Production technology of viscose extinction monofilament

Abstract

The invention relates to a production technology of viscose extinction monofilament. The production technology takes cellulosic fiber pulp as a raw material and obtains viscose extinction monofilament through preparation of a spinning solution, injection before spinning, 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) adding a titanium dioxide solution into the spinning solution so that the weight ratio of titanium dioxide to alpha cellulose content in the spinning solution reaches (0.5-5.0):100; and uniformly mixing and feeding for spinning; (C) 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%, and an inlet channel of the spinneret orifice is in a parabola shape; and (D) 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 filament number of the prepared viscose monofilament is 50-6,000D, the strength is high over 75CN, and the requirements on dyeing, weaving and finished product taking are met; and moreover, the viscose extinction monofilament has gentle color and an extinction effect.

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 matte 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] With the improvement of people's living standards, higher requirements have been put forward for the development of fabrics with unique styles. Monofilament was only used in industry and home textile fields in the past. Due to the lower strength of monofilament than multifilament of the same denier, there are greater difficulties in weaving technology and processing technology in the field of weaving, which limits the development of mono...
