Abstract

The invention discloses a preparation method of a modified sisal hemp carpet. The sisal hemp carpet is preprocessed with a sodium hydroxide solution and an auxiliary and is modified with metasilicic acid under the promotion action of a coupling agent, and the characteristics of the sisal hemp carpet are improved with the match of an antioxidant, a textile stain and the like. The preparation method overcomes the defects that a sisal hemp fiber is rigid, hard and rough, is not likely to dye, is likely to deform and fade easily at the high temperature, and the modified sisal hemp carpet not only keeps the characteristics of wear resistance, acid and alkali resistance, elasticity and the like, but also has the characteristics of smoothness, environmentally friendliness and high temperature resistance, and low possibility of deforming, fading or aging. The smoothness and the color variety of the modified sisal hemp carpet and the smoothness and the color variety of a traditional cotton carpet are equivalent, and the prominent advantages of corrosion resistance, wear resistance and the like of the modified sisal hemp carpet are more accepted by consumers in comparison with the traditional cotton carpet, and help to promote and popularize the sisal hemp carpet.

Description

technical field [0001] The invention relates to a method for processing plant fibers, in particular to a method for preparing a modified sisal carpet. Background technique [0002] Sisal (scientific name: Agave sisalana Perr. ex Engelm.) also known as pineapple hemp, Agave genus of Agaveaceae, is a perennial tropical hard leaf fiber crop, which originated in Mexico and is now mainly planted in Africa, Latin America, Asia and other places. It is a hard fiber with the largest amount and the widest range in the world today. Sisal fiber is tough, wear-resistant, salt-alkali-resistant, and corrosion-resistant. It is widely used in various industries such as transportation, fishery, petroleum, and metallurgy, and has important economic value. Sisal carpets made of sisal fibers are more common in daily life and are becoming more and more popular. The color and style of sisal carpet are relatively simple, suitable for various styles of home decoration. It is a carpet material wi...
