Sei Kurema Kwejira Kuri Pasi Pezvinodiwa? Kugadzirisa Matambudziko Kubva Muzvikamu Zvisere

Kusakwana kweGSM yejira (magiramu pa square meter) kunogona kuita sedambudziko diki risina kana kukanganisa kutengeserana kwakajairika. Zvisinei, kune maodha ekutumira kunze kwenyika kana kutengeserana kwakanangana, GSM ndiyo inonyanya kukosha. Hazvishamisi kuti mabhizinesi awane odha yakakura ozongowana mari kana zvikumbiro nekuda kweGSM yejira isina kurongeka. Heano zvikonzero zvekusakwana kweGSM yejira.

1. Kuziva GSM Yejira

Kutanga, tarisa kana huwandu hweshinda uye huwandu hwejira huchienderana nezvinodiwa. Cheka muenzaniso we rectangular kana sikweya kubva pajira, uchiita shuwa kuti mipendero yawo yakabatana neshinda mbiri dze warp uye shinda mbiri dze weft. Yera kureba nehupamhi (mumasendimita) neruler yesimbi kuti uverenge nzvimbo yemuenzaniso wakachekwa (mumasendimita sikweya). Wobva wayera muenzaniso pachikero che balance (muma milligrams).
Fomura yekuverenga sampuro yeGSM:

GSM=1000Huremu (mg)​÷10000Nzvimbo (cm2)​=Nzvimbo (cm2)Huremu (mg)​×10

1.1 Nzira yeKuverenga Yakasanganiswa uye Chishandiso

Muenzaniso: Muenzaniso wejira une hurefu hwemasendimita manomwe (7 cm) uye upamhi hwemasendimita masere (8 cm), huremu hwemasendimita makumi manomwe nemakumi manomwe nemaviri (772 mg).

GSM=7×8772​×10=138 g/m2

1.2 Nzira yekushandisa zvishandiso chete

Shandisa muchina wekuenzanisa jira rakatenderera. Isa jira pasi wotenderedza muchina wekucheka uchitevedza wachi kakawanda kuti ucheke sampuli nhatu dzakatenderera (dzinotorwa dziri kure ne20 cm kubva pamucheto wejira). Yera sampuli uchishandisa electronic balance kuti uwane kukosha kweGSM chaiko.

2. Kuverenga GSM yeMachira Akapendwa

GSM inoreva huremu hwenzvimbo yejira, inowanzo ratidzwa mumagiramu pa square meter (g/m²) kana ma ounces pa square yard (oz/yd²). GSM chaiyo inokanganiswa zvakanyanya nehuwandu hwekusanganisa donje, huwandu hweshinda, upamhi hwejira rakapedzwa, uye maitiro ekupedzisira. Pazasi pane mafomura akareruka ekuverenga GSM:

2.1 Kuverengerwa kweGSM kweMachira Asina Kutambanudzwa Akadhayiwa

GSM=(Kuwanda kweWarp FabricGrey Warp Density​+Kuwanda kweWeft FabricGrey Fabric Weft Density​)×24.3
Muenzaniso: Verenga GSM yejira rine zvirevo 20×16 / 128×60 / 63″.

GSM=(20128​+1660​)×24.3≈246.6 g/m2

Huwandu hweGSM chaihwo hunosvika 242–248 g/m².

2.2 Kuverengerwa kweGSM kweMachira Akapedzwa Kutambanudza

GSM=Upamhi hwejira rakapedzwaUpamhi hwetsanga×(Kuverengwa kweWarp Yarn Density paLoom×22.17+Weft Yarn CountGrey Fabric Weft Density×21.4)
Muenzaniso: Verenga GSM yejira rine zvirevo C 78″ / 20×16+70D / 116×48.

GSM=5878​×(20116​×22.17+1648​×21.4)≈259 g/m2

Huwandu hweGSM chaihwo hunenge 260–265 g/m².

Cherechedza: 78″ zvinoreva upamhi hwetsanga, uye 58″ zvinoreva upamhi hwejira rapera.

