Hong Yu Technology Co., Ltd. business: constant temperature and humidity testing machineTensile Testing Machinesalt spray test machine Synthetic Leather Association, or industry Bureau, so far, are not a matter of setting standards. In accordance with the following key JCSS, and then taking into account any of the largest U.S. Buyer Sear S specification does the commentary.
Note: JCSS Tatari ミ grades posted in Japan, Hikaru シ ェ – ズ industry mix specifications. 1 tensile strength: (K / cm) with 10 10 aspect sandals please note units. Each company different units, some with pounds / inch. Some men use with 1210 Kg / 5 cm, with state benefits Kg / 3 cm. Taiwan 1.0m / m * 36 “at the end of the cloth can be reached JCSS size 0.8m / m * 36 to pass comprehensive, zonal about 8-10 Kg / cm. Above the mean T / R / C lining Taiwan cotton fabric, yarn strength as well, fear not meet these requirements. 2. Elongation (%): vertical and horizontal with the men sandals with a 1O 10 15 25 Taiwan at the end of cloth are available through 3. tear strength : (Kg) aspect sandals with 33 men with 44 present the T / R / C cloth 1.0m / m can pass case, 0.8m / m sum to pass, Yi to about 2.5-3.5 Kg 4. rupture strength: (Kg/cm2) JCSS standard of 10 Kg/cm2, the T / R / C did not develop before the cloth can not be adopted and are currently the 1.Om / m × 36 “T / R / C fabric measured about 15 Kg/cm2, 0.8m / m * 36 “T / R / C of about 12 Kg a 13 Kg. 0.8m / m × 36″, T / R fabric measured in the 16Kg, 20 Kg / cm2 between. 5. Peel strength: (Kg / cm) and hair due to non-raising and other topics, all aspects of peel strength are different, generally along the longitudinal to try and reverse the hair to hair, but also test peel strength of the horizontal are as follows: reverse hair > horizontal> Shun Mao Yi state, the only smooth hair and reverse hair test, because the level of care are limited. JCSS requirements: sandals with l Kg / cm or more, men with 2 Kg / cm or more. Benefits the state holding strong 1.0m / m × 36 “control value of 6 Kg/3cm (good or poor hair to be super case this standard), the measured value of l0 Kg-20 Kg / 3 cm between 6 wear test: (Abrasion) Taber abrasion test to type and Wyzenbeek Abrasion widely accepted. wear test system is very important and effective method of identification of leather, fabric properties of good soil, good peel strength of the soil, a try at a glance, is very convenient. now the first volume of the aber most common type, according to Sears standards, have to use CS-17 轮, 1000 gm of the Load, 1000 Cycles and the surface layer without significant damage. JCSS equivalent of three qualified 7. frictions fall color (print fastness) test: Because the Medium is not enough ink or non-performing, or RP Ji-off migration, often less than the phenomenon of print fastness, test methods are many, JCSS line with the Jis-K6772 in white cotton cloth friction, while benefits with the state Department of Jis-L1079 method, Folding snd Abrasion, 3Kg of pressure rub 1000 back, the method is simple system / APE 7ES7.
8. resistance to rotation of the spin tests: mainly for White is concerned, according to J CSS standard, Department of exposure 50 hours (mean light tester, daylight exposure) did not significantly change color, usually non-yellowing PU Yu PU leather a lot of price difference, almost twice the domestic white PU failing to increase, so are the use of general PU, but added to prevent oxidation and UV absorption Ji Ji, Ting slow yellowing to the number of days.

