It is widely used in clothing and home decoration. However, due to the fineness of the fiber, the surface area is relatively large. When the amount of dye added is saturated, the fabric cannot be dyed dark, or it has been dyed dark, but (4) the material cannot penetrate the fiber. In the structure, there is a problem that the dyeing fastness is not good. In order to obtain better fastness, the fabric composed of the superfine yarn can only be dyed into a lighter color. In order to improve the fabric composed of superfine yarns, there are problems such as the inability to rotate the dark color or the poorness of the _ color, and in order to meet the needs of the market, the fiber transfer industry is not actively investing in research, and at the same time, patents have been published. For example, the WO _88444 patent needle of KOLON Corporation of Korea proposes a fabric composed of superfine yarns having the original composition (dGpedyede (4) m) to change the washing fastness and light fastness of the fabric; w〇_88444 Supplement (4) · Combine the carbon black (caJn black), pigment (pigment) and dye (dyes_ and other original components (d〇pedyed_p_t), and spur the hope _ color, but the money is raw, and (10) Color and h is very difficult. When it is necessary to change the color, in order to ensure that there are no other original components in the pipeline, the 'long-cleaning pipeline' is extremely inconvenient to produce, and it cannot meet the market's variable color. In order to improve this disadvantage, the present invention uses an ultrafine yarn containing a gray original component ((4)-a letter P〇nent) to form a fabric, and such a fabric can be further used in the dyeing and finishing stage. Tracing (addltl〇nal dyemgproc Ess), so that the fabric can be dyed into various dark colors under the dye concentration. 'This dark fabric has good wash fastness, good color fastness and fast color fastness. The loss caused by the long-time cleaning of the pipeline during color change can be reduced. Therefore, the main object of the present invention is to produce a gray original superfine yarn having a neutral hue and a fabric composed of the superfine yarn, the gray The fineness of the single fiber of the superfine yarn ranges from _ to 0.5 denier, and the fabric composed of the gray superfine yarn can be dyed and dyed in the dyeing and finishing stage to deeply dye the various defects of the S. Color, deep fabric, in addition to soft, delicate touch, and has excellent resistance to rubbing fastness, daylight fastness and wash fastness. In the primary colors, none of them are biased toward any of the hue, and the color is more in the middle I* hue, so as to contain the ultrafine V of the d原pe dye (JC〇mp〇nent), after forming the fabric, In the dyeing and finishing stage, the additional dyeing process is used to deeply dye the various types needed. In color, because there is no other color light, it is easier to color. The raw material that constitutes the dope dyed component can be composed of pigments and dyestuffs, among which pigments & The gray original component material composed of the igment is preferably used in the superfine yarn. The weight percentage of the addition of the dope dyed component to the polymer in the present invention is not particularly limited, but Generally, it is preferably 3 to 15 wt% (by weight). When the amount is less than 3 wt〇/〇, it is not easy to mix uniformly with the polymer, and it is easy to produce chromatic aberration between ingots, and the addition amount is higher than 15 wt%. When spinning and fiber properties are more susceptible to deterioration, the form and manner of addition of the dope dyed component are not particularly limited. Generally, it is made into a masterbatch form. Before the wire stage is fed to the melting machine, the dosing unit is used together with the polymer to feed it. In the present invention, the 1282823 polymer is mainly composed of polyester. Body may also add an additive such as titanium dioxide, anti-bacterial ingredients, UV or flame-retardant composition components and the like, to obtain other performance characteristics. The gray original superfine yarn shown in the present invention has a single fiber fineness range of read to 〇·5 denierny, and when the single fiber fineness is more than 0.5 denier, when dyed into a dark color by general dyeing, Although it is possible to know the excellent color cow's and does not need to use the original dyeing process (d〇pe dyed c〇mp〇nent) to improve the color fastness, but because Danny is thicker, The fabric is less soft and delicate. When the single fiber is less than 〇〇1 Danny, the fabric has a soft and delicate thief. However, due to the fineness, the silk component needs to be increased (dGpedyedeGmp〇nent). The amount of addition, which reduces the color depth and color fastness, but the touch, sex and fidelity will be deteriorated and cannot be accepted. The gray original microfiber shown in the present invention is produced by a single fiber fineness range of 〇〇1 to 〇5 Danny, and is not limited to, and can be directly spun into the scented spinnmg). Alternatively, the polyester may be bi-c〇mp〇nent spiming with a modified polyester (alkali (10) s〇hble copolymerised polyester) which is easily dissolved by the alkali solution to prepare a split type. Or island-type (sea isiand twisted microfiber composite yarn, and then by the reduction of alkali liquor, the easy-to-test liquid> the easy-to-test polyester (alkali easy soluble copolymerised polyester) bath after the addition Fine polyester fiber; generally, the fineness of a single fiber is lower than that of 〇·25 Danny, considering the spinning productivity, it is often used in the form of composite spinning and reduction by alkali liquor. The type of the spun yarn is not particularly limited, and may be Draw Textured Yam; Full Draw Yam; Air Textured Yam or Boiling Water Shrinkage%. High shrinkage yarn composite of more than 15%, producing different shrinkage gray tone original ultra-fine processing Yarn or different shrinkage gray tone original ultrafine raw silk, this boiling water shrinkage rate (Boiling Water Shrinkage%) is higher than 15% of the high shrinkage yarn; if the addition of the gray original component (dope dyed component) is better. The gray original superfine yarn shown is a fabric made of knitting or weaving 1282823 square. There is no special restriction on the dyeing method of additional dyeing. The color and depth of the fabric can be borrowed. It is achieved by adjusting the depth of the gray original superfine yarn or adjusting the dye color and concentration during dyeing, but has the properties shown in the following table.
