Abstract

The invention discloses a preparation process of imitation bamboo fiber fabric, and the specific preparation process is as follows: in the first step, the antibacterial water-absorbing polymer and polyvinyl alcohol are simultaneously added to the screw extruder according to the mass ratio of 10:0.47-0.55 Carry out melt extruding, obtain spinning polymer; Second step, the spinning polymer prepared in the first step is added in melt spinning machine and carry out melt spinning, obtain fiber silk, then add the fiber silk obtained into 95- Cook in hot water at 100°C for 5-6 hours, then remove, dry in a drying room at 50-60°C to obtain imitation bamboo fibers, and then use the imitation bamboo fibers to prepare imitation bamboo fiber fabrics. The fabric prepared by the invention not only has the properties of bamboo fiber antibacterial and antibacterial, moisture absorption and quick drying, breathable and comfortable, but also has high strength, can withstand repeated cleaning and use, improves the service life, and solves the problem of short service life of existing bamboo fiber fabrics. shortcoming.

Description

technical field [0001] The invention belongs to the field of fabric preparation and relates to a preparation process of imitation bamboo fiber fabric. Background technique [0002] Bamboo fiber is widely used due to its antibacterial, antibacterial, moisture-absorbing, breathable, comfortable and beautiful features. However, bamboo fiber has low toughness and brittle texture. Fabrics made of bamboo fiber are easy to break and cannot be used for a long time. At the same time, with the increase of washing times, the air permeability and instant water absorption of bamboo fiber products gradually decrease. Therefore, in the prior art, bamboo fiber is usually mixed with other functional fibers, but it is easy to cause the overall moisture absorption and breathability of bamboo fiber after mixing. and reduced antibacterial properties. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process of imitation bamboo fiber fabric, wh...
