Description

Technical Field

[0001] The utility model relates to the technical field of textile yarns, in particular to a cold expansion breathable and down-proof yarn. Background Art

[0002] Down jackets are one of the most common warm clothing in winter. They are mainly made of down and coated fabrics. The most common down fillings are goose down and duck down. A common problem with down jackets is that the down will run after being worn and washed for a period of time. In order to prevent the down from running, the existing down jacket fabrics woven from yarns are generally treated with surface film or calendering. The treatment process is relatively troublesome, and the fabrics treated with surface film or calendering have poor air permeability and are uncomfortable to wear. In addition, the down will still run after the surface is worn out for a period of time. Summary of the invention

[0003] The utility model aims to solve the problems in the prior art and provides a cold expansion breathable anti-down yarn, which has the characteristics of thermal contraction and cold expansion. When the temperature of the woven fabric is low, the gap between the yarns will be further reduced, effectively preventing down from running.

[0004] In order to achieve the above object, the technical solution of the utility model is:

[0005] A cold expansion breathable down proof yarn comprises a nylon core yarn, an antibacterial and antistatic layer arranged outside the nylon core yarn, and a cold expansion layer arranged outside the antibacterial and antistatic layer, wherein the cold expansion layer is provided with cold expansion particles and mineral particles by secondary spraying.

[0006] Preferably, the cold expansion layer is a PU foam layer, and the cold expansion particles are particles formed by spraying the PU foam.

[0007] Preferably, the mineral particles are mica crystals, jade or composite minerals.

[0008] Preferably, the antibacterial and antistatic layer is a nano silver paste layer mixed with bamboo charcoal fibers.

[0009] Preferably, the diameter of the nylon core yarn is 0.5-0.6 mm, the thickness of the antibacterial and antistatic layer is 0.12-0.16 mm, and the thickness of the cold expansion layer is 0.18-0.22 mm.

[0010] Preferably, the nylon core yarn is a hollow nylon yarn having a hollow portion therein.

[0011] Preferably, the hollow portion is filled with PU foam.

[0012] The utility model has the following beneficial effects: a cold expansion breathable anti-down yarn of the utility model comprises a nylon core yarn, an antibacterial antistatic layer arranged outside the nylon core yarn, and a cold expansion layer arranged outside the antibacterial antistatic layer, and cold expansion particles and mineral particles are arranged outside the cold expansion layer by secondary spraying; the cold expansion layer is a PU foam layer, and the cold expansion particles are particles formed by spraying the PU foam; the fabric woven with the cold expansion breathable anti-down yarn has micropores for preventing down from running, and has good air permeability due to the design of the cold expansion particles and mineral particles on the surface. When the temperature is low, the mineral particles quickly conduct the low temperature to the cold expansion layer, and the cold expansion layer and the cold expansion particles expand in volume, further reducing the gap between the yarns, so that the fabric has a more excellent ability to prevent down from running, as well as windproof and warmth retention when used in winter. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 for Figure 1 Enlarged view of point A in the middle. DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0016] like Figure 1-Figure 2 A cold expansion breathable anti-down yarn is shown, comprising a nylon core yarn 1, an antibacterial and antistatic layer 2 arranged outside the nylon core yarn 1, and a cold expansion layer 3 arranged outside the antibacterial and antistatic layer 2, wherein the cold expansion layer 3 is provided with cold expansion particles 31 and mineral particles 32 by secondary spraying. The cold expansion layer 3 is a PU foam layer, and the cold expansion particles 31 are particles formed by spraying the PU foam. PU foam, i.e., polyurethane foam, has the characteristics of thermal contraction and cold expansion of polyurethane, and its volume changes with temperature within a certain temperature range. Specifically, when the temperature rises, the polyurethane will shrink and its volume will decrease; when the temperature drops, the polyurethane will expand and its volume will increase. The mineral particles 32 can be mica crystals, jade or composite minerals. Taking mica crystals as an example, they have good thermal conductivity. When the external temperature is low, the mica crystals can quickly conduct the low temperature to the cold expansion layer 3, causing it to expand in volume.

[0017] As a preferred solution, the antibacterial and antistatic layer 2 is a nano silver paste layer mixed with bamboo charcoal fiber. Bamboo charcoal fiber has the effects of moisture absorption, breathability, antibacterial and antibacterial. When combined with nano silver paste, it can improve the feel of the yarn. At the same time, since nylon is prone to static electricity, the nano silver paste layer mixed with bamboo charcoal fiber can solve the static electricity problem while providing excellent antibacterial effect, making the fabric less likely to generate static electricity. The diameter of the nylon core yarn 1 is 0.5-0.6mm, the thickness of the antibacterial and antistatic layer 2 is 0.12-0.16mm, and the thickness of the cold expansion layer 3 is 0.18-0.22mm. Among them, the nylon core yarn 1 can be a hollow nylon yarn, and the hollow nylon yarn has a hollow part 11 inside. The hollow part 11 can also be filled with PU foam, so that the yarn has a double cold expansion structure inside and outside, and a better expansion effect can be achieved at a lower temperature.

[0018] The fabric woven with the cold expansion breathable anti-down yarn has micropores for preventing down from running, and has good air permeability, due to the design of the cold expansion particles 31 and the mineral particles 32 on the surface. When the temperature is low, the mineral particles 32 quickly transfer the low temperature to the cold expansion layer 3, and the cold expansion layer 3 and the cold expansion particles 31 expand in volume, further reducing the gaps between the yarns, so that the fabric has a more excellent ability to prevent down from running, as well as windproof and warmth retention when used in winter.

[0019] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
