Description
Technical field
The present invention relates to that a kind of fine denier modal pure fibers is spun or with the blended color spinning yarn and the production method thereof of other fiber blend, belong to the spinning engineering technical field in the caused by spinning industrial production.
Background technology
Fine denier modal fiber and common model all are the tModified Cellulose Fibers of a kind of high wet modulus of producing of Austrian Lenzin company, and its fibre fineness is 0.9D, and length is 38mm.This products material all is natural material, and is harmless, and can natural decomposition, and environmental sound belongs to the green ecological Recycled Fibers.The fine denier modal fiber is more very thin and soft than common Modal fibre, so have the better uniformity, high gloss, more a softer and smoother touch characteristic, good hand feeling and drapability; Its silk quality sense is stronger, wears more comfortable.The fine denier modal fiber yarn can be woven into high-grade linings such as emulation silk, peach face, suede nap, polar fleece, is the first-selection of weaving more high-grade knitting, woven fabric, and the product application prospect is boundless.Its product suit producing high-grade underwear, Ms's overcoat, high-grade leisure clothes, sportswear and household textiles can satisfy the pursuit of environmental protectionization, comfortableization, leisureization, and bright development prospect is arranged.But because the fine denier modal fibre number is very thin, has only 0.9 DENIER, the brute force of fiber itself is very little, utilize traditional dyeing and finishing processing method that fiber is sustained damage, very thin during dyeing because of fiber number, thereby not high for common dyestuff tinctorial yield, and dyefastness is not fine, therefore, the yarn color structure of producing with conventional method is single, can not adapt to the needs of consumer personalityization.
Summary of the invention
One of purpose of the present invention provide that a kind of fine denier modal pure fibers is spun or with the blended color spinning yarn of other fiber blend.
Another object of the present invention provides the production method of above-mentioned this blended color spinning yarn.
Fine-denier Modal fiber blended color yarn of the present invention, it is that fiber by two or more different colours forms by blended colour yarn, the fine denier modal fiber content is 40%～100% in the blended yarn.
Described fine denier modal fiber blended color spinning, spinning count is single thread or the strand of 20Ne～80Ne, and single twist is 500～1500T/m, and strand twist is 270～1500T/m.
Described fine denier modal fiber blended color spinning, other fiber can be various chemical fibres or cotton fiber etc.For the fabric that this yarn is knitted make has good wearability, prevent from dress, use, washing process, to occur phenomenons such as stretcher strain, can in blended color spinning yarn, add spandex filament, make spandex core-spun yarn or wrap yarn.
The present invention makes traditional spinning process that spins after stain earlier into technology that elder generation dyes and afterwards spins.Described fine-denier Modal fiber blended color yarn, its production method are the processing of earlier fine denier modal fiber and other fiber being dyeed, and then carry out look and spin production.
Described fine denier modal stock-dye treatment step comprises the boiling-off of fine denier modal fiber or bleaching, dyeing, three steps of post processing.
1, to the pre-treatment of fine denier modal fiber, i.e. boiling-off:
Bath raio is in 5～20 the water at normal temperatures, adds chelated dispersants (2～3 grams per liter), and biology enzyme scouring agent 1% directly is warming up to 55～60 ℃ then, is incubated 30～60 fens kinds; Bleed off whole pin water, washing again cools to the temperature that dyeing needs, as adopts traditional boiling-off fiber strength to reduce greatly.
Or the fine denier modal bulk fibre bleached pre-treatment:
Bath raio is in 5～20 the water at normal temperatures, adds chelated dispersants (2～3 grams per liter), uses NaCO
3Regulate PH=8.5～9.5; Add hydrogen peroxide (6～10g/l) then; hydrogen peroxide stabilizer 197 (3g/L) is warming up to 60～70 ℃ with the speed of 1～2 ℃ of per minute, is incubated 30～60 fens kinds; the raffinate of draining; washed 8～12 minutes, and adding deoxidation enzyme (2～4g/L), in 8～12 fens kinds of 35～45 ℃ of insulations; washing again; cool to the temperature that dyeing needs at last, the selection of SC alkaline agent can be selected special efficacy hydrogen peroxide stabilizer 197 for use in the bleaching process, can play the effect of protection fiber.
2, to the fine denier modal loose stock dyeing: according to different color and luster requirements, the dye ligand ratio, in dye vat, add chelated dispersants, glauber salt, sodium bicarbonate, soda ash, dyeing is 40～60 minutes when putting into fine denier modal bulk fibre through pre-treatment (boiling-off or bleaching) at 60～70 ℃ again.Because the fine denier modal fibre number is very thin, has only 0.9 DENIER, the brute force of fiber itself is very little, utilize traditional dyeing and finishing processing method that fiber is sustained damage, therefore each the road link in dyeing and finishing processing all is noted that because fiber number is very thin, thereby it is not high for common dyestuff tinctorial yield, and dyefastness is not fine, can be with low salt dyestuff, and as the LS type of vapour crust etc.
3, to the post processing of fine denier modal bulk fibre: under 45 ℃～60 ℃, carry out neutralisation treatment earlier, adding concentration is 98% glacial acetic acid (0.4～0.8 grams per liter), then under 70 ℃～80 ℃, soaped 10～20 minutes, add soaping agent RS (2 grams per liter), washed 5～10 minutes 45 ℃～60 ℃ heat, look shade and do 1～2 time, under 45 ℃～60 ℃, carried out the fixation soft treatment 10～20 minutes at last, add hydrophilic softener (2～5 grams per liter) on color-fixing agent (2～3 grams per liter) back.Fine denier modal stock-dye fastness is bad, and the general traditional color-fixing agent such as the color-fixing agent fastness of dicyanamide class can't guarantee and have certain look and become, and therefore need select color-fixing agent such as vapour Ba Gu ECO etc. preferably for use; Its alkali resistance and heat resistance are not fine yet, thereby consumption is no more than 10g/l as far as possible during with the soda ash fixation, can add sodium bicarbonate elder generation fixation, and temperature should not surpass 80 degree.
Because the fine denier modal fibre number is very thin, has only 0.9 DENIER, in the carding machine process, shift difficulty, easily twine cylinder, licker-in and doffer cause cotton knot increase in the carded sliver, and fiber directionality in web is poor; Fine denier modal fiber rigidity is little, fineness carefully, easily twist together and damage, therefore reduce cotton junction grain number, improve the extended parallelization of fiber in web, be the key during carding step is produced.Adopt novel thin dawn chemical fibre card clothing model, the short angle of the rare base of its card clothing tooth is big, helps abundant transfer; Adopting tightly spaces helps the raising of fiber separation extended parallelization, reduces the mutual afterturn kink of fiber, makes fiber that directionality preferably be arranged in web.Suitably lengthening feed plate face length can reduce fibre damage; Adopt between cylinder and doffer and tightly space, help the doffer fiber on the cylinder is well on commentaries on classics enough.
Novel thin dawn chemical fibre card clothing model configuration is as follows:
| The card clothing model | Height overall | Operating angle | Vertical tooth pitch | Base is thick | Tooth is close | |
| Bearded-needle knitted cloth | AC2520×01660 | 2.5mm | 70° | 1.6mm | 0.6mm | 713 tooth/square inches |
