Description

The dyed yarn process units

Technical field

The utility model relates to the dyed yarn apparatus field, is the dyed yarn process units specifically.

Background technology

In recent years, along with the demand to dyed yarn constantly increases, make the dyed yarn application more and more extensive, particularly nylon 6 dyed yarns, be a kind of low-carbon environment-friendly product, production technology features according to nylon 6 dyed yarns, can be divided into following three classes: (1) hot-rolling does not heat, and normally produces the POY(pre-oriented yarn, the silk of the unstretched and HEAT SETTING of high speed spinning), again through after spin and be processed into DTY dyed yarn (add elater, the stretching with the pre-oriented yarn that before spins production through spinning later elasticizer and twisting become add elater); (2) drawing zone and the shaping area with hot-rolling is set, directly be processed into the FDY dyed yarn (fullly drawn yarn (FDY), on same board, complete high speed spinning, stretching and HEAT SETTING the silk); (3) strand, through special stretching and heat treatment, can be made into the common HTY(high strength yarn of plurality of specifications).But the nylon yarn of above-mentioned production is white or transparent, by knitting the coloured dye printing and dyeing of dye-works's family expenses, become color silk to weave cotton cloth, perhaps be made into white cloth and be dyeing into again painting cloth, its dyeability is unsatisfactory, dye-uptake is low, especially COLOR FASTNESS is not high, and equalization is poor, washes with water easily and fades with the clothes that this kind method makes.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of dyed yarn process units of, intensity high, boiling water shrinkage low dyed yarn high for the production of COLOR FASTNESS.

The technical scheme that its technical problem that solves the utility model adopts is:

The dyed yarn process units, comprise slice hopper, also comprises

Screw extruder, be communicated with slice hopper and receive section;

The functional agglomerate hopper, for to screw extruder, providing color master-batch, be communicated with screw extruder by the masterbatch injection machine;

Spinning manifold, be connected to the discharge end of screw extruder by melt pipe, be provided with in this spinning manifold

Measuring pump and spinning pack, measuring pump is communicated with spinning manifold, and measuring pump is connected along the look fluid flow direction successively with spinning pack;

Oil nozzle, be positioned at the below of spinning pack along spray silk direction;

Drawing roller and setting roll, between oil nozzle and winding head, to the dyed yarn rear typing that first stretches;

Winding head, the dyed yarn after the rolling typing.

Wherein, described spinning pack comprises filter sand, screen pack and spinnerets.

The beneficial effects of the utility model are: the utility model is by being provided for providing to screw extruder functional agglomerate hopper and the masterbatch injection machine of color master-batch, make and with section, be mixed to form painted fluid and after melt pipe and measuring pump, spray colored fibre by spinning pack successively before spinning, adding a certain proportion of color master-batch, colored fibre after oil nozzle oils again through the stretching of drawing roller and the typing of setting roll, just can obtain the low contracting dyed yarn tow that boils of high strength, this tow COLOR FASTNESS is high, be not easy to fade, make dyed yarn especially nylon 6 dyed yarns as the low-carbon environment-friendly product, can access promotion and application more widely, simultaneously, this equipment has been abandoned the dyeing process in the conventional art, can not produce dyeing waste water in process of production, has reduced the pollution to environment, makes with this dyed yarn process units production and has dyed yarn to become a kind of non-aqueous dyeing technique, belongs to environmental protection production.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, dyed yarn process units of the present utility model, comprise slice hopper 1, also comprises screw extruder 2, and this screw extruder 2 is communicated with slice hopper 1 for receiving section (being the nylon particle), functional agglomerate hopper 3, for to screw extruder 2, providing color master-batch, functional agglomerate hopper 3 is communicated with screw extruder 2 by masterbatch injection machine 4, enters color master-batch in screw extruder 2 and the mass ratio of section and is controlled at 2%～10%, spinning manifold 5, by melt pipe 6, be connected to the discharge end of screw extruder 2, section and color master-batch form painted fluid under the extruding of screw rod, painted fluid enters in spinning manifold 5 through melt pipe 6, in this spinning manifold 5, be provided with measuring pump 7 and spinning pack 8, measuring pump 7 is communicated with spinning manifold 5, measuring pump 7 is connected along the look fluid flow direction successively with spinning pack 8, wherein the effect of measuring pump 7 is output quantities of metering melt, in order to control the fiber number size of fiber, spinning pack 8 is for being equipped with filter sand, screen pack, a set of equipment of spinnerets, this is equipped for the known techniques of this area, no longer launch to repeat, oil nozzle 9, be positioned at the below of spinning pack 8 along spray silk direction, and oil nozzle 9, for to strand, oiling, to reduce the friction of strand and parts, reduces static, increases the coherent of strand, drawing roller 10 between oil nozzle 9 and winding head 12 and setting roll 11, drawing roller 10 are for dyed yarn is carried out to stretch processing, and 11 of setting rolls carry out high-temperature shaping to the dyed yarn after stretching, and the coloured strand after typing is by winding head 12 rollings.

Use the processing step of dyed yarn process units production nylon described in the utility model 6 dyed yarns as follows:

A, by color master-batch with 2%～10% part by weight (with the ratio of section) by masterbatch injection machine 4 feeding screw extruders 2, section is mixed in screw rod with color master-batch;

B, by the painted flow of melting through melt pipe 6 and measuring pump 7, and from spinning pack 8, spraying colored fibre;

C, the colored fibre that spinning pack 8 is sprayed oil through oil nozzle 9;

D, the colored fibre after oiling carry out stretch processing by drawing roller 10;

E, the colored fibre after stretching carry out heat treatment through setting roll 11.

F, finally by crossing winding head 12 rollings.

Had by nylon 6 dyed yarns of said method production that intensity is high, COLOR FASTNESS is high, the low good characteristic of boiling water shrinkage (%), these nylon 6 dyed yarns (meaning with HTY look silk) and the common silks such as POY compared as following table:
