Abstract

The invention discloses a processing method for wool short fiber wet felt. The short fiber is first cut into a length of 0.5-20mm; a polyethylene oxide-containing dispersant with a mass percentage of 0.0001%-0.01% is prepared; Fiber suspension, the mass percentage of short fibers is 0.1% to 2%; the pH value of the fiber suspension is adjusted to 2 to 5 by an acidic solution; , filter water, and vacuumize to obtain a fiber wet-laid web; use polyvinyl alcohol to prepare a binder solution with a concentration of 1% to 20%, and spray it on the fiber wet-laid web; then place the fiber wet-laid web at 50 Dry in an oven at ℃ to 120 ℃ for 0.1h to 2.5h, and cool to room temperature to prepare a fiber wet-laid felt. The processing method of the present invention utilizes the wet non-woven technology to process and manufacture the waste short wool fiber, realizes the recycling of the waste short wool fiber resource, and saves the production cost.

Description

technical field [0001] The invention belongs to the technical field of wet non-woven processing, and relates to a processing method of wool short fiber wet felt. Background technique [0002] Wool is an important raw material for the textile industry. It can be used to weave high-grade clothing fabrics, industrial woolen fabrics, felts, cushioning materials and decorations, such as tapestries and carpets. It has good elasticity, strong moisture absorption, good warmth retention, and soft luster. These properties make wool fabrics have various unique styles, and become the object of favor of consumers. my country is a big wool-producing and wool-consuming country. The wool textile processing volume exceeds one-third of the world's total wool. First, it has high impurity content, poor spinnability, and difficult processing. It is generally treated as garbage or waste, causing a lot of waste. [0003] Wet-laid nonwovens are also known as wet-laid nonwovens, and their English n...
