Abstract
The invention discloses radiation protection regenerated cellulose fiber knitted fabric and a knitting method thereof. According to the knitted fabric, by use of the organic arrangement and combination of triangles and knitting needles, a needle dial and a needle cylinder conduct knitting of single face plain stitches separately, nodes are relied on and interweaved in an overlapping mode for connection, and two layers of the single face plain stitches are connected to form a whole double-layer structure. The surface layer of the knitted fabric is made of blended yarns of radiation protection regenerated cellulose fiber and long stapled cotton, and the radiation protection function is achieved; the lining of the knitted fabric is made of ultraviolet-proof dacron, when the lining makes contact with the skin, the comfortable and soft effects are achieved, and the warm-keeping effect and good air permeability are achieved; the shell fabric interweaving portion is of a double-face rib stitch structure formed by the ultraviolet-proof dacron, the blended yarns of the radiation protection regenerated cellulose fiber and the long stapled cotton are uniformly hidden between the rib stitch structures in a floating thread mode, and the flatness of the fabric is good. Through the selection of raw materials, reasonable stitch structure and weaving and dyeing and finishing path, the warm-keeping effect and the air permeability effect of the knitted fabric are good, and the X-ray and ultraviolet light protection function is remarkably improved.
Description
Technical field
The invention belongs to textile product technical field, more specifically, relate to a kind of radiation proof regenerated celulose fibre knit goods and weaving method thereof.
Background technology
Extensively universal along with household electrical appliance such as mobile phone, computer and micro-wave ovens, particularly national defence scientific research, the developing rapidly of Radiation Medicine and atomic energy industry, the use of various ray is increasingly extensive.Long Term Contact electromagnetic radiation can produce larger injury to human body, and especially X-ray and ultraviolet harm also become increasingly conspicuous, and therefore according to the character of such ray and the mechanism of action with material thereof, produces and spins radiation knit product, become the bright spot of textile industry.
Existing radiation-proof fabric mainly contains following several mode: one applies one deck radiation protective layer on base cloth, and such formed radiation-proof fabric is airtight, and can not wash; One is embedded with metal fiber in fabric, and as silver-colored fiber, such time has been grown metal and has been easy to drop, impact effect, and should not wear next to the skin.
Radiation proof regenerated celulose fibre is added in viscose solution by X-ray screener-radiation proof barium sulfate powder to be prepared from, it not only remains, and viscose moisture absorption is breathed freely, advantage comfortable and easy to wear, but also there is X-ray shielding rate high (being greater than 65%), the advantage that persistence is good.And adopt the organic dispersion medium dissolved each other with water prepare due to the X-ray screener in radiation proof regenerated celulose fibre, therefore it mix more evenly with viscose glue, good dispersion in viscose, and during spinning moulding, barium sulfate loss is less.
Radiation proof regenerated celulose fibre has good textile process performance, can be used as radiation proof class fabric new material, but not yet for the exploitation of functional terminals textile fabrics.Therefore, how to utilize radiation proof regenerated celulose fibre and other fiber reasonably combined, adopt new reasonable fabric tissue, study and improve ripe weaving process, the knitted fabric that employing radiation proof regenerated celulose fibre is made into can play the functional of radiation proof regenerated celulose fibre, there is again good anti-ultraviolet function, heath-function and snugness of fit superior more than existing knitwear, this is technical problem urgently to be resolved hurrily at present.
Summary of the invention
First technical problem that the present invention will solve is to provide a kind of radiation proof regenerated celulose fibre knit goods, and for solving above-mentioned first technical problem, the present invention adopts following technical proposals:
A kind of radiation proof regenerated celulose fibre knit goods, is characterized in that: described knit goods is double-decker, and double-decker jacquard fabric feel is abundant, adds the warmth retention property of fabric, enhances X-ray-preventing effect; Described knit goods top layer is the blended yarn of radiation proof regenerated celulose fibre and long-staple cotton, plays radiation protection; Nexine is antiultraviolet terylene, and soft with skin contact comfort, heat-insulation breathable is good; ; Described top layer is connected by node with between nexine, described node is the two-sided rib stitch structure that antiultraviolet terylene woven is formed, the blended yarn of described radiation proof regenerated celulose fibre and long-staple cotton is evenly hidden in the middle of two-sided rib stitch structure with flotation line form, makes the flatness of fabric good.
Further, the line density of the blended yarn of described radiation proof regenerated celulose fibre and long-staple cotton is 18.2tex(Tekes), wherein the ratio of radiation proof regenerated celulose fibre and long-staple cotton is 70:30; The line density of described antiultraviolet terylene is 100D(DENIER)/144F(monofilament number).
Further, described node is circular; Further, the diameter of described node is 3mm.
Second technical problem that the present invention will solve is to provide a kind of weaving method of radiation proof regenerated celulose fibre knit goods.
For solving above-mentioned second technical problem, the present invention also provides a kind of weaving method of radiation proof regenerated celulose fibre knit goods:
Described weaving method utilizes organic permutation and combination of trigonometric sum knitting needle to make dials and syringe carry out the braiding of one side plain stitch separately, forms two single-sided structure: top layer and nexine; By Node connectedness between described top layer and nexine, top layer and nexine is made to connect into overall double-decker; Described node is the two-sided rib stitch structure that nexine yarn is woven into, and top layer yarn is evenly hidden in the middle of two-sided rib stitch structure with flotation line form.
Adopt the direct needle selection braiding of floral disc jacquard, odd number road penetrates (70/30) 18.2tex blended yarn of radiation proof regenerated celulose fibre and long-staple cotton; Even number road penetrates 100D/144F antiultraviolet terylene.
Further, the loop length of described knit goods is: odd number road is 260 ± 2mm/100 pin; Even number road is 290 ± 2mm/100 pin.
Further, described knit goods dry weight: 190 ± 10g/ ㎡; Described knit goods density: vertical close 105 lines/50mm, horizontal close 95 stringers/50mm.
Beneficial effect of the present invention is as follows:
The present invention passes through the selection of raw material and reasonable weaving structure, make knit goods except the moisture absorption remaining conventional viscose is breathed freely, except advantage comfortable and easy to wear, this product has very strong anti-ultraviolet function, UPF value > 40 after tested, and T(UVA) AV ﹤ 5%, reach the requirement of antiultraviolet product, can shielding of ultraviolet radiation effectively when wearing outside underwear, protection human body skin is healthy; Multiple field such as this fabric can be widely used in T-shirt, Sport & Casual clothes, family are spun; Double-layered jacquard fabric feel is abundant, adds the warmth retention property of fabric, enhances X-ray-preventing effect; In table, two-layer structure has once been weaved, and eliminates compound working procedure, reduces cost, and wears well-pressed, and after washing, wrinkle resistance is good; The yarn of textile surface floats the long inside being all hidden in this two-layer fabric, makes decorative pattern can not because of kerf, fluffing and damaging; Because the raw material of table, inner two shell fabrics is different, dyed color is different, fabric is made to have special color effect.
