Cut-resistant yarn, fabric, cut-resistant sock and preparation methods thereof

Technical Field

The invention relates to the technical field of anti-cutting textile, in particular to anti-cutting yarns, fabrics, anti-cutting socks and preparation methods thereof.

Background

Ice hockey, also known as "hockey on ice," is a very competitive, high-resistance competitive sport that is very popular, especially in north america. Because the ice hockey is extremely fast in movement speed and severe in collision, the ice hockey is easy to damage the body of a sportsman, and in order to prevent injury in strenuous countermeasures, the sportsman needs to wear protective equipment in a whole body during training or competition. Protective equipment includes helmets, masks, shoulder guards, chest guards, waist guards, elbow guards, gloves, leg guards, ankle guards, and the like to protect various parts of an 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 calf, and plays a role in protecting the calf of an athlete and preventing tibia fracture. However, the conventional ice hockey leg protector is heavy and complicated, is troublesome to wear and cannot be bent, and in the running process, the leg protector easily slides along the legs, so that the accident that the skates scratch the lower legs of athletes easily occurs. Meanwhile, due to high-intensity sports, the athlete sweats a lot, and the hard plate material easily causes discomfort to the athlete's legs and feet. In addition, the existing leg protector only protects the tibia of the front part of the calf of the athlete, but does not protect the tissues such as muscles, ligaments, nerves, blood vessels and the like of the rear part of the calf. The tissues such as muscles, ligaments, nerves and blood vessels have a great influence on the athlete, and once damaged, the athlete may be permanently injured to stop career. Therefore, the enhancement of the protection of the rear part of the lower leg of the ice hockey player is particularly important, and the requirements on the ice hockey lower leg protection device are also higher.

Therefore, there is a need to develop a leg supporter that can protect both the lower legs of an athlete and can be worn conveniently and comfortably. Current research is generally carried out on the shield itself, and neglecting the need to directly wear socks on the athlete's feet and legs.

Cut-proof yarn

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

In view of the above characteristics of the aramid 1414, the present invention provides a cut-preventing yarn comprising an aramid composite material formed by wrapping a core material with an aramid 1414 (30 yarns) and a polyester spandex elastic yarn (150/40D) twisted together. The twisted aramid fiber composite material has the functions of cutting prevention, flame retardance, fastness enhancement and the like, and is suitable for being used as a raw material of protective products such as cutting prevention, flame retardance and the like.

Example 1

In the embodiment 1, aramid 1414 (30 pieces) 200 is used for wrapping and winding 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 dacron spandex elastic yarn is stranded with the aramid fiber cored steel wire by adopting a cladding winding process or a two-for-one twisting process.

The polyester spandex elastic yarn can be 3075FTY, is manufactured by adopting a process of adopting an S-direction twisting direction and a 480-twist twisting degree to process 10% of 75D polyester unidirectional coated 90% of 30D spandex yarn, and belongs to mechanical coated yarns.

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

s1: the aramid 1414 (30 pieces) 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 composite material can be formed by adopting a manufacturing process that the twist degree is 120 twists and the twist direction is Z twists.

S2: and plying the aramid composite material and the polyester spandex elastic yarn by adopting a two-for-one twisting process to form the anti-cutting yarn. During processing, a processing technology that the twist degree of polyester yarns is 560 turns, the twist direction is Z turns, the twist degree of spandex yarns is 560 turns, and the twist direction is Z turns can be adopted.

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

Example 2

Alternatively, the core material can be customized and changed into an inner core with inorganic fibers such as glass fibers, basalt fibers, ceramic fibers, quartz fibers and the like according to the application. The core material can adopt any of the inorganic fibers from 65tex to 90 tex. In the embodiment 2, aramid 1414 (30 counts) is adopted to wrap 65tex-90tex inorganic fibers to form an aramid composite material. The preparation process is the same as that of example 1, and will not be described here again.

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

As can be seen from the above table, the aramid fiber 1414 (30 pieces) is wrapped and wound with 0.035MM steel wire or 65-90 tex inorganic fiber to form an aramid fiber composite material, which has the characteristics of high cutting resistance index, softness, easiness in braiding and the like.

Cut-resistant fabric

The invention also provides a cut-preventing fabric which is made of the cut-preventing yarns of the aramid composite material. The cut resistant fabric is very unique in machine configuration compared to conventional fabrics. According to the looping principle of a weft knitting machine, the situation that a knitting needle is blocked and broken due to overlarge knitting needle can occur; the knitting needles are too small to install and use the cut-preventing yarn. The invention utilizes 20-level knitting needles to weave the anti-cutting fabric by a method of oblique knitting or plain knitting on a circular knitting machine of a common hosiery machine.

