FYI Tester Instrument

Extrusion molding, also known as press molding, is a molding method that heats and melts the polymer solid material into a melt, and uses the extrusion effect of the screw to push the viscous fluid material through the die to form a continuous body with a cross-sectional shape similar to the die shape. The corresponding equipment is called a screw extruder. Screw extruder extrusion process Material (granules or powder) – added to the extruder – heated and transported forward – the material becomes a melt and is extruded – the melt enters the die head for molding – the molding sleeve is molded – cooled in the cooling tank – hauled – cut (or coiled) Classification of screw extruder According to the number of screws, it can be divided into single-screw extruder and multi-screw extruder; According to whether it can be vented, it can be divided into venting extruder and non-venting extruder; According to the presence or absence of screws, it can be divided into screw extruder and screwless

The impurity ratio is the percentage of impurities in the raw cotton sample to the sample mass. Impurity content is an important indicator for measuring cotton quality. Whether it is during mechanical or manual picking, these non-harmful impurity will inevitably be “mixed” the cotton. The percentage of impurity content directly affects the quality of cotton and the subsequent processing. For example, the impurity content of machine-picked cotton is generally between 8% and 16%. When the moisture content of seed cotton is greater than 9%, the adhesion between impurities and cotton fibers will increase with the increase of moisture, making it difficult to remove impurities, resulting in an increase in the impurity content of the ginned cotton. Therefore, controlling the impurity content in cotton is crucial to ensuring cotton quality. Working principle of trash analyzer YG041 Trash Analyzer mainly uses the difference in specific gravity between fibers and impurities to separate cotton fi

Cotton fiber is a textile raw material, and fiber strength is an important indicator. Since fiber materials are often processed into high-strength threads and ropes, the strength of fiber materials is an important determinant of their performance. The strength of fiber can directly affect the quality and performance of products such as fabrics and composite materials. Therefore, in the production of fiber products, it is very important to measure the fiber strength to ensure the quality and reliability of the product. Definition The force of a fiber is also called absolute force or breaking force. Breaking force is the force required when the fiber material is stretched to break by the outside world (the maximum external force that the fiber can withstand). The basic unit is Newton (N), and the derived units are centinewton (cN), millinewton (mN), kilonewton (kN), etc. The readings measured on various strength testers are all forces. For example, the breaking force of a single fiber an

Eight-Basket Oven is mainly suitable for measuring the moisture regain of raw materials and finished products such as cotton, wool, linen, silk, and textile printing and dyeing industries. It can also be used for other applications that require constant temperature drying. Eight-basket oven principle and working principle Carry out rapid drying according to the predetermined program and automatically weigh at certain time intervals. Then compare the two weighing results before and after. When the weight difference between the two adjacent times is less than the specified value, the test is considered completed and the results are automatically calculated. Eight-basket oven features Conforms to requirements of GB/T 5883, 9995, ISO 6348, 6741-1 and ASTM D1576, D2495, D2654 standards. Microcomputer temperature control, with PID self-tuning function, is reliable to control the oven’s temperature. Over-heat protection to ensure the operation safe. Once the oven is over-heated, cut off the h

  The ratio of the mass of non-volatile ester substances contained in fibers to the mass of the fiber is known as “Fiber Oil Content”. The oil content of fibers is usually used as one of the important indicators for fiber quality evaluation, which is of great significance for the processing and application of fibers. The oil content of fibers is closely related to their spinnability. Fibers with low oil content are prone to generate static electricity, while those with high oil content are prone to sticking and entanglement, which can affect the normal operation of textile production and processing. Under the condition of meeting the requirements of anti-static and smoothness, the lower oil content of chemical fiber is better. General Sampling Standards Scattered laboratory samples should be taken out as needed, and should not be less than 50g; The selection of the laboratory sample from short fiber batch samples shall be in accordance with GB/T14334, while the laboratory sample select
