Abstract

The present invention relates to one kind of bamboo fiber knitting fabric with blended bamboo fiber yarn as facing layer and spandex or chinlon yarn covered with the bamboo fiber. It features that the blended bamboo fiber yarn consists of bamboo fiber in 50-70 wt% and cotton, Modal, Tencel, wool, cashmere or Dacron in 30-50 wt%, and has count of 20-60 s and twist multiplier of 330-345. The bamboo fiber knitting fabric has the excellent performance of bamboo, including moisture absorption, permeation, health care and antibiotic property, etc. as well as improved costume performance and size stability, and is one kind of high grade comfortable material for underwear.

Description

A kind of bamboo fiber knitting fabric

Technical field

The present invention relates to a kind of is face with the bamboo pulp fibre blending yarn, and spandex or other yarns are the bamboo fiber knitting fabric that nexine covers tissue.

Background technology

Bamboo fibre, as its name suggests, its base stock comes from the evergreen plant bamboo of the Nature, is the another regeneration green cellulose fibre of China after the success of independent development soybean fiber.Jilin chemical fibre group Hebei lucky ligusticumic FCFC takes the lead in having developed bamboo pulp fiber-nandina, and obtained national inventing patent " bamboo wood is produced the technology of cellulose viscose pulp ", the hygroscopicity that bamboo fibre has, gas permeability and drapability, all be better than the COTTON FABRIC product, the more important thing is its natural antibacterial in addition, the bacterium of same quantity is examined under a microscope, bacterium on the cotton products does not change, and the bacterium on the bamboo fibre is killed about 75% after 24 hours, and this is that other textile raw materials are incomparable.

The anti-microbial property inspection of table 1 bamboo fibre

As can be seen, cotton fine wet strength does not reduce, and slightly improves than doing by force of it on the contrary from the table; And bamboo fibre is quite different, and the wet strong of it reduced by 50% more than by force than dried, and be similar with viscose.

From " design feature of bamboo fibre and performance evaluation " as can be seen, though bamboo fibre itself has the moisture permeability above other fibers, and premium properties such as natural antibacterial, but because the low-intensity of pure bamboo fibre, give knitting weave, dyeing and finishing brings very big difficulty, makes the big heavy discount of wearability of its knitted fabric.

Summary of the invention

The objective of the invention is to adopt the blending by a certain percentage of other fiber and bamboo fibre, under the prerequisite that reaches the every premium properties that guarantees bamboo fibre, improve the wearability and the DIMENSIONAL STABILITY of lining.

The blending rate of bamboo fiber blended yarn of the present invention is with bamboo fibre 50-70%, and the blending composition of all the other 30-50% has: cotton, Mo Daier (Modal), day silk (Tencel), hair, cashmere or terylene, the blended yarn yarn count is 60-20 ^S, twist factor is 330-345, uses bright and beautiful close spinning technique spinning, it is few that the yarn that spun of the close spinning technique of brocade has a filoplume, powerful high characteristic, the fabric of making have that cloth cover is bright and clean, neat and well spaced, the characteristics of good permeability, and can effectively prevent the characteristic of fabric and the easy balling-up of cellulose fibre.The close spinning technique of brocade is on fine spining machine spun yarn, doubling, the three process of twisting thread to be united two into one, he with two rove with the parallel feeding draw zone of certain spacing, directly twist folded yarn in the same way in front roller the place ahead, and at front roller application filoplume aggregation equipment, some edge fibers are twisted with the fingers in the single thread near the trigonum that makes, thereby the minimizing filoplume reaches wear-resisting, the anti-fluffing of fabric, balling-up.With bamboo fiber blended yarn and other fiber yarn knitting needle knitted fabrics, as: spandex, polyamide fibre, use the happy single face loom of 24G moral, spandex or polyamide fibre are preceding, bamboo fiber blended yarn covers on spandex or the polyamide fibre yarn bamboo fiber blended yarn single face in the back synchronously.

Knitting needle knitted fabric of the present invention has following having a few:

1. have sucting wet air permeability and health properties

The spinning process of natural bamboo fibres and viscose glue are produced roughly the same, be difficult to distinguish from its surface, but on its cross section, can clearly see and have a large amount of fine pores, this structure makes fiber have natural sucting wet air permeability, in addition, because bamboo fibre contains the close and pectin composition of bamboo, this composition is useful to skin health, so it has health care again.

2. the anti-microbial property that has natural bamboo fibres

Knitting needle knitted fabric of the present invention is nice and cool except that having, the advantage of moisture absorption, ventilative, perspire, it also has the natural antibacterial characteristic simultaneously, this is by existing in the natural bamboo fibres body, inherent natural antibacterial composition " bamboo quinone " decision.Because " bamboo quinone " exists, make bamboo in the environment of the Nature, can keep free from insect pests, not go rotten.The anti-microbial property of natural bamboo fibres has passed through at present the detection that association is checked in Shanghai preventive medicine research institute, SGS, Japan's weaving, also confirms this point.

According to test center of China Textile Academy assay, the antibacterial value of knitting needle knitted fabric of the present invention is 4.22, and sterilizing value is 1.88, and (antibacterial value＞2.0 expression test sample books have fungistatic effect.Sterilizing value＞0 expression test sample book has bactericidal effect).

The yarn property test, same yarn count different components yarn " single thread ultimate strength " contrast is as follows:

Yarn count: 40 ^S

The composition of yarn	Bamboo 60%+ cotton 40%	Bamboo 70%+M30%	Wash 30%+ bamboo 70%	Bamboo 100% (object of reference)
