Description
Technical field
The invention belongs to technical field, relate to anti-perspective composite fibre of a kind of tangerine lobe and preparation method thereof.
Background technology
The technological innovation developing into traditional textile industry of functional fibre, fibre in differentiation and high-performance fiber, the conversion to high-tech industry creates advantage, for mankind's growth in the living standard contributes.Functional fibre refers to except the physical and mechanical properties that general fiber has, and also has the tencel of certain specific function, is the fiber meeting certain particular/special requirement and purposes, and namely fiber has certain specific physics and chemistry character.The output of conventional chemical fiber can satisfy social needs substantially, but also has many deficiencies in performance, can not meet consumer demand.Such as, all need to be improved some function of fiber taking in the physiological comfortableness of fiber wearing process, the comfortable and convenience of human motion process, security and durability and environmental protection.Such as: fiber has health care function (antibacterial, kill mite, physiotherapy and eliminate the unusual smell); Safeguard function (radiation proof, antistatic, uvioresistant etc.); The wet comfortable function (heat absorption, heat release, moisture absorption, moisture releasing etc.) of heat; Medical treatment and environment-friendly function (biocompatibility and biological degradability).
The most basic performance requirement of textiles is " resisting cold " and " covering body ".So-called " covering body " is exactly require that textiles has good perceptual masking performance.There is not perceptual masking problem in dark heavily fabric, but summer light color cloister fabric, particularly white facestock ubiquity underwear and body skin expose problem to the open air, cause dressing person's outward appearance indecency, easily cause the embarrassment that underwear and skin easily expose.As pressed international practice, naval officers and men should wear white uniform in summer, and for avoiding the underwear of white garments to expose problem to the open air, the heavily fabrics such as naval of various countries many employings polyester-cotton blend chafer duck take fabric as the summer, and comfortableness is poor.Some naval of African country, selects more frivolous fabric, but underwear exposes to the open air seriously, sack cloth exposes to the open air obviously, object is shown in pocket, affects soldier's discipline, appearance and bearing style and features.Naval's colour prime white clothes of China previous generation are had to install lining additional or are added and wear terylene and spin underpants and expose to the open air to avoid underwear and body skin, but snugness of fit is very poor; Also have in curtain and masking material field, also need privacy and the light temperature modulability of protecting room with the textiles that anti-perspective is effective.Except naval's shirt, jumper, customs's uniform, medical personnel's uniform etc., because the usage of trade or international practice are also generally white, dark color can not be adopted, thick and heavy fabric solves perspective problem, solution of can only starting with from fiber, yarn and the aspect such as fabric construction and coating thereof.
Can reflect after light is irradiated to textiles, absorb, scattering, refraction and transmission, the reverberation after the light of wherein transmission arrives target object experiences same process at textiles reverse side.The Research Thinking realizing textiles perceptual masking effect is, increases textiles as much as possible to the reflection of visible ray, absorption, scattering, reduces the light quantity through textiles.Concrete methods of realizing can comprise the change of fibre section shape, the setting of fabric construction parameters, the interpolation, coating Final finishing etc. of related auxiliaries.Prior art mainly carrys out anti-perspective by coating hindlimb unload, and for taking textiles, coating Final finishing affects its snugness of fit, as the impact etc. on gas permeability.The regulating degree of adjustment to this property of fabric vision of Final finishing and fabric construction is limited simultaneously, and durability is not enough.
Summary of the invention
Technical problem to be solved by this invention is to provide anti-perspective composite fibre of a kind of tangerine lobe and preparation method thereof.The present invention adds some particles in the preparation process of chemical fibre, increases reflection, scattering or absorption, or realizes the increase of reflection, scattering, absorption simultaneously, reduce the transmission to visible ray.Relative to after-finishing of textile products method, better from fibrous raw material modification durability.Simultaneously, invention also contemplates that the spinnability of fiber and the performance issue of fiber, too much spinning technique and fibre property will inevitably be had influence on because inorganic particulate adds, cross and there is no effect at least, therefore have employed the tangerine lobe spinning of particular design, make, in inorganic particulate ordered set, both to have reached the effect obstructed the light well, there is again good spinnability, and substantially do not affect the mechanical property of fiber.
