Description

The manufacture method of raised woollen blanket

The invention relates to two-sided napping and weight lighter through compiling the manufacture method of (longitudinal knitted) woollen blanket, the present invention especially about two-sided decorative pattern in the table, color is similar and the manufacture method of the raised woollen blanket that sense of touch and heat insulating ability are good.

With double helix compile that machine (ダ Block Le ラ Star セ ル Machine) is made into more softness and sense of touch are better than general fabrics through compiling (longitudinal knitted) woollen blanket (waiting fabric), except that Japan, more be widely used in all over the world.And the warp knitted blanket of commonly using is a double braid material of being compiled woven one-tenth by double helix, partly do middle the incision by its central fine hair (looped pile) yarn, become two pieces of (band) fine hair knitted or woven fabrics, the fine hair cloth of gained only is single face villous (band) fine hair knitted or woven fabrics, after thereby necessity such as again these single face fine hair knitted or woven fabrics are dyeed processing and fluffing, branch comb (eight I) processing are handled, again that two the inside is superimposed, and in its periphery sew up one piece of woollen blanket.

The two-sided superimposed woollen blanket of this kind, owing to constituted by two pieces of single face fine hair knitted or woven fabrics, its weight is bigger, be difficult to cater to the modern and liking the demand easily of using, and also uneconomical by the method for making that two pieces of single-side pile felt material are made into one piece of woollen blanket, be difficult to increase production in a large number woollen blanket with the double helix volume machine of some.

Japan's special permission bulletin 52-33719 communique once proposed the warp knitted blanket of two sides fine hair woollen blanket, though solved the partly problem of aforementioned double-layered woollen blanket, this is in light weight than duplex felt through the braiding woollen blanket, but, the floss loop bent portions of woollen blanket the inside handles because of being done the plucking fluffing, it is upright that filoplume is straightened, when plucking (draw and scratch I) operation and use, lose hair or feathers easily, and for preventing depilation, must use thicker fine hair double strand yarn (silk), and this wool yarn length is longer.But as when using thick, long wool hair double strand yarn, then must carry out repeatedly cropping and plucking processing by his-and-hers watches velvet wool yarn, make the tomentum on woollen blanket surface fully be pulled to the inside, therefore must add adjustment form the inside fine hair amount in addition, make its homogeneous.

In the manufacture method of fabrics such as above-mentioned woollen blanket, after cropping and plucking operation are several times carried out, though but the fine hair amount that the mat adjustment makes table the inside homogeneous as far as possible, because of desire will be grown and thick fine hair double strand yarn is pulled to the inside fully its difficulty is arranged, so how many fine hair amounts of woollen blanket the inside is less than the surface.And when cropping and plucking operation cost, the long wool hair ratio of woollen blanket the inside is easier to lodging, for preventing lodging, the young pilose antler of the inside need repeatedly be combed straight finishing, after this carry out cropping (suede) (シ セ-リ Application グ) and glazing operation again, the whole piece woollen blanket is taken a lot of work immeasurablely, uneconomical to finishing, and production efficiency is low.

The objective of the invention is to improve the disappearance of commonly using two-sided fluffing (fine hair) woollen blanket, and provide a kind of can the manufacturing table manufacture method of the identical and lightweight raised woollen blanket fabrics such as (felt) of the inside fine hair amount, another object of the present invention then is to provide the raised woollen blanket method of producing fabric such as (felt) of a kind of tool feature color and sense of touch.

For reaching above-mentioned purpose, in the manufacture method of woollen blanket of the present invention, compile machine with known double helix villus yarn 1 is inserted 2,2 of basic clothes through compiling, weave into double braid cloth 3 (with reference to figure one), villus yarn 1 can be natural or synthetic fiber or wherein any blend fibres such as polyacrylonitrile, wool, cotton, silk, cashmere (goat cashmere), nylon or polyester.The weight per square meter of fine hair 1 is generally height, and the filamentary fiber number that constitutes this villus yarn is following for good with 2 red Buddhist nuns (DI-ENER).Basis cloth 2 ties up to double helix and compiles machine interior warp-wise knitting yarn and broadwise yarn clipping (silk) formation with general polyester and nylon fiber long filament.

