Abstract
Flat filaments have a flatness (A/B) of 7 to 25, where A is a length of at least one of the two longer sides of a substantially rectangular, transverse cross-section of each filament and B is a length of at least one of the two shorter sides of the substantially rectangular, transverse cross-section of each filament. The flat filaments also have a fineness of 0.5 to 40 denier, and are provided on each of the two longer sides with one or more ribs continuously extending in a direction of an axis of the filament and having a width W and a height H. The number of the ribs on each longer side ranges from 1 to A/2W, the rib width W ranges from B/2 to 3B, and the rib height H ranges from B/2 to 2B. The filaments have excellent nontackiness and bulkiness and permit easy elimination of crimps by polishing, and can be suitably used as raw fibers which, when formed into a pile product, provide the pile product not only with a soft feeling but also with resilient and substantial feeling.
Description
The present invention relates to be used as the long filament of chenille articles raw material, also relate to the raw fiber of fleece.The present invention more specifically relates to the flat filaments of being with rib, it is being excellent aspect the brushing effect, be so flat silk character, they keep not bonding or entanglement mutually, bulkiness with excellence, soft surperficial feel and resilience and texture can be provided, and to such as woollen goods toy animals, a chenille articles of interior trim fabric and fabric is best, also be specifically related to the raw fiber of fleece, described raw fiber contains flat filaments and can allow the chenille articles that rises that obtains have soft-surface feel and excellent resilience and texture.
Natural hair generally is made of such hair, compares with their radicle branch, and their free end portion diameter reduces, resilience that let it be and material outward appearance, and its surface contact feel provides characteristic softness and resilience feel.
Recent years,, the trend of avoiding using natural hair is arranged from conservation of nature environment viewpoint.This strong request that has caused giving prominence to develops the chenille articles that synthetic fiber prepare, and these goods have and the comparable soft feel surface of natural hair, represent good resilience during pressurized and have texture.
Among the synthetic fiber, the Dralon class can quite easily provide special soft feel.Therefore the chenille articles that rises of many Dralons and the preparation of similar hairs puts on market in a large number.Yet, use fiber inevitably with constant thickness, when fiber is used as the thickness formation of its root portion, can cause coarse and the hard feel, can cause not having the resilience feel when perhaps forming fiber with the thickness that is same as its free end portion.
Be the example of prior art below, known these technology provide a chenille articles that uses near the synthetic fiber of natural woolen handle:
(1) a kind of technology, make the trend of using be, fiber with flat cross section or oval cross section, with same fiber number but the fiber of circular cross-section compare, be easy to bending at least in one direction and provide more soft contact feel (for example open JP-A-59524/1975 of Japanese Patent Laid);
(2) a kind of technology, the polyester fiber manufacturing rise a chenille articles pile free end portion be easy to by free end portion flood in alkaline aqueous solution and hydrolysis method by nodeization (JP-A-16906/1980), perhaps the free end portion of boundling polyester fiber is to flood the mode nodeization (JP-A-134272/1981) of free end portion in alkaline aqueous solution;
(3) a kind of technology obtains to have no matter the characteristic of its root thickness softness contacts the fiber of feel, and method is to have the fiber spinning in Y type cross section and to make the fiber free end portion be torn (JP-B-51564/1989) to this fiber application of force;
(4) a kind of technology, use such fiber, also there is the flattened rectangular cross section at its Denier range 1.5-4 dawn, direction in its short side is flexible, surface roughness in each fiber periphery is 1-6, and the chenille articles that rises that this fiber is used for preparing has the soft-surface feel and the brushing effect (JP-A-200808/1990) of improvement.
(1)-(4) way has all obtained soft-surface feel and resilience and texture and has not used fine hair.According to the detailed description of technology (1), observe the formation impression at oval cross section, make the feel that is clamminess of polyester fiber inherence obtain improvement.But the gained feel has been utilized oval cross section more or less, during hand, can not obtain and natural mao of soft-surface feel and resilience and the texture of comparing fully, expects as the present invention.According to technology (2), the definition of fiber is restive, and in addition, the hydrolysis in alkaline aqueous solution has to intermittently make productive rate low.And according to technology (3), because cross sectional shape requires the water retention rate height, dry burden is big significantly.Commercial Application is needed special consideration.Therefore, obtaining cheaply to this technology, large-tonnage product is difficult.At last, according to technology (4), the direction of fiber short side in its cross section is tending towards crooked and owing to the surface roughness that it had, fiber has inappropriate high stiffness.According to the narration of its specification embodiment, shown that the fleece that fiber provides has bigger bulkiness, because compare, between adjacent fiber, lack tight contact with fiber with " simple flattened ".But this fleece lacks the soft-surface feel.
