions, the resistance of abrasion of the sample is evaluated by appearance. Taber Abrasion Tester can simulate the real working conditions or meet the test conditions prescribed by the standard. Also can use different abrasive medium and accessories to do the different test.

Do you have any embarrassing situation in your clothing that has been broken by a sharp object? In real life, our clothes will be broken and torn when worn, which involves the problem of strong tearing of the fabric. Then what is the tear strength? Fabric tear Fabric tearing also referred to as tearing,fabric partial yarn is subjected to a concentrated load to tear the fabric apart. During the use of the fabric, the clothes are hooked by the object, partial yarn is pulled apart by force, so that the fabric forms a strip or a triangular crack, which is also a phenomenon of breakage. Tear Strength It can reflect the degree of catalysis of the finished fabric, so the tearing strength test is performed on the resin-finished cotton fabric and the wool-formed pure or blended combed fabric. Knitted fabrics are generally not subjected to tear test except for special requirements. How to judge if the tear strength of your clothes is qualified or not? There are many methods for the tear strength test: 1. Pendulum method 2. Pants type method (including single tongue method and double tongue method) 3. Trapezoid method 4. Wing method. The most common test method is the pant-shaped single tongue tear test. And how to test it? Cut the sample as belows picture shown according the standard required. Standard require each sample cut into two test sample. One is lengthways. The other one is crosswise. Each test sample should be included at least 5 pieces. Then on test. When the stressed yarn in the sample is separated up and down gradually, the yarn that is not directly stressed begins to have some relative sliding with the stressed yarn., and gradually draws closer to form an approximate triangular area, which is usually called the stressed triangle. Due to the effect of friction resistance between the yarns, the sliding is finite, that is, the number of yarn roots under stress in the triangle is limited.In the stress triangle area, the stress on the bottom edge of the first yarn is the largest, and decreases successively. When it is sliding, the tension of the yarn increases rapidly,  the elongation of the yarn also increases sharply. When the first yarn constituting the bottom edge of the force-triangle triangle is deformed to the elongation at break, the yarn breaks. Thereby a maximum value of a certain tear load is obtained. The next yarn then begins to become the bottom edge of the force triangle, so that the yarn of the non-pull system breaks one at a time to tear the fabric. Lastly, the calculating.the electronic calculation devices divides the first peak and the last peak into four regions,exclude the first region, and records all the peaks in the rest of three region. The average value was calculated and the tear strength of this sample was recorded. (The unit is indicated by N) Testing Equipment: GT-C01-1 Universal Tensile Strength Tester (Dual Column)

Folding resistance is one of the basic mechanical properties of paper, which is used to indicate the ability of paper to resist reciprocating folding. The folding resistance of the paper is the number of folds required to measure the stretch of the paper after being stretched by a certain force and then folded back and forth until the paper breaks.It is expressed in number of times, the unit is double fold.According to the longitudinal cutting, the test result is the longitudinal folding resistance; according to the transverse cutting, the test result is the transverse folding resistance. Generally, the longitudinal folding resistance is higher than the transverse folding resistance, which is due to the arrangement of the fibers and the high bonding strength of longitudinal fibers. Folding resistance is one of the important indicators of the mechanical strength of paper and paperboard. The folding resistance is very meaningful for reflecting the performance of the paper bag and the carton lining paper. Any paper that needs to be folded frequently when used generally has strict requirements on the folding resistance.
