Problems solved by technology

Among them, the chlorination / resin two-step method pollutes a lot, and the wool fabric treated by this method is easy to yellow and darken in color, resulting in poor appearance of fabric and clothing and reducing the grade of textiles; although protease treatment can solve the problem to a certain extent The above problems will reduce the strength of the fabric, and subsequent reinforcement treatment is required, and the process is long; at present, relatively new plasma treatment methods, liquid ammonia treatment methods, ozone gas treatment methods and nanomaterial treatment methods are relatively expensive.

Embodiment 1

[0027] Wool yarn specifications: 66s Australian wool, spun into 54 counts / 2 strands of yarn

[0028] Put 20g of the above-mentioned wool yarn in a beaker with a concentration of hydrogen peroxide solution of 6g / L, a sodium silicate solution of 4g / L, a temperature of 40°C, and a bath ratio of solution to wool of 20:1. After stirring and soaking for 20 minutes, take out the fabric Rinse with clear water, and then the fabric is padded with a mixed solution of silk fibroin and chitosan (two dips and two pads, the pass ratio is 70%-80%), wherein, silk fibroin finishing agent SP1 10g / L, chitosan solution 7g / L L, then pre-baked at 80°C for 2min, baked at 120°C for 1min, washed with water at 80°C, softened with 0.5g softener, dehydrated and woven. The test results are shown in Table 1.

Embodiment 2

[0033] Wool yarn specifications: 66s Australian wool tops, spun into 48 counts / 2 strands of yarn

[0034] Put 20g of the above-mentioned wool tops in a beaker with a concentration of hydrogen peroxide solution of 6g / L, a sodium silicate solution of 4g / L, a temperature of 45°C, and a bath ratio of the solution to wool of 15:1. After stirring and soaking for 20 minutes, take out the fabric Rinse with clear water, and then the fabric is padded with a mixed solution of silk fibroin and chitosan (two dips and two pads, the pass ratio is 70%-80%), wherein, silk fibroin finishing agent SP1 10g / L, chitosan solution 7g / L L, then pre-baked at 80°C for 3min, baked at 120°C for 2min, washed with water at 80°C, softened with 0.4g softener, dehydrated and woven. The test results are shown in Table 2.

Embodiment 3

[0038] Specifications of wool and nitrile blended yarn: wool / nitrile ratio is 7 / 3, spun into 36 counts / share yarn

[0039] Put 20g of the above-mentioned wool tops in a beaker with a concentration of hydrogen peroxide solution of 6g / L and a sodium silicate solution of 4g / L at a temperature of 50°C. The bath ratio of the solution to wool is 20:1. After stirring and soaking for 20 minutes, take out the fabric Rinse with clear water, then the fabric is padded with silk fibroin and chitosan mixed solution (two dips and two pads, the remaining rate is 80%), wherein, silk fibroin finishing agent SP1 10g / L, chitosan solution 7g / L, after that Pre-baked at 80°C for 3 minutes, baked at 120°C for 3 minutes, washed with water at 80°C, softened with 0.2g softener, dehydrated and woven. The test results are shown in Table 3.

Abstract

The invention discloses an ecological anti-felting finishing method for wools. The pretreatment adopts hydrogen peroxide pretreatment; and by padding the wools into mixed finishing solution of fibroin finishing agent SP1 and chitosan with certain concentration, the anti-felting rate of the treated wool fabrics is less than 3 percent, the strength is increased by about 6 percent, the whiteness is changed little, the air permeability of the wool fabrics is superior to that of the primary fabrics, the elongation at break is reduced, the water absorption is increased, the handfeel is soft, the anti-pilling property of the wool fibers is improved by 2 to 3 levels, and the wool fabrics can fully meet the requirement of machine wash. The method comprehensively adopts the environment-friendly finishing agent to perform anti-felting finishing for the wools, has no residues of harmful substances, does not cause environment pollution, simplifies the treatment process, shortens the process flow, has shorter period, and improves the feasibility of industrialized operation.

Description

technical field [0001] The invention relates to silk fibroin and chitosan anti-felting finishing technology for wool and its textiles, in particular to an ecological anti-felting finishing method for wool. Background technique [0002] As a natural fiber, wool has many excellent properties that other fibers cannot match, such as: soft, elastic, natural and soft luster, good hygroscopicity, warmth retention, wrinkle resistance and stain resistance. It is suitable for making various clothes and is deeply loved by consumers. However, due to the scale structure on the surface of the wool fiber, the wool fabric has a tendency to feel and shrink under the conditions of humidity, heat and external force, and the area is reduced, which greatly affects the style and dimensional stability of the wool fabric. It is limited that wool fabric clothes cannot be washed with water conveniently, which increases the burden on consumers when taking them. With the change of international fashi...
