Description

A kind of " C " font bamboo carbon mixed ester fiber

[technical field]

The utility model relates to the fibre technology field, specifically, is a kind of " C " font bamboo carbon mixed ester fiber.

[background technology]

Bamboo wood is the important forest reserves of China, and its growth is fast, can become a useful person in a short time, and power of regeneration is strong, once afforests successfully, sustainable felling utilization.Bamboo wood was mainly used to make aspects such as farm implements, fuel, furniture, commodity, handicraft, construction material, floor and papermaking in the past, and value is low.

Along with science and technology development, domestic employing bamboo is fired bamboo charcoal, has enlarged its Application Areas greatly.Bamboo carbon forms through nearly thousand degree high-temperature firings, the fine and closely woven porous of its molecule, specific area can reach 485m2/g, has superpower adsorption capacity, and produces anion and releasing far infrared, can purify air, remove poison and inhale flavor, eliminate peculiar smell such as formaldehyde, benzene, and can intercept electromagenetic wave radiation, promote blood of human body circulation and metabolism, allaying tiredness.Bamboo carbon extensively applies to life, environmental protection, building, electronics, agricultural, chemical industry, medicine and other fields after science processing is refined.Bamboo carbon can be summarized as nine big functions: 1, absorption; 2, releasing far infrared; 3, produce anion; 4, separate out trace element; 5, control microbial reproduction; 6, regulate crop growth; 7, expelling parasite sterilization; 8, anti-oxidant; 9, electrostatic screen and anti-electromagnetic radiation.

Because the characteristics of the macromolecular conformation of PTT (being meant polytrimethylene terephthalate) and the lattice conformation of polymer chain, the elongation at break of fiber is greater than all fibres except that spandex.The percentage elongation of PTT is moderate, and its suitable elastic performance is suitable for the requirement of people to elastic fabric.The elastic recovery of PTT is better than PBT, more is better than PET.Compare with the outstanding rigidity of polyster fibre and goods, the feel of ptt fiber and fabric can be given the soft and comfortable sensation that approaches nylon.Add the good drapability and the suitable elasticity of fabric, for the fashion designer provides design inspiration and more wide space of thinking.The synthetic fiber disperse dyeing only just can be dyed dark color more than vitrification point.The vitrification point of PET is about 70～80 ℃, and owing to its degree of crystallinity height, compact structure, dye molecule are difficult for entering fibrous inside.So PET only when pressurizeing or having carrier, temperature to be about 130 ℃, could dye dark color with DISPERSE DYES.And the glass transition temperature of PTT is lower than PET about 46 ℃～65 ℃, so its dyeability is better than PET, can be under DNAcarrier free situation, and boiling dyeing at normal pressure.Simultaneously, under identical dyeing temperature, the length of penetration of dyestuff in PTT is apparently higher than PET, and color and luster is even, the fastness height.So not only can the fuel savings and the energy, can also reduce the content of chemical substance in the sewage simultaneously, the pollution on the environment degree reduces relatively, has tangible economic benefit and environmental benefit.Because these advantages make ptt fiber have bigger development and application prospect than PET fiber.By adjusting suitable spinning process condition and process for cooling condition, make the bamboo carbon ptt fiber product that meets specification requirement.

In recent years, people require more and more higher to comfortableness, health, security and the feature of environmental protection etc. of garment material, along with people's increase of activity time out of doors, the functional trend that interpenetrates with motion shape and combine together also is subjected to consumers in general's favor day by day, the lining of these class clothes, both required good comfort, required again when movable heartily, simultaneously relatively environmental protection with healthy.

Chinese patent publication number CN1272560 discloses composite antibacterial fibre, its preparation method and utilization thereof, the utility model discloses a kind of composite antibacterial fibre, it is double-deck core skin structure, its center core layer is that polypropylene material, cortex are polythene material, contains 3 ‰～10% nanometer-level silver source power in the cortex gross dry weight in said cortex polythene material; The preparation method and the utilization thereof of this composite antibacterial fibre are also disclosed.Product of the present utility model can broad-spectrum antiseptic, and it is long-lasting, washability, stability, security, product having enhanced antibacterial action, and has taken into account the pull resistance and the resilience of product.
