Description

Aramid composite yarn for hunting wear having high strength, elasticity and soundlessness}

The present invention relates to an aramid composite yarn for hunting clothing that is worn during hunting, and more particularly, it can be comfortably worn without tearing branches or thorns even in active movement, and hunting animals approach it because it does not generate noise during movement. It relates to an aramid composite yarn that can be used as a material for hunting clothing with excellent strength, elasticity, and noise reduction so as not to recognize it.

As the living standards of modern people improve and leisure time increases, the number of enthusiasts who enjoy hunting is increasing.

Among these hunting products, hunting clothes are essential to protect the body of hunting lovers who move a lot in rough terrain such as mountainous areas. As conventional hunting clothing is made of general fibers such as nylon and polyester, there is a problem in that it is often torn or damaged by branches, thorns, or a hunting weapon, such as a knife.

In order to improve this, "a method for manufacturing a fabric for hunting clothes" of Korean Patent Application Laid-Open No. 10-2017-0024760 has been proposed. Improving puncture resistance and abrasion resistance.

However, in addition to the physical properties such as strength and abrasion resistance, hunting clothing requires elasticity so that it can be worn comfortably even with intense movement. Also, for hunting wild animals with sensitive hearing, low sensitivity of the fabric fricative sound generated by the movement of the wearer need.

Republic of Korea Patent Publication No. 10-2017-0024760 (Manufacturing method of fabric for hunting clothing)

Accordingly, an object of the present invention is to provide an aramid composite yarn for manufacturing hunting clothing that can reduce noise generation due to friction between fabrics during movement, as well as strength and elasticity.

In order to solve the above technical problems, the present invention provides an aramid composite yarn for hunting clothing which is formed by a covering yarn that wraps the outer surface of the examination, which is a stretch yarn, with an effect yarn, and an aramid yarn having a wool formed on the surface of the covering yarn.

In addition, in the present invention, the single yarn of 30 ~ 80's of the amarid spun yarn is ply-twisted, and the covering yarn and the aramid spun yarn are ply-twisted at 200-500 TM in a direction different from the ply-twisting direction of the aramid spun yarn.

In addition, in the present invention, the effect yarn is formed of a nylon yarn wound at 200 to 500 TM on the outer surface of the core.

In addition, in the present invention, the aramid spun yarn has a color expression of the original yarn 5 ~ 10 g / d strength and 3 ~ 5% elongation.

According to the present invention, it has excellent strength and is not torn from branches or thorn bushes when weaving as hunting clothing, and has excellent elasticity and elastic recovery to provide a comfortable fit even when wearing it, as well as moue formed on the surface of aramid spun yarn It is possible to reduce frictional force and thus reduce noise during movement.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

This embodiment is provided to more completely explain the present invention to those with average knowledge in the art, and the shape of elements in the drawings, the size of elements, the spacing between elements, etc. are to emphasize a clearer description may be exaggerated or reduced for

In addition, in the description of the embodiment, if a component is described as being “formed”, “included”, “coupled”, or “fixed” to another component, it is directly formed in the other component, It may be included, coupled, or fixed, but it will be understood that other components may be present in between.

In addition, when it is determined that the technical features of the present invention may be unnecessarily obscured as it is already obvious to a person skilled in the art, such as a known function or a known configuration related in principle in describing the embodiment, the detailed description thereof A description will be omitted.

1 is a front view showing the structure of the aramid composite yarn 100 for hunting clothing according to the present invention. Referring to this, the aramid composite yarn 100 according to the present invention is composed of a screening 11 and an effect yarn 12. The covering yarn 10 and the aramid yarn 20 are ply-twisted.

2 is a view showing a covering yarn 10 according to the present invention. The covering yarn 10 is made by covering the outer surface of the core 11, which is an elastic yarn, with a nylon yarn having excellent strength and an effect yarn 12. As shown in FIG. In this case, the elastic yarn used as the core layer 11 may include polyurethane, SBS, SBR, PDMS, or silicone-based rubber material. Among them, polyurethane having high elasticity, low elastic modulus, and high elastic recovery rate is preferable. Do. The elastic yarn is preferably formed with a fineness of 30 to 60 denier so that durability and elasticity can be expressed.

The effect yarn 12 may be a nylon original yarn to express a unique color, and even if the core 11 is stretched, 200~ It is preferably wound with 500 TM.

The aramid spun yarn 20 is plied to the covering yarn 10 having excellent elasticity and elastic recovery to improve strength and low noise characteristics. The aramid spun yarn 20 is manufactured by mixing short aramid fibers containing pigments or dyes to express beautiful colors, carding, carding, spinning, and softening processes.

To this end, first, by passing the short aramid fibers through a carding roller equipped with a needle needle and combing (carding), the aggregated short fibers are separated one by one, while foreign substances in the short fibers are removed. At this time, the needle needle of the carding roller that separates the short fibers is disposed to be inclined in the transport direction of the short fibers to effectively remove foreign matters in the short fibers.

At this time, it is preferable to spray and mix the softening agent so that these short fibers do not adhere to the needle needle or the carding roller due to static electricity. As the softening agent, 0.1 to 5% by weight of a silicone-based softener such as silicone emulsion, self-emulsifying silicone, etc., 95 to 99.9% by weight of water, or 0.1 to 5% by weight of a nonionic softening agent such as polyvinyl alcohol emulsion, water 95 A nonionic softening agent consisting of ∼99.9% by weight may be used.

As such, the aramid slivers arranged in one direction are ply-bonded with other aramid slivers manufactured in the same process, and stretched and twisted to produce an aramid spun yarn 20 having a fineness of 30 to 80's. At this time, if the fineness of the aramid spun yarn 20 is less than 30's, weaving is difficult, and if it exceeds 80's, the weight is heavy and the wearability is not good. The aramid spun yarn 20 produced in this way has a strength of 5 to 10 g/d and an elongation of 3 to 5%.

3 is a photograph of the aramid spun yarn 20 according to the present invention, on the surface of which a mou 21 is formed so as to reduce the frictional force of the surface of the fabric during movement, and with the covering yarn 10 so as not to be loosened by external force. It is ply-twisted in a direction different from the ply-twisting direction, for example, the aramid spun yarn 20 ply-twisted with each other in the S-twisting direction may be ply-twisted with the covering yarn 10 in the Z-twisting direction. At this time, the aramid spun yarn 20 and the covering yarn 10 are twisted by 200 to 500 TM.

The manufactured aramid composite yarn 100 has excellent strength, so it is not torn from branches or thorns when weaving as hunting clothing, and has excellent elasticity and elastic recovery, so it not only provides a comfortable fit for movement when wearing, but also aramid spun yarn (20) It is possible to reduce frictional force by the mou formed on the surface, thereby reducing noise during movement.

<Example>

A covering yarn was prepared in which 100 denier nylon 66 was wound with 500 TM in the Z direction as an effect yarn for 40 denier polyurethane screening. And, an aramid spun yarn obtained by plying two strands of para-aramid spun yarn having a fineness of 50's at 400 TM in the S direction direction was plied with a covering yarn at 350 TM in the Z direction direction to prepare an aramid composite yarn. And, the aramid composite yarn prepared in this way and nylon 66 were arranged as weft yarns in a ratio of 1: 6, and nylon 66 was woven with a dobby tissue at a warp to prepare a hunting clothing fabric as shown in FIG. 3, and the properties are as follows.
