Rau cov neeg feem coob, cov txiv neej nyiam yog cov ntaub uas pheej yig lossis cov khoom siv ntxiv rau cov ntaub ntawv ntuj. Nyob rau tib lub sijhawm, lub npe scientific ntawm cov khoom siv hluav taws xob polyester cov suab zoo li Polyethylene Terephthalate. Qhov fiber ntau thiab cov ntawv luam tawm ntawm nws hauv ntau lub teb chaws yog tsim nyob rau hauv ntau lub npe (Dacron, Terleran, thiab lwm yam). Nws tus tsiaj ntawv luv tus tsiaj lossis tsiaj tuaj yeem pom ntawm cov hwj yas, ntau lwm cov khoom siv tshuaj kho thiab cov tshuaj Lavsana.
Tau txais thiab cov khoom ntawm Lavsana
Txoj kev tshawb fawb thiab kev txhim kho ntawm cov polyesters pib nyob rau hauv lub xyoo peb caug ntawm xyoo 1946, tab sis tau luam tawm hauv xyoo 1941, tab sis tau tshaj tawm hauv xyoo 1941, tab sis tau tshaj tawm hauv xyoo 1941, tab sis tau tshaj tawm hauv Asmeskas tau hu ua cov ntawv sau luv ntawm chav kuaj cov molecular sib txuas ntawm USSR Academent. Tau txais nyob rau hauv cov synthetics (nyeem txog synthetic cov tawv nqaij ntawm no: http://tkaninfo.ru/tkani/ Sinteticheskie.html). Nws cov cuab yeej muaj txiaj ntsig zoo heev. Cov no suav nrog:
- Lub zog siab thiab coj kev tiv thaiv;
- elasticity;
- Neutrality thiab kuj mus rau qhov kev txiav txim ntawm tshuaj lom neeg cov tshuaj lom neeg;
- Zoo sib raug zoo hauv kev muaj kev txheeb ze rau biologes ntswg;
- Kuj muaj cov acids thiab qaug zog alkaline;
- Zoo nkauj melting taw tes (260 degrees).
Raws li rau cov ntaub, Lavsan yog tus cwj pwm los ntawm:
- Tsawg fermentation;
- zoo-tiv thaiv kev tiv thaiv zoo;
- Yooj yim ntawm kev saib xyuas;
- Tsis muaj shrinkage thiab deformation.
Nyob rau tib lub sijhawm, cov khoom siv no muaj qee qhov khoom tsis zoo, suav nrog:
- phem tsis zoo noo noo;
- ua rau nws nyuaj rau kev ncig cua ntawm lub cev saum npoo;
- crept thaum ciav;
- dhuav tsis zoo;
- hluav taws xob;
- Tej zaum yuav ua kom tawv nqaij rhiab.
Lovesan siv rau dab tsi?
Nws yuav zoo li tsis npaj txhij txog, tab sis lub qhov tseem ceeb ntawm kev siv Lavsana hauv peb lub tebchaws yog qhov tsim cov hnab yas.
Ib qho ntxiv, nws yog dav siv rau kev txhawb nqa lub log tsheb tsheb, ua cov tapes ntawm tapes rau conveyors, ruaj hoses ntawm ntau lub hom phiaj. Cov khoom tshwj xeeb ntawm Polyethylene terephallate LED nws qhov dav siv siv hauv cov khoom siv thiab cov cuab yeej ua. Nws ua ib zaj duab xis rau kev thaij duab, zaj yeeb yaj kiab thiab duab xoo hluav taws xob rau kev siv suab thiab cov duab sib nqus no tau txo qis), nrog rau lub computer floppy disks.

Lub insulating cov khoom ntawm cov tshuaj no, lub zog thiab cov yas ua rau nws siv ua insulating thiab fastening cov khoom siv hluav taws xob thiab hluav taws xob. Nruab nrab lavasan fiber ntau - cov khoom phais feem ntau uas tsis tso cai rau deform thiab lawb tawm postoperative seamoditive, tsis ua rau cov roj postive, tsis ua rau cov pa thiab kev sib tw.
