Dyes yog cov xim organic sib txuas uas tuaj yeem dye fibers lossis lwm yam substrates rau hauv ib qho xim. Lawv tsuas yog siv rau hauv dyeing printing ntawm yarns thiab fabrics, tawv dyeing, ntawv dyeing, zaub mov additives thiab yas colouring teb.Raws li lawv cov khoom thiab daim ntawv thov txoj kev, dyes yuav muab faib ua disperse dyes, reactive dyes, sulfide dyes, VAT dyes, acid dyes, ncaj dyes thiab lwm pawg.
Kev lag luam loj hauv keeb kwm yog feem ntau cuam tshuam nrog tus nqi zas xim, thiab tus nqi zas xim feem ntau yog nce thiab poob nrog cov khoom siv raw khoom raws li cov khoom siv thiab kev xav tau kev sib raug zoo txiav txim siab, muaj lub zog tsis muaj zog ntawm lub caij nyoog ntawm ib xees.

Kev lag luam sab saud ntawm dyestuff manufacturing kev lag luam yog kev lag luam petrochemical, kev lag luam tshuaj lom neeg thiab kev lag luam thee. Cov ntaub ntawv tseem ceeb ntawm dyestuff yog benzene, naphthalene, anthracene, heterocycles thiab inorganic acid thiab alkali thiab lwm yam khoom siv tshuaj. Kev lag luam downstream yog luam ntawv thiab dyeing kev lag luam hauv kev lag luam textile.

Dye intermediates tuaj yeem muab faib ua benzene series, naphthalene series thiab anthracene series raws li lawv cov qauv, ntawm cov benzene series intermediates tau dav siv.Ntawm cov benzene intermediates, m-phenylenediamine thiab reductants yog cov ntaub ntawv tseem ceeb rau kev sib txuas ntawm disperse dyes, thiab para-ester yog qhov tseem ceeb intermediates ntawm reactive dyes. Ntawm lawv, m-phenylenediamine kuj tseem tuaj yeem raug ntxiv rau hauv m-phenylenediamine (tsuas yog siv los ua cov ntawv khi rau lub log qaum impregnation) thiab m-aminophenol (kub / siab rhiab zas xim.

Intermediates).Naphthalene intermediates, suav nrog H acids, yog cov tseem ceeb raw cov ntaub ntawv rau zus tau tej cov reactive dyes, accounting rau 30-50% ntawm tag nrho cov nqi. Tsis tas li ntawd, cov intermediates rau synthesis ntawm anthraquinone dyes yog tsuas yog 1-amino-anthraquinone. , uas belongs rau anthraquinone system.

Porter lub tsib lub zog tsom xam ntawm kev lag luam dyeing 1. Lub hwj chim ntawm cov khoom siv hluav taws xob sab saud yog qhov tsis muaj zog.Cov neeg muag khoom ntawm cov khoom lag luam dyeing yog benzene, naphthalene thiab lwm cov khoom siv roj av thiab petrochemical khoom. Qhov kev thov ntawm kev lag luam dyeing rau roj av thiab petrochemical cov khoom lag luam yuav luag tsis pom zoo piv nrog rau lwm cov kev lag luam. Yog li ntawd, kev lag luam dyeing yog tus tau txais cov nqi ntawm cov khoom siv roj av thiab cov khoom siv roj av.

2. Muaj zog bargaining hwj chim rau downstream cov neeg muas zaub.Cov downstream cov neeg muas zaub ntawm cov dye kev lag luam yog mas luam ntawv thiab dyeing lag luam. Lub zog sib cog lus muaj zog ntawm kev lag luam dyeing rau cov neeg siv khoom qis qis yog vim ob qho laj thawj. Ua ntej, qhov concentration ntawm kev lag luam dyeing yog tsawg heev. Thib ob, nyob rau hauv tus nqi ntawm printing thiab dyeing dyes accounted rau ib tug kuj me me, luam ntawv thiab dyeing tuam txhab uas muag rau dyeing nqi nce yooj yim txais.

