Abstract
The invention relates to a superfine fiber filament. A single fiber 1F comprises 20-30 colored filament-shaped components A ( the fineness of a single filament is about 0.2 d tex) and components B which surround and fill the peripheries and gaps of the components A; the mass percentage content of the components A ranges from 75% to 95%; the mass percentage content of the components B ranges from 5% to 25%; the crystallinity of the components A ranges from 60% to 90%; the crystallinity of the components B ranges from 5% to 40%. The superfine fiber filament provided by the invention has the following benefits: dye is not required, so that dyeing wastewater is not generated and the environment is not subject to the dyeing pollution; the quality of the chamois leather fabric is greatly improved.
Description
(1) technical field
The present invention relates to a kind of superfine fibre long filament, and utilize this superfine fibre long filament to make without the method for dying chamois leather fabric.
(2) background technology
In the present people's of chamois flannel face fabric life application more and more extensive, be mainly used in clothes, sofa, shoes and hats, case and bag field.Suede nap mainly adopts island superfine fiber manufacture, fabric by preshrunk, alkali decrement, open the operation such as fibre, pre-setting, plucking sanding, dyeing and produce chamois flannel face fabric.
General superfine fibre long filament skin sense pile fabric major part need to be carried out synthetic fiber spinning and rear arrangement dyeing processing.For example Chinese patent No. 83109961, No. 76102732, No. 79108906, No. 8110032, No. 200410000690.7, is to drive fine and machinery by chemical fibre to open after fibre, and the super long and slender dimension of fabric is dyeed.What adopt due to chamois flannel face fabric is the fiber manufacture such as terylene islands-in-sea type fibre, polyester-nylon superthin fiber, and after opening fibre, the fiber number of fiber reaches about 0.2dtex.The specific area of fiber reaches tens times of conventional fibre, and therefore the surperficial adsorption capacity of fiber is strengthened greatly when disperse dyeing.Some dyestuffs are combined dyeing with fiber, and 1/4～1/3 Dye Adsorption is on the surface of fiber, often when fabric cleans, enters sewage, increases COD discharge, causes environmental pollution.
(3) summary of the invention
The object of the invention is to provide and a kind ofly can produce dyeing waste without the colour superfine fiber filament of dyeing with without the manufacture method of dying chamois leather fabric, can not cause dyeing to pollute to environment, makes environment obtain good protection.
The technical solution used in the present invention is:
A kind of superfine fibre long filament, the B component that single fiber 1F surrounds and fills by 20～30 coloured filament shape component A with in component A periphery and space forms; Described component A quality percentage composition is 75%～95%, B component quality percentage composition is 5%～25%; Described component A degree of crystallinity is 60%～90%, and B component degree of crystallinity is 5%～40%; Described component A is the high molecular polymer A (requiring to mix certain proportion carbon dust at component A according to color depth) that is mixed with color grain, described high molecular polymer A is one of following: poly terephthalic acid second two fat, poly terephthalic acid the third two fat, poly terephthalic acid fourth two fat, polyolefin elastomer, polyurethane, polyurethane elastomer, polyvinyl alcohol, nylon 6, nylon 66, nylon 11, nylon 12, be preferably poly terephthalic acid second two fat; Described B component is the polymer of monomer one and monomer two, described monomer one is one of following: adipic acid, azelaic acid, terephthalic acid (TPA), M-phthalic acid, cyclohexane-1,4 dihydroxy acids, 1,6 hexamethylene diamines, trimethyl-1,6 hexamethylene diamines, 4,4 '-diaminourea-dicyclohexyl propane, different fluorine that ketone diamines, caprolactam, 4,4 '-diphenylmethane diisocyanate fat; Described monomer two is one of following: formic acid, to alkyl benzoic acid, isophthalic first diacid, ethylene glycol, methyl alcohol, second diester, B component is preferably the polymer of terephthalic acid (TPA) and second two fat.The volume of described carbon dust requires different according to color depth, the percentage by weight that generally accounts for high molecular polymer A is 0.1～15%.
Described superfine fibre filament fiber single fiber cross section is coloured component A (can be the shape such as circle or pentalpha ★, trilobal Y), and white component B is the parcel binding material (referring to Fig. 1) of component A.This fiber is made after base cloth, pass through shrink process, fiber clashes into through air-flow and the rubbing of water-bath stream, decrement is opened fibre, dissolve and remove B component, the structure of fiber is formed with the fluffy tow that colour cell is divided A, and individual filament fineness dpf is 0.2dtex left and right, and around this principle the coloured nothing of invention colour superfine fiber, base cloth and making is dyed chamois leather.
Concrete, described superfine fibre long filament is made up with composite spinning method under 150 DEG C～300 DEG C of spinning temperatures, draw off rate 3000～4000m/min condition of component A and B component.
The invention still further relates to a kind of method of utilizing described superfine fibre long filament making nothing to dye chamois leather fabric, described method comprises:
(1) grey cloth is made: make double knit garden machine cloth with described superfine fibre long filament, grammes per square metre is 120～200 grams/every square metre;
(2) make without dying chamois leather fabric: by the first 85 DEG C of preshrunks of step (1) grey cloth, then after 95 DEG C of hot water treatment 40min, at 80 DEG C, open fine 40min, opening fine agents useful for same is that phenmethylol 2%～6% is (to grey cloth weight ratio, lower with), butyl glycidyl ether 1%, NaOH2%～4%, grey cloth is 1:10～15 with the ratio of water weight; Through pre-setting, plucking, sanding, 135 DEG C of high-temperature shrinkage, 180 DEG C of sizings, obtain described nothing and dye chamois leather fabric finished product again.
Tradition chamois leather fabric is made flow process: grey cloth---8 DEG C of preshrunks---95 DEG C of alkali decrements,---170 DEG C of pre-settings---plucking---sanding---130 DEG C of dyeing---180 DEG C of sizings---inspection---finished product of opening fibre, the dyestuff of not painting enters in waste water, draining colourity is dark, produces the degree of depth and pollutes.The present invention is without dyeing, and draining is colourless, has effectively protected environment.
The chamois leather fabric making according to the inventive method, through dyeing, superfine fibre filament surface can absorbing dye, can not produce the phenomenon that fades, dyefastness significantly improves: from original 2.5 grades bring up to 3.0 grades and more than.Leading indicator is as follows: colorfastness to rubbing: dry grind 3.0 grades and above, 3.0 grades of wet-millings and more than; Washing: 3.0 grades of water loggings and above, 3.0 grades of staining and more than; WASHING COLOR FASTNESS: 3.0 grades of water loggings and above, 3.0 grades of staining and more than, improved and improved people's clothing level and quality of life.
Beneficial effect of the present invention is mainly reflected in: adopt superfine fibre long filament of the present invention manufacture without dying chamois leather fabric, without dyeing, can not produce dyeing waste, can not cause dyeing to pollute to environment, and finished product chamois leather fabric quality greatly improves.
