Description

Technical Field

[0001] The present application relates to the field of underwear, and in particular to a velvet underwear steel ring and a preparation method thereof. Background Art

[0002] At present, women usually install steel rings under the cups of underwear to support and protect the breasts. The steel rings are inserted into the steel ring sleeves after being sewn together with other parts of the underwear. The production process and time of placing the steel rings on the underwear are reduced, and the steel ring sleeves cushion the discomfort of the hard material of the steel rings to the skin, eliminating the pressure of the steel rings to a certain extent.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the steel ferrule is usually woven with velvet thread, and the velvet thread has fluff on its surface. After being woven into the steel ferrule, the fluff directly contacts the human skin. The fluff on the steel ferrule is in close contact with the human skin, which can easily cause a tingling sensation to the skin. Summary of the invention

[0004] In order to improve the puncture resistance of the steel ferrule, the present application provides a velvet underwear steel ferrule and a preparation method thereof.

[0005] In the first aspect, the present application provides a velvet underwear steel ring adopts the following technical solution:

[0006] A velvet underwear steel ferrule comprises a steel ferrule body, which is hollow and comprises a first connecting part and a second connecting part. A connecting line is arranged between the first connecting part and the second connecting part, and the connecting line interweaves and connects the first connecting part and the second connecting part. The connecting line is made of velvet thread and hot-melt thread.

[0007] By adopting the above technical scheme, the present application fills the connecting wire on both sides of the first connecting part and the second connecting part, so that the steel ring can be inserted into the hollow position of the steel ring body. When the user wears the underwear, the steel ring will not pull the steel ring body to cause the surface of the steel ring to be rough and the elasticity to be uneven. The deformation of the steel ring body caused by the uneven tension formed by the bending of the steel ring is improved, and the effect of the steel ring fixing the steel ring is not affected; and the connecting wire of the present application is made of a mixed textile of velvet thread and hot melt thread. Since the hot melt thread has good adhesion, the hot melt thread and velvet thread are mixed and woven into a thread, so that the surface of the velvet thread is bonded to the hot melt thread, so as to avoid the surface of the velvet thread being rough due to the steel ring pulling the steel ring body when the steel ring is set or the user wears the underwear, which makes the wearer feel tingling. After the hot melt thread and velvet thread are mixed and woven, the surface of the velvet thread can be made softer.

[0008] Preferably, the hot melt is a modified hot melt, which comprises the following raw materials in parts by weight: 30-60 parts of hot melt, 10-20 parts of chitosan, 8-16 parts of polyetheramine, 5-15 parts of hexamethylenediamine, 10-20 parts of diphenylmethane diisocyanate, 2-8 parts of crosslinking agent and 2-6 parts of antistatic agent.

[0009] By adopting the above-mentioned technical scheme, the present application modifies the hot melt wire. The modified hot melt wire can be bonded to the surface of the velvet thread, making the surface of the velvet thread smoother and improving the puncture resistance of the steel ring body; at the same time, the modified hot melt wire and the velvet thread can generate more entanglement during the weaving process, thereby improving the bonding force between the two, thereby improving the tensile breaking strength of the connecting line.

[0010] Preferably, the modification steps of the modified thermal fuse are:

[0011] Step (1): mixing the hot melt wire with chitosan, adding polyetheramine to the hot melt wire with chitosan for ultrasonic reaction, and heating and stirring with hexamethylenediamine to obtain a premix;

[0012] Step (2): adding diphenylmethane diisocyanate, a cross-linking agent and an antistatic agent to the premix, stirring evenly, leaving the mixture to stand and soak, washing with water and drying to obtain the modified hot melt wire.

[0013] By adopting the above technical scheme, the present application mixes chitosan, polyetheramine, hexamethylenediamine, diphenylmethane diisocyanate and hot-melt wire. The hot-melt wire is ultrasonically stirred, heated and mixed, and then left to soak. After the modified hot-melt wire is woven with velvet thread, the connecting wire has better puncture resistance and tensile strength.

[0014] Preferably, the weight ratio of chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate is (0.7-0.9):(1.2-1.3):1:(1.1-1.3).

[0015] By adopting the above technical scheme, when chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate are in a specific ratio, chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate work together to improve the tensile breaking strength between the modified hot melt thread and the velvet thread, and at the same time improve the pilling resistance of the hot melt thread.

