Abstract
The invention relates to a device and method for producing weft knitting single-face concave-convex jacquard terry fabric. According to the knitting method and device, on a common weft knitting double-face computer jacquard knitting machine, a drop stitch technology is combined, an electronic needle choosing principle is used, and front face jacquard three-dimensional concave-convex terry fabric is formed by knitting according to pattern demands. The defects that existing mechanical weft knitting jacquard terry fabric is simple in structure and small in variation, and the design is limited are overcome. Meanwhile, the jacquard effect can rival that of products of the computer jacquard knitting machine, and the three-dimensional concave-convex jacquard terry fabric can be woven according to needs. The provided fabric is stable in structure, small in longitudinal and horizontal extension, stiff and smooth, wide in raw material applicability, and capable of enabling multiple raw materials such as various wool, fiber, silk, chemical fiber and cotton to be used as terry yarn and primary structure weft yarn of single-face terry fabric. The advantages of various materials are fully utilized, the performance of the fabric is improved, the fabric cost is lowered, and the product range of a double-face jacquard circular knitting machine is expanded. According to the device and method, the structure is simple, and the yield is high.
Description
Technical field
The present invention relates to weft-knitted jacquard terry fabric production technical field, disclose especially a kind of Apparatus and method for of the one side jacquard terry fabric of producing based on weft-knitted Double-plate machine.
Background technology
Weft knitting knop cloth refers to that the surface producing on pile knitting machine has a kind fabric of Di-loop process.These fabrics have Circular Single Terry Machine, two-sided terry, jacquard terry fabric etc.Because the coil of knitted fabric can shift mutually after stressed, therefore, the vertical horizontal extension of general knitted loop fabric is large, yielding, not well-pressed, and application is restricted.
At present, weft-knitted knop cloth is mainly still produced on special pile knitting machine, and computermatic jacquard weave looped pile is characterized in that design software operation is comparatively complicated, high to designer's technical ability requirement, and the loss that the looped pile of long flotation line connection spends type to need cropping to cause is large; And mechanical jacquard weave looped pile, flower type structure is simple, variation is less, and the renovation of flower type is slow.
Summary of the invention
The object of patent of the present invention is that a class weft knitting one side jacquard terry fabric will be provided---produces at common two-sided computer jacquard circle latitude machine, can knit out as required and there is relief concavo-convex jacquard terry fabric in conjunction with empty needle technology.Overcome existing machinery formula weft knitting jacquard terry fabric flower type structure simple, change little, design restricted shortcomings and deficiencies, jacquard effect can compare favourably with the product of special computermatic jacquard wool ring machine simultaneously.
The invention has the advantages that the Stability Analysis of Structures of provided fabric, vertical horizontal extension are little, well-pressed; Adaptability to raw materials is wide, can make plurality of raw materials, as various hairs, fiber crops, silk, chemical fibre, cotton etc. are done terry yarn, elementary organization's weft yarn of Circular Single Terry Machine fabric, make full use of the advantage of various materials, improve fabric property, reduce fabric cost, expanded the product scope of double-faced jacquard large circle machine.Equipment provided by the invention and method, simple in structure, output is high.
For realizing above object, the technical scheme that patent of the present invention adopts is:
A kind of weft-knitted one side jacquard terry fabric weaves on double-faced jacquard large circle machine, using two-sided alternative construction as elementary organization, utilizes syringe electronic needle selecting device, carries out jacquard weave according to flower type information, forms the jacquard weave looped pile with concave-convex effect.
Described electronic needle selecting device, utilizes piezoelectric ceramics to control the action of knitting needle, in conjunction with pattern data file and empty needle technology, realizes the jacquard weave to looped pile district, non-looped pile district.
Described double-faced jacquard circular knitting machine, the high and low heel working needle 1 of its dials configures every 1 row's pin, normally weaves formation organize along fixing dials triangle, and syringe utilizes empty needle technology to form looped pile.
Described pattern data file, utilize different colours to distinguish looped pile and non-looped pile region, and paving is with corresponding looped pile and non-pile stitch, finally generates corresponding file and controls braiding in the time of the design of flower type.
Described empty needle technology, does not entry at the yarn mouth that specific cam system is corresponding, and knitting needle 1 every 1 withdrawal of needle, but does not hook and gets yarn under the effect of stitch cam, forms independent looped pile after knocking over.
The production method of weft knitting one side jacquard terry fabric, the steps include:
1, the configuration of entrying: as shown in Figure 1, yarn with the circulation of entrying fixed around circular knitting machine.Solid line represents to have worn yarn, and dotted line represents that sky wears, and does not entry at the corresponding yarn mouth of this cam system, and knitting needle does not hook gets yarn, forms independent looped pile after knocking over.For ensureing to form the looped pile of certain density, generally adopt 1 to wear 1 empty or 2 rules of wearing 1 sky and entry, form looped pile every 1 road or 2 tunnels, reduce looped pile longitudinal pitch.
2, pattern data: in jacquard weave looped pile software, design as required pattern data information, utilize different colours representative to distinguish hairiness circle or without looped pile district.As shown in Figure 2, Dark grey A representative has looped pile district, and light grey B represents without hair-fields.Having hair-fields A and non-looped pile B to fill respectively corresponding pile stitch and non-pile stitch, and these tissues need the rule design of entrying in conjunction with this empty needle technology simultaneously.Pattern data information is converted to the machine file of controlled weaving pin work, just can control actual weaving.
3, looming weaving: machine file is imported in the control system of needle selecting device of electronic jacquard, needle selecting device of electronic jacquard is controlled braiding according to machine fileinfo, but electronic patterning unit only carries out height control to cyclinder needle, coverer is along fixing dials triangle track action.
In looped pile region, electronic jacquard blade is not chosen cylinder knitting needle, and cylinder knitting needle is along normal lopping orbital motion.As shown in Fig. 3 (1), cylinder knitting needle enters working region, Kong Sha has risen needle knitting on road, and get yarn and cannot form new coil because not hooking in the time of decline kinking, after the knocking over of old friend's coil, formed independent looped pile, and coverer grips old coil all the time in dials triangle rail effect; Without looped pile region, electronic jacquard blade chooses cylinder knitting needle to make it along flotation line orbital motion, and as the braiding of not rising of Fig. 3 (2) cylinder knitting needle, Ji Kongsha road knitting needle grips old coil all the time, finally cannot form looped pile, and coverer grips all the time old coil under the effect of dials triangle.
4, after lower machine, fabric carries out the arrangement of conventional Hou road.
The technical problem that the present invention solves is:
The work of the design control knitting needle that needle selecting device of electronic jacquard provides according to jacquard terry fabric design software, the knocking over of Kong Sha road forms looped pile, realize looped pile district and produce weft-knitted one side jacquard terry fabric without the cooperation in looped pile district, overcome existing machinery formula weft knitting jacquard terry fabric flower type structure simple, change little, design restricted shortcomings and deficiencies, jacquard effect can compare favourably with the product of special computermatic jacquard wool ring machine simultaneously.
