Description

China hemp fiber blending colored spun yarn

Technical Field

The utility model relates to a textile technology, more specifically say, it relates to a china-hemp fibre blending colored spun yarn.

Background

The cotton fiber and the hemp fiber are natural fibers, and have the advantages of no pollution, safety, good affinity to human bodies, comfort in wearing, moisture absorption, air permeability, wide sources, reproducibility, easy biodegradation and the like, so that the cotton fiber and the hemp fiber are popular with people.

An elastic core-spun yarn disclosed in chinese patent publication No. CN210796770U has the technical essential that: through setting up the sandwich layer, make this covering yarn when receiving external force and dragging, can adapt to through the better elasticity that the sandwich layer itself possessed, avoid this covering yarn to drag the condition of breaking occur after the longer length, and first enhancement yarn, the syntropy winding of second enhancement yarn and third enhancement yarn is in the sandwich layer outside, follow the sandwich layer and together be dragged, because it is the heliciform, can suitably take place elastic deformation and adapt to the pulling force, and this covering yarn can be through the sandwich layer, first enhancement yarn, second enhancement yarn and third enhancement yarn share the pulling force, make this covering yarn need bigger pulling force when being pulled, through setting up the connecting wire, when making the covering yarn be dragged, the connecting wire can be to first enhancement yarn, second enhancement yarn and third enhancement yarn play and drag the effect, avoid the three to take place to break away from, increase the structural strength of covering yarn, also can share the pulling force.

The problem of covering yarn can't bear great pulling force in the use has been solved in the above-mentioned scheme, very easily broken by the pulling, lack better tensile strength, but through adopting first enhancement yarn, second enhancement yarn and third enhancement yarn to form the winding section at the surface of covering yarn, but because first enhancement yarn, second enhancement yarn and third enhancement yarn syntropy winding structure (as its description attached drawing show) for this elasticity covering yarn is when being used for weaving, because first enhancement yarn, second enhancement yarn and third enhancement yarn provide the moment of torsion along same direction, make the yarn appear when weaving beating the book, the winding forms the condition of thread section, influence follow-up fabrics and weave.

Therefore, a new solution is needed to solve this problem.

SUMMERY OF THE UTILITY MODEL

The utility model discloses further set up to: the core yarn is formed by twisting a plurality of strands of combed cotton fibers, and the twist of the core yarn is greater than that of the twisted yarn.

The utility model discloses further set up to: the twisted yarn is formed by twisting a plurality of strands of hemp cellulose, and the thickness of the twisted yarn is larger than that of the core yarn.

The utility model discloses further set up to: the twist of the twisted yarn is 80 twist, the twist of the core yarn is 120 twist, and the pre-tension of the core yarn and the twisted yarn is 0.25 +/-0.05 cN/tex.

The utility model discloses further set up to: the core yarns and the adjacent twisted yarns wound outside the core yarns are arranged in a reverse twisting direction.

To sum up, the utility model discloses following beneficial effect has:

the scheme is characterized in that a plurality of colored yarn units are plied, wherein the colored yarn units are made of core yarns and twisted yarns, the twisted yarns arranged outside the core yarns are gradually wound from the core yarns to the circumference to form core-spun yarns, and because the yarn cores and the adjacent twisted yarns are arranged in opposite directions, the twisting directions between the two mutually adjacent twisted yarns can be arranged in opposite directions, the strength and the anti-loosening performance of the yarns can be improved, the generation of hairiness is reduced, meanwhile, the twisting directions arranged in opposite directions can offset the torque, and the problem that the existing core-spun yarns are easy to wind and knot in the spinning process to form yarn knots is solved.

In the figure: 1. a core yarn; 2. and (4) twisting the yarns.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

a China-hemp fiber blending colored spun yarn is formed by plying colored yarn units, as shown in figure 1, each colored yarn unit comprises a core yarn 1 and a twisted yarn 2 wrapping the core yarn 1, the twisted yarn 2 is an even number of strands, the winding directions of at least two twisted yarns 2 are arranged in a reverse mode, the twisted yarn 2 is an even number of strands and is wound outside a yarn core in a reverse mode, when the twisted yarn 2 is wound outside the core yarn 1, torque force formed in the twisting direction can be mutually counteracted, the situation that yarn knots appear due to winding and twisting easily caused by fibers or yarns of an outer winding part of the core yarn 1 is eliminated, meanwhile, a plurality of cationic groups are formed on the surfaces of the core yarn 1 and the twisted yarn 2 through cationic modification finishing of the core yarn 1 and the twisted yarn 2, the cationic groups are formed on the surfaces of the core yarn 1 and the twisted yarn 2 through cationic modification finishing, and the dyeing rate of dyes can be improved when the colored yarn units are dyed.

The core yarn 1 is formed by twisting a plurality of strands of combed cotton fibers, the twisted yarn 2 is formed by twisting a plurality of strands of hemp cellulose, the twist of the core yarn 1 is greater than that of the twisted yarn 2, the thickness of the twisted yarn 2 is greater than that of the core yarn 1, specifically, the twist of the twisted yarn 2 is 80 twist, the twist of the core yarn 1 is 120 twist, the pre-tension of the core yarn 1 and the pre-tension of the twisted yarn 2 are both 0.25 +/-0.05 cN/tex, the twist of the core yarn 1 is greater than that of the twisted yarn 2, the twisted yarn 2 is favorably coated outside the core yarn 1, the core yarn 2 has a combing effect, hairiness on the surface of a colored yarn unit is reduced, the thickness of the twisted yarn 2 is greater, the twist difference between the twisted yarn 2 and the core yarn 1 can be increased, the integral twist of the yarn is improved, and the anti-loosening performance of the yarn is further improved.

Specifically, in the embodiment, the core yarn 1 is formed by twisting combed cotton fibers in the S twisting direction, and the twisting yarns 2 are respectively S-twisted and Z-twisted yarns, firstly the Z-twisted core yarn 2 is wound outside the S-twisted core yarn 1, and then the S-twisted twisting yarn 2 is wound outside the Z-twisted twisting core yarn 2.

Through being reverse twisting's mode in proper order in turn, can improve the tensile strength of look yarn unit, can provide reverse structure simultaneously, make look yarn unit twist with fingers 2 that receive at each section department on its length direction and cause the moment of torsion power to balance, thereby reach and have good antitorque effect, and twist with fingers 2 and choose the fibrilia material for use, can possess the moisture absorption through the fibrilia and switch on, the good characteristics of gas permeability, help improving the mediation of skin surface sweat, the condition of sticking with sweat is difficult to appear.

And after the dyed yarn unit is spun into yarns through modification operation, the yarns can be dip-dyed in a dye dipping mode, so that dyed yarns rich in various colors are obtained, various weaving requirements are met, and the subsequent step of finishing fabrics is shortened.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the fan belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
