Problems solved by technology

It mainly uses oil or liquefied gas singeing machine to singeing, and padding softener is soft to meet product requirements. This technology has many shortcomings for hemp products: ①The nozzle is easy to block when singeing, which is easy to cause streaks Uneven singeing; ②High consumption of water, electricity, and steam resources; ③Severe pollution of surface water system and air by waste water and waste gas; ④Great fiber strength damage; ⑤Large amount of softener and poor softening effect; ⑥Poor dimensional stability of finished products

Embodiment 1

[0019] A bio-enzyme post-finishing process for hemp yarn and hemp-like fabrics, using an overflow dyeing machine with a bath ratio of 1:6 for bio-enzyme post-finishing treatment:

[0020] (1) Low-temperature neutral compound enzyme singeing: put the compound enzyme ingredients in the material tank, turn on the stirring device to mix the compound enzyme ingredients evenly, control the pH value of the compound enzyme ingredients to 6.5, and then heat up to 50°C to obtain a solution, Utilize a stretcher with a lower width of 160cm, control the overfeed amount to 1%, and the cloth speed to 90m / min, put the to-be-processed hemp yarn and hemp cloth into the solution, keep the cloth below the liquid level, and keep warm for 30 minutes;

[0021] (2) Softening with low-temperature neutral compound enzyme: put the soft ingredients in the material tank, turn on the stirring device to mix the soft ingredients evenly, control the pH value of the soft ingredients to 6.5, then introduce the s...

Embodiment 2

[0026] A bio-enzyme post-finishing process for hemp yarn and hemp-like fabrics, using a continuous long-vehicle production line for bio-enzyme post-finishing treatment:

[0027] (1) Low-temperature neutral compound enzyme singeing: add the compound enzyme ingredients in the automatic feeder, then add the compound enzyme ingredients into the two tanks, control the pH of the compound enzyme ingredients to be 8.0, and then heat up to 60°C to obtain solution, using a stretcher with a lower frame width of 170cm, controlling the overfeed amount to 3%, and the cloth speed to 110m / min, put the hemp yarn and hemp cloth to be processed into the solution, keep the cloth below the liquid level, and keep warm 60min;

[0028] (2) Softening with low-temperature neutral compound enzyme: add soft ingredients into the automatic feeding device, then add the soft ingredients into two tanks, control the pH value of the soft ingredients to 8.0, and then raise the temperature to 60°C to obtain a sol...

Embodiment 3

[0032] A bio-enzyme post-finishing process for hemp yarn and hemp-like fabrics, using a continuous long-vehicle production line for bio-enzyme post-finishing treatment:

[0033] (1) Low-temperature neutral compound enzyme singeing: add compound enzyme ingredients into the tank of the long car production line, then add the compound enzyme ingredients into the two tanks, control the pH value of the ingredients to 7.0, and then raise the temperature to 50°C to obtain a solution , using a stretcher with a lower frame width of 165cm, control the overfeeding amount to 2%, and the cloth speed to 100m / min, put the to-be-processed hemp yarn and hemp cloth into the solution, keep the cloth below the liquid level, and keep it warm for 40 minutes ;

[0034] (2) Softening with low-temperature neutral compound enzyme: add soft ingredients into the automatic feeding device, then add the soft ingredients into the two tanks, control the pH value of the soft ingredients to 7.0, and then raise t...

Abstract

The invention relates to a process for after-finishing biological enzymes of ramie yarn and bast fiber cloth. The process comprises the following steps of: (1) placing a composite enzyme ingredient in a material cylinder, controlling the pH value, raising the temperature to 50 to 60 DEG C and running the cloth under a liquid level for 30 to 60 minutes; (2) guiding the solution to a main cylinder,controlling the pH value, raising the temperature to 50 to 60 DEG C, running the cloth under the liquid level for 30 to 60 minutes, raising the temperature to 70 to 85 DEG C and running the cloth under the liquid level for 10 to 20 minutes; and (3) placing a film-forming ingredient in the main cylinder, controlling the pH value, raising the temperature to 50 to 60 DEG C to obtain the solution andrunning the cloth under the liquid level for 30 to 60 minutes. Compared with the prior art, the process for after-finishing the biological enzymes of the ramie yarn and the bast fiber cloth saves energy consumption, simplifies a technological process, prevents the production of toxic substances, remarkably enhances the product quality, achieves a top-quality product rate of over 98 percent and greatly reduces the production cost.

Description

technical field [0001] The invention relates to a post-finishing process, in particular to a bio-enzyme post-finishing process for hemp yarn and hemp cloth. Background technique [0002] The existing finishing process of linen yarn or linen gray cloth is: singeing→washing→softening→expanding→drying→preshrinking. It mainly uses oil or liquefied gas singeing machine to singeing, and padding softener is soft to meet product requirements. This technology has many shortcomings for hemp products: ①The nozzle is easy to block when singeing, which is easy to cause streaks Uneven singeing; ②High consumption of water, electricity, and steam resources; ③Severe pollution of surface water system and air by waste water and waste gas; ④Great fiber strength damage; ⑤Large amount of softener and poor softening effect; ⑥Poor dimensional stability of finished products . Contents of the invention [0003] The object of the present invention is to provide an energy-saving, water-saving and s...
