Description

Tearable towel fabric and production method and equipment thereof TECHNICAL FIELD

[0001] The present application relates to the field of daily necessities, in particular to a tearable towel fabric and its production. BACKGROUND

[0002] Towels are different from conventional non-woven fabrics and other solutions. Towels are usually made of cotton or synthetic fibers, and have better water absorption and softness than non-woven fabrics and paper towels. The patent application of our company with publication number CN115444300A is the closest prior art, which uses ultrasonic hot melting to form a tear line. The hot melting is synchronized with the formation of the terry pile, so the tear line is obviously located on the entire towel roll. After tearing, the hot melting part is located at the edge of the towel fabric. Due to the brittle nature of the tear line after hot melting, the edge of the towel fabric has a sharp touch and poor hand feeling, which can easily scratch the wiping surface. The soft hand feeling and touch are a big advantage of towels. The sharp edge of the hot-melted tearable towel roll affects the overall quality of the towel. Therefore, there is an urgent need for a towel fabric and a towel production method and equipment that solve the above technical problems. TECHNICAL PROBLEM

[0003] The sharp edge of the tear line of the tearable towel fabric affects the overall hand feeling of the towel. TECHNICAL SOLUTION

[0004] In order to solve the problem of the sharp edge of the tear line of the tearable towel fabric affecting the overall hand feeling of the towel, the present application provides a tearable towel fabric with a soft edge and a production method and equipment.

[0005] The present application has the advantages that: the tearable towel fabric uses an empty needle to reduce the thickness of the hot-melted edge and the thickness of the tear line; after the towel fabric is split into single pieces along the tear line, the terry pile expands to cover the tear line, forming single towels with soft edges and soft hand feeling. The production of raw materials with empty needle stitches is suitable for subsequent cutting design of the tear line and reduces the volume of the tear line after melting; the tear line is sparsely arranged along the tear line, effectively realizing ultrasonic hot melting and hot cutting of the narrow tear line. The sparse mechanism ensures the position of ultrasonic hot cutting and ultrasonic hot melting along the empty needle stitch and prevents the surrounding terry pile from invading the empty needle stitch; the terry pile is sprayed and humidified before combing, effectively improving the combing effect.

[0006] The technical scheme adopted by the present application is: a tearable towel fabric, comprising a base fabric, the base fabric is provided with terry piles, the terry piles can be double-sided or single-sided according to requirements, the towel fabric is provided with a tear line for tearing into single pieces, adjacent terry pile fabrics are provided with an empty needle stitch without terry piles, the tear line is formed by hot melting and pressing along the empty needle stitch using ultrasonic waves, and the terry pile on the surface of the towel has an expanded area that exceeds the area of the base fabric.

[0007] As a preferred solution of the tearable terry cloth, the distribution of the loops has two single-sided and double-sided, the loops are arranged on the upper and lower end surfaces of the base cloth. The loops are arranged on one end surface of the base cloth. After the terry cloth is split into single pieces, the loops will expand to cover the tear line, forming a single piece of terry cloth with soft edges around the perimeter.

[0008] As one of the preferred solutions of the tearable terry cloth, the terry cloth is arranged in a roll.

[0009] As one of the preferred solutions of the tearable terry cloth, the terry cloth is formed by cutting at least one terry cloth width of cloth on both sides by an ultrasonic cutting mechanism, the cutting part has no loops arranged, and the cutting part is formed by the ultrasonic cutting mechanism. After cutting, an edge is formed, and the loops on the terry cloth are spread to cover the edge.

[0010] A production method of a tearable terry cloth, comprising the following steps: A, forming a raw cloth to be processed, the raw cloth is provided with longitudinal and transverse intersecting empty needle stitches for dividing the raw cloth into a plurality of terry cloths; B, using an ultrasonic cutting machine to cut the raw cloth into at least one continuous terry cloth strip along the empty needle stitches; C, using an ultrasonic hot melting device to hot melt the empty needle stitches on both sides of the terry cloth strip to form a tearable terry cloth; D, arranging the tearable terry cloth in a roll.

[0011] A production device of a tearable terry cloth, comprising a feeding device for processing raw materials, an ultrasonic cutting mechanism, and an ultrasonic hot melting device; the ultrasonic cutting mechanism comprises a roller and an ultrasonic generating head matched with the roller, and the front end of the ultrasonic cutting mechanism is provided with a carding mechanism; the structure of the ultrasonic hot melting device is the same as that of the ultrasonic cutting mechanism, but the power is different; the carding mechanism comprises a sharp part extending into the empty needle stitch and a guide plate extending backward and inclined from the sharp part.

[0012] According to the different needs of double-sided and single-sided terry cloth processing, the carding mechanism has two groups arranged at the front end of the roller and the front end of the ultrasonic generating head.

[0013] In order to further ensure that the loops at the empty needle stitches are not hot melted, a spraying mechanism is arranged at the front end of the ultrasonic cutting mechanism and the ultrasonic hot melting device, and a humidification treatment is adopted.

[0014] As one of the preferred solutions of the production device of the tearable terry cloth, the device further comprises a tearable terry cloth winding device, and a drying mechanism located between the ultrasonic hot melting device and the tearable terry cloth winding device. Advantages

[0015] The present application has the beneficial effects that: the tearable towel fabric adopts the empty needle, reduces the thickness of the hot melt cutting edge and the thickness of the tearing line; after the towel fabric is split into single pieces along the tearing line, the terry pile expands to block the tearing line, forming a single towel with soft hand feeling and no hand injury around; the original fabric with the empty needle line is suitable for the subsequent cutting design of the tearing line and reduces the volume of the melting tearing line; the sparse division mechanism is arranged along the tearing line, effectively realizing the ultrasonic hot melting and hot cutting process of the narrow tearing line; the spraying is used for humidifying the terry pile before the carding, effectively improving the carding effect.