Ntev thiab txhim khu kev qha lavsana cov ntawv tau zoo los ntawm ultraviolet hluav taws xob thiab yog siv hauv kev ua liaj ua teb thiab kev tsim kho. Cov tshuaj no yog lub hauv paus ntawm ib qho kev paub zoo metallized much, uas muaj siab thermal insulating thiab reflective cov khoom, thiab kuj zoo nkauj heev. Thiab, ntawm chav kawm, cov khoom siv hluavtaws hluavtaws feem ntau yog siv hauv kev lag luam textile, rau kev tsim khoom:
- Cov ntaub ntawv hauv tsev, feem ntau cov ntaub thaiv hluav taws xob;
- Ua haujlwm thiab cov ris tsho tshwj xeeb;
- Xws li cov khaub ncaws rau cov txiv neej, poj niam thiab cov menyuam yaus (ris tsho, ris, tiab, hnav khaub ncaws, tsho);
- ntaub pua txaj txaj;
- Sov thiab ua kom zoo rau hauv knitwear rau ntau lub hom phiaj.
Tus hlub ntshiab yog ruaj khov, ruaj, yooj yim mus saib xyuas, tab sis theej tawv thiab tsis yooj yim thiab sab nraud zoo li flax Cov. Nws yog siv raws li kev sib tw, nrog rau tsev neeg textiles, ua ntej ntawm txhua yam, kab hlau. Cov ntaub thaiv zoo li no tsis ntshai hmoov av thiab tsis txhob hlawv, lawv muaj kev tu thiab yooj yim rau kev ua lag luam lossis Dacha sab hauv.
Tag nrho polyethylene terephthalate fiber ntau yog siv los ua ntxiv rau cov khoom ntxiv rau cov khoom siv thiab cov khoom siv khoom siv, uas txo qis thiab hnav tsis kam.
- Xws li cov ntaub npuag zoo li cov ntaub plaub nrog cov Lavsan, siv lub koob hmoov zoo rau yuav luag ib nrab xyoo: nws yuav luag tsis muaj kev pom thiab khaws ib qho kev nyiam lub ntsej muag rau lub sijhawm ntev heev.
- Raws li rau cov ntaub ntawv los ntawm kev sib tov ntawm Lavsan paj rwb thiab Lavsan-Len, tam sim no lawv tau txo me ntsis txo qis qis dua, txawm hais tias Lavsana tseem nyob hauv kev thov zoo.
- Txawm li cas los xij, rau xaws khaub ncaws hnav thiab ntaub pua txaj, cov ntaub so ntswg sib tov raws li polyester yog nce ntxiv. Cov fiber no muaj tib cov tshuaj lom neeg muaj pes tsawg leeg, tab sis ib qho sib txawv ntawm kev tau txais, thiab nws cov yam ntxwv tu thiab cov khoom lag luam zoo nkauj dua rau cov neeg siv khoom.
- Ntau nrhiav-tom qab yog cov ntaub, nrog rau Knitwear los ntawm kev sib xyaw ntawm Lavsan-thiab nyob rau tib lub sijhawm txaus muag, hygroscococicity thiab brearability thiab brearability thiab ua pa.

Yuav tu li cas rau cov khoom lagasan?
Txoj cai yog tias ua ntej ntxuav cov khoom, nws yog qhov tsim nyog los nyeem cov lus piav qhia ntawm textiles, uas yog polyethylene terephthalate yog tam sim no. Qhov kub ntawm kev ntxhua khaub ncaws thiab hlau yuav tsum tsim nyog rau tsawg kawg thermal tiv taus fiber ntau.
Raws li rau cov ntshiab Lavsan, nws hloov txhua lub tshuab ntxuav hom, txawm hais tias nws yog zoo kawg nkaus tso dej hauv dej sov. Txawm hais tias qhov tseeb tias qhov fiber ntau no yog qhov ruaj khov kho, kev siv tshuaj dawb yog tseem tsis muaj peev xwm. Cov ntaub ntawv thaum lub sijhawm ziab yuav tsum tau muag kom tsis txhob muaj kev zam ntawm cov ntaub ntawv pov tseg nyuaj, ironing cov ntaub so ntswg no tsis siab tshaj 140 degrees.
