Abstract

The invention discloses a yarn and belongs to the spinning field. The yarn comprises a core thread (1) and a plurality of covering threads (2); the core thread (1) comprises an outer thread zone (3) and an inner thread zone (4); the covering threads (2) are crocheted on the outer thread zone (3). Compared with the prior art, the yarn has beneficial effects that the special multi-gap structure is formed through crocheting, so that the yarn has large air storage amount, compared with the yarn with the same quality, the warm keeping effect is better, compared with the fiber product with the same warm keeping level, the weight of the fiber product made of the yarn is lighter; when cleaning, the fiber is expanded when meeting the water, the covering threads are loosened, at macro level, the yarn volume is increased, the core thread is exposed, and accordingly the cleaning is facilitated.

Description

A kind of yarn

Technical field

The invention belongs to field of textiles, relate to a kind of yarn.

Background technology

In the middle of currently available technology, the primary structure form of yarn is mainly divided into following several: 1, and multiply fiber is spiral twisted form each other; 2, by a thicker center line, as middle bone, other fine rules are spirally wound on center line.Above yarn texture shortcoming mainly comprises following three: 1,, because space in line is few, therefore warming coefficient is low, and warming effect is general; 2,, aspect cleaning, in the time that spot is infiltrated yarn inside compared with depths, yarn cleans very difficult; 3, yarn product weight is often heavier, affects comfort level, and dresses for a long time, cleans very easy distortion, affects attractive in appearance.

Summary of the invention

The object of the invention is to, provide that a kind of quality is light, easy cleaning, yarn that warming coefficient is high.

In order to achieve the above object, the invention provides a kind of yarn and comprise middle heart yearn and many covering yarns; Described middle heart yearn comprises outer layer line district and interior layer line district; Described covering yarn crocheting is in described outer layer line district.

Middle heart yearn, as the skeleton of yarn, has determined the main character feature of yarn.Covering yarn is attached on middle heart yearn and forms clad, and clad is sense of touch layer, directly affects the sense of touch of yarn.Adopt many covering yarns to be attached on middle heart yearn by the form of crocheting, its main purpose is: 1, by crocheting, form special multiple-void structure, make to possess in yarn the memory space of more air, thereby the in the situation that of equal in quality, obtain more superior warming effect, or the in the situation that of identical warming grade, obtain the fibre of lightweight more; 2, in the time cleaning, fiber enters water and expands, and covering yarn is lax, shows yarn volume and become large in macroscopic view, and middle heart yearn is exposed, becomes very easy thereby make to clean.

The thick ratio of line of described middle heart yearn and covering yarn is 5:1 ~ 30:1.Preferably, the thick ratio of line of described middle heart yearn and covering yarn is 10:1.The diameter proportion of heart yearn and covering yarn in suitably adjusting, can obtain different yarn features, such as: 1, when keeping the rigid nature of yarn, also to ensure the smooth softness of yarn sense of touch, adopt heart yearn in the harder fiber making of quality, the fiber that quality is softer, diameter is relatively thick is made covering yarn; 2,, in the time that needs keep yarn to have good pliability, can adopt the middle heart yearn with high tenacity to coordinate the thin matter covering yarn structure of the more and compact configuration of quantity.

Close-packed arrays between described each covering yarn.Adopt close-packed arrays structural design, not only can increase the vision quality sensation of yarn, strengthen yarn luster degree, and facilitate yarn to process again, as colouring, antistatic, flame treatment etc.

Gap arrangement between described each covering yarn.Adopt gap arrangement structural design, can make more easy cleaning of yarn, and glossiness is low, be difficult for causing reflective.

Certainly should be by suitably adjusting the spacing between each covering yarn, mutual undue extruding or excesssive gap while avoiding making covering yarn to arrange.Undue extruding easily reduces the air memory space in yarn, reduces warmth retention property, reduces softness of yarn; Excesssive gap can reduce the warmth retention property of yarn equally, and covering yarn is easily subject to the external force company of twining even each other that deforms.

Therefore known, by the quantity of suitable adjustment covering yarn and the diameter proportion of covering yarn and middle heart yearn, can obtain the different fibre of performance.

Described middle heart yearn is made up of multiply fiber spiral twisted.Adopt multiply fiber milling structure, can make SMIS line obtain better fibre property, comprise elasticity, toughness etc., and can realize the possibility that adopts the technique of heart yearn in the making of multiply variety classes fiber mixing twisted.Certainly can also adopt single-stranded fiber structural design, so design can facilitate technological design, and simplification of flowsheet lowers defect rate, enhances productivity.

Described middle heart yearn adopts high-tension fiber to be made.Preferably, described high-tension fiber is high-tension silk flosssilk wadding fiber, and described high-tension silk flosssilk wadding fiber is made up of 45% cotton, 47% regenerated fiber and 8% Lycra.The characteristic of middle heart yearn has determined the characteristic that yarn is main, as intensity, toughness, rigidity etc., adopts as above design, can make finished product yarn obtain high-elastic effect.

Described covering yarn is made by azelon.Preferably, described azelon is complex type egg white fiber, and described complex type egg white fiber is made up of 45% combed cotton, 47% pupa protein fiber and 8% Lycra.The characteristic of covering yarn has determined the secondary characteristic of yarn, as sense of touch, absorbing sweat effect, visual impression etc., adopts as above design, not only can make finished product yarn have good submissive sense of touch, and vision is soft, glossy.

Compared with prior art, beneficial effect of the present invention is:

Yarn qualities of the present invention gentlier, more easy cleaning, warming coefficient is higher, fibre property is more easy to control.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, yarn comprises the middle heart yearn 1 be made up of three strands of fiber spiral twisteds and many crochetings covering yarn 2 on middle heart yearn 1, and middle heart yearn 1 is divided into outer layer line district 3 and interior layer line district 4, in covering yarn 2 crochetings and outer layer line district 3.The diameter of covering yarn 2 is 1/10th of middle heart yearn 1 diameter, and gap arrangement between each covering yarn 2 can be also close-packed arrays.Middle heart yearn 1 three strands of fibers used are high-tension silk flosssilk wadding fiber and make, and this high-tension silk flosssilk wadding fiber is made up of 45% cotton, 47% regenerated fiber and 8% Lycra.Covering yarn 2 is made for complex type egg white fiber, and this complex type egg white fiber is made up of 45% combed cotton, 47% pupa protein fiber and 8% Lycra.

Can find out by Fig. 3 and Fig. 4, the distribution of covering yarn 2 on middle heart yearn 1 can be lineal layout, can also be Spiral distribution.
