Textile Testing Panorama Map Guide

What is textile testing?

textile testing

Textile testing, according to the relevant standards, using physical or chemical methods, testing the quality and performance of textiles for qualitative or quantitative, and making a test report. Textile testing serves the textile quality management system by analyzing and studying the composition, structure, and properties of textiles and their impact on quality from the point of view of their use and conditions of use, so as to determine whether the textile products meet the requirements of the specified standards and to determine the value of use.

★Technical guidelines

1 Testing personnel requirements

Personnel engaged in testing work need to be trained and assessed before starting work to obtain qualifications. Assessment evaluation should include theoretical knowledge and field operations. Staff engaged in the detection of large or complex instruments need the instrument operation assessment before starting work, and only after passing the assessment can independently engage in testing activities. For example, the length of cotton hand pulling, chemical fiber linear density determination, chemical fiber length assessment, and other testing work, testing personnel need to have a certain amount of time of practical experience before they can independently carry out testing work.

The laboratory should regularly evaluate the continued competence of the testing personnel and maintain files on the qualifications, training, skills, and experience of the testing personnel. The laboratory’s training program should include the relevant technical requirements for training, the equipment used, and training objectives, as well as the special requirements of each test.

4 Testing environment: how the laboratory meets the requirements of the Code

Safety Design The laboratory should establish and implement procedures regarding laboratory safety and personnel health protection with safety and protective equipment and facilities, including but not limited to personal protective equipment, smoke alarms, emergency sprinklers, and eyewash devices, fire extinguishers, first aid kits, ventilation facilities, etc.
Test instrument requirements Select testing instruments that meet testing standards and are certified by quality systems (such as ISO 9001),which are in terms of accuracy, range, and stability, such as TESTEX textile testing instruments.
Specific Environmental Requirements The standard stipulates that the test items with environmental requirements must meet the relevant requirements of temperature and humidity, standard illumination, odor assessment of environmental conditions.  Cotton color grade inspection, color fastness rating, pilling rating, appearance rating inspection, yarn blackboard strip rating test environment must use a dedicated space to ensure that the rating results are not affected by other light sources in the adjacent area, the test environment to meet the standard illumination, the relevant requirements of the test room wall color.
Environmental requirements Environmental protection laboratory has been the goal of international professional laboratory construction, laboratory wastewater, the waste gas composition is complex, containing acidic, alkaline, organic class, inorganic class, biological class, and other components, the random discharge of these wastes, the corresponding processing media put forward high requirements.
Management System Laboratory management needs to realize the monitoring of the operation status of experimental instruments, room temperature, humidity, pressure, cleanliness, air disturbance, vibration disturbance, and other monitoring, as well as gas leakage, low pressure monitoring, and linked fire, security monitoring, etc. Laboratory operation involves many aspects such as reagents, consumables, documents, samples, data, instruments, personnel, etc. For laboratories with large experimental tasks or requiring fine management, how to achieve efficient, economical, and orderly experimental work needs to be studied in depth.

★Systematic guidelines

Quality management is a system, to ensure the quality of textile products, only testing is not enough, the relevant personnel, processes, etc. must also meet the relevant processes of Conformity Assessment: testing, inspection, certification, accreditation. In the following, I will analyze the four aspects, specifically the system related to the conformity assessment of textiles.

1 Conformity Assessment: testing, inspection, certification, accreditation.

According to ISO/IEC 17000, conformity assessment refers to the confirmation that the requirements related to products (including services), processes, systems, people, or institutions are met. It includes four parts: testing, inspection, certification, and accreditation.

Testing According to technical standards, use the instruments and equipment to test a given object and provide test data. Testing work is an independent technical activity that can provide services for inspection and certification but is not equivalent to inspection.
Inspection Relying on experience and knowledge, based on test data and other information, who review the conformity of product design, product quality, production processes, etc., to see if they comply with the relevant regulations.
Certification By having a third-party nature of the body to prove that the product, service, process, or personnel in line with the relevant standards and norms assessment behavior, including product certification and system certification, etc.
Accreditation Accreditation bodies to the technical competence of the certification bodies, inspection bodies, laboratory to give proof of conformity assessment activities.

According to the nature of the activities of conformity assessment, it can be divided into three categories: first-party, second-party and third-party.

First-party It refers to the assessment implemented by manufacturers, service providers and other suppliers, such as self-inspection and internal audit carried out by manufacturers to meet their own R&D, design and production needs.
Second-party It refers to the assessment carried out by the demand side such as users, consumers or buyers, such as the inspection of goods by buyers and factory inspection before signing contracts.
Third-party It refers to the assessment implemented by third-party organizations independent of both supply and demand, such as product certification, management system certification, various types of accreditation activities. Certification, accreditation and inspection and testing activities issued to the community with the role of proof are third-party conformity assessment.

Compared with the first-party and second-party conformity assessment, the third-party conformity assessment is carried out by institutions with independent status and professional competence strictly in accordance with national or international standards and technical specifications, which has higher authority and credibility, and thus is generally recognized by all parties in the market, which can not only effectively ensure quality and protect the interests of all parties, but also enhance market trust and promote trade facilitation.

2 Common inspection and certification institutions

There are many international textile inspection and certification bodies, responsible for the inspection and certification of international trade goods, the common well-known institutions are listed below.

SGS SOCIETE GENERALE DESURVEILLANCE S.A. is currently the world’s largest group of companies specializing in international commodity inspection, testing and certification, and is a comprehensive inspection and certification body.
ITS ITS is an international commodity inspection organization that buys powerful inspection agencies in the world to form its own inspection group. the ITS group includes the Carpenter Group, Intertek International, Anna Laboratories, Ingenious Lloyd’s Agency, Intertec Services, etc.
UL UNDERWRITERS LABORATORIES INC. is the most authoritative in the United States, but also the largest inspection body in the world, which testing and identification of private inspection agencies. The laws of many U.S. states explicitly provide that home appliances without the UL mark are not allowed to be sold in the market.
BSI The British Standards Institute, a provider of international standards services that integrates five complementary businesses: standards research and development, standards technical information provision, product testing, system certification and commercial inspection services, provides services worldwide.
TUV Rheinland, Germany
STR Specialized Technology Resources, France
CQC China Quality Certification Center

The results of the conformity assessment are usually publicized to the society in written form such as certificates, reports and logos. Through this public proof, the problem of information asymmetry is solved in order to obtain the general trust of relevant parties and the public. The main forms are.
— certification certificate, logo.
–Accreditation certificate, logo.
–Certificate of inspection, test reports.

SGS certification

3 The significance of conformity assessment

3.1 For consumers, consumers can benefit from conformity assessment, because conformity assessment provides the basis for consumers to choose products or services.

3.2 For textile enterprises, there are many orders and self-developed products, so there need so many times of testing and inspection. If every test is sent to a third-party institution testing and inspection, in terms of time and money will cause a huge waste. Therefore, the establishment of their own testing laboratories, set inspection regulations will be a long-term solution.

3.3 For the regulatory authorities, all kinds of inspection and testing, certification activities of the assessment body is very much, the good and the bad, so that users have no choice, and even damage the interests of the parties concerned. To ensure the authority and impartiality of inspection and testing results, accreditation activities came into being, providing the means to implement laws and regulations and achieve public policy goals.

3.4 For international trade, with the development of economic globalization, accreditation activities in various regions require the adoption of uniform standards and rules procedures, and then developed into a regional certification system. For example, the International Organization for Standardization (ISO) promotes the establishment of the ISO 9001 international quality management system, and the certification activities based on this standard.
