Anti-cutting yarn, fabric, anti-cutting socks and preparation method thereof

Technical Field

The invention relates to the technical field of cutting-resistant textiles, in particular to cutting-resistant yarns, fabrics, cutting-resistant socks and a preparation method thereof.

Background

Ice hockey, also known as "hockey puck", is a highly competitive, highly antagonistic competitive athletic sport, particularly in north america, and is very popular. Because the speed of the ice hockey is extremely fast and the impact is violent, the ice hockey is easy to hurt the body of the sportsman, and the sportsman needs to wear the protective clothing all over in the training or the competition in order to prevent the sportsman from being injured in the tense and violent confrontation. Protective equipment includes helmets, masks, shoulder pads, chest pads, waist pads, elbow pads, gloves, leg pads, ankle pads, etc. to protect various parts of the athlete's body.

At present, the existing leg protector is mostly made of hard plates such as plastic plates and the like, is worn on the front part of the shank and plays the roles of protecting the shank of an athlete and preventing the fracture of the tibia. However, the conventional hockey leg protector is heavy and complicated, is troublesome to wear, cannot be bent, is easy to slide along the leg during running, and is easy to cause an accident that the ice skate scratches the lower leg of a player. Meanwhile, due to high intensity sports, athletes sweat a lot, and hard boards easily cause discomfort of the legs and feet of the athletes. In addition, the existing leg protector only protects the shin bone at the front part of the lower leg of the athlete, but does not protect the tissues of muscles, ligaments, nerves, blood vessels and the like at the rear part of the lower leg. The tissues such as the muscles, ligaments, nerves and blood vessels have a great influence on athletes, and once the athletes are damaged, the athletes can be permanently injured to stop their careers. Therefore, the protection of the rear part of the lower leg of the hockey player is particularly important to be enhanced, and higher requirements are also put forward for the lower leg protector of the hockey player.

Therefore, there is a need to develop a leg protector which can protect the lower leg of the athlete and can be worn conveniently and comfortably. Current research is generally placed on the cover itself, and research into socks worn directly on the feet and legs of athletes has been ignored.

Anti-cutting yarn

para-aramid-PPTA fibers, also known as aramid 1414, are known because their molecular structure amide groups are para (1,4) to the benzene ring. Due to the rigidity of molecular chains and lyotropic liquid crystallinity, an anisotropic texture is easily formed in a solution under the action of shearing force. Has high heat resistance, the glass transition temperature is above 300 ℃, the thermal decomposition temperature is up to 560 ℃, and the strength retention rate is 84 percent after the glass fiber is placed in air at 180 ℃ for 48 hours. The high tensile strength and initial elastic modulus, the fiber strength is 0.215N/denier, the modulus is 4.9-9.8N/denier, the specific strength is 5 times of that of steel, and the compression strength and the bending strength of the composite material are only lower than those of inorganic fibers. Stable thermal shrinkage and creep properties, high insulation and chemical resistance.

In view of the characteristics of the aramid fiber 1414, the invention provides the anti-cutting yarn which is formed by plying the aramid fiber composite material formed by wrapping and winding the core material with the aramid fiber 1414(30 yarns) and the polyester spandex stretch yarn (150/40D). The twisted aramid fiber composite material has the functions of cutting resistance, flame retardance, fastness enhancement and the like, and is suitable for being used as a raw material of protective products such as cutting resistance, flame retardance and the like.

Example 1

In this embodiment 1, aramid fibers 1414(30 pieces) 200 are wrapped and wound around 0.035MM steel wires 100 to form an aramid composite material. Referring to fig. 1, the core material is a steel wire having a diameter of 0.035 MM. The polyester spandex stretch yarn is stranded with the aramid core-spun steel wire by adopting a cladding winding process or a two-for-one twisting process.

The polyester spandex elastic yarn can be 3075FTY, is prepared by coating 10% of 75D polyester one-way by 90% of 30D spandex yarn and adopting the process of S-direction twist and 480-twist, and belongs to mechanical coated yarn.

