Description
Technical field
The present invention relates to a kind of fine-denier polyamide fiber elastic filament and preparation method thereof, particularly a kind of color mixed fibre fine denier chinlon stretch yarn and manufacture method thereof that is used for dress ornament.
Background technology
About the definition of thin dawn, micro Denier, superfine Denier fibre, still there is not unified standard in the world.China is filament number that the fiber of 0.9～1.4dtex becomes fine denier filament generally; 0.55～1.1dtex is the micro Denier silk; And the following fiber of 0.55dtex is a superfine denier fiber.Fine denier filament of the present invention is the POLYAMIDE YARNS of filament diameter between 0.9～1.4dtex.Because the filament number of thin specialization fibre is thin, bending rigidity is little, thereby the apparent thin clean exquisiteness of its fabric, soft exquisiteness and drapability are fabulous.
Human haberdashery comprises clothes and ornament two large divisions, and is varied, a feast for the eyes at aspects such as color and luster, style, materials.Wherein on the material, the synthetic chemistry fiber has occupied deal greatly.Exploratory development, processed through people, with the chemical fibre is the haberdashery of raw material, not only reached the style and features that natural fabric had, but also possessed the not available function of natural fabric, as moisture absorbing and sweat releasing, the warming safety etc. of breathing freely, keep healthy.Its noble quality beautiful in colour, comfortable and easy to wear, attractive in appearance becomes indispensable a beautiful landscape in people's life.
But above-mentioned chemical fibre can produce a large amount of pollutions in the process of making dyeing, and the filametntary elasticity of gained and permeability all are not very desirable, and its color and luster is also more single, and feel is relatively poor.The at present domestic fine count fiber that occurred in a large number is as the raw material of making clothes, and it is representing the developing direction of following dress ornament industry.But the feature of environmental protection of its color and luster, elasticity, anti-microbial property, gas permeability and manufacture craft does not all reach desirable effect.
Summary of the invention
The invention solves existing in prior technology the problems referred to above, a kind of diverse in function, color and luster uniqueness are provided, the other tool of style, good hand feeling softness, air permeable effect is good, and the color mixed fibre fine denier chinlon stretch yarn and the manufacture method thereof that are used for the dress ornament making of environmental protection and energy saving.
Above-mentioned technical purpose of the present invention solves by the following technical programs:
A kind of color mixed fibre fine denier chinlon stretch yarn is characterized in that it is that the fine-denier polyamide fiber of the different colours made by participating in the different colours master batch respectively is entwined, and the cross section of described fine-denier polyamide fiber is at least two kinds of shapes.Two or more fine-denier polyamide fiber mixed with fibers that described mixed fibre is different color, different cross section, iso-fineness, exclusive-OR function adds bullet and is entwined.Usually the cross section of the fiber in chemical fibre field is round, and the fabric air-permeability performance is relatively poor.The manufacturing route of chemical fibre haberdashery is generally: industrial chemicals is spun into white fiber, then fiber weaving is become grey cloth, the stock-dye of white can be made haberdashery; Perhaps industrial chemicals is spun into white fiber and dyes then, be woven into grey cloth again, make haberdashery at last.Its process route is longer, and energy consumption is big, the production cost height, and wherein dyeing process certainly leads to a large amount of contaminant water simultaneously, is unfavorable for environmental protection and energy-conservation.Characteristics such as the present invention at first joins coloured master batch in the raw material of polyamide fibre, and the adding of color grain has saved the step of dyeing, and it has bright in luster, is difficult for fading, and energy consumption is low.The adding method of the master batch of different colours of the present invention promptly is that the master batch with a kind of color joins the POLYAMIDE YARNS that makes this color in the raw material, the master batch of another kind of color is joined the POLYAMIDE YARNS that makes another kind of color in the raw material in addition, the POLYAMIDE YARNS of two kinds of colors is entwined is color mixed fibre fine denier chinlon stretch yarn of the present invention again.The shape of described POLYAMIDE YARNS different cross section can be triangle, three leaves, T type, polygonal, polygonal such as five-pointed star, five leaves, hexagonal, a type; Also flat belt-like such as dog bone shape, beans shape and hollow shape as circle hollow, triangle hollow, plum blossom hollow etc.The meaning that the cross section of fine-denier polyamide fiber of the present invention is at least two kinds of shapes is can the same color different cross section, also different colours same cross-sectional or different colours different cross section, the cross section of require twining the used polyamide fibre of the elastic filament that obtains in a word is two or more, simultaneously a part of polyamide fibre can not added color grain yet, white and coloured POLYAMIDE YARNS are twined.The elastic filament that uses the polyamide fibre in multiple cross section of the present invention to obtain has the good optical performance.Fiber does not have the light of dazzling the eyes as the metal, and has the gloss as soft, plain, the real silk.Surface area because of strand increases simultaneously, thus the corresponding covering power that increases fiber, and the transparency is reduced.Owing to the special shape in cross section, increased the stiffness of interfibrous cohesive force, bulkiness, gas permeability and strand, reduced the wax shape sense of synthetic fiber, make its feel more comfortable, wearability is better.
Process route of the present invention is the painted mode of master batch that adopts in the process of spinning fibre, solves an environmental protection difficult problem in the production, directly produces colored fibre, weaves and be cut into haberdashery then.Omitted traditional dyeing process, environmental protection and energy saving.
The dress ornament that different colours makes the elastic filament of gained of the present invention make noble quality beautiful in colour, attractive in appearance.As preferably, the fine-denier polyamide fiber of described different colours is the fine-denier polyamide fiber of two kinds of colors, and the cross section of described fine-denier polyamide fiber is three kinds of shapes in circular cross-section, hollow type cross section, the triangular form cross section.Elastic filament adopts the POLYAMIDE YARNS of three kinds of different cross sections to be entwined, and its permeability and thermal property are all comparatively outstanding, and the relatively large perspire effect of its surface area is better simultaneously.
A kind of preparation method of color mixed fibre fine denier chinlon stretch yarn is characterized in that it may further comprise the steps:
A: in materials of the synthetic fibre, add the color grain of raw material weight 2～10%, raw material is made into coloured preorientation drafted fibre;
