Specific embodiment

Below in conjunction with the subordinate list content in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear Chu is fully described by, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts all Other embodiments shall fall within the protection scope of the present invention.

Blended using Kapp dragon copper ion anti-bacterial fibre and the ultra-fine regenerated celulose fibre of Mai Nuofen, Kapp dragon copper ion is anti- Bacterium fiber has strength and lasting antibacterial bacteriostatic, odor eliminating function, and it is that can reach excellent antibacterial effect that content, which is 5%,； The ultra-fine regenerated celulose fibre good hygroscopicity of Mai Nuofen, softness, gloss are graceful, using mixed yarn product made of both fibers With durable antibiotic, and soft comfortable, table Ganfeng are expired, clean mark.

Kapp dragon copper ion fiber is a kind of hygroscopicity acrylic fibers rich in copper ion, is in magma polymerization stage, with connecing Branch copolymerization technique has grafted organic brass chain and high hydrophilic radical on acrylic fibers macromolecule side chain respectively, then through wet spinning technology Made of New Acrylic.The copper ion of Kapp dragon copper ion fiber is present in fiber firmlyly and non-freely, thus has aobvious Write and lasting antibacterial bacteriostatic, eliminate peculiar smell, self-cleaning healthy function, antibacterial effect to fungi it is further preferred that.The public affairs of the fiber are returned surely Damp rate is up to 8%, significantly larger than common acrylic fibers, thus the textile prepared has excellent hygroscopicity and comfort.

The fiber shows that sterilizing rate is to the antibacterial Indexs measure of staphylococcus aureus, Candida albicans, Escherichia coli 99%, reach the highest AAA grade standard of national textile industry；In practical applications, only need to contain 5% copper ion fiber and its His general fibre is blended, and after 50 times are washed repeatedly, mixed yarn still maintains excellent antibiotic property.

The ultra-fine regenerated celulose fibre of Mai Nuofen is one kind of ultra-fine regenerated celulose fibre, is made of pure natural raw material, It is biodegradable；Its fineness is 0.5dtex, can spin high-count yarn, and the comfortable softness of made fabric touch, color are bright It is beautiful, it is the desirable feedstock of high-quality clothes and home textile product.But the fibre strength is lower, mixed with Kapp dragon copper ion anti-bacterial fibre After spinning, antibacterial functions can be not only obtained, moreover it is possible to improve yarn strength.

1, mixed processes

Kapp dragon copper ion anti-bacterial fibre and the ultra-fine regenerated celulose fibre of Mai Nuofen are put into according to the ratio of 5:95 Disc bale plucker should accomplish " interleaved, uniformity " when disk is arranged and wrapped, and guarantee that various raw material height are consistent, gap is filled out It is full.Because Kapp dragon copper ion anti-bacterial fibre ratio is low, to guarantee to be uniformly mixed, double grasp modes are taken, that is, uses and is packaged after grabbing Machine breaks into hard-pressed bale, and then investment disc bale plucker is grabbed again.Which other mixed cotton mode recruitments that compare are few, production Efficiency is higher.

2, shredding process

Since the ultra-fine regenerated celulose fibre strength of Mai Nuofen is lower, hygroscopicity is strong, raw material is close, shredding process should be followed The principle of " short route, low velocity, few strike ", is reduced as far as fibre damage, the kink of fiber is avoided to crumple.It should reduce each The speed of hired roughneck, prevents excessive velocities from fiber is broken into synnema.In order to which two kinds of fibers are mixed evenly, to avoid since fiber is excessive Coma caused by rolling.Fibre damage in order to prevent is production technology original with " more pines, less beat, beaten with comb generation, antiwind " Then, cotton rolling weight should be grasped gently partially, grab cotton hired roughneck, the speed of kirschner beater needs to reduce, and wind speed improves, and gauge is appropriate at strike Adjustment increases, in order to avoid damage fiber, increases short flannel and cotton knot, volume is sticked when coiled in order to prevent, can choose and several viscose glues are added Rove.

