IINGCEBISO:

Ukuhlelwa kwezinto ezigqityiweyo

Iinkqubo zokugqiba zinokuhlelwa ngokubanzi zibe ngamaqela amabini:

(a) Okomzimba okanye koomatshini

(b) Imichiza.

Iinkqubo zomzimba okanye zoomatshini ziquka iinkqubo ezilula ezinjengokomisa kwisilinda esifudunyezwe ngumphunga kwiintlobo ezahlukeneyo zeekhalenda, ukuphakamisa iziphumo ezithambileyo kumphezulu welaphu kunye nokwaphula ukugqitywa kwempahla egcweleyo ukuze uzive ukhululekile.

Uninzi lokugqiba oomatshini luyaziwa ukususela kumaxesha amandulo kwaye utshintsho oluthile lwenzeke kwindlela yabo yokusebenza.Ezinye iimpawu zomzimba, ezifana nokuzinza kwe-dimensional, zinokuphuculwa ngokugqitywa kweekhemikhali.

Ukugqitywa koomatshini okanye 'ukugqiba ukomisa' kusebenzisa ubukhulu becala (ingakumbi oomatshini) kuthetha ukutshintsha iimpawu zelaphu kwaye kudla ngokuyitshintsha inkangeleko yelaphu ngokunjalo.Izigqibo zoomatshini ziquka ukulinganisa, ukuvela, ukucutha okucinezelayo[1] ubudala, ukunyusa, ukubrasha nokucheba okanye ukunqunqa.Ukugqitywa komatshini kumalaphu oboya kukusila, ukucinezela kunye nokusetwa ngoononkala kunye nokuqhawulwa.Ukugqitywa komatshini kukwabandakanya iinkqubo ze-thermal ezifana nokumisa ukushisa (okt, ukugqitywa kwe-thermal).Ukugqitywa komatshini kuthathwa njengomsebenzi owomileyo nangona umswakama kunye neekhemikhali zihlala zifuneka ukuze kuqhutywe ngempumelelo ilaphu.

Ukugqitywa kweekhemikhali okanye 'ukugqiba okumanzi' kubandakanya ukongezwa kweekhemikhali kwizinto ezilukiweyo ukuze kufikelelwe kwisiphumo esinqwenelekayo.Ekugqityweni kweekhemikhali, amanzi asetyenziswa njengendawo yokugalela imichiza.Ubushushu busetyenziselwa ukuqhuba ngaphandle kwamanzi kunye nokwenza imichiza isebenze.Iindlela zemichiza zitshintshile ngokuhamba kwexesha ngokumangalisayo, kwaye ezokugqibela zintsha ziphuhliswa ngokuqhubekayo.Iindlela ezininzi zeekhemikhali zidibaniswe neendlela zomatshini, ezifana ne-calendering, ukuphucula umphumo.Ngokuqhelekileyo, ukubonakala kwe-textile akutshintshi emva kokugqiba imichiza.

Ezinye izigqibo zidibanisa iinkqubo zoomatshini kunye nokusetyenziswa kweekhemikhali.Ezinye izinto ezigqitywa ngoomatshini zifuna ukufakwa kweekhemikhali;umzekelo, ii-arhente zokugaya ziyafuneka kwinkqubo epheleleyo okanye i-reductive kunye ne-fixation agents ukwenzela ukushwabana amalaphu oboya obungqina.Ngakolunye uhlangothi, ukugqitywa kweekhemikhali akunakwenzeka ngaphandle koncedo lomatshini, njengokuthuthwa kwendwangu kunye nesicelo semveliso.Isabelo sokugqitywa komatshini okanye kweekhemikhali kuxhomekeke kwimeko;oko kukuthi, nokuba icandelo eliphambili lenyathelo lokuphucula ilaphu lisebenza ngoomatshini okanye ngemichiza.Izixhobo zoomatshini zisetyenziswa kuzo zombini iindidi;Umahluko omkhulu phakathi kwezi zimbini yintoni ebangele ukuba ilaphu elinqwenelekayo litshintshe, ikhemikhali okanye umatshini?

Enye indlela yokwahlulahlula kukwahlulahlula izinto ezigqityiweyo njengezexeshana nezisisigxina.Enyanisweni, akukho siphelo simi ngokusisigxina de izinto zisebenze;kungoko ulwahlulo oluchaneke ngakumbi lunokuba lolwexeshana okanye lomelele.

Ezinye zezinto ezigqityiweyo zexeshana zezi:

(a) Ubuchwephesha: ikhalenda, i-schreinering, i-embossing, ukukhenkceza, ukwaphula, ukuzolula, njl.

(b) Ukuzaliswa: isitashi, udongwe lwaseChina kunye nezinye izizaliso zezimbiwa

(c) Ukusetyenziswa komphezulu: i-oyile, izithambiso ezahlukeneyo kunye nezinye izinto zokugqiba.

Ezinye zezinto ezigqitywe ixesha elide zezi:

(a) Umatshini: ukushwabana okucinezelayo, ukuguba koboya, ukunyuswa kunye neenkqubo zokusika, ukusetwa kwe-perma[1]nent, njl njl.

(b) I-Deposition: ii-synthetic resins-zombini ngaphakathi nangaphandle, i-raber latex, i-laminating, njl.

(c) Ikhemikhali: i-mercerisation, i-perchmentising, i-agent edibanisa ukudibanisa, ukugqitywa kwamanzi, ukumelana nomlilo kunye nokugqitywa komlilo, ukushwabana kobungqina boboya, njl.

Kufuneka kuqatshelwe ukuba naluphi na ulwahlulo olunjalo alunanjongo.Ukuhlelwa ngokuchanekileyo kunzima kuba ukuqina kuxhomekeke kwizinto ezininzi.Ukuqina kunokwahluka, kwaye akunakwenzeka ukuzoba nawuphi na umda phakathi kokugqitywa kwexeshana kunye nokuqina.

Iinkqubo zokugqiba zihluke kangangokuba kunzima ukuzihlela.Kwi-cot[1]itoni, iinkqubo ezininzi zokugqiba zisetyenziswa ngokubanzi, kodwa zahlukene ngokobuchule kangangokuba kunzima ukuzihlanganisa kunye.Kwiminyaka emininzi, iinkqubo zokusasazwa, ezizezi, i-mercerisation kunye ne-perchmentization, yayikuphela kwesiphelo esisisigxina kwikotoni, kwaye zisabaluleke kakhulu namhlanje.Iikhemikhali eziqhelekileyo ezisetyenziselwa ezi zigqityiweyo ziyi-caustic soda kunye ne-sulfuric acid, ngokulandelanayo, kwifom egxininiswe ngokulinganayo.