On the one hand, double braid cloth 3 promptly imposes continuous dip dyeing treatment (referring to figure six) before being cut by the centre; Processing mode is shown in figure six, it is pulled straight after being retained in the angle square 15,, send into pad dyeing roller (roller) 17,17 by the dipping tank 16 that contains staining solution, deliver in the steam box through 17,17 roll compacting, do the promotion of the staining reaction of certain hour in the decatize mode and handle.Thereafter this double braid cloth 3 is again through rinsing machine 19 washings and softening processing and dry to stablize its size.Then, with the cutter 30 of fine hair (looped pile) yarn of double braid cloth 3 shown in figure seven, cut from the centre, be separated into single face fine hair knitted or woven fabrics 4 (with reference to figure two), the position of cutting in the middle of it is shown in the dotted line a of Fig. 1.

The surperficial villus yarn 5 of the single face fine hair knitted or woven fabrics 4 (figure two) that make makes it separate fibre (dividing silk) fully through cropping processing and promptly forms villous surface 23 shown in figure three.With the inside fluffing of raising machine 24 (with reference to figure four) with basic cloth 2, after making its fine hairization, villous surface 23,25 is again through splitting (eight I), arrangement processing making woollen blanket cloth 26 (referring to Fig. 5), last again with Sewing machines will woollen blanket cloth 26 around sew up, promptly finish the woollen blanket of two-sided napping.

On the other hand, double braid cloth 3 also can directly be cut into single-side pile felt material 4 by the centre, and the surperficial villus yarn 5 of fine hair cloth 4 is machined to impose continuously after fully separating fibre (divide silk) to press down through cropping again and dyes (stamp) and handle.Double braid cloth 3 is preferably made the light color dip dyeing treatment in advance at this moment.Single face fine hair knitted or woven fabrics 4 in right-falling stroke is dyed as shown in Figure 8, cloth 4 temporary transient reservations are drawn out continuously by angle square 21, method with starching, make through compiling closely connected the right-falling stroke on the conveyer belt 22 that dyes machine 20 in basic cloth 2 surfaces and transport in half tone, in transporting the way via screen cloth decorative pattern version (the ス Network リ-Application type of a plurality of cutting apart (look)

) 8 right-falling strokes of the same colour in turn dye, and regularly promote staining reaction with decatize again in steam box 9 (referring to Fig. 9).The single-side pile felt material 4 of villous surface after right-falling stroke is dyed is after the timing decatize, again continuously as shown in figure 10 to wash softening processing, again tiltedly at all and the finishing of woven design bending and make tentering and handle, with hot blast chamber 13 cyclic dryings of pin tentering dryer 12 and stablize its size through cloth.With aforementioned same, the inside of basic cloth 2 promptly carries out fine hair two sides 23,25 is split and put in order processing to make woollen blanket cloth 26 (referring to Fig. 5) after 35～50% fluffing fine hairization.

Again, villus yarn 1 can use all prestained terry yarns.Do not remake dyeing after double braid cloth 3 is weaved at this moment and handle,, can be made into all the colorful one raised woollen blankets of two sides according to aforementioned same manufacturing process.

The present invention compares with the manufacturing of fabrics of layered blanket, and the production efficiency of woollen blanket greatly improves, and eradicates table, the apparent difference in the inside.Promptly make two-sided style fabrics such as raised woollen blanket much at one; Again, when making woollen blanket with method for making of the present invention, rare depilation situation when the tomentum of the inside is pulled out, no operatton ecological deterioration, the problem generation that produces Soft flocks when using.

The raised woollen blanket that the present invention makes (felt) is compared with fabrics of layered blanket, and it is in light weight, needn't use thick looped pile double strand yarn and long fine hair again especially.Therefore in the method for the present invention, the cropping of his-and-hers watches velvet wool yarn and plucking operation number of times also can pull to the villus yarn on woollen blanket surface the inside less, and the fine hair amount of adjustment form, the inside makes it be tending towards homogeneous easily.And the present invention is less because of the number of times of required cropping and plucking operation, the overall operation time shortens, in addition for the fine hair that prevents the woollen blanket the inside falls the dressing operation that Mao Erxu puts in order the filoplume comb of the inside also can be simple, its result, whole woollen blanket is finished institute and is taken time and energy and alleviate less expensive.