3, the superiority and inferiority of carding step will have a direct impact on formation yarn nep, so to take into account combing and reduce two side of fibre damage Face.With trocar cloth and optimize technique according to the performance characteristics of two kinds of raw materials, using flexible recombing technique, to control the carded sliver Cotton knot and short flannel.The ultra-fine regenerated celulose fibre of Mai Nuofen is very thin, and single fiber strength is relatively small；Kapp dragon copper ion anti-bacterial fibre It is strongly slightly higher, but because content is very low, so after two kinds of fiber mixing still based on the ultra-fine regenerated celulose fibre of Mai Nuofen, due to The fibre property and cotton fiber performance are close, and cotton can be used to match trocar cloth.Licker-in speed should be suitably reduced, fiber damage is reduced Wound；Cover board is suitably tightened with cylinder interval distance, strengthens the combing effect to fiber；Using lower cover plate speed, cover board is reduced Flower；The moderate grasp of cotton net tension is dry to avoid carded sliver item is influenced；Pay attention to observing cotton net sharpness, accomplishes no clouding and broken hole, weight Point controls sliver impurity number.

4, mixing in doubling step

In order to be mixed evenly sliver, color is consistent, and is further ensured that blending ratio, at the same guarantee fiber stretch with it is ripe The item of item is dry uniformly, takes the technological principle of " jogging speed, again pressurization, big gauge, reasonable drawing-off ", takes three draftings, item The quantitative partially light grasp of son, per pass number of doubling is 8, and extreme trace drafting uses the drawing frame with evereven, can be made each Fiber blend is reduced than accurately, guaranteeing the color homogeneity of strip, and the extended parallelization of fiber can be improved because of hooked fibre The cotton knot colluded with and formed.Simultaneously back area draft is bigger than normal for head, and simultaneously back area draft is smaller at end, to improve the uniformity of strip.Drafting work Phenomena such as sequence should reduce stop frequency to the greatest extent, and cleaning will handle properly, and prevent unsmooth channel, wounded obstruction.

5, Roving Frames

Process of roving takes the technique of " light quantitative, small back area draft, reduces unexpected elongation at slightly larger roving twist factor " former Then.The ultra-fine regenerated celulose fibre cohesive force of Mai Nuofen is poor, and roving twist factor will reasonably select, bigger than normal to easily cause spun yarn drafting not It opens, rove less than normal is easy to produce unexpected elongation.Due to the double-colored yarn of AB be two different colours rove on spinning frame simultaneously Feeding spins, and regular roving feeding should be controlled gently partially, choose rove horn mouth, avoid rove excessively fluffy.Adjust spinning Tension, it is ensured that the tension of large, medium and small yarn and front and rear row yarn is almost the same, to reduce rove weight unevenness, reduce it is long slightly and Long spun yarn defect.Under the premise of spun yarn not harmful drafting, roving twist factor grasp bigger than normal as far as possible, to increase the strength of rove, it is ensured that Spinning process rove is smoothly unwound, and reduces the bad caused details of unwinding, or even break rove phenomenon.

6, spinning process

Spinning process is carried out in SEILE textile equipment, passes through double horn mouth respectively for A, B two, while feeding drawing-off Area.In order to prevent because two root thickness yarns are fed, drafting force is excessive to be there is drawing-off and does not open phenomenon, spun yarn using " again pressurization, low velocity, The technological principle of big back zone gauge, small back area draft ".The selection less than normal of spun yarn back area draft increases fibre cohesion, reel cage pressure It lays particular stress on and grasps, select the reasonable duplex horn mouth of spacing, spacing will be adapted with the suitable for reading of shape tube air draught slot, while be ensured Spun yarn machinery is in good condition.It should reinforce touring in operation, prevent single-strand spun phenomenon, influence product quality.

Spinning process prevents color fibre pollution from mainly starting with from the following: spinning board first must be from adjacent different product Kind board is completely isolated, prevents color fibre to be mixed into other kinds and generates pollution；Secondly resultant yarn is it is noted that uneven twist, prevents uneven twist The color difference of generation prevents spun yarn or rove repiece yarn wrong；Finally after spinning it is noted that carry out ending cleaning, Necessary anti-pollution measure is taken, spun yarn bellows flower will be recycled individually.

7, winding procedure

Winding procedure requires speed relatively low, and tension is less than normal, to reduce the growth rate of filoplume, reduces broken end number, uses The technological principle of " small tension receiving coil, low velocity ".Yarn path smooth clean is kept, prevents item is dry from deteriorating, filoplume increases.It rationally designs Splicer parameter, controls joint quality, and reasonable set electronic clearing parameter especially reinforces details excision, prevents sub-thread from flowing into Finished product.Reinforce electronic yarn clearer maintenance and cleaning, reduce leakage cut, accidentally cut, cut-in without ball phenomenon.