3. Ob peb muaj peev xwm nkag tau rau hauv kev lag luam.Vim patent technology, cov ntaub ntawv tseem ceeb thiab kev tiv thaiv ib puag ncig, kev lag luam dyestuff muaj teeb meem siab, thiab kev nthuav dav ntawm kev tsim khoom raug txwv. Nyob rau hauv xyoo tas los no, rov qab me me muaj peev xwm tau raug tshem tawm thaum ob peb tus neeg tshiab tau nkag mus. Yog li ntawd, yav tom ntej dye kev lag luam siab concentration qauv yuav ua tau mus ntxiv.

4. Cov khoom hloov pauv ua rau muaj kev hem thawj me ntsis.Foreign dye giants positioning high-end khoom lossis tshwj xeeb dyes tsis ua rau muaj kev hem thawj rau kev lag luam hauv tsev. Tsis tas li ntawd, cuam tshuam los ntawm tariffs thiab freight, ntshuam nqi kuj yog siab heev.Yog li ntawd, dye substitutes ua rau muaj kev hem thawj me ntsis.

5. Kev sib tw ntawm kev lag luam nruab nrab.Tom qab kev sib koom ua ke loj ntawm kev lag luam los ntawm 2009 txog 2010, tus naj npawb ntawm cov lag luam tau poob mus rau ntau tshaj 300. Nrog rau kev sib sib zog nqus txuas ntxiv ntawm kev hloov pauv hauv lub teb chaws, qhov concentration ntawm cov Kev lag luam dyeing tau zoo zuj zus lawm.Lub peev xwm ntawm cov khoom siv hauv tsev yog cov concentrated hauv Zhejiang Longsheng, Leap Av Tshuag thiab Jihua Group, CR3 yog li 70%, reactive dye muaj peev xwm ntau dua hauv Zhejiang Longsheng, Leap av Tshuag, Hubei Chuyuan, Taixing Caragian thiab Anoki tsib lub lag luam, CR3 yog ze li ntawm 50%.
Kev soj ntsuam qhia tau hais tias usher nyob rau hauv ib lub sij hawm ntev tawm ntawm lub caij apparel lag luam ncaj qha thawb tus nqi ntawm disperse dyes.Disperse dub ECT300% dye nqi tau nce 36% nyob rau hauv ob lub hlis dhau los.

Hais txog qhov kev thov, vim muaj kev cuam tshuam ntawm kev sib kis, ntau lub tuam txhab xa khoom loj-taw qhia kev lag luam textile hauv Is Nrias teb tau hloov ntau qhov kev txiav txim rau kev tsim khoom hauv tsev nyob rau lub hlis tsis ntev los no vim tsis muaj peev xwm lav tau tus me nyuam ib txwm vim muaj kev sib kis. Ntxiv rau, "ob npaug 11 ″ tab tom los txog, kev lag luam e-lag luam ua ntej kev txiav txim, Tshuag yog tus yuam sij kom yeej kev lag luam. Ntxiv rau lub xyoo no "lub caij ntuj no txias" xav tau, kev lag luam hais tias textile tuam txhab lag luam tshwj xeeb tshaj yog tam sim no.Tshaj tawm cov dyes kuj tau nce. sharply teb.

Hais txog kev muab khoom, qhov xwm txheej hnyav ntawm kev nyab xeeb thiab kev tiv thaiv ib puag ncig hauv Suav teb tuaj yeem txuas ntxiv mus ntev rau yav tom ntej vim muaj kuab paug loj los ntawm kev tsim cov dyes thiab intermediates, thiab cuam tshuam txog kev nyab xeeb thiab kev tiv thaiv ib puag ncig tsis muaj peev xwm ntau lawm thiab tsis muaj txiaj ntsig. Lub peev xwm ntau lawm yuav maj mam tshem tawm.Guoxin Securities tau hais tias cov chaw lag luam me me disperse dye ntau lawm muaj kev txwv ntau lawm, qhov xwm txheej tam sim no yog qhov tsim nyog rau kev tsim cov xim ua lag luam.
