Background

Polypropylene, PP for short, is a colorless, odorless, nontoxic and semitransparent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent performance, and is colorless translucent thermoplastic light general-purpose plastic. The polypropylene has chemical resistance, heat resistance, electrical insulation, high-strength mechanical property, good high-wear-resistance processing property and the like, so that the polypropylene can be rapidly and widely developed and applied in a plurality of fields such as machinery, automobiles, electronic and electric appliances, buildings, textiles, packaging, agriculture, forestry, fishery, food industry and the like since the coming out.

With the development of economy, the polypropylene yarn is gradually applied to the social aspect, and the existing polypropylene yarn is difficult to meet the requirement on the support property.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provide a stiff and smooth warm polypropylene yarn.

The stiff and smooth warm-keeping polypropylene yarn comprises a yarn core, wherein a plurality of protrusions are arranged on the yarn core, one ends of the protrusions are fixedly connected with the yarn core, the cross section of the other ends of the protrusions is gradually enlarged and provided with arc-shaped end faces, and arc-shaped depressions are formed in the middle of the protrusions.

Through adopting above-mentioned technical scheme, the arch can play and support the yarn core to increase the holistic support performance of yarn core, make after the design yarn core when meetting external force, the arch can play the effect of support, thereby reach and prevent that the yarn core warp, let the polypropylene fibre yarn have better stiff and smooth sense, and make the air difficult flow after getting into sunkenly through the arc is sunken, reach the effect that increases thermal insulation performance.

Preferably, one end of the convex arc-shaped end face is provided with a supporting yarn used for connecting with the other convex arc-shaped end face, and the supporting yarn is connected with the yarn core through a protrusion to form a warm-keeping cavity.

Through adopting above-mentioned technical scheme, the support yarn is connected the arch for protruding holistic support performance promotes, and through the cold-proof chamber that support yarn and bellied be connected and form, make more air locked in the yarn, thereby increase the holistic warmth retention property of yarn.

Preferably, supplementary yarns for preventing the support yarns from deforming are arranged in the warm keeping cavities.

Through adopting above-mentioned technical scheme, supply the yarn between yarn core and supporting yarn, will support yarn surface support to avoid supporting yarn to warp and lead to holistic support nature to reduce.

Preferably, the support yarns are on the same diameter circle as the furthest point of the projection from the yarn core.

Through adopting above-mentioned technical scheme, the farthest point that the yarn core was kept away from to support yarn and arch is on leading to the circle of diameter for the holistic diameter of yarn keeps unanimous, reduces the roughness on yarn surface simultaneously, makes the yarn more smooth.

Preferably, a hollow cavity is arranged in the middle of the yarn core.

By adopting the technical scheme, the hollow cavity can store more air, so that the overall heat-insulating property of the yarn is improved.

Preferably, the yarn core, the supporting yarn and the supplementary yarn are integrally molded and sprayed by polypropylene.

By adopting the technical scheme, the polypropylene is integrally formed and sprayed, so that the integral strength of the yarn is improved, the stress is better dispersed, and the situation that connecting points are easy to separate is avoided.

Compared with the prior art, the utility model has the beneficial effects that: the yarn core is supported through the protrusions and the supporting yarns, so that when the yarns are stressed laterally, the supporting yarns and the protrusions can share the stress, the stress on the yarn core is reduced, the yarn core is prevented from deforming, and meanwhile, the better air lock is enabled to be arranged inside the yarns through the hollow cavities and the warm keeping cavities of the yarns, so that the better warm keeping performance is achieved.

Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a stiff and smooth cold-proof polypropylene fiber yarn, including yarn core 1, be provided with a plurality of archs 2 on the

yarn core

1, 2 protruding one end and 1 fixed connection of yarn core, other end cross-section grow gradually and be provided with the arc terminal surface, and 2 protruding middle parts are formed with the arc sunken, 2 protruding arc terminal surface one end is provided with the support yarn 3 that is used for another 2 protruding arc terminal surfaces to be connected, support yarn 3 is connected with yarn core 1 through protruding 2 and is formed with cold-proof chamber 4, be provided with the supplementary yarn 5 that is used for preventing support yarn 3 deformation in the cold-proof chamber 4.

When the product is used, the product is used for filling the fabric, so that the fabric achieves a fluffy effect, when the fabric is extruded, the extruding force is transmitted to the yarn, the supporting yarn 3 or the protrusion 2 supports the external force and is transmitted to the yarn core 1 through the protrusion 2, the three protrusions 2 and the supporting yarn 3 form a triangular structure, the supporting force is more stable when the external force is dispersed through the stability of the triangle, the yarn core 1 is prevented from deforming after the fabric is extruded, the fabric is prevented from being crushed and cannot be restored, air is stored in the heat-insulating cavity 4 through the heat-insulating cavity 4 formed between the supporting yarn 3 and the yarn core 1, the air is not easy to flow through storing the air in the heat-insulating cavity 4, the overall heat-insulating performance of the yarn is improved, and more air is restricted while the yarn keeps a fluffy state in use, thereby better reach and obtain better warmth retention property when increasing stiff and smooth sense to through the further improvement of supplementary yarn 5 support yarn 3's bulk strength, thereby let the yarn be difficult for by the deformation of offset pressure when using.

The most remote point that supporting yarn 3 and arch 2 kept away from yarn core 1 is on the circle of same diameter, lets the yarn keep cylindricly at the macroscopic view level to it is more convenient when letting the use, and can effectual reduction surperficial unsmooth degree, thereby reduce roughness, make more in the same direction as smooth when using of yarn. The middle part of the yarn core 1 is provided with the hollow cavity 6, the hollow cavity 6 can further store more air, so that the overall warmth retention performance of the yarn is improved, the hollow cavity 6 can enable the yarn to obtain the wicking effect, and when sweat enters the hollow cavity 6, the sweat can be rapidly discharged through the wicking effect, so that the accumulation of the sweat is avoided. The yarn core 1, the supporting yarn 3 and the supplementing yarn 5 are integrally formed by polypropylene and are sprayed, and the whole yarn is directly sprayed by a spinneret plate, so that the production process is simpler, and the problem that the yarn cannot be used due to overhigh process cost in production is avoided.
