Technical field

The present invention relates to textile yarn technical fields, the especially a kind of preparation of the high-elastic core-spun composite yarn of half worsted Method.

Background technique

With the improvement of people's life quality, consumer is higher and higher to the comfort requirement of clothes.Traditional half is spinning Wool yarn is faced with the problems such as strength is low, and resilience is insufficient, and filoplume is big.

Summary of the invention

The purpose of the present invention is to solve the deficiencies of the above technologies and provide, and a kind of high-elastic cored of half worsted is compound The preparation method of yarn can improve weaving strength, resilience and the bar evenness of half worsted product.

In order to achieve the above object, the preparation side of the high-elastic core-spun composite yarn of half worsted of one kind designed by the present invention Method: specifically comprise the following steps:

The first step, the selection of raw material: 90S Basolan Australia hair and polyester filament, wherein 90S Basolan Australia hair 70-80%, 30D/24F Polyester filament 20-30%, total proportion of two kinds of raw materials is 100%, and said ratio is mass ratio；

Polyester filament rewinding: second step carries out winder to polyester filament using reeling equipment, prepares for cored production；

The preparation of pure wool slubbing: third step by 90S Basolan Australia hair, successively passes through dyeing process, wool blending step, carding work Sequence, mixing in doubling step, Roving Frames are prepared into wool slubbing；

4th step, the preparation of core-spun composite yarn: pure wool slubbing prepared by the polyester filament of second step rewinding and third step High-elastic core-spun composite yarn is prepared by spinning process, winding procedure, doubling process, double twisting process.

As optimization, wherein second step, polyester filament rewinding: using reeling equipment by polyester filament network in diameter 7.5CM, On the small paper tube of the hard of width 5.5CM, fixed length 30KM.

Wherein third step, the preparation of pure wool slubbing: addition is by water and crude oil DH-601 and antistatic agent in wool blending step The mixed liquor that DK-103 is mixed, the dosage for neutralizing crude oil DH-601 are prepared by the 1-1.2% of Basolan Australia gross weight amount, are resisted The dosage of electrostatic agent DK-103 is prepared by the 0.6-0.8% of Basolan Australia gross weight amount, and the dosage of water is by the hair actual measurement resurgence of Basolan Australia Reach 20-22% preparation；It is combed when carding process using roller and clearer card.Carding selects roller and clearer card when handling Soft combing is carried out, cooperates dilute tooth, wide-angle, the Bearded-needle knitted cloth of model AC2815*01865P, while combing sufficient item Lower cylinder revolving speed is used under part, revolving speed is at 200-250 revs/min, to reduce fibre damage, reduces carded sliver short fiber content.

Wherein the 4th step, the preparation of core-spun composite yarn: when spinning process processing, cored dress is spun in installation on spinning frame Set: the synchronized iron rod that polyester filament is driven by two spinning frame front rollers is as unwinding roller, through being mounted on above front leather roller Godet roller is fed by front roller, and front roller and unwinding roller speed limit ratio are adjusted to 1.06-1.1；Wherein spin cored device such as Fig. 1 It is shown, including flyer bobbin, long fiber tube, unwinding roller, traveller, godet roller, rear roller, middle roller, front roller.Rove is from rove Pipe output, sequentially enters rear roller, middle roller and front roller, polyester filament is exported from long fiber tube, after traveller, godet roller Into front roller.Rove is crushed into front roller at middle roller, and polyester filament also enters front roller simultaneously, and is located at and flattens Rove center at, polyester filament is coated on inside in rove Recovery Process after front roller output by the two.

When doubling process, the processing of double twisting process, twisted using two strands of single thread and after closing, double twisting institute's amount of twist is according to knitting piece water Skew of weft situation after washing is adjusted.If fabric S orientation skew of weft every 5^o10 twists/m are reduced, fabric Z orientation skew of weft every 5 on the contrary^oIncrease Add 10 twists/m.

Strand after double twisting process is carried out shaping by yarn steaming technique, and wherein yarn steaming technique is first circulation: 50 DEG C, 20min, -60kPa；Second circulation: 60 DEG C, 25min, -50kPa.

The obtained a kind of preparation method of the high-elastic core-spun composite yarn of half worsted of the present invention: by using polyester fibre Dimension and cored technology have the weaving strength and resilience for improving half worsted product, the effect of bar evenness；It obtains Complex yarn has the characteristics that high-tenacity, high rebound, item is dry uniformly, filoplume is few.
