A treatment for increasing the curl of natural wool

Abstract

The invention discloses a treatment method for increasing the crimping degree of natural wool. The treatment method comprises the following steps of: (1) carrying out bio-enzyme preparation treatment on the natural wool, namely firstly, treating impurity-removed and carbonized wool fibers with a bio-enzyme preparation, treating with a keratinase and protease one-bath process, inactivating enzymes at a high temperature, washing and drying at 50 DEG C; (2) carrying out crimping and warm-keeping treatment on the natural wool subjected to the bio-enzyme preparation treatment, wherein the crimping and warm-keeping treatment temperature is controlled within 50-60 DEG C and the treatment time is controlled within 20min-40min; (3) carrying out fluffy softening treatment on the natural wool subjected to the crimping and warm-keeping treatment, wherein the crimping and warm-keeping treatment temperature is controlled within 50-60 DEG C and the treatment time is controlled within 15min-30min; and (4) finally, carding the natural wool subjected to the fluffy softening treatment into waddings, and spraying and drying, wherein the waddings are dried for 2min at the temperature of 130 DEG C. According to the treatment method disclosed by the invention, the wool is subjected to pre-treatment with the bio-enzyme preparation and manual crimping treatment with a chemical auxiliary agent, so that the crimping degree of the wool is greatly increased, and the fluffiness and warm-keeping property of the wool are improved.

Description

technical field [0001] The invention relates to a method for treating the curl degree of wool, in particular to a method for increasing the curl degree of natural wool. Background technique [0002] Because curly wool contains a lot of air; and the heat transfer rate of air is very low, which can effectively prevent the entry of external cold air and the emission of internal hot air, so the wool quilt has good natural thermal insulation performance. But the surface layer of wool is the scale layer, and each of its corrugated or fish-like scales is connected to the cortex at one end of the hair root, and the other end is stretched outward, covering and connecting piece by piece. Since the scale layer is stretched outward and protrudes, if the friction between the fibers is increased, they will be restrained each other to produce felting and hardening. Therefore, due to the fact that wool quilts are easy to harden during use, and with the emergence of down and some thermal fi...

Problems solved by technology

Therefore, due to the fact that wool quilts are easy to harden during use, and with the emergence of down and some thermal fibers, the thermal performance of wool does not have a very good competitive advantage. In recent years, the market acceptance of wool quilts is not high.

In recent years, there have been more and more studies on wool quilts. Some research institutions have improved the properties of wool by modifying raw wool. Li Hengjiang and others have improved the performance of wool quilts by compounding wool with other fibers to make quilts. But all of them only improve the feel of the wool quilt, and cannot fundamentally improve the bulkiness and warmth retention of wool

[0003] Compared with down and various new thermal fibers, the thermal performance of wool products does not have a very good competitive advantage. At the same time, because wool quilts are easy to harden during use, the market acceptance of wool quilts has not been high in recent years.
