Problems solved by technology

However, the anti-shrinkage effect of wool treated with protease alone cannot meet the actual needs at present, so when many adopt protease to carry out biological modification of wool, it is necessary to pre-treat the wool first (such as using strong oxidant permanganate Potassium, etc., or pretreatment with chloride solvents)
The above pretreatment methods all have shortcomings such as long treatment time, easy inactivation of enzymes, and difficult control of treatment conditions.
[0005] In addition, although some researchers try to develop a chlorine-free anti-shrinkage treatment process for wool raw mate

Embodiment 1

[0222] In this embodiment, the continuous process of five-fold padding is adopted to carry out chlorine-free anti-shrinkage treatment on the wool strips.

[0223] The whole wool wool strips to be processed, the specification is 70 pieces. The process includes the following steps:

[0224] The first tank: padding treatment solution. The tank is 1 meter wide, 360 liters in volume and has a suction drum (type) washing tank (universal device) with a circumference of 1 meter. There is an automatic heating device (general device) in the suction drum tank, and the main components are: Alkali protease (alkali protease) 3g / L, three (3-hydroxypropyl) phosphine 3g / L (add non-ionic surfactant JFC 1g / L) efficient catalytic solution, pH is 7.2 (with disodium hydrogen phosphate and Sodium dihydrogen phosphate is a pH regulator), and the temperature is controlled at 50°C.

[0225] Lay the wool strips side by side evenly on the top rollers and enter the treatment liquid at a constant speed ...

Embodiment 2

[0241] In this example, a six-fold padding continuous process is used to perform chlorine-free anti-shrinkage treatment on the wool strips.

[0242] The whole wool wool strips to be processed, the specification is 56 pieces. The process includes the following steps:

[0243] The first tank: padding treatment solution. The tank is a suction drum tank with a width of 1 meter, a volume of 360 liters, and a circumference of one meter. There is an automatic heating device in the suction drum tank, and a liquid containing alkaline protease 3g / L, three (3-hydroxypropyl ) a high-efficiency catalytic solution of 3 g / L of phosphine, the pH is 7.4, and the controlled temperature is 50° C.

[0244] Spread the wool tops evenly on the top rollers side by side and enter the treatment solution at a constant speed of 3.8 m / min to completely wet the wool tops to ensure that the surface of each fiber in the wool tops is treated evenly and thoroughly; then pressurize The rollers pressurize the...

Embodiment 3

[0260] In this embodiment, the continuous process of five-fold padding is adopted to carry out chlorine-free anti-shrinkage treatment on the wool strips.

[0261] All wool wool strips to be processed, the specification is 90 counts. The process includes the following steps:

[0262] The first tank: padding treatment solution. The tank is a suction drum tank with a width of 1 meter, a volume of 360 liters and a circumference of one meter. There is an automatic heating device in the suction drum tank, and alkaline protease 3g / L, tris(3-carboxypropyl) Phosphine 3g / L, anhydrous calcium chloride 0.3g / L (adding non-ionic surfactant JFC 1g / L) high-efficiency catalytic solution, pH is 7.6 (regulate pH with appropriate amount of sodium carbonate or sodium hydroxide solution), control The temperature is 50°C.

[0263] Spread the wool tops evenly on the top rollers side by side and enter the treatment solution at a constant speed of 3.8 m / min to completely wet the wool tops to ensure ...

Abstract

The invention relates to equipment for non-shrink treatment of wool raw materials and products. Specifically, the equipment comprises a multiple padding device, a washing device, an enzyme inactivation device, an optional softness treatment device and an optional dryer, wherein the multiple padding device comprises n independent padding devices arranged continuously, each padding device comprises a soaking tank and a roller, and n is a positive integer ranging from 2 to 20; the washing device is used for washing padded wool tops or wool products, and washed wool tops or wool products are formed. The equipment further comprises transmission devices located between the padding devices and non-shrink treatment liquid supplementing devices located obliquely above the downstream parts of the transmission devices. The equipment can meet the requirement for non-shrink processing treatment of wool tops and wool products, is environmentally friendly, can achieve continuous operation, has the advantages of uniform treatment and high efficiency and is quite suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of wool product processing, in particular to equipment for shrink-proof treatment of wool raw materials and products. Background technique [0002] Wool is an important raw material for the textile industry. It has many excellent properties, such as good elasticity, strong hygroscopicity, not easy to stain, good warmth retention, and soft luster. As a natural protein fiber, wool has a layer of overlapping fish scales mainly composed of keratin on the surface. Due to the different friction coefficients in the forward and reverse directions of the scales, the wool fibers will intersect each other under repeated external forces. Entanglement, cross-knitting, and felting produce fluffing. Although milling makes the wool fabric have beautiful appearance, rich and soft hand feeling, and good thermal performance, it also makes the wool fabric prone to shrinkage and deformation during washing. Therefore, in order to improve...
