Description

DETAILED DESCRIPTION OF THE INVENTION In producing a natural fur-like knitted fabric, the present invention involves mixing fibers corresponding to the "sash" and "cotton" of animal fur into the single fibers during spinning, and As “cotton hair” 1. Using sea-island structure fibers that are ultra-fine fibers with an ODR (denier) or less, a pile fabric can be easily constructed using the conventional flocking method or pile knitting method, and then treated with sea-removal ingredients to create a natural fur-like fabric. The present invention relates to a method for producing a knitted fabric having a unique texture, luster, and color tone.

Conventionally, pile or seal knitted fabrics have been produced as pseudo-fur, but these knitted fabrics either do not have the "pile" and "cotton hair" that are characteristic of animal fur, or even if they do, they do not have Because of the imperfections, only knitted fabrics with a feel completely different from animal fur could be obtained.

In other words, conventional pseudo-fur fabrics use straight filaments for the ``sash'' part and crimped yarns or heat-shrinkable filaments for the ``cotton hair'' part, which are intertwisted and knitted. As you can see (core spun yarn is made by using filament yarn as the core and short fibers for spinning as "cotton hair", and after using this fiber for pile yarn, it is cut to make fur-like fibers) Examples include knitted fabrics with length distribution.

Also, JP 46-2782, JP 49-116370
There are also ultra-fine napped fabrics with a thickness of 1.Odr or less, but as in the present invention, "sashimi" and "cotton hair" are composed of single fibers, and fibers with a diameter of 1.Odr or less are used as "cotton hair". At present, there is no way to easily obtain a knitted fabric with a unique natural fur-like texture and luster using conventional techniques.

Originally, animal fur has a small number of ``sash hairs'' and a thick layer of ``cotton hairs'' surrounding them, and the ratio of the number of ``sash hairs'' to ``cotton hairs'' varies depending on the animal, but in general There are 10 to 50 cotton hairs for each hair, and the fineness of the hair is 10 to 25 dr, and the fineness of the wavy hair is 5 to 50 dr.
This corresponds to 20 times more.

In addition, "sashige" is not crimped and has a thinner tip, so
It has a waist and a flexible feel, and the fiber length is "cotton hair".
It is about 1.5 times the fiber length.

The "cotton hair" has 5 to 20 crimps/inch and is 5000
It shows a density of ~50,000 pieces/Ca.

As a result of conducting various studies on the distribution, composition, and structure of the ``sash'' and ``cotton hair'' of such animal fur, the present invention was developed as follows: 1. Mixed into single fibers during spinning and used as "cotton hair".
The present invention can be completed by using fibers of Odr or less and easily obtaining a fur-like knitted fabric having a unique texture, luster, and color tone that are not found in conventional pseudo-fur by using the conventional flocking method or the piled knitting method. reached.

That is, the present invention uses polymer A and polymer B for the island component, polymer C which has a different solvent extractability from the island component as the sea component, and the island component is continuous in the fiber axis direction and the amount of component A and polymer B per single fiber is The denier of the component and the number of constituent pieces are each D.

Natural fur-like knitted fabric W) Production characterized by constructing a loop pile fabric using the flocking method or a piled knitted fabric so as to make this/crA, and extracting the sea component with a solvent after cutting the top of the loop pile. It is about law.

According to the present invention, it is now possible to easily obtain a knitted fabric having a unique natural fur-like texture, luster, and color tone not found in conventional products.

The sea-island structure fiber referred to in the present invention is produced by a special mixed spinning method in which two or more polymers are discharged from separate gear pumps, subjected to multilayering, joining, and dividing operations, and then collectively discharged from a nozzle. It can be obtained by a multi-core-to-sheath type mixed spinning method.

Examples of the A polymer and B polymer that constitute the island component of the sea-island structure fiber include polyester, polyamide, and polyacrylonitrile. For A polymer,
The B polymers corresponding to "fluff" may be of the same type or different types and may have a round or/and irregular cross section.

Furthermore, in order to impart crimpability and marbling effect, the B polymer is a high shrinkage type having a different intrinsic viscosity ([η]) from the A polymer, or a conjugate of two polymers with different [η], or a conjugate of two polymers with different [η]. It is also possible to use conjugates.

In particular, as shown in Figures 3 and 6 (the "cotton hair" of component B has a denier variation, it is desirable to have a natural look,
In special mixed spinning, the B component seen in Figures 4 to 6 is 2.
Those arranged in rows are easy to manufacture.

Polyester polymers are particularly desirable as the A polymer and the B polymer, such as aromatic dicarboxylic acids such as terephthalic acid, isophthalic acid, naphthalene-2,6-dicarboxylic acid, and phthalic acid; fatty acid dicarboxylic acids such as adipic acid and sebacic acid; It is a polyester synthesized from diol compounds such as esters of ethylene glycol, diethylene glycol, 1,4-dibutanediol, neopentyl glycol, and cyclohexane-4-dimetatool, and especially when 809L of the repeating unit is polyethylene terephthalate. Certain polyesters are preferred.

In addition, copolymerization of polyalkylene glycol, chrycerin, pentaerythritol, methoxypolyalkylene glycol, bisphenol A, sulfoisophthanolic acid, etc. to the above polyester component, or additives of up to 5% by weight, such as matting agents, heat stabilizers, Also included are those containing polyethylene glycol having a terminal group or dodecylbenzenesulfonic acid as a pigment or an antistatic property improver.

Examples of sea component polymers having different solvent extractability from the island component in the present invention include polyethylene, polystyrene, etc. These include, for example, tetrachloroethylene, trichlorethylene, toluene, xylene, n-hebutane, monochlorobenzene, tetrachloroethane, etc. It is easily extracted and removed.

Further, when a loop pile fabric is required to have good conjugation properties, it is particularly preferable to use polyethylene as the sea component because fibers with good conjugation properties can be easily obtained by heat fusion.

After the sea-island structure fiber used in the present invention is used as a loop pile yarn, the top of the loop pile is cut and the sea component is removed by solvent treatment to obtain the island component fiber. Must be continuous.

Furthermore, in order to approximate the look of natural fur, the denier DA of the A component corresponding to "hair" and the number X of constituent fibers per single fiber after stretching are DA = 3 to 20 dr, x = 1 to 4, In the B component corresponding to "cotton hair", DB
= 0.1~1. Odr, y = 10 to 80 and must satisfy 5≦DA//DB≦50.6≦y/x≦30, and if the above conditions are not satisfied, spinning and drawing may be carried out due to manufacturing technology. or the texture and tone are not similar to natural fur.Especially "cotton hair"
The B component of is 0.1 to 1. Odr is required and 0.1d
If r is not satisfied, there will be no waist, the compression recovery properties will be reduced, hair will be more likely to be removed, and the dyeability will be reduced.1. Odr
If it exceeds this, the unique texture and gloss that are the characteristics of the present invention will be lost, so it is not preferable.

The sea-island structure fiber has a multifilament size of 50 to 50
The yarn is spun and drawn at 0 dr, and when used as twisted yarn or pile yarn, it is pulled together to a total of 150 to 1500 yarns.

If it is less than 150 dr, it is difficult for the raised pile to sufficiently cover the ground tissue, and the flocking method requires a special tufting machine with fine needles. It becomes dense and loses its natural-like texture.

In addition, in order to give a natural fur look with denier irregularities and hair length distribution, it is also possible to create two or more types of sea-island structure fibers that have different hot water shrinkage rates of 4% or more during stretching, and mix them in appropriate amounts when used. .

Furthermore, in order to obtain a fiber with a high Young's modulus and no crimp, such as "sashimi", high-magnification drawing, constant length heat treatment, etc. can produce favorable results.

The sea-island structure fibers are used as pile yarns to be tufted into knitted or woven fabrics using conventional techniques, or knitted with fleece.
Use for the fleece yarn and pile yarn of woven fabrics such as plush knitting, or for the wool warp and fluff of woven fabrics such as double velvet weave, velveteen, kohl, and heaven, and create a loop pile with a loop pile density of 5 to 50 pieces/crA. After constructing the fabric, the top of the loop pile is cut to obtain a napped fabric.

In addition, if the loop pile density is less than 5 pils/crt, it is difficult for the piloes to sufficiently cover the ground tissue, and if it exceeds 50 pils/crrt, the piloes are not gripped enough and hair is easily removed (furthermore, there are too many piloes, resulting in a unique texture. damage.

Here, the loop pile density is the number (pieces) of loop piles present per crrl of fabric, and one loop pile is counted as one.

In this case, the knitted structure and the ground yarn constituting the woven structure may be of any material as long as it can withstand the sea removal component treatment and post-treatment conditions, and are preferably synthetic fibers such as polyester and nylon polyacrylonitrile.

In addition, in the flocking method and the piled knitted fabric, it is desirable that the knitted fabric be thick and somewhat dense in order to prevent the naps from falling off.

In addition, a backing agent (
A hard finishing agent) may be applied to the lining.

The napped knitted fabric obtained by this method is subjected to a sea removal treatment using the above-mentioned solvent at 60 to 90°C, so that the napped portions are reduced to only island component fibers.

Furthermore, if necessary, after descaling, relaxing (hot water treatment at 90-100℃), and presetting at 130-180℃ to fully develop the crimp of the B component of the "cotton hair", a light treatment is applied to align the tips of the hair. It is desirable to nap or brush.

In addition, during this process, in order to thin the tips of the hair, especially the "sashimi", to obtain a natural-like product with a soft touch and good compression recovery, for example, after melting the tips in the burning process, Another desirable method is to thin the tips of the hair by alkali or acid treatment.

After the napped knitted fabric is dyed by dip dyeing, thermosol method, printing, etc., it is finished by being lightly raised or brushed.

In finishing, hard finishing agents such as polyurethane, polyacrylic acid, and polyvinyl acetate, silicone, and cationic interfaces are used to improve texture, prevent hair loss, prevent static electricity, and provide stain resistance, as well as durability. Pad with a solution of aft mixture of softeners such as activators, as well as antistatic agents and antifouling agents such as acrylic acid derivatives, polyamide derivatives, fluorine compounds, ethylene oxide adducts, and polyester copolymers, and then brushing, drying, and heat treatment. It is preferable that the final finishing treatment be carried out such as napping, brushing, calendering, heat setting, etc.

By this method, for example, hair with thin tips and no crimps of 3 to 20 drO can be used as "puff hair" to have moderate crimps and a distribution of hair length.

, i~1. Odr covers the knitted fabric, resulting in a fur-like knitted fabric that has a unique texture with a soft touch and excellent compression recovery properties, as well as natural-like luster and color tone.

The present invention will be specifically explained below using Examples.

Example 1 and Comparative Examples 1 and 2 As the island component [η) -0,65ct17y (30°C using a mixed solvent of equal amounts of phenol and tetrachloroethane)
Using polyethylene terephthalate (intrinsic viscosity measured using an Utsperohde viscometer in a constant temperature bath), the A component of the island corresponding to "sashige" is 12 dr (denier) and 1
Book/1f (filament), B component is 0.8dr, 16
Book/if.

Polyethylene with a melting point of 115°C is used as the sea component, and four sea-island structure fibers consisting of six single yarns in which island components are substantially continuous with a sea-island ratio of 2:3 are twisted at 150 T/M to create a 985 d.
r and used as pile yarn for tufting.

The base fabric for tufting is 150dr/48f polyester processed yarn taffeta (warp density 128 threads/inch,
horizontal density of 95 pieces/inch), loop pile density of 2
After constructing a loop pile fabric with 5 pieces/cd, the top of the loop pile was cut to give a nap length of 18 mm.

Next, a urethane-based backing agent is applied to prevent the nape from falling off, and the sea component of the nape is removed using Perculen at 80°C, and after a slight nap is performed to align the ends of the hair in a certain direction, a thermosol method is applied. Dyeing, immersing in a finishing solution containing anti-hair removal agents (hard finishing agents), softeners, antistatic agents, etc., heat setting, unidirectional calendar rollers,
Brushing was applied to obtain an animal fur-like nap fabric.

The evaluation results are shown in Table 1. In addition, as Comparative Example 1, when the island B component of the pile yarn was set to 2 and Odr, and Comparative Example 2
As a result, we simultaneously evaluated the texture, hair removal state, etc. of a napped fabric in which the number of filaments per single fiber (filament) of component B was set to four.

The napped fabric obtained in Example 1 has an abundance of napped fibers, the level of cracking is grade A, and the napped fibers are easily compressed, but are easily recovered (the flocking angle is 20 to 40° due to calender roller peeling, and gloss appears). It had a texture similar to that of Japanese fur.

In addition, since the "cotton hair" of component B is extremely fine at 0.5 dr, it has a unique texture and color tone, resulting in a fabric with high commercial value with little hair shedding.

On the other hand, component B is 2. In Comparative Example 1, which has a large Odr and thick, the compression ratio of the nap was low, resulting in a fabric that is rougher and harder than in Example 1 and has a unique texture and luster. It is easy to see the ground structure and
Because there is little cotton wool, the fabric is coarse and stiff.

Example 2 As island component [η) -0.6dl/? using polyethylene terephthalate, A component is 2 pieces/if at 5 dr,
, the B component is 0.3 dr and 40 fibers/if, and the sea-island structure fibers are made of 12 single yarns using polyethylene as the sea component, and the drawn yarns have a hot water shrinkage rate of 10% and 5%.

The loop pile was cut into fluff.

Next, the seaweed component was treated in Triclean at 80°C, and then the knitted fabric was lightly raised twice using a needle cloth raising machine and dyed and finished to obtain a raised knitted fabric.

The obtained knitted fabric is rich in naps, and has an appropriate denier distribution and nap length distribution (20 to 40 mm) due to the difference in hot water shrinkage rate of the "sash hair" of the A component and the "cotton hair" of the B component, It had a rabbit-like texture, unique color tone, and luster.

In addition, the piloerection had a high compression rate and compression recovery rate (it was soft and firm).
