Yarn friction tester is the quality and performance of knitted fabrics depend on the characteristics of the knitted raw materials, the structure and specifications of the knitted fabrics, dyeing and finishing, and other factors. Among these, the performance of the knitted raw materials is the primary factor influencing the characteristics of knitted fabrics. Different types of knitted fabrics require different raw materials. Currently, most knitted fabrics used for underwear are made from cotton yarn; the raw materials for sock products include cotton yarn, wool, and chemical fibers. Wool sweaters are primarily made from wool, acrylic, acrylic blended yarn, etc. The main raw materials for knitted jackets are polyester, nylon, acrylic, blended yarn, and new textile materials (such as staple fibers, differentiated fibers, etc.); raw materials for special industries are primarily glass fiber, metal wires, and aromatic fibers. Raw material components can be pure yarn, which contains only one type of fiber, or blended yarn, which contains two or more types of fibers; (e.g., colored yarn, slub yarn, knotted yarn, core-spun yarn, etc.). Additionally, the emergence of new raw materials, such as special-shaped chemical fibers, composite fibers, and especially ultra-fine denier fibers, has opened up new methods for knitted yarn production.

During the process of forming knitted fabrics on a knitting machine, yarn is subjected to complex mechanical actions such as stretching, bending, twisting, and friction. To ensure normal production and product quality, knitting yarn must meet various requirements:

1. Yarn should have sufficient strength and extensibility

2. Yarn should have good softness

3. Yarn should have a certain degree of twist

4. The linear density of yarn should be uniform, and yarn defects should be minimal

5. The yarn should have good moisture absorption properties

6. The yarn should have a good finish and low friction coefficient

Knitting yarn should be free of impurities and oil stains and should be very smooth. Rough yarn can cause severe wear on parts, which are easily damaged. There are many flying sparks in the workshop, which not only affect workers' health but also impact the productivity of the knitting machine and the quality of the fabric.

Additionally, during the weaving process, yarn comes into friction contact with various mechanical components to impart a certain degree of resistance, thereby generating yarn tension. Therefore, when passing through ring machines, yarn with rough surfaces or coarse yarn will produce higher yarn tension, which will affect the uniformity of yarn tension and result in uneven loop structure. To reduce the yarn's friction coefficient, the yarn surface can be treated with anti-adhesive agents, lubricants, or wax.

When friction occurs as the yarn slides over other surfaces, tension is generated due to friction. In practical applications, the yarn passes through several sinkers and hooks. As the friction coefficient increases, yarn tension increases significantly. The increase in tension depends not only on the friction coefficient but also on the yarn guidance and the total wrapping angle when the yarn slides.

During textile processing, relative movement typically occurs between yarns, as well as between yarns and machine components, resulting in friction between yarns or between yarns and other materials. Sufficient friction between yarns is a necessary condition for good dimensional stability of the fabric; however, excessive friction can cause pounding during weaving and adversely affect fabric quality. The magnitude of the friction coefficient also directly influences the appearance and style of the fabric. For example, friction between yarns to some extent determines the fabric's interlacing resistance. If the interlacing resistance is too high, the fabric typically feels hard and rough, and distortion is likely to occur. Additionally, the friction force between yarns plays a decisive role in the fabric's shear deformation resistance, and the circular shape of the chest and back areas requires the fabric to have good shear deformation capability. Therefore, determining the yarn friction coefficient is of significant importance.

UTSTESTER's Y019A/B Yarn Friction Tester (ASTM D 3108) is used to measure the friction characteristics of yarns. This tester is suitable for determining the dynamic friction coefficient of chemical fiber filaments and other material yarns, and can also be used for textiles such as top rolls. The friction coefficient measurement of the device is an indispensable testing tool for evaluating the friction coefficient of filaments and textile equipment.

Salt is one of the most common compounds in the world and can be found in oceans, the atmosphere, on land surfaces, in lakes, and in rivers. When salt enters tiny droplets in the atmosphere, it forms a salt fog environment whose main component is sodium chloride.

1. What is salt spray testing?

Salt spray testing is used to evaluate the resistance of products or metal materials to salt spray corrosion. The results of salt spray testing are used to determine product quality, and whether the results are correct and reasonable is key to accurately measuring the resistance of products or metals to salt spray corrosion.

2. Classification of Salt Spray Test Methods Artificial simulated salt spray tests include three different test methods with varying requirements.  

(1) Neutral Salt Spray Test (NSS Test) is the earliest developed and currently most widely applied accelerated corrosion test method. It uses a 5% sodium chloride saltwater solution with a pH value adjusted to the neutral range (6.5–7.2) as the spray solution. The test temperature is set at 35°C, with a required salt fog deposition rate of 1–2 ml/80 cm/h.  

Application scope: metals and alloys, metal coatings, conversion coatings, anodized coatings, and organic coatings on metal substrates.

(2) The Acetic Acid Salt Spray Test (ASS Test) was developed based on the neutral salt spray test. It involves adding some glacial acetic acid to a 5% sodium chloride solution, lowering the solution's pH to around 3, making the solution acidic, and resulting in acidic salt spray instead of neutral salt spray. Its corrosion rate is approximately three times faster than that of the NSS test.

Application scope: decorative coatings of copper + nickel + chromium or nickel + chromium, anodized films on aluminum, and organic coatings.

(3) The Copper-Accelerated Acetic Acid Salt Spray Test (CASS Test) is a newly developed rapid salt spray corrosion test abroad. The test temperature is 50°C, and a small amount of copper salt (copper chloride) is added to the salt solution to strongly induce corrosion. Its corrosion rate is approximately 8 times that of the NSS test.

Application scope: decorative coatings of copper + nickel + chromium or nickel + chromium, anodized aluminum films, and organic coatings.

3. How long is the conversion time between salt spray testing and natural environment exposure?

Based on existing industry standards (theoretical values), the conversion relationship between 24-hour salt spray testing and natural environment exposure is as follows:

Neutral salt spray testing for 24 hours ⇌ 1 year of natural environment exposure

Acetic acid salt spray testing for 24 hours ⇌ 3 years of natural environment exposure

Copper salt accelerated acetic acid salt spray testing for 24 hours ⇌ 8 years of natural environment exposure

There is no uniform standard for salt spray test duration, which should be flexibly selected based on product type, industry standards, and testing objectives. It is primarily divided into three categories:  

(1) Short-term testing (24–72 hours)  

Purpose: Rapid screening of the basic corrosion resistance of materials or coatings, such as small appliance housings, connectors, etc.  

Example: Exposed automotive hardware: 24-hour neutral salt spray test (NSS); Electronic component factory testing: 24–48 hours.

(2) Medium-term testing (72–168 hours)

Purpose: To assess durability in moderate corrosion environments, such as automotive components and outdoor building materials.

Example: Hardware fittings (doors, windows, railings): 96–168 hours; photovoltaic mounting brackets: 72–240 hours.

(3) Long-term testing (over 168 hours)

Purpose: Reliability verification in extreme environments (e.g., marine engineering, aerospace), with durations up to 1,000–2,000 hours.  

Examples: Ship components: starting at 500 hours, some exceeding 2,000 hours; aerospace fasteners: 480–1,000 hours of neutral or alternating salt spray testing.

Salt spray test duration is a dynamic parameter that requires flexible design based on product application, environment, and standards. Short-term tests (24 hours) are suitable for production line spot checks, while thousand-hour-level tests serve as the “quality gatekeepers” for marine and aerospace equipment. Reasonable time planning can avoid the cost waste of excessive testing while accurately exposing corrosion protection shortcomings.
