Description
Technical field
The present invention relates to digit printing field, particularly, the present invention relates to a kind of wool fabric digit printing technique.
Background technology
Wool fibre is a kind of natural fabric, has many excellent performances liking deeply by consumers in general.Along with the sustainable development of China's economy, China has become wool spinning big producing country maximum in the world.Meanwhile, China is also the consumption big country of wool product.
But at home on market, except some stamp sweaters, we seldom see other stamp wool spinning products.The reason producing this situation has 2 points: one, batch is little, and current state-of-the-art screen printing machine is difficult to be adapted to the clothing fabric as top grade, needs the woolen stamp processing that embodiment fashion, personalized batch are less.Through design, retouch the operation such as original text, system net, not only the process-cycle is long, and cost is very high, and general stamp enterprise does not possess the condition of woolen Final finishing processing yet.Which limits the production of stamp wool fabric; Two, fabric is expensive, and wool fabric is much more expensive than other fabrics.In screen printing processing, reach the perfect register of polychrome style, may cause tens meters of fabric wastes, this also makes the output of stamp wool fabric be difficult to improve.So this is just applied to wool fabric with good opportunity to digit printing, the appearance of digit printing simultaneously has also broken how-do-you-do for woolen stamp.Digit printing does not need net processed compared with traditional dyeing and finishing technique, it produces the production process really achieving small lot, fast response, required high-precision Printing can be obtained on various weaving face fabric, and be not subject to the restriction of flower pattern size and color, for the stamp of wool fabric provides development platform.
At present, wool fabric digit printing is really wanted as its COTTON FABRIC digit printing, to realize the marketization, industrialization, still there is a lot of problem.Be in particular in that the traditional chlorination process of wool can bring AOX problem, make it apply and had a strong impact on.And chlorination itself also exist operation wayward, easily cause fabric yellowing and process the problems such as irregular.And if without chlorination process, the class lipid layer that wool fibre is hydrophobic and highly cross-linked exocuticle block dye molecule by scale layer and spread to fibrous inside, make PRINTED FABRIC Dry Sack very shallow, and irregular.
