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...

The light fastness refers to the degree of lightfastness of the dyed fabric, that is, the degree of discoloration and discoloration of the dyed fabric under the illumination of sunlight or artificial light sources.Sunlight fading is a relatively complicated process. Under the illumination of light, the dye absorbs light energy, and the molecules are decomposed or rearranged to cause discoloration and discoloration. The fading mechanism is different, such as the fading of azo dyes on cellulose fibers, mainly due to the oxidation of dyes by air under the illumination of light, and its fading on protein fibers is often the result of reduction. According to international standards, the light fastness is divided into 8 grades, the lowest grade 1 is equivalent to fading after exposure to sunlight for 3 hours; the highest grade 8 is equivalent to fading at 384 h after exposure to sunlight. The evaluation method is based on the comparison of the blue wool standard. The standard is a wool fabric dyed with 8 different light fastness blue dyes, and the degree of solarization between them is geometrically spaced. That is, level 2 sun 57 h, level 3 sun 112 h, level 4 sun 166 h, level 5 sun 220 h, level 6 sun 275 h, 7 level sun 329 h. Under normal circumstances, the light fastness can reach 4, and the special requirements for high light fastness can reach 5 levels. However, in the actual test, since the intensity of the sunlight is unstable, the test results are also different, so the artificial light source (the xenon arc lamp, the carbon arc lamp) is used to test the light fastness. The general methods are now GB/T8427-1998 "Test Method for Xenon Arc Lamps"; ISO 105-B01-1994 "Textile Fastness Test Part B01: Light Fastness", ISO 105-B02-1994 "Textile Colors" Fastness test Part B02: Resistance to artificial light fastness Xenon arc lamp fading test, ISO 105-B05-1993 "Texture fastness test of textiles Part B05: Detection and evaluation of photochromism"; AATCC139-2000 "Lightfastness" Color fastness: detection of photochromism, AATCC 169-2003 "Textile weatherability: Xenon arc lamp irradiation"; JIS L 0841-2004 "Sunlight fastness test method", JIS L 0842-2004 Test method for dyeing fastness of ultraviolet carbon arc light, JIS L 0842-1998 "Test method for dyeing fastness of xenon arc resistance".
