Plastic sheeting has broad application in agriculture, in particular, agricultural plastic sheeting. Plastic sheeting recycling is difficult. It had generated the negative impact on environment for the expanding of the plastic sheeting usage and the growing of using years. Some plastic films accumulated in the farmland continuously so it destroyed the soil environment of crops. There are lots of researches about degradable agricultural film in the world.In this topic, the abandoned cotton linter in cotton spinning industry was purified and pulped, followed forming non-woven by papermaking and then the non-woven web was impregnated in liquid paraffin and it was stereotyped by surface sizing, thus obtained a degradable non-woven agricultural film. Force, tearing, the degradation rate, transmission, air, water vapor permeability other performance of the samples were tested, the performance of non-woven cotton linter agricultural film was analyzed.The results indicated that non-woven cotton linter agricultural film compared with the general PE presents better physical properties and degradability and after degradation, it becomes organic fertilizer.In this paper, an important analysis was made through a multi-factor analysis of the pulp cooking process with alkali, Hydrogen peroxide content for bleaching and the amount of cooking aids , it was explored to the process of cooking. It provides a basis for cotton linter cooking technologies and cooking aids preferred to in the future1,Cotton linter plastic film have the following characteristics as mule film:(1)Cotton linter film with high value-added functional products. is a viable way to solve the agricultural"white pollution" produced by plastic film and has a good market prospect(2)Cotton linter film is rich in raw materials.The traditional paper method is simple relatively and easy to promote the use of farmland.(3)Cotton linter film has a good tensile strength, tear strength, wet and dry strength, breathable, moisture permeability, degradation .However, the thickness of Cotton linter film is relatively thicker, and its scalability can be poor, the translucent of film has been definite improvement, but it is poorer than translucent of plastic film.and needs to be done to improve further.2,Cotton linter film have the following characteristics as greenhouse film:Transmittance properties of cotton linter film used as greenhouse film is less than transmittance properties of greenhouse film. the requirements of (transmittance of greenhouse film more than 85%) .the stability of cotton linter is poor. under natural conditions, cotton linter film will degrade Some physical properties of cotton linter film will weakened such as strength etc...
