The utility model provides a following technical scheme:

a polylactic acid underwear fabric comprises an outer layer, a middle layer, an inner layer and a flocking layer which are sequentially connected from outside to inside, wherein the outer layer, the middle layer and the inner layer are connected by cotton yarn in a sewing way; the outer layer is woven by polylactic acid fiber and elastic filament, the middle layer is woven by mixed yarn of polyurethane elastic fiber and polylactic acid fiber, the inner layer is woven by polylactic acid fiber and elastic filament, the flocking layer is composite fiber consisting of polylactic acid fiber and moisture absorption heating fiber, and the flocking layer is vertically bonded on the inner layer.

Preferably, the mixed yarn in the middle layer is wrapping yarn, the core layer of the wrapping yarn is polyurethane elastic fiber, the wrapping layer of the wrapping yarn is polylactic acid fiber, and the wrapping layer is spirally wrapped outside the core layer; air gaps are respectively formed between the wrapping layer and the outer layer and between the wrapping layer and the inner layer.

Preferably, the composite fiber of the flocking layer is in a core-spun yarn structure, the core-spun yarn is formed by spinning a spinneret plate with a corresponding core-spun structure, the inner core layer of the core-spun yarn is the moisture absorption heating fiber, and the outer cladding layer of the core-spun yarn is the polylactic acid fiber.

Preferably, the outer layer and the inner layer are both woven by pure polylactic acid fiber 30-300D elastic filaments.

Preferably, the cotton yarn is a fine yarn of 11-20 tex.

The utility model has the advantages that: the polylactic acid underwear fabric of the utility model is provided with an outer layer, a middle layer, an inner layer and a flocking layer, wherein the middle layer is formed by weaving the mixed yarn of polyurethane elastic fiber and polylactic acid fiber, and the polyurethane elastic fiber increases the elasticity and the heat retention of the underwear fabric, thereby being suitable for being worn next to the skin; the outer layer and the inner layer are both woven by polylactic acid fiber and elastic filament, so that the fabric has good elasticity and skin-friendly antibacterial activity; the flocking layer on the inner side of the inner layer can increase the skin-friendly touch feeling, so that the underwear is more comfortable and warm to wear; the flocking layer contains moisture absorption heating fiber, and the moisture absorption heating fiber can absorb sweat moisture secreted by the skin on one hand, and on the other hand, the moisture absorption and the heat retention of the underwear are improved by utilizing the absorbed moisture to generate heat. The flocking layer is a core-spun composite fiber formed by spinning polylactic acid fiber and moisture-absorbing heating fiber, and has better skin-friendly property and heat retention property.

Detailed Description

As shown in fig. 1 and 2, the polylactic acid underwear fabric comprises an outer layer 1, a middle layer 2, an inner layer 3 and a flocking layer 4 which are sequentially connected from outside to inside. The outer layer 1, the middle layer 2 and the inner layer 3 are connected by cotton yarn in a sewing way, and the cotton yarn is fine yarn of 11-20 tex; the outer layer 1 and the inner layer 3 are both woven by pure polylactic acid fibers 30-300D elastic filaments, so that the fabric keeps good elasticity.

The middle layer 2 is woven by mixed yarn of polyurethane elastic fiber and polylactic acid fiber, the flocking layer 4 is composite fiber spun by the polylactic acid fiber and the moisture absorption heating fiber, and the flocking layer 4 is vertically bonded on the inner layer.

Specifically, the mixed yarn of the intermediate layer 2 is a wrapped yarn, the core layer 21 is a polyurethane elastic fiber, the wrapped layer 22 is a polylactic acid fiber, the wrapped layer 22 is spirally wrapped outside the core layer 21, the elasticity and the heat preservation performance of the polyurethane elastic fiber are good, and the elasticity of the polylactic acid fiber is smaller than that of the polyurethane elastic fiber, so that when the polyurethane elastic fiber is stretched, the elasticity difference between the polylactic acid fiber spirally wrapped outside the polyurethane elastic fiber and the polyurethane elastic fiber can be compensated, and the polylactic acid fiber and the polyurethane elastic fiber are synchronously stretched; air gaps 23 are respectively formed between the spiral structures of the wrapping layers 22 and the outer layer 1 and the inner layer 3, the air gaps 23 have the air heat preservation effect, and the heat preservation performance of the underwear fabric is further improved.

The hygroscopic exothermic fibers were eks fibers developed by toyobo.

The processing method of the utility model is as follows: the outer layer, the middle layer and the inner layer are made of the corresponding materials, the flocking layer is planted on the lower surface of the inner layer through an electrostatic flocking method, and then the layers are sewn and connected through cotton yarns.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
