Description
Technical field
The present invention relates to a kind ofly match that network spins or Seluofle spins the method for producing hemp high grade yarn and strand, belong to the Textile Engineering technical field.
Background technology
Hemp is a kind of natural fabric of function admirable, and humidity absorption and release is fast, good permeability, is desirable wearing fabric in summer.Just there is the record that flax spinning is used in China before more than 3000 years.Afterwards, because the tetrahydrocannabinol that contains in the cannabis plants is a kind of of drugs, therefore, the plantation to hemp had strict regulation in the world, had only tetrahydrocannabinol content just to be allowed to plantation less than the hemp kind of setting.Current, along with international community to natural fabric development of resources more and more pay attention to, the order of forbidding cultivating of hemp with good characteristic is also phased out, hemp just more and more obtains more applications.At present big hemp spinning yarn mainly is the form that adopts wet spinning, also is that thicker process of fiber (being fibre bundle) spins after adopting half deguming.Because hemp is thick and the particularity of wet spinning process and equipment, makes the wet spinning of hemp be difficult to spin thinner yarn, can only make thick thick lining.At present, the spinning process of hemp wet spinning mainly is: after the fiber process combing slivering, form hempen fibres through operations such as drafting, rove, roving boiling and bleaching, spun yarn wet spinning, drying, winders again.At present, the fineness of hemp wet-spun yarn public of 16-24 normally.More than 36 public is exactly high grade yarn.And 50 public and above yarn, owing to the requirement height to the hemp raw material, and production efficiency is low, and it is few that the historical facts or anecdotes border produces.
There is being fiber thick and be difficult in the spinning of ramie, wool spinning etc. of high-count yarn spun equally, had the technology that adopts the water soluble vinylon companion to spin, promptly, polyvinyl alcohol fibre is mixed through shredding, combing with ramie or wool fibre, carry out grilling, rove and spun yarn again, spin the blended yarn of ramie/polyvinyl or hair/polyvinyl, with the polyvinyl dissolving, obtain the thinner high grade yarn of fineness again.Production method as ZL200810207888.0 (production method of ramie high grade folded yarn), CN200910045392.2(ramie high-count yarn spun and strand), CN 200910051980.7(matches the production method that network spins ramie high grade yarn and Gao Zhi strand for one kind) etc.But, because the ramie and the wool spinning of wet spinning of hemp and dry method spinning have very big difference, in the wet spinning, hemp will float to improve spinnability through over-cooking after making rove, and in spun yarn processing, rove also will just form hemp wet-spun yarn at last earlier through entering the drawing-off zone of spun yarn behind the tank again.Therefore, water soluble vinylon can't just mix with hemp before spinning process, and this has limited the feasibility that hemp and water soluble vinylon blending or companion are spun greatly.
Because the existence of the problems referred to above makes to be difficult to produce high, expensive goods in the existing hemp wet spinning, is unfavorable for the diversified development of hemp product variety, has limited the promotion and application of big ramie product to a great extent, has restricted the development of hemp industry.

Further, the mixed method of described hemp rove and water soluble vinylon rove is: the draw zone that the hemp rove is entered jointly fine spining machine through tank (in establish cord roller) and water soluble vinylon rove, to guarantee that the water soluble vinylon rove is not subjected in the tank of wet spinning frame the liquid dissolving and damages, after drawing-off through rear roller, back roller, light top roller, single apron, front roller and front leather roller, mix the twisting resultant yarn in output place.Because the fineness of soluble vinylon fiber is thin, good spinnability, therefore, the blended yarn fineness of hemp/water soluble vinylon can be than the fineness height of conventional hempen fibre.
In the draw zone of fine spining machine, the spacing of hemp rove and water soluble vinylon rove remains on 0～14mm.
Control for strengthening in the wet spinning drawing-off the relative short polyvinyl alcohol fibre of length being moved guarantees the uniformity that blended yarn bar evenness and polyvinyl alcohol fibre distribute in yarn, the twist factor of water soluble vinylon rove is 1.2-1.5 a times of hemp roving twist factor.
The mixed method of described hemp rove and water soluble vinylon rove also can be: after will passing through the drawing-off of wet spinning frame through the hemp rove of tank, mix with water soluble vinylon single thread or long filament at the front roller place, the twisting back forms the blended yarn of hemp/water soluble vinylon.Because the single thread of water soluble vinylon or the existence of long filament improve the spinnability of hemp greatly, the fineness of its blended yarn can be higher than the fineness of conventional hempen fibre.At the front roller place of fine spining machine, the spacing of hemp rove and water soluble vinylon single thread or long filament remains on 0～14mm.
Water soluble vinylon content is 10～70wt% in the described blended yarn, and hemp content is 30～90wt%.
The solution temperature of the described polyvinyl of decorporating is 100 ℃, and the polyvinyl time of decorporating is 0.5～6 hour.
The fineness of described hemp high grade yarn is 50～150 public, and the fineness of the high strand of hemp is 50/2～150/2 public.
The single twist multiplier of described blended yarn is 0.80～1.2, and the ratio of the twist factor of the high strand of hemp and the single twist multiplier of blended yarn is 0.9-1.3.
Beneficial effect of the present invention is as follows:
1, in hemp wet spinning process process, adopt the present invention can easily realize the blending of conventional hemp and soluble vinylon fiber, spin out the thinner hemp of fineness/water soluble vinylon blended yarn;
2, because fiber random alignment normally on the length direction of yarn, it is uneven that fiber number on certain segment length distributes, and the mode that adopts hemp rove of the present invention and water soluble vinylon rove to mix, help of the even distribution of the fiber of hemp and water soluble vinylon, significantly reduced owing to polyvinyl alcohol fibre causes the few yarn section of polyvinyl alcohol fibre to produce the probability of broken end at the length direction skewness of yarn at the sliver length direction;
3, adopt Seluofle, the mode that to be the hemp rove mix at wet spinning frame front roller place with the yarn or the long filament of water soluble vinylon, the yarn of water soluble vinylon or long filament need not drawing-offs, the difference that can avoid soluble vinylon fiber in drawing-off, to move, thereby the quality of raising blended yarn with hemp;
4, it is few and cost an arm and a leg to be used to spin the high-quality fiber number of a high hempen fibre, and the production of a high hempen fibre is difficulty relatively, has limited the Application Areas of big ramie product.Therefore, adopt the water soluble vinylon companion to spin and to spin the hemp high grade yarn with conventional hemp, and on wet spinning frame, realize the method that hemp and polyvinyl mix with this method, can spin out brute force is even, bar evenness is good, the fiber crops grain is few high-quality hempen fibre, line.