Can recognize the numerous difficulty that require the aspect that satisfy the chenille articles needs from above narration.
Except that technology (1)-(4), it is known still having additive method.According to this method, the raw fiber that has formed chenille articles comprises can not high shrinkage and the combination of collapsible fiber.Under xeothermic or wet heat condition, only have collapsible fiber to be caused shrink to make can not high shrinkage and collapsible fiber be allowed to respectively to keep as guard hairs and fine hair.
To playing chenille articles, it is preferred providing the such surface of resilience and texture when having soft feel and pressurized.Has the surface that soft feel plays chenille articles in order to provide, the important point is how to eliminate to curl from guard hairs, curl and be hidden in the fine hair, perhaps how easily to convert it to can stretch fiber by so-called polishing step, the surface of playing chenille articles in the polishing step softly rubs with hot-rolling and follows contraction by fine hair.
At last, the ratio that reduces acrylonitrile in acrylonitrile copolymer is used for preparing fiber makes acrylonitrile copolymer can have the heat distortion temperature of reduction, and this is known effective.If the copolymerization amount of acrylonitrile is reduced in the acrylonitrile copolymer, the transparency of dyestuff and the colorability of fiber are compromised, and in addition, the feel that plays chenille articles is tending towards changing by slight thermal histories such as for example dryings.Therefore gained plays chenille articles is difficult to handle.
According to this technology, resilience and texture are produced by fine hair during pressurized.At this moment, the contraction factor of fiber and bulkiness thereof and texture, they are relevant with the cross sectional shape of collapsible fiber, will become key factor.
Overcome the method for this problem, for example JP-A-21978/1985 and 209048/1985 disclosed technology, its contraction factor at least 15% of collapsible fiber, interfibrous static friction coefficient are 0.23 or lower and be easy to shrink, and have been used as the fine hair in the chenille articles.For controlling static friction coefficient below 0.23, using the amino silicone softener is basic demand.
Yet the siloxanes softener is tending towards being deposited on the hot-rolling with the rubber-like form during the drying steps of fiber spinning technology, and therefore the trend that causes technological problems is arranged.So need a kind of technology of not using this softener.
An object of the present invention is to provide the flat filaments of band rib, it is being excellent aspect brushing effect and the bulkiness, allow and be easy to eliminate curling by polishing, has soft feel and remarkable resilience and texture after having formed chenille articles, they are fit to do the raw fiber of fleece and to woollen goods toy animals, interior trim fabric and fabric etc. are best.Other purpose of the present invention provides the raw fiber of fleece, and it contains the flat filaments (hereinafter note is made " band rib flat filaments ") of above-mentioned band rib, and presents soft feel when forming fleece.Further object of the present invention provides the raw fiber that comprises above-mentioned band rib flat filaments and specific collapsible fiber, this raw fiber does not need to carry out making its bending such as the special disposal that applies the siloxanes softener, and the chenille articles that rises that obtains not only has the soft-surface feel but also has excellent resilience and be similar to the texture of natural hair.
In first purpose of the present invention, the flat filaments glacing flatness (A/B) that therefore provides is 7-25, and A is that described filament cross is the length on two long limits of rectangle substantially, and B is that described filament cross is the length of two minor faces of rectangle substantially; Fiber number is the 0.5-40 dawn; Each limit on described two long limits all has one or more crest lines, this crest line is axially expanded continuously and is had width W and a height H described long filament, number range at each the above crest line of long limit is 1-A/2W, and described width W scope is that B/2-3B and described height H scope are B/2-2B.
In second purpose of the present invention, the raw fiber that is used for fleece also is provided, it comprises the band rib flat filaments of the 10wt% at least of above-mentioned qualification; At least 90wt% and glacing flatness (A '/B ') are the flat filaments of 5-25, and A ' is that each described filament cross is the length on two long limits of rectangle substantially, and B ' is that described filament cross is the length of two minor faces of rectangle substantially, and fiber number is the 1-40 dawn.
In the 3rd purpose of the present invention, the raw fiber that is used for fleece also is provided, it comprises the band rib flat filaments of the 20-60wt% of above-mentioned qualification; 20-50wt% have contraction factor at least 15% and fiber number is the collapsible fiber at 1-5 dawn; With 60wt% or lower can not high shrinkage.
