Proses van Mercerizing breistowwe

Mercerizing is 'n bykomende proses wat die fisiese en chemiese eienskappe van kan verbeter breistowwe. Vir klere breistowwe, mercerizing voor klere. Gemerseriseerde materiaal is meer geskik as unmercerized materiale. Mercerizing hang af van die kopers se vereistes, Dit is nie algemeen vir katoen. Dit is gedoen vir die gesofistikeerde materiaal. Die masjien is vertikale tipe wat bestaan ​​uit vertikale wasgoed kamer.

Tipes mercerizing proses: Drie fases van die produkte kan mercerizing neem
>Grey mercerisasie (Breistowwe voor klere)
>Stof mercerisasie (Gare gekleur stof)
>Kraag & Cuff mercerisasie.

Frekwensie van mercerisasie: Mercerizing kan in enkele mercerisasie en dubbel mercerisasie geklassifiseer word.

Proses van mercerizing breistowwe:
1)Stof wat in mercerizing masjien
2)Bevrugting in reaksie kamer

Hidro Extractor masjien vir klere breistowwe

Hydro extractor machine is the first sequence of dyeing breistowwe. After dyeing being completed, knitted fabrics are hold for a while before hydro extraction. Hydro extractor machine is vital for de-watering process.

Functions of hydro extractor machine: Hydro extractor machine uses centrifugal extraction to remove excess water from knitted fabrics. Oor 65% water is removed by hydro extractor machine which spends 5-10 minute.

Procedure of hydro extractor machine: Hydro extractor machine looks like a round basket which is made of steel. It has amount of holes on the down side of basket. Put the wet knitted fabrics into the hydro extractor, then water is removed by centrifugal extraction. Extract water is drained out through the holes.

Deesdae, various types of hydro extractor machine are available in the market. People can choose what they need according to their own requirements.

Proses van vervaardiging breistowwe

Knitting is the interlocking of one or more yarns through a series of loops which is the main activities for producing breistowwe. In every mill, a sequence is maintained in production processing. In every step, person should be responsible for the best production. The followings are the process of manufacturing knitted fabrics.

Eerstens, a production is supplied to knitting manager from the merchandiser, according to the requirements of consumers. Then he informs or orders production officer about it and provides the schedule for producing targeted production.

1. Getting the analysis from knitting manager, design and draw a cam setting for producing the desired fabrics.

2. Getting the information, production officer informs technical who is in charge and knows about machine which the production will be run.

3. Technical in charge calls for leader of mechanical fitter troops who also take decision about machine for production considering machine condition, machine types, production capacity and maintenance complexity.

4. Production officer adjust required stitch length and grey G.S.M for getting final G.S.M., cooperating with experienced mechanical fitter.

5. Supervisor checks production regularly and makes operator consciously about finishing tin due time who is also maintain daily production report sheet and responsible to inform the production of that day to knitting manager.

6. Operator runs machine in high attention in case of faults in the fabrics. Any faults are found, he will call for the mechanical fitter who is in duty. Toe, mechanical fitter fixes it or informs it the technical in charge. The technical will take necessary to remove the problem.

7. During production time, quality department also checks the fabric. If any faults are found, they will inform it to the technical in charge. Technical also takes necessary steps for reducing the faults in knitted fabrics.

8. When knitted fabrics completed, knitted fabrics will be sent for quality check. If the fabrics pass the quality, they will be sent for the next process.

Definisie en tipes breistowwe

Stof are produced from a set of warp or weft yarn. Weaving and knitting differ for interlacing techniques of yarn. In weaving, warp and weft yarn are used for producing woven fabric. For knitting, a series of yarn in warp or weft directions are made of fabrics.

Knitting is defined as the process that sets connect loops from a series of yarn in warp or weft direction to produce fabrics. Various knitting machines are used to perform knitting. In die algemeen, breistowwe are classified into warp knitted fabrics and weft knitted fabrics.

Warp knitted fabrics: In warp knitted structure, different thread and the number of thread is made of each loop in the horizontal direction. Fabric is at least equal to the numbers of loops in horizontal row.

Weft knitted fabrics: Use one thread runs in horizontal direction to make a horizontal row of loops. The structure of weft knitted fabrics is different from that of warp knitted fabrics. Weft knitted fabrics have worldwide popularity.

In daily life, different knitted fabrics are used. Depending on the design of fabrics, knitted fabrics are classified into following types.

5. Race Collar
6. Stripe Collar

Knitting machines also develop various types of decorative design. In modern times, auto stripe knitting machine is used to produce multi color stripe fabrics, which cannot be produced by normal knitting machine.

Breistowwe have different properties. Knitted fabrics depend on the atmospheric condition of the country.

