1.Summarize

With the development of science and technology, the product of leatheroid is more and more well. Thought its capability is not as well with the natural leatheroid, but its price is cheaper than the leather and it has a wide variety of handle. In addition it also can mass production, so that it playing an ever more significant role in people’s daily life. From clothes、box、shoes to furniture as well as upholstery. The leatheroid almost can replace the leather in any place that can use leather. In recent years, the pearl leather made from the pearl pigment is much adapted to clothes, sofa and so on, become a terrific splash products in the leatheriod.

2. Application in leatheroid

The pearl pigment has obvious pearl luster effect, and it is non-toxic, tasteless, high temperature resist, non-acid, non- alkali, stable chemical properties. It can be widely used in the printing of natural leather and manufacturing of man-made leather. Generally speaking, we can put pearl pigment into plastic ink; it is used in the printing of man-made and surface painting. We also can put pearl pigment into transparent plastic resin used in the pressing and scratching of pearl leather.

3. Requisition for carrier and consumption of pearl pigment

Because the pearl pigment rely on the reflection of light to produce pearly-luster, so it require the resin, pigment and other filling used cooperate with it have higher transparency. Both the pigment and additive which are opaque or high hiding power, such as titanium white powder, etc can weaken the pearly-luster result. So they must avoid using with the pearl pigment. But can join proper weight as one feels fit in specific cases, in order to increase the strength of hiding of the pearly-luster membrane. The pearly-luster pigment is used in the form stamp-pad ink black; its density is about 15% of the total amount of printing ink. Mix resin prescription produce pearly-luster change, its density is about 2% directly --5%, if being transparency low; system should increase consumption, pearly-luster of pigment or adopt particle heavy pearly-luster pigment in right amount.

4. The usual pearl pigment application in leatheroid

Silver white：100、120、121、118、122、110、111 and so on.

Interference: 205、215、219、225、235 and so on.

Iron metal series: 500、502、504、505、506、508、522、524 and so on.

Golden: 300、302、303、323 and so on.

5.The Specification and packing of the pearl pigment

The size, extent of the granule is 5--700μ, the customer can choose different types according his needs.

The standard packing is 25kg, the small samples and color cards are offered free, welcome to ask for.

6. The usual problem and methods

A. if the pearly luster is not effect

◆You may have added the strong hiding power of pigment and filling.

◆The dosage of the pearl pigment is overabundance or too little.

◆Check the network line and carve depth of the printing cylinder is weather match with the particle size of the pearl pigment. There are products materials in our company, suitable for asking for and reading.

◆ The Printing ink transparency is weak or the membrane is not very well, and the surface luster is not enough. We advise you use better printing ink instead.

◆ you should check the pearl pigment weather separate enough, the group gathered pearl pigment will influences the pearly-luster result.

B. the surface of the leatheroid appear needle hole or little bubble.
