Embodiment 1

[0021] In the present invention, it is first necessary to carry out the deammonization aging process to natural rubber. Generally, the ammonia content is required to be reduced to 0.2% to 0.25%. First, the natural rubber latex is filtered, and 20 parts of KOH solution is added therein after filtering, and stirred while adding, stirring for 3 After 10 minutes, slowly add 20 parts of oxalic acid. This is an exothermic reaction, so the temperature of the latex will rise when adding oxalic acid. If the temperature of the latex rises above 12 degrees, it should be stopped and added after the temperature drops. Stir for 18 minutes, add another 12 parts of trypsin, stir for 5 minutes, cover and seal, and mature at room temperature for 24 hours. After the latex is ripe, it should be filtered and used, and the service life is 144h.

Embodiment 2

[0023] As in the deammonization ripening process in Example 1, after adding KOH solution, stir for 4 minutes, slowly add 20 parts of oxalic acid, stir for 20 minutes, add 18 parts of trypsin, stir for 5 minutes, cover and seal, and ripen for 36 hours at room temperature .

Embodiment 3

[0025] As in the deammonization ripening process in Example 1, after adding KOH solution, stir for 4 minutes, slowly add 20 parts of oxalic acid, stir for 20 minutes, add 15 parts of pancreatin, stir for 5 minutes, cover and seal, and ripen for 72 hours at room temperature , when adding oxalic acid, if the temperature of the latex rises above 12 degrees, stop adding, and continue to add after the temperature of the glue drops. The value is around 9 to 11.5.

[0026] The ammonia content in the latex should be reduced to about 0.2% as much as possible. If it exceeds, gelation will be delayed and the amount of gelling agent will be increased.

Abstract

The invention provides an underwear mold cup. The underwear mold cup comprises, by weight, 120 parts of natural rubber latex, 20 parts of oxalic acid, 12 to 18 parts of pancreatin, 1.5 to 3 parts of auxiliary agents, 45 to 60 parts of potassium ricinoleate soap, 100 parts of sulfur, 100 to 120 parts of zinc diethyl dithiocarbamaate, 45 to 50 parts of ammonium bicarbonate, 25 to 30 parts of sodium lauryl sulfate, 1.5 to 3 parts of an amphoteric oxide, a delayed coagulant, 10 to 20 parts of potassium silicofluoride and 0.1 to 1 part of an antiager. Through deamination aging, foaming, bed cutting, cotton pushing and setting, the underwear mold cup is obtained. The underwear mold cup has good breathability and can rapidly release heat and moisture generated by the human body. The natural rubber has good elasticity and a strong memory function. The underwear mold cup can support breast according to ergonomics, effectively maintain the natural structure of the breast and prevent breast displacement or sagging.

Description

technical field [0001] The invention relates to the field of natural rubber materials, in particular to an underwear mold cup. Background technique [0002] Underwear is a product used to protect women's health and make breasts more beautiful. Existing underwear with molded sponge as a pad can increase the charm to a certain extent after women wear it. But there are many deficiencies in this underwear with sponge (polyurethane) as the liner, mainly in: poor air permeability of the sponge liner, poor elasticity, and there will be stuffy feeling when wearing this underwear. This situation is more serious in summer, although there are some Holes are punched on the sponge liner to enhance air permeability, but the sponge liner after punching is easily deformed and damaged; due to the poor elasticity of the sponge, it is easy to deform, so this kind of underwear is easily deformed after being washed many times, the sponge is easy to age, and the sponge body Easy to breed bacter...
