Abstract
The present invention relates to a special-shaped viscose staple fiber, a making method thereof and a spinneret thereof. The feeding material of the special-shaped viscose staple fiber is dissolving pulp, denaturing agents are added at the beginning of post-dissolution in the making process of the viscose fiber, the weight of the denaturing agents is 0.01% to 2% of the weight of alphacellulose, and the special-shaped viscose staple fiber is made via spinning of an approximate conventional technology. The cross sections of a plurality of spinneret orifices in the spinneret are rectangular, and the length diameter ratio is 20:1. The cross section of the made special-shaped viscose staple fiber is rectangular. Textiles made of the special-shaped viscose staple fiber have the advantages of slipperiness, fineness, brightness, gracefulness, strong velvet feeling and three-dimensional stereo perception.
Description
The present invention relates to field of textiles, is a kind of shaped viscose staple and manufacture method thereof and spinning head.
Existing common viscose staple fibre is single circular cross-sectional configuration, can only be used to produce low-grade common artificial cotton or polyester staple fiber and mix and knit, and fabric exists that shrink is poor, intensity is low, yielding, deficiencies such as size is unstable, light resistance difference.The flat 1-260048 of Japan discloses the good viscose rayon nonwoven fabric of a kind of water absorbing properties, the cross section of this viscose rayon nonwoven fabric is 3 above angled construction, have good water imbibition, can be used as industrial production, household supplies, kitchen articles, daily necessities use.But being not suitable as facing fabric uses.
The object of the present invention is to provide a kind of cross section is the shaped viscose staple of rectangle structure, and provide method and the spinning head of making this shaped viscose staple, strong with the fabric shrink that this shaped viscose staple is made into, intensity is high, indeformable, smooth fine and smooth light, elegance is luxurious, the velvet sense is strong, and has the three-dimensional stereopsis style.
The objective of the invention is to be realized by following technical scheme: a kind of shaped viscose staple is characterized in that: the viscose staple fibre cross section is a rectangle.
A kind of manufacture method of shaped viscose staple, by drop into pulp raw material, alkali lye dipping, squeezing, pulverizing, experienced, cooling, metering distribution, yellow, back dissolving, mix, filtrations together, two road filtrations, deaeration, filtrations of three roads, spinning acid bath spinning, boundling, cut-out, soda acid olein are practiced, oven dry is formed, it is characterized in that: dissolve in the back that the 0.01-2.00% by first fibre weight adds denaturant in the viscose glue when beginning.
Denaturant is the polyoxyethylene phenol ether, and its degree of polymerization is greater than 450, and is best by 1% of the fine weight of first.
A kind of spinning head of shaped viscose staple has spinning head body 1, is provided with several spinneret orifices 2 on spinning head body 1, it is characterized in that: the cross section of spinneret orifice 2 is a rectangle.
The length-width ratio of spinneret orifice 2 is 20: 1.
Below in conjunction with following embodiment the present invention is further described.
Fig. 1 is the manufacturing approach craft flow chart of shaped viscose staple of the present invention.
Fig. 2 looks schematic diagram for the spinning head structure master of shaped viscose staple of the present invention.
Fig. 3 is an A-A cross-sectional schematic among Fig. 2.
Fig. 4 is a local I enlarged diagram among Fig. 3.
Fig. 5 is a B-B cross-sectional schematic among Fig. 4.
The raw material of shaped viscose staple: cotton pulp, sulfuric acid, zinc sulfate, sodium sulphate, carbon disulfide, caustic soda, hydrochloric acid and denaturant.The rare phenol ether of polyoxy second that denaturant adopts the auxiliary reagent factory, Tianjin to produce, its degree of polymerization is greater than more than 450.
With reference to Fig. 1, make by the manufacturing approach craft flow chart of shaped viscose staple.Its technological process is: drop into pulp raw material (cotton pulp or wood pulp), alkali lye dipping, squeezing, pulverizing, experienced, cooling, metering distribution, yellow, back dissolving, mix, filtrations together, two road filtrations, deaeration, filtrations of three roads, spinning acid bath spinning, boundling, cut-out, soda acid olein white silk, dry.This technology is that common process is the technology that those of ordinary skill is known.What be different from common process is: denaturant joined in the viscose glue by 1% of the fine weight of first in when beginning back dissolving, thereby produced modified rayon.
