Description

A kind of superfine fibre of the gray colored raw material that mixes and the fabric that superfine fibre constituted thus

Technical field

The invention provides a kind of have the doping gray colored raw material superfine fibre of neutral form and aspect and the fabric that superfine fibre constituted thus, especially this fabric of finger can chase after in the dyeing and finishing stage again and dye (additional dyeing process), and engrain becomes needed various different colours, and the fabric behind the engrain, except that having softness, careful sense of touch, and have splendid colour fastness to rubbing, anti-color of sunshine fastness and the water-fast COLOR FASTNESS of washing.

Background technology

Use the single fiber fineness to be lower than the fabric that 0.5 red Buddhist nun's ultra fine yarn is constituted,, be subjected to the market favorable comment after the release deeply, extensively be used in purposes such as dress material and family's decorations because of cloth cover has softness, careful sense of touch.But because of the fineness of fiber thinner, it is big that surface area becomes relatively, though when the addition of dyestuff to saturation state, fabric still can't be dyed dark color, though or dyed dark color, because of dyestuff can't the infiltrated fiber structure in, so having the not good problem of dyefastness takes place, for obtaining preferable fastness,, all can only be dyed more shallow color at present by the fabric that ultra fine yarn constituted.

Have problems such as fastness is not good are arranged after can't dying dark color or dying dark color for improving fabric that ultra fine yarn constitutes, and for meeting the demand in market, the fiber industry all actively drops into research, simultaneously, and have patent to be delivered out, for example, among the patent WO 02/088444 of Korea S KOLON company, a kind of fabric that ultra fine yarn constituted with doping colouring material composition (dope dyed component) is proposed, with washing fastness and the fastness to light of improving fabric; Patent WO 02/088444 utilizes carbon black (carbon black), pigment (pigment) and dyestuff raw material coloring components (dope dyed component) such as (dyestuff) is made up allotment, to reach desirable color, but when producing with this method, except that the painted toning of raw material and the work of checking colors are very difficult, when needs change colour, painted residual for guaranteeing not have other raw material in the pipeline, need with long-time eliminating waste water and detergent line, the very shortcoming of inconvenience is arranged in the production, and can't cater to the market requirement changeable fabric color.

Summary of the invention

For improving this shortcoming, the present invention uses the ultra fine yarn of doping gray colored raw material (gray dope dyedcomponent) to constitute a kind of fabric, and this kind fabric is in dyeing and finishing during the stage, can impose again to chase after and dye (additional dyeing process), make fabric under low dye strength, can be dyed various dark colors is color, this dark color is that water-fast COLOR FASTNESS, colour fastness to rubbing and the anti-color of sunshine fastness of washing of fabric is all good, and can reduce needs the long-time loss that effluent caused that removes when changing colour.

Therefore, main purpose of the present invention is that the ultra fine yarn of producing the doping gray colored raw material of the neutral form and aspect of a kind of tool reaches the fabric that ultra fine yarn constituted thus, the single fiber fineness scope of the ultra fine yarn of this doping gray colored raw material is 0.01 to 0.5 red Buddhist nun, the fabric that ultra fine yarn constituted of the gray colored of mixing thus raw material, in the dyeing and finishing stage, can be again to chase after the mode of dying, engrain becomes needed various different colours, fabric behind the engrain, except that having softness, careful sense of touch, and have splendid colour fastness to rubbing, anti-color of sunshine fastness and the water-fast COLOR FASTNESS of washing.

By grey in red, yellow, primary colors, all be not partial to wherein any form and aspect, belong to color than the neutral form and aspect of tool, use the ultra fine yarn of doping gray colored material composition (dope dyedcomponent), after constituting fabric, dye (additionaldyeing process) mode again to chase after, and engrain is when becoming needed shades of colour in the dyeing and finishing stage, because be not with other coloured light, check colors than being easier to.And constitute the raw material of this gray colored material composition (dope dyedcomponent), can be formed by pigment (pigment) and dyestuff (dyestuff), wherein, the gray colored raw material to be formed again by pigment (pigment), the fastness when being used in ultra fine yarn is preferable.

And the present invention is added into the interpolation percentage by weight in the condensate with gray colored material composition (dope dyed component), there is no particular restriction, but generally be advisable with 3 to 15wt% (percentage by weights), when addition is lower than 3wt%, because of being not easy to mix with condensate, be easier to produce aberration between ingot, and addition is when being higher than 15wt%, spinnability and fibrous physical property are easier to be affected and variation; In addition, the interpolation form and the mode of gray colored material composition (dope dyed component), also there is not particular restriction, generally be to make master batch (masterbatch) form, the spinning stage to fusion machine feeding before, the mode of using metering system (dosing unit) and condensate together to feed more often is used, among the present invention the condensate that uses based on polyester (polyester), can also add in this condensate such as additives such as titanium dioxide, antibiotic composition, uvioresistant composition or difficult combustion compositions, to obtain other functional character.

The ultra fine yarn of doping gray colored raw material shown in the present, single fiber fineness scope is 0.01 to 0.5 red Buddhist nun, when single fiber fineness during greater than 0.5 red Buddhist nun, when dying dark color in the ordinary stain mode, though can obtain splendid COLOR FASTNESS, and need not chase after again and dye (additional dyeing process) and improve COLOR FASTNESS, but because red Buddhist nun is thicker, the fabric that is constituted lacks soft and careful sense of touch with colouring material composition (dopedyed component); And the single fiber fineness is during less than 0.01 red Buddhist nun, though fabric has soft and careful sense of touch, and is meticulous because of fineness, need improve the addition of colouring material composition (dope dyed component) again, improving color depth and COLOR FASTNESS, but spinnability and fibrous physical property can't be accepted variation.

The superfine fibre of doping gray colored raw material shown in the present, it makes single fiber fineness scope 0.01 to 0.5 red Buddhist nun's the mode of production, do not limit especially, can make by polyester list composition direct fabrics (direct spinning), perhaps can and easily be carried out composite spinning (bi-component spinning) by polyester by the molten upgrading polyester that removes of alkali lye (alkali easy soluble copolymerised polyester), to make Splittable (split type) or fabric of island-in-sea type (sea islandtype) superfine fibre composite yarn, relend by the alkali lye decrement, with easily by the molten upgrading polyester that removes of alkali lye (alkali easy soluble copolymerised polyester) composition is molten remove after, and make hyperfine polyester fiber; When general single fiber fineness is lower than 0.25 red Buddhist nun, consider the spinning productivity, more often be used through the mode of alkali lye decrement again with composite spinning.

The kenel of the ultra fine yarn of doping gray colored raw material shown in the present does not limit especially, can be processing yarn (Draw Textured Yarn); Precursor (Full Draw Yarn); Air form volume yarn (AirTextured Yarn) or can be higher than 15% high-shrinkage yarn compound with boiling water shrinkage (Boiling Water Shrinkage%), produce the different shrinkage superfine processing yarn or the different shrinkage superfine precursor of tool doping gray colored raw material, this boiling water shrinkage (Boiling Water Shrinkage%) is higher than 15% high-shrinkage yarn; If it is then better to add doping gray colored material composition (dope dyed component).

The fabric that constitutes by the ultra fine yarn of using tool doping gray colored raw material shown in the present, chasing after the staining method that dyes (additional dyeing), there is no any particular restriction, the color of fabric and the depth, can be by the weight of adjusting the gray colored raw material or dye colour and concentration when adjusting dyeing reach, have the character shown in the following table 1.
