Einflussfaktoren auf Garn Färberei

Garnfärbung unterscheidet sich von stricken Färben oder gewebt Färben. Während Färben, Textilingenieur sollte die ganze Arbeit nach Zeitplan tun und geben tiefe Besorgnis über jedes Verfahren. Bei etwaigen Störungen, dann wird es Einfluss auf die gesamte Färbeprozess haben. Die folgenden Faktoren sollten beim Färben berücksichtigt werden.

Stapel:
Dosieren sollte getan werden, um Baumwolle Strick-Gewebe und Jacquard-Strick-Gewebe.
Paket nach Drücken sollte vereinheitlicht werden.
Paket Kappe sollte fest sein bei Verlust während des Betriebs im Färbebad.

Druck:
Der Druck auf die gleiche Maschine sollte beibehalten werden. Wenn der Druck während der Färbung variiert, es wird auf dem folgenden Paket auswirken.
Der Druck sollte während in Prozesses beibehalten werden und aus.

PH:
PH ist einer der wichtigsten Faktoren beim Färben. Im folgenden wird der pH für die Baumwollstrickgewebe gehalten werden soll.
Nach dem Mischen von Salz: PH 6-6.5
Nach Soda Misch: PH 11-1.5. PH sollte nach dem Mischen Soda neutral sein

Überprüfen:

Was ist das das Prinzip der Verschiebung Rippe Kreis Strickmaschine und Punkt seiner Inbetriebnahme?

Erste, das Prinzip der Verschiebung Rippe Kreis Strickmaschine
Auf dem Schaltkreis Rippe Strickmaschine Kreis Schichtorganisation, die erste Spule sollte die Nadel auf dem Zifferblatt bewegen. Nadelkanäle in dem Zylinder, der Ausbau Ring mit dem Zungennadel Platte eingesetzt, Ausbau Ring aus Federstahlblech gebogen, wobei ein Ende davon ist an der Nadelstange befestigt ist, und das andere Ende nahe der Stricknadel Schienennut, und der andere dort Einschnitt (auch bekannt, Schulterstück) auf den Ausbau der Kreisstück.

Verschieben Ring auf dem Rechner installiert hat eine dreieckige Grundfläche und Rippennadelauswahlmechanismus ausschließlich für Moving Coil verwendet (Blume Scheibe, Chip setzen, Einsätze, Walze, usw.), die Notwendigkeit, die Nadel Kreis bewegen erhebt sich über den Ring zurück Lage. An dieser Stelle, Ausbau Kreisstück durchdringt die Spule, die Spule Expansion, und auf den Einschnitt Ruhe, gefolgt von den Nadeln auf der Scheibe nach außen (Rippnadeln kann auf die Position der Nadel steigen nicht Abheben ), durch die Nadelstange und dem Diffusor Ring aus Blech Hohlräume zusammengesetzt und bewegen Sie die Wahl Nadeln, die Zylinderspule auf den Stricknadeln gehakt. Mit dem Niedergang von Spritzennadeln, zwischen der Spule von der Spritzennadel Strickkreisstück Stange und verlängern die Lücke an der Rutsche. Wenn die Spritze Nadel sinkt weiter, die Maschen von den Nadeln der Nadelzylinder und ausziehen, und zu den Nadeln auf dem Nadelplatte zu diesem Zeitpunkt über, die Nadel der Nadel kein Spulen. Wenn die Nadel erreicht die nächste vor einem Kreislaufsystem (diejenigen), wenn die Spritzennadeln steigen, mittels der Zunge Öffner (auch als offene Nadel bekannt), die Nadel von der Zunge (das heißt, die Spule entfernt Spritzen die Nadeln Zungen) offen, bereit, weben.