The present invention is described in detail in detail now.The explanation of enclosing, term used herein " fiber number " itself means " fiber number of single long filament ".
Band rib flat filaments of the present invention requires to have the 7-25 glacing flatness of A/B limited proportion, wherein A is that filament cross is the length on two long limits of rectangle substantially, described cross section is axial perpendicular to long filament, and B is that filament cross is the length of two minor faces of rectangle substantially.Be more preferably the straight of 7-15.
Not preferably less than 7 glacing flatness, because this long filament is tending towards tangling the surface of causing harsh hand when having made chenille articles each other.On the other hand, glacing flatness was difficult to prepare chenille articles greater than 25 o'clock, because the stretch capability of this long filament owing to having reduced spinning has lower mechanical strength.
Term used herein " basic rectangle " limits band rib flat filaments cross section essential part of the present invention (promptly, remove the part that still keeps behind the crest line), its shape should be interpreted as not only comprising rectangle but also comprise elliptical shape, as long as they can reach above-mentioned purpose of the present invention.
For long filament, it is necessary that each of two long limits of filament cross has a crest line at least.Require crest line in axially expansion continuously of long filament, and it has width W and height H, described width W scope is that B/2-3B and described height H scope are B/2-2B.
Owing to be equipped with these crest lines that long filament is axially expanded continuously, it is loose and poly-not that adjacent long filament keeps, thereby have excellent brushing effect and bulkiness, represents soft feel and level and smooth resilience and texture when it has been formed chenille articles.
If the width W of rib less than B/2 or less than 3B, can not be observed the effect of crest line, this long filament presents feel and brushing effect hardly, has no difference with the result who uses simple flat silk.If ridge height, be can't see the effect of crest line less than B/2, this long filament presents feel and brushing effect hardly, has no difference with the result who uses simple flat silk.If ridge height surpasses 2B, this long filament can not prepare with high yield.
In addition, the number of the crest line on every long limit of long filament should be an integer, and scope is 1-A/2W.If the number n of these crest lines surpasses A/2W, in the middle of adjacent long filament, do not stay too many space, make the brushing effect reduce, and the result of the long filament of feel and the simple flat cross section of use have no difference.
The fiber number of band rib flat filaments of the present invention should be the 0.5-40 dawn, preferred 2-25 dawn, and 3-20 dawn the best.Not preferred fiber number because this long filament is tending towards tangling each other, causes the harsh hand surface less than 0.5 dawn when having formed chenille articles.On the other hand, fiber number can not present soft feel greater than 40 dawn when having formed chenille articles.
Every crest line is placed on is with the position of rib flat filaments to be not particularly limited, as long as be positioned at the long limit of long filament essential part.From the viewpoint of feel, the mid point of crest line width is arranged in long limit, and to light to A/4 be particularly preferred.
Although the cross sectional shape to every crest line is not particularly limited, the preferred such shape in the cross section of crest line does not promptly form any groove between crest line and long filament essential part, want controlled very low because its water is deposited in the spinning step.The illustrative embodiment of cross sectional shape comprises triangle, and is square, rectangle, other polygons and semicircle.Only the cross sectional shape that limits with curve rather than seamed edge is particularly preferred, because this raw material long filament is also in the good cohesion of spinning step performance, and when having formed chenille articles, reduced the mutual hook block of long filament, made chenille articles have the soft-surface feel of enhancing.
Term used herein " interior poly-" expression is in any case or without any the performance of inconvenience, such as in the yarn that will this long filament forms as a chenille articles intermediate materials broken yarn not taking place.If interior poly-poor, must extend and treat the Cutting Length of spinning material fiber.When the cross sectional shape of every crest line was formed by single curve, the Cutting Length of raw fiber can be selected from the scope of broad, made that this cross sectional shape is useful to regulating feel.
The preferable range of width W and height H (can strengthen long filament feature of the present invention) is B/2-2B, is B-2B to width W, is B/2-B to height H.It is possible that W and H are set within these scopes, and decapacitation accesses outside the advantageous feature of raw fiber, can also prepare long filament and then obtain best interior poly-in the spinning step with good yield in the spinning step.
Promote the more important of soft feel and set ratio in addition, promptly the flat part total length will be at higher value to the ratio (A-nW/A) of long edge lengths in band rib flat filaments essential part.This is worth preferred 0.6 or bigger, is more preferably 0.7 or bigger.
