Embodiment 1

[0036] The invention provides a crotch thermal molding process for men's underwear, comprising the following steps:

[0037] Step A: raw material preparation, cutting the knitted fabric into a square piece 1, and distinguishing the front and back of the square piece 1;

[0038] Step B: Preliminary molding of the front crotch part 3, after heating the three-dimensional oval molding mold 2 to the specified temperature, separating the pressing mold 21 and the supporting mold 22 in the three-dimensional oval molding mold 2, and then separating the square sheet 1 Place it on the supporting mold 22 and close the pressing mold 21 and the supporting mold 22, so that the square sheet 1 is hot-pressed and deformed. After heating for a specified period of time, open the three-dimensional oval molding mold 2, and heat-press the deformed Take out the square piece 1;

[0039] Step C: It is necessary to screen the hot-pressed and deformed square sheet 1, remove the defective products, and p...

Embodiment 2

[0041] As an optional embodiment, the front crotch 3 is made of elastic material, and after being washed and deformed, the front crotch 3 will retract slightly. Manual shirring can appropriately increase the space capacity and offset the shrinkage of washing and wearing deformation. After testing and comparison, the length of the bottom arc with a shrinkage of 1.5-3cm is suitable.

[0042] As an optional implementation, in step B, the heating temperature of the three-dimensional oval molding die 2 is 190°±3°, and the heating time for the square sheet 1 is 38s to 45s. In addition, the specific temperature duration can be determined according to the square sheet 1 to adjust the thickness and composition ratio.

[0043] As an optional implementation, in step B, the square sheet 1 needs to be treated with a high temperature resistance additive before hot pressing, and the high temperature resistance additive can prevent the square sheet 1 from yellowing and blackening during the h...

Embodiment 3

[0046] As an optional embodiment, the three-dimensional oval molding die 2 is provided with a heating device, the heating device can be a heating wire, the pressing mold 21 can be provided with a heating device, and there is no heating device on the supporting mold 22; or the supporting mold 22 can be provided with a heating device, but there is no heating device on the pressing die 21; or both the pressing die 21 and the supporting die 22 are provided with a heating device.

[0047] As an optional embodiment, the pressing mold 21 is provided with an outwardly protruding semi-oval portion 211, and the supporting mold 22 is provided with an inwardly recessed semi-oval groove 221, the semi-oval portion 211 can extend into half Oval groove 221 and the two match. The square sheet 1 is placed between the semi-oval portion 211 and the semi-oval groove 221, and then the semi-oval portion 211 and the semi-oval groove 221 can heat-press the square sheet 1 into a semi-oval structure. T...

Abstract

The invention provides a crotch hot mold pressing process of male underpants and the male underpants, relates to the technical field of garment processing, and solves the technical problem of uncomfortable wearing experience of the male underpants in the prior art. The method comprises the following steps: step A, preparing raw materials, namely cutting a knitted fabric into square pieces; b, preliminarily forming a front crotch, heating a three-dimensional oval mold pressing mold to a specified temperature, separating a pressing mold and a bearing mold in the three-dimensional oval mold pressing mold, placing the square sheet on the bearing mold, closing the pressing mold and the bearing mold so as to enable the square sheet to be subjected to hot pressing and deformation, heating for a specified duration, and then forming the front crotch; opening the three-dimensional oval mold pressing mold, and taking out the square sheet subjected to hot pressing deformation; and C, sleeving the model rubber shell with the square sheet subjected to hot-pressing deformation, trimming the outer contour of the model rubber shell, and pleating the bottom end of the cut square sheet to form a front crotch part.

Description

technical field [0001] The invention relates to the technical field of garment processing, in particular to a crotch thermal molding process for men's underwear and the men's underwear. Background technique [0002] At present, there are roughly two types of men's underwear. One is the flat structure with an elastic front crotch. Although the front crotch of this type of underwear is elastic due to the flat structure when worn, it has a strong sense of oppression on the male body. , it is very uncomfortable to wear, and the user experience is very poor. The other is that the three-dimensional structure of the front crotch is made of multiple pieces of front crotch splicing to make it a three-dimensional structure, but the front crotch of this kind of underwear will have more seams, which increases the need for The weariness of the male body, and the more seams there are, the greater the risk of open stitches, the poorer the quality of men's underwear, and the uncomfortable w...