3. Kuenzanisa Pakati Pekuverenga Kwakareruka Nekuyera Chaiko

Enzanisa kukosha kweGSM kwakaverengerwa uchishandisa fomura iri nyore neGSM chaiyo yakayerwa yemuenzaniso wejira rapera. Kazhinji, kutsauka mukati me ±5 g/m² kunoonekwa sekugamuchirika. Kutsauka kwakakosha kunoda ongororo yakakwana. Zvichibva pamakore eruzivo, mapatani anotevera akapfupikiswa:
Kutsauka mukati me ±5 g/m² kwakajairika mumamiriro ezvinhu akajairwa. Kana paine kusiyana kwakakura, teverai nhungamiro idzi: Yarn dzakagadzirwa neshinda dzine kutsauka kudiki.
  1. Kune yarns dzakasanganiswa dzepolyester-donje, polyester-nylon, uye yarns dzemakemikari fiber, conversion constant yakakwira kupfuura 583.1 constant inoshandiswa padonje rakachena. Yarns dzine nhamba imwecheteyo dzine nhamba yepamusoro ye tex count, zvichikonzera kuti GSM values ​​dzakaverengerwa dzive pasi pane chaiyo yaiyerwa.
  2. Shinda dzakamonerwa dzinoumbwa nekumonera shinda mbiri kana kupfuura pamwe chete. Nekuda kwekukombama kweshinda, huwandu chaihwo hweshinda hwakakora kupfuura huwandu hwezita, zvichiita kuti huwandu hweGSM hwakaverengerwa huve hwakaderera pane huwandu chaihwo hwakayerwa. Kutsauka uku kunonyanya kuoneka kana shinda dzese dziri mbiri dzakamonerwa nedzakamonerwa.
  3. Yarn dzakarukwa dzakavhurika dzinogadzirwa ne staple fibers uye dzinorasikirwa zvakanyanya panguva yekukwesha muchikamu chekutanga chekudhaya nekudhinda, zvichikonzera kuti GSM values ​​dzakaverengerwa dzive dzakakwirira kupfuura values ​​chaidzo dzakayerwa.
  4. GSM inowanzo wedzera ne5–6.5% mushure mekugezeswa.
  5. Pamachira akapendwa nerima, huremu hwedhayi hunoita kuti maGSM akaverengerwa ave akakwira zvishoma pane mareti chaiwo akayerwa.
  6. Pamachira akacheneswa kana kuti ane ruvara rwakajeka, kukosha kweGSM kwakaverengerwa kwakakwira zvishoma pane kukosha chaiko kwakayerwa.
  7. GSM inowedzera ne3–7% mushure mekurapwa kwependi.
  8. GSM inoderera ne3.5–6% mushure mekurapwa kwekusungwa.

4. Zvikonzero zveKuderedzwa kweMachira Akagadzirwa GSM

  1. Kutambanudza zvakanyanya panguva yekurapwa kunotungamira mukudzikira kwehuwandu hwematsipa.
  2. Kutambanudza jira rapera zvakanyanya kusvika paupamhi hwakakura zvakanyanya.
  3. Kuwanda kwealkali yakawanda uye kupisa kwakanyanya mushure mekugadzirwa zvinokuvadza shinda dzeshinda.
  4. Shinda mbishi yakatengwa yakatetepa kupfuura nhamba yakatarwa (semuenzaniso, shinda ye40S inoyera 41S).
  5. Kukwesha kwakanyanya kweshinda isina kuchekwa panguva yekuruka kunokonzera kudonha kwakanyanya kwefiber, zvichikonzera kuti shinda yakatetepa uye GSM iderere.
  6. Kudhaya zvakare kana kubvisa shinda panguva yekudhaya kunoita kuti shinda irasikirwe zvakanyanya uye shinda itete.
  7. Kupisa kwakanyanya kwemurazvo panguva yekupiswa kunoita kuti pamusoro pejira paome; maitiro ekubvisa saizi anozokanganisa shinda, zvichiita kuti itete.
  8. Kukuvadzwa pamusoro pejira panguva yekukwesha kana kusunda machira.
