Maitiro ekuitisa zvipfeko uye machira pilling bvunzo?

Munguva yekupfeka, zvipfeko zvinogara zvichiratidzwa kune friction uye zvimwe zvinhu zvekunze, zvichikonzera kuumbwa kwebvudzi pamusoro pemucheka, iyo inonzi fluffing. Kana fluff ikadarika 5 mm, vhudzi/mafiber aya anomonererana kuita mabhora asina kujairika, anonzi pilling.

01Sei iri piritsi?

bvudzi fibers

Sezvo jira rinoramba richikwizwa panguva yekushandiswa, mabhora efiber zvishoma nezvishoma anoswedera pedyo, uye mafiibhi akabatana nemucheka anoramba achikotama, kuneta, uye kunyange kuputsika nenzira dzakasiyana. Mabhora efiber anodonha kubva pamusoro pemucheka, asi iyo fiber hairiness payakaputsika inosara mushure meizvozvo. Panguva yekushandiswa ivo vanoramba vachiburitswa kunze uye kugadzira mabhora efiber zvakare.

Kazhinji, machira emvere dzemakwai uye machira emakemikari anowanzo piringirwa, kunyanya machira ane makadhi emvere dzemakwai kana machira ane makadhi akaita seshinda uye machira ecashmere. Kubva pakuona kweshinda uye chimiro chetishu, shinda inomonereka idiki, vhudzi rakakwirira, chimiro chejira chakasununguka, uye machira e twill uye satin ane mitsetse yakareba inoyangarara anowanzo piringirwa.

Pamusoro pezvo, kubva pamaonero ekugadzira fomu, kazhinji fibre twist yakakura, kubatana pakati pemafibhi kwakakura, uye chimiro chejira chakanyanya kusimba uye chakatsetseka, saka hazvisi nyore kupora. Pane zvinopesana, chiitiko chepiritsi chakanyanya kuoma mumicheka yakasanganiswa, kunyanya nylon, polyester, polypropylene, etc. Izvi zvinonyanya nokuti machira akasanganiswa ane zvakasiyana-siyana pakati pemafibhi, uye pamusoro pemucheka unotarisana nemucheka.

02Nzira yekuyedza mapiritsi?

Wakagadzirira kupfeka kuratidza

Kuti uve nechokwadi chekuchengetedza uye kunyaradza kuita kwembatya kana machira panguva yekushandiswa, machira anozoongororwa kuita kwepiritsi asati aitwa zvigadzirwa zvakapedzwa kana mushure mekunge zvipfeko zvapera.

The test method standardszvekutakura zvipfeko uye zvigadzirwa zvemachira ndezvi:
GB/T 4802.1-2008 "Circular trajectory method"
GB/T 4802.2-2008 "Modified Martindale Law"
GB/T 4802.3-2008 "Pilling Bhokisi Nzira"
GB/T 4802.4-2020 "Random Tumbling Method"

Kunyangwe ivo vese vachiyedza pilling degree yemachira, nzira dziri pamusoro dzinoshanda kune akasiyana machira ezvipfeko uye nheyo dzekushanda dzezviridzwa zvakare dzakasiyana. Kuitwa kwemapiritsi kwakaedzwa kunoratidzirwa mugiredhi, iro rinowanzokamurwa kuva giredhi 1 kusvika ku5. Kukura kwegiredhi, kashoma kuti zvipfeko zvive zvemapiritsi. Chiyero chese chinotara kuti index ≥ level 3 chigadzirwa chakakodzera.

2.1Circular trajectory method

Nheyo yeGB/T 4802.1-2008 "Circular Trajectory Method" ndeyokuti sampuli inokwizwa nebhurashi naironi uye jira rinoputika kana chete nejira rinoputika kwenhamba yakatarwa yenguva pasi pekumanikidzwa kwakatarwa kukonzera pilling pamusoro pemvura. muenzaniso.
Iyi nzira ine kukurumidza kuyedza kumhanya uye inogona kutevedzera kukweshera uye kupora kwejira mushure mekukochekera. Inokodzera zvipfeko zvakarukwa machira uye machira akarukwa senge sweatshirts uye T-shirts.
Kutora GB/T 4802.1-2008 "Circular Trajectory Method" yekuyedza kupfava kwemachira semuenzaniso, Mufananidzo 2 mufananidzo wekemikari staple fiber jira sampu ine pilling level 1 kusvika 5.

2.2Yakagadziridzwa Martindale nzira

Nheyo yeGB/T 4802.2-2008 "Modified Martindale Method" ndeyekuti pasi pekumanikidzwa kwakatsanangurwa, sampu yedenderedzwa inotenderera yakasununguka yakatenderedza yepakati axis perpendicular kune ndege yemuenzaniso, uye trajectory yemufananidzo weLissajous inoenderana nejira rimwe chete. kana Wool machira abrasives anoshandiswa friction, iyo yakakodzera yemubhedha mhando yekuedza.

2.3Pilling box nzira

Nheyo yeGB / T 4802.3-2008 "Pilling Box Method" ndeyokuti: sampuli inosungirirwa pa polyurethane tube uye yakashandurwa zvisina kufanira mubhokisi rehuni rakaputirwa nekork ine nguva dzose inotenderera. Mushure mehuwandu hwakatarwa hweflips, iyo fuzzing uye / kana pilling zvimiro zvinoonekwa zvinotsanangurwa uye kuongororwa. Inokodzera kuyedza machira ejuzi.

2.4Random tumbling nzira

Musimboti weGB/T 4802.4-2020 "Random Tumbling Method" ndeye kushandisa bhokisi rinodonha rinodonha kuita kuti jira ridonhe nekukwesha zvisina tsarukano mukamuri yekuyera yecylindrical yakarukwa necork lining uye yakazadzwa nediki grey pfupi donje. . Zvipfeko zvemukati zvechigadzirwa zviyero hazvisati zvataura nzira iyi.

Yekuyedza chenjedzo: Kana masamples asiri-hembe akatumirwa kunoongororwa, divi rekumberi kana rashandiswa rinofanirwa kucherechedzwa kudzivirira zvikanganiso zveparutivi. Pakukwirisa, makadhi, nezvimwe izvo zvine zvakasiyana parameter zvinodiwa, kutarisisa kunofanirwa kubhadharwa kune parameter kusarudzwa.
