Abstract
The utility model relates to a cross-simulated ECDP/PET composite fiber. The fiber is cross-simulated; a spinneret plate is provided with at least one spinneret hole; and the spinneret hole is cross-simulated, and is formed by connecting a rectangle at the edge part and a circle at the middle part. The composite fiber has the advantages that the cross-simulated fiber has low single-fiber fineness, profile degree guarantee and even yarn levelness, and the fabric has soft hand feeling; and compared with other cross special-shaped fiber, the hollowness is increased, grooves on the silk section of the cross-simulated fiber are unchangeable so as to ensure the moisture absorption and perspiration functions of the fiber, and all the heat retention, softness and even yarn levelness are obviously improved. Moreover, the ECDP molecular chain contains a flexible hydrophilic molecular chain to endow the fiber with good antistatic property and comfort; and during spinning, the temperature responses of two components with different flow viscosities endow the fiber with permanent elasticity.
Description
[technical field]
The utility model relates to functional fibre technology and field, specifically, is a kind of imitative cross ECDP/PET composite fibre.
[background technology]
Along with the raising of people's living standard and the development of fashion trend, sportswear becomes widely popular, and people begin the moisture absorbing and sweat releasing demands for higher performance to garment material thus.Natural fabric brings clammy sensation to the people easily after the human body perspire, and chemical fibre has advantage than natural fabric aspect wet transmitting performance.So each company of late nineteen seventies early eighties begin one's study the exploitation moisture absorbing and sweat releasing chemical fibre.At the beginning of nineteen eighty-two, Japanese Supreme Being people company just began the water imbibition Study on Polyester Fiber, and the hollow porous fibre of its development has been applied for patent in 1986; 1986, du pont company was released the hydroscopic sweat-eliminating polyester fiber of " coolmax " by name first.E.I.Du Pont Company in 1999 releases upgrading coolmax alta serial stock distributing in conjunction with the patented technology of the low dosing fast dry characteristic of research and development.Subsequently, many fiber production merchants in Taiwan rely on the technological development advantage of self, the fiber that continuous mutually development, exploitation have the moisture absorbing and sweat releasing performance.Taiwan is far spun and has been developed successfully the topcool hygroscopic fibre, in emerging weaving released the coolplus of cross section, Japanese Japan spins company and has also developed the polyester textile of breathing " ekslive ".
In recent years, people require more and more higher to comfortableness, health, security and the feature of environmental protection etc. of garment material, along with people's increase of activity time out of doors, Casual Wear and sportswear interpenetrate and the trend that combines together also is subjected to consumers in general's favor day by day, the lining of these class clothes had both required good comfort, required again when movable heartily, in case situation soaked with sweat occurs, clothes can not pasted skin and produce cold wet sense.
Profiled filament is meant that the fibre section is not the fiber of solid circles.Many physical properties of fiber such as gloss, wicking wet transmitting performance are all relevant with filamentary cross sectional shape.Can use physical method to change the cross sectional shape of synthetic fiber, give the fibre chemistry method the characteristic that can not obtain.Therefore, fiber heteromorphosis technology has obtained promotion and application rapidly since being born.
Cross has appearred in the continuous development along with production technology, w shape, triangle, the tencel that waits different shape of H shape.Be accompanied by the change in cross section, the feel of profiled filament, gloss, character such as hygroscopicity have all had bigger change.For example, the fiber of triangular-section has flash effect, and star section elasticity is better and have good moisture absorbing and sweat releasing, and the fiber of flat cross section can improve anti-pilling etc.At present, do not see the report of imitative cross ECDP/PET composite fibre.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of imitative cross ECDP/PET composite fibre is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of imitative cross ECDP/PET composite fibre is characterized in that, described fiber shape is imitative cross; At least 1 spinneret orifice is set on the described spinnerets; Spinneret orifice be shaped as imitative cross, be formed by connecting by the rectangle of marginal portion and the circle of mid portion; The long a of the rectangle of marginal portion is 0.5～10.5mm, and wide b is 0.2～8mm, and clearance C is 0.02～0.08mm; The interior diameter of a circle d of mid portion is 0.2～0.4mm, and the diameter D of cylindrical is 0.6～3.0mm; During composite spinning, the above-mentioned imitative cross spinnerets that adopts;
The fiber number of described composite fibre is 2.0～20dtex.
Compared with prior art, good effect of the present utility model is:
(1) the utility model adopts imitative cross fibre, and its single fiber fiber number is low, guarantee that degree of profile, bar do evenly fabrics feel soft; Increased hollow, when the groove that guarantees its cross section is constant, thereby guaranteed this fiber moisture absorption sweat discharging functions simultaneously, warmth retention property, pliability and bar are done uniformity and have been obtained tangible improvement;
(2) the utility model adopts composite spinning technology, introducing contains the ECDP component of flexible hydrophilic molecules chain, give fiber excellent antistatic and comfortableness, simultaneously in spinning process, because the temperature-responsive of two component various flows kinetic viscosities gives fiber permanent elasticity;
(3) the utility model utilizes existing equipment can carry out large-scale production, has enlarged economic benefit and social benefit.
