Abstract
The invention provides a production method of ramie spinning high grade plied yarn, which is characterized by comprising the steps: union yarn is manufactured by cospinning ramie and water-soluble vinylon, is boiled by water for vinylon dissolution, and then is rinsed and dried, so that ramie single yarn with the fineness of 100-300Nm; then, the plied single yarn is made into ramie pliedyarn having the fineness of 100/2-300/2Nm. The production method has the advantages that as the water-soluble vinylon is introduced, the spinnability of the ramie is improved, and the spinnable fineness of the ramie yarn and thread is greatly reduced; furthermore, the single twist multiplier can be properly reduced, and the coefficient of twist of the plied yarn can be selected reasonably according to the twisting theory, so that the resultant yarn structure of the plied yarn is more compact, the yarn body is brighter and cleaner, less filoplume is available, and the uniformity of yarn levelness is better, thus ensuring the whole quality of the plied yarn to be excellent. Therefore, the excellent properties of the ramie are fully exerted, the application scope of the ramie products is enlarged, and the method is suitable for producing the thin ramie products with high quality.
Description
Technical field
The present invention relates to a kind of ramie and spin the production method of a high strand, belong to the Textile Engineering technical field.
Background technology
Ramee is powerful high, moisture absorption, diffusing wet fast, and good permeability, antibacterial, have good wearability, be a kind of green textile raw material of extensively being favored.But because of its fiber rigidity is big, stiffening, flexible not enough, it is low many with filoplume to cause into yarn count, can spin low (public an of 36-48), and its woven fabric prodding and itching feeling is strong, causes the application of ramie product limited.People are devoted to the research of the high branching of ramie for a long time, but make progress limited, the method of existing ramie high-count yarn spun adopts ramie and water soluble vinylon blending to make blended yarn usually, is made into behind the fabric in back arrangement process polyvinyl to be dissolved away, and the high-count of the ramie yarn in the cloth can reach 300.
But there is following problem in existing method: though the number of ramie yarn is very high in the fabric that is made into, but can not make independent height and prop up ramie yarn, and after water soluble vinylon decorporated, the density of ramie fabric and brute force were very low, gauze kerchief etc. can only be used to do, DRESS FABRIC etc. can not be done.Make the quality and variety of the product that the method for existing ramie high-count yarn spun produces limited, limited the promotion and application of ramie product to a great extent, restricted the development of ramie industry.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned spinning method, the production method that provides a kind of ramie to spin a high strand obtains the high-quality ramie high grade folded yarn.
In order to achieve the above object, technical scheme of the present invention provides the production method that a kind of ramie is spun a high strand, it is characterized in that, concrete steps are: ramie and water soluble vinylon blending are made blended yarn, the blended yarn poach is moved back dimension, washing and oven dry, and to make fineness be 100～300 public ramie single thread, the single thread plying made the ramie plied yarn of 100/2～300/2 public of fineness.
Further, ramee and the mixed method of soluble vinylon fiber are preferably that bulk fibre mixes or the ramie rove are mixed on fine spining machine with water soluble vinylon filament in the described method of ramee and soluble vinylon fiber blending being made blended yarn.
Described with ramie rove and water soluble vinylon filament on fine spining machine in the mixed process, the spacing before the ramie rove mixes with water soluble vinylon filament is preferably 0～8mm.
Water soluble vinylon content is preferably 10～70wt% in the described blended yarn, and ramie content is preferably 30～90wt%.
The described polyvinyl temperature of decorporating is preferably 30 ℃～100 ℃, and the polyvinyl time of decorporating is preferably 0.5～4 hour.
The preferred auxiliary agent that adds in the described polyvinyl process of decorporating.
Described auxiliary agent is preferably NaOH and JFC.
Described bake out temperature is preferably 50 ℃～120 ℃, and drying time is preferably 0.5～6 hour.
The twist factor of described ramie single thread is preferably 80～140, and the twist factor of ramie plied yarn is preferably 70～170.
Utilize this method, can be according to relevant twisted theory, that is: work as α
Strand＜α
Single thread, the strand of formation becomes tight structure in the outer pine, brute force, rigidity, returns that to endure property poor.Work as α
Strand＞α
Single threadThe time, the powerful general brute force of strand greater than single thread, and work as α
Strand=(1.2～1.4) α
Single threadThe time strand structure be outer in the degree of tightness unanimity, powerful high, generally with the woven warp thread of using.α
Strand≈ α
Single threadThe time, the fiber axis tropism on the strand surface of production is good, and the gloss of strand and axial ABRASION RESISTANCE are good, and soft.General as knitting yarn and weft yarn.Therefore, can select different ply twist multipliers targetedly according to the quality of single thread and the purposes of strand, bar is done evenly to obtain, brute force ramie plied yarn higher, that the yarn body is bright and clean.
Beneficial effect of the present invention is as follows:
(1) water soluble vinylon is introduced, and has improved the spinnability of ramie, greatly reduces the fineness spun of ramie yarn, line;
What (2) this kind method adopted is to move back dimension earlier to pool capital again, the strand of producing with moving back dimension behind the direct plying is again compared, it is at when plying twist factor of choose reasonable strand as required, make that strand yarn formation structure behind the plying is tightr, the yarn body is brighter and cleaner, filoplume still less, that bar is done uniformity is better, thereby make the total quality of strand more excellent;
(3) strand that can utilize this method to produce can be given full play to the premium properties of ramie, produces the thin post that approaches and have suitable density, enlarges the Application Areas of ramie product.