As shown in fig. 3A, the black solid line portion in fig. 3A represents the conventional knitting needle 400, and the gray dotted line portion represents the modified 20-stage knitting needle 300 used in the present invention. As can be seen in fig. 3B, the knitting needle 300 used in the present invention includes a butt 306, a wavy structure 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, lengthens the length of the butt 306, and changes the relatively smooth structure of the conventional knitting needle 400 at the portion of the needle bar 305 near the butt 306 into the wavy structure 301, protruding upward in the direction of the butt 306, thereby forming the groove 302 in the opposite direction to the butt 306. The traditional knitting needle has the advantages that the butt is short, one end of the needle bar close to the butt is smooth, the acting force is small, and the knitting needle cannot move or the moving distance is limited after entering the hosiery machine. According to the invention, after the knitting needle 300 enters the sock knitting machine, through the lengthened butt 306 and the groove 302 formed at the end part of the needle bar 305, the groove on the needle bar is convenient for hooking, so that the knitting needle can firmly clamp the needle cylinder, and the knitting needle can move in the vertical direction under the action of the needle cylinder, and the movement range is larger.

The 20-stage knitting needle 300 according to the present invention shown in fig. 3B is preferably made of stainless steel, as shown in fig. 4, in which 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 longitudinal 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 8mm. The length L3 from the end of the latch 304 in the open state to the curved peak of the hook 303 is 12.9mm, the length L4 from the curved peak 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 of the latch 304 in the closed state is 3.14mm.

The following is a table of machine model and parameters.

Table 2 comparison table of cut-preventing fabrics and general fabrics

	Cut-resistant fabric machine model and parameters	Model and parameters of common fabric machine
			Number of needles and needle pitch of hosiery machine	144N/12 stage	144N/12 stage
Knitting needle use	20 grade	18 grade
			Caliber of needle cylinder	3 3/4”	3 3/4”
Rotational speed	150-180r/min	150-180r/min
			Main function	Computer jacquard terry	Computer jacquard terry

The number of needles of the loom for producing the cut-resistant fabric is 144N, the caliber of the needle cylinder is 3.75 inches, and the number of the loom is 12.2G, which is generally calculated by the following formula:

G=E/T (G- - -machine number, T- - -cylinder circumference, E- - -number of needles)

G＝144/(3.75*3.1415)＝12.2G

According to the information of a 'knitting engineering handbook-weft knitting division (2 nd edition)' published by Chinese textile publishing company, the density of raw material lines which can be processed on a stocking machine with a certain machine number has a certain range, and the raw material lines can not be knitted on a corresponding machine beyond the density range.

Fig. 6 is a graph showing the relationship between the machine tool of the hosiery machine and the linear density of the processed material described in the prior art document.

Comparison of cotton yarn corresponding to machine number in tables 3-1-12 of fig. 6:

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

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

The main yarn raw materials used for the anti-cutting fabric are as follows: the 30S aramid fiber plus 0.0036mm steel wire and 150/40D ply polyester/polyurethane elastic wire are equal to 12S, and when the cutting prevention part is woven, two strands of main yarn raw materials are simultaneously fed, so that the two strands are equal to 6S.

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

d=5315/S, i.e. d=5315/6= 885.8D

1 tex=0.111D i.e. tex=0.111 x 885.8=98.3 tex

Conclusion: i.e. the cut resistant fabric uses 98.3tex main yarn, much more than the conventional cotton yarn density of this machine of 64tex, exceeding 53.6%.

The invention utilizes the existing common hosiery machine, only combines the use of the specific knitting needle and the fine adjustment of the related parts of the hosiery machine, and feeds the shuttle of the hosiery machine into the hosiery needle for knitting, thereby not only meeting the requirement of high-index cutting prevention, but also considering the manufacturing cost, reaching the limit on the utilization of the common hosiery machine, overcoming the technical problem and leading the common hosiery machine to be capable of knitting the cutting prevention fabric which cannot be knitted originally.

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

The specific test method comprises the following steps: a small rectangular sample of glove material is placed on a metal mandrel of a cutting test apparatus, which is traversed by a special blade in the direction of the sample until the sample is penetrated. When the blade penetrates the sample and is in electrical contact with the metal mandrel, the cut-prevention test device measures the distance that the blade moves before penetrating the sample. This distance of movement of the blade is determined by the different weights of the load on the arm of the experimental device in which the blade is clamped. Thus, the test results are generally defined as determining the weight required for the blade to penetrate the cut-resistant sock material over a distance of 20 mm. The greater the weight, as measured by this test method, indicates a greater cut-resistant performance of the glove material.

