Description
Technical field
The present invention relates to textile technology, and in particular to a kind of production technology of air spinning cotton core silk covering yarn.
Background technology
Covering yarn is also known as composite yarn or wrap yarn, it be formed by two or more fiber combinations it is a kind of new
Yarn.Initial covering yarn be using cotton fiber as skin, terylene short fiber yarn be core exploitation chopped fiber and chopped fiber covering yarn.In core
In the selection of wire material, strength and the preferable synthetic filaments of elastic force are used in later development trend as core filaments.The fiber number of core filaments
Wherein monofilament radical, to be selected according to textile applications and spinning count.The core filaments of same fiber number, its monofilament is thinner, root
Number is more, and fabric is more soft smooth；Otherwise radical is fewer, fabric is rigidly good, well-pressed, can also determine according to the actual requirements be
No selection gloss core filaments.General to select polyester-type 7.78tex (70D) spandex thread, its drafting multiple is advisable from 3.8 times or so.
And want bigger than normal for the spandex core-covered silk of warp-wise strength corduroy and the medium size of Expandra (in low branch), spandex filament drafting,
At 3.8-4.0 times or so, it is ensured that when stretch pants are taken, buttocks, knee position have compared with screen resilience.
Cotton fiber is soft, and moisture permeability is good, general to be used more as outer wrapping fiber.Cotton fiber conduct is not used
The reason for core filaments, is that its conformality is poor, strength is low, and fold is serious after washing for cloth cover, and abrasion resistance properties are poor.But with people
Pursuing for natural fabric material, the production of cotton covering yarn turn into those skilled in the art's technical problem urgently to be resolved hurrily
One of.
The content of the invention
It is an object of the invention to overcome defect present in prior art, there is provided a kind of air spinning cotton core silk covering yarn
Production technology, the core filaments of covering yarn use cotton yarn made from cotton fiber air spinning, yarn unique style, and skin-friendly is good.
To achieve the above object, the technical scheme is that：A kind of production technology of air spinning cotton core silk covering yarn, its
It is characterised by, comprises the following steps that：
S1：Core filaments must be made through scutching, cotton carding, drafting, air spinning in core silk fiber；
S2：Skin yarn is made through scutching, cotton carding, drafting, rove in outer wrapping fiber；
S3：Cored is made in core-spun yarn device in skin yarn feeding ring spun yarn equipment obtained by core filaments obtained by S1 and S2
Yarn；
S4：Covering yarn passes through the short fine covering yarn of winding procedure finished product air spinning cotton core silk.
Core silk fiber substitutes synthetic filaments of the prior art using air-flow spinning yarn, thick using air-flow spinning yarn style
Rustic, the characteristics of wiriness and the soft personal characteristic of outsourcing cotton fiber, gained yarn form soft outside but hard inside individual style；Gas
It is high to flow the production efficiency of spinning yarn, therefore helps to increase the production efficiency that said flow spins the short fine covering yarn of cotton core silk.In addition,
Cotton fiber possesses natural warping property, and the relative cohesive force between fiber is larger, and cotton fiber and the core filaments cotton fiber of outsourcing mutually entangle
Twine, hook that active force is larger, therefore show as the wearability and excellent, the cloth cover dimensionally stable of strength of yarn.
Preferable technical scheme is that the core filaments import cored by the front roller feeding of spun yarn equipment through active take-off device
Yarn feeding device, skin yarn feed cored silk device after the drawing-off of spinning process.Air spinning yarn is unwind through active, can adjust yarn in good time
The tension force of line, because cotton fiber clears up deficiency in itself, compared with passive unwinding, broken end, yam surface abrasion, filoplume are increased existing
As significantly reducing, ensure that uniform yarn evenness, section rounding and filoplume are few.
In order to ensure that covering yarn resultant yarn has excellent moisture permeability and strength concurrently, preferable technical scheme is air-flow
The fiber number for spinning gained core filaments is 21-25 English branch.Core filaments fiber number can then cause greatly that the cotton fiber in core filaments is expanded because of water suction, and water enters
Enter the unformed area of fibrous inside, core filaments dehydration time length, prolonged vapor action can reduce core filaments and cored silk into
The strength of yarn, also promote the oxidation for causing cellulose, be unfavorable for gloss and the property retention of yarn cloth cover；Conversely, core filaments fiber number
The strength deficiency of small then single yarn, is also easy to the phenomenon to break end occur on spinning process cored station.
Too high rotor speed can cause yarn strength, extension at break, joint success rate all significantly in core filaments production
Decline, end breakage rate also can substantially increase, and then cause production efficiency to decline, and preferable technical scheme is that air spinning produces in S1
The rotating speed of cup is 7900~8100 r/min in core filaments process.Additionally due to core silk fiber separation, twisting are all in free shape
Completed under state, and constantly there is fiber to be slided to along cohesion cell wall during yarn pull-out and twisting is completed and strip a little, can shape
Into more clad fiber, the long then fiber-wall-element model degree of core silk fiber is poor, causes yarn excessively fluffy, core filaments surface it is anti-
Twist direction fibre matting is more, influences the dry uniformity coefficient of bar, so core filaments cotton length can suitably be shorter than outer wrapping fiber length.It is in addition, complete
The covering yarn of cotton is not likely to produce electrostatic in phase mutual friction, and electrostatic is easily played with spandex core-covered silk of the prior art, by contrast,
The environmental requirement when follow-up weaving uses with fabric of air spinning core filaments cotton staple cored silk is low, and wearability is more preferably.
In order to form colour mixture and excessive color effect, cloth cover color and luster is tended to be soft, ensure the color contrast that cloth cover is told somebody what one's real intentions are, it is excellent
The technical scheme of choosing is that one kind in outer wrapping fiber and core silk fiber is colored fibre, and another kind is fine for essential color fiber or white
Dimension.

1.24~1.244, twist factor is 103~110, and Dry Weight per Unit is（7~8）G/10m, ingot speed are 740~760 r/min.Above-mentioned work
The glacing flatness of cotton staple and separating degree are good in skin yarn after the processing of skill condition, are strongly improved after twisting.Twist factor is excessive,
Ingot speed is too fast or drafting multiple is excessive can cause filoplume to increase, and yarn strength declines, and ultimately results in yarn quality decline.
Preferable technical scheme is that core filaments weight accounts for the 55~70% of air spinning core filaments cotton staple cored silk resultant yarn total amount, outside
Bag fiber is colored fibre.Core filaments for white or essential color fiber, outer wrapping fiber be colored fibre then, cored silk of the prior art
Skin yarn weight is more than core filaments weight, and main purpose is to be formed close uniform and has certain thickness cladding, and such scheme
The heterochromatic cored silk core filaments of SMIS skin are gleamingly exposed to the surface of yarn body, and core filaments strength determines the strong of cored silk resultant yarn
Power, the resultant yarn of identical number, because the cross-section fibers radical of core filaments is more, due to larger cohesive force between fiber be present, therefore with
Synthetic filaments cored silk is compared, and air spinning core filaments cotton staple cored silk fracture strength is larger.
In order to ensure that skin yarn is evenly coated at core filaments periphery, make outer wrapping fiber have suitable radial pressure and with core filaments cotton
Cohesive force between fiber, resultant yarn filoplume is few, and preferable technical scheme is that the spinning process technological parameter of skin yarn is：Total draft
Multiple 33~40, back zone drafting multiple are 1~1.4, and ingot speed is 13800~14200 r/min, and the twist is 400~440TPM, sieve
It is respectively 50~55mm and 52~56mm to draw centre-to-centre spacing, 7~8mm of spacing block.
