Why:<\/strong> This test is used on garments to check the effects of sunlight, wear and tear and laundering.<\/p>\n What:<\/strong> This test determines the amount of pressure that is required to rupture a fabric. It is used on non-woven fabrics such as knits, lace and felt. The bursting strength is expressed in pounds.<\/p>\n Why:<\/strong>\u00a0Another method of testing fabric strength, particularly applicable for performance wear such as sportswear and uniforms.<\/p>\n What:<\/strong> Fabrics and clothing regularly come into contact with surfaces that can damage their appearance. Regular wear and washing can cause pilling<\/a> on the top layer (A pill, colloquially known as a bobble, fuzzball, or lint ball is a small ball of fibres that forms on a piece of cloth.\u00a0Pilling<\/b>\u00a0is a surface defect of\u00a0textiles<\/b>\u00a0caused by wear, and is considered unsightly to some.).\u00a0 <\/em><\/p>\n Evaluation should be made by considering the size, number and visibility of the piling as well as the type and degree of other surface change. After the tests, each specimen is evaluated on a 5-4-3-2-1 piling scale with the colour change and degree of fuzz on the surface appearance noted.<\/p>\n Why:<\/strong> Mostly performed on knitted textiles, these tests give ideas as to the end quality of the material and potential customer returns.<\/p>\n What:<\/strong> When materials rub against each other abrasion resistance occurs. Garments that are made from fibres that possess both high breaking strength and abrasion resistance, such as nylon, can be worn regularly before signs of physical wear appear.<\/p>\n Fabrics such as acetate, which is used extensively for lining garments, has poor abrasion resistance so doesn\u2019t last very long.<\/p>\n Why: <\/strong>Customer satisfaction and return rates related test.<\/p>\n What:<\/strong> This is used to determine the resistance to colour change, under various conditions, of dyed or printed fabrics. A cloth material that is brighter with deeper colours tends to be affected more than fabrics in lighter shades.<\/p>\n Certain elements determine whether textile colours will be affected. These include exposure to sunlight, pollution, perspiration, crocking, washing and dry cleaning.<\/p>\n Why:<\/strong>\u00a0Customer satisfaction and return rates related test.<\/p>\n The American Association<\/a> of textile chemists and colourists has a set of test methods and standards that are used in industry to test materials and garments.\u00a0These tests run into the hundreds and can be purchased through their website for \u00a330 to members and \u00a350 to non-members (prices are correct at time of publishing this article), per test and can then be carried out on your premises. The test methods are delivered via a link in your emailed receipt. The basic tests include the following:<\/p>\n This test method provides the general principles and procedures for determining the colourfastness to light of textile materials outdoors under glass. The test options described are applicable to textile materials of all kinds and for colourants, finishes and treatments applied to textile materials.<\/p>\n This test was originally developed in the 1930\u2019s and revised in 2016.<\/p>\n Crocking is the transfer of dye from the surface of a dyed or printed fabric onto another surface by rubbing.\u00a0 The more colour is transferred, the more the fabric “crocks”. Crocking determines the amount of colour transferred from the surface of coloured textile materials to other surfaces by rubbing.<\/p>\n Dye crocking is the result of colour loss by mechanical actions such as friction and abrasion.\u00a0 Crocking can be the result of a lack of penetration of the dyeing agent, the use of incorrect dyes or dyeing procedures, or the lack of proper washing procedures and finishing treatments after the dyeing process. If the textile dying or printing process is not done properly, the rubbing-off of dye from a fabric may occur.<\/p>\n Test procedures employing white test cloth squares, both dry and wet with water, are supplied. Considering that washing, dry cleaning, shrinkage, ironing, finishing, etc., may affect the degree of colour transfer from a material, the test may be made before, after, or before and after any such treatment. The testing method includes the rubbing of a coloured test specimen with a white crock test cloth under controlled conditions. Any colour that is transferred to the white test cloth is assessed by a comparison with the Gray Scale for Staining or the Chromatic Transference Scale<\/a> and a grade is assigned.<\/p>\n Leather goods testing is necessary to ensure that products made in this durable material are genuine, free of hazardous chemicals and can withstand everyday use. Testing methods and Leather Standards are similar to those set for the testing of textile garments.<\/p>\n The ASTM has formulated a set of standards for testing leather and leather goods. Each standard costs \u00a330 and can be downloaded from their website<\/a> The basic tests used for the fashion product testing of leather goods include the following:<\/p>\n What:<\/strong> The Baumann method was developed specially for testing leather garments. A defined shape is cut out of each leather specimen. Specialist jaws are fitted to a tensile testing machine which allows a load to be applied pulling across the cut-out in the leather sample. Two tears are generally produced- one from each end of the cut-out.<\/p>\n The Lastometer (Standard Test Method for Bursting Strength of Leather by the Ball Method ASTM D2207) test method was formulated to measure the bursting strength of leather shoe uppers by measuring the force required to introduce a spherical ended plunger through a piece of leather. The bursting load and extension will be proportional to the plunger diameter. The ball test method can be used to test a large variety of leathers and products and is applicable to light and medium weight leathers.<\/p>\n Why:<\/strong> These are”fit for purpose”\u00a0performance and safety-related tests. They also relate to customer satisfaction and return rates.<\/p>\n ASTM D5552<\/strong><\/p>\n What:<\/strong> Bleed resistance is an important characteristic in leather and this test is used to determine whether any colour bleeds will occur from the surface of the leather when it comes into contact with water. The test method is intended for use on finished articles such as shoes and handbags.<\/p>\n Why:<\/strong>\u00a0Customer satisfaction and return rates related test.<\/p>\n What:<\/strong> Fading is one of the main causes of damage to leather objects.<\/p>\n Aniline-coloured porous leathers tend to fade faster than more engineered pigmented leather. The light fastness of leather – as well as with textiles – is measured by means of the so-called blue scale test. Eight blue wool strips of descending light fastness are placed together with a sample of the leather to be tested in ultraviolet light. A part of the sample surface and a part of the wool strip surface is covered and compared after the exposure. The Xenon test simulates sunlight and is used to measure the fading sensitivity of leather.<\/p>\n Why:<\/strong>\u00a0Customer satisfaction and return rates related test. It is important to know how a material will perform before you invest in it being made into a final product. For example, for more expensive leather goods like handbags that will be exposed daily to sunlight, knowing that they will not discolour quickly and lead to customer dissatisfaction and high return rates is of utmost importance.<\/p>\n What:<\/strong> This test determines whether the colour will rub off the leather products onto other items under wet and dry conditions.<\/p>\n A white wool felt material would be loaded onto a machine and rubbed repeatedly over a stretched leather surface several times. The leather and felt are then tested for changes. The felt is tested for colour transference from the leather and the leather is tested for damage and fading.<\/p>\n Why:<\/strong>\u00a0Customer satisfaction and return rates related test. Especially with handbags worn under the arm or handheld and rubbing against clothes.<\/p>\n With all of the above tests, a minimum of three specimens should be tested for tolerance. All of the results should then be recorded and an average is taken from the three.<\/p>\n Testing centres operate worldwide, which makes sourcing them easy.<\/p>\n However, selecting the best one for your particular needs could prove a little trickier.<\/p>\n In the competitive field of fashion, it\u2019s important to stand out for the right reasons. Don\u2019t let a light shine on your company because of inferior products.<\/p>\n![\"\"](\"https:\/\/fashioninsiders.co\/wp-content\/uploads\/2017\/05\/idea-into-product-fashion-insiders.jpg\")