Foute van breistof in Produksie

Loop formation produces gebreide materiaal which should be careful. Various types of faults can be found in knitted fabric, which caused by fabric rejection. Find out defects of fabric during production. Toe, steps can be taken to remove them from the next knitting production process.

In practical: The followings are the faults which could be found on the knitted fabric.

Hole Mark
Reasons:
>The yarn breaks in the rejoin of the needle hook during loop formation.
>Caused by yarn breakage or cracks.
>The yarn is not correct on regarding structure, meter, course and density.
>Badly knots or splicing.
>Badly set of yarn feeder.

Needle Mark
Reasons:
>Needle marks come along the fabrics when a needle breaks down.
>If a needle or needle hook is slightly bends, then needle mark comes on the fabrics.

Star
Reasons:
>Buckling of the needle latch.
>Yarn tension variation during production.
>Low G.S.M fabric production.

Sinker Mark
Reasons:
>Sinker may corrode for abrasion. So it cannot a new loop and result in sinker mark coming.
>Sinker head bends. Then sinker mark comes.

Drop Stitches
Reasons:
>Yarn is not feed properly during loop formation.
>Using defective needle.
>Take down mechanism is too loose.
>Insufficient yarn.
>Set yarn feeder badly.

Oil Stain
Cause:
>When oil lick through the needle trick then it pass on the fabrics and make a line.

Rush Stain
Reasons:
>Rush in the machine.

Pin Hole
Reasons:
>Break down or bend of the larch causes pin hole on the fabric.

Grease Stain
Reasons:
>Improper greasing in the machine.
>Excess IF greasing

Reasons:
> when an empty needle with an empty needle with close latch runs into the yarn feeder and remove the yarn out of the hook of the following needles, then cloth fall out occur after a drop stitch.

Barre
Reasons:
>Yarn fault
>Different micro near value of fiber content in yarn.
>Different luster and dye affinity of fiber content in yarn.
>During spinning different similar classes of fiber is mixed specially in carded yarn and these fibers have similar characteristics.
>In draw frame different similar classes sliver is mixed and make one sliver.

Yarn Contamination
Reasons:
>Yarn contains foreign fiber. And the foreign are remained in the fabric even after finishing.
>Lot mixing and count mixing.

Fly Dust
Cause:
>In brei artikel te veel pluis of kort vesel vlieg heen en weer wat geskep word van draad as gevolg van lae draai asook draad wrywing. This lint may adhere or attached to the fabric surface tightly during gebreide materiaal vervaardiging.

Yarn Faults
Reasons:
>Different yarn faults
>Neps
>Slubs
>Yarn count variation
>Thick/Thin place in yarn
>Hairiness

Knitted machine should have perfect conditions. Faults are not allowed to exist in needle, sinker, feeder and other equipments.

Silk Saamgestelde Air laag gebreide materiaal produksie proses

Sy gebreide produkte nie net met die vog, breath, liggewig, gesondheid en ander eienskappe, en beter as geweef kant rek, anti-rimpel weerstand en wasbaar.

Tans, die mark is meer gewild saamgestelde lug laag termiese onderklere weefsel van katoen en chemiese vesel hoofsaaklik gebaseer grondstowwe, relatief klein kant materiaal, waarvoor die ontwikkeling van 'n reeks komplekse lug laag met sy stof, hoofsaaklik uit die kern materiaal verwerking, weefproses, verf proses verbetering en innovasie aspekte van die produk deur die verbruikers.

1. Pilling bestand kern materiaal verwerking

Core algemene lug laag stof wat gebruik sonder anti-Pilling behandeling tydens die dra as gevolg van wrywing, statiese elektrisiteit en ander redes, die kern materiaal is maklik om te boor, vorming van 'n strook van sy draad, ernstige gevolge vir die neem effek. In reaksie op hierdie situasie, op die basis van die verlede rek netwerk verwerking van tegnologie, anti-Pilling kern verwerking uit te voer, maar raak nie die kern materiaal krimp en donsig op die basis van die kern materiaal verwerk deur die netwerk as gewone gare beter lywigheid.

Filament interlacing Shuli lug uit die “pigtail” artikel, waar glad nie deel nie die weef beïnvloed, terwyl die onbetaalde gedeelte van die elastiese vesel netwerk deur die lug opening, lei tot 'n beter sagte, met meer goeie warm effek. Verwerk deur aanmekaargestrengelde rek sy met 'n goeie samehorigheid van die poskantoor netwerk, onder die gewone krag, verskeie rek is nie maklik om te verloor. Plus toepaslike organisatoriese weef, oorkom die gemeenskaplike kern draad is maklik rek fluweel te boor, sydraad van gebreke.

