Abstract

The invention discloses cotton, bamboo fiber and metal fiber blended yarn and a production method thereof, and the blended yarn comprises the following components by weight percent: 60-70% of cotton, 15-25% of bamboo fiber and 10-20% of metal fiber. As the cotton, bamboo fiber and metal fiber blended yarn simultaneously has the excellent characteristics of the cotton, the bamboo fiber and the metal fiber, the blended yarn can eliminate the respective defects of the three, and fabric produced by using the blended yarn has beautiful appearance, comfort and anti-radiation feature. The metal fiber is selected, thereby making up for the defects that the cotton and the bamboo fiber do not have the anti-radiation feature. The blended yarn of the three raw materials can lead the advantages of the three to complement each other, simultaneously make up for the shortcomings of harsh hand feeling of the metal fiber, and poor moisture absorption and air permeability, and finally determine the use of raw cotton and the bamboo fiber for blending. The blended yarn can simultaneously ensure the comfort of the use of the fabric produced by the blended yarn while realizing the functionalization of the yarn, and further has great market prospects.

Description

Cotton, bamboo fibre, metal fibre blended yarn and production method thereof

Technical field

The invention belongs to the spinning engineering field, relate to a kind of blended yarn and production method thereof, specifically, relate to a kind of cotton, bamboo fibre, metal fibre blended yarn and production method thereof.

Background technology

Cotton, bamboo fibre, metal fibre all belong to common spinning material, and their characteristic is as follows respectively:

Cotton fiber: (1) is alkaline-resisting and not acidproof; (2) intensity is good: cotton fiber powerful higher, and the dry state brute force is about 2.6-4.9CN/dtex, and the hygrometric state brute force is about 2.9-5.6CN/dtex, and brute force has rising slightly after the moisture absorption; (3) heat resistance is better, and light resistance is general, and the cotton fiber heat resistance is better, but not as terylene, acrylic fibers, but is better than wool, silk, approaches viscose.The cotton fiber light resistance is general, and as contacting with daylight for a long time, fiber strength can reduce, and concurrent cirrhosis is crisp; (4) poor flexibility, crease resistance is poor: cotton fiber elasticity is relatively poor, cotton fiber is thin and lack, and is soft, poor flexibility, when wearing with wash after wrinkling easily; (5) wear no resistance: ABRASION RESISTANCE is not outstanding, and cotton goods are not too endurable; (6) good hygroscopicity, good permeability, dyeability are good: cotton fiber has stronger wettability power, cotton garment moisture absorption, ventilative, and no feeling of oppression and heat does not have electrostatic phenomenon yet.Cotton fiber dyeing is functional, can dye shades of colour.

Bamboo fibre has following advantage: 1, antibacterial bacteriostatic function: harmful bacterias such as the Escherichia coli that will originally cultivate, staphylococcus, putting bacterium can multiply in cotton, xylon goods in a large number, in bamboo fibre fabric cloth last one hour, bacterium is killed 75% after having disappeared 48%, 24 hour.2, superpower health care: negative ion concentration is equivalent to the negative ion concentration content in field, countryside up to 6000/cubic centimetre in the bamboo fibre, makes human body feel more fresh and comfortable.3, humidity absorption and release function: the loose structure of bamboo fibre has good moisture absorption, moisture releasing function, thereby regulates the human body wetting balance automatically.4, deodorizing adsorption function: the inner special superfine pore structure of bamboo fibre makes it have powerful adsorption capacity, harmful substances such as formaldehyde, benzene, toluene, ammonia in the energy absorbed air, and eliminate smell.5, heat accumulation thermal function: the bamboo fibre far infrared transmissivity is up to 0.87, and heat accumulation thermal is better than the traditional fibre lining greatly.6, soft comfortable function: it is thin, soft that bamboo fibre has the unit fineness; Whiteness is good, color is beautiful; Toughness and ABRASION RESISTANCE are strong, and unique resilience is arranged; Stronger vertical and horizontal intensity and stable uniform are arranged, and drapability is good.Shortcoming: bamboo fibre is owing to its intrinsic fiber properties, and its intensity is not fine, so fastness is not fine; Alkali resistance is poor.

Metal fibre has chemical etchings such as good resisting chlorides, strong acid-base resistance, and metal fibre has granular and softnessization feature; The metal fibre feel is coarse, the shortcoming of moisture permeability difference.

More than three kinds of fibers all have separately merits and demerits, its fabric of making that spins separately also has corresponding advantages and shortcoming, so cause Application Areas narrow, relevant blended yarn and production method thereof is not arranged as yet at present, its advantage is concentrated, and elimination shortcoming separately.

Summary of the invention

The purpose of this invention is to provide a kind of new cotton, bamboo fibre, metal fibre blended yarn, make it to have both the overall merit of cotton, bamboo fibre, metal fibre blended yarn, eliminate their shortcomings separately simultaneously.Another object of the present invention provides the production method of this cotton, bamboo fibre, metal fibre blended yarn.

Cotton of the present invention, bamboo fibre, metal fibre blended yarn comprise following component according to mass percent: cotton 60～70%, bamboo fibre 15～25%, metal fibre 10～20%.

Preferably, cotton of the present invention, bamboo fibre, metal fibre blended yarn comprise following component according to mass percent: cotton 65%, bamboo fibre 20%, metal fibre 15%.

The quantitative 29.2g/5m of described metal fibre synnema, fibre length 40mm～50mm, fineness 60.5um, ultimate strength 3.0CN, resistance 20.68KN/m, percentage elongation is not less than 0.8%; Bamboo fibre 1.67dtex * 38mm, raw cotton 1.78dtex * 36mm.

The production method of cotton of the present invention, bamboo fibre, metal fibre blended yarn may further comprise the steps:

Raw cotton and bamboo fibre mix through opening picking, comb and parallel cotton fibers prior to spinning combing, in advance also, and after the combing slivering, by in the lump, two also, three and and the metal fibre synnema and and, and and ripe bar, and then be certain number yarn through rove, spinning-drafting, be rolled into conical bobbin yarn through winder again.

Cotton of the present invention, bamboo fibre, metal fibre blended yarn be because cotton, bamboo fibre, the metal fibre good characteristic that has possessed simultaneously eliminated self-defect separately, therefore the fabric made with blended yarn of the present invention have attractive in appearance, comfortable, the radiation proof feature.Selected metal fibre for use, remedied cotton, bamboo fibre can not radiation-resistant defective.Cotton, bamboo fibre have been selected for use, bamboo fibre is kind of a natural green formed material, have principal characters such as high ventilation, absorb-discharge humid and antibacterial bacteriostatic and initial modulus are big, in order to satisfy the requirement of high-grade fabric dress, remedied the defective of the little and bamboo fibre crimpiness difference of metal fibre initial modulus.Mutual supplement with each other's advantages of each group of three kinds of raw material blended yarns have simultaneously that to remedy the metal fibre feel coarse, and the shortcoming of moisture permeability difference is finally determined to carry out blending with raw cotton and bamboo fibre.Guarantee the comfortableness of the fabric use that blended yarn is made when realizing the resultant yarn functionalization, market prospects are good.

The specific embodiment

The present invention is further illustrated below in conjunction with embodiment, but the scope of protection of present invention is not limited to the scope that embodiment represents.
