Embodiment 1

[0022] Step 1: Humidification: According to the mass ratio of 1:2, spray and add water to the natural cellulose fiber of cotton stalk bark, and let it suffocate for 8 hours.

[0023] Step 2: Roller carding: the humidified and stuffed natural cellulose fiber of cotton stalks is carded twice in a roller carding machine. The distance between cylinder and work roller is 0.7mm, and the distance between cylinder and doffer is 0.5mm. The cylinder-work roll speed ratio is 15:1.

[0024] Step 3: Flat carding: the cotton stalk bark cellulose fibers combed by rollers are then carded once on a flat carding machine. The distance between cylinder and cover plate is 0.3mm, and the distance between cylinder and doffer is 0.2mm. Cylinder speed 500r / min.

Embodiment 2

[0026] Step 1: Humidification: According to the mass ratio of 1:3, spray and add water to the natural cellulose fiber of cotton stalk bark, and let it suffocate for 12 hours.

[0027] Step 2: Roller carding: the humidified and stuffed natural cellulose fiber of cotton stalks is carded once in a roller carding machine. The distance between cylinder and work roller is 0.4mm, and the distance between cylinder and doffer is 0.3mm. The cylinder-work roll speed ratio is 20:1.

[0028] Step 3: Flat carding: the cotton stalk bark cellulose fibers combed by rollers are then carded twice on a flat carding machine. The distance between cylinder and cover plate is 0.4mm, and the distance between cylinder and doffer is 0.13mm. The cylinder speed is 400r / min.

Embodiment 3

[0030] Step 1: Humidification: According to the mass ratio of 1:5, spray and add water to the natural cellulose fiber of cotton stalk bark, and let it suffocate for 12 hours.

[0031] Step 2: Roller carding: the humidified and stuffed natural cellulose fiber of the cotton stalk bark is carded 3 times in a roller carding machine. The distance between cylinder and work roller is 0.9mm, and the distance between cylinder and doffer is 0.6mm. The cylinder-work roll speed ratio is 10:1.

[0032] Step 3: Flat carding: the cotton stalk bark cellulose fibers combed by rollers are then carded once on a flat carding machine. The distance between cylinder and cover plate is 0.15mm, and the distance between cylinder and doffer is 0.13mm. The cylinder speed is 450r / min.

Abstract

The invention discloses a cotton bast cellulose fiber length and fineness homogenizing method, which comprises the following steps of: wetting, namely spraying water onto cotton bast cellulose fibers in a mass ratio of the cotton bast cellulose fibers to the water of 1:1-1:5, and sealing and standing for 8 to 12 hours; carding the cotton bast cellulose fibers which are wetted, sealed and stood by using a roller and clearer card for 1 to 3 times; and carding the cotton bast cellulose fibers subjected to roller carding by using a top card to homogenize the length and fineness of the cotton bast cellulose fibers. By the cotton bast cellulose fiber length and fineness homogenizing method, the obtained homogenized cotton bast cellulose fibers have low length and fineness dispersion, and a problem of high difficulty in spinning the cotton bast cellulose fibers is solved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a method for processing natural cellulose of cotton stalk husks, in particular to a method for uniformizing the length and fineness of cotton stalk husk cellulose fibers. Background technique [0002] The shortage of raw material resources and high international dependence of my country's textile industry have become the main contradictions in the development of the textile industry. Vigorously developing all kinds of natural fiber raw material resources has become an important task for the textile industry to adjust the resource structure. The use of cotton stalk husks to prepare natural cellulose has been successful, but as a technical fiber, cotton stalk husk cellulose fibers have great discreteness in length and fineness, making textile processing difficult. For this reason, the present invention carries out length and fineness homogenization treatment to natural cellulose fi...