2. weefproses

Omdat sy tekstuur eerder hard, taaiheid en buig weerstand, is meer geneig tot foute as die gemiddelde van die draad in te weef, soos driehoekige oë, doek en ander onreëlmatighede. Probleme kant weef brei proses wat die proses van spanning beheer, te maklik om te val af, dit sal te veel slytasie op die loom dele veroorsaak, olie is ook maklik om te pluis. Deur voortdurend aanpassing van die masjien, vergelyk die beste weef proses gekies, die volgende lug laag van kant reguit byvoorbeeld.

'n) Toestel Parameters

Masjien No: 28-pen /25.4 mm

Tube deursnee: 762.0 mm (30 “)

Grotes: 72 F

b) Materiaal seleksie

Stof oppervlak en die binneste laag is gekies vir 4.4 / 4.9 tex kant × 2 (40/44 D × 2), die kern seleksie 22.2 tex (200 D) polyester.

c) threading af

24 F vir 'n lus, die eerste 1,4,7 … 22 F spuit vol in die ring, penetrasie 4.4 / 4.9 tex × 2 kant; Artikel 2,5,8 … 23 F inbel naald in die hele sirkel, ooreenstemmende opgestel patroon by spuit naald op × snoepie, penetrasie 4.4 / 4.9 tex × 2 kant; artikel 3,6,9 … 24 F ooreenstem met die patroon opgestel × snoepie by spuit naald, penetrasie 22.2 tex polyester.

d) opgestel patroon

Die artistieke konsepsie getoon in figuur 2.

Figuur 2 opgestel patroon

Flower breedte van 12 vertikale lyne, blomme hoog as agt kursusse. Road fietsry is 24 grotes, omdat die gebruik van 28-pen /25.4 mm masjien-geweef, meer delikate weefsel, stof patrone ten einde die effek meer prominent te maak, gebruik dieselfde naald vir twee agtereenvolgende pen snoepie. Polyester alleen al die pad in en snoepie by 'n sirkel, dus die vermindering van die polyester in die middel van die beweging van Pilling te vermy, Pilling. Die stof resultate in figuur 3.

Figuur 3 materiale positiewe uitwerking diagram

en) draad spanning aanpassing

Omdat sy het 'n goeie taaiheid, kant weef die spanning te beheer. Spanning te veel masjien en breinaalde oormatige slytasie veroorsaak, te val af wanneer die opbrengs van sy gare, sy algemene spanning beheer op 3.92 ~ 5.88 ciV toepaslike. Polyester garen spanning so klein as moontlik, die algemene beheer 1.96 ~ 2.94 ciV toepaslike.

f) lap aanpassing

Wanneer weef, As die spanning is te klein doek, doek maklik dryf, nie normaalweg 'n sirkel, doek moet toepaslik verhoog spanning, maar nie te veel, te veel spanning op doek geneig om gate te oorgedra word stof vorming geen gat seëvier.

h) aangepas met die cam silinder en bel cam

Omdat sy het 'n goeie taaiheid, weef die stof oppervlak is maklik om te pluis, sodat die spuit en naald plaat driehoek driehoek aan te pas by hulle naald en spuit naald te skakel in die ring op dieselfde tyd, hierdie kant in die garing spanning is relatief stabiel, nie geneig gat.

3. Kleur en afwerking

Na die lug laag saamgestelde stof weef, maar ook na die skuur, kleur, omgewing en ander afwerking. Wanneer die een kant van die stof klere binnekant na buite, om te verhoed dat skuur die voorkant, in orde te handhaaf 'n positiewe en 'n gladde. Met suur kleurstowwe, beheer tyd en temperatuur skuur, kleur spoed drie of meer te bereik.

Yarn Voorbereiding vir stof brei

Yarn gebruik vir brei kon grys of gekleur word nie. Yarn is die hoof rou materiaal vir stof brei. Yarn moet bereid wees om vir die brei. Dit kan nie in direk gebruik word nadat hy versamel van spin. Die maniere waarop proses draad voor loom as garen voorbereiding genoem. Eienskappe van brei meestal afhanklik van die garen voorbereiding.

Noodsaaklikheid van die draad voorbereiding: Verskeie maniere word gebruik vir die voorbereiding van garings. Die opeenvolgende is die noodsaaklikhede van die draad voorbereiding.

1. Yarn voorbereiding proses kan uitskakel defekte van garings.
2. Voorbereiding oordra garings van spin pakket na 'n gerieflike vorm van die pakket wat fasiliteite die brei.
3. Maak die draad vir 'n beter voorkoms en prestasie.
4. Het verlangde lengte van die draad in die pakket.
5. Kry stof wat 'n beter gehalte.
6. Elimineer ongewenste stof en harige vesel.

Yarn voorbereiding speel 'n belangrike rol vir die brei weefsel.
