[0029] Embodiment 1: produce 90g / m 2 stretchable material

[0030] The first step of the spunlace nonwoven process to produce the substrate has the following steps:

[0031] Choose a polyester differential fiber with a fineness of 2 deniers and a length of 51 mm and a cross-section composed of two types of fibers (the fiber supplier is Japan Toyobo Industry Co., Ltd., model msw5730), and add 20% polyester differential fiber Weight of 2D*51mm fiber; use two bale opening machines to feed polyester differential fiber and polyester fiber in proportion respectively, and then go through two openings, multi-bin cotton blending, cross-laying, drafting, drum drying, hot air Spunlace nonwoven process of through-drying and functional finishing, apply antistatic oil and water at the opening or mixing place according to 8% of the total fiber weight, and the antistatic agent mixture consists of 3% antistatic agent and 97% water Composition to improve fiber carding. The main process of th...

Abstract

The invention discloses a two-step production method for elastic nonwoven material. No methods for producing elastic fabric by utilizing non-elastic fiber exist in the prior art. The invention provides the two-step production method for elastic nonwoven material, which comprises the following steps: 1) selecting polyester differential fiber and polyester fiber as raw material, adopting a spun-laced method to process the raw material and obtain a base material, applying antistatic agent mixture solution accounting for 5 to 10 percent of the total weight of the fiber to opened or mixed parts, wherein the antistatic agent mixture solution consists of antistatic agent with the mass percentage between 2 and 3 percent and water; and 2) thermally contracting the obtained base material in a loosestate in a drying room under the conditions of uniform overfeed and no tension and finally obtaining the elastic nonwoven material. The method has the advantage of solving the problem of utilizing non-elastic fabric to produce elastic fabric, and the elastic nonwoven material has the characteristics of softness, comfort, simple production process and low production cost.

Description

technical field [0001] The invention relates to the field of nonwoven material production, in particular to a two-step production method of stretchable nonwoven material. Background technique [0002] At present, there are mainly two methods for producing similar products at home and abroad. One is to use styrenic block copolymers to produce on the production line of spunbonded non-woven process. Due to the high price of elastomers, the price of products is higher, and the products do not have water absorption performance, so the market acceptance is limited. The other is to compound the elastomer between two layers of non-woven materials. The production process is more complicated, and the stretchability of the product is affected. These two products are mainly used in the personal care industry, such as diaper parts, elastic binding for infant and adult disposable care products, etc. There is currently no method for producing elastic fabrics from non-elastic fibers.
