Description

[Technical Field]

[0001] The present invention relates to a towel having pile. [Background technology]

[0002] Towels have a pile surface formed by pile yarns protruding from the surface, and are soft to the touch, highly absorbent, and popular as cloth personal items. Colors can be achieved by dyeing. While synthetic fibers such as polyester are sometimes used for towel fabric, cotton yarn is often used for its absorbency and soft feel.

[0003] Patent Document 1 describes a towel product in which pile yarn is made of untwisted yarn formed from fibers having a fiber length of 35 mm or more. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 7-216762 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional towels that use cotton yarn as pile yarns experience a certain amount of lint shedding. Patent Document 1 claims that lint shedding can be reduced by using untwisted yarns formed from fibers with a fiber length of 35 mm or more as the pile yarn. However, cotton also contains fibers shorter than this, and using only fibers longer than 35 mm would result in a large amount of wasted fiber, wasting resources and increasing product costs. Furthermore, the pile length is limited to 5 to 10 mm.

[0006] An object of the present invention is to provide a towel fabric or towel product that has high water absorption, is bulky, has a glossy feel, and is less likely to shed fluff. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the method for producing pile yarn for towels of the present invention comprises the steps of singeing a cotton yarn with a flame of a burner while the cotton yarn is running; The cotton yarn is then combined with a water-soluble yarn and untwisted to form a composite yarn, preferably by passing the yarn through an aqueous sodium hydroxide solution while being drawn.

[0008] The pile yarn for towels of this invention is a composite yarn obtained by singeing a running cotton yarn with a burner flame, running the running cotton yarn through a sodium hydroxide aqueous solution while stretching it, and then untwisting it together with a water-soluble yarn. The raw yarn is preferably a cotton yarn having a count of 10 to 20, made from a combination of fibers with lengths of 35 to 40 mm and fibers with lengths of 25 to 30 mm, and a twist number of 10 to 20 turns per inch. It is particularly preferred that the raw yarn is a cotton yarn having a count of 16, made from a combination of fibers with lengths of 37 mm and fibers with lengths of 29 mm, and a twist number of 15.5 turns per inch.

[0009] Furthermore, the towel fabric of this invention uses the above-mentioned towel pile yarn as the pile yarn, with a warp yarn of 40-count two-ply cotton yarn and a weft yarn of 30-count single cotton yarn, and is a plain weave with a warp density of 30 to 35 ends per inch, a weft density of 30 to 35 ends per inch, and a pile length of 10 mm to 15 mm. It is particularly preferable that the warp density is 32.3 ends per inch and the pile length is 11 mm to 12 mm. [Effects of the Invention]

[0010] The towel pile yarn of this invention has little fuzz and a high luster. By weaving this yarn as pile yarn, a towel fabric with excellent bulk and good dyeability can be obtained. [Brief explanation of the drawings]

[0011] [Figure 1] 1 is a flow chart showing a method for manufacturing pile yarn for towels. DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will now be described. Fig. 1 is a flow chart showing an outline of a method for manufacturing pile yarn for towels.

[0013] The raw material for towel pile yarn is spun cotton yarn CY0. The cotton yarn CY0, which is the raw yarn, preferably has a count of 10 or more and 20 or less. This cotton yarn may contain short fibers in addition to long fibers. For example, it may contain both long fibers of 35 mm or more and 40 mm or less and short fibers of 25 mm or more and 30 mm or less. The fiber length here is a value measured using the double sorter method of JIS L1019:2006. A cotton yarn containing approximately 37 mm fibers and approximately 29 mm fibers at 50% each, with a count of 16, is particularly preferred, and this was the yarn used in this example.

[0014] The fluff singeing process Q1 is carried out on CY0. The cotton yarn CY0 is run while being exposed to a burner flame, and the fluff is burned off, thereby reducing the number of fluffs.

[0015] After the singeing process Q1, cotton yarn CY1 undergoes chemical treatment process Q2. Tension is applied to cotton yarn CY1, stretching it as it passes through a sodium hydroxide solution. The yarn is stretched and run using an upstream delivery roller and a faster downstream tension roller, with the yarn passing through a bath of sodium hydroxide solution between them. This process swells the cotton fibers, smoothing their surface and improving parallelism, resulting in a highly lustrous yarn. Stretching also makes cotton yarn CY1 slightly thinner.

[0016] After the chemical treatment step Q2, the cotton yarn CY2 is subjected to the detwisting step Q3. The cotton yarn CY2 is combined with the water-soluble yarn Y, and the cotton yarn CY2 and the water-soluble yarn Y are twisted in the opposite direction to the twist of the cotton yarn CY2. For example, if the original cotton yarn CY0 has a Z twist, it is twisted with an S twist. This forms a composite yarn in which the water-soluble yarn Y is wrapped around the cotton yarn CY2, further reducing the twist of the cotton yarn CY2. The detwisting is performed to a level that is called a no-twist yarn. For example, if the original cotton yarn CY0 has a twist of 14.5 turns per inch, it is preferable to adjust the twist after detwisting to a range of +4 turns per inch to -4 turns per inch. The adjustment range for the detwisting of the no-twist yarn is ±6%, and the S / Z ratio is 1.06. The composite yarn obtained by the detwisting step Q3 becomes the pile yarn for towels of this invention.

[0017] The resulting towel pile yarn is soft, shiny, and highly absorbent. The number of fluffs with a fluff length of 3 mm or more is extremely low, at 136 times per inch.

[0018] Next, we will explain towel fabrics using the above-mentioned towel pile yarns and their weaving. The warp yarns (ground yarns) and weft yarns can be selected as appropriate, but it is preferable to use cotton yarns. The pile yarn P is preferably obtained from cotton yarns with a count of 10 to 20, which are a combination of fibers with a fiber length of 35 to 40 mm and fibers with a fiber length of 25 to 30 mm. This is woven into towel fabrics using a towel loom. It is preferable that the warp density be 30 to 35 threads / inch, the weft density be 45 to 55 threads / inch, and the pile length be 10 to 15 mm. It is particularly preferable that the warp density be 33 threads / inch and the pile length be 11 to 12 mm.

[0019] For example, pile yarn P obtained from 16 count raw yarn CY0 is used, and the warp yarn is 40 count two-ply cotton yarn, and the weft yarn is 30 count single-ply cotton yarn, with a warp density of 33 threads / inch (reed 48 count) and a weft density of 50 threads / inch, for a plain weave. The woven towel fabric is washed in hot water to dissolve and remove the water-soluble pile yarns.

[0020] The resulting towel fabric is soft, highly absorbent, and voluminous. It also has a glossy finish and good dyeability. It also resists shedding. It can be used to make towel products such as handkerchiefs, face towels, sports towels, and bath towels.