Mit Schaltkreis weben Rippstrick-Organisation namens Schaltkreis, auch als Dreher bekannt. Es ist auf der Grundorganisation des Schuss basierend, nach der erforderlich ist, um etwas von der Ringspule verschieben Muster, die Spule, die von einem zum anderen Langreihe Maschenstäbchen über gebildet. Aufgrund der Art, das Gesetz Schaltkreis variiert, die Verwendung von verschiedenen Arten von Einrichtungen (flachen Nadeln, ineinander greifen, Rippengewebe) Weg-und Schaltkreis, Sie können eine Vielzahl von Mustern Effekte bilden (Muster) im Gestrick Oberfläche.

Zweite, die Schaltpunkte Rippe Maschine Debugging-Kreis
1 Verschiebung in der Sicherheitskreis Rippe Maschinenwartung, Hedge-Tuch (auch als Hängegewebe bekannt, Schnalle Tuch), Sie Stoffabdeckung auf der Nadel wählen müssen, die sich von anderen Strickmaschine. Der Grund dafür ist, dass die Spritze mit der Nadel Schnitt leicht süchtig zitiert Tuch, nicht einfach Abheben.
2 Öl ist nicht zu eng, setzen die entsprechende Länge des Spulenlänge. Der Hauptgrund ist, um in die Spule elastischen Dehnungsring Filme übertragen werden, Nadelmasche wächst rasant, Spannung verursacht Mutationen.
3 Wickelspannung nicht zu groß sein,, sonst anfällig für Löcher. Um den reibungslosen Ablauf zu gewährleisten Weben, Wickelspannungseinstellung sollte etwas kleiner als die anderen Produktspezifikationen sein.
4 Nehmen Verzögerung (nach dem Essen, asynchron) in einem Kreis, und beachten Sie die Wahl Nadeln Nadeldruck nicht zu tief, oder anfällig für Löcher.
5 Weben eines Fadenspannungskontrolle im Allgemeinen 4.9 ~ 7.84 cN (5 ~ 8 G) angemessen ist. Zu anfällig für Löcher, zu kleine Nadel anfällig für Leckagen.

Traditionellen Druck Another Way – Nachahmung Digitaldruck

20140726231658
Printing is the essence of flowers, flower attributed to fashion, digital technology has created a digital fashion development, and people turn to the pursuit of fashion Forced advances in technology. With the continuous development of digital printing technology, the traditional printing industry to further shocks. But it can not completely replace the traditional digital printing, then how reasonable arrangements between digital printing and traditional printing complementary, into new technology to enhance the point? Generally have the following observations and recommendations:

1, color digital printing on relatively poor. A large number of digital printing products are similar to the original work or imitation color. Can not be compared with the traditional color printing; does not specify a color for their customers, especially spot demanding customers.

2, high cost of digital printing, the loss is high. When digital printing process due to nozzle clogging, uneven friction fabric, wrinkles and the adverse higher, not completely mass production.

Given the status of traditional printing and digital printing, as well as the advantages and disadvantages of digital people for the pursuit of fashion, combined with digital printing and traditional printing, digital printing technology came into being fake!

Digitaldruck is an imitation of the digital inkjet printing technology with the perfect combination of traditional network-based application of new technology, which is different from traditional innovative use of spot color separations private network technology in the existing network platform printing technology, breaking the cycle of songs and limiting devices to be close to the cost and efficiency of the traditional printing digital printing printing comparable to the effect of, great to meet the consumer demand for digital fashion pursuit.
Imitation digital printing technology with printed fabrics, not only has the characteristics of low-carbon environment, the more important is the color change fabric richer, lifelike and vivid flowers. A three-dimensional fabric, especially for young people’s tastes. Andererseits, imitation digital printing in energy efficiency compared to ordinary printing to save a lot of value-added products is 3 zu 5 times digital printing.

Imitation digital technology to meet today’s dominant individual consumption. Now clothing fashion cycles are getting shorter, pattern changes more quickly, producing increasingly high demand, order smaller quantities. Cost and time consumed by conventional printing plate, no matter how it is difficult to meet the requirements of the modern trends in printing, digital printing and imitation has unique advantages in this regard.

