Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to a bio-based high-elastic body-shaping fabric. Background Art

[0002] Elastic body-shaping fabrics generally refer to knitted fabrics blended or woven with spandex and other chemical fibers. They can be used in products such as shapewear, swimwear, and post-operative recovery apparel. For example, a shapewear swimsuit is disclosed in Chinese patent document CN207978994U. However, these shapewear fabrics, when worn, come into direct contact with the skin, resulting in limited comfort and difficulty meeting the needs of post-operative patients or those recovering from breastfeeding. Furthermore, their waterproofness is also limited. Utility Model Content

[0003] The purpose of the utility model is to provide a bio-based high-elastic body-shaping fabric, which can maintain the basic body-shaping function and at the same time has good moisture permeability, air permeability, waterproof and antibacterial functions.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The bio-based high-elastic body-shaping fabric includes a warp-knitted body and a PLA electrospun nanoporous membrane. The PLA electrospun nanoporous membrane is compounded on the inner surface of the warp-knitted body. The warp-knitted body is woven by a comb bar GB1 and a comb bar GB2. The comb bar GB1 is woven with bio-based nylon 56 yarn into an open warp plain weave, and the comb bar GB2 is woven with spandex yarn into a heavy warp weave.

[0006] Preferably, the yarn inlay number of the combing bar GB1 is 01 / 21 / / .

[0007] Preferably, the yarn inlay number of the combing bar GB2 is 31 / 02 / / .

[0008] Preferably, the ratio of bio-based nylon 56 yarn to spandex yarn in the warp knitted body is 52:48.

[0009] Preferably, the specification of the bio-based nylon 56 yarn is 30D / 34F FD yarn, and the bio-based nylon 56 filament is a highly oriented yarn.

[0010] Preferably, the breaking strength of the bio-based nylon 56 yarn is 3.8 cN / dtex-4.3 cN / dtex, and the breaking elongation is 60%-65%.

[0011] Preferably, the spandex yarn has a specification of 40D.

[0012] Preferably, the PLA electrospun nanoporous membrane is compounded on the inner surface of the warp knitted body through a hot melt adhesive mesh.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The body-shaping fabric of the utility model comprises a warp-knitted main body and a PLA electrostatically spun nano-microporous membrane. On the one hand, the special weaving method makes the spandex yarn very long and the spandex content high, so that the overall fabric has the characteristics of good elastic recovery, fatigue resistance, tight fabric, large modulus strength, etc. The fabric structure and weaving process have the characteristics of tight structure, excellent tensile resilience, good elastic recovery rate, and small plastic deformation rate; on the other hand, the PLA electrostatically spun nano-microporous membrane makes the fabric have the functions of breathable and moisture-permeable, waterproof, and antibacterial. When combined with swimsuit fabric, it can effectively protect the skin and mucous membranes in complex environments such as sea swimming and swimming pools, and has good biocompatibility, meeting the needs of patients with trauma, plastic surgery, and those recovering their body shape during breastfeeding.

[0017] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0018] like Figure 1-Figure 2 As shown, this embodiment provides a bio-based, highly elastic, body-shaping fabric comprising a warp-knitted body 10 and a PLA electrospun nanoporous membrane 20. The PLA electrospun nanoporous membrane 20 is bonded to the inner surface of the warp-knitted body 10 via a hot-melt adhesive mesh 30. This allows the fabric to maintain its basic body-shaping properties while also exhibiting excellent moisture permeability, breathability, waterproofing, and antibacterial properties. The PLA electrospun nanoporous membrane 20 in this embodiment is constructed using PLA nanofibers with diameters of 50 to 100 nm. The interlaced structure of the PLA nanofibers, at the nanometer scale, provides excellent waterproofing.

[0019] In this embodiment, a KARL MAYER HKS2-SE warp knitting machine is used for weaving, using a 32G model with an effective width of 152 cm and a grammage of 190 g. The warp knitted body 10 is knitted by a comb bar GB1 and a comb bar GB2. The comb bar GB1 is woven with bio-based nylon 56 yarn into an open warp plain weave, and the comb bar GB2 is woven with spandex yarn into a heavy warp weave. The inlay yarn numbers of comb bar GB1 are 01 / 21 / / , and the inlay yarn numbers of comb bar GB2 are 31 / 02 / / . This special weaving method allows for very long spandex yarn feeds and a high spandex content, resulting in a fabric with good elastic recovery, fatigue resistance, a compact fabric, and a high modulus.

[0020] In this embodiment, the warp knitted body 10 comprises bio-based nylon 56 yarn and spandex yarn in a ratio of 52:48. The spandex yarn is 40D, while the bio-based nylon 56 yarn is 30D / 34F FD. The bio-based nylon 56 filaments are highly oriented yarns with a breaking strength of 3.8-4.3 cN / dtex and an elongation at break of 60%-65%. Highly oriented HOY filaments offer greater elongation, further enhancing the fabric's elastic recovery.

[0021] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected.
