Box type pilling tester to determine fiber pilling performance

As we all know, the intimate knitted underwear generally require wearing comfort, softness, breathability, warmth, elasticity and other functions. In order to achieve the above requirements, in recent years, knitted underwear in addition to the use of natural fibers cotton, but also a large number of cellulose fibers and cotton fibers have similar functions, now using more modal and man-made fibers.ifbTextile Testing Instruments, Testing Equipment Manufacturer

The box type pilling tester is used for pilling or hooking phenomenon caused by normal wear and tear, with unique controller, optional standard and other kinds of test speed for testing, and also with programmable 30rpm reversing system. Ltd. is a textile testing instrument manufacturer, can provide various textile testing instruments to meet the test requirements, the box type pilling tester is a special instrument to test the performance of fabric pilling, welcome customers with demand for timely telephone inquiries. In addition, the box type pilling tester in the textile pilling test test is very widely used, and for different standards have certain requirements.ifbTextile Testing Instruments, Testing Equipment Manufacturer

Three specimens of the same size are put into the box type pilling tester equipped with standard cork, and the specimens are tumbled in the cylinder with stirring bar and rubbed with other specimens or the cylinder wall to produce pilling. It is usually taken out after 30min free rotation at high speed, and the excess debris is vacuumed away and then compared with the standard sample under standard visual conditions to report the pilling and pilling of the fabric in terms of grade, 1 grade * poor, 5 grade *, with half grade allowed.ifbTextile Testing Instruments, Testing Equipment Manufacturer

With the refinement of the latter process for modal fiber knitted products, dyeing and shaping finishing. Modal knitted products have been accepted by the majority of consumers, it is more comfortable than cotton fiber knitted underwear wear, soft and breathable, and warm cotton fiber knitted products equivalent. Cotton knitted underwear will not produce pilling phenomenon, but it is not as comfortable to take and softness of modal knitted underwear, so in * knitted underwear widely used modal fiber. Modal fiber knitted products have the following characteristics: soft, smooth, silky feel, fabric comfortable to wear, has excellent breathability and moisture absorption, silk-like luster, bright color.ifbTextile Testing Instruments, Testing Equipment Manufacturer

The wet modulus of the fiber is high, the movement between the fibers in the hot water during dyeing and finishing increases, the friction coefficient increases, and the double friction between the machine and the blank increases the hairiness of the knitted fabric and thus makes it easy to produce the phenomenon of pilling, making the modal knitted underwear worse to wear. Therefore, modal fiber pilling needs to meet the strict standard requirements in order to be put into production life.
