Description
Technical field
The utility model relates to " W " shape long filament.
Background technology
Along with the raising of living standards of the people and the improvement of quality of life, lining, style and the style of dress ornament to the wearing comfortableness energy, all there has been higher requirement.As the most basic structure of garment material---fibrous material, should make great efforts the various fibrous materials of developmental research by the technological progress of self, satisfy people's demand.The traditional fibre cross section is circular, profiled fibre cross-section then mostly is triangle, trilobal, five-pointed star shape, beans shape, diesis cross section, flat cross section and irregular geometric figure (T, Y shape) etc., the profiled filament characteristics comprise: the geometric surface index of refraction of fiber is different, and as prism, make light produce refraction and beam split, and then reflect colorful light; Gap between fiber and yarn is many, has air permeability and good than the common textiles of same specification; Fiber surface area is big, and absorption property is good, can be used as material for air purification; The cohesive force of fiber is strong, and fluffing and pilling effect can significantly reduce, and also can improve drapability and wrinkle resistance etc.
Because the characteristic of the cross sectional shape of fiber and fiber is closely related, can obtain the needed various characteristics of people by means of the change of fibre section shape.Comparatively remarkable to the influence of the wicking properties of yarn such as the precursor cross sectional shape, it is five leaf that experiment shows that the wicking of " H " tee section precursor is better than, and the yarn wicking of "T"-shaped cross section precursor is the poorest.But the function of existing fiber species is all more single, and the lining of market demand multifunctional and composite type.Such as moisture sorption effect reasonable " ten " font fiber, the lining feel of working it out is coarse, mainly is because Asian skin is relatively finer and smoother.The doughnut warmth retention property is good, but can not in time discharge the moisture of body surface.Autumn and winter season, it is cold that weather changes gradually, and motion back is owing to catch a cold especially easily once heat one is cold out of doors, so with regard to needs and existing good moisture absorption possesses the clothes that the multifunctional and composite type fiber of good warmth retention property is made.
Summary of the invention
The purpose of this utility model provides a kind of " W " shape long filament, it is the filament fiber product of " W " shape that a kind of cross section just is provided.
The utility model is a kind of " W " shape long filament, has solved that coarse, the warming fiber of moisture absorbing and sweat releasing feel is airtight leads wet problem, has remedied the deficiencies in the prior art.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is a kind of " W " shape long filament, and the shape of cross section of this filament fiber is " W " shape.
As optimized technical scheme:
Aforesaid a kind of " W " shape long filament, wherein, the filament number of described fiber is the 0.1-20 dawn;
Aforesaid a kind of " W " shape long filament, wherein, the opening angle theta 1 of the W shape cross section of described fiber is 30 °～110 °, and θ 2 is 30 °～110 °, and θ 3 is 30 °～110 °;
Aforesaid a kind of " W " shape long filament, wherein, drift angle (1), both sides (2) and (2 '), bottom drift angle (3) and (3 ') and connecting portion (4) and (4 ') in the middle of " W " shape cross section of described fiber comprises; Drift angle (1) is the combination of single circular arc or straight line and circular arc or the combination of several circular arcs in the middle of described; Described both sides (2), (2 ') length can equate, also can be unequal; Described bottom drift angle (3), (3 ') are the combination of single circular arc or straight line and circular arc or the combination of several circular arcs; Described connecting portion (4), (4 ') are straight line or circular arc.
Not only moisture absorbing and sweat releasing is effective for " W " of the present utility model shape filament fiber, and fibrous inside has certain air content, and good bulking intensity is arranged, and more air content is also arranged between fiber, can improve the warmth retention property of fabric.
The beneficial effects of the utility model are:
Not only moisture absorbing and sweat releasing is effective for " W " of the present utility model shape filament fiber, and warmth retention property is good; " W " of the present utility model shape filament fiber feel is smooth, satisfies woven, knitting requirement; The clothes that the utility model is made can keep inner dry and comfortable, and is comfortable and easy to wear warm." W " of the present utility model shape filament fiber is the multifunctional and composite type fiber that existing good moisture absorption possesses good warmth retention property again.
The fiber appearance profile of " W " tee section that the utility model is special makes fabric that fluffy sense be arranged, and has improved gloss effect and feel, has improved fabric moisture, gas permeability, smooth feeling and pilling resistance.That W shape FDY, the DTY of final products is made into is woven, knitted fabric etc., the good hand feeling of fabric, light, fluffy sense is arranged, the moisture absorbing and sweat releasing of fabric obviously is better than ordinary polyester, can be directly used in the making of three different fabrics after " W " shape FDY, POY, DTY, HOY etc. and other fiber filament interlacing, be simulate wool, the new material of imitative fiber crops.W shape fiber has not only improved the feel and the gloss of fiber, can produce atomic little space between fiber simultaneously, makes fiber have suction and ventilative function, has improved the comfortableness of fabric.Be applicable to the mesh lining, (clothes) embroidery lace of processing training clothes, recreation clothes, sweat shirt, golf, tennis togs, overcoat, coat, shirt, gym shorts, nightwear, Western-style clothes etc. etc.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
As shown in Figure 1, 2, a kind of " W " shape long filament, the filament number of fiber was 1 dawn; The opening angle theta 1 of " W " shape cross section of fiber is 60 °, and θ 2 is 60 °, and θ 3 is 60 °; The middle drift angle (1) of " W " shape cross section of described fiber is single circular arc, both sides 2,2 ' equal in length; Bottom drift angle (3), (3 ') are single circular arc, and connecting portion (4), (4 ') are straight line.
This fiber adopts " W " shape spinneret orifice to make by high-speed spinning process, and its technology circuit is: the FDY fused mass directly spinning.Spinning speed 1600-2200m/min, behind two pairs of hot-rolling drawing and settings, the product macromolecular structure is stable, constant product quality.Be characterized in that technological process is short, production efficiency height, FDY can long-term storage, long-distance transport.
The design of spinning W shape fibre technology, should consider that mainly W shape specific area is bigger than circular cross-section fiber, threadline cooling rate is fast, and its structural homogeneity is more responsive than circle to cooling condition, should select the cooling condition that relatively relaxes, so the process for cooling of lateral blowing is one of key technology that is shaped.The DTY production technology is different, and this process route can keep cross sectional shape preferably for FDY---technological design and POY of DTY spinning W shape---.The residual stretch of W shape FDY is than low, and back processing draw ratio is low than other POY kind, adds other process conditions such as the D/Y of bullet processing, and process velocity etc. are also answered corresponding adjustment, to guarantee the suitability for industrialized production of W shape DTY.
W shape FDY polyester filament fiber with spinning 55d/36f is an example.Utilize homemade " W " shape spinnerets, spinning speed 2000m/min, 290 ℃ of spinning temperatures, 90 ℃ of first hot-rollings, 120 ℃ of second hot-rollings, slicing characteristics viscosity 0.670dL/g, lateral blowing speed 0.40m/s, the condition spinning that environment temperature is 30 ℃ forms.
