Specific embodiment
Hereinafter, the present invention will be described in further detail.
The present invention relates to a kind of Lyocell fibers, which includes by comprising cellulose pulp and solvent
The spinning of lyocell spinning solution and the lyocell multifilament prepared, wherein constitute the monofilament of the multifilament with having central longitudinal axis
(L1) and the cross section of central minor axis (S1), the length ratio of the central longitudinal axis (L1) and the central minor axis (S1) are 1.5:1
To 10.5:1, and the ratio of the length of the straight line (L2) between the length of the central longitudinal axis (L1) and the central longitudinal axis both ends
It is 1.0 to 1.5:1.
Lyocell fibers of the invention include the monofilament with flat yarn cross section, and cross section is as shown in fig. 1.
In other words, since the length of central longitudinal axis (L1) is at least 1.5 times of the length of central minor axis (S1) and at most
10.5 times, therefore, it becomes the flat yarn with flattened cross-sectional, and in the length and central longitudinal axis of central longitudinal axis (L1)
In the case that the ratio of the length of straight line (L2) between both ends is 1:1, linear flat yarn is formed, and is greater than in the ratio
In the case where 1:1, the flat yarn with curvature is formed.
In this way, the cross section of the flat yarn due to monofilament with flat yarn or with curvature, it can show
The physical property that can not be shown by the existing Lyocell fibers with circular cross section specifically can show to use
In the excellent bendability of industrial materials application, the good sense of touch applied for clothes or interior trim and soft gloss can be shown
Degree, and can show for facial mask non-woven fibre aggregate apply the transparency, skin adherence, such as moisture it is molten
The absorbability and retentivity and smooth surface touch of agent.
Meanwhile the cross section has central longitudinal axis (L1) and central minor axis (S1), and central longitudinal axis (L1) and center
The length ratio of short axle (S1) should be 1.5:1 to 10.5:1, if the ratio is less than 1.5:1, will not show significantly
Flat yarn performance can be difficult to show as a result, and have the visibly different performance of yarn of circular cross section, if it is more than
10.5:1 can then be difficult to fineness required for adjusting final fiber.
In addition, the ratio of the length of the straight line (L2) between the length and central longitudinal axis both ends of central longitudinal axis (L1) is 1.0
To 1.5:1, preferably 1.1:1 to 1.5:1.If the ratio is greater than 1.5:1, curvature can become excessive, as a result, fiber it
Between adhesiveness can reduce and the effect of flat yarn can reduce.
In addition, monofilament of the invention is characterized in that, the length of central longitudinal axis (L1) is 12 μm to 42 μm, central minor axis
(S1) length is 4 μm to 7 μm, can be prepared as 1.0 daniers defined in the present invention are thin to the monofilament of 4.0 daniers
It spends in range.
In other words, due to the limitation of spinning head manufacture and processing technology, it is difficult to realize the length of central minor axis (S1) less than 4
μm, and fineness should be increased so that the length (L1) of central longitudinal axis is greater than 42 μm, this is not significant in terms of fibre fineness.If
The length of central minor axis (S1) is greater than the length of 7 μm and central longitudinal axis (L1) less than 12 μm, then specific surface area can reduce and
Adhesiveness between fiber can reduce.
In addition, since the fineness of monofilament of the invention is 1.0 daniers to 4.0 daniers, and by by the cross of monofilament
Perimeter of section is 22 μm/danier or more divided by the numerical value that fineness obtains, it is therefore preferable to 24.5 μm/danier to 32 μm/denier Buddhist nun
You, therefore, the section girth of per unit fineness increases and the specific surface area of monofilament itself increases, thus, it is possible to be applied to
Effective field, for example, can have the absorbability and retentivity of excellent Essence in facial mask non-woven fibre aggregate.
Above-mentioned Lyocell fibers are biodegradable and environmental-friendly, and the monofilament of Lyocell fibers is with linear flat
The cross section of flat yarn or the flat yarn with curvature, therefore, compared with conventional circular cross section, for resisting the curved of external force
Thus Qu Xingqiang, and fibre bundle mirror-reflection light as mirror have glittering glossiness on the surface.In addition, by
In special cross section effect, sense of touch is coarse and soft, therefore, can be applied to various fields, including industrial materials, such as vapour
Saddle cover, seat webbing, carpet, curtain, cloth application of various clothes etc..
Particularly, if Lyocell fibers according to the present invention are prepared into staple fiber form and are used as facial mask with non-woven
Fiber assembly, then compared with other materials, it can show the transparency of excellent properties, skin adherence, Essence suction
The property received and retentivity, flexible touch etc., these are the very important performances of the non-woven fibre aggregate for facial mask.