Mittlerweile, digital printing has great potential in foreign markets. Europe is the biggest digital printing products, demand and production, digital printing has penetrated into apparel, home textiles, customization, and other fields. Small volume, Vielfalt, and rapid response mode greatly enhance the value chain clothing brand.

In short, digital printing as a revolutionary technological advancement for textile printing industry to bring endless vigor and vitality, but its price is expensive, especially nozzles, ink and other supplies not yet fully mature, operating costs are extremely expensive, and there is limited proofing small batch production, the real mass production also needs a little time to verify. The imitation of digital printing as a new means of digital printing technology, perfect make up the traditional printing and digital printing imperfections, suitable for mass production of digital flowers, flower power is not inferior to the performance of a digital direct injection and transfer printing, and bright colors degree, feel, color fastness, penetration is much better than the digital direct-injection and transfer printing, after all, a high-volume digital production orders.

Auswahl der Strickware Färbereihilfsmittel gemeinsamen Qualitätsprobleme

1. color fastness unqualified
Color fastness to light fastness, Waschechtheit, perspiration fastness, Reibechtheit, fastness to open China, ironing fastness, these fastness lies dye structural performance, but also with the fibers, dyes closely related to the concentration, dyeing and finishing processes, external conditions, so whether the target color fastness, the key is to choose the dye, followed by dyeing and auxiliaries applications.

When dyeing system permits must be based dyes, fibers and customer indicators reasonable assurance that the dye additives help, under certain conditions, as far as possible on the ground dye fastness fiber to make it fully fixed. For the additives, der erste, a good choice and pro-dye leveling agent, the dye slowly and evenly, fully dyeing fibers; Zweite, plus a chelating agent to overcome the dye and metal ions from the water floating color, and reduce hydrolytic activity of the dye in the water; Drittel, choose good soaping, go to the net floating color, and anti-floating re-stain fabric;; fourth is to select the appropriate fixative, the current sublimation fastness, sun outside fastness is no ideal fixative for soaping fastness, perspiration fastness collapse, the indicators rubbing fastness, usw.. are excellent fixative to choose from.

2. brittle damage
Brittle damage showed a strong decline in profit before oxygen bleaching due to improper handling and other processes cause damage or even brittle outer holes and other reasons, there are generally two types of brittle damage caused by dyeing reasons, one is brittle damage such as sulfur black dye caused required to improve the anti-brittle agent, as well as dyeing vat dyes and strong oxidizing agents strong reducing agents, such as damage to the fibers brittle; Second stage or the improper dyeing and stages with acid, and acetic acid is generally used, and currently on the market supply of some alternative acids, some of these alternative acids like BASF’s strong organic acid buffer, excluding sulfuric acid, hydrochloric acid, phosphoric acid, and even superior performance than acetic acid, the chemical company Ningbo Runhe buffer acid is also true these buffer acetic acid but also to improve some of the shortcomings (such as glacial acetic acid winter inconvenient to use, stimulating taste great, residual acidity, and metal ions in water such as Ca +2 Mg +2) remain in the fabric caused by the combination of dark shade wilt etc. usw.). Some with H2SO4, HCl, H3PO4 and other alternative acid, not only cause changes in dyeing shade, dyeing and finishing equipment and pumps for corrosive effect, but during and after the acid residues can also cause fabric damage brittle under acidic conditions.

3. Wrinkle Article
Wrinkles are generated mainly of equipment reasons, the amount of cloths has installed causes the bath ratio and the processing operation of the reasons and other reasons, the amount of fabric mounted equipment, the pressure and friction between the pump power and the tension of the fabric and the fabric are affected fabric cloth flatness; bath ratio will affect the size of the flatness of canvas; process operations caused by too much fabric floating foam additives and process skid heating and cooling operation appears cold and hot phenomenon will cause fine wrinkles of the phenomenon . The current bath lubrication wrinkle agent, bath treasure, bath softener can improve fine wrinkles of the phenomenon, but if the device does not improve, poor process control, plus bath lubricant alone can not completely avoid the fine wrinkles of produced.

4. Wind India
Air India has little to do with the additives, the key is to dye their own performance (acid resistance) and fabric with pH, acid gas air humidity and so on, such as direct dyes Fast Turquoise Blue GC, chrysophenine G, usw.. in case of sour gas prone to wind and India; activity in Turquoise Blue KN-G, brilliant orange X-GN and other pH sensitive and easy to produce on wind India; dyes such as yellow RGFL in base-sensitive, but also easy to produce wind India . For aid, the middle and must do to make cloth as pH = 7. Deshalb, attention must also breed and when acids and bases, as far as possible with glacial acetic acid or organic acid substitution, can never substitute acid containing H2SO4, HCl and other strong inorganic acids, bases with Cheung also choose to ease as much as possible Some.

5. color flowers (including color, color does not match the sample, usw.)
Flower color dyeing process is the most common, the most common quality problems, the causes are:
(1) the development and operation of process issues: developing technology to produce an unreasonable or improper operation flower color.
(2) equipment problems: If the disperse dye polyester heat-setting machine inside the oven temperature varies also easy to produce color-color flowers, dyed rope pump power shortage also cause colored flowers.
(3) Dye problem: dye aggregation prone, poor solubility, poor compatibility, Temperatur, pH is too sensitive and are easy to produce color flower color. Reactive Turquoise Blue KN-R as easy to produce colored flowers.
(4) water quality problems: poor water quality, causing the dye and metal ions or dyes and impurities caused by condensation flower color, light color, the color does not match the kind of phenomenon.

Problem with colored flowers are mainly related to penetrant additives, leveling agents, chelating dispersant, pH value control agents penetrant penetration enough, could easily lead to uneven color dye penetration flowers, such as casual cotton dyeing, cheese dyeing effect, heavy fabric dyeing, penetrant can not be ignored, and some believe only authentic factory penetrant JFC, but did not take into account the cloud point JFC only 38-42 ℃, More than 42 ℃, its penetration force it to play out, will cause quality problems. There leveler with polyester, cotton with wool, nylon used, with all kinds of acrylic leveling agent, and the quality is uneven, leveler selection must take into account the effect of dispersing the dye solubilization, retarding migration effect, Help osmosis or complexation of metal ions in water, and must take into account various factors which PH applicability, foam and other effects on the rate of color. Leveler to improve the color of flowers, color point and so contributed, some plants leveler just solution diffusion agent N, but did not think the proliferation of agents N at a high temperature resistant dyes its unifying role greatly reduced; there the plant selection nonionic surfactants are not suitable, resulting in more than the cloud point nonionic surfactant itself precipitated dye adsorbed from tarry substance or apparatus into the fabric, but cause quality problems. Quality chelating dispersant leveling problems are related, in the current water quality is getting worse, the chelating dispersant leveling should help more attention. pH control problem is a problem of the plant too seriously, pH and some plants are not the same for each cylinder stained, with some plants using different acid substitution of quality, such as containing phosphate, pH phosphate are three ionization there are differences in how to control a uniform pH: pH slip agents using some plants, but not such as to grasp the relationship between the pH and the temperature and time generated between the slip agents, pH control of the question, so that the flower color, the phenomenon of color continue to produce.

6. color point (including white point)
The reason there are many color points generated, such as white spots, may be non-mature cotton is not the cause of the dye, it may be caused by the local soda ash and other solid stick and other reasons not to dye the cloth. Color point is the main reason:
(1) Dye inappropriate choice: dye particles are too large or easy to produce condensed color point;
(2) performing a dye dissolved: not dissolved dye into the fabric from sticking to the dye color point;
(3) water quality is poor: poor water quality caused by dye condensation;
(4) the device without a net: vat of tar-like substance under the swap cause color point;
(5) Auxiliary Reason: added in dyeing auxiliaries sometimes cause the dye to produce color point but agglutination; aids too much foam, foam with a colored dye binding bubbles stick to the fabric to form color point; additives and dyes precipitate combined with the device sticks to the fabric, and agglutinates will turn the device on the color point of the dip caused by the fabric.
