Embodiment 1

[0049] as attached figure 1 As shown, the present invention is a method for preparing biodegradable cotton stalk fiber non-woven fabrics. The collected cotton stalks are sent as a whole to the straw kneading machine, winnowing machine, vibrating screen, and straw puffing machine for corresponding treatment. After drying, cotton stalk fibers with a diameter of 25-85 μm and a length of 2-8 cm are finally obtained for use; the prepared cotton stalk fibers are packed into fixed-weight fiber bags; , The low-melting polylactic acid fiber (PLA) with a length of 2-8cm is transported to the combined opening and cleaning machine for processing, in which the cotton stalk fiber accounts for 65wt% of the total mass of the mixed fiber; The final mixed fibers are combed into a thin fiber web; the thin fiber web is cross-laminated to form a thick new fiber web by using a cross-lapper; 60 thorns / m², made into fluffy flakes, and then use the main needling machine to carry out two main thorns o...

Embodiment 2

[0051] as attached figure 1 As shown, the present invention is a method for preparing biodegradable cotton stalk fiber non-woven fabrics. The collected cotton stalks are sent as a whole to the straw kneading machine, winnowing machine, vibrating screen, and straw puffing machine for corresponding treatment. After drying, cotton stalk fibers with a diameter of 25-85 μm and a length of 2-8 cm are finally obtained for use; the prepared cotton stalk fibers are packed into fixed-weight fiber bags; , The low-melting polylactic acid fiber (PLA) with a length of 2-8cm is transported to the combined opening and cleaning machine for processing, in which the cotton stalk fiber accounts for 75wt% of the total mass of the mixed fiber; The final mixed fibers are combed into a thin fiber web; the thin fiber web is cross-laminated to form a thick new fiber web by using a cross-lapper; 80 thorns / m², made into fluffy flakes, and then use the main needling machine to carry out two main thorns o...

Embodiment 3

[0053] as attached figure 1 As shown, the present invention is a method for preparing biodegradable cotton stalk fiber non-woven fabrics. The collected cotton stalks are sent as a whole to the straw kneading machine, winnowing machine, vibrating screen, and straw puffing machine for corresponding treatment. After drying, cotton stalk fibers with a diameter of 25-85 μm and a length of 2-8 cm are finally obtained for use; the prepared cotton stalk fibers are packed into fixed-weight fiber bags; , The low-melting polylactic acid fiber (PLA) with a length of 2-8cm is transported to the combined opening and cleaning machine for processing, in which the cotton stalk fiber accounts for 85wt% of the total mass of the mixed fiber; The final mixed fibers are combed into a thin fiber web; the thin fiber web is cross-laminated to form a thick new fiber web by using a cross-lapper; 100 thorns / m² to make fluffy flakes, and then use the main needling machine to carry out two main thorns on ...

Abstract

The invention relates to the technical field of non-woven fabric machining methods, in particular to a preparing method of biodegradable cotton stalk fiber non-woven fabric. The method comprises the eight machining steps of cotton stalk fiber preparing, packaging, blended fiber preparing, carding, cross lapping, needling forming, oven baking, and calendaring shaping. Agricultural waste cotton straw is wholly a raw material, natural fiber that is cotton stalk fiber is produced, low-melting-point polylactic acid fiber (PLA) and cotton stalk fiber are mixed and machined, in the machining process,the low-melting-point polylactic acid fiber is melted and is solidified with cotton stalk fiber, and a flexible cotton stalk fiber non-woven fabric finished product is finally obtained and is naturalnon-woven fabric which is low in cost and wide in purpose. Resources are saved, environmental pollution is reduced, the waste is changed into wealth, and the method has the giant economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric processing methods, and relates to a method for preparing biodegradable cotton stalk fiber nonwoven fabrics. Background technique [0002] With the development of the country's economy, the progress of society, and the enhancement of national environmental protection awareness, the country is increasingly advocating the development of high-quality ecological products for enterprises and individuals, encouraging the development of green production processes, and promoting the use of environmentally friendly products. Cotton stalks are the most common by-products of cotton, and are generally discarded as useless. In order to make full use of agricultural waste resources to reduce environmental pollution, and to make up for the shortage of natural fiber resources in my country, the applicant of the present invention has researched and developed for many years Developed a method of producing co...
