In weaving process, knitting requires much higher than weaving to the pliability of yarn, brute force, elasticity, fracture elongation etc.And in knitting, circular knitting machine than straight-bar machines to the pliability of yarn, brute force, elasticity, fracture elongation require taller.Therefore, we can say that tubular knitting technology is the strictest in the various weaving process, the harshest to the requirement of yarn qualities.

The present invention is polychrome collection layer flax drapery, selects for use the linen yarn of high-quality to weave and forms, and can machine-wash repeatedly, machine gets rid of, exempt from flatiron, outward appearance exquisiteness, corrugationless.The present invention has replenished the blank of domestic knitting pure ramie product, leading domestic technique level.

The invention solves the following technical barrier:

(1), single thread or single cord feeding, the leak that broken yarn forms, a difficult difficult problem of repairing have been solved.

(2), the yarn process channel has strict requirement to the thickness (number) of thigh yarn feeding, be because the number of strand yarn one regularly, its thickness degree is also just basic have been determined.And two yarns enter the process of weaving area under unwinding from the tower yarn when adopting two single thread feeding, can automatically compensate the size of drafting stress mutually, and in the slit that process channel provides by roll mutually, laminate, multiple mode such as side subsides automatically offsets drafting tension and avoids the generation of breaking end.

4, adopt yarn to go into the preceding broken end of machine and stop to feed mechanism automatically

The research that the broken end yarn is gone into the preceding automatic shutdown protection mechanism of machine is to solve the broken end yarn to enter the technical guarantee that causes product card yarn, leak, slippage in the machine.Because of the present invention has adopted the feeding of two yarns, the judgement of making the mistake for unavoidably the broken yarn sweep mechanism of former machine design.For this reason, the present invention intends increasing newly the computer automatic controlled system of a cover, the state when controlling every one thread and going into machine.Thereby for knitting technology provides new technical guarantee.

Production technology of the present invention overcomes and has solved in the circular knitting machine weaving process equipment technology reconstruction difficult problem that the two yarn feeding technology of even tension force and two yarn breakage yarns stop hello technology automatically.Solved the technical barrier of shrinkproof, wrinkle resistant, the typing finishing technique in the knitted fabric post-finishing.

The specific embodiment:

The present invention is a kind of preparation technology of polychrome collection floor height shelves flax knit goods,

1, get the raw materials ready: the yarn of required color is standby;

2, carry out clearing dying good yarn: yarn is eliminated ring and numb particle in the linen thread and yarn earlier through bobbin winder, crosses wax: yarn is through having the wax stone of centre bore, and yarn is by bobbin winder, and network becomes quality to be fit to the tower yarn of circular knitting machine braiding;

3, the color sequences that presets according to the computer jacquard large circle machine of the qualified tower yarn that network is good is placed on the creel around the large circle machine, again the yarn of the per two same colors of tower yarn that are divided into group is sent into a yarn feeding mouth of computer jacquard large circle machine, be arranged in order and be called two yarns feedings;
