Production technology of viscose flat monofilament

Abstract

The invention relates to a production technology of viscose flat monofilament. The production technology takes cellulosic fiber pulp as a raw material and obtains viscose monofilament with the flatness of (10-500):1 through preparation of a spinning solution, spinning and aftertreatment, and specifically comprises the following steps of: (A) preparing the spinning solution from the cellulosic fiber pulp through steeping, ageing, yellowing, dissolving, defoaming and filtering; (B) feeding the spinning solution into a spinning machine and enabling the spinning solution to pass through a spinneret orifice of a single-hole spray head under pressure, and solidifying and molding the formed viscose trickle to form raw silk strips, wherein the spray head is stretched by +60% to +80%, an inlet channel of the spinneret orifice is in a parabola shape, the shape of the spinneret orifice is '-', 'C' and 'S', and the length-width ratio of the spinneret orifice is (100-1,500):1; and (C) performing aftertreatment: performing desulfurization, bleaching, oiling and drying on the raw silk strips to obtain the viscose flat monofilament. According to the production technology provided by the invention, the cross section of the prepared viscose flat monofilament strip is in a flat shape, and the viscose flat monofilament has an effect of natural hemp fiber and can be widely applied to weaving.

Description

technical field

[0001] The invention relates to the technical field of viscose in the textile industry, in particular to a production process of 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.
