(5), fformiwla trosi tex (tex) a chyfrif modfedd (S): gwerth tex=K / SK: edafedd cotwm pur K=583.1 ffibr wedi'i buro K=59 0. 5 edafedd cotwm polyester K=587.6 edafedd viscose cotwm (75: 25) K=edafedd cotwm dimensiwn 584.8 (5 0: 5 0) K=587. 0
(6), tex (tex) and metric number (N) conversion formula: tex=1000 / N
(7), the conversion formula of dtex (dtex) and denier (D): dtex=10D / 9
(8), fformiwla trosi cyfrifx a chyfrif modfedd (S): dtex=1 0 Gwerth K / SK: edafedd cotwm pur K=583.1 ffibr wedi'i buro K=59 0 5 edafedd cotwm polyester K=587.6 edafedd viscose cotwm (75: 25) K=584.8 edafedd cotwm (5 0: 5 0) K=587. 0
(9), conversion formula of dtex (dtex) and metric count (N): dtex=10000 / N
(10), the conversion formula of metric centimeters (cm) and inch inches (inch): 1inch=2.54cm
(11), fformiwla trosi reis metrig (M) ac iard Saesneg (yd): 1 iard= 0. 9144 metr
(12), the conversion formula of satin square meter weight (g / m2) and mm (m / m): 1m / m=4.3056g / m2
(13), fformiwla trosi pwysau gwirioneddol sidan a phwysau punt: pwysau punt (lb)=pwysau sidan y metr (g / m) * 0. 9144 (m / yd) * 50 (yd) / 453.6 (g / yd)
1. Feel visual method: This method is suitable for textile raw materials in loose fiber state.
(1), cotton fiber is shorter and thinner than ramie fiber and other hemp craft fiber and wool fiber, often with various impurities and defects.
(2), hemp fiber feels rough and hard.
(3), the wool fiber is curled and full of elasticity.
(4). Silk is long filament, long and slender, with special luster.
(5) Among chemical fibers, only the viscose fiber has a large difference in dry and wet strength.
(6), spandex yarn has a very large elasticity, its length can be stretched to more than five times at room temperature.
2. Dull arsylwi microsgopig: Mae i adnabod y ffibr yn ôl nodweddion morffolegol adrannol hydredol a chroes - y ffibr.
(1), ffibr cotwm: croes - siâp adrannol: gwasg gron, gyda gwasg ganol; siâp hydredol: rhuban gwastad, gyda thro naturiol.
(2), ffibr cywarch (ramie, llin, jiwt): morffoleg adrannol croes -: gwasg - crwn neu amlochrog, gyda cheudod; morffoleg hydredol: gyda chymalau llorweddol, streipiau fertigol.
(3), ffibr gwlân: morffoleg adrannol croes -: crwn neu bron yn grwn, rhai â pith; morffoleg hydredol: graddfeydd ar yr wyneb.
(4), ffibr gwallt cwningen: morffoleg adrannol croes -: siâp dumbbell -, gyda mwydion gwallt; morffoleg hydredol: wyneb cennog.
(5). Ffibr sidan Mulberry: morffoleg adrannol croes -: triongl afreolaidd; morffoleg fertigol: llyfn a syth, gyda streipiau i'r cyfeiriad hydredol.
(6), viscose cyffredin: croes - siâp adrannol: igam-ogam, gwain - strwythur craidd; siâp hydredol: rhigolau hydredol.
(7). Ffibr cryfder cyfoethog -: morffoleg adrannol croes -: llai o siâp dannedd, neu'n grwn, hirgrwn; morffoleg hydredol: arwyneb llyfn.
(8), ffibr asetad: morffoleg adrannol croes -: trilobal neu igam-ogam afreolaidd; morffoleg hydredol: streipiau hydredol ar yr wyneb.
(9), ffibr acrylig: siâp - siâp adrannol: siâp crwn, dumbbell - neu siâp deilen -; siâp hydredol: wyneb llyfn neu streipiog.
(10), Ffibr clorin: siâp adrannol croes -: bron yn gylchol; siâp fertigol: wyneb llyfn
(11), ffibr spandex: morffoleg adrannol croes -: siâp afreolaidd, crwn, tatws - siâp; morffoleg hydredol: wyneb tywyll a dwfn, gyda streipiau siâp esgyrn - aneglur.
(12), polyester, neilon, ffibr polypropylen: siâp adrannol croes -: crwn neu siâp; siâp hydredol: llyfn.
(13), ffibr finylon: croes - siâp adrannol: gwasg - crwn, lledr - strwythur craidd; siâp hydredol: rhigolau 1 i 2.