The acrylic filament that band rib flat filaments is preferably made by acrylonitrile polymer, because among the synthetic fiber, acrylic filament obtains soft feel especially easily, and is being excellent aspect dyestuff definition and the colorability.
The manufacturing of the flat acrylic filament of band rib hereinafter is described in detail in detail.
Acrylonitrile polymer that be fit to make the flat acrylic filament of band rib is a kind of acrylonitrile copolymer, by 50wt% or more acrylonitrile with can constitute with the unsaturated monomer of acrylonitrile compolymer.
When particularly being with the rib flat filaments to be used in combination with collapsible Dralon and/or other Dralons, acrylonitrile polymer contains 90wt% or more acrylonitrile is preferred.
Acrylonitrile content is lower than 50wt% and can causes long filament in thermal property, and dyestuff definition and colorability aspect are inferior.
But the unsaturated monomer that uses as copolymer composition is not particularly limited.Its typical examples comprises acrylic acid, methacrylic acid and derivative thereof; Vinyl acetate, acrylamide, Methacrylamide, dichloroethylene and vinylidene chloride; According to application, also has ionic unsaturated monomer such as vinylbenzenesulfonic acid sodium, methylallyl benzene sulfonic acid sodium salt and acrylamido methyl propane sulfonic acid sodium.
Polymerization technique to acrylonitrile polymer is not particularly limited.For example, the suspension polymerization of available routine or polymerisation in solution.
Molecular weight to the acrylonitrile polymer made is not particularly limited in addition, and molecular weight ranges falls into the used normal ranges of preparation acrylic filament and gets final product.Yet preferably when 25 ℃ are measured with the dimethyl formamide solution forms of 0.5wt% reduced viscosity in the 1.5-3.0 scope.
By acrylonitrile polymer is dissolved the preparation spinning solution in solvent, make the concentration of acrylonitrile polymer fall into the 15-28wt% scope.Then this spinning solution is similar to the spinning plate of filament cross section shape eye profile that requires and spins by having.If the concentration of acrylonitrile polymer is lower than 15wt% in spinning solution, then the cross sectional shape of the profile of fine spinning eye and long filament differs from one another basically when condensing.This just makes and is difficult to obtain desired cross sectional shape.This low concentration is not preferred.If concentration surpasses 28wt%, it is the stability of benchmark with time that spinning solution has lower, makes its spinning property reduction.This high concentration is not preferred equally.
The useable solvents example comprises organic solvent such as dimethyl formamide, dimethylacetylamide and methyl-sulfoxide; With other solvents such as nitric acid; The thiocyanic acid aqueous solution; And solder(ing)acid.When plan was controlled cross sectional shape by the profile of fine spinning eye, organic solvent was useful.By spinning by this way and batching, promptly with the coiling speed of the long filament that condenses the ratio of the linear transporting velocity of spinning solution being defined the spinning head stretches, and make its scope that falls into 0.7-2.0, can obtain to be similar to substantially the flat acrylic filament of the cross sectional shape of fine spinning eye profile.If the spinning head stretches greater than 2.0, can cause broken yarn at the body lotion intermediate frequency that condenses numerously, thereby be difficult to obtain long filament itself.
The long filament that condenses that will so obtain afterwards stretches under known condition by conventional method, washing and dry, thus obtain the flat acrylic filament of the present invention.According to application, the gained long filament is carried out hot loose processing or other similar processing to give well balanced engineering properties, after this be cut into raw fiber.
Then narration is used for the relevant raw fiber of fleece, this raw fiber comprises flat filaments: it has the glacing flatness (A '/B ') of 5-25, A ' is that described filament cross is the length on two long limits of rectangle substantially, B ' is that described filament cross is the length of two minor faces of rectangle substantially, and fiber number is the 1-40 dawn; And band rib flat filaments of the present invention.
