Problems solved by technology

[0002] At present, the quality of the inner and outer layers of semi-continuous neutral spun viscose filament cakes in China, such as fineness, linear density deviation rate, linear density CV value, dyeing uniformity, etc., has always been quite different, which affects the quality of viscose filament products. Continuous improvement cannot meet the market's demand for reducing the quality difference between the inner and outer layers of the silk cake to weave high-end products

Embodiment 1

[0016] Embodiment 1 The manufacture method of high-performance homogeneous wood pulp viscose filament

[0017] Taking 75D81m / min and setting the total spinning time as 66300 s as an example, the spinning dope produced by conventional technology is transported to the pre-spinning process. The pre-spinning glue index: viscosity 30-34 s, maturity 10ml.

[0018] The glue is supplied by the metering pump, and the glue supply is 6.22ml / min. On this basis, the glue supply of the metering pump is compensated by -0.5-5.6% in 8 time periods; The concentration of the acid bath is 128-131g / l, using a single ingot to feed and return acid, to control the amount of acid entering and returning, to reduce the acid bath drop and acid bath temperature difference between ingots, ingots, distinctions and distinctions, and between machines. Make the drop of acid bath ≤2g / l, and control the temperature difference of acid bath at 50±0.5°C; It is also divided into the same 8 time periods, and the spe...

Embodiment 2

[0020] The manufacture method of embodiment 2 high-performance homogeneous cotton paddle viscose filament

[0021] Taking 120D89.9m / min and setting the total spinning time as 36900S as an example, the spinning dope produced by conventional technology is transported to the pre-spinning process. The pre-spinning glue index: viscosity 30-34S, maturity 10ml.

[0022] The glue is supplied by the metering pump, and the glue supply is 10.78ml / min. On this basis, the glue supply of the metering pump is compensated by -1-8% in 6 time periods; bath, the acid bath concentration is

Abstract

A method for manufacturing high-performance homogeneous viscose filaments and its products, using wood pulp, cotton pulp or bamboo pulp, etc. The amount of glue is compensated by -1-8%, and the speed of the coagulation roller and the speed of the acid removal roller are compensated by 0-10%. Controlled at 50±0.5°C, the linear density deviation rate of the inner, middle and outer layers of the silk cake is ≤1%, and the linear density CV value is ≤1%. The method is applicable to various types of viscose filaments with a fineness of 44.4-555.5dtex, a number of single filaments of 18-100, glossy, matte and semi-dull, and the process is simple and easy to implement. This high-performance homogeneous viscose filament can be widely used in weaving high-grade clothing fabrics, linings, knitwear and other fields, and has great promotion value. After implementation, it will definitely produce significant social and economic benefits.

Description

technical field [0001] The invention relates to a method for manufacturing high-performance homogeneous viscose filaments and products thereof, belonging to the field of textiles. Background technique [0002] At present, the quality of the inner and outer layers of semi-continuous neutral spun viscose filament cakes in China, such as fineness, linear density deviation rate, linear density CV value, dyeing uniformity, etc., has always been quite different, which affects the quality of viscose filament products. Continuous improvement cannot meet the market's demand for reducing the quality difference between the inner and outer layers of the silk cake to weave high-end products. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of semi-continuous spun viscose long filament product, provide a kind of method and its product of manufacturing high-performance homogeneous viscose long filament. [0004] The hi...
