Color difference is one of the difficult things to troubled our dyeing workers frequently, however the reason to cause the color difference is too many, below let us tell you how to control color difference on every processes in our factory： 1. Grey cloth detection stage It's very important to detect the Grey cloth: we should not only inspect width/ density of warp and weft, but also to check the outer quality of fabric ( such as weaving defection/ stain etc), we will mark the Grey cloth with different time, on dyeing we try best to use one batch fabric to dyeing same color, if we use different batch fabric, we should mark on the card, in case of any batch difference. 2. Fabric pre-treatment stage Grey cloth need to though pre-treatment, to improve the dyeing property. Pre-treatment is one of the main reason to cause width difference: boiling time/ temperature/ concentration/ scouring pressure control are the most important things, especially the detection of concentration which need professional person. Moreover, washing temperature also should be noticed, cannot lower or higher. 3. Dyeing stage Dyeing is also one of the main reason to cause the color difference. Generally padder pressure uneven/ oven width temperature difference is one of the main reason to cause color difference, dye vat width indicator difference also cause the aberration. Dye liquor on the dye vat didn't reach dynamic condition is also the reason to cause dye difference in the head and the tail of Grey cloth. If dyeing on the jig dyeing machine, we will put dyestuff / auxiliaries , especially the dye stuff against alkali. 4. Finishing stage Generally, if exclude above three possible reasons, you should to check sizing machine, because sizing machine 's pressure uneven, especially light color variety, will cause aberration. 5. Equipment selection Different equipment tension, and water pump lift strength will cause aberration. 6. Personnel selection Operator's skill higher or lower will also effect the textile's aberration, so we always choose higher skilled / higher quality / better operator to handling the equipment.

Will bleach or RIT color remover work better for removing color from striped cotton fabric before dyeing a solid color?
RIT...I swear by it. It's not as cost effective but works much better than bleach. It doesn't leave blotches or yellow stains like bleach. And because it dissolves in the water, it applies more evenly to the fabric. I actually use it when my solid whites start to look dingy. GOOD LUCK
How do fabric dyes work?
it stains the fabric the dyes color
Is dyeing hair a chemical change?
no it is a color dye added to the dead cells that are your hair.
What is the Dyeing Basic Principle of Flame Retardant Fabric?
The dyeing is a process to make the fabric lustrous according to the dye together with flame retardant fabric through chemical or physical chemistry way. Once the dyed flame retardant fabric colour fading, the fabric has been redyed if you want the fabric recover the original color. The flame retardant fabric dyeing process including surface adsorption, internal divergence and dye fixation.1, Surface adsorptionThe dye will be adsorbed the fiber surface when dipped the fiber to the dye liquor, this is the initial stage of the dyeing process. Good appetency and high concentration dye together with moderate electrolyte will increase the fiber adsorption speed, which will help to make the dyeing pricess correctly.2, Internal divergenceThe dye will be diffused to the fiber interior after the dye adsorbed to the fiber surface. This process is the longest stage in the whole dyeing process. In the dye liquor, the fiber surface dye spreads to the low concentration fiber interior, makes the dye added to the fiber surface continuous, until the fiber dye strength same as the dye strength in the dye solution. After transformation finished, the dye adsorption finished on the fiber surface. So, adsorption and diffusion are the inalienable and simultaneous process.3, Dye fixationThe dye adsorb, diffuse and permeate to the fiber surface and interior, and also fix on the fiber with all kinds of chain, the dye and fiber are diffrent, so as the fixation style, and because of the different fixation style, so as the dye fastness.By YULONG FR tex
How does dye affect fabric?

Can you give me a sentence for the word dyeing?
To dye something is to color something (usually cloth or fabric) by soaking it in some sort of liquid. For instance: The mother was dyeing the shirt with a variety of colors.
What are the causes of the fabric color difference and garment color difference?
The fabric color difference: one same roll fabric have left, center, right color difference(incluing dark or light edge), back-to-face shading; one same batch fabric have color difference between roll and roll, piece and peice, and out of color sample(including the sample color and product color difference, contracted sample and product color difference). The garment color difference: one same garment, different part have different color, the same part have color difference betwwen up, down, left and right; one set garment have color difference between piece and piece; one same shipment, different carton have color difference, different piece have color difference. The garment color difference is because of the fabric color difference, if the fabric has fewer color difference problem, garment is the same, otherwise, the garment have more problems. But some fabric color difference problems can be overcomed or lower the serious degree in the garment production process, some problems are difficult to overcome, the only way is not to use these fabric. So, the relation of the fabric color difference and garment color difference is not a simple causal relationship, but complex internal relations. By YULONG FR tex
What color is unbleached fabric?
Answer: Unbleached fabric has a light beige or natural off-white color.I think its is called Grey
What is the Japanese textile dyeing technique which uses wax to resist the dye?
I've not heard of using wax but there is a similar Japanese dyeing technique which uses resist paste made from rice flour and rice bran. This katazome stenciling technique is described below and is taken from the Japanese Textile History page found on www.kimonoboy.com Katazome is a Japanese originated method of dyeing textiles with a resist paste which is applied through a paper stencil (katagami). A sticky paste is made from rice flour and rice bran. This mixture is forced through a katagami (paper stencil) on to a piece of fabric, the stencil is removed and the paste on the fabric is allowed to dry. Next, the fabric is coated by brush with a sizing solution of soybean liquid. When the fabric is completely dry, the dyeing color is applied by brush. Then the sticky paste is washed away, and what remains is the stencil pattern in the fabric's original color and the surrounding area has absorbed color of the dye. Japan is credited with developing this dyeing technique to a level of unparalleled sophistication.
What is the meaning of dye?

