Abstract
The invention relates to a production method for nylon-6 fiber, in particular to a production method for colored nylon DTY glove special-used silk, which mainly solves technical problems that the existing technology can not be used for producing colored nylon, the existing other methods for manufacturing colored nylon has higher cost during dying, and causes environmental pollution, and the manufactured colored nylon has worse elasticity and shrink ability, is not suitable for manufacturing gloves and the like. The production method comprises the following steps: drying color master batches and then adding the color master batches into a color master batch machine, mixing, extruding and melting the color master batches and the nylon slices which are spun, injected, cooled, oiled and woundto form POY, adding the POY into an elasticizer for being elasticized to form grey yarn which is stretched and yarned by a roller, and then heated, cooled, false-twisted in sequence, and oiling and winding again after false-twisted strand silk is secondly rolled to obtain finished colored nylon DTY glove special-used silk.
Description
Technical field
The present invention relates to the production method of a kind of polyamide fibre-6 fiber, especially relate to a kind of production method of colored nylon DTY glove special-used silk.
Background technology
The fabric that traditional common polyamide fibre-6 fiber is processed into, all need dyeing, stamp or bleaching after, just can become the commodity or the semi-finished product of reprocessing.Chinese patent discloses a kind of production method of polyamide fibre 6 micro Denier full-drawn yarns, and (Granted publication number: CN1262694C), it comprises the following steps: 1. fusion successively: the section of polyamide fibre 6 raw materials is imported fusion in the screw extruder, make raw material be molten; 2. moulding: above-mentioned molten mass transport to spinning manifold, is pressed into high potential assembly, forms crin; Wherein the temperature in the spinning manifold is 262～268 ℃; 3. cooling: above-mentioned crin is entered the slow cooling district carry out the slow cooling processing, and carry out lateral blowing and handle, enter the path again and continue cooling; 4. drawing-off: will handle through drawing-off through the crin that 3. step is handled, and form the micro Denier full-drawn yarn; Temperature in the screw extruder is 240～270 ℃, and the The hole diameter of spinneret of high potential assembly is 0.23～0.27mm, Kong Changwei 0.69～0.8lmm, and the aperture of spinnerets is long than being 1: 3 with the hole, and the temperature in slow cooling district is 220～250 ℃; The concrete grammar that drawing-off is handled is: crin through pre-network, after the stretching of the first counter extensioin roller, the second counter extensioin roller stretch, is promptly got the micro Denier full-drawn yarn by the network mouth again, and wherein the speed of the second counter extensioin roller is greater than the speed of the first counter extensioin roller.But this production method can't be used for producing colored nylon, and the expense when the existing method that other make colored nylons then dyes is higher, and causes environmental pollution, and produced colored nylon elasticity and shrinkage are relatively poor, should not be used for making gloves.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of production method of colored nylon DTY glove special-used silk, it mainly is to solve existing in prior technology can't be used for producing colored nylon, expense when the existing method that other make colored nylon then dyes is higher, and cause environmental pollution, produced colored nylon elasticity and shrinkage are relatively poor, should not be used for making the technical problem of gloves etc.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
The production method of a kind of colored nylon DTY glove special-used silk of the present invention is characterized in that:
A. Masterbatch is carried out drying back and adds the Masterbatch machine, then Masterbatch is mixed with slices of caprone and put into screw extruder and carry out extrusion molten, wherein the Masterbatch of Jia Ruing account for mixing afterwards gross mass 2～4%;
B. the mixture after the fusion is put into spinning manifold and carry out spinning, and then feed spinning pack and spray silk, then through being cooled to normal temperature, oiling, be wound into POY;
C. POY is fed elasticizer and add bullet formation precursor, then precursor is stretched oneself and yawn by roller, logical successively again superheated header heating, coldplate are cooled to normal temperature, false twister false twisting;
D. the strand after the false twisting is passed through second roller, by the back coiling and molding that oils, get the finished product colored nylon DTY glove special-used silk again.
Masterbatch will be selected the Masterbatch of good spinning property, by drying, makes it below moisture 700ppm of reaching.Oil then is to be coated with at the strand outer surface that to be covered with spinning oil solution dedicated.Carry out false twisting with false twister and be meant strand is twisted earlier, and then strand is decontroled, make strand no twist after the false twisting, but elasticity has strengthened.
As preferably, the baking temperature of Masterbatch is 80-90 ℃ among the described step a, and be 4～8 hours drying time.
As preferably, the relative viscosity of slices of caprone is 2.4～2.46 among the described step a.
As preferably, the temperature among the described step b in the spinning manifold is 250～265 ℃, and spinning speed is 4100～4250m/min.
As preferably, the draw ratio of stretching oneself and yawn among the described step c is 1.24～1.27, and the D/Y ratio is 2.2～2.4.Because the extension at break of colored nylon POY will be far above the extension at break of common POY, for reaching the required extension at break of DTY, and need higher draw ratio; In addition, for obtaining elasticity, and need to determine D/Y ratio far above conventional DTY far above common DTY.
As preferably, the temperature of hot case is 178～190 ℃ among the described step c, and the processing winding speed is 450～550m/min.When weaving,, when adding bullet, then must adopt higher heater temperature and lower processing winding speed, and make tow add when playing and to be heated fully and to cool off in order to obtain the product of dimensionally stable.
As preferably, in spinning manifold, carry out the strand after the spinning among the described step b, after measuring by spinning pump earlier, feed spinning pack again.
Therefore, the present invention has color and luster and the processing request that the colored nylon color and luster of producing can reach dyeing, under same coloured color and luster effect, the use of Masterbatch, compare with normal dyeing, the processing cost of its gloves can reduce more than 30%, has solved characteristics such as the caused environmental pollution of dyeing simultaneously.
