Description
Technical field
The present invention relates to a kind of online test methods of circulating friction yam surface filoplume, belong to textile testing technology neck
Domain.
Background technique
Filoplume is to measure one of yarn and the important indicator of fabric quality, and Yarn filoplume, which refers to, is exposed at short fiber yarn table
The fiber head end or fibrous ring in face.When yarn stress, filoplume can not lack gripping stress point, thus Yarn filoplume is to yarn strength
Any help；And Yarn filoplume is excessive, and yarn friction increases, and yarn is easier to wear and rupture in following process, influences to add
Work efficiency rate；In weaving process, the easy tied up in knots of the excessive yarn of filoplume causes to be open unclear, influences weaving efficiency and quality.
Yarn filoplume is excessive, the weaving process degree of wear crosses big city and causes fabrics cloth cover filoplume excessive.Fabric surface filoplume is excessive, mistake
It is long, it easily tangles between filoplume in fibrous nodules, exterior quality decline, uneven dyeing degree is caused to improve, influence fabric vision, touching
The qualities such as feel.Therefore, not only Yarn filoplume needs to detect, but also corresponding yarn fabric filoplume should also become most basic survey
Try index.
Yarn filoplume test method mainly has visual observation method, weight method, photoelectric method at present, and wherein visual observation method is logical
Carry out naked-eye observation after crossing microscope amplification, weight method be by wipe out or burn off filoplume before and after weighing yarn obtain shared by filoplume
Weight ratio, both methods is accurately reliable, but time-consuming, low efficiency, is not suitable for the requirement that factory mass is quickly tested.Light
Electrical method test filoplume principle is to carry out fast measure Yarn filoplume by the way that optical signal caused by filoplume is converted into electric signal,
Main commercial test instrument has G566 filoplume tester, the Britain Shieley of Switzerland's Uster filoplume tester, Germany Zweigle
SDL098/98 filoplume tester, YG172A yarn filoplume tester of Chinese Chang Ling etc..U.S. Patent number 4948260, it is open
Nineteen ninety 14 days 08 month day, invention and created name are " Method and apparatus for examining hairiness
Of yarn ", this application discloses a kind of Uster filoplume tester using diffusing reflection method test yarn filoplume, testing principles
Are as follows: a branch of lasting monochromatic source (laser) is radiated on yarn body filoplume outstanding, and filoplume scatters out directional light；Yarn body sheet
Body is opaque in dead color, and the external filoplume of prominent yarn causes scattering light in light tone, detected by optical sensor；Surveyed filoplume H
Value is the ratio of filoplume total length and testing length, no unit.The specific test mode of G566 Yarn filoplume instrument be by 12 not
The photodiode of same distance arranged distribution detects corresponding different length filoplume radical；But G566 Yarn filoplume instrument is measured only
It is the filoplume number of one side of yarn, measured deviation is big, therefore in enterprise and is of little use.SDL098/98 filoplume tester uses
It projects counting method principle and carries out Yarn filoplume test, specific test mode is to detect optical detection device according to the filoplume of setting
For length adjustment on the corresponding position of yarn, detecting element is light-sensitive element, and yarn, by test point, is dashed forward with constant speed
Out yarn and be more than setting detection length the inswept light-sensitive element of filoplume, cause light flux variations, and be converted to electric signal, formed
Count pulse；All pulse summations that count are to set the hairiness index of filoplume length in the yarn fragment length of setting.It should
Test equipment principle is similar to the YG172A type Yarn filoplume instrument measuring mechanism of China, is all projection counting method principle；It is Chinese special
Benefit ZL201410576467.0, publication date on February 15th, 2017, patent name was a kind of " accurate test yarns of directional stretch formula
The method of line filoplume " provides a kind of method of accurate test yarn filoplume of directional stretch formula.Yarn filoplume instrument above-mentioned first is only
Yarn samples are disposably detected, one position of yarn is only surveyed once；Second, above-mentioned yarn filoplume tester device is directed to yarn
Line surface hairiness characteristic Design fails to combine Yarn filoplume test with thread friction performance.
The filoplume that Yarn filoplume carries after coming out one is yarn production, another is yarn by repeatedly friction regeneration
Filoplume, regeneration filoplume reach certain amount and length, will generate serious pilling phenomenon.At present to thread friction performance
Yam surface filoplume form feelings after the friction of Rubbing number needed for yarn and same number are mainly rubbed by yarn abrasion instrument
Condition characterizes, still cannot online in real time, continuously influence of the detection friction to yam surface performance.
