1. Yog vim li caslinenxav txias?
Linen yog tus cwj pwm los ntawm qhov txias txias, tuaj yeem txo qhov tawm hws, hnub kub hnav cov paj rwb ntshiab, tawm hws yog 1.5 npaug ntawm linen. Yog tias koj muaj ntaub pua chaw nyob ib puag ncig koj thiab qhwv nws hauv koj lub xib teg, koj yuav pom tias cov ntaub pua chaw hauv koj txhais tes yeej txias thiab tsis kub. Sim ib lub paj rwb. Nws yuav kub tom qab ib pliag.
LinenNws yog qhov txias rau hnav thaum lub caij ntuj sov vim nws yog hygroscopic thiab hygroscopic natural fiber ntau.
Flax yog ib hom tshuaj ntsuab, flax ntau li ntau pua hom, kev lag luam textile yog siv fiber ntau flax, kev loj hlob ntawm subcold huab cua, tus pas nrig txoj kab uas hla yog nyias cog ntom, qhov siab feem ntau yog nruab nrab ntawm 1 ~ 1.2 meters, lub pas nrig txoj kab uas hla yog feem ntau ntawm 1 ~ 2cm.
Flax nyob rau hauv lub voj voog loj hlob 30-40 hnub, txhua 1kg ntawm flax loj hlob, muab 470kg dej, yog li flax ib txwm muaj zog nqus dej thiab muaj peev xwm thauj dej.
Nyob rau hauv lub tshuab electron microscope, flax fiber zoo li hollow xyoob, lub hollow qauv ntawm flax fiber, muaj ib tug loj cheeb tsam, yog li ntawd flax fiber muaj zog hygroscopic thiab hygroscopic zog. Flax tuaj yeem nqus tau li 20 npaug ntawm nws tus kheej qhov hnyav ntawm dej, flax tuaj yeem nqus tau 20% ntawm nws tus kheej qhov hnyav ntawm dej, thiab tseem tswj tau qhov kev xav qhuav.
Nws yog vim muaj zog hygroscopic thiab hygroscopic zog ntawm linen uas hnav linen khaub ncaws los yog pw linen nplooj nyob rau hauv lub caij ntuj sov tsim capillary tshwm sim thaum nyob rau hauv kev sib cuag nrog daim tawv nqaij, thiab tib neeg hws thiab dej vapor yog sai absorbed thiab ua los ntawm linen fibers, ua rau tib neeg. lub cev xav tias qhov kub thiab txias poob thiab daim tawv nqaij qhuav. Yog li ntawd, flax xav tias txias.
2.Vim li cas linen tsis muaj hluav taws xob zoo li qub?
Flax, hemp, flax thiab lwm yam hemp fibers yuav luag tsis muaj hluav taws xob zoo li qub. Cov dej noo ntau dua ntawm flax (uas tuaj yeem nkag siab yooj yim raws li cov ntsiab lus dej hauv flax fibers) yog 12%, uas yog qhov siab ntawm cov nroj tsuag fibers. Ua ke nrog lub hollow qauv ntawm flax, nws muaj zog hygroscopic khoom, yog li qhov zoo thiab tsis zoo nqi tshuav ntawm flax fiber tsis tsim hluav taws xob zoo li qub.

Yog li ntawd, ntxiv rau cov khaub ncaws, linen yog ib qho zoo heev hauv tsev textile fabrics, txawm tias xws li ntaub pua chaw pw, curtains, los yog sofa npog, tuaj yeem ua kom huv si ntev dua thiab txo qhov zaus ntawm kev tu. Nyob rau hauv cov ntaub ntawv zoo tib yam, lub ntsiab xav tau los sib xyaw 10% linen, uas tuaj yeem cuam tshuam hluav taws xob zoo li qub.
3.Vim li cas linen zoo rau kev tiv thaiv UV?
(1) Flax fiber, muaj UV-absorbing hemicellulose.
(2) Qhov saum npoo ntawm flax fiber muaj lub ntuj ci thiab tuaj yeem cuam tshuam qee lub teeb.
Kev lag luam textile xav tau cellulose hauv cov nroj tsuag fibers. Flax yog txawv los ntawm paj rwb, uas yog ib tug txiv hmab txiv ntoo thiab nws lub ntsiab tivthaiv yog cellulose, muaj ob peb impurities.
Flax fiber, ntawm qhov tod tes, yog bast fiber ntau los ntawm cov qia. Los ntawm kev ua haujlwm, flax fiber ntau tuaj yeem tau txais yog ib feem me me. Ib hectare (100 acres) ntawm thaj av tuaj yeem tsim tau 6,000 kilograms ntawm flax raw khoom, tom qab ntaus hemp - zuag, tuaj yeem tsim tau 500 kilograms rau hauv luv luv flax, 300 kilograms rau hauv luv luv flax, flax ntev fiber ntau 600 kilograms.
Hauv flax fiber, cov ntsiab lus cellulose tsuas yog 70 mus rau 80%, thiab cov pos hniav ntxiv (linolenin symbiosis) cov ntsiab lus yog:
(1) Hemicellulose: 8% ~ 11%
(2) Lignin: 0.8% ~ 7%
(3) Lipid ciab: 2% ~ 4%
(4) Pectin: 0.4% ~ 4.5% muaj pes tsawg leeg
(5) Nitrogenous tshuaj: 0.4% ~ 0.7%