If the raw fiber of fleece only constitutes with single flat filaments, then long filament such as above-mentioned tightly interior poly-makes its brushing effect reduce, and these goods have harsh hand when having formed chenille articles.If form raw fiber to give soft feel with the super-flat long filament with big glacing flatness, then gained plays chenille articles has above-mentioned shortcoming and also reduces resilience.Yet, band rib flat filaments of the present invention is mixed with flat filaments, this band rib prolate silk is inserted in self is tending towards each other between the tightly interior poly-flat filaments.Therefore poly-in this long filament prevents, make the brushing effect obtain improvement.In addition, because of each long filament exists independent of one another, when they are heated at polishing step, can be with its direct contact heat roller.This helps heat conversion between hot-rolling and each long filament, makes that eliminating curls to curl easily than eliminating in the raw fiber that only is made of band rib flat filaments of the present invention from this long filament.Therefore the chenille articles that rises that obtains has flat filaments by the structure that strengthens with the rib flat filaments, has made chenille articles have resilience and texture, and there is soft feel on its surface simultaneously.
At this moment, it is 5-25 that the flat filaments that mixes with band rib flat filaments requires its glacing flatness (A '/B '), A ' is that the flat filaments cross section is the length on two long limits of rectangle substantially, B ' is that the flat filaments cross section is the length of two minor faces of rectangle substantially, and fiber number is the 1-40 dawn, the preferred 2-30 dawn, the best 5-15 dawn.
If the glacing flatness of the flat filaments that should mix is less than 5, this flat filaments is difficult to have flexibility, thereby is difficult to obtain the chenille articles that rises of similar natural hair.On the other hand, if glacing flatness greater than 25, the flat filaments of this mixing have strong each other in poly-trend, like this, even during mixed zone rib flat filaments, band rib flat filaments can not fully be showed the improvement degree of brushing effect.
If the fiber number of the flat filaments that should mix is less than 1 dawn, long filament is tending towards tangling each other, and it has the surface of harsh hand when then having formed chenille articles.If fiber number is greater than 40 dawn, when they had formed chenille articles, no matter how this long filament can not show soft feel to its flat profile.So be difficult to obtain the chenille articles that rises of similar natural hair.
As for the mixed proportion of the flat filaments of being with rib flat filaments and mixing, the former should be 10wt% or more, preferred 30wt% or more.If this ratio is less than 10wt%, the ratio of the band rib flat filaments between the flat filaments of this mixing is too small, and band rib flat filaments can not effectively prevent the mutual bonding and interior the gathering of the flat filaments of this mixing.Formed the surface that is tending towards having harsh hand behind the chenille articles.Needless to say, the raw fiber that is used for fleece can only be made of band rib flat filaments of the present invention.
Be used for forming the raw fiber preferred flat acrylic filament of the present invention with fleece, this is easy to obtain the particularly soft feel because of acrylic filament among the synthetic fiber and is being excellent aspect dyestuff definition and the colorability.
Flat acrylic filament can prepare by the similar technology of above-mentioned preparation band rib flat filaments, and difference is that the profile of fine spinning eye must change, and makes it to be similar to substantially the profile of flat acrylic filament cross sectional shape.
Mixed zone rib flat filaments and flat filaments or only can obtain being used for the raw fiber of chenille articles according to the above ratio with band rib flat filaments.Afterwards this raw fiber is formed fleece, such as the hair scarf, high pile fabric or carpet.
Next the raw fiber that the present invention is used for fleece is described in detail in detail, and it is by collapsible fiber, and the fiber number of its collapsible factor at least 15% and single fiber is the 1-5 dawn, and band rib acrylic filament constitutes.These raw fibers hereinafter are called " collapsible-fiber-raw materials mixed fiber that is used for fleece ".
Natural hair is not only showed characteristic resilience and texture in weight but also when gently pressing.When light pressure, the above-mentioned raw fiber feel that is used for fleece is very near the feel of natural hair, rather than during weight, and the raw fiber that is used for fleece can not obtain the resilience and the texture that are had as natural hair.Be further improvement feel, thereby be used in combination the collapsible long filament that becomes fine hair when having formed chenille articles.
Can obtain being used for the collapsible-fiber-raw materials mixed fiber of fleece, method is with band rib flat filaments, and the fiber number with the collapsible factor at least 15% and single fiber is the collapsible fiber at 1-5 dawn and can not mixes by high shrinkage.Must set the ratio of each fiber, be 20-60wt% to band rib flat filaments, is 20-50wt% to collapsible fiber, and to can not high shrinkage being 60wt% or lower.
In this case, band rib flat filaments has high stiffness, makes them be tending towards being kept upright in playing chenille articles.In fleece preparation technology's so-called polishing step during with hot-rolling contact zones rib flat filaments, band rib flat filaments can contact hot-rolling and not crooked.This becomes possibility with regard to making the thermal conversion efficiency of improvement from hot-rolling to band rib flat filaments, thus curl can be easy to stretching.
Can not play the surface that chenille articles provides soft feel if be used for the ratio of the collapsible-fiber-raw materials mixed fiber band rib flat filaments of fleece to gained less than 20wt%.On the other hand, ratio is greater than 60wt%, and the very difficult effect that shows the collapsible fiber of this mixing fully promptly is difficult to obtain improvement aspect the resilience of resultant pile fabric and the texture when the weight fleece.
The collapsible factor that becomes the collapsible fiber of fine hair when forming fleece is 15% or bigger, preferred 20% or bigger.The collapsible factor can cause fine hair to sink less than 15% to the root portion of being with the rib flat filaments, and fine hair can not play the effect of giving fleece resilience and texture when making weight.
Additional disclosure, term used herein " at least 15% (20%) the collapsible factor " expression, not only damp and hot collapsible Hui Zi (boiling water treating was measured after 3 minutes) but also in the collapsible factor of heat (130 ℃ handle 10 minutes after measurement) be at least 15% (20%).
If less than 20wt%, the gained fleece can not show strong resilience and texture when weight in the ratio that is used for the collapsible-fiber of fleece-collapsible fiber of raw materials mixed fiber.On the other hand, this ratio can cause the filament density on fleece surface low greater than 50wt%, thereby makes fleece that surface flatness can not be provided.
Collapsible fiber must have the fiber number at 1-5 dawn.Fiber number is less than 1 dawn, can cause the entanglement of collapsible fiber self or collapsible fiber and entanglement as the band rib flat filaments of guard hairs, therefore makes collapsible fiber be difficult to average shrinkage.Otherwise fiber number can make fleece coarse in its long filament root thoughts and feelings greater than 5 dawn, therefore reduces quality.
In addition, if ratio that can not high shrinkage surpasses 60wt%, this can not need to use by high shrinkage except that band rib flat filaments and collapsible fiber, then therefore reduce, thereby make soft feel, resilience and the texture on the surface that fleece had all reduce as the band rib flat filaments of guard hairs with as the ratio of the collapsible fiber of fine hair.
Also have, use have the collapsible of specific sectional shape and/or can not high shrinkage as collapsible and/or can not will further improve the quality of fleece by high shrinkage.
As the cross section part of this specific sectional shape fiber, must satisfy following three requirements simultaneously.
(1) outline line in each cross section must be only by no seamed edge curve limit.
(2) following formula: 2≤a/b≤5 should be satisfied in each cross section
Wherein, the cross section is when being clipped in two parallel lines, and a is two ultimate ranges between the parallel lines
And b is two minimum ranges between the parallel lines.
(3) each cross section at least two indenture of regulation is at diverse location.
Satisfy (1)-(3) when requiring, the chance of the mutual suspension hook of single fiber will reduce and cause collapsible filament contraction to become fine hair.Therefore make collapsible fiber average contraction, make fleece have the resilience and the texture of further improved excellence.Effect that can not high shrinkage is to prevent to be with the rib flat filaments to get together in fleece, makes fleece have further improved quality.If cross section that can not high shrinkage is only by curve limit, poly-effect can further be strengthened in they prevented.
That obtain and the fiber that have above-mentioned feature of any known technology all can be used as collapsible-fiber-raw materials mixed fiber that collapsible fiber is used for fleece.Preparation technology to them is not particularly limited.Collapsible Dralon is preferred especially because of its superfine dyestuff definition and coloring.
Collapsible Dralon can prepare with processes well known, and has the cross sectional shape that satisfies above-mentioned (1)-(3) requirement, and the profile of fine spinning eye and spinning condition can suitably select also combination so that obtain the collapsible Dralon of the cross sectional shape that requires.
As for all kinds of the fiber of the collapsible-fiber-raw materials mixed fiber that is configured for fleece, be not particularly limited and be in its spinning step or in burnishing oil, give, this oil be used to dye or similar technology after post processing.
When requiring painted raw fiber, need only carry out,, perhaps use producer-coloured fibre or coloured fiber such as forming the raw fiber poststaining with staining technique well known in the art.
Band rib flat filaments, collapsible fiber (if desired) and can not mixing according to the above ratio by high shrinkage, and, formed chenille articles as the raw fiber of fleece with known sanding, such as scarf, high fleece or carpet.
The present invention further specifies by following examples, and wherein each measurement data is measured with following method.