As the cross section of fruit fiber be it is flat, then the thickness of fiber reduces, and when being prepared into non-woven fibre set
When body, compared with conventional circular cross section, it is based on identical Unit Weight, the thickness of non-woven fibre aggregate becomes more
Thin, therefore, if be immersed in the cosmetic solvents of such as Essence, it can become transparent and have flexible touch,
And show excellent skin adherence.
In addition, due to compared with the circular cross section fiber of identical fineness, large specific surface area, therefore, for such as essence
The absorbability of the solvent of liquid is high, and Essence retentivity is also excellent as a result, thus with the non-woven fibre aggregate for facial mask
Other materials are compared and show big advantage.
In the case where Lyocell fibers according to the present invention are used as facial mask non-woven fibre aggregate, fineness can be with
For 1.0 daniers to 4.0 daniers.Herein, fineness can be difficult to prepare less than the Lyocell fibers of 1.0 daniers, and if
The fineness of Lyocell fibers is greater than 4.0 daniers, is greater than the conventional fineness for facial mask, therefore, in skin adherence or essence
Magnificent liquid absorbability etc. is not different, and can show the performance of mean level.
The fibre length of Lyocell fibers can be 36mm to 40mm.In Lyocell fibers in above-mentioned fiber length ranges
As facial mask with non-woven fibre aggregate in the case where, in the preparation process of non-woven fibre aggregate, in carding process

The crispation number of Lyocell fibers can be 8cpi to 12cpi.Crispation number can be 5cpi to 20cpi, it is preferred that
For 8cpi to 12cpi.Herein, if crispation number is less than 5cpi, during the preparation process of non-woven fibre aggregate,
In carding process, fibre matting can be low, thus generates technological problems, if it is greater than 20cpi, since crispation number is too high,
It can cannot be appropriately carried out and unlock in carding process.
Based on the Lyocell fibers of 100 weight %, the emulsion content of Lyocell fibers can be 0.1 weight % to 0.4 weight
Measure %.If emulsion content is within the scope of above-mentioned weight %, in the technique as described below that long filament is formed as crimped tow
During, it is possible to reduce the friction of generation, and the curling that can be properly formed between fiber.Furthermore, it is possible to improve non-
In the preparation process of weaving fiber aggregate can cardability.
The base weight of non-woven fibre aggregate can be 30g/m2To 60g/m2, and thickness can be 0.3mm to 0.5mm.
Above-mentioned base weight and thickness range refer to fine containing the lyocell for meeting above-mentioned fineness, fibre length, crispation number and emulsion content
For improving the absorbability of liquid composition, the optimum range of transparency and adhesiveness in the non-woven fibre aggregate of dimension.
Weight based on Lyocell fibers, the water absorption of non-woven fibre aggregate can for 1000% to
1600%.As described above, although Lyocell fibers are hydrophilic and compared with other fibers there is relatively high moisture to inhale
The property received, but if meeting the above-mentioned performance of Lyocell fibers, and at the same time meeting the above-mentioned base weight of non-woven fibre aggregate
And thickness range, then the water absorption of the non-woven fibre aggregate containing Lyocell fibers is adjustable to above range.
Compared with before the moisture solution, transparency of the non-woven fibre aggregate after moisture solution can for 80% to
84%, and compared with before Essence processing, the transparency after Essence processing can be 88% to 94%.Since Lay is matched
The fineness of your fiber is 1.0 daniers to 4.0 daniers, therefore, the thickness of the non-woven fibre aggregate containing Lyocell fibers
Degree becomes than usually thin, if non-woven fibre aggregate immersed in the liquid composition of moisture and Essence etc.,
It can have transparency and flexible touch in above range.
Skin adhesion of the non-woven fibre aggregate after moisture solution can be 3.6gf to 4.2gf, and non-knit
Making skin adhesion of the fiber assembly after Essence processing can be 4.5gf to 5.3gf.If meeting Lyocell fibers
Performance, while meet containing its non-woven fibre aggregate base weight and thickness, then non-woven fibre aggregate can expire
The skin adhesion of sufficient above range.
Based on the non-woven fibre aggregate of 100 weight %, the emulsion content of non-woven fibre aggregate can be 0.001
Weight % or less.Since when preparing non-woven fibre, during the spun lacing of water jet process, what is contained in Lyocell fibers is big
Partial emulsion is washed off, and therefore, non-woven fibre aggregate shows above-mentioned emulsion content.
Hereinafter, the preparation process detailed description by non-woven fibre aggregate is contained into the non-woven of Lyocell fibers
