Abstract

The invention relates to a tufting carpet prepared from sisal fiber. The preparation method thereof comprises the following steps: soaking sisal fiber in a water solution containing sodium hydroxide 1 to 10% the weight of sisal fiber and having a temperature of 70 to 100 DEG C and an amount of 10 times the weight of sisal fiber for 30 to 90 min, washing with clean water to adjust the pH value to 7 to 7.2, spin-drying and oven-drying to reduce the water content to 7 to 12%; oven-drying, and combing while sprinkling a special softening agent with an amount of 10 to 20% the fiber weight; and spinning the sisal fiber to yarn less than 0.9 counts, and processing to tufting carpet by a tufting machine. The novel environment-friendly carpet prepared from pure natural sisal fiber has the advantages of good third dimension, good elasticity and good flexibility, and can be used for jacquard and printing. The carpet is not easy to be bitten by insect, and has no harm to human health.

Description

The preparation method of sisal hemp tufted carpet

Technical field

The present invention relates to a kind of tufted carpet, particularly a kind of is the preparation method of the tufted carpet made of raw material with the sisal fiber.

Background technology

At present carpet on the market mainly by artificial fibre, chemical fibre, wool, velvet, cotton yarn and blend fibre through tufting, flocking, braiding or knitting and make.Also occur the sisal hemp carpet woven that adopts sisal fiber to make in recent years, and belong to pure natural substance as the sisal fiber of novel pavement, have the characteristics of ecological, environmental protective and return Piao and return genuine style, more and more be subjected to more consumers' welcome, be subjected to the favor of developed country especially deeply.But also there is following defective in it: 1. because the sisal fiber content of lignin is very high, sisal fiber is not only thick but also hard, adopt traditional treatment process to handle sisal fiber and can not spin spun yarn less than 0.9, yarn is hard, the uniformity is poor, therefore manufacturing requirements is than higher, and at present domestic only have 6～7 families can produce the sisal hemp carpet woven; 2. sisal hemp carpet woven outward appearance is flat, texture is stiff, elasticity is not good, feel is not well, and the pattern dullness, and aesthetic is undesirable.

On Hanoverian, Germany " world's carpet fair ", India has showed a kind of sisal hemp flocked carpet, welcome by travelling trader and market, and has caused the attention of domestic manufacturers at the beginning of 2008.The sisal hemp flocked carpet that India shows is having certain advantage than sisal hemp carpet woven aspect solid, level, the pattern.But flocking is difficult to fixing extensive sisal fiber, the sisal fiber integral body of erectting must be cemented just to be unlikely to come off, from and cause carpet more stiff, have no elasticity, therefore only be fit to do the doormat use.

Having not yet to see relevant is that raw material adopts tufting to produce the relevant report of sisal hemp tufted carpet with the sisal fiber.

Summary of the invention

It is the preparation method of the sisal hemp tufted carpet made of raw material with the sisal fiber that technical problem to be solved by this invention provides a kind of.

The present invention solves the problems of the technologies described above with following technical scheme: the preparation method of sisal hemp tufted carpet of the present invention is operated according to the following steps:

1) sisal fiber being put into temperature is that 70 ℃～100 ℃, weight are that the water of 10 times of amounts of sisal fiber soaks, and adds 1%～10% the NaOH that weight is sisal fiber weight, and soak time is 30～90 minutes; Soaking the back, to wash sisal fiber to pH value with clear water be 7～7.2, then drying dry again to the sisal fiber moisture be 7%～12%;

2) with 1) sisal fiber after handling carries out combing, spray special-purpose softener in the carding process, make yarn submissiveer, so that be fit to tufting machining, the consumption of special-purpose softener is 10%～20% of a sisal fiber weight, and the preparation method of special-purpose softener (this product has been applied for patent on June 19th, 2008 to State Intellectual Property Office) is:

Get following raw materials in portion by weight: 5 parts in 3～6 parts of potassium oleates, 2～7 parts in bobbin oil, 1～3 part of linen softening oil and water; Preparation technology is: potassium oleate, bobbin oil, linen softening oil and water are added under stirring in order expect can make special-purpose softener product to emulsion;

3) sisal fiber after the combing is spun into less than 0.9 count yarn, with tufting machinery it is stood at last and be made into sisal hemp tufted carpet on the base fabric.

Above-mentioned 3) needle gage of the tufting machinery that uses in the step preferably changes 5～8mm into.

Sisal hemp tufted carpet of the present invention is that a kind of fiber that adopts the pure natural sisal fiber to make combines with base fabric firmly, the stereoscopic sense by force, good springiness, soft, both can jacquard weave also can stamp the novel environment friendly carpet.It not only has the similar outward appearance of wool carpet, and have the same colourful of chemical fibre carpet, but it can the woolliness carpet easy being damaged by worms like that, also can as chemical fibre carpet, not be good for by easy harmful to human, its elastic effect is better than above-mentioned two kinds of carpets.

The specific embodiment

The content of sisal fiber lignin is very high to be the big principal element of fiber stiffness, and therefore decomposing the part lignin is the effective ways that improve the sisal fiber pliability.Concrete measure of the present invention is: in weight is to put into sisal fiber again after ten times of amounts, water temperatures of sisal fiber are to add 1%～10% NaOH of sisal fiber weight in 70 ℃～100 ℃ the water to soak 30～90 minutes, with clear water sisal fiber is washed till neutrality then, be that pH is 7～7.2, again with centrifuge get rid of put into behind most of water drying room dry to the sisal fiber moisture be 7%～12%.

In order to make the sisal fiber yarn submissiveer, so that can carry out tufting and jacquard weave operation smoothly, therefore also the sisal fiber of above-mentioned processing need be sent between the reason barrow and carry out combing, sisal fiber need spray 10%～20% special-purpose softener of sisal fiber weight at carding process, and then with the sisal fiber of the combing sisal hemp tufted carpet with the invention of tufting machining cost after the spinning workshop is spun into less than 0.9 count yarn.Though reaching tufting, the sisal fiber yarn that draws after the processing produces required pliability and compliance, but relative wool of its lines or artificial fibre, still bigger, 0.6～0.9 yarn is generally arranged, and the needle gage of existing tufting machining equipment generally only has 3.5～4mm, therefore needing the needle gage of adjustment Tufting machine is the tufting production that just can carry out sisal fiber about 5～8mm, the sisal fiber yarn can be stood on be made into sisal hemp tufted carpet of the present invention on the base fabric.

The preparation method of the special-purpose softener that sprays in the above-mentioned carding process is:

Preparing the required raw material of special-purpose softener is by weight ratio: 5 parts in 3～6 parts of potassium oleates, 2～7 parts in bobbin oil, 1～3 part of linen softening oil and water.

The preparation technology of special-purpose softener is: potassium oleate, bobbin oil, linen softening oil and the water of said ratio is added under stirring in order expect can make special-purpose softener product to emulsion.

Because the sisal fiber raw material that the present invention adopts can make its yarn submissiveer after treatment, be fit to tufting machining, the carpet feel of making is comfortable.
