Problems solved by technology

[0006] The present invention proceeds from the mechanism of ramie fabric prickling sensation, aiming at that conventional cellulase anti-itch feeling finishing is easy to cause serious strength loss and anti-itch feeling effect on ramie fabrics is not significant, simple polyurethane finishing can improve ramie texture by coating hairiness and improving ramie texture. The elasticity of the fiber can be used to reduce the itching, but it cannot directly reduce the rigidity of the ramie fiber. Consider combining the two methods to finish the ramie fabric, so as to reduce the itching of the fabric while maintaining the original properties of the ramie fabric.

Embodiment 1

[0031] In this example, cellulase 80L and water-based polyurethane finishing agent PA-11 were used to jointly finish the ramie fabric. The specific operation steps are as follows:

[0032] (1) Cellulase finishing of ramie fabric

[0033] Finishing solution formula: 80L cellulase dosage is 1.0% (o.w.f.), bath ratio is 1:30.

[0034] Finishing process: configure a buffer solution with a pH of 4.5, bathe the fabric at room temperature, add cellulase when the temperature rises to 55°C, keep warm for 90 minutes, take the fabric out and treat it in hot water at 100°C for 10 minutes to make the fibers Sulfase is completely inactivated, take it out, wash it with water, and dry it in the air.

[0035] (2) Polyurethane finishing of ramie fabric

[0036] Finishing liquid formula: the dosage of polyurethane finishing agent PA-11 is 40g / L.

[0037] Finishing process: the fabric after the cellulase finishing in step (1) is dipped twice in the polyurethane finishing solution at room temp...

Embodiment 2

[0039] In this example, cellulase 80L and water-based polyurethane finishing agent PA-11 were used to jointly finish the ramie fabric. The specific operation steps are as follows:

[0040] (1) Cellulase finishing of ramie fabric: same example one.

[0041] (2) Polyurethane finishing of ramie fabric

[0042] Finishing solution formula: the dosage of polyurethane finishing agent PA-11 is 140g / L.

[0043] Finishing process: the fabric after cellulase finishing in step (1) is dipped twice in polyurethane finishing solution at room temperature, the liquid retention rate is 100%, pre-baked at 80°C for 3 minutes, and then heated at 150°C Bake at ambient for 6 minutes.

Embodiment 3

[0045] In this example, cellulase 80L and water-based polyurethane finishing agent PA-11 were used to jointly finish the ramie fabric. The specific operation steps are as follows:

[0046] (1) Cellulase finishing of ramie fabric: same example one.

[0047] (2) Polyurethane finishing of ramie fabric

[0048] Finishing liquid formula: the dosage of polyurethane finishing agent PA-11 is 200g / L.

[0049]Finishing process: the fabric after cellulase finishing in step (1) is dipped twice in polyurethane finishing solution at room temperature, and the liquid retention rate is 98%, pre-baked at 75°C for 4 minutes, and then heated at 180°C Bake at ambient for 5 minutes.

Abstract

The invention relates to an anti-itchy finishing method for a ramie fabric treated by using a united finishing method comprising the following steps of: firstly, carrying out proper dipping treatment on the ramie fabric by using cellulose enzyme treating fluid with the concentration of 1.0-3.0% (o.w.f), and then, carrying out padding or dipping treatment on the ramie fabric by using aqueous polyurethane treating fluid with the concentration of 40-200g / L. The anti-itchy finishing method for the ramie fabric has the beneficial effect that the finishing the ramie fabric by using cellulose enzyme is beneficial to the reduction of fibers crystallinity to achieve the aim of lowering the rigidity and be beneficial to the lowering of the itchy sensation of the fabric; and an elastic polyurethane finishing agent for the ramie fabric can be used for not only covering fuzzy yarns on the surface of the fabric, but also playing a role in enhancing the elasticity of fibers. Particularly, the organization structure of the fabric finished by using the cellulose enzyme becomes more loosen and active after the two optimized processes are united to treating the ramie fabric; in addition, the surfaces of the fibers generate an etching function which is beneficial to the permeation of the elastic polyurethane finishing fluid inside the fibers, so that the elasticity of the fibers is better improved, and furthermore, the aims of reducing the itchy sensation of the ramie fabric and improving the wearability are achieved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and mainly relates to an anti-itch finishing method for ramie fabrics. Background technique [0002] Ramie is a unique crop in my country that mainly uses textiles, and its output and processing capacity rank first in the world. Compared with cotton fabric, ramie fabric has better air permeability, moisture dissipation, stiffness and antibacterial properties. It not only conforms to the trend of contemporary people's environmental protection, but also conforms to the concept of "advocating nature" in today's world. It has broad application and development prospects. However, due to the high degree of crystallinity and orientation of ramie fiber, the appearance of the fiber is straight and rough, the elasticity is poor, the elongation at break is low, the extensibility is small, and the spinnability is poor, so that the fabric is easy to fluff and wrinkle, and the yarn and clo...