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

Grade	The blade moves 20mm of the weight (grams) required to penetrate the material
		A1	≥200
A2	≥500

A4	≥1500
		A5	≥2200
A6	≥3000
		A7	≥4000
A8	≥5000
		A9	≥6000

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

The cut-preventing fabric disclosed by the invention can be made into various products in special fields, such as cut-preventing gloves, hats, masks, work clothes and the like of labor protection equipment, gloves, socks, knee pads, sports clothes and the like of sports protection equipment, helmets, gloves, knee pads, military equipment and the like of military equipment.

Cut-proof socks

Referring to fig. 2, the present invention further provides a cut-preventing sock, which comprises a cut-preventing portion 1, a rib cuff 2, a sole support 3, a leg 4, a foot 5, a toe 6, and a heel 7, wherein the cut-preventing portion 1 is formed by the above cut-preventing fabric, and is located at one or more different portions corresponding to the sole, the instep, the ankle, the shank, the knee, the thigh, etc. of a wearer, which need to be protected, and covers the muscle, ligament, nerve, blood vessel, etc. tissues of the foot or leg of the wearer, thereby protecting the same.

The anti-cutting part 1 and other parts of the anti-cutting sock can be integrally woven or sewn after being cut by the anti-cutting fabric and other parts of the anti-cutting sock.

The preparation process of the anti-cutting sock comprises the following steps of:

w1: mounting a 20-level knitting needle on a circular knitting machine;

w2: and placing the cut-preventing yarn on a stocking machine to weave cut-preventing stockings, and sewing the stocking heads after weaving.

In the step W2, the method specifically includes placing the cut-preventing yarn on a stocking machine, knitting according to a program pattern knitted by a computer, reversing the stocking after knitting, sewing the stocking head by using a sewing machine, checking the stocking after sewing, then setting, namely setting the stocking plate correctly, tidying the stocking, then feeding the stocking into the setting machine, controlling setting time by adopting proper temperature and pressure, and finishing the stocking after setting.

In the step of W2, the anti-cutting yarn is 3075FTY core spun yarn, and when a circular knitting machine is used for knitting the anti-cutting part of the anti-cutting sock, the anti-cutting yarn is added into the conventional yarn to knit the anti-cutting part; and after the knitting is finished, withdrawing the anti-cutting yarn, and knitting other parts of the anti-cutting sock by using the conventional yarn.

Alternatively, in the above W2, the whole cut-preventing sock may be knitted by using the cut-preventing yarn of the present invention.

Or, the cut-preventing fabric of the present invention is cut according to the shape of the cut-preventing portion of the cut-preventing sock and then sewn.

The cross-draw index represents the length of the fabric that is drawn from a line of 0 on a cross-draw machine, i.e., the length that the fabric can be cross-drawn to stretch. The cut-preventing socks sewn by the cut-preventing fabric have very good cut-preventing performance, taking 10-13 size as an example, the transverse pull index of the position of the rib top 2 is 23CM, the transverse pull index of the position of the sock leg 4 is 22.5CM, the transverse pull index of the cut-preventing position 1 is 20CM, the transverse pull index of the sock leg 5 is 22CM, and the rib top 2 can be transversely stretched by 23CM, the sock leg 4 can be transversely stretched by 22.5CM, the cut-preventing position 1 can be transversely stretched by 20CM and the sock leg 5 can be transversely stretched by 22 CM. Therefore, the extension length of the anti-cutting part 1 is obviously smaller than that of other parts, but the transverse pulling index of the whole anti-cutting sock is far greater than that of the common knitted sock 15, so that the whole elasticity of the anti-cutting sock is greatly improved, and meanwhile, each part of the square-cutting sock has different transverse pulling parameters according to the characteristics and different requirements of the feet of a wearer.

The anti-cutting sock is particularly suitable for ice hockey players. Because the anti-cutting socks are formed by weaving the anti-cutting yarns of the aramid fiber composite material, compared with the existing leg guard, the anti-cutting socks are softer and more breathable in wearing feeling, the wearing method is simple and convenient, the movement flexibility of a wearer is more facilitated, and the comfort level is greatly improved.

In consideration of the fact that the special high-strength anti-cutting material is used at the anti-cutting part of the anti-cutting sock, the method adopts a mode that the yarn at the anti-cutting part and the yarn at the common part are woven into two courses at the same time at the joint of the anti-cutting part and the common yarn, so that a better transition effect is achieved, and the phenomenon that the common yarn is broken by the rigid-strength aramid composite material in severe friction is avoided, and the fabric structure shown in a square frame of fig. 8 is formed.

The anti-cutting sock disclosed by the invention has the anti-cutting index reaching the 5-grade requirement of the American ANSI/ISEA 105-2016 standard, approaches to 6-grade, obtains approval and recommendation of the American hockey ball alliance, and agrees that the anti-cutting sock enters the American hockey ball alliance to be used as a necessary product for hockey players.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