How the Stain Appearance Happened in Textile Producing?
After textile fabric is woven, there will be several processes which may let fabric contact different kind of instruments, industry processing water and dyeing auxiliaries etc., that will make fabric staining which is a common problem in textile manufacturing. While the technology of fabric stain resistant become an important step that ensuring product quality, upgrading quality level and ensuring style of fabric. Fabric staining appearance usually occurred in these procedures: First, in storage. For example, dye house and laboratory are too close to storage grey fabric, half bleached fabric and finished products, and some kind of nature factors such as wind and rain or some kinds of human factors as staff contact, moving, these factors bring dyeing stuff and dyeing auxiliaries to storage which may cause staining. Second reason is staining in logistics. Such as irregular packaging while loading goods, then footprints stain the grey fabric or half-bleached surface, even through pre-treatment and washing, footprints are still leave on the fabric surface. Third is producing instruments staining. The ageing and rusting on the instrument, and lack of maintenance, or even repairing will leave dirt on fabric. Fourth is staining in dyeing process, while chemical reacting. The main appearance is while spot and color spot while washing print fabric, yarn-dyed striped cloth (eg. Yarn-dyed towel) staining while desizing, or poor color fastness of medium/deep color, and dyeing staining on different fiber while post-treatment of blended product. By YULONG FR tex
What is the introduction to Woven Fabric Dyeing Flaw?
1. Gasoline SpotAppearance: Tend to occur in E/R blend fabric, gasoline spot appear on the fabric after dyeing, and its color is darker than normal. Observed by a microscope, the top of dark spot lint is small bead shape, and the amount of lints is more than normal part.Reason: This is caused by singeing unevenness, lints of dark dyeing spot is not well singed, then they become melt bead on top, the bead got a strong dye absorption, so the color of this part is dark.2. Imperfect Penetration Of DyeAppearance: Dark and light cloud form on fabric surface after dyeing.Reason: 1). Inadequate desizing and refining, or wax and other materials stick to fabric after treatment.2). Low bath ratio in dyeing bath, heating rate is high, these factors make dye agent into retrogradation.3.Bleached HoleAppearance: Grey fabric is good, but after bleaching with hydrogen peroxide, warp yarns or weft yarns break on fabric then becoming a hole.Reason: There are rust stick on fabric surface, or there is iron ion in bleach water, iron ion Iron ions and hydrogen peroxide got sharp oxidation while bleaching lead to yarns breaking.4.SkilterinessAppearance: Irregular sheet color differences on fabric surface.Reason: Desizing and refining in pretreatment cannot be well-done.5. MistAppearance: Sheet dyeing spot which is dark or light, and without clear outline, shape, position and regulation.Reason: 1). Fabric is going to dye, is defiled by dirty water or other agent.2). After refined bleaching, fabric is placed in the cart without heating, then water spots were printed on fabric.3). Grey fabric got oil dirt, then heavy duty degreaser leave the spot on fabric while grey fabric inspection.By YULONG tex
How does a color of a fabric affect its temperature?
If the fabric color is dark then it absorb heat from the sun and the fabric's temperature will rise.

What are the weal spot in padding dyeing?
1.Article wrinkled: the reason is the fabric suffer the uneven tension and different press pass the nip, running roller crook or be out of shape, running roller or drying drum wear, dirty, the drying drum are not at a line, temperature is not suitable when dyeing. 2.Color difference between around and side: main reason is unevenness press at the nip, residual alkaline agent, surfactant, silicon salt in fabric, different damage degree roller, unsuitable roller, etc. 3.Dyeing spot: main reason is bad modulation of dye agent, not enough filtration, improper temperature, improper store or stir of dyeing agent, improper compose of dye bath. 4.Waterlogging: main reason is low temperature of the interlayer of the top steam box, cooling water existence at the feed in of the steam box, running roller stop work. 5.Washable: poor wear-resisting and lighting fastness, main reason is infixation dye agent deposit at the fabric. 6.Weak spot: reason is lint on the running roller 7.Color change: the reason is dye chromophore structures is changed by the environment, which is temperature, humidity, light and light source. 8.Color different of the fabric samples and bulk: reason is the difference of the dye agent, padding time, color fixing time and temperature. Different machine and balance precise, the difference pere treatment of greige, different water, etc. So the hand sample should be duplicated another sample and then confirm the production of the bulk.
