Description
Technical field
The present invention relates to a kind of black sea-island fibre, more particularly to a kind of original liquid coloring black sea of use fusion method production
Island fiber.
Background technology
Figured islands-in-sea superfine fibre Glove suede leather outward appearance has the magnificent, noble of natural suede leather, high resilience, the feel of wool
Rich real feature, and it is excellent in terms of uniformity, wrinkle resistance, sewing property, gas permeability, security, anti-mildew damaging by worms property
In natural leather, it is suitable for making clothes, playshoes, bag, high-grade leather, gloves, family property, automotive trim etc..
Black car interior trim super fiber leather because having the advantages that to bear dirty, will not reflective, pardon it is strong, designed by automobile vendor
The pro-gaze of department.But prepare the aterrimus and high automotive trim super fiber leather of fastness has technical difficulty and environment from the dyeing and finishing stage
Pollution problem：(1) sea-island fibre is difficult to obtain deep dyeing and weaving thing, particularly pitch black yarn dyed fabric.Because sea-island composite fiber line is close
Degree is low, and specific surface area is big, adds in irregular shape, and reflection and scattering to light are strengthened, and the colour developing efficiency of dyestuff is low, i.e. colour rendering
Difference.In order to obtain same color depth, Dyeing of Superfine Polyester Fibre amount of dye will often be several times as much as general fibre, even if so also not
One surely obtains deep dye product.(2) dyefastness is poor.Superfine fibre surface area is big, and surface is not smooth enough, the dyestuff of contamination it is many and
It is difficult to wash to the greatest extent, therefore the wet fastness of dyeing of Superfine Fibre Fabric is lower than conventional fibre.The amorphous region content of this outer fiber is high, by
After heat, dyestuff is easily diffused into surface from fibrous inside, causes crock fastness to reduce.Fiber surface area causes the distillation of dyestuff again greatly
Chance increases, thus fastness to sublimation significantly declines.In addition, traditional dyeing and finishing technology need to consume the substantial amounts of energy, water and
Industrial chemicals, industrial wastewater complicated component, colourity are deep, basicity is high, organic pollution content is big, as in superfine fibre industrial chain
Pollute one of link the most serious.
Also it is difficult to obtain aterrimus and the high figured islands-in-sea superfine fibre of fastness using color method before conventional spin.Pass through
It is known technology that the original liquid coloring technologies such as addition pigment, Masterbatch, which prepare color silk, disclosure satisfy that demand of the product to color,
Product color fastness is high, will not produce the dyeing specks such as aberration, color spot, dyeing defect.But, for the composite spinning of island, because
The diameter of island component is small, the superfine fibre for being difficult to obtain black using conventional method, and under spinning properties variation, fiber quality
Drop：
(1) using the adding proportion of conventional black Masterbatch, grey is presented in the sea-island fibre being made, and blackness is far from enough；
(2) Masterbatch adding proportion is increased, then fluidity of molten is deteriorated, head, breakage phenomena increase, fiber physical property decline.
In view of not yet having the aterrimus sea-island fibre of good color fastness in the market, in order to meet in the market to aterrimus sea
The demand of island ultrafine fiber, the present invention provides a kind of black sea-island fibre of original liquid coloring.
The content of the invention
It is of the invention by high polymer material component for not yet there is a kind of black sea-island fibre of good color fastness in the prior art
Granulated with after carbon black, CNT mixing, by melt spinning, obtain the good black two-component sea-island fibre of the firm color of color.
Original liquid coloring black sea-island fibre in the present invention, island component includes the black that percentage by weight is 1%~60%
Masterbatch and 10%~90% polyamide 6 or polyester, sea component is alkali soluble polyester；Sea component and island component are multiple by melting
Close spinning and sea-island fibre is made；After obtained sea-island fibre is handled through fibrillation, fiber number ＜ 0.08dtex, blackness L values ＜ 15, color jail
Degree is not less than 4 grades.
Original liquid coloring black sea-island fibre in the present invention, it is (10~12) to include parts by weight in black Masterbatch:
(8~10): 80 carbon black, CNT and matrix polymer；Carbon black carries out table using matrix polymer macromolecular graft reaction
Face is modified；CNT carries out surface modification using matrix polymer macromolecular graft reaction；Matrix polymer from polyester and
One kind in polyamide 6.
The weight ratio of original liquid coloring black sea-island fibre in the present invention, sea component and island component is (10~50): (50~
90)。
Original liquid coloring black sea-island fibre in the present invention, the fiber number of sea-island fibre is 2.5~3.5dtex, fracture strength
It is not less than 2.5cN/dtex.
Beneficial effect：Raw material is uniformly dispersed in the original liquid coloring black sea-island fibre production process that the present invention is provided, fibrillation
Island fiber afterwards is aterrimus, and fiber number ＜ 0.08dtex, blackness value is not higher than 15, and uniform in color, color fastness is high, light fastness and
Dry fastness is not less than 4 grades.
