Problems solved by technology

[0002] In recent years, with the enhancement of people's awareness of environmental protection and the improvement of the quality of life related to clothing, spinning, clothing fabrics and garments made of environmentally friendly materials have received extensive attention and development in the industry. Polylactic acid fiber, bamboo charcoal Fiber and other environmentally friendly fibers are currently being actively researched and applied in the field of textiles and clothing, but at present this type of material focuses on the environmental protection characteristics of the product, and the properties of the final product of its production process are not much different from traditional textiles, such as Chinese patents CN103266498A, CN203168107U The final products of the announced degradable fabrics or textiles made of polylactic acid as raw materials are still conventional textiles. For bio-based resins such as polylactic acid, it is easier to make fabrics that meet high hygiene standards and use them as a Upstream raw material manufacturing has high hygienic standards, food-grade cleanliness, and special-purpose textile products, but such fabric products have not been reported so far

Embodiment 1

[0017] Food-grade hygienic knitted double-sided fabric made of pure polylactic acid, the specific process is:

[0018] 1) Spin the pure polylactic acid resin and adopt the conventional spinning process.

[0019] 2) Under the hygienic standard environment of food processing grade, the silk is spun by conventional spinning process.

[0020] 3) In the environment of food processing grade hygienic standards, double-sided fabrics are made by knitting.

[0021] 4) The obtained double-sided cloth is subjected to ultraviolet disinfection and superheated steam sterilization.

[0022] 5) Obtain polylactic acid double-sided cloth that finally meets food-grade hygiene standards.

Embodiment 2

[0024] The food-grade hygienic standard blended woven corduroy fabric prepared by using modified polylactic acid and cotton, the specific process is as follows:

[0025] 1) Under the hygienic standard environment of food processing grade, the modified polylactic acid resin is spun, and the conventional spinning process is adopted.

[0026] 2) Using the conventional spinning process, polylactic acid spinning and cotton spinning are used, and the blending ratio of the two is 30:70.

[0027] 3) Under the hygienic standard environment of food processing grade, the corduroy cloth is made by weaving.

[0028] 4) The obtained double-sided cloth is subjected to ozone disinfection and pasteurization treatment.

[0029] 5) Obtain polylactic acid cotton blended corduroy fabric that finally meets food-grade hygiene standards.

Embodiment 3

[0031] The food-grade hygienic standard non-woven fabric prepared by amino acid modified polylactic acid and bamboo charcoal fiber, the specific process is as follows:

[0032] 1) Under the hygienic standard environment of food processing level, the amino acid modified polylactic acid resin is spun, and the conventional spinning process is adopted.

[0033] 2) Under the hygienic standard environment of food processing level, the amino acid modified polylactic acid fiber and bamboo charcoal fiber with a ratio of 80:20 were prepared into non-woven fabrics by using conventional non-woven fabric technology.

[0034] 3) The obtained non-woven fabric is subjected to ultraviolet disinfection and ultra-high temperature instantaneous sterilization (UHT) treatment.

[0035] 4) Obtain the polylactic acid bamboo charcoal fiber blended non-woven fabric that finally meets the food-grade hygienic standard.

Abstract

The invention provides an environment-friendly degradable fiber fabric meeting the food-grade hygienic standards. The environment-friendly degradable fiber fabric meeting the food-grade hygienic standards is prepared and woven from polylactic acid; polylactic acid fibers are taken as a basic material, and according to the hygienic standards of food production, the textile fabric meeting high hygienic standards and high food-grade cleanness is produced; and the textile fabric can be applied to producing textile products for a special purpose. Specifically, the food-grade pure polylactic acid or modified polylactic acid resin is applied independently or blended with common fibers under the hygienic conditions conforming to the international standard GB 14881-1994 or GB 16330-1996 requirements, and a spinning-yarn spinning-weaving process is performed; during the process, a food sterilization process is adopted, and the final fabric product can be obtained; and the obtained fabric product can be further applied to producing textile and clothes products having high requirements on the hygienic conditions, and also has a degradable environment-friendly characteristic.
