Abstract

The invention provides a compound sponge cup with a soft and hard combined touch and a production method. The sponge cup is soft and elastic, the average density of the sponge cup subjected to foam forming is 25 kg / m<3>, the hardness is 20-25 (with reference to the ASTMD2240-97 standard), the resilience rate is 40%, the elongation is equal to or larger than 180%, the extension strength is equal toor higher than 100 kpa, and the tear strength is equal to or higher than 200 N / M. The sponge cup is subjected to high-temperature heat-setting operation after being subjected to foam forming, spongedoes not deform when heated and compressed in a mould pressing process, during hardness change, five hardness points can be controlled, and not only is a soft hand feeling retained, but also support of the cup is improved, so that the compound sponge cup with the soft and hard combined touch has wearing comfort and crispness and stability of a cup structure at the same time.

Description

technical field [0001] The invention belongs to the field of sponge foaming technology, and in particular relates to a composite sponge cup with a combination of soft and hard touch and a manufacturing method thereof. Background technique [0002] With the improvement of consumers' requirements for the comfort of bras, it is gradually difficult for the sponge cups on the market to meet consumers' inner standards. [0003] At present, there are mainly two molding methods for sponge cups: ① foam molding; ② high-temperature heat setting. Whether it is foam-molded sponge cups or high-temperature heat-set sponge cups, the hardness index of the sponge cups will change a lot and sharply during the preparation process. As the hardness increases, the softness and wearing comfort of the cup decrease significantly. [0004] For example, foam foam cups are directly molded by foaming the sponge and cup molds. During the foam molding process of ordinary foam foam cups, the hardness will ...
