preparation example Construction

[0022] The present invention also provides a preparation method of the corn polylactic acid fiber fabric described in the above technical solution, comprising the following steps:

[0023] Laminate a breathable film on the surface of corn polylactic acid fiber spunlace non-woven fabric to obtain a semi-finished fabric;

[0024] Perforating and drying one side of the semi-finished corn polylactic acid fiber spunlace nonwoven fabric to obtain the corn polylactic acid fiber fabric.

[0025] In the present application, firstly, a breathable film is laminated on one side of the corn polylactic acid fiber spunlace nonwoven fabric; the material of the breathable film is preferably TPEE, and the thickness of the breathable film is preferably 2 to 5 μm, more preferably 2 to 5 μm. 3μm; the lamination temperature is preferably 40-60°C, more preferably 60°C, the pressure is preferably 0.4-0.6Mpa, more preferably 0.4Mpa; a zero-tension film release device is preferred during lamination to ...

Embodiment 1

[0031] The preparation of corn polylactic acid fiber spunlace non-woven fabric: firstly, corn grains are used as raw materials, which are fermented and converted into lactic acid, then polymerized and spun to make corn polylactic acid fibers, and then corn polylactic acid fibers are prepared from corn polylactic acid fibers. Fiber spunlace non-woven fabrics, extraction of corn polylactic acid fibers and preparation of spunlace non-woven fabrics can all be done in any way known to those skilled in the art;

[0032] Preparation of corn polylactic acid fiber fabric: put the corn polylactic acid fiber spunlace non-woven fabric prepared above and 2 μm thick TPEE breathable film on the self-made equipment, turn on the equipment, and laminate the TPEE breathable film to the corn polylactic acid fiber water The surface of the non-woven fabric is punctured, the lamination temperature is 60°C, and the pressure is 0.4Mpa. After the lamination, the equipment is stopped to obtain a semi-fin...

Abstract

The invention provides a corn polylactic acid fiber fabric, which comprises a corn polylactic acid fiber spunlaced non-woven fabric layer and a breathable film layer. One side of the corn polylactic acid fiber spunlaced non-woven fabric layer is equipped with funnel-shaped small holes. The corn polylactic acid fiber fabric provided by the invention has good degradability, breathability and bacteriostasis, and has no adverse effect on the skin and environment; the breathable film layer is laminated on the surface of the corn polylactic acid fiber spunlaced non-woven fabric, and can reach the effects of dryness and good breathability; and the funnel-shaped small holes disposed on one side of the corn polylactic acid fiber spunlaced non-woven fabric have unidirectional moisture absorption effect. The invention also provides a preparation method of the corn polylactic acid fiber fabric. The method includes: laminating the breathable film on the surface of the corn polylactic acid fiber spunlaced non-woven fabric to obtain a semi-finished fabric product; and conducting punching on one side of the corn polylactic acid fiber spunlaced non-woven fabric semi-finished product, and performingdrying, thus obtaining the corn polylactic acid fiber fabric. The method is simple to operate and easy to implement.

Description

technical field [0001] The invention relates to a fabric, in particular to a corn polylactic acid fiber fabric and a preparation method thereof. Background technique [0002] Most of the sanitary napkins, diapers and adult nursing pads on the market are a liquid absorption control system established by multi-layer non-woven materials. According to the structure, it is generally composed of surface covering layer, absorbent core layer and bottom film, etc. composition. At present, the surface layers of sanitary napkins and diapers mainly use spunbond, SMS or hot-air bonded nonwovens, and the back layer is mainly a breathable film laminated with spunbonded nonwovens. [0003] However, most of the products such as diapers and sanitary napkins on the market are mostly made of chemical fiber materials, which are non-degradable, non-renewable, poor in air permeability, and have chemical residues, which have adverse effects on human skin and even health, and the surface of the pro...