[0016] Preferably, the antistatic agent includes one or more of glyceryl stearate, polyethylene oxide and dimethyl silicone oil. More preferably, the antistatic agent is glyceryl stearate.

[0017] By adopting the above technical solution, an antistatic agent is added in the process of preparing the modified hot-melt wire, which has the characteristics of a surfactant and can eliminate the accumulation of static charges, thereby guiding and eliminating the static electricity on the surface of the velvet steel ring body.

[0018] Preferably, the cross-linking agent includes one of melamine, benzoyl peroxide and diethylenetriamine, and more preferably, the cross-linking agent is melamine.

[0019] By adopting the above technical solution, a cross-linking agent is added during the preparation of the modified hot-melt wire to promote the connection between the hot-melt wire and chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate.

[0020] Preferably, the heating temperature when adding polyetheramine and hexamethylenediamine in step (1) is 75-85°C.

[0021] By adopting the above technical scheme, the heating temperature when adding polyetheramine and hexamethylenediamine is controlled, so that the hot melt wire reacts with polyetheramine and hexamethylenediamine more thoroughly, thereby improving the puncture resistance of the connecting wire after the modified hot melt wire and velvet thread are interwoven.

[0022] Preferably, the soaking time in step (2) is 3-5 hours.

[0023] By adopting the above technical solution, the static time of the thermal fuse is controlled, so that the effect of the modified thermal fuse is more significant.

[0024] Preferably, the weight ratio of the thermal fuse to the velvet thread is (1-2):1.

[0025] By adopting the above technical solution, the present application controls the thermal fuse and the velvet thread at (1-2):1, so that the thermal fuse and the velvet thread are staggered, so that the thermal fuse and the velvet thread can be better bonded together, making the connecting line more flexible.

[0026] In a second aspect, the present application provides a method for preparing a velvet underwear steel ferrule, which adopts the following technical solution: A method for preparing a velvet underwear steel ferrule, comprising the following steps:

[0027] S1. Weaving the first connecting part and the second connecting part using connecting wires respectively;

[0028] S2. Use connecting wires to connect the two sides of the first connecting part to the two sides of the second connecting part respectively, and weave to form a mesh surface.

[0029] By adopting the above technical solution, the hot fuses and the velvet threads are woven into a mesh surface, so that the hot fuses are arranged at intervals, and adjacent hot fuses will not adhere to each other, thereby maintaining the softness of the velvet threads.

[0030] In summary, this application has the following beneficial effects:

[0031] 1. The present application fills the connecting wires on both sides of the first connecting part and the second connecting part, so that the steel ring can be inserted into the hollow position of the steel ring sleeve body. When the user wears the underwear, the steel ring will not pull the steel ring sleeve body to cause the steel ring sleeve surface to be rough and the elasticity will not be uneven. The deformation of the steel ring sleeve body caused by the uneven tension formed by the bending of the steel ring is improved, and the effect of the steel ring sleeve fixing the steel ring is not affected; and the connecting wire of the present application is made of velvet thread and hot melt thread mixed weaving. Since the hot melt thread has good adhesion, the hot melt thread and the velvet thread are mixed and woven into a thread, so that the surface of the velvet thread is bonded with the hot melt thread, so that the surface of the velvet thread is not caused by the steel ring pulling the steel ring sleeve body when the steel ring is set or the user wears the underwear, causing the surface of the velvet thread to be rough, which causes the wearer to feel stinging. After the hot melt thread and the velvet thread are mixed and woven, the surface of the velvet thread can be made more smooth;

[0032] 2. In the present application, chitosan, polyetheramine, hexamethylenediamine, diphenylmethane diisocyanate and hot-melt wire are mixed, and the hot-melt wire is ultrasonically stirred, heated and mixed, and then allowed to stand and soak, so that after the modified hot-melt wire and velvet wire are woven, the connecting wire has better puncture resistance and tensile strength;

[0033] 3. When chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate are in a specific ratio, chitosan, polyetheramine, hexamethylenediamine and diphenylmethane diisocyanate work together to improve the tensile breaking strength between the modified hot melt wire and the velvet wire, and at the same time improve the pilling resistance of the hot melt wire.
