Abstract

An environmentally-friendly breathable vertical cotton bra cup comprises a bra cup body. The bra cup body comprises a beautifying core and fabric wrapping an outer layer and an inner layer of the beautifying core. The beautifying core is of a honeycomb three-dimensional structure. The fabric is sandwich fabric provided with a three-dimensional meshed structure. Compared with the prior art, the environmentally-friendly breathable vertical cotton bra cup provided in the present invention has better breathability, higher wearing comfortableness and can be recycled, and better meets environmental protection requirements.

Description

An environmentally-friendly breathable cotton cup

Technical field

The present invention relates to a bra cup, and more particularly to an environmentally friendly breathable riser cup.

Background technique

At present, most of the bra cups on the market are mainly sponge cups. The sponge cup is formed by using a sheet or a block of polyurethane (PU) foam sponge material through a mold at a certain high temperature and high pressure. However, there are certain defects in the production and use of the sponge cup: 1) The PU sponge is made by chemical reaction and foaming. The unstable chemical structure will dissipate toxic substances during the processing of the cup or when the human body is worn, which will cause certain environmental damage. Contamination has certain adverse effects on the human body; 2) The original loose structure of the sponge body becomes dense, which makes the product's gas permeability greatly reduced, which affects the wearing comfort of the sponge cup; 3) After the sponge product is placed for a long time, Chemical yellowing and aging will occur, affecting product perception and performance; 4) Sponge cups in production cannot be recycled immediately due to the large amount of sponge scraps produced by stereotype cutting. After sale, sponge cup products cannot be recycled after wearing. Recycling does not meet the environmental requirements that people are increasingly pursuing.

Summary of the invention

In order to overcome the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a bra cup which is more breathable, recyclable, and more environmentally friendly.

In order to achieve the above object, the present invention provides an environmentally-friendly breathable riser cup, comprising a cup body, the cup body comprising a core, a fabric coated on the outer layer of the core and an inner layer, wherein the core is An upright cotton having a honeycomb-like three-dimensional structure, the fabric being a sandwich fabric having a three-dimensional mesh structure.

The upright cotton has the same resilience and better breathability as the sponge, while the sandwich fabric has good elasticity and excellent breathability. Therefore, the cup body having the above structure has better gas permeability than the sponge cup product.

Preferably, the side of the sandwich fabric coated with the outer layer of the ferrule is also attached with a thin layer of erect cotton toward the side of the embossed core. The upright cotton layer facilitates the predetermined shape of the outer layer of the sandwich fabric, and increases the adhesion fastness of the outer layer of the sandwich fabric to the quilted upright cotton. More preferably, the thickness of the upright cotton layer is 2-5 mm. Among them, 3mm is the most ideal thickness.

Preferably, the upright cotton is made of thermally bonded polyester filament fiber, heat-shrinkable polyester filament fiber, and polyester staple fiber. The heat-bonded polyester filament fiber ensures the heat-settable product and improves the elasticity and strong support of the product. The heat-shrinkable polyester filament fiber ensures the shape retention and wrinkle resistance of the mold cup. The above three kinds of fibers are made into an upright cotton having a honeycomb-like three-dimensional structure by opening cotton, mixing cotton, carding, forming, drying, shaping and cooling, and the upright cotton has the same resilience as the sponge, and the rebound elasticity can be More than 98%, and the hand feels more soft. The erect cotton is used as the cotton cup of the American core, which is not easy to be deformed, is not easy to wrinkle, and has excellent water washing and shape retaining performance. The erect cotton can be used to make a 100% erected cotton cup without the use of a sponge, which makes the underwear material single, which is beneficial to recycling and environmental protection. In addition, the erect cotton trim produced in the cutting can be recycled immediately. Reopening cotton, blending cotton and finally making upright cotton improves the utilization of raw materials, reduces waste of resources, and is more environmentally friendly.

Preferably, the cup body is molded at one time from an upright cotton and a sandwich fabric.

By adopting the above technical solution, the invention has the following advantages: 1) the sandwich fabric adopting the honeycomb structure and the three-dimensional mesh structure, the air permeability of the cup product is increased, and the comfort of the cup is improved; 2) erecting Cotton is a pure fiber product, which has healthier and environmentally friendly characteristics compared to sponges made by chemical reaction. 3) Upright cotton can be recycled and recycled after production and use, which improves raw material utilization and reduces waste of resources. Environmental requirements.

detailed description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 2 , the embodiment provides an environmentally-friendly breathable riser cup, comprising a cup body 1 , the cup body 1 including a core 10 and an outer layer 20 and a bag wrapped on the outer layer of the core 10 The inner layer fabric 30 covering the inner layer of the core 10 is added. Among them, the plus core 10 is an upright cotton having a honeycomb-like three-dimensional structure, and the inner layer fabric 30 and the outer layer fabric 20 are sandwich fabrics having a three-dimensional mesh structure.

A thin layer of upright cotton 21 is also adhered to one side of the outer layer fabric 20 covering the outer layer of the embossed core 10 toward the mering core 10. The upright cotton sheet 21 facilitates the predetermined pattern of the outer layer 20 while increasing the adhesion of the outer layer 20 to the plus core 10. The thickness of the upright cotton layer is 2-5 mm, and the embodiment has an optimum thickness of 3 mm.

In this embodiment, the upright cotton is made of thermally bonded polyester filament fiber, heat-shrinkable polyester filament fiber, and polyester staple fiber. The manufacturing method of the erect cotton is specifically as follows:

(1) Open and mixed cotton: 35~45% by weight of thermally bonded polyester filament fiber, 25~35% of heat-shrinkable polyester filament fiber and 20~40% of ordinary polyester staple fiber The raw material fibers are fully opened and uniformly mixed to form a crepe cotton;

(2) carding: combing the quilted cotton into a mutually interwoven cotton web having a certain density and thickness;

(3) Forming: reciprocating the cotton web to form S Forming a head-to-tail joint structure, extruding the structure to interweave the cotton webs to form a wavy strand cotton web layer;

(4) drying and setting: drying the lining mesh layer to make the adjacent fibers of the lining mesh layer adhere to each other and shrink, forming a hot air cotton having a honeycomb-like three-dimensional structure;

(5) Cooling and setting: The hot air cotton is cooled and shaped into an upright cotton.

The erect cotton prepared by the above method is subjected to one-time compression molding by a hot pressing die after being cut and a predetermined type of sandwich fabric to obtain a cup body.

The above embodiments are only intended to illustrate the technical idea and the features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention. Equivalent changes or modifications made to the spirit of the spirit should be covered by the scope of the present invention.
