Description
Technical field
The present invention relates to textile manufacturing techniques fields, specifically, being a kind of air vortex spinning knitting fabric and its work of weaving
Skill.
Background technique
Knitted dress has the advantages of good productivity and adaptability, especially functionality etc. for woven garment institute
It cannot replace, rapidly develop knitted dress industry.Since the 1980s, knitted dress day within the scope of All Around The World
Benefit has been favored by people, and world clothing field shows the gesture developed to knitted dress.Fabric is knitted as in knitted dress
An important class, the general general character of existing knitted dress, and have distinctive individual character is soft, comfortable, fit and rich with it
The excellent performance of elasticity forms style alone.Especially into the new century, it is knitted the Leisure orchards of fabric, fashion is complied with
The variation of people's lives mode, raw material develops to natural and environmentally friendly development, fabric to functionalization, in modern clothing industry
Increasingly consequence is occupied, indispensable a part in modern's wearing pose is become, obtains development prospect with wide
And huge commercial opportunities.
Air-jet eddy-current spinning (MVS) is one kind that Japanese Murata is successfully developed on the basis of sir jet spinning machines (MJS)
The spinning machine of update.Air-jet eddy-current spinning (MVS) is both different from RING SPINNING, and also different from Revolving cup spinning, it is fed and passed through by sliver
It crosses after four rollers (or five rollers) draft mechanism drawing-off and reaches the parallel fibers beam of the count of yarn of needs, in the effect of negative pressure
Under be inhaled into nozzle.The front end of fibre bundle around guid needle, by the tail end for forming yarn pull and import and draw yarn
Guan Zhong；And effect of the rear end of fibre bundle by high-speed eddy axial thrust load, few fibers fall in doffing tube inlet in umbrella
Shape, the fiber of shape is just exposed in the gyration airflow of spray orifice ejection.It is twisted on yarn tail with the revolution of air-flow, forms the short of real twirl shape
Silvalin output, fibre bundle all can control along the angle of spindle looping and angle of revolution.
Air-jet eddy-current spinning (MVS) uses rotating vortex without revolution at a high speed parts (spindle in such as RING SPINNING, wire loop etc.)
Resultant yarn is twisted, higher than mechanical twisting efficiency, the vortex of revolution at a high speed only acts on fiber, the fiber drawn with front roller
Function is formed together the effect of the twisting to fiber, and high-speed eddy has no effect on the height of the count of yarn other than completing twisting task
It is low, therefore can realize high-speed spinning, most high-speed spinning is practical up to 380m/min, and the yield of every ingot is equivalent to RING SPINNING single ingot yield
22 times or so.Since fiber is formed true twirl, this spy by air-jet eddy-current and winding roller effect with the velocity of sound
Different twisting effect is that Other spinning machines tool cannot replace, and the yarn formation structure under the high cyclotron velocity of yarn is than ring spun yarn line
Structure is more closely and stable.
But when the production of air-jet eddy-current spinning yarn, find manufactured yarn qualities it is difficult to ensure that uniformity, weaving process
It is difficult to control, and due to the distinctive looping structure of vortex spinning yarn, feel is harder, and the wearability of institute's knitted fabric needs to be mentioned
It is high.
Summary of the invention
The purpose of the present invention is to provide a kind of air vortex spinning knitting fabric and its textile technology, the web process are easily-controllable
System, fabric hand feel is soft, wearability is good.
The object of the present invention is achieved like this: it is single side plain that air vortex spinning, which is knitted fabric tissue, horizontal close: 44.5 is vertical
Row/10cm；It indulges close: 60 rows/10cm；Needle number: 12G weaves on Computerized flat knitting machine.Yarn: 20S polyacrylonitrile fibre is used.
Grammes per square metre: 255 grams/m.
Product process flow
Air injection air vortex spinning → rewinding → knits piece → running-on → flatcar → hand seam → washing → drying → whole boiling hot → packaging → storage.
Conditioning is carried out to polyacrylonitrile fibre by the way of pre-dewing before air injection air vortex spinning, makes the aqueous of yarn
Rate reaches 12%-16%.
During air injection air vortex spinning, drawing yarn speed is 240m/min, and spinning air pressure is 0.63Mpa, and suture introducing needle length is
0.89-0.92 is compared in 1.7mm, injection diameter 0.53mm, feeding.
The whole boiling hot process of fabric carries out soft treatment to fabric using pectase.
The advantages and beneficial effects of the present invention are:
(1) combined optimization is carried out to pretreatment and yarning process parameter.
(2) to enhance its yarn, reasonable disposition optimization is carried out to the influence twist and looping structure relevant parameter.
The present invention makes full use of vortex spinning yarn looping structure feature, using polyacrylonitrile fibre as raw material, by it
The pretreatment of raw material and optimization Technology of Air Vortex Spinning parameter are knitted fabric to develop a kind of air vortex spinning.
Air vortex spinning of the present invention is knitted fabric sponginess, and moisture absorption good air permeability has preferable anti pilling feature and class strand
As texture style, have a vast market development prospect.
