Description
Technical field
The invention belongs to garment production technical field, more particularly to a kind of colouring method of fruit button.
Background technology
Button is exactly to be used for the fastener that the both sides hem are connected on clothes, and its initial effect is for connection to the door of clothes
The flap, gradually developed into and artistry and dicoration had more in addition to its original function is kept, be also dress ornament it is personalized and
The representative of multifunction.
Button presses the classification of its material, can be divided into natural class, chemical and other materials, wherein natural class button master
To be shell button, fruit button, ox horn button, ox bone button etc..In the last few years, fruit button, also known as ivory nut, because it is special
The natural color and quality having, has obtained concern more in the industry.
Fruit button be TAGUA coco fruits gelatin it is ripe after, become like the white hard material of ivory.Its
Texture, hardness, color are similar to ivory, thus are referred to as in the industry " vegetable ivory " again.The COROZO NUT dried completely can
For substituting real ivory product, the Ecuador in South America is originated from its main blank more, using shell as base base, processed.
The manufacturing process of kernel button is different from the manufacture craft that conventional resins are buckled completely, is characterized in that quality is hard, texture is good, resistance to presses
Scald, rapid laser carving can be used, be the first choice of current domestic high-grade men's clothing, meet and wearing the clothes for natural green environmental protection is advocated now
Lead.
It is in the field of business, fruit button be often used as it is single buckle, it is radium-shine buckle, it is burning hot buckle, burn buckle, wire drawing is buckled, dye class button.
With requiring to improve constantly to the sample color of fruit button in field, the demand of the fruit button to dyeing class was increasingly carried in the last few years
It is high.And due to the natural characteristic of fruit button, have higher requirement to coloring in the fabrication process, at present, use in the industry
Fruit button is dyed with the mode of direct dyes or reactive dye color fixing at high temperature.It is generally divided into bleaching-cleaning-weigh
The step of dyestuff-dyeing-cleaning-fixation-cleaning-dehydration-drying, realizes the dyeing flow of whole fruit button.
But, in existing actual production when contaminating bright-colored to fruit button, due to the fruit knob of different batches
Detain raw material to differ to what Dye Adsorption was showed in dyeing course so that during bright color fruit button, often
There is aberration problem.
Therefore, with further requirement of the consumer to fruit button color, a kind of fruit of uniform in color how is obtained
Toggle, is always technical problem urgently to be resolved hurrily in the industry.
