Description

One grows flax composite fibre and preparation method thereof

Technical field

The present invention relates to one to grow flax composite fibre and preparation method thereof, be specifically related to a kind of fibrous material utilizing the three-dimensional or meldable fibre compound of linen fibre and polyester fiber or hollow to be prepared into, belong to textile fiber material processing technique field.

Background technology

Since 20th century, chemical fibre start along with the development of macromolecular material produce.The appearance of chemical fibre, changes the mankind for thousands of years only using the history of natural fabric as unique textile fiber material, and opens wide prospect for obtaining new, that performance is more superior textile fabric.Recent two decades comes, and the chemical fibres industry of China achieves and develops fast, and according to the data of official website, within 1985, China's chemical fibre output is 104 tons, within 2007, is 2,457 ten thousand tons.Because natural fabric development limits by natural conditions, and chemical fibres industry limits less by natural conditions and can carry out modification according to different demand, estimates that new chemical industry fiber will continue development.

Polyester fiber (polyester fibre), in China also known as terylene, is by the synthetic fiber of the polyester of organic dibasic acid and dihydroxylic alcohols polycondensation through spinning gained.Shortcomings such as there is moisture content is low, poor air permeability, dyeability are poor, easily balling-up fluffing, easily contamination compared by terylene with natural fabric.In order to improve these shortcomings, often take the method for chemical modification and physical deformation.By certain modification, can reach improve fiber hydroscopicity, antistatic and anti-stain characteristic energy, improve fiber flame resistance and or ANTIPILLING ability etc. object can be improved, the range of application of modified polyester fiber is increased greatly.

Hollow is three-dimensional, also known as 3-D crimped fiber, it is turbulization when utilizing polymer melt to extrude, the principle of internal stress inequality and reach rolled efficiency, this by polymeric inner structure produce permanent be crimped onto stressed stretching after still can recover, there is resilience high, the advantages such as good hand touch, it is traditional crimped polyester, polypropylene fibre, polyamide staple fibre is incomparable, can be used for pillow, mattress, cover, bedcover, sleeping bag, down jackets, the stuffing of the article such as sofa, also can the PET Hollow short fiber of substituting import one, there is certain market capacity, there is higher surcharge.

Hot melt adhesive flax composite fibre is that one is heated to 110 ~ 150 DEG C, the core-skin of cortex and fusible bonding or parallel construction fiber, it still can keep fiber shape after processing, evenly efficient melting bonding is only carried out in the crosspoint of fiber, just can obtain softness, the non-weaving cloth that fluffy, good penetrability, tearing strength are high, be therefore produce important source material that is slim and bulk type non-weaving cloth.Due to adopt thermal bonding technology instead of chemical adhesive, therefore have nontoxic, pollution-free, energy ezpenditure is low, equipment investment is few, speed of production advantages of higher.This technique just adopt by more and more Duo Di producer.

Flax is one of natural fabric of using the earliest of the mankind, apart from the history of modern existing more than 10,000 years, there is temperature adjustment, antiallergy, antistatic, antibacterial function, and hygroscopicity is better than many fibers, can absorb the moisture being equivalent to own wt 20 times, therefore sodolin feel is dry and comfortable.Having many uses of the fabric that linen fibre is made is general, can be used as the industry articles for use such as garment material, drapery, tablecloth, bedding and Automobile Products.Linen fibre is a kind of rare natural fabric, and price is higher, and mechanical performance is strong not, and can not meet consumer demand, therefore, flax complex fiber material is development trend.

CN200910062083.6 discloses a kind of linen fibre and cotton fiber mixed yarn manufacturing technique, raw material comprises the multiple fiber of linen fibre, manufacturing technique comprises blowing, comb and parallel cotton fibers prior to spinning, drafting, rove, spinning process, be prepared into multicomponent blended yarn, technique is more complicated, and easily there is the problems such as the not high and cost of spin-drawing intensity is higher, restrict its application; And CN201310189209.2 and CN201310194427.5 individually discloses the blended yarn of a kind of cotton fiber, linen fibre and viscose and the blended yarn of a kind of bamboo fibre, linen fibre and acetate fiber, be only the simply composite of several fiber, if make the filler of bedding, can not directly clean, or cleaning post-concentration is agglomerating, affects later use.
