Embodiment 1

[0029] A new process for the production of viscose flat monofilaments. The spinning solution made from cellulose fiber pulp is sprayed out through the spinneret to form a viscose fiber film with a width of 1.5m, which is drawn into the coagulation bath, In the post-processing area and drying area, after drying, the fiber film is cut into viscose flat monofilaments with a width of 5 mm, and the finished product is wound after cutting.

Embodiment 2

[0031] A new process for the production of viscose flat monofilaments. The spinning solution made from cellulose fiber pulp is sprayed out through the spinneret to produce a 4.5m wide viscose fiber film, which is drawn into the coagulation bath, In the post-processing area and drying area, after drying, the fiber film is cut into viscose flat monofilaments with a width of 60mm, and the finished product is wound after cutting.

[0032] The spinneret is composed of upper and lower spray plates, and the gap between the upper and lower spray plates is 0.05mm.

[0033] The cellulose pulp of the present invention includes cotton pulp, wood pulp and bamboo pulp.

[0034] The viscose flat monofilament made by the new process of viscose flat monofilament production of the present invention has a dry breaking strength of 1.5-2.0CN / dtex, a wet breaking strength of 1.0-1.5CN / dtex, and a dry breaking elongation of 15- 20%.

Embodiment 3

[0036] A new process for the production of viscose flat monofilaments. The spinning solution made from cellulose fiber pulp is sprayed out through the spinneret to form a 2m wide viscose fiber film, which is drawn into the coagulation bath by drafting rollers, and then In the processing area and drying area, after drying, the fiber film is cut into viscose flat monofilaments with a width of 25mm, and the finished product is wound after cutting.

[0037] The spinneret is composed of upper and lower spray plates, the gap between the upper and lower spray plates is 0.5mm, and the upper and lower spray plates are provided with screw holes.

Abstract

In order to solve the problem that the processes of viscose flat monofilaments are complex, the invention provides a new technology for producing the viscose flat monofilaments. The new technology for producing the viscose flat monofilaments is characterized in that cellulosic fiber pulp is used as the raw material to manufacture a spinning solution, a viscose fiber membrane with the width of 1.5-4.5m is ejected through a spinneret plate, the viscose fiber membrane enters coagulating bath, a postprocessing area and a drying area through a drafting roller, and after the viscose fiber membrane is dried, the viscose fiber membrane is cut into the viscose flat monofilaments with the thickness of 5-60mm. After cutting is finished, the finished viscose flat monofilaments are obtained by winding. The new technology is short in process, operation is convenient, the yield is high, and the quality of products is easy to control.

Description

technical field [0001] The invention relates to the technical field of viscose in the textile industry, in particular to a new process for producing viscose flat monofilament. Background technique [0002] Monofilament refers to a single filament produced by a single-hole spinneret in chemical fiber production, and its fineness is in the range of 50D-6000D. Monofilament is widely used in weaving, handmade accessories, home textiles and industrial supplies. The textile quality made of monofilament is thin, transparent and feels good. [0003] Flat yarn is a new type of Vicat fiber with a flat cross-section that is spun by a special process. It combines the excellent properties of ordinary Vicat fiber and hemp fiber. The fabric is smooth, elastic and soft, rich in three-dimensionality, comfortable and pleasant; it has the characteristics of moisture absorption and heat dissipation, and is easier to dye. [0004] For example, 201310119017.4, an invention patent application t...
