Description
Technical field
The present invention relates to a kind of viscose filament yarn and production method thereof, especially relate to a kind of production method of single fiber fine denier viscose long filament.
Background technology
Viscose filament yarn attribute is regenerated celulose fibre, and the fabric being raw material with it is soft, smooth, and moisture absorption is breathed freely, and fabric draping, is easy to dyeing, antistatic, has excellent wearability, is one of yarn raw material important in field of textiles.At present, viscose filament yarn has defined multifilament fiber number 33.3dtex ~ 666.7dtex, the tandem product scale of filament number 2.22dtex ~ 66.7dtex.In recent years, along with the change of market to high-end textiles demand and the Application and Development of textile industry high-tech, high-performance, the exploitation of functional, differential textile raw material, application are promoted, the fine denier viscose continuous yarn product that fine denier viscose long filament and production technology become viscose filament yarn innovation and development emphasis, particularly below single fiber 1.33dtex becomes the emphasis regenerated celulose fibre raw material needed for grade textiles.Fine denier viscose long filament due to monofilament very thin, its radius of curvature is little, counter-bending stiffness reduces, under identical multifilament fiber number condition, monofilament radical is more, monofilament is thinner, and the specific area of multifilament is larger, its fabric construction is tight, quality is fine and smooth, soft glutinous plentiful, elasticity is high, conformality good, cleaning capacity is strong; Its sucting wet air permeability is more outstanding, " respiratory " is strong, more common silk has dual regulation cool in summer and warm in winter more, the comfortableness of wearability is more excellent, the Fabric Style of viscose filament yarn and functionally to get a promotion, expand, has stronger advantage and effect that is satisfactory and admiration when making the fabric such as silk-like fabric, high density proofed breathable fabric, imitative peach-skin fabrics, clean-cloth, dustless dress material, high absorbency material, Glove suede and dermatine.
At present be mainly real silk, acetate silk and ammonia copper wire for the production of the natural fabric of high-grade silk weaving or knitted fabric fabric and regenerated celulose fibre raw material.Acetate silk and ammonia copper wire monofilament very thin, its fiber number, at below 1.33dtex, even can reach 0.44dtex, and thus its fabric texture softness, good toughness, gloss are soft, and natural in color, environmental protection, moisture absorption, perspire, pendency sense, wearability are similar to silk.But because real silk, acetate silk and ammonia copper wire are expensive, yield poorly, and the reasons such as market supply quantity not sufficient, constrain the exploitation of high-grade fabric and dress ornament, production, the fibrous raw material of the excellent performance that can substitute real silk, acetate silk and ammonia copper wire is actively being sought by manufacturer.The fine denier viscose long filament of below monofilament 1.33dtex is close to real silk, acetate silk and ammonia copper wire in performance, and cost performance is high, and alternative real silk, acetate silk and ammonia copper wire are used for the production of high-grade fabric, dress ornament, expands the application of viscose filament yarn.
Cotton pulp viscose filament yarn is wood pulp, bamboo-pulp viscose filament softness comparatively, and smooth, the stiffness of wood pulp, bamboo-pulp viscose filament are better than cotton pulp viscose filament yarn, and nice and cool, the pro-skin sense of bamboo-pulp viscose filament are better than cotton, wood pulp viscose filament yarn; The health cares such as that particularly bamboo-pulp viscose filament has is antibacterial, antibacterial, deodorization, be cotton, wooden viscose filament yarn is incomparable.That is, the viscose filament yarn that cotton pulp, wood pulp and bamboo pulp are produced respectively has pluses and minuses, just think, if all advantages that the fine denier viscose long filament of below the monofilament 1.33dtex made by cotton pulp, wood pulp and bamboo pulp three kinds mixing pulp has three kinds of silks are problems that we will study at present.Because cotton pulp reactivity worth (glue) is lower than wood pulp, be better than bamboo pulp, spinning spinnability is better than wood pulp and bamboo pulp, and the spinnability of wood pulp is better than bamboo pulp, cotton pulp viscose filament yarn is strong, stretch performance is better than wood pulp and bamboo-pulp viscose filament, so, with cotton pulp, wood pulp is different with the manufacturing technique requirent that bamboo pulp produces viscose filament yarn, at present, the fine denier viscose long filament of below monofilament 1.33dtex is all with cotton pulp, wood pulp, the single raw material such as bamboo pulp carries out producing, as the patent " a kind of superfine-denier cellulose filament fiber and manufacture method thereof " that application number is 201110131575.3, production fiber number is the super fine denier viscose filament yarn of 0.6 dtex-1 dtex, the patent " a kind of fine count fiber element filament fiber and manufacture method thereof " of application number 201110131574.9, produce 20-50D(22.2dtex-55.6dtex) viscose filament yarn, all adopt the single pulp material such as cotton pulp or wood pulp.How its mixture manufacturing being gone out the more superior viscose filament yarn of integrated service performance is people's urgent problems.
