Manufacturing method for novel one-piece seamless underwear

Abstract

The invention provides a manufacturing method for novel one-piece seamless underwear, and relates to the manufacturing method for the underwear. The manufacturing method comprises the steps of (1) positioning, (2) shaping, and (3) treating with ultrasonic waves. The novel one-piece seamless underwear has the advantages of tension resistance, lightness, high security, long service life and the like, and has a function of antioxidation.

Description

Technical field: [0001] The invention relates to a method for making underwear, in particular to a method for making a novel one-piece seamless underwear. Background technique: [0002] The traditional bra has the inner tank shaping process as follows: 1. The inner tank is shaped: the operator first puts a piece of non-glued cotton into the inner tank mold and heats it for 80 seconds, then places the steel bow that has been sprayed with glue, and then puts the steel bow on the heart Put another layer of shaped yarn, then put a piece of collodion, press the start switch, heat press for 220 seconds to complete the setting, after cooling, professional trimmers will cut off the excess along the mold line, and then The glue spraying department sprays glue; the second and second overall finalization: it consists of 2 people, namely the front operator and the rear operator. The mold is the punch on the bottom, the middle splint, and the die on the top. In the middle of the splint,...

Problems solved by technology

[0006] The invention has the following beneficial effects: 1. It solves the problem of non-cracking and constant chicken hearts. The chicken hearts can withstand a pulling force of 50 kg, and the weight is light; 2. It does not need to be crossed, but instead uses infrared and far-outline positioning, and the positioning and fixing machine is equipped with sensors , People will never press their fingers when operating the machine, and the safety performance has been improved several times; 3. It does not need an inner liner, and uses hand-push cotton + chicken heart + cloth double-layer Japanese imported fabrics, which can withstand high temperatures of 200 degrees, and use shaped yarn for clamping and bending Due to the fixed side clamping and bending, the shoulder strap hanging position will not break, and the chicken heart will not break. It can withstand nearly 100 kg of pressure, prolonging the service life of the bra and making it more economical to use; 4. It has a convex mold on the top and a concave mold on the bottom. The one-piece type is just the opposite, and in the new technology, it is convenient to add double-layer chicken heart cloth, clamping yarn, and a layer of high-elastic elastic net is successfully added to the side wings, which solves the phenomenon that the side wings of the bra are easy to loose. It has been tested 100 times Wearing does not change the loose wings, and the traditional one-piece type takes 600 seconds at a high temperature of 190 degrees, while the new one-piece type only needs 280 seconds at a temperature of 170 degrees, which successfully shortens the high-temperature molding time and solves the yellowing caused by high temperature and long time , has antioxidant function