The preparation method of the anti-cutting yarn of the embodiment comprises the following steps:

s1: the aramid fiber 1414(30 yarns) is wrapped and wound on the outer surface of the core material by adopting a wrapping and winding process or a two-for-one twisting process, and the aramid fiber composite material can be formed by adopting a manufacturing process that the twist number is 120 twists and the twist direction is Z twists.

S2: the aramid fiber composite material and the polyester spandex stretch yarn are plied by adopting a two-for-one twisting process to form the anti-cutting yarn. During processing, a processing technology that the twist of polyester yarn is 560 twists, the twist direction is Z twists, the twist of spandex yarn is 560 twists, and the twist direction is Z twists can be adopted.

The anti-cutting yarn prepared by the process has high toughness, strength and flexibility, and is suitable for preparing a weaving anti-puncturing and anti-cutting material.

Example 2

Alternatively, the core material can be customized and changed into inorganic fibers such as glass fibers, basalt fibers, ceramic fibers, quartz fibers and the like as the inner core according to the application. The core material may use any of the above-mentioned inorganic fibers of 65tex to 90 tex. In this example 2, aramid 1414(30 pieces) is used to wrap and wind 65tex-90tex inorganic fiber to form an aramid composite material. The preparation process is the same as that of example 1, and is not described herein again.

TABLE 1 mechanical Properties of aramid core-spun Steel wire/aramid core-spun inorganic fiber

As can be seen from the table above, the aramid composite material formed by wrapping and winding 0.035MM steel wires or 65tex-90tex inorganic fibers with the aramid 1414(30 pieces) has the characteristics of high cutting resistance index, softness, easiness in weaving and the like.

Anti-cutting fabric

The invention also provides a cutting-proof fabric which is made of the cutting-proof yarns made of the aramid fiber composite material. Compared with the conventional fabric, the cutting-proof fabric has great originality on the machine configuration. According to the looping principle of the weft knitting machine, the situation of machine blocking and needle breakage can occur when a knitting needle is too large; the knitting needle is too small, and the cutting-preventing yarn cannot be installed and used. The invention utilizes 20-grade knitting needles on a circular knitting machine of a common hosiery knitting machine to weave the anti-cutting fabric by adopting a slant knitting or flat knitting method.

As shown in fig. 3A, the solid black portion of fig. 3A represents the conventional knitting needle 400, and the dashed gray portion represents the modified 20-step knitting needle 300 used in the present invention. As can be seen from fig. 3B, the knitting needle 300 used in the present invention includes a butt 306, a wave 301, a shank 305, a hook 303, a latch 304, and a latch pin 307.

As can be seen from fig. 3A, the present invention improves the structure of the knitting needle 300 on the basis of the prior art, the length of the butt 306 is lengthened, and the portion of the shank 305 adjacent to the butt 306 is changed from the relatively smooth structure of the conventional knitting needle 400 to the wavy structure 301, protruding upward in the direction of the butt 306, so that the groove 302 is formed in the opposite direction to the butt 306. The traditional knitting needle is short in needle butt, one end of the needle rod close to the needle butt is smooth, acting force is small, and the knitting needle cannot move or the moving distance is limited after entering a hosiery machine. According to the invention, the lengthened needle butt 306 and the groove 302 formed at the end part of the needle bar 305 are adopted, so that after the knitting needle 300 enters the hosiery machine, the groove on the needle bar is convenient to hook, the knitting needle firmly clamps the needle cylinder, the needle cylinder moves in the vertical direction under the action of the needle cylinder, and the moving range is large.

In the 20-grade knitting needle 300 of the present invention shown in fig. 3B, as shown in fig. 4, preferably, the knitting needle 300 is made of stainless steel, the length L1 from the butt 306 to the hook 303 is 71.16mm, the length L2 from the side of the butt 306 facing the hook to the hook is 68.2mm, the width of the butt 306 in the length direction of the knitting needle 300 is 2.96mm, and the thickness of the knitting needle 300 in the inward depth direction of fig. 4 is 8 mm. The length L3 from the lower end portion to the curved vertex of the hook 303 in the open state of the latch 304 is 12.9mm, the length L4 from the curved vertex of the hook 303 to the hook tip is 1.97mm, the width H1 of the hook 303 is 2.09mm, the width H2 from the bottom of the latch pin 307 to the tip of the hook 303 is 2.77mm, and the width H3 from the bottom of the latch pin 307 to the tip in the closed state of the latch 304 is 3.14 mm.

