Embodiment Construction

[0007] The present invention is a preparation method of corn fiber non-woven fabric, which comprises the following steps: step 1, cotton blending: mixing corn fiber and nylon fiber at a ratio of 80% and 20%, and then artificially laying them layer by layer Spread it down, spray 2kg of water containing antistatic agent on each layer for mixing, the content of antistatic agent in the water containing antistatic agent is 1‰, the weight of each layer of corn mixed fiber is 200kg, cover it with plastic film, keep The constant temperature is 25°C±2°C, and the holding time is 24 hours; step 2, feed the corn mixed fiber that has been mixed and kept wet in step 1 into the cotton hopper, and the corn fiber is opened by the bale opener to make the corn mix The fiber is loose; step 3, the corn mixed fiber is fed into the weighing cotton box and weighed, and the feeding amount of the corn mixed fiber is 20g according to the weight of the corn mixed fiber per square meter by adjusting the ph...

Abstract

The invention discloses a method for preparing corn fiber non-woven fabric, which comprises the following steps: 1, mixing 80 percent of corn fiber (PTT) and 20 percent of nylon fiber (PA6) in proportion, then manually spreading the mixture layer by layer, spraying water containing antistatic agent onto every spread layer for mixing, sealing the mixture by using a plastic film, and keeping a constant temperature for a period of time; 2, feeding the moisture-keeping corn mixed fiber after mixing into a weighing cotton box of a cotton hopper, and opening the corn mixed fiber by a bale opener to loosen the corn fiber; 3, adjusting the feeding amount of the corn mixed fiber by adjusting the photoelectric switching frequency of the weighing cotton box according to the fixed amount of a product; 4, delivering the corn mixed fiber fed by the weighing cotton box into a carding machine through an air suction device to carry out pre-carding and then fine carding; 5, evenly distributing the corn mixed fiber subjected to fine carding by three doffer carding machines onto a curtain of a lapping machine; 6, delivering the corn mixed fiber evenly distributed on the curtain of the lapping machine to a hot rolling mill to carry out heating and molding; and 7, using a lap former to lap the corn fiber non-woven fabric subjected to the heating and molding by the hot rolling mill.

Description

technical field [0001] The invention relates to a preparation method of corn fiber nonwoven fabric. Background technique [0002] The introduction of the national "Plastic Restriction Order" and the widespread use of non-woven products in food packaging, hygiene materials, clothing and other fields, and the EU's stricter control of formaldehyde content standards in export textile products, so people are concerned about their environmental protection, The requirements for easy decomposition and degradation are getting higher and higher. However, the non-woven fabrics made of PET, PP, PA6 and other fibers currently used in the market are difficult to degrade and are non-renewable resources, causing serious pollution to the environment, but corn fiber is a completely biodegradable fiber. Contents of the invention [0003] The invention provides a method for preparing corn fiber non-woven fabric. The non-woven fabric prepared by the method can not only be easily degraded, but...
