Description
Technical field
The utility model relates to the device of using on a kind of textile machine, particularly produces the special-purpose spinneret assembly of viscose filament with abnormal section, belongs to technical field of textile machine.
Background technology
Viscose filament yarn is a kind of colory textile raw material, with its be the textiles of raw material have good moisture absorption, ventilative, soft, dangle and good characteristics such as antistatic, these characteristics be many synthetic fiber can not compare.Continuous lifting along with modern people's health idea and fashion eye, consumers in general progressively improve the requirement of fashion-orientation, comfortableization and the health care of clothing fabric, and existing product structure, far can not satisfy the demand in market, differential, the functionalization kind of exploitation viscose filament yarn, to the diversified development of product, be the direction of current viscose filament yarn development.The production process of viscose filament yarn is that cellulose is generated alkali cellulose through after the basification, generates sodium cellulose xanthate with the CS2 reaction, makes viscose through dissolving, obtains viscose filament yarn through spinning again under the effect of acid bath.In said process, spinning head is an important devices that forms strand, and the shape of spinneret hole, structure, parameter have determined the cross sectional shape and the size of strand.Spinneret orifice on the common spinning head is a circular cross-section, so the cross sectional shape of the viscose filament yarn of producing is a near round shape.Having developed flat cross section silk and three leaf cross section silks at present, and dropped into and produce in batches, is the fabric that raw material is spun into them, all is greatly improved than common quality on gloss, feel and style.But this far can not meet the need of market, thereby, further develop the differentiated product of viscose filament yarn, for the added value that improves the viscose filament yarn fabric, expand its Application Areas, enlarge occupation rate of market and all have positive promote significance.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of spinneret assembly that is used to produce viscose filament with abnormal section is provided, thereby produces the viscose filament with abnormal section with " ten " or " X " tee section.
The alleged problem of the utility model is solved by following technical scheme:
A kind of spinneret assembly that is used to produce viscose filament with abnormal section, it is made up of spinneret cap, spinning head, filter cloth and pad, wherein, spinning head, filter cloth and pad are assembled in the spinneret cap successively, the cross sectional shape of spinning head is thin-walled " ∏ " shape, uniform spinneret orifice on the concave surface, its special feature is: the cross sectional shape of described spinneret orifice is " ten " shape, and the length-width ratio of the every branches and leaves in exit in hole is 3～10: 1.
The above-mentioned spinneret assembly that is used to produce viscose filament with abnormal section, the cross of described spinneret orifice are 90 degree and distribute, and the top of branches and leaves is a circular curve, each branches and leaves connecting portion smooth transition of the porch in hole.
The above-mentioned spinneret assembly that is used to produce viscose filament with abnormal section, the importing angle B of described spinneret orifice duct lead-in portion is 25～35 °, long 0.12～0.4 millimeter of the exit leaf in hole, leaf is wide 0.03～0.05 millimeter.
The above-mentioned spinneret assembly that is used to produce viscose filament with abnormal section, the described spinneret orifice hole heart is distributed on the same circumference.
The utility model is for adapting to the needs of producing viscose filament with abnormal section, specialized designs has the spinneret assembly of cross pass, it is formed the Changing Pattern of viscose glue thread by ejection back, aperture according to viscose glue, appropriate design aperture and duct size, cooperate corresponding technological conditions can produce the special-shaped viscose filament yarn of " ten " or " X " tee section, except that have common viscose filament yarn softness, smooth, dangle and good dyeability and performance such as antistatic, also make fabric dry and comfortable, comfortable, it leads the fabric that wet, perspire, gas permeability are better than other cross sectional shape.Big with its " silk volume space " under the weight, the fluffy ventilative and high resilience of fabric, absorption and the air capacity of preserving are big, have better dual regulation cool in summer and warm in winter than existing flat filament, three leaf silks, be fashion, comfortable, the desirable feedstock of functional textile.

Each label list is shown among the figure: 1. spinning head; 2. spinneret cap; 3. filter cloth; 4. pad; 5. spinneret orifice; 6. the spinneret orifice viscose glue enters the mouth; The outlet of 7 spinneret orifice viscose glues.
The specific embodiment
Referring to Fig. 1, the utility model is made up of spinneret cap 3, spinning head 1, filter cloth 8 and pad 4.Referring to figure, Fig. 3, the cross sectional shape of spinning head 1 is thin-walled " ∏ " shape, and concave bottom surfaces is provided with equally distributed spinneret orifice 2.In the spinning process that viscose glue is produced, spinning head is installed in the spinneret assembly, viscose glue is transported to spinning head accurately through measuring pump, spray with certain speed through the cross duct 2 on the spinning head 1, the cross section is that criss-cross viscose glue thread solidifies, decomposition reaction in the coagulating bath operation, generate the nascent strand of cellulose,, be spun into " ten " or " X " tee section shape with design, the viscose filament yarn that meets the respective standard requirement by the drawing-off of spinning disc and spinning roller.The design of the hole shape of spinning head is a key technology in said process.Viscose glue is subjected to shearing force when entering spinneret orifice population under pressure state effect produces entry-end effect, the viscose glue volume reduces, the elastic energy that is produced is stored in the viscose glue, elastic energy discharges suddenly and resilience takes place when viscose glue ejection aperture, produce the aperture effect that swells, viscose glue swells 2.5～3.5 times during than the duct, and bigger difference takes place for its body and former design shape.Be head it off, cross shaped spinneret orifice has adopted the when rational duct of bigger length and width size, shape and has imported angle, make the viscose glue thread of ejection have higher stretching ability, cooperate the reasonable drawing-off of spinning disc, be spun into satisfactory three leaf viscose filament yarns.
Figure 4 shows that the shape of cruciform vent on the spinning head, Figure 5 shows that the duct shape.The larger-size one side in duct is the population 6 of viscose glue as seen from Figure 5, and size less one side in duct is viscose glue outlet 7.
The reference dimension of spinning head is as follows: 12 millimeters of spinning head recess diameters, 18 millimeters of maximum diameters, 0.27 millimeter of spinning head thickness, long 0.14 millimeter of spinneret orifice outlet position leaf, leaf is wide 0.04 millimeter, 0.19 millimeter of duct lead-in portion length, and the duct imports 30 ° of angles.