The following is a comparison table of machine models and parameters.

TABLE 2 comparison of cut-resistant fabric and plain fabric

	Machine model and parameters for cut-resistant fabrics	Machine model and parameters of plain fabric
			Hosiery machine needle number and needle pitch	144N/12 stage	144N/12 stage
Use of knitting needles	20 stage	18 stages
			Needle cylinder caliber	3 3/4”	3 3/4”
Rotational speed	150-180r/min	150-180r/min
			Main function	Terry computer jacquard	Terry computer jacquard

The loom needle count for producing this cut resistant fabric was 144N, the cylinder gauge was 3.75 inches, and the loom size was 12.2G, which was generally calculated as follows:

g ═ E/T (G- - -number, T- - -cylinder circumference, E- - -number of needles)

G＝144/(3.75*3.1415)＝12.2G

According to the data published by the Chinese textile Press in the handbook of knitting engineering-weft knitted booklet (2 nd edition), the density of raw material threads that can be processed on a certain number of hosiery machines has a certain range, and beyond the density range, the raw material threads cannot be knitted on the corresponding machine.

FIG. 6 is a graph showing the relationship between the linear density of the hosiery machine table and the processing material, which is described in the technical documents in the prior art.

Comparison with cotton yarn corresponding to the machine numbers in tables 3-1-12 of FIG. 6:

conventional 14.5G machine size, cotton yarn fabric corresponds to main yarns: 2 x 14tex 2

Converting the number into a 12.2G machine number, the corresponding main yarns of the cotton yarn fabric are as follows: 2 x 16tex 2, i.e. 64tex

The main yarn raw materials used by the anti-cutting fabric are as follows: 30S aramid fiber +0.0036mm steel wire and 150/40D twisted polyester spandex yarn are equal to 12S, and when the anti-cutting part is woven, two strands of the main yarn raw material are simultaneously fed, and the main yarn raw material is equal to 6S.

According to the conversion relation between the English counts and the tex, converting the 6S into the corresponding tex, and then:

5315/S, i.e., D-5315/6-885.8D

1 tex-0.111D, that is, tex-0.111-885.8-98.3 tex

And (4) conclusion: that is, the cut resistant fabric uses a primary yarn of 98.3tex, which is much greater than the conventional cotton yarn density of 64tex for this machine, over 53.6%.

The invention utilizes the prior common hosiery knitter, only uses a specific knitting needle, combines with the fine adjustment of the relevant parts of the hosiery knitter, and feeds the hosiery needle to knit through the shuttle of the hosiery knitter, thereby not only meeting the requirement of high index cutting prevention, but also considering the manufacturing cost, achieving the limit of the utilization of the common hosiery knitter, overcoming the technical problem and leading the common hosiery knitter to knit the cutting-prevention fabric which can not be knitted originally.

FIG. 7 is a specification of the American ANSI/ISEA 105-2016 standard for testing cut resistance

The specific test method comprises the following steps: a small rectangular sample of glove material was placed on a metal mandrel in a cut-off test apparatus which was traversed in the direction of the sample using a special blade until the sample was penetrated. When the blade penetrates the sample and is in electrical contact with the metal mandrel, the cut-resistant testing device measures the distance the blade travels before penetrating the sample. This distance of movement of the blade is determined by the different weights loaded on the arm of the experimental device holding the blade. Thus, the test results are generally defined as determining the weight required for the blade to penetrate the cut-resistant sock material across a distance of 20 mm. As a result of the test method, a greater weight indicates a higher cut resistance of the glove material.

TABLE 3 American ANSI/ISEA 105- & 2016 Standard cut-resistant index rating Table

Grade	Weight (g) required for the blade to move 20mm through the material
		A1	≥200
A2	≥500
		A3	≥1000
A4	≥1500
		A5	≥2200
A6	≥3000
		A7	≥4000
A8	≥5000
		A9	≥6000

According to the detection requirement of ANSI/ISEA 105-2016 standard, the composite material formed by the aramid core-spun steel wire with the structure is tested, and the results are shown in the following table:
