Embodiment 1

[0031] A kind of production technology of wool polyester blended smooth wool double-faced woolen, described production technology comprises following process steps:

[0032] The first step: pretreatment of raw materials

[0033] Pretreatment of polyester fiber strips: prepare lipase pretreatment solution, dip the polyester fiber strips into the pretreatment solution and pass them through rolls, two dips and two rolls, and stack the dipped polyester fibers in a 50°C thermostat for 6 hours. Boil at 100°C for 10 minutes, wash once at 60-70°C, and once at 30-40°C; soak the washed polyester fiber strips in a sodium hydroxide solution with a concentration of 0.02g / L for 30 minutes, wash once with water, and dry in the air. dyeing. The lipase treatment conditions are as follows: the dosage of the industrial lipase is 60g / L, the excess rate is 95-100%, and the pH value of the lipase pretreatment solution is 7.

Embodiment 2

[0062] On the basis of embodiment 1, the difference of embodiment 2 and embodiment 1 production process is:

[0063] The first step: pretreatment of raw materials

[0064] Pretreatment of polyester fiber strips: stack the polyester fiber strips after padding in a 50°C incubator for 8 hours; soak the washed polyester fibers in a sodium hydroxide solution with a concentration of 0.03g / L for 20 minutes, and wash them once. Allow to dry ready to stain. The lipase treatment condition is: the consumption of the industrial lipase is 80g / L.

[0065] Pretreatment of wool fibers: stack the padded Australian wool tops and sheep wool tops in a 45°C incubator for 30 minutes, adjust the pH value to 3-4 with acetic acid to kill enzymes, wash once at 60-70°C, and wash once at 30-40°C Wash once with water; the dosage of the protease is 8g / L.

[0066] The second step: weighing and dyeing raw material fibers

[0067] Dyeing process of polyester fiber: use alkali-resistant disperse dyes, the ...

Embodiment 3

[0075] On the basis of embodiment 1, the difference of embodiment 2 and embodiment 1 production process is:

[0076] The first step: pretreatment of raw materials

[0077] Pretreatment of polyester fiber strips: stack the polyester fiber strips after padding in a 60°C thermostat for 10 hours; soak the washed polyester fiber strips in a sodium hydroxide solution with a concentration of 0.04g / L for 20 minutes, and wash them once , dry and ready to dye. The lipase treatment condition is: the consumption of the industrial lipase is 100g / L.

[0078] Pretreatment of wool fibers: stack the padded Australian wool tops and sheep wool tops in a 50°C incubator for 60 minutes, adjust the pH value to 3-4 with acetic acid to kill enzymes, wash once at 60-70°C, and wash at 30-40°C 1 time; the dosage of the protease is 10g / L.

Abstract

The invention provides a production technology of a polyester-wool blended smooth double face woolen cloth. According to the production technology, Australian woolen stripes, woolen stripes of sheep wool, and polyester stripes are preprocessed, dyed, and fully blended, the mixture is spun by an air flow spinning technology to obtain yarns (12.5 / 1); the yarns are woven in a rapier loom; the total number of yarns is 5900-6300; the loaded fabric width is 190 to 200 cm; the portie / yarn number is 35 / 9; the weft density is 285-290 yarns / 10 cm; the fabric weight is 950-1000 g / m2; and the gray fabricsare subjected to following steps: edge seaming, shrinking, washing, dehydrating, drying, steaming, teasel raising, drying, cutting, and steaming. The smooth double face woolen cloth has a stable size, is firm and durable, is resistant to wrinkles, and has an excellent performance on resisting static electricity.

Description

technical field [0001] The invention relates to a woolen cloth and a production process thereof, in particular to a production process of a wool-polyester blended smooth wool double-faced woolen fabric. Background technique [0002] As people pursue leisure and comfortable life trends, wool fabrics are becoming lighter and thinner. In order to meet the durability of fabrics, a certain amount of synthetic fibers needs to be added. Wool and polyester blended fabrics have gradually become the most commonly used fabrics because of their unique style. One of the high-end clothing fabrics. However, wool and polyester blended fabrics are also prone to static electricity and absorb dust. At the same time, fine wool and polyester fiber blends are used, because static electricity will also cause inconvenience in the weaving process. Therefore, it is necessary to improve the antistatic performance of wool and polyester blended fabrics, which is of great significance for the applicatio...
