Abstract
The invention discloses a method for manufacturing knitted flax fabrics, which comprises the following steps of treatment of weft yarns before weaving, weaving on a machine, and after-treatment. Firstly, flax yarns between 28 and 42 n/1 are steamed in a steam box for 60 to 90 minutes at a temperature of between 90 and 100 DEG C, subjected to heat preservation for 50 to 60 minutes, and woven on a bodkin plain circular knitting machine between 16 and 18 GG, wherein the vehicle speed is set to between 10 and 20 rpm, and the yarn feeding tensile force is between 5 and 6 g; and secondly, fabrics are subjected to rope chromating, and the finished products - the knitted flax fabrics with a weight of 190 grams per square meter are finally obtained. Therefore, the flax fabrics woven by the circular knitting machine have the advantages of soft hand feeling, good elasticity and good air permeability; and the method effectively reduces tears of the fabrics during the weaving process of the circular knitting machine and makes weaving and looping formation become smooth, so that the method reduces the defective rate during the process of mass production.
Description
Technical field
The present invention relates to a kind of preparation method of sodolin, relate in particular to a preparation method that grows flax knitted fabric, belong to the knitting technology field.
Background technology
Sodolin is knitted system by tatting technology usually at present, specifically, correspondingly upward arranging cheese and on warping machines, carrying out warping by technological requirement through the sliver number, to connect warp thread through axle again after warping finishes together is installed on the loom, on the weft yarn frame of loom cheese is installed, adjust weaving process parameter, start Rapier looms and realize that warp and weft interweaving forms flax woven, because the Rapier looms varietal adaptation is wide, flax material is suitable for weaving smoothly on Rapier looms fully, so be widely adopted in the tatting technology of weaving field flax.But flax woven since elasticity a little less than, the cause of pliability deficiency, the class that occupies on market is lower.
For this reason, industry transfers to attempt the braiding sodolin on circular knitting machine, the sodolin that utilizes circular machine knitting to form has that feel is soft, elasticity is good, good permeability and the characteristics that do not crease easily, but owing to one side linen yarn ultrahard, the crisp characteristic of spy, the crooked lopping of yarn is difficult in the braiding process, and yarn is easy to generate broken hole in knocking over and knitting cycle, cause defect rate high, can't satisfy client's quality requirement, on the other hand, because the linen yarn spinnability is poor, bar is done inequality ring, also is the reason that easily causes producing in the braiding process broken hole.
Summary of the invention
The technical assignment that the present invention is directed to the deficiency of the problems referred to above and propose is to provide a preparation method that grows flax knitted fabric, makes linen yarn braiding smoothly on circular knitting machine, eliminates the generation of broken hole in the braiding process in batches, to reduce the generation of braiding defect rate.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
One preparation method that grows flax knitted fabric the steps include: that (one) yarn knits pre-treatment; (2) knitting; (3) back arrangement, described yarn are knitted pre-treatment and are meant that selected yarn count specification is the linen yarn of 28n/l, and the yarn steaming temperature is 90 ℃-100 ℃, and the yarn steaming time is 60-90 minute, and temperature retention time is 50-60 minute; Described back arrangement is meant down the strong dyeing processing of restricting of the fabric behind the machine.
The step of the strong dyeing of above-mentioned rope is:
(1) scouring and bleaching, temperature is 90 ℃-100 ℃, and the time is 50-60 minute;
(2) dyeing, temperature is 65 ℃-75 ℃, the time is 60-90 minute.
Beneficial effect of the present invention: both kept sodolin that circular machine knitting forms and have that feel is soft, elasticity is good, good permeability and the advantage that do not crease easily, effectively reduce the generation of fabric broken hole in the circular machine knitting process again, the braiding lopping is become smoothly, thereby reduced the defect rate when producing in batches.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the process flow diagram of the preparation method of sodolin of the present invention.
The specific embodiment
Below with the finished product door width of cloth be 26inch * 2 width of cloth, finished product grammes per square metre be 190 grams/square metre lateral density be 40 orders/5 centimetre, vertically density is that the single face linen cambric of 66 orders/5 centimetre is an example, its operating procedure is as follows:
Yarn steaming: weave test through repeatedly strict, the yarn count specification of selected linen yarn is 28n/l at last, that flax sliver of this yarn count is done is stable, spinnability is good, the linen yarn of 28n/l is carried out the yarn steaming processing before last machine, select suitable temperature and time yarn steaming, yarn steaming technology: 100 ℃ of steamings were incubated 1 hour in 1 hour again, to increase humidity, brute force and the pliability of flax, the bending of yarn circle when being beneficial to lopping.
Knitting: weave test through repeatedly strict, it is 40 orders/5 centimetre that the knitting technology of single face linen cambric is set at lateral density, and vertically density is 66 orders/5 centimetre.Because it is poor that the bar of flax is done, can not use the garden machine of thin plane No. when selecting machinery equipment, and to select the circular knitting machine of bodkin distance, specifically selecting 18GG, the door width of cloth for use is that the single-side machine of 30inch is comparatively desirable, can reduce the chance that broken hole produces better, and institutional framework is chosen the braiding of single face plain weave, adjust yarn tension, advancing yarn tension can not be too big and too little, otherwise is prone to broken hole, advances yarn tension and is controlled at 5g.Place 40 tunnel yarn production, tractive tension force is pine too, otherwise moving back circle has any problem, easily produce magnificent pin and broken hole, tractive tension force is transferred to 4 grades of comparatively ideals, and the speed of machine is also unsuitable fast, select about 15 rev/mins, in addition workshop moisture temperature is controlled, temperature generally is controlled at 20-30 ℃, and humidity is about 65-75%.If the workshop humidity deficit also can increase difficulty of weaving, increase broken hole, machine grammes per square metre 165 grams under the grey cloth of production/square metre, the fabric of this grammes per square metre is fit to make top grade class clothes in spring and autumn.
The back arrangement: the back arrangement of flax knitted fabric also is very important, if it is improper to control, equally also can produce a lot of broken holes, influence fabric quality, colouring method will dye with rope is strong, and can not use overflow dyeing, because speed is fast during overflow dyeing, pulling force is big, can make lining produce broken hole in dyeing course, the strong dyeing of rope comprises two steps of scouringing and bleaching and dye, and the conventional non-natural fiber-like of time ratio of scouringing and bleaching product reduces 20~30 minutes, generally be controlled at about 55 minutes, the temperature of scouringing and bleaching is controlled at 90 ℃, and dyeing temperature is 70 ℃, and the time is 75 minutes, flax knitted fabric broken hole that adopts above-mentioned series of process to produce can be controlled in 0~5 fault/, satisfied client's quality requirement.
