Abstract
The invention discloses a coupling agent modifying method for bamboo fibers. The coupling agent is dissolved in absolute ethyl alcohol; bamboo fibers are added into a water bath of 50 to 70 DEG C, are uniformly stirred for 2 to 6 hours, and are subjected to vacuum drying for 8 to 16 hours, wherein the coupling agent is a silane coupling agent. According to the coupling agent modifying method for the bamboo fibers, which is disclosed by the invention, the bamboo fibers are treated by the silane coupling agent; the interface compatibility when the bamboo fibers are compounded with polypropylene is improved, so that the bamboo fiber polypropylene composite material is applied more widely.
Description
Technical field
The invention belongs to pin textile technology field, relate to a kind of processing method of bamboo fibre, be specifically related to a kind of coupling agent modified method of bamboo fibre.
Background technology
Bamboo fiber is a kind of brand-new natural fabric, and be the natural bamboo fibres that the method adopting physics, chemistry to combine is produced, natural bamboo fiber and bamboo pulp fiber are essentially different, and bamboo fiber belongs to natural fabric, and bamboo pulp fiber belongs to chemical fibre.Bamboo fiber succeed in developing the birth indicating another natural fabric, it meets national industry development policies.
The longitudinal smooth surface of bamboo fibre, homogeneous, there is the groove that many are more shallow; Cross section is close to oval, and edge is irregular.This surface texture makes bamboo fibre have certain cohesive force, is conducive to the resultant yarn of fiber.
Its cross section is the special construction of height hollow, can attract large quantity of moisture instantaneously and through a large amount of gas, and longitudinally straight, the hole that surface grooves is formed can produce stronger capillary effect, makes bamboo fibre have good humidity absorption and release performance.
Natural antibacterial ingredient in bamboo, can be combined on cellulose macromolecule all the time.So bamboo fiber also can not lose the anti-microbial property of its uniqueness through cyclic washing, Exposure to Sunlight.
Bamboo fibre contains chlorophyll copper sodium, makes its textiles have good deodorization, and chlorophyll copper sodium or safety, excellent ultra-violet absorber, can to a certain degree reduce the injury of ultraviolet to human body.Having experiment to show: the ultraviolet penetrance of bamboo fibre is 0.6%, is cotton 41.6 times.Bamboo fibre can 100% degraded, be Green Product.
Bamboo fibre and cotton fiber blending, can improve the performances such as the spinnability of bamboo fibre, pilling resistance, DIMENSIONAL STABILITY and sense of fullness, and give the silk quality sense of product uniqueness, gas permeability, drapability, flexibility, comfortableness.
Bamboo fibre and wool blendedly can produce frivolous dry-touch type fabric, product has that feel is smooth, elegant, the comfortable feature such as nice and cool of dangling, and be suitable for taking summer, what breach wool fabric takes limitation, enrich wool spinning fabric kind, improve fabric class and added value.
Therefore bamboo fiber products can be widely used in underwear, shirt, sportswear and infant-wear, especially summer various fashionable dress and the desirable fabric of the home textile product such as sheet, bed clothes, towel, bath towel.
Widely using of plastics, carrying capacity of environment is increased sharply, and natural composite material is subject to extensive concern.Bamboo-plastic composite material has the advantage of bamboo wood and plastics concurrently.The development & application of polypropylene (PP)/bamboo fiber composite material, can reach conservation resource, the object of protection of the environment, but there is the bamboo fibre of polar group and nonpolar PP interface compatibility poor, its composite is applied and is limited to.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of coupling agent modified method of bamboo fibre, to improve interface compatibility when bamboo fibre and polypropylene composite materials.
For achieving the above object, the invention provides following technical scheme:
A coupling agent modified method for bamboo fibre, comprises the steps:
Be dissolved in by coupling agent in absolute ethyl alcohol, add bamboo fibre, uniform stirring 2 ~ 6h, vacuumize 8 ~ 16h in 50 ~ 70 DEG C of water-baths, wherein, described coupling agent is silane coupler.
Preferably, the mass concentration of described coupling agent in absolute ethyl alcohol is 1 ~ 5%.
Further, the mass concentration of described coupling agent in absolute ethyl alcohol is 2%.
Preferably, described bath temperature is 60 DEG C, and the uniform stirring time is 3h.
Preferably, described bamboo fibre fineness is 100 ~ 300 orders.
Preferably, by bamboo fibre vacuumize 12h.
The coupling agent modified method of bamboo fibre of the present invention, with silane coupler solution process bamboo fibre, improves interface compatibility when itself and polypropylene composite materials, and bamboo fibre PP composite material is more widely used.

Embodiment 1
Silane coupler is dissolved in (mass concentration is 1%) in absolute ethyl alcohol, adds 100 object bamboo fibres in 50 DEG C of water-baths, uniform stirring 6h, vacuumize 8h, for subsequent use, carry out spinning after compound with pp.
Embodiment 2
Silane coupler is dissolved in (mass concentration is 5%) in absolute ethyl alcohol, adds 300 object bamboo fibres in 70 DEG C of water-baths, uniform stirring 2h, vacuumize 16h, for subsequent use, carry out spinning after compound with pp.
Embodiment 3
Silane coupler is dissolved in (mass concentration is 2%) in absolute ethyl alcohol, adds 200 object bamboo fibres in 60 DEG C of water-baths, uniform stirring 3h, vacuumize 12h, for subsequent use, carry out spinning after compound with pp.
In those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
