Color mixing spinning
The process of spinning specifically is a kind of process of spinning coloured yarn in the present invention relates to weave.
The background technology spinning is divided into pure spinning, the fibrous raw material spinning of single variety.As cotton textiles spin, pure wool spins.Blending is that many kinds mixed with fibers is spinned together.Washing really very as cotton, is pure spin or blending all can not be only with they primary colors separately, needs the textiles of various colors in the life.Like this, dyeing will be arranged.Present technology has the color that yarn-dyed one-tenth is needed, and is made into textiles again.Having plenty of the cloth of being made into dyes again.Also have is to make clothes to dye again.In process of production, the temperature in the staining trough, the concentration of pigment all are can be along with by the yarn that dyed or irregular variation takes place in the immersion of cloth, and it is inconsistent that this will form the colourity of dying product priority.If what dye is yarn, piebald just appears in the cloth that this yarn weaves, if what dye is cloth, a cloth will appear and before and after look different.The blending fabric is more complicated when dyeing, adopt two bath methods, because it is different with the pigment that dyes chemical fibre to dye the pigment of cotton yarn, fabric must be dyed once in dying the staining bath of cotton yarn earlier, this fabric is dyed once in dying the staining bath of chemical fibre again.Use twice dyeing and finishing, the possibility that difference appears in color is bigger.On February 15th, 1994, publication number was the Japanese patent of invention of " 6-41837, the manufacture method of variable color yarn ".The scope of its application is, fiber unit put together elongate to form sliver, sliver is caught suitable color by fixing interval, the heterochromatic interregional boundary part adjacent with this sliver coloured portions, dye the state that tilts with the sliver length direction, Ran Se sliver is made yarn after weaving like this, introduces as the manufacture method of the variable color yarn of feature.This method remains fiber is elongated to sliver, and segmental dyeing on sliver is still in this category of dyeing yarn.The sliver diameter is thick more, and sliver surface and painted depth difference inside are just big more.Color and luster uneven performance in drafting spinning back is more obvious.Thereby the dyeing complexity of textiles, be difficult for grasping, cause the rate for fitting sample of product and yield rate low, can not satisfy customer requirements, the claim phenomenon that occurs returning goods is commonplace, causes enormous economic loss.
The objective of the invention is under the prerequisite of existing textile technology, to start with from the standardization of dyeing pigment and the uniformity of dyed yarn color.Its thinking is not a yarn, but sets about from the raw fiber dyeing of spinning.Before spinning, color is mixed well, thereby be called color mixing spinning.Utilize the method for color mixing spinning, reach the pure standard of color of the dyed yarn that spins, color and luster is even, rate for fitting sample and yield rate height, and technology is simple.
Realization of the present invention is the inspiration that is subjected to Chinese Academy of Sciences's Chinese colour system, finishes in conjunction with existing textile technology.
Chinese colour system is unit achievements in research such as Institute of Developed Organisms, Academia Sinica, Zhejiang University.Be divided into and do not have color system and color system is arranged.Do not have color system and be divided into white, grey, black three looks; The dividend of color system, yellow, green, blue, the purple five colors are arranged.Green in fact, purple is derived from by red, yellow, Lan Sanse.Grey has not been divided nine lightness grades between the pure white and black in having color system, just 90% white adds that 10% black is a lightness grade, another lightness grade is that 80% white adds 20% black ... by that analogy, last lightness grade is that 10% white adds 90% black.Like this, white, ash, black three chroma colors are standard very just, and draws easily.
By coloured silk be five kinds of looks then regulation form a colour circle.In the middle of per two kinds of looks, all derive a Neutral colour.For example: red 50% with blue look 50%, just derive the Neutral colour of a red orchid.Owing to be an annulus, 10 kinds of colors have just been formed.By this derivation, derive Neutral colour again between the per two adjacent colors, this colour circle regulation is 40 kinds, this is called tone.Also as there not being color system, every kind of tone is divided into nine lightness grades.360 kinds of different colors will appear in colour circle like this.These colors add the look that does not have color system, and shades of colour has different concentration, marks off chroma again.Announce altogether in the Chinese colour system sample volume like this and formed 1338 tinctorial patterns.This sample volume is the national material standard of State Bureau of Technical Supervision's approval, and standard No. is " A26003-94 ".
The present invention has only selected white, the black dichromatism that does not have in the color system for use when selecting color for use, red, yellow, the blue three kinds of looks in the color system are arranged.That color mixing spinning of the present invention so only needs is red, yellow, blue, black four kinds of dyestuffs, can be described as Essential colour.Add the white of fibrous raw material.The kind of color is few like this, the color specification that accesses by this principle.With Essential colour fibrous raw material is dyeed, all can as cotton or various chemical fibre.Comb pulls into sliver of all kinds in carding machine respectively, according to Chinese colour system sample volume specified hue lightness grade, Essential colour proportional numbers with required color, be transformed into the silver number of the Essential colour of this correspondence, these Essential colour slivers enter draft of drawing frame simultaneously and become mixed sliver yarn, or raw fiber is dyeed with Essential colour, in the ratio of Chinese colour system sample volume specified hue lightness grade with the required color Essential colour, be transformed into the weight ratio of this corresponding base true qualities raw fiber, drawing spinning, spun yarn through the carding machine comb is exactly required specified color.The phenomenon of irregular colour also can appear in the dyeing of raw material, but in carding machine through after tens mixing up to a hundred time, the aberration in the raw material will disappear, and makes color very even.On carding machine, feed quantity and speed and sliver are pulled out speed by outlet and all can effectively be controlled by machine, thereby can guarantee the sliver diameter of each Essential colour, the tightness unanimity, the length that is to say the sliver Unit Weight is consistent, and spun yarn color is even certainly through drawing frame and after closing for sliver.
For example, four on colour prime white sliver and six black slivers with same feeding speed and feed quantity are pulled out through carding machine are pulled into the mixing sliver through drawing frame, and spinning yarn is exactly not have the grey of six grades of lightness in the color system.If with two white slivers, eight black slivers, be exactly the grey of eight grades of lightness, darker than the grey of a last lightness, one of the darkest grey is white, and nine black, besides the fabric of ater.
Again for example in color system is arranged, red and yellow Neutral colour, the sliver of two kinds of looks respectively accounts for half, Neutral colour with red or yellow in the middle of be divided into four kinds of Neutral colour again separately.These ratios can be converted out by redness or yellow by calculating.Respectively be divided into nine lightness grades again between these eight Neutral colour, also the same with the classification in the color system of nothing, fixing ratio is arranged, can be converted into the ratio that red and yellow dichromatism respectively accounts for equally.Spin through drawing frame and after closing with corresponding redness and yellow sliver, just can obtain the fabric of required color.In case when the proportional numbers that occurs is non-integer, can adopt repeatedly the way of drafting to reach required ratio.
So no matter to be pure spinning or blending, can to adopt this process, comprise a painting cloth or plaids so long as the look of the textiles of staple fibre spins all.The assurance dyeing is simple, the pure standard of color, and color and luster is even, and rate for fitting sample can reach absolutely.
