Problems solved by technology

But the method of oiling agent also has following unfavorable aspects: 1, increased production cost, is reflected in aspects such as the equipment of oiling agent raw material and oiling agent and technology; People's lives and the environment have brought adverse effects; 3. Limiting the application of fibers in some aspects, such as in the fields of medical and hygiene

Embodiment 1

[0062] Set the distance between the action disk of the opening device and the feeding disk and silk outlet disk to be 1cm, the diameter of the feeding hole, action hole, and silk outlet hole to be 5mm, and take 50000dtex seaweed fiber tow, the tow is dried In the unopened state, it has the characteristics of obvious adhesion and stiffness. After passing through the feeding roller, the tow passes through the feeding hole, action hole and silk outlet hole of the device in sequence, and is pulled out by the drafting roller to keep the fiber When the tension is 200g, turn on the tow traction device to keep the tow moving forward at a speed of 10m / min, then start the opening device, and the action disc rotates periodically along a circular track with a diameter of 2cm at a speed of 40 rpm, and the tow After passing through the opening device in sequence, it becomes soft, the adhesion and induration before opening are basically eliminated, and the fibers are well opened.

Embodiment 2

[0064] Adopt an opening device that is arranged in series by two sets of feeding discs, action discs, and silk output discs. Set the distance between the action disc, the feeding disc, and the output disc at 1 cm, and set the holes for the feeding holes, action holes, and output holes. The diameter is 1cm, and the regenerated cellulose fiber tow of 100000dtex is taken. The tow is in an unopened state after drying, and has obvious characteristics of sticking and hardening. The tow passes through the feeding roller and then passes through the feeding device in sequence The entry hole, action hole, and thread exit hole are pulled out by the drafting roller. Keep the fiber tension at 1000g. Turn on the tow pulling device to keep the tow moving forward at a speed of 30m / min. Then start the opening device to move The disc oscillates periodically along a circular trajectory with a diameter of 5cm at a speed of 60 rpm. The tow becomes soft after passing through the opening device in se...

Abstract

The invention discloses a method for opening a multi-hydrogen bond fiber tow, and belongs to the technical field of fiber tow. The method comprises the steps of: selecting an action point or an actionpoint interval of a multi-hydrogen bond fiber tow in the length direction of the multi-hydrogen bond fiber tow; performing a bending operation on the action point in at least three directions in thespace, so that each of the fibers in the multi-hydrogen bond fiber tow moves relative to the surrounded fibers to eliminate adhesion between each fiber and the surrounded fibers. Compared with the currently used oiling agent method, the method for opening the multi-hydrogen bond fiber tow has the following advantages: 1, no small molecule chemical substances are attached to the fiber, thereby saving the auxiliary cost and having the advantages of green and environmental protection; 2, the fiber application field can be directly and conveniently extended to the medical and health fields; 3, theprocess is simple, the operation is convenient, the cost is low, and the application potential is huge.

Description

technical field [0001] The invention relates to the technical field of fiber tows, in particular to a method for opening fiber tows with multiple hydrogen bonds. Background technique [0002] Multi-hydrogen-bonded fibers refer to a type of fiber material that contains hydrogen-bonding groups in the repeating units of the macromolecular structure of the fibers. Naturally regenerated fibers often belong to this category, such as regenerated cellulose fibers, seaweed fibers, and chitin fibers. This kind of fiber often shows a semi-cohesive and stiff state after being directly dried without surface treatment, which is caused by local adhesion between the fiber surfaces. This state of sticking and hardening has brought troubles to subsequent cutting, spinning, weaving, non-woven and other processing and application development. At present, the method to solve this problem is generally to use the method of oiling agent, that is, attach some surfactants and dispersants to the surf...