advertising, advertising shoe Baike 8 anti-spin optical rotation tests: mainly for White is concerned, according to J CSS standard, Department of exposure 50 hours (mean light tester, daylight exposure) did not significantly change color, usually non-yellowing PU Yu PU leather a lot of price difference, almost twice the domestic white PU failing to increase, so are the use of general PU, but added to prevent oxidation and UV absorption Ji Ji, Ting slow yellowing to the number of days 9. resistance to flexion test: There are many ways to test resistance to buckling, the shoes with PU leather in Bally F1ex and SatraVamp Flex. off the federal system with Satra, the remaining countries to use Bally Flcx, this Bally is the world famous shoe BallY Shoe Factories Ltd.. are generally divided into two kinds of room temperature and cold tolerance: JCSS aspect of the 50,000 times at room temperature. A 10 ℃ aspect of the 20,000. Sears vertical temperature specification 200,000. cross 150,000 times a 10oF 7,000 times the integrated cross-Taiwan PU leather raw materials and technology of the plant different now buckling temperature resistant products about 30,000 a 100,000 dollars. a 10oC range of about 5,000-20,000 times, 10 sulfur-test: 20% (NH4) 2S Solution 15 minutes without abnormal 11. embossed stability : PU generally no questions its method of 250oF 10 minutes, and observe whether the disappearance of lines 12 hydrolysis resistance: past, we all thought that mixed plastic shoes will not lose a few times, it did not consider the hydrolysis of the subject, now plastic the more the more expensive Zhu, gradually will consider this topic. Sears requested that PU leather into 158oF and 100% relative humidity, temperature and humidity bath of seven days, and then compare their properties before testing public opinion and how it differs. Sears can not reduce the standard peel strength, resistance to buckling when the number can not be half of the low temperature case, but because the instrument limitations, the best slot relative humidity constant temperature and humidity can reach 98% ± 2%, it is generally accepted test method to 158oF (70oC) and 95% relative humidity . 13.Blocking Test (adhesion test): Sears specifications of 0.25 psi 30 min 180oF not mount with Japanese specifications similar to 3 Kg / 6 cm × 6 cm, 70. C, 120 min. 3 Kg / 6 Cm × 6 Cm = 0 .244 psi 1 80oF = 82oC five, is not no shoe trends: (a) the use of non-woven cloth to make a similar anger or wet skin. (b) development of dry PU foam PU, to imitate wet. because of the relationship between the current fluff , the lines are too thin to do good dry PU, PU foam can be done. (c) PU leather like leather handle inside, you can do inside cloth. (d) the use of T / R at the end of cloth instead of T / R / C enhance the physical properties of cloth. (e) hydrolysis of the improved antioxidant opinion, so two points in the current characteristics of the PU leather poor. (f) pollution-free water-based PU a solid color or 100-type points.

service hotline: 124-hour service Tel: ICP prepared Zhejiang No. 0 0 9. Resistance to flexion test: There are many ways to test resistance to buckling, the shoes with PU leather in Bally F1ex and SatraVamp Flex. Off the federal system with Satra, the remaining countries to use Bally Flcx, this Bally is the world famous shoe BallY Shoe Factories Ltd. . Resistance to cold temperature and generally divided into two kinds: JCSS room temperature aspect of the 50,000 times. One aspect of the 20,000 10 ℃. Sears 200,000 vertical temperature specifications. Cross 150,000 times. A comprehensive cross-10oF 7,000 times each. Taiwan PU leather raw materials and technology of the plant different. The resistance to buckling of the current product at room temperature ranging from about 30,000 a 100,000 times. Ranging from approximately 5,000-20,000 times a 10oC, 10 sulfur-test: 20% (NH4) 2S Solution 15 minutes without anything abnormal.
11. Embossed stability: general subject of PU no. The method of 250oF 10 minutes, and observe whether the disappearance of lines. 12 resistant to hydrolysis: In the past we all thought that mixed plastic shoes will not lose a few times, it did not consider the hydrolysis of the subject, the more plastic Zhu is now more expensive, will consider the subject gradually. Sears asked the PU leather into 158oF and 100% relative humidity constant temperature and humidity slot 7 days, and then compare the properties of the difference in public opinion before the trial. Sears can not reduce the standard peel strength, resistance to buckling when the number of room temperature is not lower case half. However, due to the limitation of the instrument, the best slot relative humidity constant temperature and humidity can reach 98% ± 2%, it is generally accepted test method to 158oF (70oC) and 95% relative humidity.
13. Blocking Test (adhesion test): Sears specifications of 0.25 psi 30 min 180oF not mount. With specifications similar to Japan 3 Kg / 6 cm × 6 cm, 70. C, 120 min. 3 Kg / 6 Cm × 6 Cm = 0.244 psi 1 80oF = 82oC
