Abstract
The invention discloses a preparation method of raw bamboo fiber needled-punched felt. The raw bamboo fiber needled-punched felt is prepared by 30-95wt% of raw bamboo fiber and 5-70wt% of chemical fiber through opening, mixing, carding, lapping, needling, hot rolling and sizing procedures in sequence, wherein the carding procedure includes: the opened and mixed raw bamboo fiber and chemical fiber are fed into a carding machine for carding, so as to form a fiber web, the feeding line speed is 0.5-1.5m/min, the feeding fiber amount is 2-4kg/m<2>, the main cylinder frequency of the carding machine is 400-800rpm/min, and the room temperature in the carding procedure is controlled to be 15-28 DEG C and relative humidity is controlled to be 60-90%, so as to effectively prevent raw bamboo fiber smash and breakage, thus solving the problems that the raw bamboo fiber is difficult to card and the formed web is not even in the prior art. By the method of the invention, the raw bamboo fiber needled-punched felt with evenly formed web, smooth surface, good antibacterial action and air permeability, and strong absorbability can be prepared.
Description
Technical field
The present invention relates to non-weaving cloth and make the field, specifically be meant a kind of preparation method of raw bamboo fiber needled-punched felt.
Background technology
Nomex in that non-woven field is made with the acupuncture technology was mainly used in the flue gas ash removal field in the past.In recent years along with the nonwoven needled technology is used constantly development, its application at the family expenses field of textiles is also very extensive, as be used for indoor ornamentation, clothes liner, shoemaking etc., its structure mainly is based on individual fiber structures, and form the Nomex or the sheet material of different grammes per square metres and thickness, used fiber is generally chemical fibre, and its anti-microbial property, permeability and moisture pick-up properties aspect are all relatively poor.
Bamboo fibre has excellent anti-microbial property, permeability and hygroscopicity, and the present fiber that with the bamboo is raw material are made has been applied to the every field of textiles.Bamboo fibre can be divided into bamboo pulp fiber and bamboo fiber, and bamboo pulp fiber claims regenerated bamboo fiber, bamboo viscose again.Bamboo pulp fiber adopts chemical method to make.Promptly be raw material, the content of first kind fiber brought up to more than 93%, adopt hydrolysis one alkaline process (multistage bleaching), be refined into the bamboo pulp that can satisfy production requirement, then by dissolution of sodium hydroxide, through spinning, technology such as solidify and make through artificial catalysis with the bamboo wood.Bamboo fiber claims natural bamboo fibres again.The mao bamboon or the bamboo of clustering that normal employing is produced are raw material, natural bamboo pole is sawn into production goes up needed length, length can be determined in process of production according to purposes, to satisfy and other chemical fibres or natural fibre blended needs, adopt the method for machinery, physics then, by digestion, multiple working procedure such as softening, remove impurity such as lignin, pentosan, bamboo in the bamboo is glutinous, pectin, the direct primary fiber of extraction from bamboo pole.This fiber does not contain chemical addition agent in acquisition process, be a kind of pure natural fiber of real meaning.
Because the bamboo fiber filament strength is low, thickness is uneven, frangible, cause the combing difficulty, become net inhomogeneous, these problems have restricted bamboo fiber and have developed in the acupuncture The Application of Technology.
Summary of the invention
The objective of the invention is to overcome bamboo fiber provides a kind of raw bamboo fiber needled-punched felt in the technical all difficulties of acupuncture preparation method.
In order to address the above problem, the present invention adopts following technical scheme:
The preparation method of raw bamboo fiber needled-punched felt is with the bamboo fiber of 30-95wt% and the chemical fibre of 5-70wt%; Successively by shredding, mixing, combing, lapping, acupuncture, hot rolling and shaping process are made; Wherein, the combing operation is: shredding, the bamboo fiber that mixes and chemical fibre feeding carding machine are carried out combing, form fibre web, the feeding linear speed is 0.5-1.5m/min, and the feeding fibre weight is 2-4kg/m
2, the main cylinder frequency of carding machine is 400-800rpm/min, and indoor temperature is controlled at 15-28 ℃ in the combing operation, relative humidity is controlled at 60-90%.
Above-mentioned bamboo fiber and chemical fibre fineness are 1-4D, and length is 25-76mm.
Above-mentioned chemical fibre is one or more the mixture in polyester fiber, polypropylene fiber, the acrylic fiber.
Above-mentioned lapping operation is: the fibre web that obtains through combing is overlapped onto grammes per square metre 200-450g/m repeatedly
2
Above-mentioned acupuncture operation is: the fibre web after the lapping is carried out pinprick reinforcement, sting in advance earlier, main up and down again acupuncture is by forming the plain felt of acupuncture after the main acupuncture up and down; Depth of needling is controlled at 5-12mm, and needling density is controlled at 200-400 pin/cm
2, the fibre web draw ratio is controlled at 3-10%.
Above-mentioned hot-rolled process is: the plain felt that acupuncture is good carries out hot rolling, and hot-rolled temperature is controlled at 150-160 ℃, and the thickness of controlling plain felt is at 1-2.5mm.
Above-mentioned shaping process is: use framing shaping machine that the plain felt of hot rolling is carried out HEAT SETTING, setting temperature is controlled at 150-160 ℃, and shaping time is 4-8min.
After adopting technique scheme, the preparation method of raw bamboo fiber needled-punched felt of the present invention, in the combing operation, indoor temperature is controlled at 15-28 ℃, and relative humidity is controlled at 60-90%, and control feeding linear speed is 0.5 to 1.5m/min, and the feeding fibre weight is 2-4kg/m
2, the main cylinder frequency of carding machine is 400-800rpm/min, can effectively prevent the broken fracture of bamboo fiber like this, thereby solves bamboo fiber combing difficulty in the prior art, the uneven problem of one-tenth net.By the inventive method can produce into net evenly, smooth surface, anti-microbial property is good, permeability is good, moisture pick-up properties is strong raw bamboo fiber needled-punched felt.Raw material according to selecting the different blended composition and division in a proportion also can be made into the Nomex with varying strength characteristics; And the inventive method flow process is short, realizes than being easier to.
